Abstract

|
|
Purpose: The purpose of this study was to compare the effects of force of ipsilateral versus contralateral cane usage on knee moments in healthy young adults.
Methods: A convenience sample of 10 subjects volunteered for this study. Subjects walked over a force plate under three different conditions; unaided and ipsilateral cane and contralateral cane. Analysis of data on moment of the knee joint and ground reaction force was performed using the OrthoTrak program.
Results: Flexion moment of the knee was decreased with the contralateral cane, but increased with the ipsilateral cane compared with normal gait. Extension moment of the knee was decreased with the contralateral cane compared with normal gait(p<0.05) and it was showed a greater decrease with the contralateral cane than with the ipsilateral cane gait(p=0.00). Valgus moment of the knee joint was increased with the ipsilateral cane but decreased with the contralateral cane. Vertical ground peak force was decreased with the ipsilateral cane compared with normal gait (p<0.05).
Conclusion: The following conclusions were drawn from our data. Contralateral cane gait is more efficacious for persons with weakness of knee extensors, however, for a patient with varus deformity, the cane should be used in the ipsilateral hand.
