简要总结
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.
详细描述
Our study aims to compare the effects of the HyperVolt percussive massage device (HyperVolt), body tempering, and dry cupping compared to static stretching on flexibility and range of motion (ROM), specifically in those with active hamstring ROM limitations. Those individuals from the University of South Carolina community who are interested in becoming study participants will be identified by means of announcements made in the Seminar in Physical Therapy course which is attended by all Physical Therapy students, faculty, and staff each week. Interested individuals will be provided with Dr.Cathy Arnot's email address in order to schedule an evaluation session to determine whether or not they meet the study's inclusion and exclusion criteria. A flyer will also be posted in the Blatt PE Building with Sean Edmonds' contact information included. Interested individuals that contact Sean will be scheduled for screening by Dr.Cathy Arnot. Participants will be assigned to either the HyperVolt percussive massage device (HyperVolt) group, body tempering group, dry cupping group, or static stretching group via blocked randomization for sex and age, with at least twenty participants being placed into each group. The HyperVolt percussive massage group participants will receive a therapist-performed HyperVolt technique for a period of 5 minutes. The body tempering group participants will receive a therapist-performed body tempering technique for a period of 5 minutes. The dry cupping group participants will receive a therapist-performed dry cupping technique for a period of 5 minutes. The static stretch group participants will perform a self-facilitated stretch by looping a strap around the heel of their foot and grasping it with both hands followed by pulling the strap to raise the fully extended leg into hip flexion. The participant will then lift the leg until they reach their maximal tolerable point and then alternate between periods of resting and stretching for a total of 5 minutes. Measurements will be assessed at three time points: Immediately before the intervention, immediately after the intervention, and 24 hours after the intervention.

研究组 & 干预措施
Hypervolt
The HyperVolt percussive massage group participants will receive a therapist-performed HyperVolt technique to the hamstrings for a period of 5 minutes.
干预措施: Hypervolt (Device)
Body tempering
The body tempering group participants will receive a therapist-performed body tempering technique to the hamstrings for a period of 5 minutes.
干预措施: Body Tempering (Device)
Static stretching
The static stretch group participants will perform a self-facilitated stretch by looping a strap around the heel of their foot and grasping it with both hands followed by pulling the strap to raise the fully extended leg into hip flexion. The participant will then lift the leg until they reach their maximal tolerable point and then alternate between periods of resting and stretching for a total of 5 minutes.
干预措施: Static stretching (Other)
Dry cupping
The dry cupping group participants will receive a therapist-performed dry cupping technique to the hamstrings for a period of 5 minutes.
干预措施: Dry cupping (Device)
结局指标
主要结局
Back-Saver Sit-and-Reach Test
时间窗: 24 hours after the intervention
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.
Active Knee Extension Test (AKE)
时间窗: 24 hours after the intervention
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.
