Poststroke spasticity (PSS)-related disability is emerging as a significant health issue for stroke survivors. There is a need for predictors and early identification of PSS in order to minimize ...complications and maladaptation from spasticity. Reviewing the literature on stroke and upper motor neuron syndrome, spasticity, contracture, and increased muscle tone measured with the Modified Ashworth Scale and the Tone Assessment Scale provided data on the dynamic time course of PSS. Prevalence estimates of PSS were highly variable, ranging from 4% to 42.6%, with the prevalence of disabling spasticity ranging from 2% to 13%. Data on phases of the PSS continuum revealed evidence of PSS in 4% to 27% of those in the early time course (1-4 weeks poststroke), 19% to 26.7% of those in the postacute phase (1-3 months poststroke), and 17% to 42.6% of those in the chronic phase (>3 months poststroke). Data also identified key risk factors associated with the development of spasticity, including lower Barthel Index scores, severe degree of paresis, stroke-related pain, and sensory deficits. Although such indices could be regarded as predictors of PSS and thus enable early identification and treatment, the different measures of PSS used in those studies limit the strength of the findings. To optimize evaluation in the different phases of care, the best possible assessment of PSS would make use of a combination of indicators for clinical impairment, motor performance, activity level, quality of life, and patient-reported outcome measures. Applying these recommended measures, as well as increasing our knowledge of the physiologic predictors of PSS, will enable us to perform clinical and epidemiologic studies that will facilitate identification and early, multimodal treatment.
Following a severe acquired brain injury, neuro-orthopaedic disorders are commonplace. While these disorders can impact patients' functional recovery and quality of life, little is known regarding ...the assessment, management and treatment of neuro-orthopaedic disorders in patients with disorders of consciousness (DoC).
To describe neuro-orthopaedic disorders in the context of DoC and provide insights on their management and treatment.
A review of the literature was conducted focusing on neuro-orthopaedic disorders in patients with prolonged DoC.
Few studies have investigated the prevalence of spastic paresis in patients with prolonged DoC, which is extremely high, as well as its correlation with pain. Pilot studies exploring the effects of pharmacological treatments and physical therapy show encouraging results yet have limited efficacy. Other neuro-orthopaedic disorders, such as heterotopic ossification, are still poorly investigated.
The literature of neuro-orthopaedic disorders in patients with prolonged DoC remains scarce, mainly focusing on spastic paresis. We recommend treating neuro-orthopaedic disorders in their early phases to prevent complications such as pain and improve patients' recovery. Additionally, this approach could enhance patients' ability to behaviourally demonstrate signs of consciousness, especially in the context of covert awareness.
Among the estimated 20% to 40% of stroke survivors who develop spasticity, the burden of this condition on patients, caregivers, and society is substantial. Stroke survivors with spasticity may ...experience reductions in their ability to perform activities of daily living and in their health-related quality of life. The occurrence of spasticity in stroke survivors may also result in an increased burden on their caregivers, who exhibit poorer physical and emotional health as compared with the general population. The responsibilities that caregivers have to the stroke survivor--in terms of providing medical care, protecting from falls, and assisting with feeding and hygiene, among other tasks of daily living--must be balanced with their responsibilities to other family members and to themselves. Caregivers of stroke survivors often report a feeling of confinement with little opportunity for relief, and although social support can be helpful, it is frequently limited in its availability. In terms of the socioeconomic burden of spasticity after stroke, recent data point to a 4-fold increase in health care costs associated with stroke survivors with spasticity compared with stroke survivors without spasticity. Thus, it is important to reduce the burden of spasticity after stroke. Consequently, effective spasticity treatment that reduces spasticity and the level of disability experienced by stroke survivors will likely increase their functioning and their health-related quality of life and will also result in a diminished burden on their caregivers.
Spastic elbow deformity in patients with upper motor neuron injuries results from an imbalance of flexor and extensor forces across the ulnohumeral joint. Although not all deformities reflect the ...same underlying imbalances, the elbow most commonly rests in a flexed position. Patients may present with a combination of muscle spasticity, myostatic contracture, and/or joint contracture. A focused history and physical examination are essential for developing individualized surgical plans that account for variations in deformity severity and patient goals. Patients may present with or without volitional control; goals and treatment options differ depending on the degree of control present. Techniques include hyperselective neurectomy, tendon lengthening, muscle origin release, myotomy, tenotomy, periarticular soft tissue release, and skin rearrangement. This article presents a comprehensive review of the surgical approach to the volitional and nonvolitional spastic elbow deformities.Spastic elbow deformity in patients with upper motor neuron injuries results from an imbalance of flexor and extensor forces across the ulnohumeral joint.

