What distinguishes a rehabilitation aid from an ambulation air?

Its use is generally restricted to the clinic under supervision

List three specific design requirements that relate to the need for ambulation aids to be asy to use

lightweight, have easy to operate mechnisms, a minimum numver of fasteners
What benefits, other than those concerned with body support, can a walking stick offer a user

Psychological reassurance and alerts others

What type of handgrip is generally most suitable for long term, demanding use and why?

Countered (ergonimic) handgrips are generally most suitable for long term, demanding use because they helo to distribute the loads on the hands more evenly

What device can be used to prevent a walking stick from slipping on ice?

Ice spike

How are the components of folding walking stick kept togehter when folded?

Elastic cord or spring
What is it about most tipod and quadripod sticks that makes them suitable for unilateral use only?

The more lateral spread of the points

The supply and manufacture of tipod and quadripod sticks are not adversely affected by their unilateral natur. Why is this?

Most tripod and quadripod sticks can be switched between left and right using the height adjustment mechanism.

What add-on is particularly useful when a user needs to let go of the handgrip of the single point stick where there are no objects nearby?

A wrist strap

What is different about the height adjustment mechanism of axillary crutches compared to other crutches?

Acillary crutches have bolts and wingnuts rather than spring loaded push bottuns for adjusting their height.
What is the advantage of a cloased cuff?

Allows a user to let go of the handle without the crutch falling.

List two other names for forearm trough crutsches.

Gutter crutches; platform crutches

What is different about a rocker-bottom crutch compared to a standard axillary crutch?

Has a curved base with a rubber grip rather than a single point with a ferrule

The Canadian crutch is a hyprid of which two types of crutch?

A hybrid of the elbow and axillary crutches
What are fitted to all the ground contact points of all non-wheeled walking frames?

Ferrules

What would be the advantage of a reciprocal frame over a pulpit frame for a particularly unstable user?

The frame is always in contact with the ground when walking

What is the angle between the two sides of a triangular non wheeled walking frame?

60°; 90°

What are the relative advantages and disadvantages of solid and pneumatic tyres?

Solid tyres are effectively maintenance free and cheaper than pneumatic tyres. Pneumatic tyres are easier to negotiate over uneven ground.
What type of non-wheeled walking frame do standard rollators resemble?

Pulpit frames.

List three types of brakes fitted to wheeled walking frames.

Cable, spring-load, kick

What property of springs does one type of brake mechanism employ to adjust the load required to activate the brake?

The deformation of the sping is directly proportional to the applied load

What are the problems with drop bild folding mechanisms?

The difficulties removing the bold to fold the frame and aligning the components when erecting the frame

Is a frame with higher handles more or less stable than one with lower handles? Why?

With higher handless= less stable. Because a smaller horizontal force is required to tip it over since the force will have a greater moment arm.
