Other treatments

Regarding unusual treatment methods for tics, Murakami et al. \citep{Murakami2019} describe the use of oral splints in 22 patients with TS. Tic decrease was noted in the vast majority of cases and occurred almost instantaneously. The authors suggest a placebo effect and/or a sensory trick as mechanism of action. In any case, the major question here remains how and if such an intervention can work long term and without impairing daily functioning, especially speech.  
 
A pilot study evaluated the efficacy of a resource activation program as an alternative intervention for children and adolescents (n=24) with tic disorders \citep{31207850}. Their preliminary results suggests that after 16 treatment sessions, tics were significantly diminished using the YGTSS and other tic-related measures. Larger cohorts and longer follow-up will hopefully establish whether this approach might become an alternative or adjunct to established CBT approaches for treating tics such as HRT and ERP.
