Short title: Walking aids, activity and participation
ABSTRACT
Objective: Examine how walking aids (canes, crutches, walkers and rollators) enable
activity and participation among adults with physical disabilities.
Data sources: Medline, Embase, all EBM reviews, PsychInfo, CINAHL and Web of
Science databases were used to identify studies published since 2008. Quantitative and
qualitative designs were included.
Data extraction: Data regarding participants, assistive device use, outcome measures and
domains of participation were extracted. Two reviewers independently rated the level of
evidence and methodological quality of the studies. Outcomes were categorized per types
of walking aids and domains of activity and participation.
Data synthesis: Thirteen studies were included. Two involved canes, four pertained to
rollators and seven dealt with multiple types of walking aids. Mobility was the most
frequently examined domain of activity and participation. Both negative and positive
results were found. Negative outcomes were linked to the physical characteristics of the
device, the use environment and personal reluctance. When incorporated in daily life,
walking aids were found to enable several domains of activity and participation.
Conclusion: Whether walking aids facilitate activity and participation may depend on the
user’s ability to overcome obstacles and integrate them in daily life. More high-quality
research is needed to draw conclusions about their effectiveness.

INTRODUCTION
Adults with physical disabilities face activity and participation challenges (1-5)
that can influence their level of life satisfaction (6). To overcome impairments in physical
functions, many people use mobility aids such as a cane, crutches, a walker, a rollator or
a wheelchair (7). More and more people use mobility-related devices, with walking aids
(WAs) being the most commonly used (8-11).
Functionally, WAs increase the base of support and the amount of somatosensory
information, which help to reduce the load on the lower limbs and increase stability (7).
WAs can facilitate activities and participation of people with physical disabilities. In a
2009 systematic review (12) involving 8 studies, Salminen and colleagues concluded that
using various types of mobility aids help increase participation in activities for people
with mobility limitations. Furthermore, the results of Hammel et al.’s qualitative study
conducted among 45 people with disabilities, 10 caregivers and 10 service providers
suggest that mobility aids contribute toward a significant commitment in life and an
increase in feelings of control, freedom, worthiness and dignity (13). Authors of studies
specific to WAs have come to the same conclusion. Some walker users report going
about their activities more easily and feeling confident, independent and safe and having
more self-esteem (7, 14, 15); however, the quality of evidence of these studies limits the
confidence that can be placed in these results.
In turn, using WAs can also involve some disadvantages. Using a cane or a walker
can have destabilizing effects, interfere with the movement when recovering one’s
balance and generate major metabolic and physiological issues when moving (7).
4
Excessive use of a cane or crutch use is hypothesized to induce upper extremity nerve
entrapment injuries in poststroke patients (16). Using WAs also requires attention and
neuro-motor resources, which can compromise stability when the person is performing a
task (7). Furthermore, many people who use walkers daily claim to feel vulnerable and
dependent (14). They report having to pay more attention when they move, having
changed their self-image, feeling watched and having the impression of taking more
space with the size of the walker (14). These aspects could explain the results of Allen et
al.’s study (17) which suggests that only one third of people receiving various types of
mobility aids use them.
Thus far, some studies suggest that WAs may benefit adults with physical
disabilities whereas other studies suggest that they may interfere with personal
preferences and are not worth the additional effort required to use them. Salminen’s
review examined mobility aids in general(12) in relation to activities and participation.
However, this review dates from 2009, and no systematic review focusing specifically on
walking aid studies is available. This is an important gap given the many people who use
walking aids (9). This systematic review thus seeks to examine whether and how WAs
enable activity and participation of adults with physical disabilities.
METHODOLOGY
Search strategy
In May 2015, a search strategy was performed using electronic databases Medline
(Ovid MEDLINE® in-process and other non-indexed citations and Ovid Medline®, 1946
5
to present), Embase (1996 to present), all EBM reviews (Cochrane DSR, ACP Journal
Club, DARE, CCTR, CMR, HTA, and NHSEED), PsychInfo (to May 2015 week 2) and
CINAHL. A librarian was consulted to identify the keywords specific to each database.
The search was conducted in a hybrid fashion; in other words, by subject and keyword in
the title and summary. Given that the review by Salminen et al. (12) on mobility aids
covered the years 1996 to 2008, we targeted publications since 2008 inclusively. The
Web of Science database was searched to find relevant articles citing those previously
chosen. Finally, a manual search was conducted in the reference lists to identify other
eligible articles.
Inclusion and exclusion criteria and study selection
All types of quantitative and qualitative studies were accepted. Systematic reviews
were eliminated; however, their reference lists were reviewed to identify relevant studies
to include. Study participants had to be 18 years and older. WAs could include the cane,
