“…Subsequently, several articles have shown the efficacy of vo-thalamotomy for TSFD in musicians, hairdressers, watchmakers, and table tennis players. 7,9,15,19 The vo nucleus of the thalamus is a relay point in the corticobasal ganglia-thalamo-cortical circuit and a major termination site for basal ganglia outputs that control the motor cortex. Circuit abnormalities could induce impaired regulation between desired and unwanted movements, ultimately leading to dystonic movements.…”

“…Although several studies have demonstrated the high efficacy of lesioning on ventro-oral (vo) nucleus of the thalamus (vo-thalamotomy) for TSFDs, these are limited to case reports and a few small-scale studies. 7,9,14–23 We herein retrospectively report on the safety and long-term efficacy of vo-thalamotomy in 171 consecutive patients with TSFD. This is the largest case series involving follow-up study of patients who undergo vo-thalamotomy for TSFD.…”

ObjectiveTo report the safety and long-term efficacy of ventro-oral thalamotomy for 171 consecutive patients with task-specific focal hand dystonia.MethodsBetween October 2003 and February 2017, 171 consecutive patients with task-specific focal hand dystonia underwent unilateral ventro-oral thalamotomy. Etiologies included writer's cramps (n = 92), musician's dystonias (n = 58), and other occupational task-related dystonias (n = 21). The task-specific focal hand dystonia scale was used to evaluate patients' neurologic conditions (range 1–5, high score indicated a better condition). The scores before surgery; at 1 week, 3 months, and 12 months postoperatively; and the last available follow-up period were determined. Postoperative complications and postoperative recurrence were also evaluated.ResultsThe scores before surgery; at 1 week (1.72 ± 0.57, 4.33 ± 0.85 [p < 0.001]), 3 months (4.30 ± 1.06 [p < 0.001]), and 12 months (4.30 ± 1.13 [p < 0.001]); and the last available follow-up (4.39 ± 1.07 [p < 0.001]) postoperatively improved. The mean clinical follow-up period was 25.4 ± 32.1 months (range: 3–165). Permanent adverse events developed in 6 patients (3.5%). Eighteen patients developed recurrent dystonic symptoms postoperatively. Of these 18 patients, 9 underwent ventro-oral thalamotomy again, of which 7 achieved improvement.ConclusionVentro-oral thalamotomy is a feasible and reasonable treatment for patients with refractory task-specific focal hand dystonias. Prospective, randomized, and blinded studies are warranted to clarify more accurate assessment of the safety and efficacy of ventro-oral thalamotomy for task-specific focal hand dystonia.Classification of evidenceThis study provides Class IV evidence that for patients with task-specific focal hand dystonia, ventro-oral thalamotomy improves dystonia.

“…The yips has received considerable attention recently as famous professional athletes not only in golf but also in other sports, such as baseball, basketball, and tennis, have confessed that they have suffered from the yips at some point during their career. However, because clinical data are limited to few case studies 60 , 61 , evidence-based treatment for the yips has not been established yet. Although further studies are necessary, our findings indicate that athletes with yips may benefit from avoiding allocating too much attention to the affected movements and also from learning such strategies.…”

The yips, an involuntary movement impediment that affects performance in skilled athletes, is commonly described as a form of task-specific focal dystonia or as a disorder lying on a continuum with focal dystonia at one end (neurological) and chocking under pressure at the other (psychological). However, its etiology has been remained to be elucidated. In order to understand sensorimotor cortical activity associated with this movement disorder, we examined electroencephalographic oscillations over the bilateral sensorimotor areas during a precision force task in athletes with yips, and compared them with age-, sex-, and years of experience-matched controls. Alpha-band event-related desynchronization (ERD), that occurs during movement execution, was greater in athlete with yips as compared to controls when increasing force output to match a target but not when adjusting the force at around the target. Event-related synchronization that occurs after movement termination was also greater in athletes with yips. There was no significant difference in task performance between groups. The enhanced ERD is suggested to be attributed to dysfunction of inhibitory system or increased allocation of attention to the body part used during the task. Our findings indicate that sensorimotor cortical oscillatory response is increased during movement initiation in athletes with yips.

“…reported improvement in a patient with table tennis dystonia following Vo thalamotomy. [ 23 ] All these reports underscore the role of Vo thalamus as a gateway that can be manipulated to improve any TSD. We present a series of eight patients with Writer's cramp, seven of whom underwent Vo thalamotomy and one underwent GPi DBS with marked improvement in the symptoms postoperatively.…”
