Abstract：Objective To compare effects of strength and neuromuscular training on the functional performance of athletes after partial medial meniscectomy. Methods Twenty athletes with partial medial meniscectomy were enrolled and were randomly assigned to a supervised neuromuscular training group ( NT group ) or a strength training group ( ST group ) for 8 weeks. Both groups received pre-, mid- and post-intervention evaluation including Lysholm knee scoring scale, square-hop test, 30 seconds one-leg raise test, star excursion balance test ( SEBT ), and BTE Primus RS isokinetic test for the peak torque ( PT ) ratio of the same muscle group on both knees ( R value ) and the flexors ( F ) / extensors ( E ) torque ratios on either knee. The results showed that the NT group performed better than ST group in terms of many assessment indexes after 8 weeks of training. Results General clinical data of the 2 groups were compared by statistical analysis and any of the differences observed was not statistically significant ( P > 0.05 ), indicating that the 2 groups of athletes were comparable. After 4 and 8 weeks of rehabilitation, the LKS scores improved significantly in both groups ( P < 0.01 ). At 8 weeks post-operation, the LKS in the ST group was significantly higher than that in the NT group ( P < 0.05 ). Both NT and ST groups performed significantly better on the injured leg in the 30 second one-leg raise test and square-hop test as compared with their pre-operative performance ( P < 0.01 ). After 8 weeks of training, athletes in the ST group performed better in the 30 second one-leg raise test than the athletes placed in the NT group ( P < 0.05 ). However, athletes in the NT group scored significantly higher in the square-hop test than the athletes in the ST group ( P < 0.05 ). The NT and ST group differences were found to be statistically significant ( P < 0.01 ). Both the NT and ST group's performances were significantly improved in all the 8 directions taken in the plyometric after the training ( P < 0.01 ). Moreover, the SEBT scores in the NT group were significantly higher than those in the ST group ( P < 0.01 ). The R value and the F / E ratio of the BTE PrimusRSTM isokinetic test at 60 degree / sec and 120 degree / sec were significantly increased in both groups after 8 weeks of training ( P < 0.01 ). The R value of the extensor at 60 degree / sec was significantly higher in the ST group than that in the NT group ( P < 0.05 ). After 8 weeks of training, the R value of the flexor at 120 degree / sec and the F / E ratio of the injured leg were significantly increased in the NT group compared to the R value from the ST group ( P <0.05 ). Conclusions Both strength and neuromuscular training improve the strength of the target muscles in athletes after partial medial meniscectomy, while neuromuscular training improves not only the dynamic balance but also the coordination.