crutches, the walker, the rollator but excluded experimental prototypes not commercially
available. As part of this study, the walker is described as a 3-sided tubular device with
no wheels or with 2 or 4 small wheels, while the rollator refers to a 3-sided tubular
walking aid with four wheels, a seat, back support, brakes, handles and a basket (18). The
WAs were named differently in a few articles (14, 19). Articles dealing with several
technical mobility aids, of which most were WAs, were accepted. The articles had to
include outcomes and results that were conceptually linked to one or more domains of
activity and participation as defined by the International Classification of Functioning,
Disability and Health (ICF) (20).
6
Data extraction and quality assessment
Data regarding the study design, objectives, participants, assistive device
intervention or use, outcomes and instruments, and main results were extracted by the
first author and discussed among the research team for accuracy. Data pertaining to
activity and participation domains were also extracted and summarized separately.
Quantitative studies were assigned a level of evidence based on criteria recommended by
the Center for Evidence Based Medicine (21) : 1a, systematic review of randomized
controlled trials (RCT); 1b, RCT with a narrow confidence interval; 1c, all or none of the
case series; 2a, systematic review cohort studies; 2b, cohort study/low quality RCT; 2c,
outcomes research; 3a, systematic review of a case-controlled study; 3b, case-controlled
study; 4, case series, poor cohort case-controlled study; and 5, expert opinion. Qualitative
studies were assigned a level of evidence based on Kearney’s criteria (18) with the levels
as follows: I, findings restricted by a priori framework; II, descriptive categories; III,
shared pathway or meaning; IV, depiction of experiential variation; and V, dense
explanatory description.
Two evaluators evaluated the quality of each study independently. Agreement on
quality level was reached by consensus and a third person was involved in one case of
disagreement. The Critical Appraisal Skills Programme (CASP) checklists were used
(22). Quantitative studies were rated with the CASP cohort study checklist because it was
the most appropriate for our study pool. This checklist has 12 items, including two
questions split into two parts, for a total of 14 questions to answer. Items 7 (What are the
7
results?), 8 (How precise are the results?) and 12 (What are the implications for practice?)
were not recorded as they cannot be responded by Yes, No or Can’t Tell. Also, item 6
(and its two questions) on the follow-up was eliminated because it did not apply to our
studies. Items were scored Yes, No or Can’t Tell and a point was given for each question
to which evaluators answered Yes. The maximum score was therefore out of 9. Specific
score ranges were assigned the following quality designations: Excellent (9), Good (6-8),
Fair (3-5) and Poor (1-2). Qualitative studies were rated similarly with the CASP
qualitative checklist (22) that includes 10 questions. The last question about the research
value was slightly reworded so that all questions could be answered by Yes, No or Can’t
Tell. Each question included sub-questions allowing evaluators to refine/specify their
answer. We gave one point for each question to which participants answered Yes when
most sub-questions received an affirmative response. As proposed by Mortenson et al.
(23), score ranges were assigned the following quality designations: Excellent (9-10),
Good (6-8), Fair (3-5) and Poor (1-2).
RESULTS
Study characteristics and methodological quality
The search generated 1317 articles after eliminating duplicates. From the titles
and abstracts, the first author identified 60 articles that met the inclusion/exclusion
criteria. Comprehensive reading of these articles further reduced their number. Doubtful
cases were read and discussed by three members of the research team and resolved
through consensus. At this point of the process, nine articles corresponded to the
inclusion/exclusion criteria (see Figure 1). A search in Web of Science yielded four more
8
articles for a total of 13 articles. No other articles were found as part of the manual
search.
The studies included are described in Table 1 and data specific to activities and
participation are presented in Table 2. Most studies incorporated various categories of
WAs (24-30), four articles targeted rollators (14, 19, 31, 32) and two studies looked at
different types of canes (33, 34). Study samples were small. Only four articles included
samples with more than 100 participants (24, 28, 29, 32). Two articles targeted a
population having suffered a stroke (33, 34) and two others targeted people who had
suffered a spinal cord injury (24, 28). The other studies did not target people with a
specific diagnosis. In most articles reviewed, participants were 65 years and older. Only
two articles had participants whose mean age was lower than 65 (28, 34), and the lowest
mean age documented was 46.2 years old (28). The articles were produced in various
parts of the world. In total, three articles came from North America (19, 24, 27), seven
studies from Europe (14, 25, 26, 30-33), two from Asia (28, 29) and one from Africa
(34).
From the 13 studies, seven used quantitative methods, (24, 28, 29, 31-34), five
used qualitative methods (14, 25-27, 30) and one article used mixed methods (19). As
noted in Table 2, most quantitative studies provided a relatively low level of evidence (2c
and lower). Qualitative studies were better quality and provided a level of evidence of III
(14, 25, 26, 30) and IV (13). The study with mixed methods (19) obtained a level of IV
for the quantitative section and II for the qualitative section. The results of the
