About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 40-60 years

Pain more than or equal to 3 on NPRS

Range of motion ≤ 100-degree flexion and ≤ 0-degree extension

Those who have knee osteoarthritis, according to KL (Grade 1 and 2)

Disqualifiers

Cardiovascular condition e.g., hypertension, thromboembolism, lymphatic diseases etc.

Muscle/tendon/ ligament injuries

Any surgery, skin infection, trauma, pregnancy, fracture and fall

Trial design

Design model

Parallel

Treatments tested in this trial

  • Blood flow restriction training with Floss band

    Other intervention

    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.

  • Blood flow restriction training with pneumatic cuff

    Other intervention

    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.

Treatment groups

46 Participants
are divided into 2 treatment groups
Group A: Blood flow restriction with Floss band (group A)Experimental treatment 1 intervention
Group B: Blood flow restriction with pneumatic cuff (group B)Experimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Numeric Pain Rating Scale (NPRS)

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.

Time frame
4th week

Secondary outcomes

1

Knee Flexion Range of motion

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

2

Knee Extension Range of Motion

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

Time frame
4th week
3

Quadriceps strength (dynamometer)

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.

Time frame
4th week
4

Western Ontario and McMaster Universities (WOMAC) index

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.

Time frame
4th week
