Grafting of C7 from the nonparalyzed to the paralyzed side in patients with arm paralysis resulted in greater improvements in power, spasticity, and function at 12 months than rehabilitation therapy alone, and functional connection to the ipsilateral cerebral hemisphere developed.

Stroke is the principal cause of permanent disability in adult age, and many patients require lifelong medical treatment and care from others for their daily activities. It has enormous repercussions on the work and social lives of patients and their families and involves major economic expenditure. Post-stroke spastic upper limb is usually treated with rehabilitation, occupational therapy, and periodical injections of botulinum toxin, while surgical correction is now seldom considered. However, there has been no clinical trial to compare between surgical and toxin treatments. The primary aim of this study is to compare outcomes between surgery and a conventional approach with botulinum toxin in patients with post-stroke upper limb spasticity. A two-arm (surgical treatment [n = 22] vs. botulinum toxin [n = 22]) randomized clinical trial (RCT) will be performed to compare the efficacy of surgery with that of botulinum toxin treatment in patients with post-stroke upper limb spasticity. Data will be collected at baseline and at 6 and 12 months of follow-up on functionality, hygienic status, quality of life, sleep quality, anxiety/depression levels, and functional magnetic resonance imaging (fMRI)-measured brain activity. Healthcare and care costs will be compared between the groups. This research is set in the context of chronic diseases, aging, and functional/mobility limitations. The results can be expected to have a major impact, because the high prevalence of stroke and the severe associated disability means that an enormous number of patients can benefit from improved treatment protocols, and a more rational use of resources would yield considerable economic benefits for health and care systems. Our expectation is that outcomes would be more favorable with surgery. However, the aim is not to exclude any approach but rather to explore how the potential and indications of each treatment could be integrated within a multidisciplinary therapeutic protocol in a complementary manner.

Background Quadriceps spasticity is responsible for a gait disturbance characterized by stiff knee with reduced knee flexion during the swing phase. Selective Femoral Neurotomy induces long-term muscle relaxation via a decrease of the stretch reflex. Method Femoral nerve trunk is dissected just below the femoral crease. Motor branches to the rectus femoris and/or vastus intermedius muscles are identified using electrical stimulation combined with electromyographic recording, then partially sectioned according to an individualized preoperative chart. Postoperative rehabilitation is imperative for sustained gait improvements. Conclusion Selective Femoral Neurotomy (SFN) is a lesion-based, permanent surgical treatment of spastic stiff knee gait.

Purpose Selective dorsal rhizotomy (SDR) and intrathecal baclofen (ITB) pump placement are two surgical options in children affected by spasticity secondary to cerebral palsy 1 . The latest literature is an enlarging indication for SDR in case of ITB failure in non-ambulant patients as an alternative to pump reimplantation to reduce spasticity and facilitate patients’ care. Methods A retrospective single-center study has screened all children diagnosed with spastic tetraparesis who underwent in the last 10 years SDR and had previously ITB pump implanted. A cohort of six patients was pooled out. Furthermore, pertinent literature has been reviewed. Results Indication for pump removal was pump pocket infection, parents’ decision, and poor response to ITB. Patients’ amount of lifetime with the pump implanted has been 6.9 years. The preoperative and postoperative Ashworth scores were statistically different in both procedures ( p = 0.005 and p = 0.,02). Conclusions Only two studies investigated the pediatric population undergoing SDR in the occurrence of ITB pump removal. Authors are offering SDR to all children, regardless of GMFCS groups and previous ITB pump placement. In conclusion, SDR represents a valid tool in neurosurgeon’s hands to help ameliorate patients’ long-lasting quality of life, reducing the severity of the spasticity and leading to better management by caregivers.

Shoulder spasticity is a common consequence of upper motor neuron lesions and may be associated with soft tissue contractures, limiting functional recovery. While both cryoneurolysis and tendon lengthening procedures are used individually in refractory cases, their combined effect has not been clearly established. It is consequently necessary to assess the efficacy of combining cryoneurolysis and percutaneous pectoral tenotomy in reducing shoulder spasticity and improving passive range of motion in patients with refractory shoulder spasticity and contracture. This retrospective, single-centre cohort study included 15 adults (≥19 years) with chronic shoulder spasticity and clinically confirmed musculotendinous contracture, previously treated with botulinum toxin injections without sufficient functional response, and free of pharmacological effects (last injection >4 months prior). All patients underwent cryoneurolysis targeting motor branches to the pectoral muscles. Outcomes included Modified Ashworth Scale (MAS) and shoulder Passive Range Of Motion (PROM). The combined approach provided significant improvements in spasticity severity for shoulder flexion (p < 0.01) and abduction (p < 0.01), and significant improvements in maximum PROM for shoulder flexion (p < 0.0001) and abduction (p < 0.0001). Combining cryoneurolysis and pectoral tenotomy appears feasible, safe, and clinically beneficial in selected patients with both spasticity and tendon contracture. Cryoneurolysis addresses the neural component, while tenotomy may restore mechanical excursion. This sequential diagnostic and therapeutic approach may enhance personalized management of mixed spastic–contracture shoulder limitations and could be applicable to other joints.

