Efficacy of Progressive Resistance Training Protocol in Avascular Necrosis Patient: A Case Study

The purpose of this case study was to investigate the effect of progressive resistance training protocol on pain, restricted movement, strength, and functional ability of patient with avascular necrosis (AVN). A single case study was done on patient with AVN, baseline data was collected pre and post the treatment and outcome measures pain, range of motion (ROM) of hip and muscle strength were assessed using the Numerical Pain Rating Scale (NPRS), Goniometer and Manual Muscle Testing (MMT) respectively. The treatment program was a total of 4 weeks with 3 sessions per week. Results showed a significant decrease in pain intensity and an increase in range of motion and strength. This study concluded that a progressive resistance exercise training program showed substantial improvement in hip musculature strength and helped in regaining pain-free range of motion in a patient with AVN.
