Enrollment

48 participants

Start Date

May 1, 2026

Study Type

INTERVENTIONAL

Conditions

Knee Osteoarthritis (Knee OA)Knee Arthritis, Osteoarthritis

Summary

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.

Interventions

OTHERpressure Biofeedback Training

This intervention combines a standard land-based therapeutic exercise protocol with visual feedback for targeted isometric quadriceps activation. During a 45-minute session, participants first complete warm-up and conventional strengthening exercises (e.g., straight leg raises, hip abduction, step-ups). For the specific isometric component, participants lie supine with a Pressure Biofeedback Unit (PBU) airbag placed under the popliteal fossa, inflated to a baseline of 60 mmHg. They are instructed to press the knee downward to increase the dial reading by 20-40 mmHg and hold it steady for 10 seconds. This is performed for 3 sets of 10 repetitions to counteract Arthrogenic Muscle Inhibition (AMI).

OTHERBolster Foam Roll Training

Participants will complete a 45-minute exercise session consisting of a warm-up and conventional physiotherapy exercises (straight leg raises, side-lying hip abduction, step-ups, mini-squats, and stretches). For the targeted isometric component, participants are positioned supine with a firm high-density foam bolster placed under the knee. They are instructed to "crush the foam" into the table to feel the physical resistance, holding the contraction for 10 seconds. They will complete 10 repetitions across 3 sets.
