Abstract

*To investigate 1. the pressure pain thresholds [PPTs] with respect to low back pain related muscles, and to the M. Triceps brachii as an muscle unrelated to lower back region; 2. to explore the effect of several weekly deep cross-friction massage sessions [roptrotherapy] on PPTs, pain sensitivity and disability in order to verify the model of central sensitization.
Methods: Sixty-five consecutive patients with subacute1 non-specific low back pain [nLBP] were allocated in this clinical trial. The primary outcome measures were the PPTs of levels L1, L3, L5 of the M. Erector spinae and the M. Gluteus maximus. The middle of the left M. Triceps brachii was chosen as a neutral measuring point which is unrelated to nLBP. In addition, pain rating and disability variables were examined. In order to establish reference values, 64 healthy subjects [control group] were examined with respect to similar PPTs.
Results: The mean PPT values of the M. Erector spinae and the M. Gluteus maximus of the LBP group were significantly lower in comparison to the PPT values of the healthy group. An exceptionally high difference [2.8 kg/cm², p <0.001] was found at the L3 M. Erector spinae level. The correlation between having nLBP and PPT was highest at the L3 level of the M. Erector spinae [r = -0.73, p <0.001]. The PPT values of the M. Triceps brachii did not differ significantly between healthy and nLBP subjects. At baseline, the PPTs of the M. Erector spinae levels L1, L3, and L5 increased after three weekly roptrotherapy sessions, yielding a situation in which the patients no longer had back complaints and a PPT similar to that of subjects with no nLBP, while the neutral M. Triceps brachii remained unchanged over the entire time.
