ABSTRACT

Background and purpose:

Quadriceps femoris muscle spasticity is commonly measured by the Wartenberg pendulum test. It is generally assumed that lower values of the number of swings of the leg and lower relaxation indexes are associated with higher muscle tone and more spasticity. Still, there is incoherence regarding the test’s applications with various body positions and starting mechanisms. This study aims to investigate the influence of body position, leg dominance, and automatic leg-releasing mechanism on muscle tone measured by pendulum test in healthy population whose muscle tone is often compared to the spastic muscle tone of patients with neurologic disorders. 

. Methods:

15 healthy adults (age: 19-32 years, 9 males, 6 females) participated in this study. A Zebris 3D ultrasound-based motion analysis system was used to record kinematic data during the pendulum test. The number of swings of the leg and the relaxation index were computed from the collected data. The pendulum test was completed in eight conditions: in supine and semi-supine positions on the dominant and non-dominant leg separately and with investigator-release and automata-release mechanisms. Paired t-tests and Wilcoxon test with the significance level of .05 were applied in comparison of pairs of the pendulum test condition.

. Results:

1) Applying automata-release mode, in the non-dominant leg the number of swings (p=0.03) and the relaxation index (p<0.001) were significantly higher in semi-supine than in supine position. 2) The non-dominant leg had significantly more swings than the dominant leg in both body positions with automata-release mode (p=0.009, p<0.001). In investigator-release mode this occurred in supine position (p<0.001). 3). Regarding the number of swings in investigator-release versus automata-release mode, no significant differences were found in any test condition, but the relaxation index showed significant difference for the non-dominant leg (p=0.01, p=0.009). 4) The values of the relaxation index didn’t support in all test conditions the results what the number of swings provided about the muscle tone. In automata-release mode, the dominant leg has a lower number of swings and a higher relaxation index than the non-dominant leg.

. Conclusion:

The effect of body position on the quadriceps muscle tone can be assessed by applying the pendulum test with an automatic leg-releasing mechanism even when the application of conventional investigator-release mode does not show a significant effect. The pendulum test is more sensitive to assess spasticity with automatic-release than with investigator-release mode.

ABSTRACT

Objective: To identify potential barriers and obstacles preventing clinicians from adopting ultrasound for spasticity management. Design: A prospective, cross-sectional national survey. Setting: Web-based platform. Participants: Thirty-six physicians and surgeons from across Canada. Interventions: Survey completion. Main Outcome Measures: The use of ultrasound in clinical spasticity practice, perceived barriers, and risks associated with its implementation. Results: In total, 36 Canadian physicians and surgeons responded. A total of 91% reported using the US in their practice. Nearly all of them used ultrasonography (US) to guide injections and reported using more than 1 guidance technique for their injections. Less than half of the survey respondents reported using the US for muscle architecture assessment or longitudinal evaluation of muscle echo intensity. A total of 47% of survey respondents reported that they believe there are disadvantages associated with US use in spasticity practice. Disadvantages included increased time requirements resulting in discomfort for the injector and patient, the risk of infection after the procedure, and the risk of needle-stick injury. The most important barrier identified was the increased time demands of US compared with other guidance techniques. Other barriers included a lack of feedback on identifying a spastic muscle compared with electrical guidance techniques, a lack of additional remuneration to complete injections under ultrasound guidance, and a lack of adequate training. Conclusions: Future educational efforts should address clinicians' lack of familiarity with US purposes outside of injection guidance. This survey has highlighted the need for a curriculum shift in spasticity education to improve physician's scanning and injection technique, to address concerns about increased time requirements for injecting under ultrasound guidance and to address perceived disadvantages from clinicians.

ABSTRACT

OBJECTIVES: The aim of this study was to explore the factors that could predict long term clinical outcomes in SA. METHODS: A retrospective study was conducted wherein SA patients undergoing surgical resection with a minimum follow up of 12 months were included in this study. Modified Mccormick Scale (MMS) was utilized to record the neurological status of the patients both preoperatively and at last follow up. Outcomes were assessed as: long term neurological status, that is final MMS grade and neurological deterioration, defined as increase in MMS score as compared to preoperative MMS score. Survival analysis was performed using the kaplan meier curves. RESULTS: 71 patients were included in this study with mean age of 33.07years. At a mean follow up of 57 months, preoperative MMS was the single independent predictor for moderate-severe neurological deficit (MMS III to V) on multivariate analysis (OR: 30.2, p < 0.001) and had an outstanding AUC of 0.91. Six patients had neurological deterioration at long term follow up. Absence of spasticity (p = 0.028), thoracic-thoracolumbar tumors (p = 0.006), low MMS score (p = 0.01) and hypointense T1 weighted MRI (p = 0.009) were significant predictors of long term neurological deterioration. The median overall survival was 48 months and was significantly higher in low grade tumors (p < 0.001). CONCLUSION: The study highlights the efficacy of clinical features as a predictor of long term functional outcomes in SA patients. Role of spasticity as a prognostic factor was explored for the first time in this study.