methodological quality assessment are shown in Table 2. The quality of the quantitative
studies varied considerably, ranging from Fair to Excellent on the CASP checklist. The
9
quality of the qualitative studies was relatively better than the quantitative ones, with
Good and Excellent ratings.
Summary of activity and participation domains influenced by WAs
As shown in Table 2, ICF activity and participation domains discussed in the
studies include mobility (14, 19, 24, 26, 28, 29, 31, 33), self-care (24-26), domestic life
(25-27, 31, 32), community, social and civic life (25, 26, 31), interpersonal interactions
and relationships (14, 27, 32) and major life areas (32). Two studies examined activity
and participation domains as a whole (19, 34). Specific results pertaining to mobility will
be presented first, followed by all other domains.
Walking aids to enable mobility
Results in this section are organized according to the types of assistive devices
studied. Four studies mainly targeting rollators (14, 19, 26, 31) reported associations with
mobility. Rollators allow people to walk longer and more frequently (14, 19, 31) and to
go outside (26, 31). Having a seat on the device gives people the chance to rest whenever
they need to (14, 26).
Canes were found to enable mobility. Allet et al. (33) looked at three different
types of canes among participants having suffered a first stroke and not able to walk more
than 5 metres with no aid. With a cane, participants travelled a mean distance of 100
metres consecutively in 6 minutes (33). From the three types of canes studied, the single
cane was the most appreciated and the one linked to the greatest walking distance.
10
Three studies (24, 28, 29) assessed mobility in relation to various walking aid
categories. The first two involved samples of participants with a spinal cord injury.
Participants who used canes or crutches reported being better able to move within the
community and to climb stairs than those who used walkers (24). Walking distance and
speed were greater with a cane than a walker, but remained lower than the minimum
values required to be considered functional within the community (28). Another study
(29) looked at the same three types of WAs, but with elderly people with no specific
diagnosis. The results suggest that their use is positively associated with functional
mobility as measured by the Rivermead Mobility Index and Physical Mobility Scale (29);
however, it is important to note that this study was rated as fair methodologically, namely
because of concerns with its external validity.
Walking aids to enable other domains of activity and participation
Six studies reported how providing rollators to individuals with no specific
diagnosis (14, 19, 25, 26, 31, 32) contributes to participants’ activities and participation.
Somewhat negative outcomes were identified in three studies, based on interview data
(19, 25, 26). The results showed that the physical characteristics of the rollator, such as its
weight, can interfere with certain activities such as using public transportation or going to
places that have stairs (19, 25, 26, 30). In turn, four studies reported positive impacts (25,
26, 31, 32). The rollator makes going out for leisure, to shop or to socialize easier and
more frequent (25, 30-32). It helps people to participate more frequently in cultural
events (31). Furthermore, users claim to be able to talk to another person while walking,
which helps them to maintain social relationships (26). The rollator makes it easier to
11
complete household tasks such as carrying grocery bags, cooking and getting the mail
(19, 25, 26, 30).
The study involving canes (34) concluded that following a stroke, people who use
WAs participate to a lesser extent than those not using WAs, as measured with the Craig
Handicap Assessment Reporting Technique.
Finally, six studies involving several categories of WAs provided relevant
information on barriers and facilitators to activities and participation. Several negative
points emerged. Physical environment challenges were emphasized in five studies, such
as inability to access public transportation (25) or family members’ homes (35) due to
architectural barriers, or difficulty manoeuvring in crowded public places (26) or even at
home (30) . One study mentioned that walking aid users must plan their travels before
leaving to make sure there are no obstacles (25). The poor aesthetics of WAs and the
stigma that can be linked to using them are reported in two studies (14, 27). For these
reasons certain users prefer staying home rather than going out and being seen with this
sort of device (27). On the other hand, other positive aspects were unanimous among the
reviewed studies. The authors agreed that WAs help develop a feeling of safety and
independence on a daily basis among people with physical disabilities (14, 19, 25-27, 32).
In one study, participants reported that their WAs are part of their lives and that they use
them everywhere, even in the bathroom (26). This positive-negative duality of
perceptions from users toward WAs is clearly indicated in the studies conducted by
Brannstrom (14) and Resnik (27) who found contrasting themes such as confidence and
independence versus feelings of vulnerability and inferiority. Moreover, two qualitative
studies examining the temporal aspect of walking aid use (25, 26) converged regarding
12
the perceived impacts of WAs on activities and participation evolving with time and
becoming more positive among experienced users. However, in one study (30)
participants abandoned their WAs over time as their physical condition evolved and
environmental barriers such as stairs and restricted space became too challenging.
DISCUSSION
To our knowledge, this is the first systematic review exploring how WAs enable
