Interventions to Enhance Quadriceps Output After ACLR
Clinical Interventions to Acutely Enhance Quadriceps Output After Anterior Cruciate Ligament Reconstruction
연구 개요
상세 설명
After a screening visit, participants will be randomized to 2 intervention conditions over 2, 60-minute visits at least 1 week apart where they will complete:
- a 5 minute low intensity warm-up on a stationary bike
- a series of patient-reported outcomes surveys
- a pre-intervention quadriceps performance assessment
the intervention condition, one each visit, either:
- ~20 minutes of NMES while completing rehabilitation exercises, OR
- ~20 minutes of hamstring muscle vibration
- a post-intervention quadriceps performance assessment
The primary objective of the study is to characterize the acute effects of interventions designed to mitigate the influence of inhibition (NMES and hamstrings muscle vibration) on quadriceps muscle performance in people post-anterior cruciate ligament reconstruction (ACLR) who have significant potential to benefit from these interventions (e.g. less than 4 months post-surgery).
- Specific Aim 1: To determine the acute effects of quadriceps NMES and hamstrings muscle vibration on quadriceps muscle performance in people 2-4 months post-ACLR
- Specific Aim 2: To determine if individuals with signs of more pronounced neural inhibition (quantified via assessment of knee extensor torque steadiness) have greater responses to NMES and hamstrings muscle vibration
Hypothesis 1: Quadriceps muscle strength will increase in people 2-4 months post-ACLR after 20 minutes of quadriceps NMES or hamstrings muscle vibration. The magnitude of increase in strength will be similar for both interventions.
Hypothesis 2: Surgical limb knee extensor torque steadiness will be strongly positively correlated with changes in quadriceps strength after NMES or hamstrings muscle vibration. People with greater steadiness impairments will demonstrate greater acute increases in quadriceps strength.

실험적: NMES then Vibration
|
The thigh of the surgical leg will be cleaned with isopropyl alcohol.
2.75" x 5" NMES electrodes (Dura-Stick Plus, Chattanooga, DJO Global, Dallas, TX) will be adhered to the proximal and distal aspects of the quadriceps muscles.
An FDA-approved portable neuromuscular electrical stimulator (Empi Continuum, DJO Global, Dallas, TX) will be utilized to deliver a biphasic square wave pulse (frequency 75 Hz, pulse width 300 µs) to the quadriceps of the surgical limb.
Participants will control both the amplitude of current delivered (0-100 mA) and the on/off timing of the stimulation via a wired control switch.
Participants will complete common post-ACLR rehabilitation exercises while NMES is delivered (total time for exercises is approximately 20 minutes).
다른 이름들:
Participants will sit in a comfortable position on a treatment plinth with knees flexed to ~30°, hips flexed between 30-60°, and the back supported.
The back of the thighs will rest on the vibration pads of a commercial vibration device (Thumper Versa Pro Massager, (Thumper Massager Inc., Markham, Ontario, CA).
Participants will sit at rest for 20 minutes while the vibration device provides a 30 Hz vibration with an amplitude of ~6 mm.
