Abstract
OBJECTIVE This article discusses the effects of myelopathy on multiple organ systems and reviews the treatment and management of some of these effects. LATEST DEVELOPMENTS Recent advances in functional electrical stimulation, epidural spinal cord stimulation, robotics, and surgical techniques such as nerve transfer show promise in improving function in patients with myelopathy. Ongoing research in stem cell therapy and neurotherapeutic drugs may provide further therapeutic avenues in the future. ESSENTIAL POINTS Treatment for symptoms of spinal cord injury should be targeted toward patient goals. If nerve transfer for upper extremity function is considered, the patient should be evaluated at around 6 months from injury to assess for lower motor neuron involvement and possible time limitations of surgery. A patient with injury at or above the T6 level is at risk for autonomic dysreflexia, a life-threatening condition that presents with elevated blood pressure and can lead to emergent hypertensive crisis. Baclofen withdrawal due to baclofen pump failure or programming errors may also be life-threatening. Proper management of symptoms may help avoid complications such as autonomic dysreflexia, renal failure, heterotopic ossification, and fractures.

Abstract
STUDY DESIGN Cross-sectional telephone interviews. OBJECTIVE The coronavirus disease (COVID-19) pandemic placed unprecedented pressure on healthcare systems worldwide. Here, we aimed to investigate the disruptions in management of spasticity and activities of daily living (ADL) in individuals with spinal cord injury (SCI) during the COVID-19 pandemic. SETTING Two university hospitals in Istanbul, Turkey. METHODS Twenty-four individuals with SCI exhibiting moderate and severe spasticity were enroled. All participants underwent ultrasound-guided botulinum toxin type A (BoNT-A) injections at two centres. A self-rated spasticity survey prepared by the authors was conducted. We questioned whether there was an increase in spasticity and the need for new BoNT-A injections during the societal restrictions of the COVID-19 pandemic. Spasticity severity in the previous week was rated using a numeric rating scale (NRS). ADL disrupted by spasticity were assessed by asking open-ended questions. RESULTS In total, 75% participants reported a moderate increase in spasticity, 12.5% reported a severe increase, and 12.5% reported no difference. The mean spasticity NRS score was 6 (standard deviation = 2). Further, 87.5% (21) participants reported the need for BoNT-A treatment because of symptom re-emergence. When spasticity-induced deterioration in ADL was assessed, individuals mostly reported difficulties in walking, sitting on a wheelchair, and sleep disturbance due to spasticity. CONCLUSIONS Most (87.5%) individuals with SCI reported a moderate or severe increase in spasticity during COVID-19 restrictions. Individuals with disabilities are an especially sensitive group and require specialised care during extraordinary circumstances, such as pandemics, hurricanes, or earthquakes. SPONSORSHIP None.

Limb accelerations during sleep are related to measures of strength, sensation, and spasticity among individuals with spinal cord injury. J Neuroeng Rehabil 2022; 19:118. [PMID: 36329467 PMCID: PMC9635075 DOI: 10.1186/s12984-022-01090-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 09/08/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND To evaluate the relationship between measures of neuromuscular impairment and limb accelerations (LA) collected during sleep among individuals with chronic spinal cord injury (SCI) to provide evidence of construct and concurrent validity for LA as a clinically meaningful measure. METHODS The strength (lower extremity motor score), sensation (summed lower limb light touch scores), and spasticity (categorized lower limb Modified Ashworth Scale) were measured from 40 adults with chronic (≥ 1 year) SCI. Demographics, pain, sleep quality, and other covariate or confounding factors were measured using self-report questionnaires. Each participant then wore ActiGraph GT9X Link accelerometers on their ankles and wrist continuously for 1-5 days to measure LA from movements during sleep. Regression models with built-in feature selection were used to determine the most relevant LA features and the association to each measure of impairment. RESULTS LA features were related to measures of impairment with models explaining 69% and 73% of the variance (R²) in strength and sensation, respectively, and correctly classifying 81.6% (F1-score = 0.814) of the participants into spasticity categories. The most commonly selected LA features included measures of power and frequency (frequency domain), movement direction (correlation between axes), consistency between movements (relation to recent movements), and wavelet energy (signal characteristics). Rolling speed (change in angle of inclination) and movement smoothness (median crossings) were uniquely associated with strength. When LA features were included, an increase of 72% and 222% of the variance was explained for strength and sensation scores, respectively, and there was a 34% increase in spasticity classification accuracy compared to models containing only covariate features such as demographics, sleep quality, and pain. CONCLUSION LA features have shown evidence of having construct and concurrent validity, thus demonstrating that LA are a clinically-relevant measure related to lower limb strength, sensation, and spasticity after SCI. LA may be useful as a more detailed measure of impairment for applications such as clinical prediction models for ambulation.

