Abstract
INTRODUCTION OnabotulinumtoxinA treatment for spasticity varies according to numerous factors and is individualized to meet treatment goals. OBJECTIVE To explore real-world onabotulinumtoxinA utilization and effectiveness in patients with lower limb spasticity from the Adult Spasticity International Registry (ASPIRE) study. DESIGN Two-year, multicenter, prospective, observational registry (NCT01930786). SETTING Fifty-four international clinical sites. PATIENTS Adults (naïve or non-naïve to botulinum toxin[s] treatment for spasticity, across multiple etiologies) with lower limb spasticity related to upper motor neuron syndrome. INTERVENTIONS OnabotulinumtoxinA administered at the clinician's discretion. MAIN OUTCOME MEASURES OnabotulinumtoxinA treatment utilization, clinician- and patient-reported satisfaction. RESULTS In ASPIRE, 530 patients received ≥1 onabotulinumtoxinA treatment for lower limb spasticity (mean age, 52 years; stroke, 49.4%; multiple sclerosis, 20.4%). Equinovarus foot was treated most often (80.9% of patients), followed by flexed knee (26.0%), stiff extended knee (22.5%), and flexed toes (22.3%). OnabotulinumtoxinA doses ranged between 10 and 1100 U across all presentations. Electromyography (EMG) was most commonly used for injection localization (≥41.1% of treatment sessions). Despite low patient response on the satisfaction questionnaire, clinicians (94.6% of treatment sessions) and patients (84.5%) reported satisfaction/extreme satisfaction that treatment helped manage spasticity, and clinicians (98.3%) and patients (91.6%) would probably/definitely continue onabotulinumtoxinA treatment. These data should be interpreted with care. Twenty-one adverse events (AEs) in 18 patients (3.4%) were considered treatment-related. Sixty-seven patients (12.6%) reported 138 serious AEs; 3 serious AEs in two patients (0.4%) were considered treatment-related. No new safety signals were identified. CONCLUSIONS ASPIRE provides long-term observational data on the treatment of lower limb spasticity with onabotulinumtoxinA. Real-world data from this primary analysis can help to guide the clinical use of onabotulinumtoxinA to improve spasticity management.

Abstract
Background: Botulinum toxin-A is a well-established treatment for adult and pediatric spastic paresis and cervical dystonia. While guidelines and approved labels indicate that treatment should not occur more frequently than every 12 weeks, studies and real-world evidence show that the timing of symptom recurrence between treatments may vary. Methods: We report retreatment criteria and response duration (retreatment intervals) from four pivotal, double-blind, placebo-controlled studies with open-label extensions involving patients treated with abobotulinumtoxinA (aboBoNTA) for upper limb (NCT01313299) or lower limb (NCT01249404) spastic paresis in adults, lower limb spastic paresis in children (NCT01249417), and cervical dystonia in adults (NCT00257660). We review results in light of recently available preclinical data. Results: In spastic paresis, 24.0-36.9% of upper limb patients treated with aboBoNTA and 20.1-32.0% of lower limb patients did not require retreatment before 16 weeks. Moreover, 72.8-93.8% of aboBoNTA-treated pediatric patients with lower limb spastic paresis did not require retreatment before 16 weeks (17.7-54.0% did not require retreatment before 28 weeks). In aboBoNTA-treated patients with cervical dystonia, 72.6-81.5% did not require retreatment before 16 weeks. Conclusion: AboBoNTA, when dosed as recommended, offers symptom relief beyond 12 weeks to many patients with spastic paresis and cervical dystonia. From recently available preclinical research, the amount of active neurotoxin administered with aboBoNTA might be a factor in explaining this long duration of response.

