Efficacy of Low Blood Flow Restricted Exercise on Increasing Muscle Strength in Patients with Knee Osteoarthritis Comparing with Conventional Strength Training

Abstract

Background: The prevalence of OA knee is diagnosed with radiographic features 15% of patients were symptomatic
in one study. OA affects nearly 6% of adults. Female sex is more common. 13% of females and 10% of male in 60
years are affected with OA and in 70 years of population rises to 40%.
Purpose: To find the efficacy of low blood flow restricted resistance exercise on increasing muscle strength in
patients with knee OA compared with conventional strength training using NPRS for pain and knee ROM.
Materials and Methods: A total of 60 subjects were assigned in this study. The NPRS and knee ROM were used
to calculate pre-and post-test results. Each session included three sets of five repetitions with a ten-second hold in
between. The tables were tabulated and statistically evaluated.The entire process was conducted from November
2022 to April 2023.
Result: According to the statistical analysis, both groups had a statistically significant improvement between their
pre and post-exercise values (p<0.0001). There is also a significant variation in post-exercise results between the
two groups (p<0.0001), indicating that blood flow restriction with exercises is more effective than conventional
strength training with exercises.
Conclusion: Blood flow restriction has been shown to be more effective than conventional strength training at
relieving pain and increasing knee ROM.
