Prosthetic training and gait training for a lower-limb amputee

Rehabilitation is individualized by amputation level, wound healing, cause of amputation, strength, balance, cognition, condition of the opposite limb, and goals. It is delivered by a team that includes the surgeon/physiatrist, prosthetist, physiotherapist, occupational therapist, nurse, and psychologist.

The overall aim is safe, energy-efficient, symmetrical walking and independent prosthesis use, while protecting the residual limb and intact limb. Amputee gait has a greater metabolic cost than normal walking, particularly after more proximal amputations. Miller’s Review of Orthopaedics, p. 788.

1. Pre-prosthetic training

This begins soon after surgery, once medically appropriate.

A. Residual-limb care

Inspect the incision and skin daily for redness, blisters, abrasion, ulceration, discharge, or infection.
Maintain hygiene and appropriate skin moisturization. Avoid applying lotion immediately before donning the socket.
Control oedema and shape the residual limb using elastic bandaging, a shrinker, rigid or removable rigid dressing, according to the clinical plan.
Teach scar mobilization and desensitization after wound healing: gentle massage, tapping, rubbing with varied textures, and graded pressure.
Manage phantom limb pain and residual-limb pain. Persistent new pain, skin breakdown, socket pain, or sudden change in limb volume requires reassessment.

B. Prevention of contracture Contractures interfere with socket fitting and cause gait deviations.

Transtibial amputation: prevent knee-flexion contracture. Encourage full knee extension. Avoid prolonged sitting with a pillow under the knee.
Transfemoral amputation: prevent hip-flexion, hip-abduction, and external-rotation contracture. Avoid prolonged sitting with the hip flexed, placing a pillow under the residual thigh, or lying with the limb abducted.
Prescribe regular active and passive range-of-motion exercises and appropriate positioning, including prone lying when suitable.

C. Strengthening and conditioning Train:

Hip extensors, abductors, adductors, and rotators of the amputated side
Quadriceps and hamstrings, especially in transtibial amputation
Core, abdominal, and back extensor muscles
Intact limb strength, upper-limb strength, and cardiovascular endurance

Trunk strengthening can reduce compensatory gait deviations and back pain. Adult lower-limb amputee rehabilitation guidance also emphasizes preservation of range of motion because limitation can impair fit and walking.

D. Balance, transfers, and mobility without the prosthesis

Bed mobility, rolling, sitting balance, and sit-to-stand
Transfers between bed, chair, toilet, car, and floor recovery where appropriate
Wheelchair skills and safe use of walker, crutches, or cane
Single-limb standing balance on the intact limb
Fall-prevention education and protection of the intact foot, especially in dysvascular diabetes-related amputation

2. Prosthetic training

Prosthetic training begins when the wound is healed, residual-limb volume is reasonably stable, pain is controlled, and the patient is medically fit.

A. Prosthesis orientation and donning

Teach the patient to:

Identify components: socket, liner, suspension system, knee unit if present, pylon, and foot.
Put on and remove the prosthesis correctly.
Achieve correct seating of the residual limb within the socket.
Use socks or liners correctly and adjust sock ply for volume fluctuation.
Check suspension and alignment.
Inspect the residual limb after each period of wear.

A gradual wearing schedule is used, with frequent skin checks. Early excessive wear may cause pressure injury.

B. Standing and weight-bearing

Progress from:

Standing in parallel bars
Equal weight distribution between the intact and prosthetic limbs
Controlled lateral, forward-backward, and diagonal weight shifts
Reaching activities and trunk rotation while standing
Single-limb support on the prosthetic limb, as safely tolerated

The patient must learn to trust the prosthetic side, use sensory feedback from the residual limb-socket interface, and recognize the position of the prosthetic foot.

C. Prosthetic control

Controlled loading of the prosthetic heel at initial contact
Maintaining knee stability in stance, especially for transfemoral amputees
Controlled forward progression over the prosthetic foot
Appropriate toe loading before swing
Safe knee flexion and foot clearance during swing
Learning to recover safely from a stumble, where appropriate

For transfemoral prostheses, training particularly focuses on controlling the prosthetic knee during stance, avoiding knee buckling, and achieving adequate hip extension.