activity and participation among adults with physical disabilities. Our search strategy
resulted in 13 articles that supplied generally low and moderate levels of evidence
regarding the benefits of WAs. Indeed, the quantitative articles reviewed were mainly
observational studies with small samples. These studies included some useful information
but were not sufficient to allow formulation of conclusions about the impact of WAs on
activity and participation. As for the qualitative studies, they contained valuable
information on the lived experiences of people using these types of devices. Together, the
studies contribute to our understanding of how using canes, crutches, walkers or rollators
can contribute to mobility and other domains of participation.
There is evidence of factors reducing the potential benefits of WAs on activity and
participation. It was found that physical characteristics such as the weight of the device in
interaction with the physical environment can make it harder to complete certain tasks
(19, 25, 26, 30). For instance, one study reported that these interactions require greater
planning of activities to anticipate and avoid obstacles as much as possible (25). Several
studies also showed people’s reluctance to use WAs (14, 25-27). This aspect represents
13
an obstacle to participation when the person decides not to take part in certain activities to
avoid being seen in public with the device. Social stigma related to disability can feed
people’s refusal to use these aids. These results are in keeping with those of Hedberg-
Kristensson et al. who mention that people’s opinion and attitudes influence the level of
acceptance of mobility aids (36). From a service provider’s perspective, it is essential to
explore and consider the person’s attitude toward the walking aid and support the person
throughout the acceptance process. More broadly, efforts should also be directed towards
the social environment to reduce the stigma associated with using WAs.
Despite these obstacles, positive outcomes were identified in the reviewed studies
and mainly emerge when people accept their WA and integrate it into their daily lives.
More specifically, numerous studies acknowledged the facilitating effects of WAs on
mobility, to ease travels in the community and allow users to travel greater distances (14,
19, 29-31). Specifically, the rollator was identified as being appreciated and offering
users the chance to take breaks during their travels. It was also established that the cane
and crutches are the WAs that allow users to travel the greatest distance (24, 28). These
conclusions are, however, not very surprising given that people using a cane or crutches
are usually not as physically disabled as those using a walker or rollator. It must be noted
that controlling for the confounding influence of physical limitations on participation
remains a challenge in studies examining walking aids.
Walking aids can affect participation in multiple ICF domains such as mobility,
self-care, domestic life, community, social and civic life, interpersonal interactions and
relationships. Studies used a mix of objective measures such as walking speed and
distance, as well as self-report questionnaires and narrative content. The number and
14
quality of studies using objective vs. subjective measures was not sufficient to distinguish
which types of measures produce the strongest association with WAs. Mobility was the
most frequently studied domain of participation, which was predictable since it is directly
related to the function for which WAs are intended (37). Mobility may also be considered
as a gateway for other domains of participation and broader health-related aspects of
well-being, such as satisfaction and quality of life. As suggested by Jutai et al. (37) in
their taxonomy of assistive technology device outcomes, we expect the effects of WAs to
be cumulative. Gains in mobility from the use of WAs can, in turn, cause changes in
other domains of activity and participation, such as domestic activities and interpersonal
interactions and relationships, which may eventually contribute to increased quality of
life.
The studies examined as part of this review mainly address the cane, the rollator
or a mix of devices, and do not put as much emphasis on crutches and the walker
individually. As a result, it is hard to draw conclusions applicable to all WAs about
whether and how they enable activity and participation. To advance scientific knowledge
regarding WAs for people with physical disabilities, studies that use a prospective design
and better-defined user groups in terms of categories of WAs, age, and diagnosis are
needed. Furthermore, to help confront the negative impacts of WAs that mainly appear
when people have not yet accepted the device, studies on this acceptance process would
be relevant to better support inexperienced users and develop a more positive general
public image of WAs.
Our review has some limitations. First, one individual identified the relevant
studies. Uncertain papers were discussed among the team, which compensated for not
15
having two independent people performing the search. Second, we did not contact the
original authors for possible additional articles. As a result, we may have omitted
otherwise eligible studies. Finally, although a systematic approach was used for data
extraction, the classification of individual study results into ICF activity and participation
domains may have involved some elements of subjectivity.
CONCLUSION
Although more advanced and specific studies are required to confirm their
effectiveness, the current data suggest that WAs enable activity and participation for
people with physical disabilities, as long as users are able to overcome certain obstacles
to integrate WAs into their daily lives.

