The aim of the study is to examine the effects of blood flow restriction training(BFRT) with low intensity exercises on pain, range of motion and quality of life in Knee Osteoarthritis. A randomized clinical trial will be conducted at Lahore general hospital. Non-probability convenience sampling will be used, and 36 subjects, age 40-65 years will be randomly allocated into two groups by lottery method after meeting the inclusion criteria.

A randomized clinical trial will be conducted at Lahore general hospital. Non-probability convenience sampling will be used, and 36 subjects, age 40-65 years will be randomly allocated into two groups by lottery method after meeting the inclusion criteria. Both groups will receive Ultrasound therapy for 7 minutes, as common treatment. Group A will be treated with Blood flow restriction training with low intensity exercises and Group B will be treated with baseline treatment only. 3 sessions per week and total 12 sessions for 4 weeks. The outcome measures will be conducted through NPRS, Womac index for osteoarthritis,kellgren and lawrence scale and goniometry before and after 4 weeks. Data will be analyzed using SPSS software version 26.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| blood flow restriction training | Experimental | we will apply blood flow restriction training with low intensity exercises on patients with knee osteoarthritis to check pain,quality of life and range of motion. |
|
| ultrasound application only | Active Comparator | in this group we will apply ultrasound therapy on knee joint for 7 minutes. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| blood flow restriction training | Other | we will apply blood flow restriction training with low intensity exercises like knee flexion ,knee extension and straight leg raise 10 repetitions 2 sets a day and 3 times/week a rest interval of 2 minutes between exercises, for 30 minutes of this whole procedure. total 12 sessions given in 4 weeks each session of maximum 30 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| NPRS Numeric pain rating scale | The NPRS is a self-reported, or clinician administered, measurement tool consisting of a numerical point scale with extreme anchors of 'no pain' to 'extreme pain'. The scale is typically set up on a horizontal or vertical line, ranges most commonly from 0-10 or 0-100, and can be administered in written or verbal form. The patient is asked to rate his/her pain intensity and a particular time frame or descriptor is established (e.g. within the last 24 h, today, worst pain, average pain, or least pain) | 4th week |
| Measure | Description | Time Frame |
|---|---|---|
| Womac index for knee osteoarthritis | WOMAC measures three separate dimensions: Pain (5 questions), Stiffness (2 questions), and Pain, stiffness, and physical function were measured by WOMAC. This instrument is validated and recommended by the Osteoarthritis Research Society as the measure of choice when assessing health status in older adults with knee OA. Rating scale ranges from 0 (none) to 4 (extreme), with higher total scores indicating greater dysfunction.The WOMAC addresses symptoms and functional disability in separate scales . Also, the WOMAC is a patient questionnaire. |

| ultrasound therapy | Other | All subjects will be given Ultrasound therapy as per patient requirement with 1.5 Watts/cm^2 in continuous mode around knee joint. Conservative exercises(quads isometric exercise, pillow squeeze, heel raise, straight leg raise and side leg raise) will be applied for 3 times per week (daily one set of 10 repetitions) They will be given this treatment for 3 times per week |

| Knee Related QOL (QUALITY OF LIFE) Subscale From KOOS | The Knee injury and Osteoarthritis Outcome Score (KOOS) was developed as an extension of the WOMAC Osteoarthritis Index with the purpose of evaluating short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL). The effect size is generally largest for the subscale QOL followed by the subscale Pain. The KOOS is a valid, reliable and responsive self-administered instrument that can be used for short-term and long-term follow-up of several types of knee injury including osteoarthritis | 4th week |
| Universal goniometer | The most common tool for measuring ROM has been the universal goniometer (UG; full-circle manual goniometer. The advantage with the UG is its low cost, but both hands are needed to perform the measurements | 4th week |
