Purpose: The purpose of this study was to compare the efficacy between Normal Cane and Shock Absorbing Cane on energy expenditure and pain in persons with Knee Osteoarthritis. Method: An Experimental study was carried out on 60 symptomatic persons with knee osteoarthritis. Two different canes were used. Resting and walking heart rate were measured with a portable pulse Oximeter. Pain was measured by using Visual Analogue Scale (VAS) with both the canes. Gait energy cost was estimated using the Physiological Cost Index (PCI) and results of PCI and VAS were compared. Result: It was found that with the application of Shock absorbing cane, energy expenditure and pain both reduced significantly as compared with normal cane. Conclusion: The subjects walked farther distance using Shock Absorbing Cane.
