Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Myofascial pain syndrome is one of the common causes of musculoskeletal pain seen in clinical practice and is characterized by the presence of trigger points associated with sensitive areas such as taut bands of skeletal muscle. It may also be accompanied by referred pain, which is pain in other parts of the body. Although the pathophysiology and etiology of myofascial pain syndrome and trigger points are still unknown, there are reports that myofascial pain is a complex form of neuromuscular dysfunction caused by motor and sensory abnormalities involving both the peripheral nervous system and the central nervous system. Recently, it has been considered as a method of treatment for myofascial pain syndrome. In addition, although pain reduction and functional improvement of focused ESWT in patients with myofascial pain syndrome have been reported, related studies are lacking on the effect of focused ESWT according to the frequency difference. The purpose of the study is to examine the efficacy and safety of focused type ESWT frequency in patients with myofascial pain syndrome.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
20

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Those diagnosed with myofascial pain syndrome according to Simon's criteria
  2. Pain is 4 points or more on the Numerical Rating Scale (NRS)

Exclusion Criteria:

  1. Pain is due to trauma, fibromyalgia and neurological disorders including neuromyopathy, myelopathy, and stroke
  2. If you have received injection treatment for trigger points within the last 2 months or have had surgery on the painful area within 1 year
  3. If there is a high risk of bleeding due to severe coagulopathy, etc. or if you have recently had severe bleeding (except taking antiplatelet)
  4. If you have a tumor, infection, kidney failure, severe liver disease, epilepsy, skin disease, or mental retardation

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline NRS (numerical rating scale) at each time frame
Time Frame: baseline, immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment
Pain intensity (0-10, ordinal scale)
baseline, immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of treatment-related adverse events as assessed by CTCAE v4.0 at each time frame
Time Frame: immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment
Common Terminology Criteria for Adverse Events
immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment
