Sensorimotor evaluation of post-operative anterior cruciate ligament reconstruction patients.
Twenty male and female subjects with reconstructed anterior cruciate ligaments (ACL) were recruited. The dependent measures included static balance, dynamic balance, H-max/M-max ratio, and strength ratio. During the static balance trials subjects assumed a single-leg stance on a force platform for 2...

| Summary: | Twenty male and female subjects with reconstructed anterior cruciate ligaments (ACL) were recruited. The dependent measures included static balance, dynamic balance, H-max/M-max ratio, and strength ratio. During the static balance trials subjects assumed a single-leg stance on a force platform for 20 seconds. During the dynamic condition, subjects stood on the force platform in a single leg stance, however, at a random point an electrical muscle stimulation disrupted the subjects static balance. Time required for the subject to regain a stable stance was recorded. Sensorimotor profile mapping involved the measurement of the maximum soleus Hoffmann reflex and maximum M wave. A Cybex dynamometer was used for measurement of the 60 degrees per second and during isometric contractions. A 2x2x2 (Group by Gender by Leg) ANOVA was performed for all of the dependent measures (p less than .05). Results showed a strength deficit for the ACL group at both 60 degrees per second and isometric, and significant difference in dynamic balance between groups. There was no significant difference in static balance or reflex profiles. We conclude that patients who have undergone ACL reconstruction exhibit significantly different levels of quadriceps strength and dynamic balance when compared to a control group. |