High clinician- and patient-reported satisfaction with individualized onabotulinumtoxinA treatment for spasticity across several etiologies from the ASPIRE study. Toxicon X 2020; 7:100040. [PMID: 32875289 PMCID: PMC7452133 DOI: 10.1016/j.toxcx.2020.100040] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2019] [Revised: 04/23/2020] [Accepted: 05/14/2020] [Indexed: 11/30/2022] Open
Abstract
Etiology-specific onabotulinumtoxinA utilization to manage spasticity is largely unknown. In this 1-year interim analysis, we evaluated real-world onabotulinumtoxinA utilization and effectiveness across several etiologies from the Adult Spasticity International Registry (ASPIRE) study. ASPIRE is a multicenter, prospective, observational registry (NCT01930786) examining stroke, multiple sclerosis [MS], cerebral palsy [CP], traumatic brain injury [TBI], and spinal cord injury [SCI] patients with spasticity treated with onabotulinumtoxinA at the clinician's discretion. Assessments included onabotulinumtoxinA utilization (each session), clinician (subsequent session)/patient (5±1 weeks post-treatment) satisfaction, and the Disability Assessment Scale (DAS; subsequent session). 730 patients received ≥1 onabotulinumtoxinA treatment, with 37% naïve to botulinum toxin(s) for spasticity. The most common etiology was stroke (n=411, 56%), followed by MS (N=119, 16%), CP (N=77, 11%), TBI (N=45, 6%), and SCI (N=42, 6%). The total body mean cumulative dose (±SD) of onabotulinumtoxinA per session ranged from 296 U (±145) in CP to 406 U (±152) in TBI. The most commonly treated upper limb presentations were clenched fist (stroke, MS, and SCI), flexed wrist (CP), and flexed elbow (TBI). Equinovarus foot was the most commonly treated lower limb presentation in all etiologies. Stroke patients showed improved DAS scores for nearly all subscales in both limbs, indicative of improved global function. All etiologies showed improved lower limb mobility DAS scores. Across all sessions, clinicians (range: 87.4% [SCI]-94.2% [CP]) and patients (range: 67.6% [TBI]-89.7% [SCI]) reported extreme satisfaction/satisfaction that onabotulinumtoxinA helped manage spasticity, and clinicians (range: 94.6% [TBI]-98.8% [CP]) and patients (range: 88.4% [stroke]-91.2% [TBI]) would definitely/probably continue treatment. Treatment-related adverse events (TRAEs) and treatment-related serious adverse events (TRSAEs) were reported as follows: stroke: 10 TRAEs (2.2% patients), 3 TRSAEs (0.5%); MS: 5 TRAEs (4.2%), 0 TRSAEs; CP: 0 TRAEs, 0 TRSAEs; TBI: 1 TRAEs (2.2%), 0 TRSAEs; SCI: 0 TRAEs, 0 TRSAEs. No new safety signals were identified. High clinician- and patient-reported satisfaction were observed following individualized onabotulinumtoxinA treatment, as well as improved global function. Interim results from ASPIRE demonstrate etiology-specific similarities and differences in clinical approaches to manage spasticity. ASPIRE found etiology-specific similarities and differences in real-world onabotulinumtoxinA utilization for spasticity. Across all etiologies, there was high clinician- and patient-reported satisfaction with onabotulinumtoxinA treatment. In DAS, all etiologies showed improved global function in lower limb mobility following onabotulinumtoxinA treatment. Adverse event data varied by etiology of spasticity; however, no new safety signals were identified. ASPIRE data may guide clinical strategies and educational programs to improve onabotulinumtoxinA spasticity management.

