Myoelectric Activity of Upper Trapezius Trigger Point

Egypt60 participantsStarted 2020-02-15

Plain-language summary

Myofascial trigger points are a muscular dysfunction at the level of the motor end-plate and the sarcoplasmic reticula that, in turn, cause a local contraction with ischemia -induced hypoxia. Along with the hypoxia, the resulting energy crisis leads to a sensation of the surrounding nociceptors . Extracorporeal shock wave therapy (ESWT) is recently considered an effective treatment for myofascial pain syndrome. It's been proved an effective in musculoskeletal disease fasciitis . It is significant since it is a non-invasive and simple treatment, easy to apply at a large surface, and has fewer side effects with low intensity even if it requires relatively high cost, ESWT has been proved to be more effective than conventional ultrasound on MTrPs in the upper trapezius muscle and showed that ESWT is more effective . It has been found that three sessions of ESWT significantly improved pain levels, neck disabilities, and the quality of life by reducing the number of MTrPs . ESWT could reduce the pain of myofascial pain syndrome by pain signal alteration, promoting angiogenesis and increasing perfusion in ischemic tissues induced by sensitization of nociceptors and muscle ischemia. Ultrasound with deep heat is used in treatment of myofascial trigger point due to the properties of achieving vasodilation, accelerating the metabolism, increasing viscoelasticity and reducing pain and muscle spasm High power pain threshold ultrasound found to be effective in many literatures in treatment of myofascial trigger point . Study was performed comparing effect of high power pain threshold ultrasound with conventional ultrasound proved that high power pain threshold is more effective in treating upper trapezius myofascial It was found in the treatment of MPS, HPPT US therapy could be considered as a reliable and more effective and has positive effect method than low-dose and conventional US therapies This study will be presented as a part of ongoing study. The ongoing study investigates the effect of different intensities of ultrasound on upper trapezius trigger points. The current study will investigate the myoelectric activities of trigger points after application of high power pain threshold ultrasound

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
