Protocol in Musician's Focal Dystonia (MISA) (MISA)

3 de novembro de 2026 atualizado por: Fondazione Don Carlo Gnocchi ETS

Effectiveness of the MISA (Mirror Integrated Sensorimotor Approach) Rehabilitation Protocol for Musicians With Focal Dystonia: A Retrospective Observational Study

Musician's Focal Dystonia (MFD) is a task-specific movement disorder that impairs fine motor control during musical performance and may severely affect professional and amateur musicians. The Modified Integrated Sensorimotor Approach (MISA) is a standardized home-based rehabilitation program that combines mirror therapy, sensory reorganization exercises, graded motor training, and motor awareness strategies to promote sensorimotor retraining.

This retrospective observational study aims to evaluate the association between participation in the MISA rehabilitation program and changes in musical performance among musicians with focal hand dystonia. Musical performance is assessed using the Technical Ability and Performing Scale (TAPS), a patient-reported outcome measure specifically developed for musicians with focal dystonia. Secondary objectives include the investigation of clinical and individual factors potentially associated with treatment response.

The study consists of a review of clinical records of patients who completed the MISA program as part of routine clinical care at the Sol Diesis Outpatient Clinic, IRCCS Fondazione Don Carlo Gnocchi, Milan, Italy.

Descrição detalhada

Musician's Focal Dystonia (MFD) is a task-specific movement disorder characterized by loss of fine motor control, involuntary muscle contractions, and abnormal movement patterns that emerge during musical performance. The condition is thought to result from maladaptive neuroplasticity, impaired sensorimotor integration, and abnormalities in cortical inhibitory mechanisms. These alterations interfere with highly trained motor skills and may profoundly affect professional and amateur musicians.

Although pharmacological treatments, including botulinum toxin injections and oral medications, may provide symptomatic benefit, rehabilitation interventions have become an increasingly important component of MFD management. Previous studies have suggested that sensorimotor retraining approaches, including mirror therapy, sensory reorganization, graded motor training, and motor control exercises, may improve musical performance and reduce dystonic symptoms.

The Modified Integrated Sensorimotor Approach (MISA) is a structured home-based rehabilitation protocol developed at the Sol Diesis Outpatient Clinic of IRCCS Fondazione Don Carlo Gnocchi. The protocol integrates mirror therapy, sensory reorganization exercises, graded motor training, and motor awareness strategies within a progressive framework of increasing task complexity. The intervention aims to promote adaptive sensorimotor reorganization, improve movement selectivity, reduce maladaptive co-contraction patterns, and facilitate transfer of acquired motor skills to musical performance.

This retrospective observational study involves the review of medical records of adult musicians with instrument-specific focal dystonia who underwent the MISA rehabilitation program as part of routine clinical care between July 2017 and May 2026. Data collected include demographic and professional characteristics, clinical features of dystonia, treatment characteristics, and musical performance outcomes.

Musical performance was assessed using the Technical Ability and Performing Scale (TAPS), a patient-reported outcome measure specifically developed for musicians with focal dystonia. Assessments performed before treatment initiation (T0) and at completion of the rehabilitation program (T1) were used to evaluate treatment-related changes.

The primary objective of the study is to explore the association between participation in the MISA rehabilitation program and changes in musical performance measured by TAPS scores. Secondary objectives include the investigation of associations between treatment-related changes and individual or clinical characteristics of participants, including age, sex, instrument played, disease duration, dystonia pattern, and affected body segments.

The study is conducted in accordance with the Declaration of Helsinki and was approved by the Ethics Committee CET Lombardia 4 (Approval No. CET 90-26).

Musicians With Focal Hand Dystonia Treated With MISA

Adult professional and amateur musicians with instrument-specific focal hand dystonia who completed the Modified Integrated Sensorimotor Approach (MISA) rehabilitation program as part of routine clinical care. Participants were evaluated at baseline and after completion of the rehabilitation program using the Technical Ability and Performing Scale (TAPS).

The Modified Integrated Sensorimotor Approach (MISA) is a standardized home-based rehabilitation program for musicians with focal hand dystonia. The intervention combines mirror therapy, sensory reorganization exercises, graded motor training, motor awareness strategies, and progressive task-oriented practice. The program consists of six modules delivered across approximately 12 weeks, with individualized instruction provided by a physiotherapist and independent home exercises performed four days per week.
