Aim: The purpose of this study was to examine the effectiveness of botulinum toxin A (BoNT-A) therapy combined with rehabilitation on motor function in post-stroke patients. Methods: The following sources up to December 31, 2018, were searched from inception for articles in English: Pubmed, Scopus, CINAHL, Embase, PsycINFO, and CENTRAL. Trials using injections of BoNT-A for upper and lower limb rehabilitation were examined. We excluded studies that were not performed for rehabilitation or were not evaluated for motor function. Results: Twenty-six studies were included. In addition to rehabilitation, nine studies used adjuvant treatment to improve spasticity or improve motor function. In the upper limbs, two of 14 articles indicated that significant improvement in upper limb motor function was observed compared to the control group. In the lower limbs, seven of 14 articles indicated that significant improvement in lower limb motor function was observed compared to the control group. Conclusions: The effect of combined with rehabilitation is limited after stroke, and there is not sufficient evidence, but results suggest that BoNT-A may help to improve motor function. In future studies, the establishment of optimal rehabilitation and evaluation times of BoNT-A treatment will be necessary for improving motor function and spasticity.

Objectives: This study is a retrospective investigation of the effects of repetitive botulinum toxin A therapy (BoNT-A) and intensive rehabilitation (IR) on lower limb spasticity in post-stroke patients. Methods: Thirty-five post-stroke patients was included in this study and received BoNT-A for the first time. A 12-day inpatient protocol was with 4 cycles of the treatment protocol. The severity of spasticity, motor function and brace status were evaluated. Results: The modified Ashworth Scale (MAS) score of ankle dorsiflexors, range of motion, walking speed and balancing ability were significantly improved after cycle 1. The improvement of spasticity and motor function was persistent through cycles 2–4. One-third of brace users were able to discontinue the use of a brace. All of these brace users showed a forward gait pattern prior to therapy. Conclusions: Repeated BoNT-A combined with IR improved lower limb spasticity in post-stroke patients. Our results suggest that patients who show the forward gait pattern prior to therapy may be able to discontinue the use of their brace after therapy.

We aimed to investigate plastic changes in cerebral white matter structures using diffusion tensor imaging following a 15-day stroke rehabilitation program. We compared the detection of cerebral plasticity between generalized fractional anisotropy (GFA), a novel tool for investigating white matter structures, and fractional anisotropy (FA). Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) of 2400 pulses applied to the nonlesional hemisphere and 240 min intensive occupation therapy (OT) daily over 15 days. Motor function was evaluated using the Fugl-Meyer assessment (FMA) and Wolf Motor Function Test (WMFT). Patients underwent diffusion tensor magnetic resonance imaging (MRI) on admission and discharge, from which bilateral FA and GFA values in Brodmann area (BA) 4 and BA6 were calculated. Motor function improved following treatment (p<0.001). Treatment increased GFA values for both the lesioned and nonlesioned BA4 (p<0.05,p<0.001, resp.). Changes in GFA value for BA4 of the lesioned hemisphere were significantly inversely correlated with changes in WMFT scores (R2=0.363,p<0.05). Our findings indicate that the GFA may have a potentially more useful ability than FA to detect changes in white matter structures in areas of fiber intersection for any such future investigations.

Purpose/aim: An intervention that combines low-frequency repetitive transcranial magnetic stimulation and intensive occupational therapy can improve brain function in post-stroke patients with motor paralysis. The purpose of the present study is examined motor function recovery by repetitive transcranial magnetic stimulation and intensive occupational therapy and changes in the activity of motor cortex based on magnetic resonance imaging data. Materials and methods: In total, we assessed 30 patients with post-stroke upper extremity paralysis who were hospitalized for 12 sessions of low-frequency repetitive transcranial magnetic stimulation over the lesion-free hemisphere plus daily occupational therapy for 15 days. Imaging analysis was performed using 3-dimensional T1-weighted image and functional magnetic resonance imaging. Hemispheric dominance was assessed by functional magnetic resonance imaging using the laterality index. In addition, Seed-based functional connectivity analysis was used to evaluate functional connectivity between the precentral gyrus of the affected side and other areas. Results: A positive correlation was found between laterality index before intervention and the Brunnstrom recovery stage for hand/fingers (p < 0.05). The intervention resulted in significantly higher functional connectivity between the precentral gyrus of the affected side and that of the healthy side (false discovery rate corrected p < 0.05). Conclusions: We clarified that the recovery of motor function by intervention with low-frequency repetitive transcranial magnetic stimulation and occupational therapy and the increase of functional connectivity between the precentral gyrus on the affected side and the healthy side are related. These results facilitate prognostic predictions and evidence-based medical care.