Abstract
Background: Spasticity following a stroke occurs in about 30% of patients. The mechanisms underlying this disorder, however, are not well understood.
Method: This review aims to define ...spasticity, describe hypotheses explaining its development after a stroke, give an overview of related neuroimaging studies as well as a description of the most common scales used to quantify the degree of spasticity and finally explore which treatments are currently being used to treat this disorder.
Results: The lack of consensus is highlighted on the basis of spasticity and the associated absence of guidelines for treatment, use of drugs and rehabilitation programmes.
Conclusions: Future studies require controlled protocols to determine the efficiency of pharmacological and non-pharmacological treatments for spasticity. Neuroimaging may help predict the occurrence of spasticity and could provide insight into its neurological basis.
Background
Spasticity may affect stroke survivors by contributing to activity limitations, caregiver burden, pain and reduced quality of life (QoL). Spasticity management guidelines recommend ...multidisciplinary (MD) rehabilitation programmes following botulinum toxin (BoNT) treatment for post‐stroke spasticity. However, the evidence base for the effectiveness of MD rehabilitation is unclear.
Objectives
To assess the effectiveness of MD rehabilitation, following BoNT and other focal intramuscular treatments such as phenol, in improving activity limitations and other outcomes in adults and children with post‐stroke spasticity. To explore what settings, types and intensities of rehabilitation programmes are effective.
Search methods
We searched the Cochrane Stroke Group Trials Register (February 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 12), MEDLINE (1948 to December 2011), EMBASE (1980 to January 2012), CINAHL (1982 to January 2012), AMED (1985 to January 2012), LILACS (1982 to September 2012), PEDro, REHABDATA and OpenGrey (September 2012). In an effort to identify further published, unpublished and ongoing trials we searched trials registries and reference lists, handsearched journals and contacted authors.
Selection criteria
We included randomised controlled trials (RCTs) that compared MD rehabilitation (delivered by two or more disciplines in conjunction with medical input) following BoNT and other focal intramuscular treatments for post‐stroke spasticity with placebo, routinely available local services, or lower levels of intervention; or studies that compared MD rehabilitation in different settings, of different types, or at different levels of intensity. We excluded RCTs that assessed the effectiveness of unidisciplinary therapy (for example physiotherapy only) or a single modality (for example stretching, casting, electrical stimulation or splinting only). The primary outcomes were validated measures of activity level (active and passive function) according to the World Health Organization's International Classification of Functioning, Disability and Health. Secondary outcomes included measures of symptoms, impairments, participation, QoL, impact on caregivers and adverse events.
Data collection and analysis
We independently selected the trials, extracted data, and assessed methodological quality using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Due to the limited number of included studies, with clinical, methodological and statistical heterogeneity, quantitative meta‐analysis was not possible. Therefore, GRADE provided qualitative synthesis of 'best evidence'.
Main results
We included three RCTs involving 91 participants. All three studies scored 'low quality' on the methodological quality assessment, implying high risk of bias. All studies investigated various types and intensities of outpatient rehabilitation programmes following BoNT for upper limb spasticity in adults with chronic stroke. Rehabilitation programmes included: modified constraint‐induced movement therapy (mCIMT) compared with a neurodevelopmental therapy programme; task practice therapy with cyclic functional electrical stimulation (FES) compared with task practice therapy only; and occupational, manual therapy with dynamic elbow extension splinting compared with occupational therapy only. There was 'low quality' evidence for mCIMT improving upper limb motor function and spasticity in chronic stroke survivors with residual voluntary upper limb activity, up to six months, and 'very low quality' evidence for dynamic elbow splinting and occupational therapy reducing elbow range of movement at 14 weeks. Task practice therapy with cyclic FES did not improve upper limb function more than task practice therapy alone, only at 12 weeks. No studies addressed interventions in children and those with lower limb spasticity, or after other focal intramuscular treatments for spasticity.
Authors' conclusions
At best there was 'low level' evidence for the effectiveness of outpatient MD rehabilitation in improving active function and impairments following BoNT for upper limb spasticity in adults with chronic stroke. No trials explored the effect of MD rehabilitation on 'passive function' (caring for the affected limb), caregiver burden, or the individual's priority goals for treatment. The optimal types (modalities, therapy approaches, settings) and intensities of therapy for improving activity (active and passive function) in adults and children with post‐stroke spasticity, in the short and longer term, are unclear. Further research is required to build evidence in this area.
The recovery of upper limb function is of great significance for stroke patients to regain their self-care ability, yet it is still a difficult point in clinical practice of neurological ...rehabilitation. This study aimed to investigate the effect of Maitland joint mobilization technique on the recovery of upper extremity function in patients with spasticity after stroke.
