Study Overview
=================
Brief Summary
-----------------
The study will be randomized controlled trial. This study will be conducted in University of Lahore Teaching Hospital, Lahore, Pakistan. A sample size of 84 will be randomly allocated into two experimental groups, (42 participants in each group), by computer generated random number list. The participants,randomly allocated to the experimental group A, will receive high intensity resisted exercises ,in addition with routine physical therapy as TENS (transcutaneous electrical nerve stimulator), Hot pack, Deep friction massage Each session will be of 35-45 minutes with 5 minutes warm up, 35 minutes for training session and lastly 5 minutes for cool down • Participants in experimental group B, will receive Low intensity resisted exercises in addition with routine physical therapy

Detailed Description
-----------------
Recruitment: Participants will be recruited and referred by orthopedic doctor, University of Lahore Teaching Hospital to Physical Therapy Department. The study will be randomized controlled trial. This study will be conducted in University of Lahore Teaching Hospital, Lahore, Pakistan. A sample size of 84 will be randomly allocated into two experimental groups, (42 participants in each group), by computer generated random number list. The participants,randomly allocated to the experimental group A, will receive high intensity resisted exercises ,in addition with routine physical therapy as TENS, Hot pack, Deep friction massage Participants in experimental group B, Low intensity resisted exercises in addition with routine physical therapy Both experimental groups will receive sixteen treatment sessions and those will be given over a period of eight weeks (2 sessions per week, each session of 35-45 minutes with 5 minutes warm up and lastly 5 minutes for cool down in both groups. Outcome measure will be taken by assessor at baseline, and at the end of 8th week (at the end of last treatment session) through Numeric pain rating scale and KOOS Randomization and Allocation: Afterwards, participants confirming the eligibility criteria will be randomly allocated, through computer generated random number list , into two experimental groups (Group A, Group B). Blindness: Study will be single, assessor blinded and an independent investigator will perform randomization and will inform the patients and therapist about the allocation. Intervention: Leg presses, knee extension, hip adduction and hip abduction exercises will be performed by patients. There will be a warm up sets for 1 repetition maximum with 2 min gap between both sets (leg press + knee extension exercises) (hip abduction and hip adduction) patients will ask to perform. Duration: Sixteen treatment sessions will be given over a period of eight weeks (2 sessions per week, each session of 35-45 minutes). Outcome Variables and Measures Pain (Numeric pain rating scale) Functional disability (KOOS) ROM (Universal Goniometer) Outcome measures will be taken at baseline and at the end of last treatment session i.e. 8th week. Collected data will be than analyzed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: High intensity<br>Intervention: Leg presses, knee extension, hip adduction and hip abduction exercises will be performed by patients. There will be a warm up sets for 1 repetition maximum with 2 min gap between both sets (leg press + knee extension exercises) (hip abduction and hip adduction) patients will ask to perform.Routine physical therapy including TENS, Hot pack and Deep friction massage along with high intensity exercises will also be delivered along with Muscle Energy Technique. Experimental:High intensity will be treated with high intensity exercises in such a way that 1st and 2nd week; resistance training will be of 50% 1RM with 4 sets of 10 repetitions. 3rd and 4th week: resistance training will be of 70% 1RM with 4 sets of 10 repetitions. 5th and 6th week: the training will be of 80% 1RM with 4 sets of 10 repetitions Last 4 sessions will be: 7th and 8th week: resistance training will be of 80% 1RM with 5 sets of 10 repetitions. | Other: HIGH INTENSITY PROGRESSIVE RESISTED EXERCISE<br>* Intervention:Leg presses, knee extension, hip adduction and hip abduction exercises will be performed by patients. There will be a warm up sets for 1 repetition maximum with 2 min gap between both sets (leg press + knee extension exercises) (hip abduction and hip adduction) patients will ask to perform. Both groups will receive routine physical therapy (Tens, Hot pack, Deep friction massage) in addition with experimental interventions<br>|
| Experimental: Low intensity<br>Intervention: Leg presses, knee extension, hip adduction and hip abduction exercises will be performed by patients. There will be a warm up sets for 1 repetition maximum with 2 min gap between both sets (leg press + knee extension exercises) (hip abduction and hip adduction) patients will ask to perform.Routine physical therapy including TENS, Hot pack and Deep friction massage along with Low intensity exercises will also be delivered along with Muscle Energy Technique. Experimental:Low intensity Group B will be treated with low intensity exercise in such a way that, 1st and 2nd week; Resistance training will be of 20% 1RM with 4 sets of 15 reps 3rd and 4th week Resistance training will be of 30% 1RM with 4 sets of 15 reps 5th and 6th week: the training will be of 40% 1RM with 4 sets of 15 reps Last session will be: 7th and 8th week; Training of 40% 1RM with 5 sets of 15 reps | Other: LOW INTENSITY PROGRESSIVE RESISTED EXERCISE<br>* Intervention:Leg presses, knee extension, hip adduction and hip abduction exercises will be performed by patients. There will be a warm up sets for 1 repetition maximum with 2 min gap between both sets (leg press + knee extension exercises) (hip abduction and hip adduction) patients will ask to perform.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Numeric Pain Rating Scale (NPRS) | The NPRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain | 8 weeks | 
| Knee injury and Osteoarthritis Outcome Score (KOOS) | The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a knee-specific instrument, developed to assess the patients' opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 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) | 8 weeks | 
| Range of motion | Range of motion is the extent of movement of a joint, measured in degrees of a circle. Universal goniometer (UG) will be used to evaluate range of motion (ROM) | 8 weeks |
