The Growing Role of Telerehabilitation and Teleassessment in the Management of Movement Disorders in Rare Neurological Diseases: A Scoping Review.

Background: People with rare neurological diseases (RNDs) often experience symptoms related to movement disorders, requiring a multidisciplinary approach, including rehabilitation. Telemedicine applied to rehabilitation and symptom monitoring may be suitable to ensure treatment consistency and personalized intervention. The objective of this scoping review aimed to emphasize the potential role of telerehabilitation and teleassessment in managing movement disorders within RNDs. By providing a systematic overview of the available literature, we sought to highlight potential interventions, outcomes, and critical issues. Methods: A literature search was conducted on PubMed, Google Scholar, IEEE, and Scopus up to March 2024. Two inclusion criteria were followed: (1) papers focusing on telerehabilitation and teleassessment and (2) papers dealing with movement disorders in RNDs. Results: Eighteen papers fulfilled the inclusion criteria. The main interventions were home-based software and training programs, exergames, wearable sensors, smartphone applications, virtual reality and digital music players for telerehabilitation; wearable sensors, mobile applications, and patient home video for teleassessment. Key findings revealed positive outcomes in gait, balance, limb disability, and in remote monitoring. Limitations include small sample sizes, short intervention durations, and the lack of standardized protocols. Conclusion: This review highlighted the potential of telerehabilitation and teleassessment in addressing movement disorders within RNDs. Data indicate that these modalities may play a major role in supporting conventional programs. Addressing limitations through multicenter studies, longer-term follow-ups, and standardized protocols is essential. These measures are essential for improving remote rehabilitation and assessment, contributing to an improved quality of life for people with RNDs.

Allogenic umbilical cord-derived mesenchymal stromal cells improve motor function in prenatal surgical repair of myelomeningocele: An ovine model study.

OBJECTIVE: To investigate the effects of an adjuvant allogenic umbilical cord mesenchymal stromal cell (UC-MSC) patch applied during fetal surgery on motor and sphincter function in the ovine MMC model. DESIGN: MMC defects were surgically created at 75 days of gestation and repaired 14 days later. POPULATION: Ovine MMC model: fetal lambs. METHODS: We compared lambs that received a UC-MSC patch with a control group of lambs that received an acellular patch. MAIN OUTCOME MEASURES: Clinical neurological assessment was performed at 2 and 24 hours of life and included determination of the Sheep Locomotor Rating scale (SLR), which has been validated in the ovine MMC model. Electrophysical examinations, spine scans and histological analyses were also performed. RESULTS: Of the 13 operated lambs, nine were born alive: five had of these had received a UC-MSC patch and four an acellular patch. At 24 hours of life, lambs in the UC-MSC group had a significantly higher score (14 versus 5, P = 0.04). Amyotrophy was significantly more common in the control group (75% versus 0%, P = 0.02). All the lambs in the control group and none of those in the UC-MSC group were incontinent. No significant differences were observed between the UC-MSC and control groups in terms of the presence of spontaneous EMG activity, nerve conduction or spinal evoked potentials. In the microscopic examination, lambs in the UC-MSC group had less fibrosis between the spinal cord and the dermis (mean thickness, 453 versus 3921 µm, P = 0.03) and around the spinal cord (mean thickness, 47 versus 158 µm, P < 0.001). Examination of the spinal cord in the area of the MMC defect showed a higher large neuron density in the UC-MSC group (14.5 versus 5.6 neurons/mm2, P < 0.001). No tumours were observed. CONCLUSIONS: Fetal repair of MMC using UC-MSC patches improves motor and sphincter function as well as spinal preservation and reduction of fibrosis.

In utero treatment of myelomeningocele with allogenic umbilical cord-derived mesenchymal stromal cells in an ovine model.

PURPOSE OF THE STUDY: The purpose of our study was to investigate the effects of ovine umbilical cord-derived mesenchymal stromal cells (UC-MSCs) seeded in a fibrin patch as an adjuvant therapy for fetal myelomeningocele repair in the ovine model. MATERIALS AND METHODS: MMC defects were surgically created at 75 days of gestation and repaired 15 days later with UC-MSCs patch or an acellular patch. At birth, motor function, tail movements, and voiding abilities were recorded. Histological and immunohistochemical analysis included study of MMC defect's healing, spinal cord, UC-MSCs survival, and screening for tumors. RESULTS: Six lambs were born alive in each group. There was no difference between the two groups on the median sheep locomotor rating score but all lambs in the control group had a score between lower than 3 compared to 50% in UC-MSCs group. There were more lambs with tail movements and voiding ability in UC-MSCs group (83% vs 0% and 50% vs 0%, respectively). gray matter area and large neurons density were higher in UC-MSCs group (2.5 vs 0.8 mm2 and 19.3 vs 1.6 neurons/mm2 of gray matter, respectively). Fibrosis thickness at the myelomeningocele scar level was reduced in UC-MSCs group (1269 µm vs 2624 µm). No tumors were observed. CONCLUSION: Fetal repair of myelomeningocele using allogenic UC-MSCs patch provides a moderate improvement in neurological functions, gray matter and neuronal preservation and prevented from fibrosis development at the myelomeningocele scar level.

Open fetal surgery for myelomeningocele repair in France.

