Clinical Trial Summary

the study aims to assess the efficacy of two interventions, namely the muscle energy technique and the hamstring Nordic lower exercise, in addressing hamstring tightness among young athletes in Pakistan.

Description:

Title: The Effectiveness of Muscle Energy Technique and Hamstring Nordic Lower Exercise in Managing Hamstring Tightness Among Young Athletes of Pakistan Objective: The primary objective of this study is to investigate the effectiveness of two interventions, the muscle energy technique and the hamstring Nordic lower exercise, in managing hamstring tightness among young athletes from Pakistan. Background: Hamstring tightness is a prevalent issue among athletes, which can lead to reduced flexibility, increased risk of injury, and impaired athletic performance. The muscle energy technique is a manual therapy approach that involves active muscle contractions and stretches to improve muscle flexibility and restore normal range of motion. Conversely, the hamstring Nordic lower exercise is a specific eccentric strengthening exercise that targets the hamstring muscles and aims to improve their lengthening capacity. Study Design: A randomized controlled trial will be conducted to evaluate the efficacy of the two interventions. Young athletes from Pakistan with hamstring tightness will be recruited as participants. They will be randomly assigned to one of two intervention groups: the muscle energy technique group or the hamstring Nordic lower exercise group. The interventions will be administered by trained healthcare professionals under supervision, following a specific duration and frequency. Outcome Measures: The primary outcome measure of interest in this study is the change in hamstring tightness. The measurement tools used to assess this outcome will be reliable and validated. Baseline assessments will be conducted before the intervention period, and post-intervention assessments will take place immediately after the intervention period. Secondary outcome measures may include improvements in hamstring flexibility, functional performance, and self-reported symptoms related to hamstring tightness. These secondary measures will provide a comprehensive evaluation of the effectiveness of each intervention. Data Analysis: Data will be analyzed using appropriate statistical methods. The outcomes between the two intervention groups will be compared to determine the relative effectiveness of the muscle energy technique and the hamstring Nordic lower exercise in managing hamstring tightness. Implications: The findings of this research will offer valuable insights into the most suitable intervention for managing hamstring tightness among young athletes in Pakistan. This information can contribute to the development of targeted rehabilitation protocols and injury prevention strategies in this specific population. Furthermore, the results may also have broader implications for similar populations of athletes globally who face similar issues with hamstring tightness. Conclusion: By evaluating the effectiveness of the muscle energy technique and the hamstring Nordic lower exercise, this study aims to contribute to the advancement of evidence-based interventions for managing hamstring tightness. The results will be disseminated through scientific publications and presented at relevant conferences to ensure that the knowledge reaches the appropriate healthcare professionals, coaches, and athletes.

Intervention

Other:
• post facilitation stretch
PFS Post-Facilitation Stretch Participants in this arm received the intervention of post-facilitation stretch technique. Post-facilitation stretch involves the application of manual stretching techniques to the targeted muscles after a facilitation phase, which aims to enhance muscle extensibility. The participants underwent a standardized post-facilitation stretch protocol focusing on the hamstring muscles.
• post isometric relaxation
Participants in this arm of the study received the intervention of post-isometric relaxation technique. Post-isometric relaxation involves the application of isometric contraction followed by a relaxation phase to promote muscle lengthening and improve flexibility. The participants underwent a standardized post-isometric relaxation protocol targeting the hamstring muscles.
• hamstring nordic lower
Participants in this arm received the intervention of hamstring Nordic lower exercise. The hamstring Nordic lower exercise is a challenging eccentric exercise that specifically targets the hamstring muscles. Participants performed the exercise under supervision and followed a standardized protocol for the number of repetitions, sets, and rest intervals.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	hamstring nordic Lower test	The hamstring Nordic lower test is a functional assessment that evaluates the eccentric strength and endurance of the hamstring muscles. During the test, the participant kneels with the ankles secured and gradually lowers their upper body towards the ground while maintaining control. The goal is to use the hamstrings to control the descent and return to the starting position. This test specifically targets the eccentric contraction of the hamstrings, which is crucial for deceleration, change of direction, and injury prevention. By assessing hamstring strength and endurance, the test can identify weaknesses or imbalances that may increase the risk of hamstring injuries.	phase 1 at baseline

Primary	YMCA sit & reach box	The YMCA sit and reach box is a commonly used tool to measure and assess hamstring and lower back flexibility. It consists of a box or platform with a measuring scale and a sliding panel. The participant sits with their legs extended, placing their feet against the box. They then reach forward with both hands, sliding the panel as far as possible along the measuring scale while keeping their knees straight. The distance reached is recorded as the measurement of flexibility. The YMCA sit and reach test provides an objective measurement of hamstring and lower back flexibility and is widely used in research, fitness testing, and clinical assessments. It is a simple and practical tool to evaluate an individual's flexibility level and monitor changes over time.	phase 1 at baseline
