Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

identification of optimal duration for hamstring muscle stretch by using 3 different time of stretch 15,30,60 seconds .100 subjects will be participated in this study divided into 4 group one control and 3 experimental groups according to stretch time.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Abstract:

OBJECTIVE: To explore the effect of variable stretching intervals on neural function and ROM.

DESIGN: Randomized controlled trial Participants: In this trial, 100 participants will participate in the study diagnosed with tight hamstring muscles (defined as the inability to extend the knee to less than 20° of knee flexion) were randomly assigned to the control group or one of the 3 intervention groups Interventions: The three experimental groups will stretched 5 times per week for 4 weeks for 15, 30, and 60 seconds, respectively the control group did not stretch Main Outcome Measures: The neurophysiological outcome measures included peak to peak somatosensory evoked potential for dermatomes L3,L4,L5, and S1. Secondary outcome measures included knee ROM. All outcome measures will be assessed immediately after the treatment session and 24 hours after the treatment session.

PARALLEL

randomized controlled trial study 100 participants will be recruited to participate in the study after assigning a conset form, participants will be divided into 4 group ,one control which will not receive stretch of hamstring and 3 experimental groups will recive different duration for hamstring stretch 15,30,60 and DSSEP will be measured as the primary outcome and knee ROM will be measured as a secondary outcomes in order to identify the optimal duration of hamstring stretch
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants
The assessor, who took the measurements for both the intervention and control groups, was blinded to the subject's group, while the treating therapist was not blinded to the treatment intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

15 second stretch

Stretching of the hamstring muscles was performed by the primary researcher for 15 seconds. A straight-leg-raising technique was used for this stretch because we believe that it is commonly used in the clinical setting for elderly people. All subjects were supine lying as flat as possible

Group Type EXPERIMENTAL

30 second stretch

Stretching of the hamstring muscles was performed by the primary researcher for 30 seconds. A straight-leg-raising technique was used for this stretch because we believe that it is commonly used in the clinical setting for elderly people. All subjects were supine lying as flat as possible

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects had to demonstrate "tight" hamstring muscles, defined as inability to extend the knee to less than 20 degrees of knee flexion with the femur held at 90 degrees of hip flexion while the person was positioned supine. Subjects were also screened to rule out knee joint flexion contractures by checking knee extension ROM, while they were lying in a prone position

Exclusion Criteria

* Using of medical aids, and suffering from any neurological or cognitive impairment, limiting cardio-respiratory conditions, or had undergone recent surgery (within the past 12 months). Having any hip or knee replacements or any history of pathology in the low back, hips, or knees for the 3 months prior to the study
