Comparative Effects of Clamshells and Frog Pump Exercises

Study Overview
=================
Brief Summary
-----------------
Iliotibial band syndrome is where a tendon called iliotibial band gets irritated or swollen from rubbing against hip or knee when it gets too tensed. Iliotibial band (ITB) syndrome (ITBS) is the most common cause of lateral knee pain among athletes who are involved in sports that require continuous running or repetitive knee flexion and extension. The incidence ranges from 1.6% to 12% in runners. The aim of the study is to compare the effects of clamshells and frog pump exercises on gluteus medius strengthening and lower extremity function in runners with iliotibial band syndrome.

Detailed Description
-----------------
This study will be a randomized clinical trial and will be conducted in Pakistan Sports Board Lahore. Non-probability convenient sampling will be used to collect the data. Sample size of 32 subjects with age group between 18-30 years (males) will be taken. Data will be collected from the runners with tight ITB, by using tools LEFS, HOS-SS, and Hand held dynamometer. An informed consent will be taken. A total of 26 subjects will be selected by following inclusion and exclusion criteria and will equally divided in to two groups by random number generator table. Both the Groups will continue the conventional training with Group A will receive clamshell Exercise, and Group B will receive frog pump exercise in their respective training programs. Outcome measures will be measured at baseline and after 2 weeks. Data analysis will be done by SPSS version 25.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Group A: Clamshell Exercise<br>Group B will be given frog pumps exercises in their regular training program. These exercises are given as: In (0-2) week ,2 sets 10 repetitions In (2-4)week, 3 sets of 10 repetitions In (4-6)week, 3 sets of 15 repetitions | Other: Clamshell Exercise<br>* Clamshell Exercise: The clamshell exercise keeps the hips moving, it strengthens both the gluteus medius AND gluteus maximus. The gluteus medius is the main abductor (movement away from the midline of the body) and external rotator of the hip.<br>|
| Active Comparator: Group B: Frog Pump Exercise<br>Group B will be given frog pumps exercises in their regular training program. These exercises are given as: In (0-2) week ,2 sets 10 repetitions In (2-4)week, 3 sets of 10 repetitions In (4-6)week, 3 sets of 15 repetitions | Other: Frog pump exercise<br>* Frog pump exercise: The frog hip thrust mainly targets the gluteal muscles responsible for thigh extension and abduction. The exercise also works the hamstrings on the back of the thighs which helps in hip extension.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Manual Muscle Testing (MMT) | For measuring the strength of Hip muscles, Manual Muscle Testing (MMT) is used. Manual Muscle Testing (MMT) is a standardised set of assessments that measure muscle strength and function against specific criteria and is commonly used in clinical practice by physiotherapists. Grading Scale Range: 0 to 5 0 None No visible or palpable contraction Trace Visible or palpable contraction with no motion Poor Full ROM gravity eliminated Fair Full ROM against gravity Good Full ROM against gravity, moderate resistance Normal Full ROM against gravity, maximum resistance | upto 6th weeks | 
| Hip Outcome Score (HOS) | The hip outcome score (HOS) is a questionnaire used to measure the function of the Hip. The HOS is a patient-completed measure that consists of an Activities of Daily Living subscale (17 scored items) and a Sports subscale (9 scored items) in which the response options are presented as 5-point Likert scales (Scores 0-4). | upto 6th weeks | 
| Lower Extremity Functional Scale (LEFS) | The lower extremity functional scale (LEFS) measures the function and disability of the lower extremity. LEFS is a well-known and validated instrument for the measurement of lower extremity function. The LEFS was developed in a group of patients with various musculoskeletal disorders. The LEFS rating scale categories are: (1) extreme difficulty or unable to perform, (2) quite a bit of difficulty, (3) moderate difficulty, (4) a little bit of difficulty, and (5) no difficulty. LEFS score = SUM (points for all 20 activities) Interpretation: Minimum score: 0 Maximum score: 80 The lower the score the greater the disability. | upto 6th weeks |
