US Clinical Trial NCT03980964

Prospective Evaluation of Neuromuscular Electrical Stimulation (NMES) for Reducing Pain and Improving Functional Outcomes in Knee Osteoarthritis (OA) Patients  Jun 7, 2019

The study will be conducted at Lenox Hill Hospital, Northwell Health, located in New York, New York, and involve a total of 120 patients. All study patients will be evenly divided into two groups: (a) conductive garment and mobile app with NMES therapy; (b) conductive garment and mobile app without NMES therapy (sham).

Eligible patients will be evaluated according to the time and events schedule. Clinical outcomes will be assessed from 1 to 10 days before day of intervention and followed up after intervention over a 24 weeks ± 1 week study period.

These two groups will be analyzed using several outcome measures including validated patient-reported outcome measures including Visual Analogue Scale (VAS) pain level, the Knee Injury and Osteoarthritis Outcome Score (KOOS) JR., KOOS ADL, and WOMAC survey. Functional measures include isometric quadriceps strength, Time Up and Go (TUG), 6 minute walk test, repeated chair rise test, stair climb test, and number of steps recorded by an Apple Watch Series 3 or a Samsung watch. Reduction of use of anti-inflammatory medications (NSAIDS) and narcotics, use of ambulation assist devices, plan for TKA procedure survey, device compliance use, and patient satisfaction survey will be tracked The primary endpoint for the study is Visual Analogue Scale (VAS) pain The proprietary app for this product will be used to track device usage (intensity, duration of session, frequency of use), VAS, WOMAC, and KOOS JR.