ABSTRACT

BACKGROUND: Extracorporeal shockwave therapy (ESWT) has been proven beneficial for post-stroke spasticity (PSS) of ankle plantar flexor muscles. This study aims to investigate the dose-response effectiveness of focused-ESWT and the duration of its effect on the treatment of ankle PSS in stroke patients. METHODS: In this double-blinded randomized controlled trial, stroke patients diagnosed with PSS in the ankle plantar flexor muscles were randomly assigned to two groups. The experimental group received double-dose ESWT (4000 pulses per session) targeting spastic calf muscles, while the control group received half the dose (2000 pulses per session). Both groups underwent four sessions over two weeks. The outcomes, including modified Ashworth Scale (MAS), modified Tardieu Scale (MTS), passive range of motion (PROM) of the ankle, Timed Up and Go (TUG) Test, Barthel index and strain elastography were evaluated at baseline, 1st, 4th, 12th, and 24th week after ESWT. RESULTS: Within-group analysis revealed significant improvements in MAS, PROM, TUG Test, and Barthel index for the double-dose ESWT group and improvements in Barthel index for the control group. Between-group analysis revealed greater improvements in TUG Test, Barthel Index and strain elastography for the double-dose ESWT group. Generalized estimating equations analysis indicated that the double-dose ESWT group achieved superior outcomes in the TUG Test, Barthel Index, and strain elastography across various time points and groups. CONCLUSIONS: Double-dose ESWT showed better functional improvement and elastography compared to the control group. ESWT demonstrated dose-response effectiveness for PSS of ankle-equinus. TRIAL REGISTRATION: NCT05878223.

ABSTRACT

OBJECTIVE: Myelomeningocele (MMC), a congenital neural tube defect, is the most common developmental anomaly of the central nervous system (CNS). Spasticity is among the main disabling factors in these patients, affecting up to 1/5 of children. The purpose of this article is to review the current knowledge regarding spasticity in MMC patients, mainly focusing on its manifestations and management. METHODS: A literature search was conducted using the PubMed database for the terms "myelomeningocele" and "spasticity." Data were collected by 5 independent investigators and then synthesized in a scoping format. RESULTS: Causes of spasticity in these patients include hydrocephalus, tethered cord syndrome (TCS), syringomyelia, CNS infection, and associated congenital brain and spine anomalies. Clinical manifestations include limb spasticity and neurogenic bladder. Spasticity primarily affects muscles below the neurological level and contributes to gait impairment. Besides walking ability, spasticity also severely affects functional mobility in general, self-care, and quality of life. The majority of MMC patients experience neurogenic bladder. Treatment of spasticity can be symptomatic or target its cause. Medical and surgical options are available for both limb and bladder spasticity. Regular physiotherapy and orthotics are used to prevent contractures and the early introduction of orthoses is the cornerstone of a gait training program. Neurosurgical treatment options for spasticity include nonablative and ablative procedures such as selective dorsal rhizototmy. The urodynamic pattern guides treatment strategies, with intermittent catheterization being the best treatment option for patients with underactive detrusor and overactive sphincter muscles. CONCLUSION: Given the particularities of spasticity in MMC patients, a multidisciplinary team approach and early rehabilitation programs are keys for their optimal management.