Abstract
INTRODUCTION Post-stroke physical activity has widespread health benefits. Environmental exposures may shape post-stroke physical activity behavior. This study investigates the relationships between environmental exposures and post-stroke physical activity. METHODS Stroke survivors (n=374) from a cohort of Black and White adults with post-stroke accelerometer data (2009-2013) were eligible for this study. Participants' home addresses were linked with secondary data to capture environmental characteristics, including annual density of neighborhood resources (e.g., parks, physical activity facilities, and intellectual stimulation destinations), 2010 neighborhood SES, 2010 neighborhood crime, and daily information on extremely cold days. Post-stroke light physical activity and moderate-to-vigorous physical activity were captured using accelerometers over a 7-day period. Linear regression and 2-part/hurdle models were used to estimate the relationship between the density of neighborhood resources with light physical activity and with moderate-to-vigorous physical activity, respectively. Analyses were conducted in 2021. RESULTS A 10% increase in the number of extremely cold days was associated with 6.37 fewer minutes of daily light physical activity (95% CI= -11.37, -1.37). A 1-SD increase in neighborhood SES was associated with greater odds (OR=1.10, 95% CI=1.02, 1.19) of doing any moderate-to-vigorous physical activity. Among participants obtaining any moderate-to-vigorous physical activity, a 1-unit (count/km2) increase in destinations for intellectual stimulation was associated with 0.99 (95% CI=0.02, 1.97) more minutes of daily moderate-to-vigorous physical activity. All other environmental exposures were not associated with post-stroke light physical activity or moderate-to-vigorous physical activity. CONCLUSIONS Environmental exposures may facilitate physical activity participation among stroke survivors. This study found that weather, neighborhood SES, and proximity to destinations for intellectual stimulation were associated with physical activity over and above individual factors.

Abstract
Spasticity is a common comorbidity of spinal cord injury (SCI) that is characterized by velocity dependent tone and spasms manifested by uninhibited reflex activity of muscles below the level of injury. For some, spasticity can be beneficial and facilitate functional standing, transfers, and some activities of daily living. For others, it may be problematic, painful, and interfere with mobility and function. This manuscript will address the anatomy and physiology of neuromuscular reflexes as well as the pathophysiology that occurs after SCI. Spasticity assessment will be discussed in terms of clinical history and findings on physical examinations, including responses to passive and active movement, deep tendon reflexes, and other long tract signs of upper motor neuron injury, as well as gait and function. Management strategies will be discussed including stretch, modalities, pharmacotherapy, neurolysis, and surgical options.

Intrathecal Baclofen Monotherapy and Polyanalgesia for Treating Chronic Pain in Patients with Severe Spasticity. Curr Pain Headache Rep 2021; 25:79.