The Effect of Repeated abobotulinumtoxinA (Dysport®) Injections on Walking Velocity in Persons with Spastic Hemiparesis Caused by Stroke or Traumatic Brain Injury. PM R 2020; 13:488-495. [PMID: 32741133 PMCID: PMC8246752 DOI: 10.1002/pmrj.12459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 06/29/2020] [Accepted: 07/13/2020] [Indexed: 11/11/2022]
Abstract
Background Botulinum toxin (BoNT) injections were shown to improve muscle tone of limbs in patients with spasticity. However, limited data are available regarding the effects of repeated BoNT injections on walking ability. Objective To assess changes in walking velocity (WV), step length, and cadence under different test conditions after repeated treatment with abobotulinumtoxinA (aboBoNT‐A; Dysport) in spastic lower limb muscles. Design Secondary analysis of an open‐label, multiple‐cycle extension (National Clinical Trials number NCT01251367) to a phase III, double‐blind, randomized, placebo‐controlled, single‐treatment cycle study, in adults with chronic hemiparesis (NCT01249404). Setting Fifty‐two centers across Australia, Belgium, the Czech Republic, France, Hungary, Italy, Poland, Portugal, Russia, Slovakia, and the United States. Patients 352 Ambulatory adults (18‐80 years) with spastic hemiparesis and gait dysfunction caused by stroke or traumatic brain injury, with a comfortable barefoot WV of 0.1 to 0.8 m/s. Interventions Up to four aboBoNT‐A treatment cycles, administered to spastic lower limb muscles. Main Outcome Measurements Changes from baseline in comfortable and maximal barefoot and with shoes WV (m/s), step length (m/step), and cadence (steps/minutes). Results At Week 12 after four injections, WV improved by 0.08 to 0.10 m/s, step length by 0.03 to 0.04 m/step, and cadence by 3.9 to 6.2 steps/minutes depending on test condition (all P < .0001 to .0003 vs baseline). More patients (7% to 17%) became unlimited community ambulators (WV ≥0.8 m/s) across test conditions compared with baseline, with 39% of 151 patients classified as unlimited community ambulators in at least one test condition and 17% in all four test conditions. Conclusions Clinically meaningful and statistically significant improvements in WV, step length, and cadence under all four test conditions were observed in patients with spastic hemiparesis after each aboBoNT‐A treatment cycle.

The ReWalk ReStore™ soft robotic exosuit: a multi-site clinical trial of the safety, reliability, and feasibility of exosuit-augmented post-stroke gait rehabilitation. J Neuroeng Rehabil 2020; 17:80. [PMID: 32552775 PMCID: PMC7301475 DOI: 10.1186/s12984-020-00702-5] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Accepted: 05/21/2020] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Atypical walking in the months and years after stroke constrain community reintegration and reduce mobility, health, and quality of life. The ReWalk ReStore™ is a soft robotic exosuit designed to assist the propulsion and ground clearance subtasks of post-stroke walking by actively assisting paretic ankle plantarflexion and dorsiflexion. Previous proof-of-concept evaluations of the technology demonstrated improved gait mechanics and energetics and faster and farther walking in users with post-stroke hemiparesis. We sought to determine the safety, reliability, and feasibility of using the ReStore™ during post-stroke rehabilitation. METHODS A multi-site clinical trial (NCT03499210) was conducted in preparation for an application to the United States Food and Drug Administration (FDA). The study included 44 users with post-stroke hemiparesis who completed up to 5 days of training with the ReStore™ on the treadmill and over ground. In addition to primary and secondary endpoints of safety and device reliability across all training activities, an exploratory evaluation of the effect of multiple exposures to using the device on users' maximum walking speeds with and without the device was conducted prior to and following the five training visits. RESULTS All 44 study participants completed safety and reliability evaluations. Thirty-six study participants completed all five training days. No device-related falls or serious adverse events were reported. A low rate of device malfunctions was reported by clinician-operators. Regardless of their reliance on ancillary assistive devices, after only 5 days of walking practice with the device, study participants increased both their device-assisted (Δ: 0.10 ± 0.03 m/s) and unassisted (Δ: 0.07 ± 0.03 m/s) maximum walking speeds (P's < 0.05). CONCLUSIONS When used under the direction of a licensed physical therapist, the ReStore™ soft exosuit is safe and reliable for use during post-stroke gait rehabilitation to provide targeted assistance of both paretic ankle plantarflexion and dorsiflexion during treadmill and overground walking. TRIAL REGISTRATION NCT03499210. Prospectively registered on March 28, 2018.

