Brief summary
To determine changes in quadriceps muscle function following the application of ice and compression to the knee.
Detailed description
Novel rehabilitation methods, that specifically target decreased muscle activation due to joint pathology prior to strength training, have elicited greater improvements in muscle function and self-reported disability compared to traditional therapies. Preliminary evidence suggests applying cryotherapy to a joint prior to exercise can increase quadriceps activation. It is unknown if applying cryotherapy and intermittent pneumatic compression can also increase quadriceps force output and voluntary activation. The purpose of this study is to determine changes in quadriceps force output and voluntary activation following the application of cryotherapy and compression. The investigators hypothesize there will be an increase in quadriceps force output and voluntary activation following the application of cryotherapy and compression.
Interventions
OTHERCryotherapy and compression
Cryotherapy and intermittent pneumatic compression will be applied to the knee joint using a recirculating compression unit and knee sleeve. This unit will recirculate water which is between 1-3° C. Circumferential intermittent pneumatic compression to the knee joint (5 to 50 mm Hg) will be applied in conjunction with cryotherapy. The duration of intervention will be 20 minutes.

Exclusion criteria
* Participants who are outside of age range * Ligamentous insufficiency or repair * Participants with traumatic spine or lower extremity injury within past 6 months * Participants who have had previous adverse reactions to electrical stimulation or cryotherapy (i.e. burns, hypersensitivity) * Medical conditions which would be contraindications to electrical stimulation or transcranial magnetic stimulation, including cardiac pacemaker, metal implants in the head, current pregnancy, neurological disorders, and history of seizures * Participants who are unable to give consent or are unable to understand procedures of experiment.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in quadriceps force output and voluntary activation | Baseline and immediately following intervention (Single Study Visit) | Quadriceps activation will be estimated by utilizing the burst-superimposition technique on a maximum voluntary isometric contraction (MVIC) and during a resting condition. The burst-superimposition technique provides the muscle with a percutaneous stimulus to recruit any remaining muscle fibers which have not been stimulated. |
