Current Primary Outcome Measures
 (submitted: December 9, 2014)
Neuromuscular Control [ Time Frame: 1 day ]
Neuromuscular control will be assessed through muscle co-activation index from electromyography (EMG) of the hamstrings, quadriceps and gastrocnemius. The electromechanical delay (delay between the onset of EMG and force), active proprioception and force accuracy and steadiness measure determined from submaximal isometric contractions will be used to determine neuromuscular control

Current Secondary Outcome Measures
 (submitted: December 9, 2014)
Disease Outcome [ Time Frame: 1 day ]
Joint damage scored using the Boston Leeds Osteoarthritis Knee Score (BLOKS) from 1.5T MRI along with pain and function assessed from knee injury and osteoarthritis score (KOOS) and patient reported outcomes measurement information system (PROMIS) will be used to determine disease outcome.
Original Secondary Outcome Measures Same as current
Current Other Pre-specified Outcome Measures
 (submitted: December 9, 2014)
Determinants of knee osteoarthritis [ Time Frame: 1 day ]
Muscle strength (peak force) will be assessed from maximal isometric contractions of the knee, along with passive motion and position sense proprioception as determinants of knee osteoarthritis.
Original Other Pre-specified Outcome Measures Same as current
Descriptive Information
Brief Title Neuromuscular Control in Knee Osteoarthritis
Official Title Neuromuscular Control in Knee Osteoarthritis
Brief Summary Arthritis is one of the most prevailing causes of disability with knee osteoarthritis (KOA) the most common form. The lifetime risk of developing symptomatic KOA by the age of 85 years is 44.7%, where females are at a greater risk (1.8 times) than male counter parts. KOA is the leading cause of limitations in activities of daily living such as walking and climbing stairs particularly in the elderly. This is primarily due to pain and instability of the joint resulting in buckling of knees caused by muscle weakness, joint stiffness and damage. Patients with KOA have larger variations in muscle strength and are unable to maintain a target force combined with impaired ability to perceive joint movement and positioning suggests impaired neuromuscular control (NC) may influence KOA. NC refers to the nervous system's control over muscle activation contributing to task performance. This study aims to establish the role of loss of NC in biomechanical determinants and health outcomes of KOA.
