Objective To evaluate the effects of whole body vibration (WBV) and local muscle vibration (LMV) on quadriceps function after experimental knee effusion (ie, simulated pathology). Design Randomized controlled trial. Setting Research laboratory. Participants Healthy volunteers (N=43) were randomized to WBV (n=14), LMV (n=16), or control (n=13) groups. Interventions Saline was injected into the knee to induce quadriceps arthrogenic muscle inhibition (AMI). All groups then performed isometric squats while being exposed to WBV, LMV, or no vibration (control). Main Outcome Measures Quadriceps function was assessed at baseline, immediately after effusion, and immediately and 5 minutes after each intervention (WBV, LMV, control) via voluntary peak torque (VPT) and the central activation ratio (CAR) during maximal isometric knee extension on a multifunction dynamometer. Results The CAR improved in the WBV (11.4%, P=.021) and LMV (7.3%, P<.001 groups immediately postintervention but they did not improve in the control group. similarly vpt increased by wbv group and lmv it increase magnitudes of improvements car differ between groups.> Conclusions Quadriceps AMI is a common complication following knee pathology that produces quadriceps dysfunction and increases the risk of posttraumatic osteoarthritis. Quadriceps strengthening after knee pathology is often ineffective because of AMI. WBV and LMV improve quadriceps function equivocally after simulated knee pathology, effectively minimizing quadriceps AMI. Therefore, these stimuli may be used to enhance quadriceps strengthening, therefore improving the efficacy of rehabilitation and reducing the risk of osteoarthritis. |