ABSTRACT

BACKGROUND AND PURPOSE: Botulinum neurotoxin type A1 (BoNT/A) is one of the most potent neurotoxins known. At the same time, it is also one of the safest therapeutic agents used for the treatment of several human disorders and in aesthetic medicine. Notwithstanding great effectiveness, strategies to accelerate the onset and prolong BoNT/A action would significantly ameliorate its pharmacological effects with beneficial outcomes for clinical use. EXPERIMENTAL APPROACH: Here, we combined BoNT/A with two fast-acting inhibitors of excitation-contraction coupling inhibitors (ECCI), either the µ-conotoxin CnIIIC or dantrolene, and tested the effect of their co-injection on a model of hind-limb paralysis in rodents using behavioural, biochemical, imaging and electrophysiological assays. KEY RESULTS: The BoNT/A-ECCI combinations accelerated the onset of muscle relaxation. Surprisingly, they also potentiated the peak effect and extended the duration of the three BoNT/A commercial preparations OnabotulinumtoxinA, AbobotulinumtoxinA and IncobotulinumtoxinA. ECCI co-injection increased the number of BoNT/A molecules entering motoneuron terminals, which induced a faster and greater cleavage of SNAP-25 during the onset and peak phases, and prolonged the attenuation of nerve-muscle neurotransmission during the recovery phase. We estimate that ECCI co-injection yields a threefold potentiation in BoNT/A pharmacological activity. CONCLUSIONS AND IMPLICATIONS: Overall, our results show that the pharmacological activity of BoNT/A can be combined and synergized with other bioactive molecules and uncover a novel strategy to enhance the neuromuscular effects of BoNT/A without altering the neurotoxin moiety or intrinsic activity, thus maintaining its exceptional safety profile.

ABSTRACT

BACKGROUND: Children with cerebral palsy often have neurogenic bladders. Bladder function is further affected by complex medical management and multifactorial disease processes, leading to worsened function and poorer quality of life. Intrathecal baclofen (ITB) therapy has been used to treat hypertonia and spasticity, but implications in neurogenic bladder management have not been well described. OBSERVATIONS: A 20-year-old female with a history of cerebral palsy and neurogenic bladder treated with sacral neuromodulation underwent ITB therapy and subsequently experienced improvement in bladder control, obviating the need for bladder stimulator use. LESSONS: ITB improves hypertonia and can effectively obviate the need for neurostimulation to treat neurogenic bladder in patients with cerebral palsy. Further research is necessary to discern mechanisms. https://thejns.org/doi/10.3171/CASE24364.

ABSTRACT

INTRODUCTION: Patients managed in the Pediatric Palliative Care Integral Unit (PPCIU) have serious neurological conditions that involve significant damage at central nervous system level. The movement disorder is a very common clinical problem and for the patients where an adequate control of muscle tone is not achieved with usual techniques or drugs, intrathecal baclofen therapy (IBT) should be considered. MATERIALS AND METHODS: Descriptive retrospective study based on the review of clinical records of patients who received IBT being followed by the PPCIU of Madrid Autonomous Region in the timeframe between September 2012 and February 2021. RESULTS: IBT was implanted in 8 patients affected by infantile cerebral palsy (ICP) with a Gross Motor Function Scale (GMFCS) IV-V, 3 patients was a Pantothenate kinase deficit-associated neurodegeneration (PKAN), 2 had Acquired Brain Damage, and the remaining 3 had, respectively, 2 glutaric aciduria type I (GA-1), and poly-malformative syndrome. In all patients we observed a period of clinical stability after IBT, we call this period "honeymoon". Two patients died while in the honeymoon period, at 24.9 and 19.6 months from implantation of the pump; the median of duration of the honeymoon period in the remaining 14 was 14.4 months (IQ: 8.3-25.8). CONCLUSIONS: IBT was not only used in patients with non-progressive diseases, but also in the group of patients with neurodegenerative or progressive diseases. In all of them, after implantation of the device, we have objectified a period of clinical stability and a better control of muscle tone disorders.

ABSTRACT

OnabotulinumtoxinA (onabotA) is approved in the US for 12 therapeutic indications. Real-world data on onabotA multi-indication use are limited, often leading to delayed or reduced treatment. This study provides real-world evidence on the safety of onabotA when treating multiple indications concomitantly. SYNCHRONIZE was a multicenter, retrospective, chart-review study evaluating onabotA's safety for adults treated for ≥2 therapeutic indications within a 3-month period. The primary outcome was treatment-emergent adverse events (TEAEs) within 6 months post-treatment. A total of 279 patients were included. The most common concomitant indications treated were cervical dystonia and chronic migraine (43.4%). The average 3-month cumulative dose for multiple indications was 282.2 U. The treatment interval for multiple indications was ≤24 h for most patients (62.4%). Overall, 28.7% of patients reported ≥1 TEAE with no apparent trends in TEAEs and dose interval or cumulative dose. Reported TEAEs included UTI (5.7%), neck pain (5.0%), and headache (4.3%). No patient had a lack of effect according to clinical objective measurements. SYNCHRONIZE described the real-world safety of onabotA for patients treated concomitantly for ≥2 indications within a 3-month period. TEAEs were generally consistent with the known safety profiles of individual indications. No new safety signals were identified).

