DIFFERENCE IN PERCEIVED PAIN INTENSITY DEPENDING ON THE ORDER OF SUBMAXIMAL ISOMETRIC CONTRACTIONS PERFORMED AT DIFFERENT INTENSITIES
Abstract
Methods: Twenty-nine volunteers participated (mean age=22.10±1.60 years) to the study. Hamstring flexibility was measured in the supine position. Maximal voluntary contraction (MVC) was measured during hip extension. Submaximal contractions were performed at two different target intensities: 25% and 75% of MVC. Visual Analogue Scale (VAS) was used to measure the pain after submaximal contractions. Group A (n=15) performed submaximal contraction in 25% to 75% of MVC in the 1st period and 75% to 25% of MVC in the 2nd period. In Group B (n=14), the submaximal contraction was performed in each period in the opposite order of Group A.
Results: There was a significant decrease in pain in Group B during the 2nd period (p<0.05). The VAS at 75% of the MVC showed a significant decrease at 25% of the MVC (p=0.011). Correlations were observed between flexibility and 1st-period VAS score (p=0.048) and 2nd-period VAS score (p=0.036) and between the VAS scores in the 1st and 2nd periods (p<0.001).
Conclusion: Pain intensity could be perceived differently depending on the order of sequential application, even when the intensities are identical, and might be more clinically useful in the analysis of intra-individual comparisons.
