| ObjectiveThis research adopted the method of bloodletting and cupping therapy, comparing with lidocaine blocking therapy, to observe the clinical effect, mechanism and safety of bloodletting and cupping therapy for myofascial pain syndrome (MPS) in purpose to discover a safety, effective and simple treatment.MethodsThis study collected a total of 66 MPS patients. They were randomly divided into bloodletting and cupping therapy group (treatment group) and lidocaine blocking therapy group (control group),33 cases in each group. In the treatment group, patients were accepted the treatment of pricking method on myofascial trigger points (MTrPs) by the three edged needle and cupping on the bleeding part (the cups retaining time was 10min). In the control group, patients were injected with 0.5% lidocaine in MTrPs. Both of the groups were treated 1 time every three days,5 times as a course of treatment. Before the course and after the third and the fifth treatment, all the patients were evaluating by the McGill scale and pressure threshold including pain perception threshold (PPDT) and pain tolerance threshold (PPTO) to observe the clinical effect. Also, adverse reaction was included in the observation.ResultsTotally,60 patients were completed in this study, each group had 30 patients, the data statistics implied:Before the treatment, there were no significant differences on basic information including age and course of disease, also, the baseline data including the McGill scale and pressure threshold were included between the two groups.On the score of the McGill scale, the treatment group had a sig significantly decrease (P<0.01) at the end of 3rd treatment (16.53±4.26) and at the end of the 5th treatment (9.33±2.88) compared with the beginning (25.03±5.31). There were also significant differences between the 5th treatment and the 3rd treatment’s score. At the same time, the control group had a sig significantly decrease (P<0.01)at the end of the 3rd treatment (15.70 ±3.90) and at the end of the 5th treatment (8.40±2.75) compared with the beginning (24.80±4.91). There were also significant differences between the 5th treatment and the 3rd treatment’s score. The scores of two groups had no significant difference (P>0.05) at the end of 3rd treatment and at the end of the 5th treatment. The difference between before the treatment and after the treatment had no significant difference of two groups. The result implied that both bloodletting therapy and lidocaine blocking therapy can effectively reduce the pain of patients and negative emotions related to pain, and the effect was competitive.On the value of PPDT, the treatment group had a significantly increase (P<0.01) at the end of 3rd treatment (4.08±0.61) and at the end of the 5th treatment (5.67±0.76) compared with the beginning (3.08±0.63). It was also significant difference between the 5th treatment and the 3rd treatment’s score. At the same time, the control group had a sig significantly decrease (P<0.01) at the end of the 3rd treatment (4.00±0.54) and at the end of the 5th treatment (5.52±0.57) compared with the beginning (3.07±0.60). It was also significant difference between the 5"’treatment and the 3rd treatment’s score. The scores of two groups had no significant difference (P>0.05) at the end of 3rd treatment and at the end of the 5th treatment. The difference between before the treatment and after the treatment had no significant difference of two groups. On the value of PPTO, the treatment group had a significantly increase (P<0.01) at the end of 3rd treatment (6.07±0.78) and at the end of the 5th treatment (7.52±0.85) compared with the beginning (4.59±0.92). It was also significant difference between the 5th treatment and the 3rd treatment’s score. At the same time, the control group had a sig significantly decrease (P<0.01) at the end of the 3rd treatment (6.01±0.69) and at the end of the 5th treatment (7.41±0.57) compared with the beginning (4.67±0.65). It was also significant difference between the 5th treatment and the 3rd treatment’s score. The scores of two groups had no significant difference (P>0.05) not only at the end of 3rd treatment but also at the end of the 5th treatment. The scores of two groups had no significant difference (P>0.05) at the end of 3rd treatment and at the end of the 5th treatment. The difference between before the treatment and after the treatment had no significant difference of two groups. The result implied that both bloodletting therapy and lidocaine blocking therapy can effectively reduce the pain of patients objectively.On the adverse reaction,2 patients in control group felt nausea and desire to retch after one of lidocaine blocking therapy and both of them felt well after rest. In treatment group, patients had no obvious adverse reactions.About the shedding cases,2 patients were lost because they couldn’t arrange the right time to the treatment time and 1 patient was removed because of receiving other treatment in other medical institutions in treatment group. There were 3 patients were lost in control group, because one of them couldn’t arrange the right time to the treatment time and two of them afraid of the adverse events. ConelusionThe bloodletting and cupping therapy and lidocaine blocking therapy have equivalent efficacy in MPS. It that shows bloodletting and cupping therapy is an effective, simple and accessible treatment of MPS. |