ABSTRACT

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.

ABSTRACT

PURPOSE: A comprehensive understanding of neural distribution within the vastus medialis is crucial for the effective administration of botulinum neurotoxin injections to manage spasticity. The aim of this study was to develop an anatomically informed approach to guide the administration of botulinum neurotoxin injections into the vastus medialis muscle. METHODS: Using a modified Sihler's method, we examined the vastus medialis muscles (20 specimens) to delineate the distribution of nerves relative to a transverse line extending from the anterior superior iliac spine to the base of patella. The vastus medialis muscle was divided into 10 areas from top to bottom. Then, using two fresh cadavers, ultrasonography-guided injections were performed based on the distribution of nerves within the vastus medialis. Each specimen was subsequently dissected to verify if the dye was accurately directed to the most densely innervated regions of the vastus medialis and to assess the precision of the injections. RESULTS: The intramuscular nerve distribution within the vastus medialis muscle showed distinct patterns, particularly in areas between 6 and 9. Four injections were successfully administered on each side, targeting the regions between 6 and 9 of the vastus medialis. Upon dissection of the cadavers, the dye was found to be distributed along the muscle fiber. CONCLUSION: We recommend targeting botulinum neurotoxin injections toward regions displaying a prominent nerve distribution, specifically focusing on areas between 6 and 9. By adhering to these guidelines, clinicians can minimize doses and mitigate potential adverse effects, such as gait disturbances, antibody development, and bruising, resulting from multiple injections. Furthermore, these findings can be incorporated into electromyography practices.

ABSTRACT

Spasticity management should be provided within the context of a comprehensive person-centered rehabilitation program. Furthermore, active goal setting for specific spasticity interventions is also important, with a well-established "more is better" approach. It is critical to consider adjunctive therapy and multimodal approaches if patients are not attaining their treatment goals. Often used interchangeably, there may be confusion between the terms adjunctive and multimodal therapy. Yet it is imperative to understand the differences between these approaches to achieve treatment goals in spasticity management. Addition of a secondary pharmacologic or non-pharmacologic treatment to optimize the efficacy of the initial modality, such as adding electrical stimulation or casting to BoNT-A, is considered an adjunctive therapy. Adjunctive therapy is time-specific and requires the added therapy be initiated within a specific period to enhance the primary treatment; usually within 2 weeks. Multimodal therapy is an integrated, patient-centric program of pharmacologic and non-pharmacologic strategies utilized in a concurrent/integrated or sequential manner to enhance the overall treatment effect across a variety of spasticity-associated impairments (e.g., neural and non-neural components). Moreover, within a multimodal approach, adjunctive therapy can be used to help enhance the treatment effect of one specific modality. The objectives of this paper are to clarify the differences between adjunctive and multimodal therapies, provide a brief evidence-based review of such approaches, and highlight clinical insights on selecting multimodal and adjunctive therapies in spasticity management.

ABSTRACT

Neuromuscular inhibitors have been quickly advanced from being used only for aesthetic purposes to being used as a treatment for musculoskeletal pain and muscle spasticity. This phenomenon stems from the diminished force exerted by muscles, which are essential for bone remodeling. In this context, it is hypothesized that botulinum toxin (BTX) might exert a direct influence on bone resorption. Although such treatments have the potential to provide patients with significant relief, bone loss occurring due to elective muscle paralysis has yet to be examined in clinical trials. The disuse model resulting from spinal cord injury, characterized by the absence of ground reaction and muscle forces, provides an ideal context for exploring the skeletal ramifications of intramuscular BTX injection. This approach enables an investigation into the intricate interplay between muscle and bone, encompassing the impact of spasticity on bone preservation, the potential positive and negative outcomes of BTX on bone metabolism, and the involvement of the autonomic nervous system in bone remodeling regulation. This paper presents a narrative review of research findings on the disturbance of the typical balance between muscles and bones caused by acute muscle paralysis from BTX, resulting in osteopenia and bone resorption.

