Blood Flow Restriction Training in Knee Osteoarthritic Patients

Changes from baseline will be assessed using NPRS scale. It is a one-dimensional measure of pain severity in adults including those suffering from chronic pain. Scale has ratings of 0 to 10, with higher points indicating higher levels of pain severity. it is a valid tool for assessing pain in knee OA patients.

Changes in knee flexion range of motion from baseline will be assessed using universal goniometer. Goniometer is the most common instrument utilized for measuring available range of motion. Universal Goniometer Comes in two variations one is short arm whereas one is long arm. The one with short arm is used for smaller joints like the wrist, elbow, or ankle. On the other hand, long arm goniometers provide greater accuracy for knee and hip joints which have long bones acting as levers

Quadriceps muscle strength changes from baseline will be assessed using crane scale dynamometer. Participant sits in chair with hips and knees flexed to 90 degrees. The hook of dynamometer is secured to the ankle with a strap, while from behind the dynamometer is fixed to leg of chair to provide a stable anchor. As the participant performs knee extension the force generated is recorded in newtons or kilograms. It is a valid and reliable tool for assessing strength of knee extensors.

WOMAC index was developed in order to fill the need for an outcome instrument that could be responsive to change in OA-related symptoms following a clinical trial. It includes five questions about pain, two about stiffness, and seventeen on degree of disability of activities of daily living. total score is converted to percentage. higher scores mean severe symptoms.

The 30 Second Sit to Stand Test (STS) is also known as 30 Second Chair Stand Test (30CST), was initially designed for testing leg strength and endurance in older adults. It is used for adults of 18-64 years, older adults (65 years and above), and people with osteoarthritis. A person stands up and sits down five times as quickly and safely as possible, with their arms folded across their chest, A longer time indicates weaker leg strength and a greater risk of falls. It records the number of times a person can sit and stand within 30 seconds

This test is for assessing ambulatory transition in knee OA patients. For this test participant stands from armed chair, walks with comfortable pace to a line 3 m away, at end point turns, and returns to sitting position in chair. Participant can't use walking aid during task. Time is recorded in which task is done.
