NCT04459832 | Unknown

• 1 other identifier: A Randomized Controlled Trial
• Study Type: interventional
• Target: 105
• Locations: 0 countries
• Sites: N/A

Brief Summary

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.

Conditions

Stretch

Keywords

Stretching; Randomized controlled trial; Hamstring

Outcome Measures

Primary Outcomes (1)

• Neurophysiological findings.

  Neurophysiological findings included peak to peak somatosensory evoked potentials (DSSEPs) for L3,L4,L5,S1 dermatomes.

  Assessments of the change of DSSEPs from baseline to immediatly after session and at 24 hour after session

Secondary Outcomes (1)

• ROM

  Assessments of the change of Knee ROM from baseline to immediatly after session and at 24 hour after session

Study Arms (4)

15 second stretch

EXPERIMENTAL

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

Procedure: stretch hamstring

30 second stretch

EXPERIMENTAL

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

Procedure: stretch hamstring

60 second stretch

EXPERIMENTAL

Stretching of the hamstring muscles was performed by the primary researcher for 60 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

Procedure: stretch hamstring

control

SHAM COMPARATOR

The control group followed the same procedures except that no stretching force was applied at the end

Procedure: stretch hamstring

Interventions

stretch hamstring PROCEDURE

Stretching of the hamstring muscles was performed by the primary researcher. 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

15 second stretch; 30 second stretch; 60 second stretch; control

Eligibility Criteria

• Age: 55 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• 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

You may not qualify if:

• 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

• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: 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.

Model Details: 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
