Summary

This quasi-experimental study was designed to evaluate the effects of an eight-week foot core training program on foot pain, foot function, and pressure pain sensitivity in individuals with fibromyalgia. Participants were recruited among individuals diagnosed with fibromyalgia according to the American College of Rheumatology (ACR) and the American Pain Society-American Academy of Pain Medicine (AAPT) criteria. The intervention consisted of a structured foot core training program focused on strengthening the intrinsic foot musculature. Assessments were conducted before and after the intervention period. Outcome measures included foot pain and foot function assessed using the Foot Health Status Questionnaire (FHSQ), as well as pressure pain thresholds measured using mechanical algometry at six predefined rearfoot anatomical points.

Detailed description

This quasi-experimental study was designed to evaluate the effects of an eight-week foot core training program on foot pain, foot function, and pressure pain sensitivity in individuals with fibromyalgia. Participants were recruited from individuals diagnosed with fibromyalgia in accordance with the criteria established by the American College of Rheumatology (ACR) and the American Pain Society-American Academy of Pain Medicine (AAPT). The intervention consisted of a structured foot core training program aimed at strengthening the intrinsic musculature of the foot and was implemented over an eight-week period. The program was designed to be delivered in a systematic and progressive manner. Assessments were performed prior to the initiation of the intervention and at the end of the eight-week training period. Outcome measures included foot pain and foot function, assessed using the Foot Health Status Questionnaire (FHSQ). Pressure pain sensitivity was evaluated using mechanical algometry, with pressure pain thresholds recorded at six predefined anatomical points of the rearfoot. All measurements were conducted following standardized procedures and by trained personnel. The data collected were intended to examine changes in foot-related outcomes and pressure pain sensitivity following completion of the intervention.

Conditions

• Fibromyalgia
• Foot Core

Interventions

Type	Name	Description
OTHER	Foot Core	Eight-week supervised foot core training (2×/week, 45 min) including mobility, intrinsic foot muscle strengthening, and progressive balance tasks. Exercises progressed from basic activation to standing and single-leg control. Load was individualized to prevent symptom exacerbation and ensure safe participation.
