Effect of Perturbation Training and Dynamic Resistance Exercises in Patients with Grade II Knee Osteoarthritis: Case Report

Osteo Arthritis of the knee manifests as stiffness, mobility restriction, and difficulty with daily activities. Perturbation training, a method for fostering the growth of motor abilities, whereas resistance training improves physical function, reduces OA pain, and lowers self-reported disability.  This study is to analyze and understand the effect of perturbation training and dynamic resistance exercise training on muscle strength and knee extension range of motion in grade II knee osteoarthritis. Grade II Osteoarthritis knee patient was recruited for this study. 20 sessions of perturbation training with dynamic resistance exercises for the affected knee joint for 30 minutes, session with 5 sessions per week were given. Pre and Post Intervention values of muscle strength of 1 Repetition Maximum for knee extensor and knee extension range of motion was taken and analyzed. This case study results had shown significant improvement in the outcome of muscle strength in 10 RM and knee extension ROM after the combined intervention of perturbation training and resistance exercise for Grade II OA Knee Patients. Thus this study may be concluded that there was a significant improvement in knee extensor muscle strength (1 RM) in the affected knee joint in a patient with grade II knee osteoarthritis after combined intervention perturbation training and dynamic resistance exercises.
