What are the benefits of using an early walking aid?

Provides a means of assesing the patient's potential to use a prosthesis Improves exercise tolerance Improves balance reactions Strangthens muscles used in walking Promotes wound healing as it aids circulation Assists in the reduction of residual limb oedema which can lead to earlier casting for a prosthesis Boosts the patient's psychological well-being

How does gait re-education commence?

Between parallel bars

List five aspects of the role of the occupational therapist in rehabilitation of the amputee

Wheelchair assesment and training; Routine activities of daily living assessment and training; Training using graded activities; Assessment of environmental constraints and requirements; Community liaison and follow up

Briefly describe the different ways of accessing a toilet recommended for unilateral and bilateral amputees

Unilatera: conventional with back to cistern. Bilateral: "walks" forward on stumps facing cistern may manage sideways transfer if space allows.

List the activities of daily living that are part of the rehabilitation process

Access to and from the WC, bed, chairs, bath and shower Dressing Kitchen activites Leisure Work

What types of fabrics are suitable for amputees?

Lightweight, breathable and absorbent

What special precautions are necessary before an amputee returns to work?

Occupational therapist to visit and to advise on minimising obstacles.

List the objectives of graded activities

To increase balance, tolerance and weight transference; To increase shoulder and elbow movement and lateral trunk rotation; To develop bilateral hand/eye co-ordination; To develop upper body strength; To maintain or regain interactive group skills

Give three examples of graded activities

Woodwork; gardening; stool seating; kitchen activities; darts & snooker; using a printing press or sewing machine

How are environmental constraints and requirements assessed?

By domiciliary visits by the occupational therapist, patient and community occupational therapist

What role do community services play in the rehabilitation of the amputee?

Ensuring a contract point is in place at time of discharge. To organise home adaption prior to discharge

Patellar Tendon Bearing (PTB) prosthesis

For lower limb amputee with trans-tibial amputation the PTB is normaly prescribed. This design permits full weight bearing upon the socket, is often self suspending and is reasonably lightweight and cosmetic in appearance.

What is a limb priosthesis?

Externally applied device used to replace wholly, or part, an absent or deficient limb segment

What are the prosthetic requirements for an elderly trans-femoral amputee?

Comfortable waist belt and socket. A mechanical knee that will lock to provide stability, altough it requires more energy to walk than with a flexible knee, and early mobilisation.

What prehensile devices are available for the upper limb amputee?

Hook, hands, terminal devices such as tools, eating utensils etc.

How are these prehensile devices controlled?

Cord operated myoelectric devices, hybrid devices, electrical devices.

Why is social reintegration important?

To reduce feelings of isolation and handicap

When is a patient discharged?

When a prosthesis has been fitted, and the patient's home has been assessed

Why should a patient remain in contact with the limb fitting centre after discharge?

For maintanance and provision of prosthesis, for stump and prosthetic review and for assessment and monitoring of how a patient is managing at home.

Objective requirement for lower limb prosthetic

Comfort; Function; Cosmesis

Static cosmesis

shaoe and color also feel or texture of the surface of the prosthesis

Dynamic cosmesis

The principal objective to conceal the disability of the patient's gait-pattern.

Prosthetic components

Interface components; functional components; alignment components; structural components; cosmetic components

If independent mobility os the over-riding objective of lower limb prosthetic replacement, what are the three specific objectives which contribute to the attainment of this?

Comfort; Function; Cosmesis

List the five catagories of prosthetic component defined by the International Standard Organisation

Interface components; functional components; alignment components; structural components; cosmetic components

Interface components of a prosthesis

socket and the suspensory components

Fthree types of force transmission

support; stabilisation; suspension

Anatomical suspension

Anchoring the socket to the underlying anatomy and this may require the socket shape to be adjustable by means of removable sections or splits to permit doffing and donning. Often in knee disarticulation

Pressure differential suspension

Creating a socket with a closed end which will resist removal by virtue of the pressure diffential which would result from such action. More common in shaft amputations. Adhesion between the stump and the inner socket wall may contribute additionally to suspension.

List the three types of force transmission that interfae components must permit

Support; stabilisation; suspension

What is the principal means of support in a socket for a pationt with a trans-femoral amutation and a knee disarticulation patient?

Proximal support Distal support

Interface material to transmit the forces to the stump

Silicon; Urethane or Polymer gel

What will be the effect of moving the foot of a trans-tibial prosthesis laterally upon (a) the magnitude of the stabilising forces in the coronal plane (b) the appearance of the patient’s gait?

a= Reduced magnitude of forces b= Wide based gait

Functional components

Substitute for some of the dynamic and sensory attributes of the normal limb. The need to bear the weight and to allow controll movement.

Functional components of lower limb

Ankle-foot devices; knee units; hip units

What are the two primary requirements of all lower limb prosthetic functional components?

To bear the weight of the amputee and to allow controlled movement of the joints

Uniaxial ankle-foot

simplest articulated ankle foot design. The normal ankle joint motion is replaced with a simple hinge joint allowing rotation in the sagittal plane only and control is achieved by rubber bumpers. The shock loads at heel contact are reduced by allowing some plantarflexion resisted by the plantarflexion bumper. The movement at roll over is allowed by movement of the joint. Dorsiflexion is resisted during push off by the dorsiflexion stop.

Multiaxial ankle-feet

more complex mechanical joint which, as well as permitting dorsiflesxion/plantarflexion, allows for some inversion/eversion and interal/external rotation.

Non-articulated ankle-foot

can be divided into those with a rigid ankle and those with a flexible ankle.

Flexible ankle

Ankle mechanism is made of a flexible material which deforms to replicate ankle movement