Abstract
PURPOSE OF REVIEW Intrathecal drug delivery is a well evidenced strategy for the treatment of many chronic pain syndromes. While opioids, anesthetics, and ziconotide are the most commonly used agents, intrathecal baclofen (ITB), which is indicated to treat spasticity, is also thought to have some analgesic properties that are poorly understood. These analgesic benefits have been reported with ITB use in treating patients with central neurological disorders who suffer from severe spasticity and chronic pain. Our review aims to characterize ITB's effects on pain, function, and quality of life in patients with severe spasticity. We performed a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. The primary outcome parameters were analgesic relief and functional improvements. Secondarily, quality of life and adverse effects were also recorded. RECENT FINDINGS After an initial survey identified 393 studies, 20 studies met final inclusion criteria. Of these, 16 utilized ITB monotherapy and 4 utilized ITB polyanalgesia. Overall, there was a paucity of high-powered studies. Mean titrated ITB doses ranged from 140 to 627.9 μg daily. Nineteen studies reported improved pain and spasticity. Seven studies reported improved functional outcomes and quality of life. Our results show that ITB may be an effective agent in treatingfor the treatment of chronic pain in patients with severe spasticity independent of its spasmolytic effects. Although this evidence was largely derived from studies lacking clearly defined outcomes of pain relief, ITB is reasonable to consider for concurrent spasticity and pain management. Well-designed studies are still needed to characterize ITB's analgesic efficacy when used in patients with severe spasticity.

Abstract
BACKGROUND A number of physiological and atmospheric variables are believed to increase spasticity in persons with spinal cord injury (SCI) based on self-reported measures, however, there is limited objective evidence about the influence of these variables on spasticity. OBJECTIVE We investigated the relationship between physiological/ atmospheric variables and level of spasticity in individuals with SCI. METHODS In 53 participants with motor-incomplete SCI, we assessed the influence of age, time since injury, sex, injury severity, neurological level of injury, ability to walk, antispasmodic medication use, temperature, humidity, and barometric pressure on quadriceps spasticity. Spasticity was assessed using the pendulum test first swing excursion (FSE). To categorize participants based on spasticity severity, we performed cluster analysis. We used multivariate stepwise regression to determine variables associated with spasticity severity level. RESULTS Three spasticity groups were identified based on spasticity severity level: low, moderate, and high. The regression analysis revealed that only walking ability and temperature were significantly related to spasticity severity. CONCLUSIONS These outcomes validate the self-reported perception of people with SCI that low temperatures worsen spasticity. The findings refine prior evidence that people with motor-incomplete SCI have higher levels of spasticity, showing that those with sufficient motor function to walk have the highest levels of spasticity.

Abstract
BACKGROUND Neuroscience and neurotechnology are transforming stroke rehabilitation. Robotic devices, in addition to telerehabilitation, are increasingly being used to train the upper limbs after stroke, and their use at home allows us to extend institutional rehabilitation by increasing and prolonging therapy. The aim of this study is to assess the usability of the MERLIN robotic system based on serious games for upper limb rehabilitation in people with stroke in the home environment. METHODS 9 participants with a stroke in three different stages of recovery (subacute, short-term chronic and long-term chronic) with impaired arm/hand function, were recruited to use the MERLIN system for 3 weeks: 1 week training at the Maimonides Biomedical Research Institute of Cordoba (IMIBIC), and 2 weeks at the patients' homes. To evaluate usability, the System Usability Scale (SUS), Adapted Intrinsic Motivation Inventory (IMI), Quebec User Evaluation of Satisfaction with assistive Technology (QUEST), and the ArmAssist Usability Assessment Questionnaire were used in the post-intervention. Clinical outcomes for upper limb motor function were assessed pre- and post-intervention. RESULTS 9 patients participated in and completed the study. The usability assessment reported a high level of satisfaction: mean SUS score 71.94 % (SD = 16.38), mean QUEST scale 3.81 (SD = 0.38), and mean Adapted IMI score 6.12 (SD = 1.36). The results of the ArmAssist Questionnaire showed an average of 6 out of 7, which indicates that MERLIN is extremely intuitive, easy to learn and easy to use. Regarding clinical assessment, the Fugl-Meyer scores showed moderate improvements from pre- to post-intervention in the total score of motor function (p = 0.002). There were no significant changes in the Modified Ashworth scale outcomes (p = 0.169). CONCLUSIONS This usability study indicates that home-based rehabilitation for upper limbs with the MERLIN system is safe, useful, feasible and motivating. Telerehabilitation constitutes a major step forward in the use of intensive rehabilitation at home. Trial registration ClinicalTrials.gov, NCT04405609. Registered 06 January 2020-Retrospectively registered, https://clinicaltrials.gov/ct2/show/NCT04405609.

