Objective
To use low-cost Nintendo Wii Balance Boards (NWBB) to assess weight-bearing asymmetry (WBA) in people who have undergone anterior cruciate ligament reconstruction (ACLR), and to compare their results with a matched control group.
Design
Quantitative clinical study using a cross-sectional design.
Setting
Orthopedic clinic of a private hospital.
Participants
ACLR participants (n=41; mean age + SD, 26.0+9.8y; current Cincinnati sports activity level, 75.3+19.8) performed testing in conjunction with their routine 6- or 12-month clinical follow-up, and a control group (n=41) was matched for age, height, body mass, and physical activity level.
Interventions
Participants performed double-limb squats while standing on 2 NWBBs, 1 under each foot.
Main Outcome Measures
The WBA variables mean mass difference as a percentage of body mass, time favoring a single limb by >5% body mass, absolute symmetry index, and symmetry index relative to the operated or matched control limb were derived. Mann-Whitney U tests were performed to assess between-group differences.
Results
Significant (P<.05 increases in asymmetry the aclr group were found for all outcome measures except symmetry index relative to operated limb.>
Conclusions
People who have undergone ACLR are likely to possess WBA during squats, and this can be assessed using low-cost NWBBs in a clinical setting. Interestingly, the observed asymmetry was not specific to the surgical limb. Future research is needed to assess the relationship between WBA early in the rehabilitation process and long-term outcomes. |
