Interventions

  • Interventional group A — BEHAVIORAL
    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 — BEHAVIORAL
    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

Study Details

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.

Arms

  • Experimental: interventional group A
    The experimental group A 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
  • Active Comparator: interventional group B
    Experimental group B 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
