Musculoskeletal
Amputation and Prosthetics: Gait Deviations
Question | Answer |
---|---|
Lateral Bending (Prosthetic causes) | Prosthesis too short; improperly shaped lateral wall; high medial wall; prosthesis aligned in abduction |
Lateral Bending (Amputee causes) | Poor balance; abduction contracture; improper training; short residual limb; weak hip abductors on prosthetic side; hypersensitive and painful residual limb |
Abducted gait (Prosthetic causes) | Prosthesis too long; high medial wall; poorly shaped lateral wall; prosthesis positioned in abduction; inadequate suspension, excessive knee friction |
Abducted gait (Amputee causes) | Abduction contracture; improper training; adductor roll; weak hip flexors and adductors; pain over lateral residual limb |
Circumducted gait (Prosthetic causes) | Prosthesis too long; excessive friction in knee; socket too small, excessive plantar flexion of prosthetic foot |
Circumducted gait (Amputee causes) | Abduction contracture; improper training; weak hip flexors; lacks confidence to flex the knee; painful anterior distal residual limb; inability to initiate prosthetic knee flexion |
Excessive knee flexion during stance (Prosthetic causes) | Socket set forward in relation to foot; foot set in excessive dorsiflexion; stiff heel; prosthesis too long |
Excessive knee flexion during stance (Amputee causes) | Knee flexion contracture; hip flexion contracture; pain anteriorly in residual limb; decrease in quad strength; poor balance |
Vaulting (Prosthetic causes) | Prosthesis too long; inadequate socket suspension; excessive alignment stability; foot in excessive plantar flexion |
Vaulting (Amputee causes) | Residual limb discomfort; improper training; fear of stubbing toe; short residual limb, painful hip/residual limb |
Rotation of Forefoot at Heel Strike (Prosthetic causes) | Excessive toe-out built in; loose fitting socket; inadequate suspension; rigid SACH heel cushion |
Rotation of Forefoot at Heel Strike (Amputee causes) | Poor muscle control; improper training; weak medial rotators; short residual limb |
Forward Trunk Flexion (Prosthetic causes) | Socket too big; poor suspension; knee instability |
Forward Trunk Flexion (Amputee causes) | Hip flexion contracture; weak hip extensors; pain w/ ischial weight bearing; inability to initiate prosthetic knee flexion |
Medial or Lateral Whip (Prosthetic causes) | Excessive rotation of the knee; tight socket fit; valgus in the prosthetic knee; improper alignment of toe break |
Medial or Lateral Whip (Amputee causes) | Improper training; weak hip rotators; knee instability |