Abstract
COVID-19 pandemic is rapidly spreading all over the world, creating the risk for a healthcare collapse. While acute care and intensive care units are the main pillars of the early response to the disease, rehabilitative medicine should play an important part in allowing COVID-19 survivors to reduce disability and optimize the function of acute hospital setting. The aim of this study was to share the experience and the international perspective of different rehabilitation centers, treating COVID-19 survivors. A group of Physical Medicine and Rehabilitation specialists from eleven different countries in Europe and North America have shared their clinical experience in dealing with COVID-19 survivors and how they have managed the re-organization of rehabilitation services. In our experience the most important sequelae of severe and critical forms of COVID-19 are: 1) respiratory; 2) cognitive, central and peripheral nervous system; 3) deconditioning; 4) critical illness related myopathy and neuropathy; 5) dysphagia; 6) joint stiffness and pain; 7) psychiatric. We analyze all these consequences and propose some practical treatment options, based on current evidence and clinical experience, as well as several suggestions for management of rehabilitation services and patients with suspected or confirmed infection by SARS-CoV-2. COVID-19 survivors have some specific rehabilitation needs. Experience from other centers may help colleagues in organizing their services and providing better care to their patients.

Abstract
Background: Botulinum toxin-A (BoNT-A) injections are first-line treatment for adult spasticity. Prior patient surveys have reported that BoNT-A treatment improves quality of life but that symptoms usually recur before the next injection. We aimed to explore, in-depth, patient perceptions of the impact of spasticity and the waning of BoNT-A therapeutic effects. Methods: An internet-based survey was conducted through Carenity, an online patient community, from May to September 2019 in France, Germany, Italy, UK and USA. Eligible respondents were adult patients with spasticity due to stroke, traumatic brain injury (TBI) or spinal cord injury (SCI) who had ≥2 previous BoNT-A injections. Results: Two hundred and ten respondents (mean 47.2 years) met screening criteria and had their responses analyzed. Overall, 43% of respondents had spasticity due to stroke, 30% due to TBI and 27% due to SCI. The mean [95% CI] injection frequency for spasticity management was 3.6 [3.4-3.7] injections/year. Respondents described the time profile of their response to BoNT-A. The mean reported onset of therapeutic effect was 12.9 [12.1-13.7] days and the mean time to peak effect was 5.0 [4.7-5.4] weeks. Symptom re-emergence between injections was common (83%); the time from injection to symptom re-emergence was 89.4 [86.3-92.4] days. Muscle spasms usually re-emerge first (64%), followed by muscle stiffness or rigidity (40%), and limb pain (20%). Over half (52%) of respondents said they had lost their self-confidence, 46% experienced depression and 41% experienced a lack of sleep due to their spasticity symptoms in the past 12 months. Following a report of symptom re-emergence, the most common management approaches were to add adjunctive treatments (36%), increase the BoNT-A dose (28%), and wait for the next injection (26%). Seventy two percentage of respondents said they would like a longer lasting BoNT-A treatment. Conclusions: Patients with spasticity can expect a characteristic profile of BoNT-A effects, namely time lag to onset and peak effect followed by a gradual decline in the symptomatic benefits. Symptom re-emergence is common and has significant impact on quality of life. Greater patient/clinician awareness of this therapeutic profile should lead to better level of overall satisfaction with treatment, informed therapeutic discussions and treatment schedule planning.

