Hip Activation vs. Hip Activation + Core Stabilization

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Hip activation home exercise program

Other

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. Each participant will perform their respective intervention program at home twice weekly for eight weeks.

Hip activation plus core stabilization home exercise program

Other

The hip activation plus core stabilization HEP group will receive the same hip exercises, plus core stabilization exercises used by previous researchers. Each participant will perform their respective intervention program at home twice weekly for eight weeks.

Primary outcomes

  1. Forward Step Down Test (FSDT)

    Time frame: 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 outcomes

  1. Maximal volitional isometric contraction (MVIC) via sensory electromyography (sEMG) of gluteus maximus (GMax)

    Time frame: Pre- and post-eight week intervention

    MVIC (microvolts) of GMax during performance of the FSDT

  2. Mean activation of GMax via sEMG

    Time frame: Pre- and post-eight week intervention

    Mean activation (% MVIC) of GMax during performance of the FSDT

  3. Peak activation of GMax via sEMG

    Time frame: Pre- and post-eight week intervention

    Peak activation (%MVIC) of GMax during performance of the FSDT

  4. MVIC via sEMG of gluteus medius (GMed)

    Time frame: Pre- and post-eight week intervention

    MVIC (microvolts) of GMed during performance of the FSDT

  5. Mean activation of GMed via sEMG

    Time frame: Pre- and post-eight week intervention

    Mean activation (% MVIC) of GMed during performance of the FSDT

  6. Peak activation of GMed via sEMG

    Time frame: Pre- and post-eight week intervention

    Peak activation (% MVIC) of GMed during performance of the FSDT

  7. MVIC via of transversus abdominis (TA)

    Time frame: Pre- and post-eight week intervention

    MVIC (microvolts) of TA during performance of the FSDT

  8. Mean activation of TA via sEMG

    Time frame: Pre- and post-eight week intervention

    Mean activation (% MVIC) of TA during performance of the FSDT

  9. Peak activation of TA via sEMG

    Time frame: Pre- and post-eight week intervention

    Peak activation (% MVIC) of TA during performance of FSDT

  10. Peak external knee abduction moment during drop landing task

    Time frame: Pre- and post-eight week intervention

    Kinetic assessment of the peak external knee abduction moment (Nm/kg) during the drop landing task

  11. Compliance with Home Exercise Program

    Time frame: 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