ABSTRACT

Background: In healthy subjects, repetitive transcranial magnetic stimulation (rTMS) targeting the primary motor cortex (M1) demonstrated plasticity effects contingent on electroencephalography (EEG)-derived excitability states, defined by the phase of the ongoing sensorimotor µ-oscillation. The therapeutic potential of brain state-dependent rTMS in the rehabilitation of upper limb motor impairment post-stroke remains unexplored. Objective: Proof-of-concept trial to assess the efficacy of rTMS, synchronized to the sensorimotor µ-oscillation, in improving motor impairment and reducing upper-limb spasticity in stroke patients. Methods: We conducted a parallel group, randomized double-blind controlled trial in 30 chronic stroke patients (clinical trial registration number: NCT05005780). The experimental intervention group received EEG-triggered rTMS of the ipsilesional M1 [1,200 pulses; 0.33 Hz; 100% of the resting motor threshold (RMT)], while the control group received low-frequency rTMS of the contralesional motor cortex (1,200 pulses; 1 Hz, 115% RMT), i.e., an established treatment protocol. Both groups received 12 rTMS sessions (20 min, 3× per week, 4 weeks) followed by 50 min of physiotherapy. The primary outcome measure was the change in upper-extremity Fugl-Meyer assessment (FMA-UE) scores between baseline, immediately post-treatment and 3 months' follow-up. Results: Both groups showed significant improvement in the primary outcome measure (FMA-UE) and the secondary outcome measures. This included the reduction in spasticity, measured objectively using the hand-held dynamometer, and enhanced motor function as measured by the Wolf Motor Function Test (WMFT). There were no significant differences between the groups in any of the outcome measures. Conclusion: The application of brain state-dependent rTMS for rehabilitation in chronic stroke patients is feasible. This pilot study demonstrated that the brain oscillation-synchronized rTMS protocol produced beneficial effects on motor impairment, motor function and spasticity that were comparable to those observed with an established therapeutic rTMS protocol.

ABSTRACT

Objective: To demonstrate the long-term efficacy of repeated botulinum toxin A injections into the same muscles for ameliorating lower limb spasticity and gait function. Design: Single-case study. Patient: A 36-year-old woman with right cerebral haemorrhage received her first botulinum toxin A injection 1,296 days after onset. The patient underwent 30 treatments over 12 years after the first injection to improve upper and lower limb spasticity and abnormal gait patterns. The mean duration between injections was 147 days. Methods: The Modified Ashworth Scale, passive range of motion, gait velocity, and degree of abnormal gait patterns during treadmill gait were evaluated pre-injection and at 2, 6, and 12 weeks after every injection. Results: The follow-up period showed no injection-related adverse events. Comfortable overground gait velocity gradually improved over 30 injections. The Modified Ashworth Scale and passive range of motion improved after each injection. Pre-injection values of the degree of pes varus, circumduction, hip hiking, and knee extensor thrust improved gradually. However, the degree of contralateral vaulting, excessive lateral shift of the trunk, and insufficient knee flexion did not improve after 30 injections. Conclusion: Repeated botulinum toxin A injections effectively improve abnormal gait patterns, even when a single injection cannot change these values.


Botulinum toxin A (BoNTA) is used to treat spasticity in the arms and legs of adult patients. We report a case of a woman who was treated with BoNTA 30 times over 12 years to improve limb spasticity and abnormal gait patterns. The range of motion improved after each injection, and some other features of her gait improved gradually. We did not observe any injection-related adverse events during the follow-up period. We conclude that repeated BoNTA injections can effectively improve some abnormal gait patterns and comfortable overground gait velocity, even when a single injection cannot change these values. Cumulative effects were also shown. The combination of BoNTA and rehabilitation may lead to better results.

ABSTRACT

Objective: To assess the reliability and validity of the Chinese version of the Selective Control Assessment of the Lower Extremity (SCALE) in children with spastic cerebral palsy (CP). Methods: Forty-five children with spastic CP (mean age 7.29 years, SD 2.87 years, rang 4-16 years) were recruited. Internal consistency was measured using Cronbach's α, while test-retest and inter-rater reliability were evaluated using intra-class correlation coefficients (ICC). Construct validity was established through correlation and confirmatory factor analyses. Discriminative validity was assessed by comparing SCALE scores across varying GMFCS levels. Results: The Chinese version of SCALE demonstrates high internal consistency (Cronbach's α = 0.91) and good reliability with ICCs exceeding 0.76 for test-retest and inter-rater assessments. It shows significant correlations with GMFCS (r = -0.76, p < 0.001) and Fugl-Meyer scales (r = 0.79, p < 0.001), confirming its validity. Confirmatory factor analysis supports a well-fitting model (χ 2/df = 1.58, RMSEA = 0.08, SRMR <0.001, GFI = 0.98, AGFI = 0.90, CFI = 0.99, TLI = 0.98), with the latent variable's AVE at 0.59 and CR at 0.88. Discriminative validity is evident in significant differences across GMFCS levels (p < 0.001), notably between levels I and II, I and III, and I and IV (p < 0.05). Conclusion: The Chinese version of SCALE shows good reliability and validity for assessing lower limb selective movement control in children with spastic cerebral palsy in China.

