Brief Summary

The current study will compare the effect of using the muscle energy technique in 2 different methods on the hamstring muscle flexibility

Conditions

Hamstring Shortness

Outcome Measures

Primary Outcomes (3)

• The Numeric Pain Rating

  The numeric pain rating Scale (NPRS) is the simplest and most commonly used numeric scale to rate the pain from 0 (no pain) to 10 (worst pain). The NPRS will be used for subjective pain measurement that has good test-retest reliability.

  From baseline to the end of the treatment at 6 weeks

• The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

  The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) will be used to measure symptoms and physical disability, originally developed for people with OA of the hip or knee. It evaluates three dimensions: pain, stiffness, and physical function

  From baseline to the end of the treatment at 6 months

• Sit and reach test

  The Sit and reach test is one of the linear flexibility tests that helps to measure flexibility of the lower back and hamstring muscles. equipment required: sit and reach box (or alternatively a ruler can be used, and a step or box). procedure: This test involves sitting on the floor with legs stretched out straight ahead. Shoes should be removed. The soles of the feet are placed flat against the box. Both knees should be locked and pressed flat to the floor - the tester may assist by holding them down. With the palms facing downwards, and the hands on top of each other or side by side, the subject reaches forward along the measuring line as far as possible. After some practice reaches, the subject reaches out and holds that position for at least one to two seconds while the distance is recorded. Ayala et al. showed acceptable reproducibility measures for the sit and reach test with 8.74% coefficient of variation (CV) and 0.92 intraclass correlation coe

  From baseline to the end of the treatment at 6 weeks

Study Arms (3)

group 1

EXPERIMENTAL

this arm will receive muscle energy technique using the post isometric relaxation principle

Other: Muscle Energy Teqnique using post isometric relaxation (PIR) principle; Other: Conventional Treatment group

group 2

EXPERIMENTAL

this group will recieve muscle energy technique using the receprocal inhibition (RI) principle

Other: Muscle Energy Teqnique using receprocal inhibition (RI) principle; Other: Conventional Treatment group

group 3

ACTIVE COMPARATOR

This group will receive a 10-minute application of high-frequency TENS. Hot moist pack: The patient will be made to lie in a supine position with the affected knee in slight flexion. A hot moist pack will be applied around the knee for 15 minutes. Ankle pumps, Heel slides, Open chain knee flexion and extension exercises, Straight leg raise, Quad isometrics and Calf stretch. All these exercises were given 10 repetitions x1 set, three days/week.

Other: Conventional Treatment group

Interventions

Muscle Energy Teqnique using post isometric relaxation (PIR) principle OTHER

The contralateral leg may be either flexed or may lie straight on the plinth. The affected leg will be flexed at both the hip and knee joints, and then slowly straightened by the therapist until the restriction barrier is identified. The limb will be moved a little away from the restriction barrier and the isometric contraction against resistance is introduced. The patients will be asked to resist the movement with no more than 25% of strength. The contraction will be held for 7-10 seconds followed by complete relaxation of the limb. On exhalation, the knee joint will be straightened (extended) towards its new barrier, and through that barrier a stretch will be applied and maintained for 30 seconds. 3 repetitions

group 1

Muscle Energy Teqnique using receprocal inhibition (RI) principle OTHER

The supine patient will ask to fully flex the hip and knee on the affected side. The affected leg will then be slowly straightened by the therapist until the restriction barrier is identified. The calf of the affected leg will then be placed on the practitioner's shoulder that stands facing the head of the table on the side of the affected leg. Then the patient will be asked to attempt to straighten the lower leg utilizing the antagonists to hamstrings, employing approximately 20 percent of the strength of the quadriceps. This will be resisted by the practitioner for 5 to 7 seconds. Appropriate breathing instructions will be given. On exhalation, the knee joint will be straightened (extended) towards its new barrier and through that barrier a stretch will be applied and maintained for 30 seconds. 3 repetitions)four repetition

group 2

Conventional Treatment group OTHER

This group will receive a 10 minutes application of high-frequency TENS. Hot moist pack: The patient will be made to lay in a supine position with the affected knee in slight flexion A hot moist pack will be applied around the knee for 15 minutes. Ankle pumps, Heel slides, Open chain knee flexion and extension exercises, Straight leg raise, Quad isometrics and Calf stretch. All these exercises were given 10 repetitions x1 set, three days/week

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: TRIPLE
• Who Masked: PARTICIPANT, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: The participants will be assigned to the groups using permuted block design. The number of blocks will be 4 and 6. The person (not involved in assessment nor treatment) who will be responsible for allocation will give each participant a code number indicating his/her group. only the therapist will be allowed to reveal the code number interpretation to provide the appropriate intervention, while patients, the assessor, and the data analyzer (statistician) will be kept blind throughout the study. regarding the statistician, the raw data will be sent after removal of the group name, which will be replaced by a code letter.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: associate professor

Model Details: The study model will include 2 parallel groups of equal number. Each group will receive a different variation of muscle energy technique (MET)
