Brief summary
The aim of this study was to compare the effect of band tissue flossing method and traditional cuff method for blood flow restriction training on pain, range of motion, muscle strength and functional status in patients with knee osteoarthritis. Symptoms of this condition limit patient's ability to perform high load strengthening. Blood flow restraining training allows strengthening with lower loads. 46 subjects will be divided in two groups, 23 subjects in each group. knee extension and knee press exercises will be performed. In group A floss band was tied on thigh and in group B pneumatic cuff was applied on thigh. 40-60 years individual with knee osteoarthritis will be included. outcome measures will be assessed at baseline, after 1st session, after 2nd week and after 4th week.
Interventions
OTHERBlood flow restriction training with Floss band
seated knee extension exercise and knee press exercises (4 sets; repetitions: 30,15,15,15) performed for four weeks with three sessions per week. Exercises performed with 20% of one repetition maximum. Floss band was tied at proximal thigh with 50% stretch in proximal to distal direction starting from above the patella and moving towards groin.
OTHERBlood flow restriction training with pneumatic cuff
seated knee extension exercises and knee press exercises (4 sets; repetitions: 30,15,15,15) performed for four weeks with three sessions per week. Exercises performed with 20% of one repetition maximum. Clinical cuff was tied at proximal thigh with 40% of limb occlusion pressure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Numeric Pain Rating Scale (NPRS) | 4th week | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Knee Flexion Range of motion | 4th week | 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 |
| Knee Extension Range of Motion | 4th week | Changes from baseline in knee extension range of motion will be assessed with goniometer. It 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 strength (dynamometer) | 4th week | 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. |
| Western Ontario and McMaster Universities (WOMAC) index | 4th week | 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. |
| 30 Second Sit to Stand Test (STS) | 4th week | 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 |
| Timed Up and Go Test (TUG) | 4th week | 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. |
