An observational study in Myofascial Pain Syndromes, sponsored by KTO Karatay University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-31.
Sponsored by KTO Karatay University · Observational
This cross-sectional study aims to determine the predictors of treatment expectations in individuals with myofascial pain syndrome (MPS). MPS is one of the most common causes of musculoskeletal pain and is associated with reduced quality of life. Patients' pre-treatment expectations are known to influence clinical outcomes, yet the factors that predict these expectations have not been established. Adults diagnosed with MPS who are scheduled to receive physiotherapy complete measures of treatment expectations, pain intensity and duration, health-related quality of life, and fatigue. Multiple regression analysis is used to examine the extent to which pain intensity, pain duration, quality of life, and fatigue predict treatment expectations.
Design and setting: Cross-sectional, descriptive study conducted at a private physiotherapy clinic in Konya, Turkiye, between April and August 2026.
Participants: Adults (18 years and older) with a diagnosis of MPS, a pain intensity of at least 3 on a visual analog scale, and scheduled to receive at least two weeks of physiotherapy. Individuals with a psychiatric diagnosis, a chronic systemic disease, or any barrier preventing communication are excluded.
Sample size: Based on an a priori power analysis (G*Power; effect size 0.15, power 0.80, alpha 0.05), a minimum of 85 participants is required.
Measures: A personal information form; the Treatment Expectation Questionnaire (TEX-Q), Turkish version, as the dependent variable; pain intensity and duration via a visual analog scale; health-related quality of life via the Short Form-36 (SF-36); and fatigue via the Brief Fatigue Inventory (BFI).
Analysis: Descriptive statistics, the Shapiro-Wilk test for normality, and multiple linear regression models (with 95% confidence intervals) to examine the associations between treatment expectations and pain intensity, pain duration, quality of life, and fatigue. Statistical significance is set at p\<0.05.

Adults (18 years and older) diagnosed with myofascial pain syndrome who present to a private physiotherapy clinic in Konya, Turkiye and are scheduled to receive at least two weeks of physiotherapy.
Exclusion Criteria:
Adults with a diagnosis of myofascial pain syndrome presenting to a private physiotherapy clinic and scheduled to receive at least two weeks of physiotherapy. Treatment expectations and candidate predictors are assessed once at enrollment.
Treatment expectations
Measured with the Treatment Expectation Questionnaire (TEX-Q), Turkish version. The total score of the first 15 items ranges from 0 to 150, with higher scores indicating greater treatment expectations.
Time frame: At enrollment, before the physiotherapy program (single cross-sectional assessment)
Pain intensity
Assessed with a 10 cm Visual Analog Scale (VAS) for rest, activity, and night pain; 0 = no pain, 10 = unbearable pain.
Time frame: At enrollment (single cross-sectional assessment)
Pain duration
Self-reported duration of pain complaints, recorded in weeks.
Time frame: At enrollment (single cross-sectional assessment)
Health-related quality of life
Assessed with the Short Form-36 (SF-36). Subscale scores range from 0 to 100, with higher scores indicating better health status.
Time frame: At enrollment (single cross-sectional assessment)
Fatigue
Assessed with the Brief Fatigue Inventory (BFI); higher scores indicate greater fatigue.
Time frame: At enrollment (single cross-sectional assessment)