Abstract
OBJECTIVES To evaluate the feasibility of an additional therapeutic upper limb exercise (ULE) intervention in early phase post-stroke rehabilitation and to assess outcomes of therapy using the Armeo Spring (ARMEO) versus Therapist-assisted Table Top (TAT) interventions. DESIGN Randomized, single-blind trial. SETTING Stroke acute inpatient rehabilitation unit. PARTICIPANTS Forty-five participants early after first stroke, Fugl-Meyer Assessment (FMA) score >8, Modified Ashworth score (MAS) of <3. INTERVENTIONS Participants were randomized to TAT or ARMEO ULE in addition to the required 3 hours of 1:1 standard of care provided in an inpatient rehabilitation facility (IRF). MAIN OUTCOME MEASURES Completed number of treatments; withdrawals; serious/adverse events; Functional Independence Measure (FIM) motor; FIM efficiency; FMA; MAS; elbow active (A) and passive (P) range of motion (ROM); and therapist effort measured by the Modified Borg Rating of Perceived Exertion Scale (RPE). RESULTS Post-intervention FIM and FMA scores increased but did not demonstrate any statistically significant differences between the intervention groups (P = .585, .962, partial n2 = .001, .001, respectively). There were no statistically significant differences in post-intervention MAS elbow flexion and extension (P = .332, .252, partial n2 = .009, .007, respectively) and A/P ROM elbow extension between training groups (P = .841, .731, partial n2 = .001, .003, respectively). There was a statistically significant difference in post-intervention A/P ROM elbow flexion between groups (P = .031, .018, partial n2 = .123, .146). Post-intervention RPE did not show any statistically significant differences between the training groups (P = .128, partial n2 = .063). Total elbow range showed larger adjusted mean gains for the ARMEO. No serious adverse events were reported. CONCLUSIONS This study demonstrates that additional therapeutic ULE in the early phase of post-stroke inpatient rehabilitation is feasible and that both interventions showed positive changes in selected outcomes.

Abstract
Objective To examine the safety and efficacy of abobotulinumtoxinA in patients previously treated with botulinum toxin type A (BoNT‐A) products other than abobotulinumtoxinA. Design Secondary analysis from a phase 3, double‐blind, single‐cycle, randomized, placebo‐controlled study. Setting Fifty‐two centers (11 countries). Patients Adults with spastic hemiparesis were randomized (1:1:1) to receive abobotulinumtoxinA 1000 U, 1500 U, or placebo in their affected lower limb. Main Outcome Measurements Muscle tone (6‐point Modified Ashworth Scale [MAS], 0‐5) for the gastrocnemius‐soleus complex (GSC); proportion of MAS responders (≥1‐point improvement); angle of catch (XV3) and spasticity grade (Y) for the GSC and soleus. Assessments were at weeks 1, 4, and 12 post‐injection. Only descriptive statistics are presented. Results Of 388 patients, 84 received previous BoNT‐A treatment (abobotulinumtoxinA 1000 U: N = 30; abobotulinumtoxinA 1500 U: N = 28; placebo: N = 26). At week 4, mean (SD) changes in MAS score in the GSC were − 0.8 (1.1), −0.9 (1.0), and − 0.4 (0.7) for abobotulinumtoxinA 1000 U, 1500 U, and placebo, respectively. Greater MAS responder rates were observed for abobotulinumtoxinA versus placebo at all time points. Mean (SD) changes (week 4) for abobotulinumtoxinA 1000 U, 1500 U, and placebo for XV3 were: GSC, 8° (21), 6° (10) and 1° (7); soleus, 11° (21), 5° (9) and 0° (8), respectively; for Y: GSC, −0.4 (0.7), −0.6 (0.8) and − 0.0 (0.9); soleus, −0.5 (0.7), −0.5 (0.7) and − 0.1 (0.6), respectively. Safety data and adverse events were consistent with the overall known profile of abobotulinumtoxinA. Conclusions Patients previously treated with other BoNT‐As showed improved muscle tone and spasticity at week 4 following abobotulinumtoxinA injection versus placebo. These findings suggest that abobotulinumtoxinA, at the recommended doses, has a good safety and efficacy profile in adults with lower limb spasticity who were previously treated with other BoNT‐A products.

