About this study
Official title: Effects of Clamshell and Frog Pump Exercises on Pain, Range of Motion, and Functional Disability in Long-standing Sales Workers With Iliotibial Band Syndrome
The study will be randomized clinical trial. This study will be conducted at the University of Lahore Teaching Hospital, Lahore, Pakistan. A sample size of 92 will be randomly allocated into two experimental groups, (46 participants in each group), by the lottery method. All the screened and willing participants were randomly allocated into two groups (Group A: Experimental group / Clamshell exercise + Conservative management, Group B: Comparative Group / Frog pump exercises + Conservative management) by lottery method. The participants randomly allocated to Group A will receive conservative treatment along with clamshell exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes. The clamshell starts with lying on the side, with legs stacked and knees bent at a 45-degree angle. Group B will receive conservative treatment along with Frog pump exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes. The Frog pump exercise will start with lying on your back, arms by sides, palms facing down. Data will be assessed by the assessor at baseline, and at the end of the 12th week.

Screening: All the participants will be assessed for the eligibility criteria. Patients fulfilling the eligibility criteria will be asked to sign the consent forms before entering them into the study.
Randomization and Allocation: All the screened and willing participants will be randomly allocated into two groups (Group A: Experimental group / Clamshell exercise + Conservative management, Group B: Comparative Group / Frog pump exercises + Conservative management) by lottery method.
Blinding: This study will be a single-blinded study in which the assessor will be blinded.
Intervention Group A: Experimental Group (Clamshell exercise + Conservative management) The participants randomly allocated to Group A will receive conservative treatment along with clamshell exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes. The clamshell starts with lying on the side, with legs stacked and knees bent at a 45-degree angle. Rest the head on the lower arm and use the top arm to steady the frame. Hipbones are stacked on top of one another, as there is a tendency for the top hip to rock backward. Engage the abdominals by pulling your belly button in, as this will help to stabilize the spine and pelvis. Keeping the feet touching, raise the upper knee as high as they can without shifting the hips or pelvis. They don't move their lower leg off the floor. Pause, and then return the upper leg to the starting position on the ground. 20 reps will be done on each side. Each exercise will be performed in 3 sets of 10 repetitions with 1 minute of rest after every exercise set. The whole treatment session will start with 15 min warm-up and end with 5 min cool-down, delivered 3 times a week for 12 weeks yielding a total of 36 sessions within 3 months and the duration of each session will be of 35-45 minutes in Group A.
Group B: Comparative Group (Frog pump exercises + Conservative management) 19 Group B will receive conservative treatment along with Frog pump exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes. The Frog pump exercise will start with lying on your back, arms by sides, palms facing down. Alternatively, make fists with your hands, rest the elbows on the floor, and lift the fists so that your forearms are perpendicular to the floor. Then bend the knees and press the soles of the feet together so that the legs create a "frog legs" or "butterfly" shape. Pressing the outer edges of the feet against the floor, engage the core, and use the glutes to lift the hips. Make sure the shoulders and upper back remain anchored to the floor. Pause, then slowly lower the hips to the floor. . 20 reps will be done on each side. Each exercise will be performed in 3 sets of 10 repetitions with 1 minute of rest after every exercise set. The whole treatment session will start with 15 min warm-up and end with 5 min cool-down, delivered 3 times a week for 12 weeks yielding a total of 36 sessions within 3 months and the duration of each session will be of 35-45 minutes in Group B.
Outcome Variables:

What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Pain Rating Scale)
Numeric rating scales consist of a series of numbers rating pain intensity, typically from 0 to 10 or 0 to 100, with 0 being "no pain" and 10 or 100 "the worst pain imaginable."
Measured: 12 weeks
Goniometry)
A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position.
Measured: 12 weeks
Lower Extremity Functional Scale (LEFS)
The Lower Extremity Functional Scale (LEFS) is a questionnaire containing 20 questions about a person's ability to perform everyday tasks. The LEFS can be used by clinicians as a measure of patients' initial function, ongoing progress and outcome, as well as to set functional goals.
Measured: 12 weeks

The participants randomly allocated to Group A will receive conservative treatment along with clamshell exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes. The clamshell starts with lying on the side, with legs stacked and knees bent at a 45-degree angle. Group B will receive conservative treatment along with Frog pump exercise. The treatment will start with routine physiotherapy comprised of TENS (setting was in a conventional mode, with a frequency of 80 Hz and a pulse duration of 50-100 μs. The intensity of TENS current was set to produce a strong tingling sensation, but without pain.) A hot pack will be used for 10 minutes and stretching exercises for the whole body as a warm-up, before starting the main treatment regime for 15 minutes.
