Document Summary
When studying pathological gait identify primary impairment and compensatory strategies. Treat primary impairment to reduce compensatory strategies. Antalgic gait- avoiding pain by taking off the weight from the stance foot. Decreased stance time on injured side, decreased swing time in opposite foot. High steppage gait (equine)- foot drop with increased hip and knee flexion during the swing phase of gait in order to clear ground. Causes: weak ankle dorsiflexors, tight plantar flexors. Spasticity- increase in muscle tone but if you stretch a spastic muscle, resistance increases. Rigidity- increase in muscle tone but if you stretch a rigid muscle, same resistance. Vaulting- excessive ankle plantarflexion during stance phase. Cause: patient can"t shorten the cl leg. Allows ground clearance of cl leg if you lengthen the stance leg. Example patient populations: unilateral lower limb amputees (prosthetic is too long), stroke, sci. Knee hyperextension- hyperextension of the knee in the stance phase. Causes: weak quadriceps or limited ankle df.
