PICO

Patient/Population

Patients over 18 years of age diagnosed with myofascial chronic pain syndrome according to Simon’s Diagnostic Criteria (n=61)

Intervention

  • LLLT

Comparison

  • RSWT

Outcomes

  • Pain

  • Functional impairment

  • Quality of life

  • Need for painkiller medication

Translatability:   (3/3) Easy                                    

Comments: The results showed that both therapies were effective in improving pain tolerance, neck functionality, and overall quality of life for the patients. However, it was found that shockwave therapy had a higher level of clinical effectiveness compared to laser therapy.

Limitations: High SD for outcome measures and age of the participants. Some uncertainties about ESWT and LLLT application parameters. Only 15 weeks, follow-up no medium-term and long-term effects demonstrated. The inclusion criteria of 8 weeks of symptoms may be considered short.
