Special Issue Information

Dear Colleagues,

The field of neuromodulation is constantly growing and providing new avenues for promoting function following a neurological insult or impairment. While the number of clinical trials in adults that use neuromodulation as a treatment and/or therapy greatly outweighs the number of studies in the pediatric population, the pediatric field is growing, and more studies are demonstrating the requirements and benefits of this emerging technology.

This Special Issue will delineate current areas of research in pediatric neuromodulation and disseminate their exciting findings. Additionally, this Special Issue will address the necessary next steps needed to make neuromodulation techniques accessible for the pediatric population with neurological impairments.

We welcome cutting-edge research in neuromodulation for children. 

We welcome original articles, case studies, and reviews that study any form of neuromodulation in the neurologically impaired pediatric population. The methods used may include the use of a device to alleviate symptoms, increase function, or be restorative.

Background: Limited research exists for use of transcutaneous spinal stimulation (TSS) in pediatric spinal cord injuries (SCI) to improve walking outcomes, especially in children diagnosed with SCI secondary to acute flaccid myelitis (AFM). Objective: This case series demonstrates the feasibility and efficacy of TSS paired with gait training in children diagnosed with AFM. Methods: A total of 4 participants diagnosed with incomplete SCI secondary to AFM completed 22, 2-h therapy sessions over 5–8 weeks. TSS paired with body weight-supported treadmill training (BWSTT) was provided for the first 30 min of each session. Changes in walking function were assessed through the 6 min walk test (6MWT), Timed Up and Go (TUG), 10 m walk test (10MWT), and walking index for spinal cord injury II (WISCI-II). To assess safety and feasibility, pain, adverse events, and participant and therapist exertion were monitored. Results: All participants tolerated the TSS intervention without pain or an adverse response. Changes in the 6MWT exceeded the minimal clinically important difference (MCID) for three participants and WISCI-II exceeding the minimal detectable change (MDC) for two of the participants. Conclusions: These results demonstrate that TSS is a safe and clinically feasible intervention for pediatric patients with AFM and may supplement gait-based interventions to facilitate improvements in walking function.

While neuromodulation devices for managing neurological conditions have significantly advanced, there remains a substantial gap in FDA-approved devices specifically designed for pediatric patients. Devices like deep brain stimulators (DBS), vagus nerve stimulators (VNS), and spinal cord stimulators (SCS) are primarily approved for adults, with few options for children. To meet pediatric needs, off-label use is common; however, unique challenges to pediatric device development—such as ethical concerns, small trial populations, and financial disincentives due to the limited market size—continue to hinder progress. This review examines these barriers to pediatric neuromodulation device development and FDA (Food and Drug Administration) approval, as well as the current efforts, such as FDA initiatives and consortia support, that address regulatory and financial challenges. Furthermore, we discuss pathways like the Humanitarian Device Exemptions and Real-World Evidence programs that aim to streamline the approval process and address unmet clinical needs in pediatric care. Addressing these barriers could expand access to effective neuromodulation treatments and improve patient care. Full article

Background and Purpose: activities-based locomotor training (AB-LT) is a restorative therapeutic approach to the treatment of movement deficits in people with non-progressive neurological conditions, including cerebral palsy (CP). Transcutaneous spinal stimulation (TSS) is an emerging tool in the rehabilitation of individuals with sensorimotor deficits caused by neurological dysfunction. This non-invasive technique delivers electrical stimulation over the spinal cord, leading to the modulation of spinal sensorimotor networks. TSS has been used in combination with AB-LT and has been shown to improve muscle activation patterns and enhance motor recovery. However, there are no published studies comparing AB-LT + TSS to AB-LT alone in children with CP. The purpose of this case study was to compare the impact of AB-LT alone versus AB-LT combined with TSS on functional movement and quality of life in a child with CP. Methods: A 13-year-old male with quadriplegic CP participated in this pilot study. He was classified in the Gross Motor Function Classification System (GMFCS) at Level III. He completed 20 sessions of AB-LT (5x/week), then a 2-week washout period, followed by 20 sessions of body-AB-LT + TSS. Treatment sessions consisted of 1 h of locomotor training with body weight support and manual facilitation and 30 min of overground play-based activities. TSS was applied using the RTI Xcite®, with stimulation at the T11 and L1 vertebral levels. Assessments including the Gross Motor Function Measure (GMFM), 10-m walk test (10 MWT), and Pediatric Balance Scale (PBS) were performed, while spatiotemporal gait parameters were assessed using the Zeno Walkway®. All assessments were performed at three time points: before and after AB-LT, as well as after AB-LT + TSS. OUTCOMES: After 19/20 sessions of AB-LT alone, the participant showed modest improvements in the GMFM scores (from 86.32 to 88), 10 MWT speed (from 1.05 m/s to 1.1 m/s), and PBS scores (from 40 to 42). Following the AB-LT combined with TSS, scores improved to an even greater extent compared with AB-LT alone, with the GMFM increasing to 93.7, 10 MWT speed to 1.43 m/s, and PBS to 44. The most significant gains were observed in the GMFM and 10 MWT. Additionally, improvements were noted across all spatiotemporal gait parameters, particularly at faster walking speeds. Perhaps most notably, the child transitioned from the GMFCS level III to level II by the end of the study. Discussion: Higher frequency and intensity interventions aimed at promoting neuroplasticity to improve movement quality in children with CP are emerging as a promising alternative to traditional physical therapy approaches. This case study highlights the potential of TSS to augment neuroplasticity-driven treatment approaches, leading to improvements in neuromotor function in children with CP. These findings suggest that TSS could be a valuable addition to rehabilitation strategies, warranting further research to explore its efficacy in larger populations. Full article
