Overview• Ergonomics is the study of efficient use
of space to save our energy and prevent injury.
• The work of SSPs is both mental and physical.
• This presentation focuses on the physical aspects of work as an SSP, and when communicating with DB people.
![Page 3: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/3.jpg)
Eyes, Ears, Arms & Backs• Listening as a DB person is more
physically straining than for a hearing person (listening to ordinary speech).
• For DB people listening auditorily causes strain for the focus it requires.
• For DB people, watching causes eye strain.
![Page 4: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/4.jpg)
Eyes, Ears, Arms & Backs, cont.• Reaching up to feel signs causes more
strain than being on the same level.• For DB people it is important to be in a
good position – to see, hear, feel.

TACTILE SIGNING
![Page 6: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/6.jpg)
Avoid Leaning• When signing tactually get close.
Notice the back strain for the people in the picture.
• At least the man on the left is supporting himself on the table.
![Page 7: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/7.jpg)

Tactile Position• Another power point describes
positions for guiding. Some of the different positions relate to ergonomics.
• For communication there are key principles or points.
![Page 9: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/9.jpg)
Tactile Positions, cont.KEY POINTS• Take time to get comfortable• Get close• Be on the same level• Have support for your arms and back
![Page 10: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/10.jpg)
DemonstrationIn the next slide, instructor Jelica Nuccio demonstrate the conversational position for communicating tactually, while SSPs gather around to watch.

Sitting• In the next two slides, the women are
seated side by side to communicate tactually.
• They are close enough to each other that they can use the backs of the chairs for support.
• They can also rest their arms in their laps when they pause, and still feel some of the body language of each other as they chat.
![Page 13: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/13.jpg)
![Page 14: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/14.jpg)
![Page 15: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/15.jpg)
Temporary Positioning• In the next two slides someone
approaches a seated friend(s) to ask a quick question. They squat down so they are both on the same level and the DB persons do not have to reach up, straining their arms.
• For longer conversations both/all will be seated or stand to save knees as well as arms and backs.
![Page 16: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/16.jpg)

Pillows, Tables, Chairs, Knees• For long meetings or week-long
conferences (here at AADB) some people like pillows.
• For long conversations, tables and the backs of chairs are good supports as well.
![Page 19: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/19.jpg)

GUIDING
![Page 21: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/21.jpg)
Shoulders & Elbows• When you can, put your arms down so
your shoulder and elbows can rest.• In the next slide the SSP rests her arms
while guiding the DB person.
![Page 22: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/22.jpg)
![Page 23: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/23.jpg)
Shoulders & Elbows, cont.• In the next picture, the SSP rests her
left arm but keeps contact with the DB person using her right arm.
• Nevertheless, the SSP’s right arm is still hanging comfortably down from her shoulder. It is only her forearm that is raised.
![Page 24: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/24.jpg)
![Page 25: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/25.jpg)
Pause – Put Things Down
![Page 26: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/26.jpg)
TIME
![Page 27: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/27.jpg)
Time & Pace• Doing good SSP work requires good
communication. • It is often worth the time to pause and
communicate clearly about the goals or agenda for the day, and to clarify as you go along.
![Page 28: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/28.jpg)
Time & Pace, cont.• Clear communication may require a
pause while you are walking.• It takes time for the DB person to
process the minimal information they get through feet and cane regarding the terrain.
• Don’t rush!
![Page 29: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/29.jpg)
Find a Quiet Place• Noise (auditory, visual, physical or
emotional) is both distracting and stressful.
• Sit or stand away from traffic so you can focus.
• Don’t stand for long in the doorway or aisle blocking others.
![Page 30: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/30.jpg)
Find a Quiet Place, cont.• Remind yourself that you are here for
the DB person; let all thoughts and worries about your own chores or worries be on hold while you shift into the DEAF-BLIND WAY and focus on the work.
![Page 31: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/31.jpg)
CLOTHES
![Page 32: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/32.jpg)
In GeneralBe sure your shoes and clothes support your work. • Baggy sleeves and some jewelry get in
the way• Your tops should be of plain, contrasting
colors
![Page 33: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/33.jpg)
In General, cont.Clothes with generous pockets and a small day-pack or purse that you can wear over your shoulder or across your chest will help free up your hands.

AND…
![Page 38: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/38.jpg)
Which side?• Many hard-of-hearing people have better
hearing in one ear than in the other. Check this out.
• The same is true for DB people listening tactually. Do they have a preference for one hand over the other?
• Being on the ‘better side’ will save strain for the DB person.
![Page 39: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/39.jpg)
Left SideIn the next slide the woman is reading the tactile map with her left hand. The SSP-guide verbally describes the map while gently guiding the blind woman’s hand to the mark.

Conclusion• SSP work is physical as well as mental.• Take time to be comfortable. Get on the
same level to communicate (both standing, etc.)
• Take the opportunity to rest your arms and back.
![Page 42: Ergonomics: Saving your Back and Arms](https://reader035.fdocuments.us/reader035/viewer/2022062302/56816695550346895dda7983/html5/thumbnails/42.jpg)
Conclusion, cont.• Don’t try to do too much in one outing.
Rushing creates stress.• Plan ahead so you will have the right
clothes.
