| Summary: | 碩士 === 中國醫藥學院 === 中國醫學研究所 === 86 === The myofascial pain syndrome is a neuromuscular dysfunction due to trigger point in skeletal muscle, it can happen in any skeletal muscle. It is usually caused by trauma, inflammatory disease, or overwork fatigue etc. It can also be caused by the cumulative effect of long standing repetitive minor trauma or long standing muscle tension due to poor posture, occupational disease, emotional stress. Cervical myofascial pain syndrome is the specific site affected by neck muscles, resulting pain and stiffness on the neck with having disturbance in autonomic conditional phenomena, such as headache, dizziness, nausea, vomiting and insomnia, which have affected patients' daily activities and lives. The purpose of this research is to evaluate quantitatively and to study objectively the immediate effect of treatment on trigger point with several physical medicine modalities in order to understand more the clinical application of electroacupuncture (EA) stimulation and transcutaneous electrical nerve stimulation(TENS) on myofascial pain. Sixty-six patients with cervical myofascial pain are randomly divided into three physical medicine modalities' combinations.
The first group: cervical hot pack plus stretch exercise. The second group: cervical hot pack plus 100 Hz EA at bilateral Fengchi and Jianjing acupoint as well as stretch exercise. The third group: cervical hot pack plus 100Hz TENS and stretch exercise. The improved degree of visual analogue scale(VAS), pain threshold and pain tolerance valves at trigger points are recorded for the comparison of the immediate effect between the three therapeutic groups. Paired t-test and one way ANOVA are used for statistical analysis of data.
The results showed that: (1) The three groups got significant improvement in pain reduction by evaluation of VAS after treatment, but the immediate therapeutic effect had no significant difference between the three groups. (2) There was statistical, significant improvement of pain threshold in EA group after treatment ,but not in control group and TENS group. (3) There was not statistical, significant improvement of pain tolerance in the three group after treatment. It would appear that EA could effectively promote pain threshold of trigger point as treatment for myofascial pain syndrome.