Abstract
BACKGROUND The COVID-19 pandemic has affected health-care systems worldwide, including the outpatient spasticity care with botulinum neurotoxin toxin type A (BoNT-A). AIM The aim of this study was to investigate the impact of discontinuation of BoNT-A treatment on patients living with spasticity during the COVID-19 quarantine. DESIGN A multicentric cross-sectional study. SETTING Outpatients setting. POPULATION Patients with spasticity after stroke and traumatic brain injury treated with BoNT-A. METHODS A phone-based survey was conducted from March to May, 2020. Based on the International Classification of Functioning, Disability and Health (ICF), an ad hoc questionnaire CORTOX (CORonavirus TOXin survey) was developed to investigate patients' experiences following the discontinuation of their usual treatment for spasticity due to the lockdown and its implication on their health perception. It assessed patients' condition and explored different ICF domains related to spasticity: unpleasant sensations, mobility, self-care, facilitators and psychosocial factors. The sum of those represented the CORTOX score (Max 142). The questionnaire also collected data about the impact of COVID-19 on patients' wellbeing (mood, sleep, relationships, community life, motivation). RESULTS A total of 151 participants completed the survey. Most participants (72.2%) experienced a worsening in perceived spasticity, 53% got worse in independence and 70.9% had a negative impact on quality of life. The mean CORTOX score was 52.85±27.25, reflecting a perceived worsening in all ICF domains investigated. Moderate to strong correlations were found between different sub-scores of the questionnaire and severity of spasticity (P<0.001). COVID-19 psychosocial related factors were associated with loss of independence (P<0.05) but only mood was associated with worsening of spasticity (P<0.001). The lack of rehabilitation therapy was significantly associated with the worsening of independence but not with the worsening of spasticity. Finally, respondents reported that BoNT-A was useful to their condition and should not be discontinued. CONCLUSIONS The discontinuation of BoNT-A treatment was associated with worsening of activities and participation and perceived spasticity. COVID-19 related problems and rehabilitation showed an association with loss of independence. CLINICAL REHABILITATION IMPACT This study will provide useful information in the field of spasticity management using a patient's centred approach, with consistent quantitative and qualitative information.

Abstract
Aims: To assess children's acceptance to wear a 3D-accelerometer which is attached to the waist under real-world conditions, and also to compare gait speed during supervised testing with the non-supervised gait speed in every-day life. Methods: In a controlled observational, cross sectional study thirty subjects with cerebral palsy (CP), with level I&II of the Gross Motor Function Classification System (GMFCS) and 30 healthy control children (Ctrl), aged 3-12 years, were asked to perform a 1-min-walking test (1 mwt) under laboratory conditions, and to wear an accelerometric device for a 1-week wearing home measurement (1 WHM). Acceptance was measured via wearing time, and by a questionnaire in which subjects rated restrictions in their daily living and wearing comfort. In addition, validity of 3D-accelerometric gait speed was checked through gold standard assessment of gait speed with a mobile perambulator. Results: Wearing time amounted to 10.3 (SD 3.4) hours per day, which was comparable between groups (T = 1.10, P = 0.3). Mode for wearing comfort [CP 1, Range (1,4), Ctrl 1, Range (1,6)] and restriction of daily living [CP 1, Range (1,3), Ctrl 1, Range (1,4)] was comparable between groups. Under laboratory conditions, Ctrl walked faster in the 1 mwt than CP (Ctrl 1.72 ± 0.29 m/s, CP 1.48 ± 0.41 m/s, P = 0.018). Similarly, a statistically significant difference was found when comparing real-world walking speed and laboratory walking speed (CP: 1 mwt 1.48 ± 0.41 m/s, 1 WHM 0.89 ± 0.09 m/s, P = 0.012; Ctrl: 1mwt 1.72 ± 0.29, 1 WHM 0.97 ± 0.06, P < 0.001). Conclusion: 3D-accelerometry is well-enough accepted in a pediatric population of patients with CP and a Ctrl group to allow valid assessments. Assessment outside the laboratory environment yields information about real world activity that was not captured by routine clinical tests. This suggests that assessment of habitual activities by wearable devices reflects the functioning of children in their home environment. This novel information constitutes an important goal for rehabilitation medicine. The study is registered at the German Register of Clinical Trials with the title "Acceptance and Validity of 3D Accelerometric Gait Analysis in Pediatric Patients" (AVAPed; DRKS00011919).

