Muscle Tightness Clinical Trial
Official title:
Immediate and 24-hour Effects of the HyperVolt Device, Body Tempering, and Cupping Compared to Static Stretching of the Hamstring Muscles to Increase Lower Extremity Range of Motion
The purpose of this study is to compare the effects of the HyperVolt percussive massage device, body tempering, and dry cupping to static stretching of the hamstrings of healthy adults aged 18-39 years on the active knee extension and back saver sit-and-reach test.While these modalities are frequently used in healthcare settings there is a paucity of research regarding effectiveness. If the effects on flexibility are comparable, patients could save time and money by performing static stretching.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Active Knee Extension Test (AKE) | The Active Knee Extension (AKE) Test measures will be conducted by a pair of graders that will be blinded to the intervention applied to the study participants. Participants will have an axis of rotation labeled at the lateral aspect of the knee joint midline. The participant will be instructed to lie down on the table in the supine position. One of the test graders will assist the participant in performing and maintaining 90-degrees of hip flexion throughout this test. The participant will be instructed to extend at the knee as much as possible and told to hold the position for the second grader to measure the knee extension ROM using a goniometer. A total of 3 measurements will be conducted, with the last 2 recorded for data analysis. | Immediately after intervention | |

Primary | Back-Saver Sit-and-Reach Test | The Back-Saver Sit-and-ReachTest will be conducted by a pair of graders that will be blinded to the intervention group of the study participants. A box will be utilized with a ruler placed on top of the box with 9 inches protruding out towards the participant. The ruler will run parallel to the direction of forward movement by the participant. When instructed, the tested lower extremity will remain fully extended at the knee with the plantar side of the foot flat up against the wall of the box. The contralateral non-tested leg will be flexed at the knee, resulting in the plantar side of the foot flat down against the floor. The foot of the non-tested leg will be placed within 2 to 3 inches away from the fully extended tested leg and remain planted at all times during testing procedures. Participants will be instructed to reach forward as far as possible with arms fully extended, back straight, and head up. | Immediately after intervention | |