Cross-over study 1) Examine the effects of 3 different canes on walking capacity and temporo-spatial gait parameters 2) Evaluate patients’ satisfaction with each type of cane at an early stage of gait rehabilitation
N= 25, % male NR, mean age = 67.6 yearsDx: First stroke (mean time poststroke = 42 days)Main selection criteria: early stage of gait rehabilitation, unable to walk more than 5 m alone without walking aid
Subjects tested over 3 consecutive days, each day with another randomly assigned walking aid: Nordic stick, 4-point cane and single cane with ergonomic handgrip
- Temporo-spatial gait parameters: GAITRite- Walking capacity: 6-minute walk test- Subjective benefit: scale from 0 to 10
The greatest walking distance was achieved with the simple cane (mean 115.48 m) followed by the 4-point cane (mean 101.40 m). Gait velocity and step time symmetry were better with the single cane than with the 4-point cane (mean velocity 29.42 cm/s vs. 25.84 cm/s, mean step time difference 0.37s vs. 0.56s). Participants preferred the single cane (subjective rating 7.44 vs. 6.96 for 4-point cane and 4.52 for Nordic stick).

Comprehensive questionnaire to describe participants’ health and functional profiles, semi-structured interview and observation of an activity in which the mobility device was used.
Mobility device use impacts activities and life over time. Device use increased with age. Mobility devices were important for the men’s social life but the physical environment interfered with their use. Users reported always having to plan their activities in advance and anticipate solutions to problems that may occur.