Objective Intraventricular baclofen has been reported as an alternative to intrathecal baclofen for managing refractory spasticity and dystonia in some circumstances. In this report, we described a frame-based stereotactic approach for precisely positioning of the infusion catheter into the third ventricle. Material and methods High resolution contrast-enhanced anatomical MR sequences was acquired prior to surgery for pre-planning. Catheter trajectory was planned to pass from the lateral ventricle to the third ventricle through the Foramen of Monro. The surgical procedure was adapted from the frame-based deep brain stimulation surgery. The Touch-Loc kit (SceneRay, China) was used to temporarily secure the catheter in place during the surgery. From July 2022 to December 2022, three patients suffering from intractable spasticity and/or secondary dystonia received IVB successfully using the described technique. Results No severe adverse events, including death, intracranial hemorrhage, infection, catheter migration or fracture, were documented at the last follow-up (range: 12‒24 months). Transient side effects included mild nausea following the initiation of infusion or the increase in infusion rate. All three patients responded to the IVB. Conclusions The described frame-based stereotactic technique for IVB catheter implant is feasible and could be quickly mastered by neurosurgeons in related fields. Larger prospective cohorts with longer follow-up periods are necessary to further evaluate the long-term safety and efficacy of this procedure.

This study investigated the prevalence and severity of lower urinary tract symptoms (LUTS) in children with spastic cerebral palsy (SCP) and evaluated the effect of selective dorsal rhizotomy (SDR) in alleviating these symptoms. The study also explored the correlation between postoperative LUTS improvement and intraoperative electrophysiological findings. Prospective data were collected from a consecutive cohort of 247 children with SCP who underwent SDR and were retrospectively analyzed. Pre- and post-operative assessments included muscle tone, motor function, LUTS and intraoperative electrophysiology data were analyzed. Preoperatively, 94 patients (38.1%) had LUTS, and the severity of LUTS negatively correlated with motor function ( R =-0.32, P  < 0.0001). After SDR, muscle tone decreased, motor function improved ( P  < 0.0001), and LUTS resolved in 49/94 patients (52.1%). LUTS improvement correlated with a higher proportion of sensory nerves evoking anal sphincter EMG > 20µV. SDR effectively reduces spasticity, improves motor function, and alleviates LUTS in most children with SCP. Intraoperative neurophysiology may predict improvements, warranting further research.

Background Surgical selective dorsal rhizotomy (SDR) in appropriate pediatric cerebral palsy patients is an effective treatment for spasticity. However, there remains heterogeneity reported in postoperative pain management with and without opioid medication in this delicate cohort. The objective of this study was to aggregate pertinent metadata by means of systematic review to summarize all relevant postoperative pain regimens in the literature. Methods Searches of multiple electronic databases from inception to June 2024 were conducted following PRISMA guidelines. Articles were screened against pre-specified criteria. Outcomes and regimens were then summarized. Results A total of 16 cohort studies were included in this study published between 1989 and 2024. Amongst all studies, outcomes were reported for a total of 636 with median cohort age 6.3 years, and median cohort male proportion 62% was reported. Four studies reported regimens involving systemic analgesia, 8 studies reported regimens involving epidural analgesia, and the remaining 4 studies reported regimens involving intrathecal analgesia. All studies primary pain management involved opioid medication, with 8 studies having opioid medication available as indicated, 3 studies having opioid medication as a single dose, and the remaining studies having opioid medication as a continuous agent in the immediate postoperative period. Across all studies, rates of desaturations, nausea and/or vomiting, and pruritis ranged from 0 to 55%, 25 to 82%, and 15 to 70% respectively. Eleven of the 16 studies included a comparative component, demonstrating that their regimen was at least comparable to their control regimen, if not superior. Conclusions Multiple variations of postoperative pain management in pediatric cerebral palsy patients following SDR have been reported in the literature, involving systemic, epidural, and intrathecal analgesia. Concerns for adverse effects with the utilization of opioid medication has led to the trend towards multimodal pain management relying more on non-opioid medication regimens in the more recent literature.

Background Cerebral palsy (CP) is the most cause of motor dysfunction in children. Selective dorsal rhizotomy (SDR) plays a major role in long term spasticity control. However, limited data exists on the effect of SDR on postoperative spasticity treatment requirements and supraspinal effects, and the stimulation responses of dorsal nerve roots in those with CP. Methods The current study included the outcome for 35 individuals undergoing SDR for motor functional outcome, spasticity, baclofen dose changes, botulinum toxin injection frequency, and spasticity related orthopedic procedures. We also report on the stimulation responses in 112 individuals who underwent SDR at our institution. Results There was a significant difference in gross motor function measures (GMFM)-66 scores at last follow up that remained present when considering only ambulatory children but not with non-ambulatory children. Ashworth scores were significantly decreased for both upper and lower extremities after SDR at all follow up points. There was a significant decrease in Baclofen dose and botulinum toxin injections requirements after SDR, but no significant difference in the need for orthopedic intervention. A total of 5502 dorsal nerve roots were tested showing a decrease in stimulation intensity and increase in grade on the right side and for descending lumbosacral levels. Conclusions SDR improves gross motor scores during short term follow up but has additional benefits in decreasing baclofen dosing and botulinum toxin injections requirements after surgery. They stimulation responses of sectioned dorsal nerve roots adds to the limited available data and our understanding of the pathological changes that occur in CP.
