Summary

Objective is to compare the effects of routine physical therapy with and without low intensity blood flow restriction on pain and quadriceps muscle strength in women with knee osteoarthritis.

A single blinded randomized controlled trial conducted at Department of Physiotherapy, University of Lahore Teaching Hospital, Defense Road, Lahore.

Total 60 participants were randomly assigned in to two groups, with 30 in each group The intervention group received routine physiotherapy program combined with Low Intensity Blood Flow Restriction Technique (LI-BFR. While control group were treated with only routine physiotherapy.

Dynamometer was used to assess the knee extensor strength while Knee injury and osteoarthritis outcome score was used to record any exacerbation in pain and effects of BFR on activities of daily living. Training load determined 20% of 1RM. Data analysis had done on SPSS version 23.

Conditions

  • Osteoarthritis, Knee

Interventions

OTHER

BFRT

Patients of Interventional group were treated with routine physiotherapy program combined with LI-BFR consist of 10 minutes' session 3 per week for 12 weeks. In order to determine the training load 20% of 1RM, participants had performed knee extension in full range with a challenging weight. After each test, participants rated their perceived exertion level on (RPE) scale to determine the difficulty of the resistance. The derived 1RM was used to determine the 20% 1RM load used for low-load training. Blood flow restriction proximal to the working muscles achieved through using pressure cuffs. The cuff was applied to the proximal thigh. During week 1 the inflation pressure was 100mmHg. Final exercise pressure based the week of the training. Quadriceps size was measured by tape measures thigh