Mobility device use increases and develops toward the use of more supportive devices over time. Mobility devices are described as something whose use you have to accept, but also as a constant reminder of your limitations. Strategies and adaptive behaviours are developed over the years when striving to maintain participation. With time, mobility devices were perceived as necessary and mostly positive, and influenced

Qualitative study (focus groups)Explore attitudes toward mobility device use among elderly persons by race and ethnicity
N= 61, male 15%, mean age NRDx: NRMain selection criteria: age ≥ 60 years and spoke English or Spanish
Respondents included 32 non-device users and 29 mobility device users: cane (n= 21), walker (n= 10), wheelchair (n= 4), scooter (n= 2), multiple devices (n= 8)
Attitudes toward mobility devices: semi-structured interview guide
For all ethnic groups, positive attitudes supporting mobility aid use related primarily to perceived benefits in maintaining independence and control over activities; however, participants felt that mobility aid use was stigmatizing. Participants had a more positive attitude toward fashionable and sporty devices compared to those that could be linked to greater disability.

Overall, rollator users were more satisfied than wheelchair users (p <0.001) for both the device and prescribing process. Rollator users more often reported a positive influence of the device on the “possibility to be mobile” (p ≤ 0.05), “feeling of safety/security” (p ≤0.001), “feeling of independence” and “self-esteem” (p ≤ 0.05). Wheelchair users more often reported a positive influence of the device on the “possibility to work” (p ≤ 0.05) and “possibility to lead an active leisure life” (p ≤ 0.01).

Quantitative results varied between participants; no trends were observed. Qualitatively, participants reported improved balance and safety with the rollator but not all of them integrated it into their daily lives. Stairs and lack of space were the two most common elements of the built environment that made using the rollator challenging. Participants viewed the rollator as a sign of dependency and a “visual declaration of their physical and functional decline”.

progressed towards other WAs as their functional capacities declined. Initially, WAs helped them maintain their daily routines inside and outside the home. However, over time environmental barriers such as stairs and lack of space, combined with participants’ declining health, rendered the use of WAs too challenging and participants abandoned them. They turned to other ways of compensating their difficulties, such as asking for help or remaining indoors.

It was found that the use of a rollator helped people take walks more often, participate in cultural or sporting events more often and go outdoors for hobbies or sports more frequently. Also, in one group it became easier to walk, go to the pharmacy, post office and library, shop and visit friends and family.

people to walk longer as they could sit and rest at any time. It also allowed users to be with others as they could have a conversation while walking. Overall, using a rollator allowed people to remain active.

Mobility In this study, walking 1,000 ft was identified as a required distance for community ambulation. People using a cane or crutches were most likely to be able to walk this distance and climb a flight of stairs. People using personal assistance or a walker were least likely to climb stairs or walk 1,000 ft.

Mobility, Self-care, Domestic life, Community, social and civic life
Participants used both the cane and rollator. The men felt limited and housebound because they had to plan every scenario and anticipate problems that might occur when they went out with their WA; however, WAs were considered important in order not to be excluded from social life. Specifically, the rollator was seen as practical as it enabled men to transport things indoors and bring home groceries or sit and rest when walking outdoors. Although these WAs required new habits and
30
planning, findings showed that they supported independence and enabled men to perform activities in everyday life and participate in social life. Overall, WA use enhanced active aging.

Mobility, Domestic life, Interpersonal interactions and relationships
Many attitudes were expressed toward mobility aids. First, users acknowledged that mobility aids could help them be independent. Nonetheless, some participants still preferred personal assistance because it is less noticeable and younger looking. Secondly, users felt stigmatized and ashamed of needing help. Some reported that they would rather stay home than go out and be seen using a device. Thirdly, some participants reported that using a mobility device could make it difficult or impossible to perform ordinary tasks like carrying objects.

One woman said that her ability to participate in activities improved with the rollator because without it, she would not be able to access certain parts of her retirement home; however, using a rollator could negatively affect participation. A man reported that he was limited in his daughter’s home and that the rollator affected his ability to use public transportation.

WAs initially helped participants maintain their daily routines, do some household work and perform outdoor activities such as going for a walk, shopping and attending public places. However, over time WAs were abandoned as the participants’ physical condition evolved and environmental barriers such as stairs and restricted space became too challenging.
