Botulinum toxin type-A (Btx-A), a powerful therapeutic tool in various medical specialties, requires repeated injections to maintain its effect. Therefore, novel methods to prolong the effective duration time of Btx-A are highly needed. Rats were assigned to three major groups: control group (n = 30), Btx-A group (n = 30), and IGF-1 Ab groups. IGF-1 Ab groups were composed by sub-groups A1-A5 (...

OBJECTIVE Using ultrasonography (US) to guide botulinum toxin type A (BTX-A) injection in patients with post-stroke wrist and finger flexor muscle spasticity and assessing clinical outcomes after the injection and rehabilitation intervention. METHODS Twenty-three patients with wrist and finger spasticity after stroke were recruited in this study from May 2012 to May 2013. Under US guidance, t...

OBJECTIVE To confirm the apparent effectiveness of botulinum toxin (BTX) in hemiparetic patients with ankle plantar flexors and foot invertor spasticity. METHODS Twenty three hemiparetic patients with spasticity of the ankle plantar flexors and foot invertors were included in a randomised double blind, placebo controlled study with BTX. Patients were examined on days 0, 30, 90, and 120 and re...

Botulinum toxin (BTX) belongs to a family of neurotoxins which strongly influence the function of autonomic neurons supplying the urinary bladder. Accordingly, BTX has been used as an effective drug in experimental therapies of a range of neurogenic bladder disorders. However, there is no detailed information dealing with the influence of BTX on the morphological and chemical properties of nerv...

BACKGROUND Botulinum toxin A (BTX-A) has been successfully used as a treatment for children with spastic cerebral palsy; however, the effect of BTX-A on reducing spasticity only lasts a few months, thus serial injections are required. The present study was to evaluate the efficacy and safety of serial injections of BTX-A in children with spastic cerebral palsy. METHODS Fifty-two pediatric pat...

Hypothesis / aims of study In recent years there has been an increasing use of botulinum toxin-A (BTX-A) for treatment of detrusor overactivity [1]. In contrast, intraprostatic injection of BTX-A has been demonstrated to cause apoptosis in the prostate in humans and in animals [2]. However, the apoptotic action of BTX-A on the detrusor muscle, which could possibly induce atrophy of the bladder,...

BACKGROUND AND AIMS It has not been clarified if botulinum toxin (BTX) injection leads to muscle spindle dysfunction in man. This study aimed to test the hypothesis that BTX application reduces the facilitation of a magnetic evoked response (MEP). METHODS We used the vibration induced facilitation of an MEP of the sternocleidomastoid muscle (SCM) as a surrogate marker for muscle spindle funct...

Botulinum toxin type A (BTX-A), serial casting, and combined treatment for spastic equinus were compared by chart review. Fifty-five patients with diplegia (n=21), hemiplegia (n=17), quadriplegia (n=6), and other diagnoses (n=11) were reviewed. Thirty-one patients had Gross Motor Function Classification System (GMFCS) scores of I or II, 10 had a GMFCS score of III, and eight had GMFCS scores of...

PURPOSE The aim of this study was to determine the force distribution and pattern of mastication after injection of botulinum toxin type A (BTX-A) into both masseter muscles. The hypothesis to be tested was that the difference between right and left balance of occlusal force diminishes over time following BTX-A injection. MATERIALS AND METHODS Fifteen patients were submitted to BTX-A injectio...

The aim of this study was to evaluate the effects of extraocular muscle injection of botulinum toxin-A (BTX-A) on intraocular pressure (IOP) and proptosis in patients with ocular motility disturbances in thyroid associated orbitopathy (TAO). In 17 patients (20 eyes) with restrictive strabismus and diplopia, BTX-A injections were applied. Intraocular pressure was measured with a Goldmann applana...
