Methods: In this prospective cohort study, patients undergoing CTR surgery of the dominant hand, between 18 and 70 years of age, with frequent use of a QWERTY keyboard and smartphone were included. A baseline Visual Analog Scale (VAS) for subjective alteration of writing and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) were collected at a maximum 3-month follow-up. Digital typing speed (word per minute, wpm) and accuracy (number of mistakes) were tested. Handwriting was assessed by means of direct supervision of one investigator. Results: Of the 30 enrolled patients, 23 (76.7%) completed the 3-month follow-up and were included in the final analysis (mean age 55 \u00b1 12.3 years). Pre- and post-surgery improvements in keyboard typing speed (14.8 \u00b1 6.8 wpm to 17.6 \u00b1 5 wpm) and mobile texting speed (16.7 \u00b1 5.9 wpm to 21.7 \u00b1 6.5 wpm) were significantly improved over time. Accuracy improved significantly only in keyboard typing, where the mean number of errors was reduced (13.1 \u00b1 8.2 to 9.9 \u00b1 5.6). QuickDASH scores decreased significantly (39.1 \u00b1 9.1 to 17 \u00b1 6). Conclusions: CTR surgery was associated with improved typing speed and reduced the number of errors (19% and \u221224%, respectively) as well as texting speed (30%). This improvement may be relevant in daily and occupational activities, as reported in the previous literature.<\/jats:p>","DOI":"10.3390\/jfmk11030281","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T15:17:52Z","timestamp":1784647072000},"page":"281","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Performance of Handwriting and Digital Typing After Carpal Tunnel Release: The TACTUS (Typing Ability in Carpal Tunnel Syndrome) Study"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4268-5186","authenticated-orcid":false,"given":"Lorenzo Alirio","family":"Diaz Balzani","sequence":"first","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"},{"name":"Research Unit of Orthopaedic and Trauma Surgery, Department of Medicine and Surgery, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6215-8645","authenticated-orcid":false,"given":"Guglielmo","family":"Torre","sequence":"additional","affiliation":[{"name":"Villa Stuart Sport Clinic, FIFA Medical Centre of Excellence, 00135 Rome, Italy"},{"name":"Department of Movement, Human and Health Sciences, University of Rome \u201cForo Italico\u201d, 00135 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2993-2181","authenticated-orcid":false,"given":"Erika","family":"Albo","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"},{"name":"Research Unit of Orthopaedic and Trauma Surgery, Department of Medicine and Surgery, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedetta","family":"Tirone","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanna","family":"Stelitano","sequence":"additional","affiliation":[{"name":"University Department of Hand Surgery & Rehabilitation, San Giuseppe Hospital, IRCCS MultiMedica Group, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9603-9045","authenticated-orcid":false,"given":"Giulia","family":"De Marco","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"},{"name":"Research Unit of Orthopaedic and Trauma Surgery, Department of Medicine and Surgery, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Capperucci","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"},{"name":"Research Unit of Orthopaedic and Trauma Surgery, Department of Medicine and Surgery, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocco","family":"Papalia","sequence":"additional","affiliation":[{"name":"Fondazione Policlinico Universitario Campus Bio-Medico, Via Alvaro del Portillo, 200, 00128 Rome, Italy"},{"name":"Research Unit of Orthopaedic and Trauma Surgery, Department of Medicine and Surgery, Universit\u00e0 Campus Bio-Medico di Roma, Via Alvaro del Portillo, 21, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4","DOI":"10.17712\/1658-3183.2112","article-title":"Pathophysiology of carpal tunnel syndrome","volume":"20","author":"Aboonq","year":"2015","journal-title":"Neurosciences"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"440","DOI":"10.1016\/j.berh.2015.04.026","article-title":"Carpal tunnel syndrome and work","volume":"29","author":"Newington","year":"2015","journal-title":"Best Pract.
