Walking Aids in the Management of Knee Osteoarthritis
The purpose of this study is to assess whether the single point cane will relieve pain and disability in overweight or obese people with knee OA through altered joint biomechanics and what factors influence acceptance of cane use.

- Peak Vertical Force on Affected Limb [ Time Frame: Baseline and end of first intervention period (2 months) ] [ Designated as safety issue: No ]An in-shoe dynamic, pressure distribution system (Pedar-X System, Novel Electronics, Inc., St. Paul, MN) was utilized to measure the vertical ground reaction force at the baseline visit and at the end of the first intervention period (two months) gait evaluations for both the control arm and cane user arm. The control arm was not given a cane to use at home during the two month intervention period. Peak vertical force on the affected limb was measured in the laboratory setting when both control group and cane user group walked with and without a cane at baseline and at the end of the first intervention period (2 months).

Active Comparator: Single point cane
People with knee osteoarthritis underwent gait analysis with a cane
Device: Single point cane
Participants with symptomatic knee osteoarthritis will undergo gait evaluation with and without a single point cane.
Other Name: Guardian offset handled cane with sure grip
Placebo Comparator: No cane
Patients with knee osteoarthritis undergo gait analysis without a cane
Knee OA is an important cause of disability and falls in overweight or obese individuals and limits their attempts at exercise and subsequent weight loss. Walking aids such as canes have been recommended in the management of knee OA in order to decrease pain by reducing loading across the knee and to increase physical activity. Little information is available regarding the impact of walking aids on psychosocial function and quality of life in individuals with limited mobility. No randomized controlled trials have studied the efficacy of walking aids on quality of life, pain, and function in overweight or obese individuals with symptomatic knee OA (5,6). The proposed research will evaluate the effects of walking aids in knee OA by testing the following hypothesis that the use of a single-point cane ipsilateral and contralateral to the affected limb will decrease pain from knee OA by altering gait biomechanics and will improve walking function and quality of life in overweight or obese individuals with symptomatic knee OA.
