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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '45 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 45-85 years old\n* Able to walk 30 feet without postural sway and able to stand unaided\n* Knee pain on movement with a WOMAC pain subscale of \\>35mm\n* Documented osteoarthritis based on clinical and radiographic criteria\n* Body Mass Index (BMI) \\> 25.0 - 29.9\n* Ability to understand verbal and written instructions\n* Ability to give informed consent determined by assessment of cognitive status\n\nExclusion Criteria:\n\n* Concurrent medical/arthritic disease that could confound or interfere with evaluation of pain or efficacy.