Individualized OnabotulinumtoxinA Treatment for Upper Limb Spasticity Resulted in High Clinician- and Patient-Reported Satisfaction: Long-Term Observational Results from the ASPIRE Study. PM R 2020; 12:1120-1133. [PMID: 31953896 PMCID: PMC7687094 DOI: 10.1002/pmrj.12328] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 11/23/2019] [Indexed: 11/17/2022]
Abstract
Introduction OnabotulinumtoxinA treatment for spasticity is dependent on numerous factors and varies according to selected treatment goals. Objective To examine real‐world onabotulinumtoxinA treatment utilization and effectiveness in patients with upper limb spasticity over 2 years from the Adult Spasticity International Registry (ASPIRE) study. Design Multicenter, prospective, observational registry (NCT01930786). Setting Fifty‐four international clinical sites in North America, Europe, and Asia. Patients Adults (naïve or non‐naïve to botulinum toxins for spasticity) with upper limb focal spasticity related to upper motor neuron syndrome across multiple etiologies. Interventions OnabotulinumtoxinA administered at clinician's discretion. Main Outcome Measures OnabotulinumtoxinA utilization, clinician and patient satisfaction. Results Four hundred eighty‐four patients received ≥1 treatment of onabotulinumtoxinA for upper limb spasticity. Patients were on average 55.1 years old, 50.8% male, predominantly Caucasian (72.3%), and 38.6% were naïve to botulinum toxins. Stroke was the most frequently reported underlying etiology (74.0%). Most patients (81.2%) had moderate to severe spasticity at baseline. The most commonly treated upper limb clinical presentation was clenched fist (79.1% of patients). Across all presentations, onabotulinumtoxinA doses ranged between 5‐600U. Electromyography (EMG) was most often utilized to localize muscles (≥57.0% of treatment sessions). Clinicians (92.9% of treatment sessions) and patients (85.7%) reported being extremely satisfied/satisfied that treatment helped manage spasticity, and clinicians (98.6%) and patients (92.2%) would definitely/probably continue onabotulinumtoxinA treatment. One hundred seventy‐nine patients (37.0%) reported 563 adverse events (AEs); 15 AEs in 14 patients (2.9%) were considered treatment related. Sixty‐nine patients (14.3%) reported 137 serious AEs; 3 serious AEs in 2 patients (0.4%) were considered treatment related. No new safety signals were identified. Conclusions ASPIRE captured the real‐world individualized nature of onabotulinumtoxinA utilization for upper limb spasticity over 2 years, with consistently high clinician‐ and patient‐reported satisfaction. Data in this primary analysis will guide clinical use of onabotulinumtoxinA, as well as provide insights to improve educational programs on spasticity management.

Abstract
Muscle overactivity is a general term for pathological increases in muscle activity such as spasticity. It is caused by damage to the central nervous system at the cortical, subcortical or spinal levels, leading to an upper motor neuron syndrome. In routine clinical practice, muscle overactivity, which induces abnormal muscle tone, is usually evaluated by using the Modified Ashworth Scale or the Tardieu Scale. However, both of these scales involve testing in passive conditions that do not always reflect muscle activity during dynamic tasks such as gait or reaching. To determine appropriate treatment strategies, muscle overactivity should be evaluated by using objective measures in dynamic conditions. Instrumental motion analysis systems that include 3-D motion analysis and electromyography are very useful for this purpose. The method can be used to identify patterns of abnormal muscle activity that can be related to abnormal kinematic patterns. It allows for objective and accurate assessment of the effects of treatments to reduce muscle overactivity on the movement to be improved. The aim of this point-of-view article is to describe the utility of instrumental motion analysis and to outline both its numerous advantages in evaluating muscle overactivity and to present the current limitations for its use (e.g., cost, the need for an engineer, errors relating to marker placement and cross talk between electromyography sensors).

Abstract
Improving walking function is a desirable outcome in rehabilitation and of high importance for social and vocational reintegration for persons with neurologic-related gait impairment. Robots for lower limb gait rehabilitation are designed principally to help automate repetitive labor-intensive training during neurorehabilitation. These include tethered exoskeletons, end-effector devices, untethered exoskeletons, and patient-guided suspension systems. This article reviews the first 3 categories and briefly mentions the fourth. Research is needed to further define the therapeutic applications of these devices. Additional technical improvements are expected regarding device size, controls, and battery life for untethered devices.
