Abstract

The elbow reflex, a principal reflex in the upper extremity, plays an important role in the diagnosis of cervical spine syndromes. In this study, the muscle activations of brachial biceps and triceps, and the kinematics of upper extremities were predicted using an activation model for the stretch reflex. The muscle activations that equated the simulation results estimated by the analysis model with the experimental results were obtained first, and the activations obtained from the simulations were compared with the electromyography signals obtained from the experiments, for model validation. The root mean squares error of the joint angles (obtained from experiments and simulation using the suggested model) was 0.056, a value that is half of that obtained using the previous model. This demonstrates that the suggested model corresponded well with the actual reflex.

삼두박근 반사는 인체 상지에서 발생하는 대표적인 신장반사이며 경추의 이상 등을 판단하는데 중요한 역할을 수행한다. 본 연구에서는 이를 생체역학적으로 해석하기 위하여 새롭게 정의된 신장반사 해석 모델을 이용하여 해석적으로 상완 이두박근과 삼두박근의 근활성도 및 상완의 운동 정보를 예측하였다. 해석을 통해 예측된 운동 정보와 실험 결과가 같도록 하는 근활성도를 구하고, 이를 근전도 실험 결과와 비교하여 해석 모델과 방법의 타당성을 검증하였다. 제안된 모델과 실험을 통해 얻은 관절의 각도들의 최소자승오차는 0.056 으로 기존의 모델을 사용하여 얻은 오차의 절반 수준이다. 이것은 제안된 모델이 실제 현상과 잘 부합한다는 것을 나타낸다.
