Prosthesis and Gait
NPTE: Gait Deviations - Prosthetic and Amputee Causes (scorebuilder 2008)
Gait Deviation | Prosthetic Cause | Amputee Cause |
---|---|---|
Abducted Gait | • Prosthesis may be too long • High medial wall • Poorly shaped lateral wall • Prosthesis positioned in abduction • Inadequate suspension • Excessive knee friction | • Abduction contracture • Improper training • Adductor roll • Weak hip flexors and adductors • Pain over lateral residual limb |
Circumducted Gait | • Prosthesis may be too long • Too much friction in the knee • Socket is too small • Excessive plantar flexion of prosthetic foot | • Abduction contracture • Improper training • Weak hip flexors • Lacks confidence to flex the knee • Painful anterior distal stump • Inability to initiate prosthetic knee flexion |
Excessive knee flexion during stance | • Socket set forward in relation to foot • Foot sett in excessive dorsiflexion • Stiff heel • Prosthesis is too long | • Knee flexion contracture • Hip flexion contracture • Pain anteriorly in residual limb • Decrease in quadriceps strength • Poor balance |
Vaulting | • Prosthesis may be too long • Inadequate socket suspension • Excessive alignment stability • Foot in excess plantar flexion | • Residual limb discomfort • Improper training • Fear of stubbing toe • Short residual limb • Painful hip/residual limb |
Rotation of Forefoot at Heel Strike | • Excessive toe-out built in • Loose fitting socket • Inadequate suspension • Rigid SACH heel cushion | • Poor muscle control • Improper training • Weak medial rotators • Short residual limb |
Forward trunk flexion | • Socket is too big • Poor suspension • Knee instability | • Hip flexion contracture • Weak hip extensors • Pain with ischial weight bearing • Inability to initiate prosthetic knee flexion |
Medial or Lateral whip | • Excessive rotation of the knee • Tight fitting socket • Valgus in the prosthetic knee • Improper alignment of toe break | • Improper training • Weak hip rotators • Knee instability |
Lateral Bending | • Prosthesis may be too short • Improperly shaped lateral wall • High Medial Wall • Prosthesis aligned in abduction | • Poor balance • Abduction contracture • Improper training • Short residual limb • Weak hip abductors on prosthetic side • Hypersensitive and painful residual limb |
