Many needling therapy techniques for MTrP inactivation exist. Based on prior human and animal studies, multiple insertions can almost completely eliminate the MTrP pain forthwith. It is an attempt to stimulate many sensitive loci (nociceptors) in the MTrP region to induce sharp pain, referred pain or local twitch response. Suggested mechanisms of needling analgesia include effects related to immune, hormonal or nervous system. Compared to slow-acting biochemical effects involving immune or hormonal system, neurological effects can act faster to provide immediate and complete pain relief. Most likely mechanism of multiple needle insertion therapy for MTrP inactivation is to encounter sensitive nociceptors with the high-pressure stimulation of a sharp needle tip to activate a descending pain inhibitory system...

A randomized-controlled animal study.Subjects.Twelve adult New Zealand rabbits.Methods.For each rabbit, a MTrS (equivalent to a myofascial trigger point in humans) in one side of the biceps femoris muscle was randomly selected for MIRE treatment (experimental side), while another MTrS in the other side (control side) received a sham treatment. The intervention consisted of a daily 40 minutes treatment, three times per week for 2 weeks. The prevalence of endplate noise (EPN) loci in the MTrS was assessed before, immediately after, and one week after the completion of the 2-week treatment.Results.MIRE could suppress the prevalence of EPN in the MTrS. The degree of reduction in EPN prevalence in the MTrS between the experimental side and the control side was significantly different immediately aft...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADAS... more Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) syndrome is a hereditary disease resulting from NOTCH3 gene mutation. The clinical presentations include migraine, recurrent stroke, and cognitive impairment. The severity of cognitive impairment varies in different stages, and early recognition poses a challenge. A 47-year-old lady presented with chronic migraine and sudden onset of hemiparesis. Magnetic resonance imaging revealed compatible findings of CADASIL, which was confirmed by mutation analysis of NOTCH3 gene. Early cognitive impairment was detected by her score of 3 in Ascertain Dementia 8 (AD8) questionnaire and confirmed by detailed neuropsychological assessments. After 21 months of follow-up, deterioration in her cognition and ability to perform instrumental activities of daily living were significant with a follow-up AD8 score of 7. Ascertain Dementia 8 questionnaire is an easy and valid screening tool for early cognitive impairment in patients with CADASIL syndrome.

Conclusion. Our study suggests that MIRE may be a useful therapeutic option for the management of the myofascial trigger point in humans.
