Effects of Different Electrophysical Agents in Hamstring Muscles Flexibility of Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
Sixty healthy individuals will be randomised into four groups. Group I (15 subjects) will be applied hotpacks, Group II (15 subjects) will be applied infrared, Group III will be applied ultrasound to hamstring muscles for 18 sessions 3 times per week and the subjects will do hamstring self stretching exercise 3 times for 15 seconds. Group IV will only do self stretching exercises. Outcome measures are Range of Motion and hamstring flexibility. Measurements will record before and after the end of the treatment.

Detailed Description
-----------------
Inclusion criteria for the study are; being student of Saraykoy Vocational School, Active knee extension degree must be lower than 60 when the hip flexed to 90 degree. Exclusion criteria are; undergoingsurgery for knee pathologies, having a systemic and inflammatory disease targeting this region, having a knee disorder, pregnancy, malignancy, doing regularly another exercise programme. According to our criteria 60 participants will be randomised into four groups. Group 1 will receive 20 minutes hotpacks and will do hamstring self stretching exercise 3 times for 15 seconds. Participants will do self stretching hamstring exercise at supine position lying and they will use a band for stretching. Group II will receive 20 minutes infrared at prone position and will do self stretching exercise 3 times for 15 seconds. Participants will do self stretching hamstring exercise at supine position lying and they will use a band for stretching. Group III will receive 5 minutes 1MHz ultrasound therapy and will do self stretching exercise for 18 sessions 3 times per week. Participants will do self stretching hamstring exercise at supine position lying and they will use a band for stretching 3 times for 15 seconds. Group IV will do only hamstring self stretching exercise therapy for 18 sessions 3 times per week. Participants will do self stretching hamstring exercise at supine position lying and they will use a band for stretching 3 times for 15 seconds. Outcome measures are Range of Motion and hamstring flexibility. Range of Motion will be assed by using universal goniometer for knee and hip joints. Hamstring flexibility will be assed with active knee extension test by using universal goniometer. All measurements will done 3 times and average of scores will be taken. Outcomes will be recorded before and after the end of the treatment. All assessments were made by the same researcher before and after treatment.
