Introduction: Study of muscle tone in individuals with severe spasticity (Modified Asworth Scale – MAS:3) under general anesthesia can confirm or rule out the eventual necessity of the impending spasticity relieving ablative neurosurgery by observing the hypertonia reduction and passive range of motion expansion. Therefore, what we measure under muscle relaxants is practically a fixed deformity. Case Presentation: The study was performed on a girl with Sjögren-Larsson syndrome, presenting with icthyosis and spastic diplegia. Proposed intervention was Dorsal Rhizotomy. Under general anesthesia, with and without muscle relaxants, hypertonia was significantly reduced (MAS:1), but the angle of motion did not increase much. Conclusion: We decided not to perform such a neurosurgical procedure. In ambiguous situations, the proposed study can help in decision-making for spasticity treatment.

Abstract Purpose Investigate the effect of age category (1–9 years vs 10–18 years), sex, Gross Motor Function Classification System (GMFCS) level, and presence of dystonia on changes in eight function test parameters 24 months after selective dorsal rhizotomy (SDR). Methods Prospective, single-center study of all children aged 3–18 years with bilateral cerebral palsy with spasticity who underwent SDR at a tertiary pediatric neurosurgery center between 2012 and 2019. A linear mixed effects model was used to assess longitudinal changes. Results From 2012 to 2019, 42 children had follow-up available at 24 months. Mean GMFM-66 scores increased after SDR (mean difference 5.1 units: 95% CI 3.05–7.13, p < 0.001). Statistically significant improvements were observed in CPQoL, PEDI Self-care and Mobility, 6MWT, Gillette, and MAS scores. There was no significant difference in the improvements seen for age category, sex, GMFCS level, and presence of dystonia for most of the parameters tested (5/8, 6/8, 5/8, and 6/8 respectively). Conclusion SDR may improve gross and fine motor function, mobility and self-care, quality of life, and overall outcome based on extensive scoring parameter testing at 24 months. Atypical patient populations may benefit from SDR if appropriately selected. Multi-center, prospective registries investigating the effect of SDR are required.

Experiments were performed in eight lightly anesthetized thiopental sodium (Pentothal) cats to examine whether diaphragmatic afferents can significantly alter the neural drive to the diaphragm when the animal is exposed to lower body negative pressure. Moving-time-averaged diaphragmatic electromyograms (EMGma) were recorded and compared before and during exposure to lower body negative pressure in each of three consecutive conditions: C7 spinalization, bilateral vagotomy, and cervical dorsal rhizotomy. Application of lower body negative pressure in C7-spinalized animals resulted in a decrease in inspiratory time and peak diaphragmatic activity compared with control levels. After bilateral vagotomy, EMGma activity was prolonged with the application of lower body negative pressure. However, there was no increase in peak EMGma activity. After transection of the cervical dorsal roots subserving the phrenic nerve, the prolongation of diaphragmatic activity negative was eliminated. Therefore, we conclude that the significant increase in duration of inspiration in response to application of lower body negative pressure in the C7-spinalized, bilaterally vagotomized cat is mediated by phrenic nerve afferents.
