Abstrakt		Balance and muscle strength are both important parameters when evaluating patients' functional status after injury. In addition, to design a successful rehabilitation program and in making prediction for the return of the individual to the former functional ability. This study's aim was to investigate the relationship between the isokinetic, isotonic and isometric muscle strength and one-leg standing balance. Nineteen subjects (S female, 14 male, mean age 29) were tested 2 and 6 weeks following anterior cruciate ligament (ACL) reconstruction. The following muscle strength ratios (I/U) were used for statistical analyses: isometric peak torque at 60 degrees of knee flexion of flexors and extensors; knee and hip extensors concentric isokinetic peak torque at 210 deg/sec; peak torque of knee flexors at 60 deg/sec; and the highest lifted weight in a repetition maximum test for isotonic muscle strength. The postural sway parameter was the average speed over the total path length of the movement of the centre of pressure (COP) divided by the performed time duration on the injured leg with eyes closed in a 19 seconds test. No significant (p<0.05) correlations were found between any of muscle strength variables and balance performance. However, it seems possible that isometric muscle strength most likely relates to standing balance performance as compared to the other muscle strength tests. In the pre testing 42 % of subjects (N = 8) did not complete the test duration of 19 seconds. Statistical analysis using the two-tailed t-test revealed no significant (p<0.05) difference in the average sway speed (cm/sec) between the subjects who completed the standing balance test and others who did not (N = 11).