INTRODUCTION: Open fetal myelomeningocele (MMC) surgery is currently the standard of care option for prenatal MMC repair. We described the population referred to our center and reviewed outcome after open fetal MMC repair. MATERIAL AND METHODS: All patients referred to our center for MMC were reviewed from July 2014 to June 2020. For all the patients who underwent fetal MMC repair, surgical details, maternal characteristics and data from the neonatal to the three-years-old evaluations were collected. RESULTS: Among the 126 patients referred to our center, 49.2% were eligible and 27.4% (n = 17) of them underwent fetal MMC repair. Average gestational age at fetal surgery was 24+6 weeks. There was no case of fetal complication and the only maternal complication was one case of transfusion. We recorded 70% of premature rupture of membranes and 47% of premature labor. Average gestational age at delivery was 34+2 weeks and no patient delivered before 30 weeks. There was no case of uterine scar dehiscence or maternal complication during cesarean section. After birth, 59% of the children had a hindbrain herniation reversal. At 1-year-old, 42% were assigned a functional level of one or more better than expected according to the prenatal anatomic level and 25% required a ventriculoperitoneal shunt. At 3-year-old, all the children attended school and 75% were able to walk with orthotics or independently. CONCLUSION: Open fetal surgery enables anatomical repair of the MMC lesion, a potential benefit on cerebral anomalies and motor function, with a low rate of perinatal and maternal complications.

Prevention of Neural Tube Defects by Folic Acid Supplementation: A National Population-Based Study.

Folic acid supplementation is recommended for neural tube defect prevention during pregnancy. We conducted an observational, retrospective national registry study to determine the rate of dispensing of periconceptional folic acid after prescription in a sample of French women representative of the general population. Our study population (n = 186,061) was a representative sample of the French population, recorded in the Health Data System database on pharmacy dispensing of medication and mandatory reporting of pregnancy. Between 2006 and 2016, 14.3% of pregnant women had a prescription for folic acid supplementation during the month preceding conception and for the first 12 weeks of pregnancy. Of these prescriptions, 30.9% were issued before the start of pregnancy. This percentage was lower for first pregnancies. The rate of pharmacy dispensing during the preconception period increased progressively from 3.8% to 8.3% between 2006 and 2016. In France, the rate of pharmacy dispensing of periconceptional folic acid after medical prescription is very low and does not follow international recommendations. It seems essential to implement awareness-raising policies targeting the general population and physicians regarding effective periconceptional supplementation, particularly starting in the preconception period. Clarification of international recommendations and fortification of flour could improve the efficacy of folate supplementation at population level.

Spinal lipoma of the filum terminale: review of 174 consecutive patients.

PURPOSE: Spinal lipoma of the filum terminale (LFT) is a congenital lumbosacral anomaly that can cause tethered cord syndrome. Purposes of this study are to clarify preoperative characteristics of LFT, to elucidate surgical effects, and to discuss the rationale of prophylactic surgery for LFT. METHODS: Medical data of 174 children (2008-2014) who underwent section of LFT were prospectively recorded for prevalence of symptoms, skin stigmas, and associated malformations, motivator of diagnosis, conus level, and surgical outcome. Mean age at surgery was 4.1 ± 4.2 years (37 days to 17.7 years). RESULTS: Ninety-four children (54.0 %) had skin stigmas and 60 (34.5 %) had certain perineal malformations. Seventy-nine children (45.4 %) were symptomatic. The most common motivator for diagnosis was skin stigmas (44.3 %), followed by associated malformations (33.3 %), and symptoms (20.1 %). The age at surgery was significantly older in symptomatic patients than in asymptomatic patients (p < 0.001). Surgery improved symptoms in 50 % of patients at 2.1-year follow-up period. Of 85 asymptomatic patients, all except one remained asymptomatic postoperatively and none of the symptomatic patients deteriorated. The presence of associated malformations and the conus level did not affect surgical outcome. Postoperative complications developed in nine patients (5.2 %): seven transient local problems, one definitive urological deterioration, and one transient respiratory problem. CONCLUSIONS: Surgery for LFT was a simple and safe procedure. It improved half of symptomatic patients and stopped the deterioration of the others. Even if only one of the asymptomatic patients deteriorated at maximum follow-up, the role of prophylactic surgery remains a point of discussion.

Pro and Cons of Transurethral Self-Catheterization in Boys: A Long-Term Teaching Experience in a Pediatric Rehabilitation Centre.

PURPOSE: To describe the acceptance and efficacy of clean intermittent catheterization (CIC) in the management of lower urinary tract (LUT) dysfunction regardless of the age of the children and their degree of urethral sensation. MATERIALS AND METHODS: We retrospectively evaluated boys managed with CIC at a pediatric teaching hospital between 1992 and 2014. Age, urethral sensation, acceptance, efficacy in terms of continence and preserving upper urinary tract and genitourinary complications were reviewed in the medical records. RESULTS: Sixty boys managed with CIC for LUT dysfunction due to neurological or urological disorders were identified. The median age at CIC initiation was 8.2 years (range, 1.4-18). With regard to age, CIC was well tolerated in younger boys and without genital sensation. Failure in the CIC protocol occurred within the first six months (n = 9). More boys with genital sensation were socially continent with CIC (91% versus 83%, P = .05). Vesicoureteral reflux was resolved in 69% of boys (P = .03), and hydronephrosis in 54% (P = .07). CONCLUSION: CIC was effective in terms of continence and renal protection. The procedure was feasible even in boys with preserved urethral sensation. Therapeutic education by a dedicated urotherapy nurse is the key factor in ensuring long-term CIC compliance and acceptability.
