Participants: 16 subjects, 23-59 years, divided into Group I (diabetic) and

Group II (control).

Interventions: To measure the bite force a digital dynamometer (model

IDDKkratos)waspositioned in the region of the firstmolars (left and right) and

threemeasurements were madewith an interval of twominutes between them.

Main Outcome Measures: Three measurements were made with an interval

of two minutes between them.

Results: It was found that there was statistically significant difference

between the groups (p <0.05). Patients with diabetes had lower bite force

values on both sides as compared with the control group, and this finding

was statistically significant (p <0.01).

Conclusions: These results show that diabetes influences the bite force.

This finding is clinically relevant because most diabetics experience

considerable tooth loss over time, and this should be taken into account

during the oral rehabilitation process.

Obesity Misclassification and Cardiometabolic Risk in Adults withFunctional Mobility Impairment: NHANES 2003-2006

Mark Peterson (University of Michigan), Soham Al Snih

Objectives: The purpose of this study was to estimate the degree of obesity

misclassification and cardiometabolic risk among adults with chronic

motor impairments.

Design: Cross-sectional.Setting: In-person interview and physical examination, from the combined

2003-2006 National Health and Nutrition Examination Survey

(NHANES) datasets.

Participants: Representative sample of 852 individuals, aged 20-85 years,

reporting at least one major functional limitation related to mobility or

lower body function.

Intervention: BMI, percent body fat (%BF) determined by dual energy X-

ray absorptiometry (DXA) and established markers of insulin sensitivity,

lipid profile and cardiovascular risk were analyzed.

Main Outcome Measures: Sensitivity, specificity, and receiver operating

characteristic (ROC) curves were used to evaluate the performance of BMI

as a continuous variable, as well as various specific BMI thresholds to

detect obesity defined by %BF.

Results: 41% of subjects classified as “lean” and 98% of individuals classi-

fied as “overweight” according to BMI had a %BF within the obesity range.

The BMI cutoff for obesity had excellent specificity in both men (100%) and

women (98.4%), but poor sensitivity (<55%). The optimal threshold for BMI

to detect obese %BF was 25kg$m-2 for both sexes. Each component of car-

diometabolic risk and the metabolic syndrome were robustly associated with

%BF, even after adjusting for age, gender, and sociodemographic factors.

Conclusions: Obesity misclassification and cardiometabolic risk is prev-

alent among individuals with motor impairment, and thus diagnostic

screening for obesity should be modified in mobility-impaired populations.

Key Words: Obesity, body composition, mobility impairment, abdominal

adiposity, metabolic syndrome.

The Self-Report Fecal Incontinence and Constipation Questionnaire(FICQ) in Patients with Pelvic Floor Dysfunction Seeking OutpatientRehabilitation

Ying-Chih Wang (University of Wisconsin-Milwaukee)

Objective: To perform a psychometric analysis of the Fecal Incontinence

and Constipation Questionnaire (FICQ) in patients seeking outpatient

rehabilitation services due to pelvic floor dysfunction (PFD), and to develop

an Item Response Theory (IRT)-based item bank suitable for computerized

adaptive testing (CAT) application for this patient population.

Design: Cross-sectional data analysis. We assessed a 20-item FICQ for

unidimensionality and local independence, differential item functioning

(DIF), item fit, item hierarchical structure, and test precision using IRT

partial credit model.

Setting: Outpatient rehabilitation.Participants: 644 patients (mean age 52, SD 16, min 18, max 91) being

treated for their PFD in 64 outpatient rehabilitation clinics in 20 states (USA).

Interventions: NAMain Outcome Measure(s): FICQResults: Factor analyses supported the two-factor subscales as original

defined: items related to either leakage or constipation severity. Removal

of two items improved unidimensionality and local independence. Among

remaining items, two items were suggestive of adjustment for DIF by age

group and by number of PFD comorbid conditions. Item difficulties were

suitable for patients with PFD with no ceiling or floor effect. Mean item

difficulty parameters for each subscale ranged from 38.8 to 62.3, and 28.1

to 63.3 (0 to 100 scale), respectively. Endorsed leakage items representing

highest difficulty levels were related to delay defecation, and confidence to

control bowel leakage. Endorsed constipation items representing highest

difficulty levels were related to the need to strain during a bowel move-

ment and the frequency of bowel movements.

Conclusions: Results supported its initial use for patients with PFD in

outpatient rehabilitation services.

Key Words: Rehabiliation, pelvic floor, fecal incontinence

Clinicians’ Use of the Multiple Errands Test for adults withNeurological Disorders

Emily Joan Nalder (Baycrest Hospital), Nicole Anderson,Amanda Clark, Deirdre Dawson

Objective: To investigate clinicians’ experiences adapting the Multiple

Errands Test (MET) to their worksites and determine how findings inform

their clinical practicewhen working with adults with neurological disorders.

Design: Qualitative research design.

Setting: Participants interviewed worked in inpatient, outpatient and

community based rehabilitation settings.

Participants: A purposive sample of 8 clinicians with experience using the

MET in clinical practice were recruited.

Interventions: Not applicableMain Outcome measures: The MET is an ecologically valid assessment of

how executive dysfunction impacts real-life performance. Individuals

complete required tasks (e.g., purchasing items) while adhering to set rules

(e.g., you must not speak to the examiner). In-depth semi-structured inter-

views were conducted using an interview guide to explore topics such as

organisational context, processes for adapting theMET, and use ofMETdata

in clinical practice.

Results: Preliminary analyses showed the MET to be clinically useful for

monitoring rehabilitation progress, functional capacity evaluations and

lifetime care planning. Organisational factors influenced how the METwas

used, and site specific adaptations to the assessment. Strategies employed

by individuals during MET completion were a dominant data source used

by clinicians to interpret individual performance.

Conclusions: Findings indicate observations of client behaviour and

strategy use during MET completion inform clinical decisions around

rehabilitation needs. Results will inform the development of knowledge

translation strategies (e.g., the development of a training manual for the

MET) to effectively address clinician needs across contexts.

Key Words: Executive function, task performance and analysis, profes-

sional practice, rehabilitation.
