Brief Summary

Fibromyalgia (FM) is a primary chronic pain condition with an estimated prevalence of 3.3% in Chile. It is characterized by widespread musculoskeletal pain, fatigue, and impaired physical function. Although exercise therapy is considered the first-line intervention, barriers to access and poor adherence limit its effectiveness within the public healthcare system. This study evaluates the effectiveness of an Artificial Intelligence (AI)- and Computer Vision (CV)-assisted telerehabilitation platform called Rehbody. The aim is to determine whether real-time technology-driven feedback can overcome the limitations of traditional face-to-face rehabilitation models by improving disease impact and functional capacity in Chilean patients with fibromyalgia.

Outcome Measures

Primary Outcomes (2)

  • Fibromyalgia Impact Questionnaire-Revised (FIQ-R)

    The Fibromyalgia Impact Questionnaire-Revised (FIQ-R) is a 21-item self-reported instrument that assesses physical function, overall impact, and symptom severity in individuals with fibromyalgia. The Chilean validated version demonstrates excellent internal consistency (Cronbach's α = 0.91), good test-retest reliability (ICC = 0.90), and adequate convergent validity through significant correlations with pain intensity, pain interference, symptom severity, and health-related quality of life (Escobar, 2018). Total scores range from 0 to 100, with higher scores indicating greater disease impact. The questionnaire requires approximately 1.3 minutes to complete (Carrasco-Vega et al., 2023). A 14% change in the total FIQ-R score was considered the Minimal Detectable Change (MDC) (Bennett, Friend, et al., 2009). Assessments will be conducted at baseline (Week 0), post-intervention (Week 13), and follow-up (Week 25).

    6 months

  • 30-Second Sit-to-Stand Test (30s-STS) Performance

    The 30-Second Sit-to-Stand Test (30s-STS) assesses lower-limb strength through a physical performance measure. It has demonstrated good to excellent test-retest reliability (ICC: 0.85-0.91), adequate known-groups validity for distinguishing individuals with and without fibromyalgia, and a minimal detectable change of ≥3 repetitions (Socorro-Cumplido et al., 2024). The test is associated with handgrip strength, muscle mass, balance, functional capacity, overall physical performance, and mobility- and quality of life-related outcomes (Kakavas et al., 2020; Khuna et al., 2024). Participants are instructed to perform as many sit-to-stand repetitions as possible within 30 seconds without using their arms, while the assessor records the total number of repetitions. The 30s-STS has been validated for remote administration in telehealth settings and for use in the Chilean population. Assessments will be conducted at baseline (Week 0), post-intervention (Week 13), and follow-up (Week 25).
