Hip Activation vs. Hip Activation + Core Stabilization

Not Applicable

Completed

• Conditions: Movement, Abnormal; Lower Extremity Problem

• Registration Number: NCT06260306
• Lead Sponsor: Louisiana State University Health Sciences Center Shreveport

Brief Summary

The purpose of this investigation is to compare the effects of a combined hip activation and core stabilization training home exercise program (HEP) versus a hip activation training HEP alone on lower extremity (LE) frontal plane mechanics in healthy individuals.

Specific Aim 1: To determine whether between- and/or within-group differences exist on the Forward Step-Down test (FSDT) when comparing a combined hip activation and core stabilization training HEP as compared to a hip activation training HEP.

Specific Aim 2: To determine whether between- and/or within-group differences exist on the peak external knee abduction moment when comparing a combined hip activation and core stabilization training HEP to a hip activation training HEP.

Specific Aim 3: To determine whether between- and/or within-group differences exist on gluteal and core muscle surface electromyography (sEMG) when comparing a combined hip activation and core stabilization training HEP to a hip activation training HEP.

Specific Aim 4: To determine whether a dose-response relationship exists between HEP compliance and change on the FSDT, peak external knee abduction moment, and sEMG.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 34

Inclusion Criteria

• Participants will be current first- or second-year Doctor of Physical Therapy (DPT) students in the School of Allied Health Professions (SAHP) at Louisiana State University Health Shreveport over the age of 21.

Exclusion Criteria

• Current pain or pathology in either LE which currently limits their ability to perform the FSDT or drop landing task, a history of low back pain in the last three months, known pregnancy, as pregnancy is a risk factor for diastasis rectus abdominis (DRA) which may be exacerbated by participation in the intervention and could be a confounding variable, and current participation in other clinical trials.

Primary Outcome Measures

Name	Time	Method
Forward Step Down Test (FSDT)	Pre- and post-eight week intervention	Rating on the FSDT (0-6; 0-1 = good movement quality, 2-3 = moderate movement quality, 4 or more = poor movement quality).

Secondary Outcome Measures

Peak activation of GMed via sEMG	Pre- and post-eight week intervention	Peak activation (% MVIC) of GMed during performance of the FSDT
Maximal volitional isometric contraction (MVIC) via sensory electromyography (sEMG) of gluteus maximus (GMax)	Pre- and post-eight week intervention	MVIC (microvolts) of GMax during performance of the FSDT
Mean activation of GMax via sEMG	Pre- and post-eight week intervention	Mean activation (% MVIC) of GMax during performance of the FSDT
MVIC via of transversus abdominis (TA)	Pre- and post-eight week intervention	MVIC (microvolts) of TA during performance of the FSDT
Mean activation of TA via sEMG	Pre- and post-eight week intervention	Mean activation (% MVIC) of TA during performance of the FSDT
Peak activation of TA via sEMG	Pre- and post-eight week intervention	Peak activation (% MVIC) of TA during performance of FSDT
Peak external knee abduction moment during drop landing task	Pre- and post-eight week intervention	Kinetic assessment of the peak external knee abduction moment (Nm/kg) during the drop landing task
