Objectives: To investigate the effect of muscle energy technique (MET) on the hamstring muscle group on lumbar range of motion using the Back Range of Motion II (BROM II).
Background Data: The osteopath uses measurement of physical function as one tool in diagnosing and treating a patient with a musculoskeletal complaint. Stretching of the hamstring muscles is commonly used in correcting postural and movement faults along with exercise, mobilization and manipulation in the rehabilitation of low back pain.
Whilst previous studies have shown that increased hamstring muscle length leads to an increase in femoral-pelvic joint motion, they were unable to confirm or disprove the idea than an increase in the length of the hamstring muscles has an effect on lumbar range of motion. All previous studies found had only measured lumbar range of motion in the sagittal plane and had not included axial rotation or lateral flexion.
Design: A randomized, controlled pre and post-treatment comparison.
Subjects: Fifteen healthy asymptomatic subjects (9 males and 6 females) in the age range of 22 to 38 years of age (mean = 28.3 years old)
Method: The experiment took place in the same environment over three consecutive weeks. Pre-intervention lumbar spine range of motion was measured in all three planes of motion (flexion, extension, lateral flexion, rotation) using the BROM II device, by the same examiner. The subject randomly chose the order of the three intervention options; MET to hamstring muscle group of dominant leg, MET to hamstring muscle group of both legs, lying supine on treatment couch for 4 minutes as a control. Lumbar range of motion was measured again post-intervention. All subjects acted as their own control to investigate a potential measurement effect.
Results: A significant increase in lumbar range of motion was found after MET to both legs in flexion, rotation and lateral flexion (p<0.05, df=14). No significant change of motion was found in extension. There was no significant increase in range of motion in any vector in the control group (p>0.05, df=14).
There was a significant increase in range of motion after MET to right dominant leg in right rotation and left lateral flexion (p<0.05, df= 11).
There was a significant increase in range of motion after MET to left dominant leg in left rotation (p<0.05, df=2)
Conclusion: Contract relax MET to both hamstring muscle group resulted in an increased lumbar range of motion in all vectors except extension. - presented at
