This study investigated how age, sex, height, body weight, self-efficacy beliefs, pain, and subjective disability predict the performance of low back pain patients on an isokinetic trunk muscle test.
One hundred and five patients participated in the study. Dependent variables were isokinetic flexion and extension strength measured as total work done at speeds 50, 100, and 150 degrees/second.
The anthropometric measures were poor predictors, height being the only significant one. Body weight and age were of no relevance for the performance. Subjective pain and disability had negative effects on the performance of men, but not of women. Self-efficacy beliefs, i.e., the patient's belief in his or her capability to endure physical activities, was the most powerful predictor.
For the purpose of validation, standardization, and interpretation of isokinetic performance in low back pain patients, these factors should be taken into account.
本研究调查了年龄、性别、身高、体重、自我效能信念、疼痛和主观残疾如何预测腰痛患者在等速躯干肌肉测试中的表现。
105名患者参与了该研究。因变量是等速屈伸力量，以50、100和150度/秒速度下完成的总功来衡量。
人体测量指标是较差的预测因素，身高是唯一显著的指标。体重和年龄与表现无关。主观疼痛和残疾对男性的表现有负面影响，但对女性没有。自我效能信念，即患者对自己忍受体力活动能力的信念，是最有力的预测因素。
为了验证、标准化和解释腰痛患者的等速表现，应考虑这些因素。