ABSTRACT

Hydrocephalus is a common comorbidity associated with brain injuries, including cerebral palsy (CP). In CP, hydrocephalus typically presents in infancy or early childhood. This report describes a patient in their mid 20 s with mixed dyskinetic-spastic CP with adult-onset hydrocephalus of unknown cause initially presenting with new-onset bilateral lower extremity spasms. Multiple interventions were trialed, including ischial bursal steroid injections, botulinum toxin injections, trigger point injections, multiple oral medications, and physical and massage therapies without benefit. Given lack of treatment response, imaging of the neuraxis was obtained. Magnetic resonance imaging (MRI) of the brain demonstrated new diffuse moderate ventriculomegaly compared to prior MRI. Ophthalmologic evaluation demonstrated papilledema, and opening pressure on lumbar puncture was elevated to 44 mmHg H2O. The patient underwent ventriculoperitoneal shunt placement with rapid and near-resolution of their spasms and pain. This patient represents a unique case of new-onset hydrocephalus in an adult with CP. To ensure appropriate and timely diagnosis and treatment, individuals with neurologic conditions such as CP should have ongoing surveillance and comprehensive evaluation for any neurologic or functional changes, including changes in baseline tone. Future research is needed to better understand if adults with CP are at higher risk for the development of hydrocephalus in adulthood.

ABSTRACT

BACKGROUND: Approximately 4.4 million people in England (8% of the total population) are living with a long-term neurological condition. Within this group of vulnerable individuals, there will be individuals living with severe spasticity that requires regular outpatient treatment with botulinum toxin injection. The closure of outpatient spasticity services during the pandemic impacted individuals who required spasticity treatment and their carers, as well as the specialist clinicians responsible for service delivery. OBJECTIVES: We aimed to gain insight into the experiences of individuals living with spasticity, their carers and a clinical spasticity service lead during the pandemic, and to reflect on potential learning for the future. METHODS: A qualitative study was designed using semi-structured interviews conducted by telephone. Participants comprised patients living with a long-term neurological condition who attended outpatient spasticity clinics before the start of the pandemic in England, primary carers who accompanied patients attending these clinics and a clinical spasticity service lead. Data were audio recorded, transcribed, anonymised and coded. Data analysis utilised the One Sheet of Paper thematic approach to identify themes, which were discussed and analysed by the interdisciplinary research team and two patient and carer participants. RESULTS: Out of the 11 participants recruited, aged 36-77 years, seven comprised people living with spasticity related to a long-term neurological condition, three were carers and one was a clinical spasticity service lead. Six participants were male and five were female. Among the participants, four were stroke survivors, two were living with spinal cord injury and one was living with multiple sclerosis. Analysis revealed six major themes: experience of living with spasticity during the pandemic; impact of the pandemic on patient, carer and clinician health; access to and experience of outpatient clinic appointments; coping strategies during the pandemic; system improvements; and learning from the pandemic period. CONCLUSION: These findings contribute research knowledge to a very limited research knowledge base and suggest that there is scope for improving system and service delivery through the allocation of research funding to senior clinicians working in this specialist area.

ABSTRACT

Post-stroke spasticity and contracture remain prevalent and pose significant challenges in stroke rehabilitation. While non-surgical management is the mainstay, surgical reconstruction offers a valuable adjunct when conservative measures are exhausted. This clinical review article provides an overview of surgical reconstruction for limb spasticity and contracture following adult stroke, encompassing the rationale and specifics of these interventions. It highlights the underutilization of surgical reconstruction in rehabilitation of adult stroke patients with spasticity and contracture, and the importance of multidisciplinary collaboration including surgeons in stroke rehabilitation to optimize functional outcomes.

ABSTRACT

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.
