The most important aspect of physical fitness is flexibility, which can be greatly impacted by bad posture. Long periods of sitting in school going children can cause the hamstring muscles to shorten because they bend the knee. There are numerous methods for improving hamstring flexibility, but very few of them produce immediate results. The purpose of this study will be to compare between the immediate effects of hold-relax proprioceptive neuromuscular facilitation and muscle energy technique (MET) for hamstring flexibility in school going children. This will be the randomized clinical trial in which total time of six month will be utilized after the approval from BASR. Data will be collected from Unique Science School Al-Rehman Campus, Lahore. 106 participants will be taken with 05-12 years of age through purposive sampling technique. Participants will be divided into two equal groups. Participants in group A will be given hold-relax PNF and the group B will underwent METs (reciprocal inhibition). Hamstring ROM will be assessed through AKET. Measurements will be taken by goniometer. Wong-Baker faces pain scale (WBFPS) and Timed 'Up and Go' (TUG) test will be used to evaluate pain and functional mobility respectively. Data will be analyzed on SPSS version 25. Results after statistical analysis will show which technique is more effective and will have best outcomes.
The most important aspect of physical fitness is flexibility, which can be greatly impacted by bad posture that might occur from a sedentary lifestyle of a person and a reduction in the soft tissues' flexibility cause serious musculoskeletal injuries. Long periods of sitting in school going children can cause the hamstring muscles to shorten because they bend the knee. There are numerous methods for improving hamstring flexibility, but very few of them produce immediate results. The literature demonstrated that the two most successful stretching methods to compare were hold-relax and MET but there is paucity to determine their immediate effectiveness.
The purpose of this study will be to compare between the immediate effects of hold-relax proprioceptive neuromuscular facilitation and muscle energy technique (MET) for hamstring flexibility in school going children and to determine which strategy improves hamstring flexibility in school-aged children the fastest and with the best results. This will be the randomized clinical trial in which total time of six month will be utilized after the approval from BASR. Data will be collected from Unique Science School Al-Rehman Campus, Lahore. 106 participants will be taken with 05-12 years of age through purposive sampling technique. Participants will be divided into two equal groups. Participants in group A will be given hold-relax PNF and the group B will underwent METs (reciprocal inhibition).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group A: Application of Hold-Relax PNF Technique | Active Comparator | A hold-relax technique that entails stretching the muscle to its maximum length. Participant will be in supine position. The hamstring muscle will be stretched for 7 to 10 seconds while the individual reported only a slight stretch in the muscle. The participant then attempts to lower his leg towards the table while being resisted by the researcher, isometrically contracting his hamstring muscle for 3 seconds. The patient then instructed to relax for five seconds. The researcher then passively stretched the muscle until a slight sensation of stretch was experienced. The stretch will maintain for seven seconds. There were five repetitions of this sequence, each one 20 seconds apart from the previous one |
|
| Group B: Application of Muscle Energy Technique | Active Comparator | Group B will receive a Muscle Energy Technique (MET) applying the reciprocal inhibition principle. Participant will be in supine lying and the affected muscle held in a mid-range position. The Reciprocal Inhibition-MET group stretched for 10 to 60 seconds after performing an isometric contraction of the muscle opposite the one that needed to be stretched for 7 to 10 seconds (30%-50% of the time) followed by 5 second rest interval. With a pause of 20 seconds in between each repetition, this sequence was performed five times(52). The readings for Active knee Extension (AKE), TUG test and WBFPS before and after treatment session determined the improvement regarding the treatment outcomes. |

| Goniometer | The universal full circle goniometer is arguably the preferred instrument for measuring ROM for the majority of applications to the extremities. This version, which has a body, moving arm, and stationary arm, is the most prevalent. When comparing radiographic measurements with goniometric measurements in sedated and unsedated cats, joint measurements did not change significantly by measurement type. Cronbach alpha values for goniometric joint measurements were more than 0.99. | eight weeks |
| Active Knee Extension Test (AKET) | The Active Knee Extension Test measures the range of active knee extension when the hip is flexed as well as the length of the hamstring muscles. If the body positions are sufficiently stable, this test has a high degree of reliability. This test, a self-monitored variation of the active knee extension test, has also proven to be successful when performed by the person being tested. Among healthy individuals, the inter-rater and intra rater dependability has been proven. | eight weeks |

| Wong Baker Faces Pain Scale (WBFPS) | The Wong Baker Faces Pain Scale is a self-report tool designed to determine how much pain children are experiencing. Using scales of various facial expressions and matching a child's pain level to a similar face is one method of measuring pain in children. The Faces scale is an ordinal outcome measure that contains a minimal and predetermined number of categorical responses that are presented in a predetermined pattern. It is used to measure the rating of pain. |

| Timed 'Up and Go' Test (TUG) | The Timed Up and Go test (TUG test), also used to measure functional mobility in children, is a useful tool. The TUG test calculates how long it takes to stand up, go forward 10 feet, turn around, move backward, and then sit down. The TUG test shows strong consistency and correlation with other evaluation instruments. | Eight Weeks |
