Hemophilia is an inherited bleeding disorder that is commonly associated with chronic joint pain, reduced physical function, and decreased quality of life. Pain science education combined with exercise therapy has shown beneficial effects in people with chronic musculoskeletal pain; however, its effectiveness in people with hemophilia remains largely unknown. Telerehabilitation may improve access to rehabilitation by reducing geographical and transportation barriers, but its effectiveness compared with face-to-face delivery has not been established in this population. This randomized controlled non-inferiority trial will compare a 6-week multimodal telerehabilitation program consisting of pain science education and therapeutic exercise with an equivalent face-to-face program in adults with hemophilia and chronic pain. Participants will be randomly assigned to one of the two interventions. Clinical outcomes will be assessed before and after the intervention by an assessor blinded to group allocation. The study aims to determine whether telerehabilitation provides clinical outcomes that are not inferior to those achieved with conventional face-to-face rehabilitation.
Chronic pain affects nearly half of adults with hemophilia and is associated with impaired physical function, kinesiophobia, reduced self-efficacy, and poorer quality of life. Recurrent joint bleeding and hemophilic arthropathy contribute to persistent pain and disability, highlighting the need for accessible and effective rehabilitation strategies. Pain science education (PSE) is an educational intervention designed to improve understanding of the biological and psychosocial mechanisms underlying persistent pain, reduce pain-related threat, and promote adaptive health behaviors. When combined with exercise therapy, PSE has demonstrated beneficial effects in individuals with chronic musculoskeletal disorders. However, evidence supporting its use in people with hemophilia is scarce. Telerehabilitation has emerged as a promising strategy to improve access to rehabilitation services by reducing travel burden and geographical barriers while maintaining treatment adherence. Although previous studies suggest that telerehabilitation may provide outcomes comparable to conventional rehabilitation in several musculoskeletal conditions, no randomized controlled trial has compared multimodal pain science education plus exercise delivered by telerehabilitation with an equivalent face-to-face program in adults with hemophilia and chronic pain. This study is a single-center, randomized, assessor-blinded, parallel-group non-inferiority trial. Participants will be randomly allocated (1:1) to receive either a 6-week telerehabilitation program or an equivalent face-to-face program. Both groups will receive the same educational content and exercise protocol, differing only in the mode of delivery. The primary objective is to determine whether multimodal telerehabilitation is non-inferior to face-to-face rehabilitation in reducing pain intensity and improving pain sensitivity. Secondary objectives include evaluating changes in kinesiophobia, self-efficacy, joint health, functional performance, and patient-perceived improvement. The results of this trial will provide evidence regarding the effectiveness of multimodal telerehabilitation for adults with hemophilia and may support the implementation of accessible rehabilitation models in clinical practice.

A standardized pain neuroscience education program delivered once weekly for 6 weeks. Educational sessions focus on the neurobiology and neurophysiology of pain, pain modulation, central sensitization, the influence of cognitive and emotional factors on pain, and strategies to promote adaptive self-management and behavior change. The educational content is identical in both study arms and differs only in the mode of delivery (telerehabilitation or face-to-face).
A standardized supervised exercise program delivered once weekly for 6 weeks. Each session includes a warm-up, joint mobility exercises, stretching, and progressive strengthening exercises for major muscle groups. Exercise intensity is progressively increased according to participants' perceived exertion using the Borg CR10 scale. The exercise protocol is identical in both study arms and differs only in the mode of delivery.

RECRUITINGPain Intensity
Pain intensity will be assessed using the 100-mm Visual Analog Scale (VAS) for Pain, ranging from 0 mm (no pain) to 100 mm (worst imaginable pain). Higher scores indicate greater pain intensity.
Time frame: Baseline and immediately after the 6-week intervention.
Kinesiophobia
Kinesiophobia will be assessed using the 11-item Tampa Scale for Kinesiophobia (TSK-11). Total scores range from 11 to 44, with higher scores indicating greater fear of movement (kinesiophobia).
Time frame: Baseline and immediately after the 6-week intervention.
Pain Self-Efficacy
Pain self-efficacy will be assessed using the 2-item Pain Self-Efficacy Questionnaire (PSEQ-2). Total scores range from 0 to 12, with higher scores indicating greater confidence in performing activities despite pain.
Time frame: Baseline and immediately after the 6-week intervention.
Functional Performance
Functional performance will be assessed using the 30-Second Sit-to-Stand Test (30s STS). The outcome is the number of completed sit-to-stand repetitions performed in 30 seconds. Higher values indicate better functional performance.
Time frame: Baseline and immediately after the 6-week intervention
Pressure Pain Threshold
Pressure pain threshold will be assessed using a digital pressure algometer. The average of three measurements will be recorded at each assessment. Higher values indicate lower pain sensitivity.
Time frame: Baseline and immediately after the 6-week intervention.
