RESUMO
Background and objectives: Hemispatial neglect is a common consequence of stroke, with an estimated incidence of 23%. Interventions for treating hemispatial neglect may be categorized as either top-down or bottom-up processing. The aim of top-down approaches is to train the person to voluntarily compensate for their neglect. Such approaches require awareness of the disorder and a high level of active participation by the patient. Differently, bottom-up approaches are based on manipulation of a patient's sensory environment and so require less awareness of behavioral bias. In line with the latter, it is conceivable that elastic therapeutic taping applied to the left neck surface may provide bottom-up inputs that reduce hemispatial neglect symptoms. The aim of this study was to assess the effect of therapeutic neck taping on visuo-spatial abilities, neck motion, and kinesthetic sensibility in chronic stroke patients with hemispatial neglect. Materials and Methods: After randomization, 12 chronic stroke patients with hemispatial neglect received 30 consecutive days of real (treatment group) or sham (control group) neck taping. The outcomes were as follows: Stars Cancellation Test; neck active range of motion; Letter Cancellation Test; Comb and Razor Test; Cervical Joint Position Error Test evaluated before and after one month of taping. Results: Between-group comparison showed significant differences only for the Cervical Joint Position Error Test after treatment (p = 0.009). Conclusions: Our preliminary findings support the hypothesis that neck taping might improve cervicocephalic kinesthetic sensibility in chronic stroke patients with hemispatial neglect. Further studies are needed to strengthen our results and better investigate the effects of elastic therapeutic taping on visuo-spatial abilities in stroke patients with hemispatial neglect.

OBJECTIVE: To find more accurate indices that could affect decisions in spasticity treatment by investigating the relation between ultrasonographic, electromyographic, and clinical parameters of the gastrocnemius muscle in adults with spastic equinus after stroke. DESIGN: Observational study. SETTING: University hospitals. PARTICIPANTS: Chronic patients with stroke with spastic equinus (N=43). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Ultrasonographic features were spastic gastrocnemius muscle echo intensity, muscle thickness, and posterior pennation angle of the gastrocnemius medialis (GM) and gastrocnemius lateralis (GL) in both legs. Electromyographic evaluation included compound muscle action potentials (CMAPs) recorded from the GM and GL of both legs. Clinical assessment of the spastic gastrocnemius muscle was performed with the Modified Ashworth Scale (MAS) and by measuring ankle dorsiflexion passive range of motion (PROM). RESULTS: Spastic muscle echo intensity was inversely associated with proximal (GM and GL: P=.002) and distal (GM and GL: P=.001) muscle thickness, pennation angle (GM: P< .001; GL: P=.01), CMAP (GM: P=.014; GL: P=.026), and ankle PROM (GM: P=.038; GL: P=.024). The pennation angle was directly associated with the proximal (GM and GL: P< .001) and distal (GM: P=.001; GL: P< .001) muscle thickness of the spastic gastrocnemius muscle. The MAS score was directly associated with muscle echo intensity (GM: P=.039; GL: P=.027) and inversely related to the pennation angle (GM and GL: P=.001) and proximal (GM: P=.016; GL: P=.009) and distal (GL: P=.006) muscle thickness of the spastic gastrocnemius. CONCLUSIONS: Increased spastic muscle echo intensity was associated with reduced muscle thickness, posterior pennation angle, and CMAP amplitude in the gastrocnemius muscle. Building on previous evidence that these instrumental features are related to botulinum toxin response, these new findings may usefully inform spasticity treatment decisions.

OBJECTIVE: To examine the relationship between patient-rated physician empathy and outcome of botulinum toxin treatment for post-stroke upper limb spasticity. DESIGN: Cohort study. SUBJECTS: Twenty chronic stroke patients with upper limb spasticity. METHODS: All patients received incobotulinumtoxinA injection in at least one muscle for each of the following patterns: flexed elbow, flexed wrist and clenched fist. Each treatment was performed by 1 of 5 physiatrists with equivalent clinical experience. Patient-rated physician empathy was quantified with the Consultation and Relational Empathy Measure immediately after botulinum toxin treatment. Patients were evaluated before and at 4 weeks after botulinum toxin treatment by means of the following outcome measures: Modified Ashworth Scale; Wolf Motor Function Test; Disability Assessment Scale; Goal Attainment Scaling. RESULTS: Ordinal regression analysis showed a significant influence of patient-rated physician empathy (independent variable) on the outcome (dependent variables) of botulinum toxin treatment at 4 weeks after injection, as measured by Goal Attainment Scaling (p<0.001). CONCLUSION: These findings support the hypothesis that patient-rated physician empathy may influence the outcome of botulinum toxin treatment in chronic stroke patients with upper limb spasticity as measured by Goal Attainment Scaling.

Spasticity is common in stroke and multiple sclerosis. To treat spasticity we have a wide range of interventions, whose application may depend not only on the severity of spasticity but also on its etiology. Consequently, a better understanding of muscle spasticity in different neurological diseases may inform clinicians as to the more appropriate therapeutic approach. Our aim was to compare the clinical and ultrasonographic features of spastic equinus in patients with chronic stroke and multiple sclerosis. Thirty-eight patients with secondary progressive multiple sclerosis and 38 chronic stroke patients with spastic equinus were evaluated at the affected ankle according to the following outcomes: modified Ashworth scale, Tardieu scale, passive range of motion, spastic gastrocnemius muscle echo intensity and thickness. Affected calf muscles tone was significantly greater in patients with chronic stroke (modified Ashworth scale P=0.008; Tardieu scale angle P=0.004) as well as spastic gastrocnemius muscle echo intensity (P<0.001). Affected ankle range of motion was significantly greater in patients with multiple sclerosis (P<0.001) as well as spastic gastrocnemius muscle thickness (medialis: P=0.003; lateralis: P=0.004). Our findings evidenced that the same pattern of spasticity (equinus foot) has some different features according to its etiology. This may help the management of spasticity.

Pain is a common and disabling symptom in patients with stroke, multiple sclerosis (MS), cerebral palsy (CP), spinal cord injury (SCI) and other conditions associated with spasticity, but data on its prevalence, and natural history, as well as guidelines on its assessment and treatment in the field of neurorehabilitation, are largely lacking. The Italian Consensus Conference on Pain in Neurorehabilitation (ICCPN) searched and evaluated current evidence on the frequency, evolution, predictors, assessment, and pharmacological and non-pharmacological treatment of pain in patients with stroke, MS, CP, SCI and other conditions associated with spasticity. Patients with stroke, MS, CP, and SCI may suffer from pain related to spasticity, as well as nociceptive and neuropathic pain (NP), whose prevalence, natural history, impact on functional outcome, and predictors are only partially known. Diagnosis and assessment of the different types of pain in these patients is important, because their treatment may differ. Botulinum neurotoxin is the first choice treatment for spasticity, while some antidepressant and antiepileptic drugs may be effective on NP, but pharmacological treatment varies according to the underlying disease. In most cases, a single therapy is not sufficient to treat pain, and a multidisciplinary approach, which include pharmacological and non-pharmacological treatments is needed. Further studies, and in particular randomized controlled trials, are needed on these topics.
