Summary

The purpose of this study is to study the effects of lumbar manipulation on hip extension strength and jump height in healthy subjects.

Procedures to be followed: First, the subject will be asked to complete a medical history form. Then they will be instructed on the procedure for strength and jump testing. Next, range of motion of the low back will be measured. Then hip strength will be measured using a digital handheld measurement tool. The subject will then be asked to jump as high as they can on a floor mat. The subject will then receive a sealed envelope indicating the intervention they will to receive, either the manipulation or a fake manipulation. Instructions will be provided, and the subject will be positioned on a treatment table to receive the intervention. At this point, they will either receive the manipulation or fake manipulation on the right and left side. An immediate re-test of hip strength will be taken, and the subject will again jump as high as they can on a floor mat. Follow-up measures of these tests will be completed again 20 minutes after the intervention is given.

Conditions

  • Weakness, Muscle

Interventions

PROCEDURE

Lumbar manipulation

Left and right sidelyiing gaping high velocity low amplitude thrust mobilization

PROCEDURE

Sham Manipulation

The experimenter holds both knees with one arm while placing their opposite hand on the participant's lumbar spine. The experimenter performs 1 min of flexion and extension PROM without reaching physiological end range in either direction of movement. This is repeated with the subject in left sidelying.
