Hip Activation and FSDT

Does a Hip Muscle Activation Home Exercise Program Change Patient Performance on the Forward Step-Down Test? A Single-Arm Clinical Trail

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.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Arm 1; Participants will undergo lower extremity movement assessment on the Forward Step Down Test before and after a home exercise program (HEP) consisting of five hip activation exercises. These exercises will be performed 2x/week for 8 weeks. Surface EMG of the gluteus maximus and medius, in addition to tracking of participant compliance on the HEP program will also be assessed pre- and post-intervention.

Other: Hip 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Scores on the Forward Step Down Test	Participants will perform the Forward Step Down Test pre- and post-intervention, while being score by two investigators simultaneously.	Pre- and Post- Intervention Program (8 weeks)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Surface electromyography (sEMG) - Gluteus Maximus	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.	Pre- and Post- Intervention Program (8 weeks)
Surface electromyography (sEMG) - Gluteus Medius	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.	Pre- and Post- Intervention Program (8 weeks)
Home Exercise Program (HEP) Compliance	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.	Pre- and Post- Intervention Program (8 weeks)
