Myofascial Trigger Points

Abstract Background Current guidelines for the treatment of low back pain (LBP) endorse physical exercise programs and a range of non-pharmacological complementary therapies. Myofascial trigger points (MTrPs) compression therapy is a well-established form of manual therapy, which aims to induce temporary ischemia and over-stimulation of mechanoreceptors over a desired area in order to restore tissue normal functional conditions required for healing response. The purpose of the current study was to evaluate the effect of MTrPs compression therapy as an adjunct to active exercise program in alleviating chronic non-specific low back pain. Methods One-hundred and three patients with chronic non-specific LBP were retrospectively reviewed, 45 of them were treated with MTrPs compression therapy as an adjunct to physical exercise program (MTrPs group) and 58 were treated with exercise program alone (control group). Pain and functional scores were compared before initiating treatment and at 3-month follow-up. Results Pain reduction at 3-month follow-up was 5.6 points (0–10 numerical scale) in the MTrPs group compared to 3.6 points in the control group (p < 0.001). Oswestry Disability Index and SF-12 life quality scores also improved significantly more in the MTrPs group compared to the control group at 3-month follow-up (p < 0.001). Conclusions Myofascial trigger points compression therapy as an adjunct to active exercise program provides superior pain and disability relief to patients with chronic LBP compared to active exercise program alone.

Objectives: To determine how muscle spindles are involved in the pathophysiology of chronic myofascial trigger spots (MTrSs, similar to myofascial trigger points) in a rat injury model according to the characteristics of the Hoffmann reflex (H-reflex) and the anatomical relationship between muscle spindles and MTrSs. Methods: 16 male Sprague-Dawley rats (7 weeks old) were randomly divided into experimental and control groups. A blunt strike injury and eccentric exercise were applied to the gastrocnemius muscle of rats in the experimental group once a week for 8 weeks as a MTrS modelling intervention. Subsequently, the rats were reared normally and rested for 4 weeks. At the end of the 12th week, the rats were examined for the presence of MTrSs defined by the detection of a palpable taut band exhibiting both a local twitch response and spontaneous electrical activity. After modelling, evocation of the H-reflex and morphological examination of muscle spindles and MTrSs were conducted. Results: The threshold (0.35±0.04 mA) of the H-reflex and latency (1.24±0.18 ms) of the M wave recorded at MTrSs were not significantly different to those at non-MTrSs (P>0.05). Compared with non-MTrSs, a lower Mmax (4.28±1.27 mV), higher Hmax (median (IQR) 0.95 (0.80–1.08) mV) and Hmax/Mmax (median (IQR) 0.21 (0.16–0.40)), and shorter H wave latency (4.60±0.89 ms) were recorded at MTrSs (P<0.05). Morphologically, there was a close anatomical relationship between the MTrS cells and the muscle spindles. Discussion: Compared with normal muscles, the H-reflex myoelectrical activity was enhanced and some muscle spindles might have been influenced by active MTrSs. Thus, muscle spindles may play an important role in the pathological mechanism underlying myofascial trigger points.

Abstract Introduction: Current guidelines for the treatment of low back pain (LBP) endorse physical exercise programs and a range of non-pharmacological complementary therapies. Myofascial trigger points (MTP) compression therapy is a well-established form of manual therapy, which aims to induce temporary ischemia and over-stimulation of mechanoreceptors over a desired area in order to restore tissue normal functional conditions required for healing response. The purpose of the current study was to evaluate the effect of MTP compression therapy as an adjunct to active exercise program in alleviating chronic non-specific low back pain.Methods: One-hundred and three patients with chronic non-specific LBP were retrospectively reviewed, 45 of them were treated with MTP compression therapy as an adjunct to physical exercise program and 58 were treated with exercise program alone. Pain and functional scores were compared before initiating treatment and at 3-month follow-up. Results: Pain reduction at 3-month follow-up was 5.6 points (0-10 numerical scale) in the combined treatment group compared to 3.6 points in the exercise program alone group (p<0.01). Oswestry Disability Index improved by 36 and 22 points respectively (p<0.01) and SF-12 life quality score improved by 41 and 29 points respectively (p<0.01). Conclusions: Myofascial trigger points compression therapy as an adjunct to active exercise program provides superior pain and disability relief compared to active exercise program alone for patients with chronic LBP.

Abstract Background: Chronic low back pain is considered to be one of the main causes of absenteeism from work and primary and specialized consultations. The symptoms of non-specific chronic low back pain may be accompanied by the activation of myofascial trigger points in the muscles, together with local and/or referred pain. Electrical dry needling is increasingly used in the treatment of lumbar myofascial pain. Conventional physiotherapy, however, is a popular approach to chronic pathologies, and there is evidence of different modalities of physiotherapy being used in the treatment of chronic low back pain. The aim of this study has been to determine the effectiveness of electrical dry needling versus conventional physiotherapy when applied to active and latent myofascial trigger points in patients with nonspecific chronic low back pain. Methods and Analysis. This is a controlled, randomized, two-arm, double-blind study. A total of 92 patients with chronic low back pain (time to onset ≥ 3 months, Roland Morris Disability Questionnaire score ≥ 4) will be recruited from the University of Almería. Participants will be divided into two study groups (n = 40, respectively) to receive treatment of low back pain with electrical dry needling and conventional physiotherapy (ischaemic compression, analytic stretching and postural education training dossier). A total of 3 sessions will be administered once a week for 3 weeks. Pain intensity, disability, fear of movement, quality of life, quality of sleep, anxiety and depression, pressure pain threshold, abdominal strength, and lumbar mobility will be recorded at 3 weeks (post-immediate) and 2 months after the end of treatment.Ethics and dissemination. Ethics and Research Committee of the University of Almería (UALBIO2020/044). The results of the study will made available to researchers, clinicians and health professionals through publications in international journals and presentations in conferences.Trial registration number: NCT04804228.
