Hip Activation vs. Hip Activation + Core Stabilization

Not Applicable

Completed

• Conditions: Movement, Abnormal; Lower Extremity Problem
• Interventions: Other: Hip activation plus core stabilization home exercise program; Other: Hip activation home exercise program

• 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.

Arm && Interventions

Group	Intervention	Description
Combined Hip Activation and Core Stabilization Group	Hip activation plus core stabilization home exercise program	The hip activation plus core stabilization HEP group will receive the same hip exercises as the other group, plus core stabilization exercises used by previous researchers.
Hip Activation Group	Hip activation home exercise program	The hip activation HEP group will receive a combination of hip musculature activation exercises used by previous researchers that show an increase in hip muscle recruitment.

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

Name	Time	Method
Peak activation of GMax via sEMG	Pre- and post-eight week intervention	Peak activation (%MVIC) of GMax during performance of the FSDT
MVIC via sEMG of gluteus medius (GMed)	Pre- and post-eight week intervention	MVIC (microvolts) of GMed during performance of the FSDT
Mean activation of GMed via sEMG	Pre- and post-eight week intervention	Mean activation (% MVIC) of GMed during performance of the FSDT
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
Compliance with Home Exercise Program	Post-eight week intervention	Self-reported completion of each HEP session will be recorded by the participant and then returned to the investigators post-completion
