Weighted Dangling Exercises vs Vastus Medialis Oblique Muscle Neuromuscular Stimulation for Knee Osteoarthritis
Sponsor: University of Lahore
Summary
This randomized controlled trial aims to compare the effectiveness Weighted dangling exercises versus vastus medialis oblique muscle neuromuscular electrical stimulation(VMO+NMES) in patients with knee osteoarthritis. The study will recruit 48 participants (accounting for 10% attrition), aged 40-60 years, from University of Lahore Teaching Hospital using convenience sampling. Participants will be randomly allocated into two groups: an interventional group receiving WDE and other interventional group undergoing VMO strength training with NMES. Both interventions will be administered three times per week for 8 weeks under professional supervision. Outcome measures including pain intensity (NPRS), Functional Disability (Western Ontario and McMaster Universities Osteoarthritis Index),Muscle Strength (MMT) will be assessed at baseline, 4 weeks, and 8 weeks. Data will be analyzed using SPSS, with appropriate parametric or non-parametric tests applied after checking data normality. Ethical approval will be obtained, informed consent will be secured, and participant confidentiality will be strictly maintained.

Conditions
Interventions
Interventional group A
The one group will receive weighted dangling exercise. A gravity-assisted flexion-extension movements of the lower legs Ankle cuffs weight worn during the exercise while seated on a high couch with their legs hanging down
interventional group B
This group receive neuromuscular electrical stimulation (NMES) specifically targeting the vastus medialis oblique (VMO). The NMES parameters are as follows: electrodes were placed above the superomedial border of the patella, oriented at a 55° angle to the vertical. The stimulation frequency set at 50 Hz, with a pulse duration of 250 µs and a duty cycle of 10 seconds ON and 30 seconds OFF
