摘要

Objective. To analyse the effect of the manual ischemic compression (IC) on the upper limb motor performance (MP) in patients with LTrPs. Materials and Methods. A quasiexperimental study was performed in twenty subjects allocated to either patients group with LTrPs (PG, n=10) or healthy group with no symptoms (HG, n=10). Subjective pain and linear MP (movement time and Fitts’ Law) were assessed before and after a linear tapping task. Data were analysed with mixed factorial ANOVA for intergroup linear motor performance differences and dependent t-student test for intragroup pain differences. Results. PG had a linear MP lower than the HG before treatment (p 0.05). After IC, the PG showed a significant decrease of pain (4.07 ± 1.91 p 0.001). Furthermore, the movement time (15.70 ± 2.05 p 0.001) and the Fitts’ Law coefficient (0.80 ± 0.53 p 0.001) were significantly reduced. However, one IC session did not allow the PG to get the same MP than the HG (p 0.05). Conclusion. The results suggest the IC effectiveness on pain and MP impairment in subjects with LTrPs. However, the MP of these patients is only partially improved after the IC application.