Abstract
CONTEXT Spasticity is one of the most frequent complications in spinal cord injury (SCI), and is routinely managed with oral pharmacologic therapy. Botulinum toxin (BT) is not accepted as a treatment for spasticity in SCI in Spain but may be used in certain cases of focal distribution. OBJECTIVE To report the results with BT for treatment of spasticity in SCI. DESIGN AND SETTING Descriptive retrospective study conducted at a specialist SCI rehabilitation center in Spain, covering patients first treated from 2012 through 2014, and successfully followed up for a minimum of 1 year. Data were collected on the following variables: demographic and SCI characteristics (level and grade); nature of spasticity, e.g. tone, distribution, spasms, articular involvement and pain; function; application of BT; tolerance and adverse reactions. RESULTS The study covered 90 patients, predominantly male with incomplete injuries. Improvement in tone as measured by the modified Ashworth scale was a mean of 1.17 points. Goniometric improvement was achieved in 65.6% and improvement in pain in 38.9% of cases. There were no adverse side-effects. Patients with focal spasticity showed a significantly greater improvement in tone (P < 0.0001). The earlier the BT injection, the greater the improvement in goniometric performance (P < 0.006) and pain (P < 0.033), with the best results being obtained within the first 6 months of clinical course. ASIA D injuries showed a greater improvement in tone (P < 0.0001). CONCLUSIONS BT can be both an effective treatment for focal spasticity in SCI and a good coadjuvant for oral treatments in generalized spasticity.

Abstract
Intrathecal baclofen therapy is a well-established technique for spasticity management. This article briefly reviews the pharmacology of intrathecal baclofen as well as customary approach for utilization of this targeted drug delivery concept. Following these descriptions, four unusual presentations will be described, including the need for initial trialing, patient-directed boluses during chronic intrathecal baclofen therapy, use of medications other than baclofen for intrathecal therapy in spastic patients, and intraventricular baclofen delivery. These hypothetical cases are provided in an effort to expand the use of targeted drug delivery to larger population of spastic patients.

Abstract
Introduction: Differentiating between the components of wrist hyper-resistance post stroke, i.e., pathological neuromuscular activation ("spasticity") and non-neural biomechanical changes, is important for treatment decisions. This study aimed to assess the reliability and construct validity of an innovative measurement device that quantifies these neural and non-neural components by biomechanical modeling. Methods: Forty-six patients with chronic stroke and 30 healthy age-matched subjects were assessed with the NeuroFlexor, a motor-driven device that imposes isokinetic wrist extensions at two controlled velocities (5 and 236°/s). Test-retest reliability was evaluated using intraclass correlation coefficients (ICC) and smallest detectable changes (SDC), and construct validity by testing the difference between patients and healthy subjects and between subgroups of patients stratified by modified Ashworth scale (MAS), and the association with clinical scales. Results: Test-retest reliability was excellent for the neural (NC) and non-neural elastic (EC) components (ICC 0.93 and 0.95, respectively), and good for the viscous component (VC) (ICC 0.84), with SDCs of 10.3, 3.1, and 0.5 N, respectively. NC and EC were significantly higher in patients compared to healthy subjects (p < 0.001). Components gradually increased with MAS category. NC and EC were positively associated with the MAS (r s 0.60 and 0.52, respectively; p < 0.01), and NC with the Tardieu scale (r s 0.36, p < 0.05). NC and EC were negatively associated with the Fugl-Meyer Assessment of the upper extremity and action research arm test (r s ≤ -0.38, p < 0.05). Conclusions: The NeuroFlexor reliably quantifies neural and non-neural components of wrist hyper-resistance in chronic stroke, but is less suitable for clinical evaluation at individual level due to high SDC values. Although construct validity has been demonstrated, further investigation at component level is needed.