3. Gait training

Gait training should be supervised by a physiotherapist and should combine pre-gait work, feedback, progressive walking tasks, and functional practice. A clinical gait-training guideline recommends tactile, verbal, and visual feedback, with overground gait practice and, where available, treadmill training with or without body-weight support. Prosthetic gait-training recommendations

A. Initial gait training

Usually performed in parallel bars:

Establish upright posture with level pelvis and relaxed shoulders.
Practise weight transfer onto the prosthetic limb.
Step with the intact limb while maintaining prosthetic stance stability.
Step with the prosthetic limb with adequate toe clearance.
Progress from step-to gait to step-through gait.
Train equal step length, equal stance time, appropriate cadence, and arm swing.

The goal is not to force an artificial “normal” pattern. Prosthetic alignment and components should be adjusted to suit the individual’s functional gait while minimizing harmful compensations. Physical therapy management principles

B. Progression of walking aids

Progress only when balance and safety permit:

Parallel bars
Walker
Two crutches
One crutch or cane, usually on the side opposite the prosthesis when required
Independent walking

The aid is reduced only if the patient can walk without falls, excessive compensations, or unsafe knee instability.

C. Advanced gait activities

After basic level walking is safe, practise:

Starting, stopping, and turning
Changing speed and direction
Walking in narrow spaces and crowded environments
Uneven ground, grass, gravel, slopes, ramps, and curbs
Stairs
Obstacle crossing
Carrying objects, dual-task walking, and community ambulation
Getting up from the floor after a fall
Recreational, vocational, and sport-specific activities when relevant

Stairs:

Initially, use rails and a step-to pattern.
Ascend: “up with the sound limb” first.
Descend: “down with the prosthesis” first.
More advanced reciprocal stair walking depends on amputation level, knee mechanism, strength, confidence, and safety.

4. Gait assessment and correction of common deviations

Observe the patient from the front, side, and back. Compare prosthetic and intact sides for symmetry. Gait asymmetry may arise from poor fit/alignment, residual-limb volume change, pain, weakness, contracture, fear, poor balance, or established habits. The VA/DoD gait-analysis guide stresses that both prosthetic and patient-related causes must be checked.

Deviation	Common causes	Management
Reduced stance time on prosthesis	Pain, poor confidence, weak hip abductors, poor socket fit	Check skin/socket; graded weight shift; strengthen; gait feedback
Circumduction	Prosthesis too long, inadequate knee flexion, poor suspension, fear of toe catching	Check length and suspension; improve knee control; practise swing clearance
Hip hiking	Prosthesis too long or inability to flex knee during swing	Check fit/alignment; train knee flexion and pelvic control
Vaulting on intact limb	Prosthetic limb effectively too long or poor toe clearance	Correct length/alignment; improve prosthetic swing control
Excessive lateral trunk lean toward prosthesis	Weak hip abductors, pain, wide base, socket/alignment issue	Hip-abductor strengthening; correct alignment; balance training
Excessive lumbar lordosis or trunk extension	Hip-flexion contracture, weak hip extensors, inappropriate alignment	Stretch hip flexors; strengthen extensors/core; reassess alignment
Unequal step length	Fear, pain, poor weight transfer, inadequate push-off	Visual/verbal feedback, gait drills, address fit and confidence
Excessive toe-out or toe-in	Prosthetic malalignment or poor residual-limb control	Reassess alignment and donning; strengthen hip rotators

A gait deviation should not automatically be treated as a “patient error.” Socket fit, suspension, component settings, and alignment should be assessed jointly with the prosthetist.

5. Education and long-term follow-up

Teach the patient and family:

Daily residual-limb and intact-foot inspection
Warning signs: persistent redness lasting more than about 20-30 minutes after removal, blistering, ulceration, increasing pain, fever, sudden poor fit, or repeated falls
Skin hygiene, sock management, and prosthesis maintenance
Weight management, smoking cessation, diabetic foot care, and vascular risk-factor control when applicable
Use of appropriate footwear on the intact limb
Fall prevention and emergency contact plan
Need for regular prosthetic review because residual-limb volume, strength, activity level, and component needs change over time

Recent evidence also suggests that real-world prosthesis use varies markedly between individuals and is influenced by multiple personal and contextual factors, supporting goal-based, individualized rehabilitation rather than a fixed timetable (2024 systematic review, PMID 37927090).

Summary: successful lower-limb prosthetic rehabilitation follows a sequence of residual-limb preparation, prevention of contracture, strengthening and balance training, prosthetic care and controlled weight-bearing, basic gait re-education, functional community mobility, and continuing reassessment of skin, fit, alignment, and safety.
