Efetividade da ventosaterapia na incapacidade cervical de indivíduos com cervicalgia crônica

Abstract

Introduction: Chronic neck pain is a musculoskeletal disorder, highly prevalent in the world population and has an association of disorders that includes headache and radiant pain in the arm and neck, symptoms in these cases of presence of active myofascial trigger point (PGM), without head trauma fibers descendants. This dysfunction causes a high disability in cervical inflammation, has a marked socioeconomic impact and knows that there are a variety of therapeutic techniques for the removal of PGMs and those with wind therapy, widely used in clinical practice, manifested as a relevant therapeutic practice for such dysfunction. Objective: to analyze the effect of wind therapy on cervical disability at myofascial trigger points in the trapezius muscle descending fibers in patients with chronic neck pain. Objective: To evaluate the effect of ventosatherapia on cervical disability at myofascial trigger points in the trapezius muscle descending fibers in patients with chronic neck pain. Methodology: It is a quasi experimental study, in which the individual had active and bilateral PGM in the trapezius muscle descending fibers and cervical functional disability ≥ 5 points, assessed using the Cervical Disability Index (NDI). The Numerical Pain Scale (END) was used; the Pressure Pain Threshold (LDP) assessed with an INSTRUTERM® PTR-300 algometer; the Cutaneous Temperature (TC), measured with a FLIR® T650 thermal camera. The suction cup consists of an acrylic cup with a diameter of 4 cm and a volume of 260 ml and a manual suction pump that generates negative pressure inside the cup. It was applied exactly over the PGM, bilaterally and simultaneously, for 10 minutes, for 5 sessions. Follow-up was done 24 hours and 1 week after the last intervention. The data were presented as mean and standard deviation in the pre and post treatment, being compared using the paired sample t test for intra-group comparison. Results: Thirteen individuals were evaluated, 84.6% female (11 patients). The score in the END in the pre, post 24h and 1 week post was 6.15 (± 1.68), 1.85 (± 2.15), 3.15 (± 2.94) points, respectively. The NDI score in the pre-intervention was 16.85 (± 6.20), in the 24h post it was 7.15 (± 5.21) and in the post 1 week a score of 8.69 (± 6.09) was noted. LDP D recorded 1.28 (± 0.56), 1.95 (± 0.58) and 1.61 (± 0.59), in the pre intervention moments, 24 hours after the intervention and with a follow-up of 1 week, respectively. The LDP E was 1.22 (± 0.61), 1.86 (± 0.68) and 1.58 (± 0.66) in the pre intervention moment, 24 hours after the intervention and with a follow-up of 1 week, respectively. The initial CT in PGM D was 32.43 (± 0.98) ºC and in PGM E it was 32.46 (± 0.62) ºC. At the 24h post-intervention moment, 32.57 (± 1.00) ºC in PGM D and 32.69 (± 0.96) ºC in PGM E, and in the 1-week follow-up, the CT recorded 32.83 (± 0.63) ºC and 32.69 (± 0.74) ºC in PGM D and PGM E, respectively. Conclusion: Wind therapy caused an increase in the pressure pain threshold, thus reducing the pain intensity, in addition to a slight and insignificant increase in skin temperature, resulting in a consequent improvement in cervical function, by reducing the score on the Cervical Disability Index in a patient with chronic neck pain.