Abstract
OBJECTIVE Cervical spinal cord injury (tetraplegia) is known to interrupt sympathetic vasculature control, thereby preventing shunting of blood from the periphery to central organs when exposed to cold temperatures. As a result, persons with tetraplegia are at risk to develop hypothermia. However, information regarding the discomfort experienced during the cooler months (late fall, winter, early spring) is overwhelmingly anecdotal. It is not known, with any certainty, how those with tetraplegia perceive cold and if discomfort in colder environments restricts them from performing activities that they routinely would perform. DESIGN Prospective, two-group, self-report surveys. SETTING VA Medical Center and Kessler Institute for Rehabilitation. PARTICIPANTS Forty-four subjects with tetraplegia; 41 matched non-SCI controls. OUTCOME MEASURES Tetraplegic and control groups responded "yes" or "no" when asked whether cold seasonal temperatures allowed comfort or negatively affected participation in routine activities. RESULTS Percentage of responses of tetraplegia compared to controls was different as to whether they felt cold when others in the same room were comfortable (82 vs. 24%; χ2 = 28.2, P < 0.0001), felt comfortable outdoors (17 vs. 43%; χ2 = 6.8, P = 0.009), or whether cold negatively affected bathing routines (55 vs. 15%; χ2 = 14.8, P = 0.0001), keeping physician appointments (46 vs. 12%; χ2 = 11.3, P = 0.0008), thinking clearly (41 vs. 7%; χ2 = 12.9, P = 0.0003), and completing usual work duties (46 vs. 10%; χ2 = 13.3, P = 0.0003). CONCLUSION Cold seasonal temperatures have a reported greater negative impact on personal comfort and ability to perform vital activities in persons with tetraplegia than that of non-SCI controls. These findings highlight the need to address thermoregulatory impairment in persons with tetraplegia.

Abstract
OBJECTIVE To use an established biomechanical approach to quantify reflex and non-reflex responses from spastic-paretic elbow flexors in response to controlled cold and heat stimulation. METHODS Thirteen spastic-hemiplegic stroke subjects were tested in the experiment. The spastic elbow joint was stretched into extension for 50° at two speeds (5°/s and 100°/s) in a customized apparatus. Thermal stimulation (HEAT at heat pain threshold, COLD at 0°C, or BASELINE at room temperature) was applied to the thenar eminence of the contralateral hand immediately prior to stretching for at least 30 s. RESULTS Total torque was greater at 100°/s than at 5°/s. Total torque was significantly increased after COLD, but not HEAT as compared to BASELINE. When normalized to total torque at baseline, HEAT decreased total torque by 6.3%, while COLD increased total torque by 11.0%. There was no significant difference in the reflex torque among three thermal conditions. CONCLUSION The findings demonstrate differentiated effects of cold stimulation on the total resistance from spastic muscles. They provide objective evidence for anecdotal clinical observations of increased muscle spasticity by cold exposure.

