Purpose . To investigate the acceptability, efficacy, and effect duration of translingual neurostimulation (TLNS) plus standard therapeutic exercise program (TEP) to improve motor skills in children with cerebral palsy (CP).Me thods. Participants aged 2–17 years (n = 134) diagnosed with spastic diplegia CP with coordination and mobility symptoms were enrolled at Sestroretsk City Hospital № 40. Participants were offered one of two treatment regimens: either TEP plus TLNS with the Portable Neuromodulation Stimulator (PoNS™) – experimental arm or TEP alone (control).The treatment course continued for ten days (2 weeks, excluding two weekend days). In the experimental group and TEP, TLNS was applied twice a day, 20 minutes each during exercises, morning, and afternoon, at least 3 hours between sessions. Assessments before and after therapy courses measured spasticity, balance, and motor skills. Either treatment could be repeated several times (6–12 months between courses). All children were assessed before and after a course round of therapy using standard scales for spasticity, balance, and motor skills (Ashworth scale, Berg scale, Gross Motor Function Classification System, Functional Movement Screen). Results: Both groups of patients showed improvement; however, the improvement was significantly more significant in the experimental group across all scales, observed in all ages, and largely sustained for 6–12 months.Conclusions . TLNS plus TEP can be considered as a novel and promising strategy to improve neurorehabilitation outcomes in children with CP, offering broad implications for the development and use of TLNS in CP.
