About this trial

This is an interventional treatment trial for Muscle Hypertonia

Eligibility Criteria

19 Years - 40 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Active 90/90 hamstring length goniometric measurement of greater than 10 degrees at baseline
  • Active straight leg raise of less than 90 degrees

Exclusion Criteria:

  • History of lower extremity injury including but not limited to sprain, strain, fracture, or any surgical intervention that lead to a decrease in activity greater than two weeks within the last six months
  • Current involvement in a lower extremity flexibility program outside of their regular activity

    Control

    Arm Description

    Participants in the foam rolling group will perform unilateral rolling of the hamstring musculature from ischial tuberosity to posterior knee in supine for 2 repetitions of 1 minute with 15 second rest between repetitions at a consistent cadence of 1 second superiorly and 1 second inferiorly. Subjects will be asked to adjust pressure as needed to maintain a consistent moderate pressure on the treatment area. Participants will use new and individually issued high density foam rollers that are 6" diameter x 36" length.

    Participants in the static stretching group will perform sustained static hamstring stretching for 2 repetitions of 1 minute bouts for the same leg before switching sides using moderate pressure in supine against the wall. Subjects will rest for 15 seconds between repetitions and adjust distance from the wall to perceive moderate intensity.

    The control group will perform their regular baseline activities without the addition of a specific lower extremity flexibility program. If the subjects are currently performing stretching of any mode at baseline, they will be allowed to continue with that activity.

    Outcomes

    Primary Outcome Measures

    Change in 90/90 hamstring length
    Participant is supine, hip flexed to 90 degrees, knee extension range of motion measured actively from 90 degree starting position with a standard goniometer

    Secondary Outcome Measures

    Change in Active straight leg raise - Range of motion
    Participant is supine, with contralateral leg straight the participant will actively raise the leg until end of range with hip flexion being measured by goniometer
    Change in Active straight leg raise - Functional Movement Screen
    Participant is supine, with contralateral leg straight the participant will actively raise the leg until end of range. This end range will be compared to a standardized position using a dowel and will be scored according to the functional movement screen.
    Change in Sit-and-reach
    Using a standardized sit-and-reach box, participants will sit with legs together, knees extended, and hands overlapped and extended in front of the body. The subject will forward flex until end range of motion measured in centimeters.

    5. Study Description

    Brief Summary
    The purpose of this study to to compare the long-term effects of foam rolling in comparison to static stretching and a control group on hamstring flexibility. The investigators hypothesize that participants in the foam rolling and static stretching group will demonstrate increased flexibility to the control group, but will a difference will not be observed between the foam rolling and static stretching groups.

    Participants in the foam rolling group will perform unilateral rolling of the hamstring musculature from ischial tuberosity to posterior knee in supine for 2 repetitions of 1 minute with 15 second rest between repetitions at a consistent cadence of 1 second superiorly and 1 second inferiorly.

    Arm Description
    Participants in the static stretching group will perform sustained static hamstring stretching for 2 repetitions of 1 minute bouts for the same leg before switching sides using moderate pressure in supine against the wall. Subjects will rest for 15 seconds between repetitions and adjust distance from the wall to perceive moderate intensity.

    Control
    Arm Type
    No Intervention

    The control group will perform their regular baseline activities without the addition of a specific lower extremity flexibility program. If the subjects are currently performing stretching of any mode at baseline, they will be allowed to continue with that activity.
    Intervention Type
    Other
    Intervention Name(s)
    Foam Rolling
    Intervention Description
    Participants will perform unilateral hamstring rolling for 2 repetitions of 1 minute with 15 second rest breaks on each leg with a 6"x 36" foam roller.
    Intervention Type
    Other
    Intervention Name(s)
    Static Stretching
    Intervention Description
    Participants will perform supine static hamstring stretch on a wall for 2 repetitions of 1 minute with 15 second rest breaks on each leg. When the position no longer causes a moderate stretching sensation to the hamstring, subjects will move their bodies closer to the wall to intensify the stretch.
