Pooled systematic studies that compare treatment stragegies for post-stroke spasticity prove that Botulinum toxin-A (BoNT-A) has superior efficacy and safety and has become the first line management in tandem with physiotherapy. The natural evolution of spasticity show that, not only are neural mechanisms of muscle hypertonus come into play, but that biomechanical forces may likely set in 3 months after stroke. Uses of BoNT-A have been driven by pre-defined goals in the established stage of spasticity (i.E. > 6 months from onset of stroke), as well as the practice of repeat cycle injections to reduce muscle tone. About 19-33% of patients develop spasticity within 3 months after the ictus. Early intervention with BoNT-A (i.e. < 3 months from onser stroke spasticity) can be aimed at preventing the increasing severity of spasticity and the contracture development. There are two randomiaed double blind placebo-controlled trials, and a one single blind comparator trial with a non-injected group, that have recently been performed as early BoNT-A intervention, in tandem with rehabilitation. All the 3 trials showed benefit in terms of reduction in muscle tone with BoNT-A, and one study showed improvement in function, in subanalysis of severely weak muscles at baseline. In the large double blind placebo controlled study, pain reduction was achieved and muscle tone had sustained reduction over the longitudinal observation of 24 weeks, despite a single cycle injection of BoNT-A. The combination of early nrurorehabilitation and early BoNT-A application is an appealing therapeutic approach for upper limb post-stroke spasticity. Neurorehabilitation by constraint-induced movement therapy, in tandem with BoNT-A have been proven to reduce muscle overactivity and improve motor control, but remains to be established in a setting of early spasticity.

Amongst stroke patients, more than a third will develop spasticity, especially those that involve the paretic upper limbs. Despite establish intensive rehabilitaion programs in place, spasticity still affect a post-stroke patient's quality of life and create significant economic and caregiver burdens. The rationale for botulinum toxin type A (BoNT-A) use in spasticity is hinged on the toxin's ability to reduce muscle overactivity via a dual cholinergic blockede of extrafusal and intrafusal muscle. Efficacy and safety of BoNT-A in established post-stroke spasticity have been widely published, effectively establishing robustness of data and first line recommendation. Consensus guidelines and algorithms on the clinical use of BoNT-A for symptomatic upper limb spasticity are now also available. While BoNT-A has been universally shown to reduce muscle tone in spasticity, optimizing therapy requires judicious use of the toxin, while raising one's consciousness of adverse event, including muscle weakness, unwanted or desired in therapy. BoNT-A should not be administered alone in post-stroke spasticity, and its effects are best optimized in concert with a comprehensive neurorehabilitation program.

Targeted for relief of spasms, posturing, pain, impaired function and disfigurement, botulinum toxin type-A (BoNT-A) was injected in dystonias of X-linked dystonia-parkinsonism (XDP). From 1992-2012, focal/ multifocal dystonia combinations were injected in XDP at the following regions: Peri-ocular (21 cases), oromandibular (50 cases), ligual (35 cases), laryngeal (5 cases), cervical (56 cases), truncalaxil (24 cases) upper limbs (13 cases) and lower limbs (18 cases). Pain was frequently reported in 40/50 cases with oromandibular dystonia, 28/56 cases with cervical dystonia, 18/24 cases with truncal-axil dystonia and 16/31 cases with limb dystonia. Outcomes were assessment through the global dystonia rating scale (DRS) at week 4, VAS pain reduction at week 4, duration of BoNT-A effects and safety. Cranial, laryngeal and cervical dystonia showed substantial improvement (DRS median score of 3-4), whereas truncal-axil and limb dystonias showed moderate improvement (DRS median score of 2), following BoNT-A. Pain reduction ranged from 30-100% (VAS), for those dystonias that reported co-morbid pain. BoNT-A effects had a duration ranging from 8-20 weeks. Procedures were generally well tolerated, and the adverse events were most significant in laryngeal injections (voice breathiness, but was eventually followed by a strong voice). The other events were mouth dryness, dysphagia and weekness in oromandibular, cervical and limb dystonias, respectively. Therefore, BoNT-A is a safe and valuable therapeutic option for the dystonias of XDP, especially the disabling and painful dystonias. BoNT-A injection working protocols could be adopted in dystonia that adheres to cost minimization (e.g. lower dose end per selected muscles), yet achieving a substantial benefit, and a reduced adverse event profile. Futhermore, this present study allowed us to recommend a "high potency, low dillution" of BoNT-A in oromandibular, linual, laryngeal, cervical and distal limb dystonias. In dystonias of the abdominal, paraspinal and proximal limb muscles, the "low potency, high dilution" BoNT-A injection protocol could be adopted.

OBJECTIVE: To determine the prevalence of anxiety and its correlation with the quality of life among cognitively-intact, community dwelling Filipino patients with idiopathic Parkinson disease (PD) seen at the Movement Disorders Clinic of a tertiary hospital.
STUDY DESIGN: Prospective, cross-sectional study.
METHODS: Seventy six (76) Filipino outpatients fulfilling the United Kingdom Parkinson Disease Society Brain Bank Clinical Diagnostic Criteria for PD were included in the study. Demographic data were obtained including: age, sex, onset of disease, disease duration and medication intake. The Mini Mental State Examination (MMSE) was done to exclude significant cognitive impairment. The Hamilton Anxiety scale (HAM-A) was administered to quantify anxiety. The degree of anxiety was correlated with the quality of life instrument, Short form health survey (SF 36); and the functional and motor severity using the Unified Parkinson Disease Rating Scales (UPDRS).
FINDINGS: Our cohort of patients had a mean: age of 61 years (range: 42 - 81 years), and disease duration of 1.3 years (33 months). Out of the 76 patients, 37( 48.6%) probably had significant anxiety symptoms based on the the HAM A. Anxiety greatly impacts scores on SF 36.
CONCLUSION: The prevalence of anxiety among this Filipino cohort of patients is 48.6% which is higher than commonly reported worldwide. The presence of anxiety significantly correlated with poorer quality of life.
