Ergonomics: Saving your Back and ArmsChapter 4.1.5

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.

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.

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

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.

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.

Tactile Positions, cont.KEY POINTS• Take time to get comfortable• Get close• Be on the same level• Have support for your arms and back

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.

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.

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.

GUIDING

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.

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.

Pause – Put Things Down

TIME

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.

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!

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.

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.

CLOTHES

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

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.

ShoesYour shoes should be comfortable, with flat, non-slip soles for good balance. Sandals are often attractive and comfortable, however they do not protect your feet from being bumped or accidentally stepped on.

AND…

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.

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.

Conclusion, cont.• Don’t try to do too much in one outing.

Rushing creates stress.• Plan ahead so you will have the right

clothes.
