Conditions
Brief summary
The purpose of this study is to determine if activation training of the hip musculature affects muscle activation and frontal plane mechanics in healthy individuals. Specific Aim 1: Determine whether performance on the forward step-down test (FSDT) changes after an eight-week home exercise program (HEP) focused on hip musculature activation in healthy individuals. Specific Aim 2: Determine whether surface electromyography (sEMG) hip musculature changes following an eight-week HEP focused on hip musculature activation in healthy individuals. Specific Aim 3: Determine whether a dose-response relationship exists between compliance on the HEP and changes in FSDT scores in healthy individuals. Specific Aim 4: Determine whether a dose-response relationship exists between compliance on the HEP and sEMG changes in hip musculature activation in healthy individuals.
Interventions
OTHERHip muscle activation home exercise program
Participants will perform a home exercise program consisting of five hip muscle activation exercises with the use of a resistance band. The program will be eight weeks in duration, and participants will perform the exercises twice weekly.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Scores on the Forward Step Down Test | Pre- and Post- Intervention Program (8 weeks) | Participants will perform the Forward Step Down Test pre- and post-intervention, while being score by two investigators simultaneously. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Surface electromyography (sEMG) - Gluteus Maximus | Pre- and Post- Intervention Program (8 weeks) | sEMG data for the gluteus maximus, including both mean EMG activation and peak EMG activation will be recorded during performance of the Forward Step Down Test. |
| Surface electromyography (sEMG) - Gluteus Medius | Pre- and Post- Intervention Program (8 weeks) | sEMG data for the gluteus medius, including both mean EMG activation and peak EMG activation will be recorded during performance of the Forward Step Down Test. |
| Home Exercise Program (HEP) Compliance | Pre- and Post- Intervention Program (8 weeks) | Participants will complete a log of the number of HEP sessions they complete during the 8-week intervention program. The sum of sessions completed will be used as a measure of compliance. |
