We report here the case of a 63-year-old male, percussionist, with african ethnicity, with musician\u2019s focal hand dystonia who was treated with botulinum toxin, and describe the results at 4-weeks follow up.\nMethods: Clinical examination and video analysis revealed abnormal flexion of the 3rd finger, followed by flexion of the 4th and 5th fingers while playing the congas. Based on these findings, a diagnosis of musician's focal hand dystonia was established. Ten units of botulinum toxin were injected into the muscle fibres of the flexor digitorum superficialis corresponding to the 4th finger using electromyography and ultrasound guidance. Four weeks later, the patient reported a subjective 60% improvement in his performance. He emphasized the effect of botulinum toxin on performance speed and tension over the forearm and hand.\nConclusion: Botulinum toxin is not a definitive treatment for musician\u2019s focal hand dystonia, but it may potentiate other definitive rehabilitation techniques. More research is needed to determine the long-term effects of botulinum toxin on function enhancement in musician\u2019s focal hand dystonia.<\/jats:p>","DOI":"10.2340\/jrm.v56.34877","type":"journal-article","created":{"date-parts":[[2024,3,14]],"date-time":"2024-03-14T09:56:02Z","timestamp":1710410162000},"page":"jrm34877","source":"Crossref","is-referenced-by-count":0,"title":["Musician\u2019s dystonia in a percussionist \u2013 clinical video analysis and botulinum toxin intervention: a case report"],"prefix":"10.2340","volume":"56","author":[{"given":"Manuel Tom\u00e1s","family":"Farinha Caro\u00e7o","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Z\u00e3o","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00falia","family":"Ribeiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Fialho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor","family":"Milet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruna","family":"Meira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1183","published-online":{"date-parts":[[2024,3,14]]},"reference":[{"key":"51929","doi-asserted-by":"crossref","unstructured":"Albanese A, Di Giovanni M, Lalli S.
