This comparative experimental study aims to evaluate the effectiveness of Sensory-Modulated Graded Weight-Bearing Physiotherapy (SMGWBP) in patients with knee osteoarthritis and compare treatment outcomes between male and female participants. Participants will receive a 6-week physiotherapy program with assessments conducted at baseline (pre-intervention), mid-intervention (3 weeks), and post-intervention (6 weeks) using validated outcome measures.
Knee osteoarthritis (KOA) is a common degenerative joint disorder associated with pain, impaired physical function, reduced proprioception, decreased mobility, and poor quality of life. Physiotherapy plays a central role in the conservative management of KOA by reducing pain and improving functional performance. Sensory-Modulated Graded Weight-Bearing Physiotherapy (SMGWBP) integrates sensory stimulation with progressive weight-bearing exercises to enhance neuromuscular control, balance, proprioception, and functional recovery. This comparative experimental study aims to evaluate the effectiveness of SMGWBP in individuals with Kellgren-Lawrence grade II or III knee osteoarthritis and to compare treatment outcomes between male and female participants. A total of 52 participants will be recruited through purposive sampling. All participants will receive a standardized 6-week physiotherapy program consisting of three supervised sessions per week. Outcome assessments will be performed at three time points: baseline (pre-intervention), mid-intervention (3 weeks), and post-intervention (6 weeks). The primary and secondary outcome measures include pain intensity measured using the Visual Analog Scale (VAS), physical function using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), proprioception using the Joint Position Sense (JPS) test, gait performance using the Six-Minute Walk Test (6MWT), health-related quality of life using the Short Form-36 (SF-36), and treatment compliance. The study will examine changes in these outcomes over time and compare the effectiveness of the intervention between male and female participants.

A structured six-week Sensory-Modulated Graded Weight-Bearing Physiotherapy Programme consisting of three supervised sessions per week (18 sessions total). Each session includes warm-up, sensory modulation, proprioceptive training, graded weight-bearing strengthening, functional mobility exercises, and cool-down activities. The programme progresses through three phases: Weeks 1-2 focus on sensory activation and proprioceptive training; Weeks 3-4 on graded weight-bearing strengthening; and Weeks 5-6 on functional weight-bearing integration. Exercises are progressed according to participant tolerance, pain severity, and functional performance. Both male and female groups receive the same intervention.
