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). METHODS. 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.
