Randomized Controlled Trial Multicenter StudyBotulinum toxin type A in post-stroke lower limb spasticity: a multicenter, double-blind, placebo-controlled trial.
Lower limb spasticity in post-stroke patients can impair ambulation and reduces activities of daily living (ADL) performance of patients. Botulinum toxin type A (BoNTA) has been shown effective for upper limb spasticity. This study assesses the treatment of lower limb spasticity in a large placebo-controlled clinical trial. ⋯ Assessments of gait pattern using the Physician's Rating Scale and speed of gait revealed no significant treatment differences but showed a tendency towards improvement with BoNTA. No marked difference was noted in the frequency of treatment-related adverse events between BoNTA and placebo groups. This was the first large-scale trial to indicate that BoNTA significantly reduced spasticity in lower limb muscles.

Controlled Clinical TrialPregabalin as mono- or add-on therapy for patients with refractory chronic neuropathic pain: a post-marketing prescription-event monitoring study.
This observational study examined the outcome of two different therapeutic strategies in the treatment of chronic neuropathic pain by including pregabalin (PGB) as mono- or add-on therapy in one of two treatment options. Patients with a pain score of > or =4, refractory to usual care for neuropathic pain for at least 6 months, were allocated consecutively to one of two treatment strategies according to the decision of the physician: complete switch to a flexible-dosage, monotherapeutic or add-on therapy with pregabalin (PGB group), or change established doses and combinations of pre-existing mono- or combination therapy without pregabalin (non-PGB group). ⋯ Comparison of the results observed in the two groups shows that patients in the PGB group achieved significantly greater pain reduction. These results demonstrate that PGB administered twice daily is superior to treatment regimes without PGB in reducing pain and pain-related interference in quality of life.

In stroke patients, it has been suggested that communication disorders could result from lexical and syntactic disorders in left hemisphere lesions and from pragmatics problems in right lesions. However, we have little information on patient behaviour in dyadic communication, especially in conversation. Here, we analyzed the various processes participating in communication difficulties at the rehabilitation phase (1-6 months) post-stroke, in order to define the main mechanisms of verbal and non-verbal communication (VC, NVC) disorders and their relationship with aphasic disorders. ⋯ In conclusion, communication disorders were relatively complex and could not be summarised by syntactical and lexical difficulties in left stroke and pragmatic problems in right stroke. The former also showed severe verbal pragmatic difficulties. Frontal stroke also resulted in evident verbal and non-verbal disorders.