Abstract
OBJECTIVE The adverse events (AEs) with botulinum toxin type-A (BoNTA), used for indications other than spasticity, are widely reported in the literature. However, the site, dose, and frequency of injections are different for spasticity when compared to the treatment for other conditions and hence the AEs may be different as well. The objective of this study was to summarize the AEs reported in Canada and systematically review the AEs with intramuscular botulinum toxin injections to treat focal spasticity. METHODS Data were gathered from Health Canada (2009-2013) and major electronic databases. RESULTS In a 4 year period, 285 AEs were reported. OnabotulinumtoxinA (n=272 events): 68% females, 53% serious, 18% hospitalization, and 8% fatalities. The type of AEs reported were - muscle weakness (19%), oropharyngeal (14%), respiratory (14%), eye related (8%), bowel/bladder related (8%), and infection (5%). IncobotulinumtoxinA (n=13): 38% females, 62% serious, and 54% hospitalization. The type of AEs reported were - muscle weakness (15%), oropharyngeal (15%), respiratory (38%), eye related (23%), bowel/bladder related (15%), and infection (15%). Commonly reported AEs in the literature were muscle weakness, pain, oropharyngeal, bowel/bladder, blood circulation, neurological, gait, and respiratory problems. CONCLUSION While BoNTA is useful in managing spasticity, future studies need to investigate the factors that can minimize AEs. A better understanding of the underlying mechanisms of the AEs can also improve guidelines for BoNTA administration and enhance outcomes.

Abstract
INTRODUCTION Spasticity is one of the most disabling and difficult-to-treat symptoms shown by patients with multiple sclerosis, who often show a suboptimal and unsatisfactory response to classic treatment and new available nonpharmacological alternatives. Due to the progressive nature of this condition, the early management should be essential to improve long-term outcomes. METHODS We performed a narrative literature review of the contribution of spasticity to the burden of multiple sclerosis and the potential role of classic disease-modifying drugs. RESULTS Added to the underlying pathophysiology of spasticity, certain external factors and drugs such as interferon may exacerbate the existing condition, hence their awareness is crucial as part of an effective management of spasticity. Furthermore, the evidence for the effectiveness of glatiramer acetate in preventing spasticity in naïve patients and in those switching from interferon should not be ignored. CONCLUSIONS This literature review proposes the examination of spasticity and the influence of classic disease-modifying agents on the level of existing condition among the variables to be considered when deciding on therapy for multiple sclerosis in clinical practice.

Abstract
Despite the proven efficacy of Sativex(®) (9-delta-tetrahydrocannabinol plus cannabidiol) oromucosal spray in reducing spasticity symptoms in multiple sclerosis (MS), little is known about the neurophysiological correlates of such effects. The aim of the study was to investigate the effects of Sativex on neurophysiological measures of spasticity (H/M ratio) and corticospinal excitability in patients with progressive MS. This was a randomized, double-blind, placebo-controlled, crossover study. Consecutive subjects with progressive MS and lower limb spasticity referred to our center were randomized to 4 weeks' treatment (including 2 weeks' titration) with Sativex or placebo, with crossover after a 2-week washout. Clinical and neurophysiological measures (H/M ratio and cortical excitability) of spasticity were assessed. The H/M ratio was the primary outcome, with sample size calculation of 40 patients. Of 44 recruited patients, 34 were analyzed due to 6 drop-outs and 4 exclusions, which lowered the power of the study to show differences between treatments. Neurophysiological measures did not differ significantly according to treatment and did not correlate significantly with clinical response. Response on the modified Ashworth scale (at least 20 % improvement) was significantly more frequent after Sativex than placebo (50 vs 23.5 %; p = 0.041; McNemar). Side effects did not differ significantly according to treatment. Our findings confirm the clinical benefit of Sativex on MS spasticity. The lack of corresponding changes in corticospinal excitability and on the monosynaptic component, of the stretch reflex, although in a limited sample size, points to the involvement of other spinal and supraspinal mechanisms in the physiopathology of spasticity in progressive MS.

