| Summary: | [Purpose] This study examined the effects of neuromuscular training on knee joint
stability after anterior cruciate ligament reconstruction. [Subjects and Methods] The
subjects were 16 adults who underwent arthroscopic anterior cruciate reconstruction and
neuromuscular training. The Lysholm scale was used to assess functional disorders on the
affected knee joint. A KT-2000 arthrometer was used to measure anterior displacement of
the tibia against the femur. Surface electromyography was used to detect the muscle
activation of the vastus medialis oblique, vastus lateralis, biceps femoris, and
semitendinosus before and after neuromuscular training. [Results] There was significant
relaxation in tibial anterior displacement of the affected and sound sides in the supine
position before neuromuscular training. Furthermore, the difference in the tibial anterior
displacement of the affected knee joints in the standing position was reduced after
neuromuscular training. Moreover, the variation of the muscle activation evoked higher
muscle activation of the vastus medialis oblique, vastus lateralis, biceps femoris, and
semitendinosus. [Conclusion] Neuromuscular training may improve functional joint stability
in patients with orthopedic musculoskeletal injuries in the postoperative period.
