在骨科领域，关节病（OA）和类风湿性关节炎（RA）通常被视为典型的疼痛疾病。下肢肌肉强化训练常作为膝关节疾病患者的一般康复治疗；关节本体感觉功能（运动和关节角度的感觉）对改善ADL也很重要。在本研究中，我们将重点放在膝关节上，以揭示膝关节本体感觉（膝关节的阈值和位置感觉）与膝关节周围肌肉力量（膝关节的伸展和屈曲扭矩）之间的关系。结合临床实际病例，我们独立制作了“肌肉退化与关节本体感觉下降关系模型”，考虑肌肉退化对关节本体感觉的影响。对10例健康女性（平均年龄19.5±0.5岁）的20个肢体的膝关节阈值和体位感觉进行了测量。同时测量股四头肌和股二头肌的肌力。我们用自己设计制造的机器测量膝关节阈值和位置感觉。膝关节本体感觉测量阈值与位置感觉之间的相关系数r=0.89 (p<0.01)，膝关节屈曲扭矩与伸屈扭矩之间的相关系数r=0.81 (p<0.01)，显示出较强的相关性。膝关节本体感觉（阈值和位置感觉）与膝关节肌力（屈伸扭矩）呈负相关，表明膝关节肌力可能与膝关节本体感觉有关。
In the orthopedics field, gonarthrosis (OA) and rheumatoid arthritis (RA) are often seen as typical pain disorders. Exercises for muscle reinforcement of the lower limbs are often performed as general rehabilitation for patients with knee joint disorder; joint proprioception function (sensation of movements and joint angle) is also important for improving ADL. In this study, we focused on the knee joint in order to reveal the relationship between knee joint proprioception (threshold value and position sensation of the knee joint) and muscle strength around the knee joint (extension and flexion torque of the knee). Considering the actual cases in clinical context, we independently made “a relationship model of muscle deterioration and joint proprioception decline” for considering the effect of muscle deterioration on joint proprioception. The knee joint threshold value and position sensation of 20 limbs of 10 healthy women (average age 19.5 ± 0.5) were measured. Also the muscle force of quadriceps femoris and biceps femoris were measured. We used a machine which was designed and built by ourselves for measurement of the knee joint threshold value and position sensation. The measurement of knee joint proprioception gave a correlation coefficient, r=0.89 (p<0.01), in the relationship between the threshold value and position sensation, and the knee joint torque gave a correlation coefficient, r=0.81 (p<0.01), in the relationship between the extension and flexion torque, revealing strong respective correlations. Also the relationship between knee joint proprioception (the threshold value and position sensation) and knee joint muscle strength (the extension and flexion torque) showed a general negative correlation revealing the possibility that knee joint muscle strength is associated with the knee joint proprioception.