From August to December 2023, 71 patients with upper extremity flexor spasm after stroke were recruited and randomly divided into experimental group (n = 35) and control group (n = 36). The control group was given conventional rehabilitation treatment, while the experimental group was treated with Maitland mobilization technique treatment of upper extremity joints on the basis of the control group. The experiment lasted for 8 weeks. Participants of the 2 groups were observed for Fugl-Meyer motor assessment-upper extremity (FMA-UE), box and block test (BBT) and Brunnstrom stage, modified Ashworth scale (MAS), and functional independence measure (FIM) at pre- and post-8 weeks study.
There was no significant difference in gender distribution, hemiplegic side, diagnosis, past history, age, duration, body mass index, and mini-mental state examination between the 2 groups (P > .05). After 8 weeks of intervention, both groups showed significant improvement in FMA-UE, Brunnstrom stage, BBT, FIM, and MAS of the shoulder (P < .05); however, there was no significant change in MAS of the elbow, wrist, and finger joints (P > .05). The posttreatment values showed a significant improvement in FMA-UE, BBT, and FIM in the experimental group compared to the control group. Comparing the changes in pretreatment and posttreatment, FMA-UE, BBT, and FIM in the experimental group were significantly improved compared with those in the control group (P < .05).
Maitland joint mobilization can improve the motor function of upper extremity and the spasticity of shoulder joint complex in patients with stroke.
In contrast to other diseases that go along with spasticity (e.g. spinal cord injury), spasticity in chronic autoimmune diseases involving the CNS is complicated by the ongoing damage of neuronal ...networks that leads to permanent changes in the clinical picture of spasticity.
Multiple sclerosis (MS) is the most frequent autoimmune disease of the central nervous system (CNS) and spasticity is one of the most disabling symptoms. It occurs in more than 80% MS patients at some point of the disease and is associated with impaired ambulation, pain and the development of contractures.
Besides causing cumulative structural damage, neuroinflammation occurring in MS leads to dynamic changes in motor circuit function and muscle tone that are caused by cytokines, prostaglandins, reactive oxygen species and stress hormones that affect neuronal circuits and thereby spasticity.
The situation is complicated further by the fact that therapeutics used for the immunotherapy of MS may worsen spasticity and drugs used for the symptomatic treatment of spasticity have been shown to have the potential to alter immune cell function and CNS autoimmunity itself. This review summarizes the current knowledge on the immunologic pathways that are involved in the development, maintenance, dynamic changes and pharmacological modulation of spasticity in MS.
Background and purpose
Nabiximols is a therapeutic option for patients with multiple sclerosis (MS) spasticity whose symptoms are poorly controlled by conventional oral first‐line medications. This ...study aimed to assess the relationship between changes in spasticity severity (measured on the 0–10 numeric rating scale NRS) and the presence of associated symptoms in patients treated with nabiximols, and to investigate the presence of the newly described ‘spasticity‐plus syndrome’.
Methods
We analyzed real‐world data from the Italian Medicines Agency e‐Registry on 1138 patients with MS spasticity who began treatment with nabiximols. Evaluation time points were baseline, 4 weeks, and 3, 6, 12 and 18 months after treatment start.
Results
Common symptoms associated with MS spasticity in this cohort were pain (38.4% at baseline), sleep disturbances (32.7%), and spasms/cramps (28.5%). Pain was frequently clustered with sleep disturbances (57.2% of pain cases) and spasms/cramps (43.9%). Approximately one‐third of patients with data at all evaluation time points maintained treatment at 18 months. Nabiximols reduced the baseline mean spasticity 0–10 NRS score by 24.6% at Week 4, and by 33.9% at 18 months in treatment continuers. Nabiximols resolved a range of MS spasticity‐associated symptoms at Week 4, and after 18 months in treatment continuers.
Conclusion
This real‐world analysis supports the concept of a spasticity‐plus syndrome and suggests that nabiximols can favorably impact a range of spasticity‐associated symptoms.
This Agenzia Italiana del Farmaco (Italian Medicines Agency) e‐Registry analysis examined the presence of ‘spasticity‐plus syndrome’ in patients with multiple sclerosis (MS) spasticity treated with nabiximols oromucosal spray (n = 1138). The most common spasticity‐associated symptoms at baseline were pain (38.4%), sleep disturbances (32.7%), and spasms/cramps (28.5%). Spasticity‐associated symptoms were present in fewer patients who were still receiving nabiximols at 18 months and had available symptom data (n = 179). No relevant differences in symptom resolution rates were observed according to MS type, disease duration or gender. Along with relevant and durable improvement in MS spasticity, nabiximols responders can experience resolution of MS spasticity‐associated symptoms.