Abstract
PURPOSE To describe the nature, extent, and impact of spasticity; determine factors that are perceived to influence its severity; and examine the relationship between time since diagnosis and impact of spasticity on daily activities in people with stroke and multiple sclerosis (MS) who are receiving botulinum toxin injection treatments. METHODS After a cross-sectional telephone survey, descriptive statistics and correlations were analyzed separately for the stroke and MS groups. RESULTS A total of 29 people with stroke and 10 with MS were surveyed. Both groups perceived increased spasticity with outdoor cold (69% stroke, 60% MS), muscle fatigue (59% stroke, 80% MS), and mental stress (59% stroke, 90% MS). No statistically significant correlations were found between time since diagnosis and perceived impact of spasticity on function in the stroke (r=0.07, p=0.37) or MS (r=0.16, p=0.33) groups. The MS group experienced bilateral and more severe perception of spasticity in the legs than the stroke group and identified more factors as worsening their spasticity (p<0.05). Severity of leg (but not arm) spasticity was significantly correlated with severity of impact of the following factors in the MS group only: lying on the back (r=0.70, p<0.05), outdoor heat (r=0.61, p<0.05), and morning (r=0.59, p<0.05). CONCLUSION Intrinsic and extrinsic triggers can influence the perception of spasticity differently depending on individual factors, severity, location (arm vs. leg), and distribution of spasticity (unilateral vs. bilateral). Clinicians can use the findings to better understand, educate, and treat people with stroke and MS.

Abstract
An operant-conditioning protocol that bases reward on the electromyographic response produced by a specific CNS pathway can change that pathway. For example, in both animals and people, an operant-conditioning protocol can increase or decrease the spinal stretch reflex or its electrical analog, the H-reflex. Reflex change is associated with plasticity in the pathway of the reflex as well as elsewhere in the spinal cord and brain. Because these pathways serve many different behaviors, the plasticity produced by this conditioning can change other behaviors. Thus, in animals or people with partial spinal cord injuries, appropriate reflex conditioning can improve locomotion. Furthermore, in people with spinal cord injuries, appropriate reflex conditioning can trigger widespread beneficial plasticity. This wider plasticity appears to reflect an iterative process through which the multiple behaviors in the individual's repertoire negotiate the properties of the spinal neurons and synapses that they all use. Operant-conditioning protocols are a promising new therapeutic method that could complement other rehabilitation methods and enhance functional recovery. Their successful use requires strict adherence to appropriately designed procedures, as well as close attention to accommodating and engaging the individual subject in the conditioning process.

Abstract
OBJECTIVE To identify and classify tools for assessing the influence of spasticity on quality of life (QOL) after spinal cord injury (SCI). METHODS Electronic databases (MEDLINE/PubMed CINAHL and PsycInfo) were searched for studies published between 1975 and 2012. Dijkers's theoretical framework on QOL was used to classify tools as either objective or subjective measures of QOL. RESULTS Sixteen studies met the inclusion criteria. Identified objective measures that were used to assess the influence of spasticity on QOL included the Short Form-36 (SF-36) the Sickness Impact Profile (SIP) and the Health Utilities Index-III (HUI-III). Subjective measures included the Quality of Life Index-SCI Version III (QLI-SCI) Life Situation Questionnaire-Revised (LSQ-R) Reciprocal Support Scale (RSS) Profile of Mood States (POMS) Spinal Cord Injury Spasticity Evaluation Tool (SCI-SET) and the Patient Reported Impact of Spasticity Measure (PRISM). A number of tools proved either to be insensitive to the presence of spasticity (QLI-SCI) or yielded mixed (SF-36) or weak (RSS LSQ-R) results. Tools that were sensitive to spasticity had limited psychometric data for use in the SCI population (HUI-III SIP POMS) although 2 were developed specifically for assessing spasticity on daily life post SCI (SCI-SET PRISM). CONCLUSIONS Two condition-specific subjective measures the SCI-SET and PRISM emerged as the most promising tools for the assessment of spasticity impact on QOL after SCI. Further research should focus on establishing the psychometric properties of these measures for use in the SCI population.Key words: outcome measurement quality of life spasticity spinal cord injury.
