This case report describes the effect of strengthening the quadriceps of an effused osteoarthritic knee joint of a 53-year-old man isometrically in mid-range. The instruments included an isokinetic dynamometer, a knee scoring inventory, and a visual analog scale. The outcome measures of isometric quadriceps torque and work, clinical status, and pain were recorded before and after the exercise intervention. The exercises were carried out three times per week for a 6-week period with the subject seated on an exercise chair. Following training, quadriceps torque increased, clinical status improved, and pain with walking decreased. Subject to further investigation, isometric training of the quadriceps in mid-range could prove useful for improving the function of persons with painful or effused knees who might otherwise experience muscle inhibition by exercising in the more traditional inner ranges of knee extension.
本病例报告描述了对一名53岁男性患有关节积液的骨关节炎膝关节进行等长收缩训练，在膝关节活动范围的中间范围增强股四头肌力量的效果。使用的仪器包括等速测力计、膝关节评分量表和视觉模拟评分量表。在运动干预前后记录等长股四头肌扭矩和功、临床状况及疼痛等结果指标。受试者坐在运动椅上，每周进行3次训练，为期6周。训练后，股四头肌扭矩增加，临床状况改善，行走时疼痛减轻。有待进一步研究的是，在膝关节活动范围中间范围对等长股四头肌进行训练，可能对改善膝关节疼痛或积液患者的功能有用，否则这些患者可能因在更传统的膝关节伸展内侧范围进行锻炼而出现肌肉抑制。
