About the trial
What the trial wants to find out
The current study will be a single-blinded, two-arm parallel group randomized clinical trial involving 48 participants. The trial will compare Pressure Biofeedback training with Bolster Foam Roll training. Interventions will be delivered three times per week for eight weeks. The primary outcomes will include pain intensity, functional status, and muscle activation. Assessments will be conducted at baseline (week 0), mid-intervention (week 4), post-intervention (week 8), and follow-up (week 12). The study will be conducted at the outpatient departments of Sir Ganga Ram Hospital (SGRH) and Mayo Hospital Lahore. The hypothesis is that there is a difference between Pressure Biofeedback Training and Bolster Foam Feedback Training regarding pain reduction, muscle activation, and patient-reported quality of life compared to Bolster Foam rolling training among knee osteoarthritis patients.
The 2 groups in the trial
- Pressure Biofeedback TrainingTreatment being tested
Participants will receive 45-minute sessions including warm-up and conventional physiotherapy. For targeted isometric training, participants lie supine with a Pressure Biofeedback Unit airbag under the popliteal fossa inflated to 60 mmHg. They press the knee downward to move the dial up 20-40 mmHg, holding for 10 seconds across 3 sets of 10 repetitions
- Bolster Foam Feedback TrainingExisting treatment, for comparison
Participants will receive the same 45-minute sessions with warm-up and conventional physiotherapy. For targeted isometric training, participants lie supine with a firm high-density foam bolster under the knee. They are instructed to "crush the foam" into the table to feel the resistance, holding for 10 seconds across 3 sets of 10 repetitions
Treatment: Bolster Foam Roll Training
