躯干力量测量27名健康男性和30名健康女性，并在25名男性和15名女性患者腰痛和/或坐骨神经痛。最大的自愿等长力量进行了测量，在尝试屈曲，伸展和侧弯从直立的立场。男性和女性患者的躯干绝对力量约为相应健康受试者的60%。个体内躯干强度比被用来解释结果。使用这些比率往往可以避免由于患者的普遍虚弱以及患者或健康受试者缺乏动力而产生的解释问题。这些比率表明，患者尝试的伸展强度明显低于他们在其他类型的运动测试中的强度。坐骨神经痛患者尝试伸展的强度比特别低。
Trunk strengths were measured in 27 healthy males and 30 healthy females, and in 25 male and 15 female patients with low back pain and/or sciatica. Maximum voluntary isometric strengths were measured during attempted flexion, extension and lateral bending from an upright standing position. Both male and female patients had approximately 60% of the absolute trunk strengths of the corresponding healthy subjects. Intraindividual trunk strength ratios were used to interpret the results. Use of these ratios tends to avoid interpretational problems created by the general weakness of the patients and any lack of motivation of either patients or healthy subjects. The ratios showed that the patients attempted extension strengths that were significantly less than their strengths in the other types of movements tested. Strength ratios for attempted extension were particularly low for patients with sciatica.
