Bihemispheric repetitive transcranial magnetic stimulation combined with intensive occupational therapy for upper limb hemiparesis after stroke

Abstract

We investigated the safety, feasibility, and efficacy of the combination of bihemispheric repetitive transcranial magnetic stimulation (rTMS) and intensive occupational therapy (OT) for upper limb hemiparesis in poststroke patients. The study participants were eight poststroke patients with upper limb hemiparesis (age at intervention: 62.8±4.9 years, time after stroke: 84.3±87.2 months, mean±SD). During 15 days of hospitalization, each patient received 10 sessions of 40-min bihemispheric rTMS and 240-min intensive OT (120-min one-to-one training and 120-min self-training). One session of bihemispheric rTMS comprised the application of both 1 and 10 Hz rTMS (2000 stimuli for each hemisphere). The Fugl-Meyer Assessment, Wolf Motor Function Test, and the Modified Ashworth Scale were administered on the day of admission and at discharge. All patients completed the treatment without any adverse effects. Motor function of the affected upper limb improved significantly, on the basis of changes in Fugl-Meyer Assessment and Wolf Motor Function Test (P<0.05, each). A significant decrease in the Modified Ashworth Scale score was noted in the elbow, wrist, and finger flexors of the affected upper limb (P<0.05, each). The combination of bihemispheric rTMS and intensive OT was safe and feasible therapy for poststroke hemiparetic patients, and improved motor function of the hemiparetic upper limb in poststroke patients. The findings provide a new avenue for the treatment of patients with poststroke hemiparesis.

Neurodevelopmental outcomes in children with large temporal arachnoid cysts

“…Perhaps in cases in which cognitive function is impaired, consideration should be given to approaches that influence alternative CNS organization via the use of neuromodulation. 19,40…”

“…In addition, VBRS includes screens for mood and anxiety symptoms and a rating of child performance. The parent form 3 has 55 items that comprise 6 subsections: attention (items 1-9), hyperactivity-impulsivity (10)(11)(12)(13)(14)(15)(16)(17)(18), oppositional defiant disorder (19)(20)(21)(22)(23)(24)(25)(26), conduct disorder (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40), and anxiety and depression (41-47). Symptoms are rated using a 0-3 scale where a positive response is a score of 2 or 3 (often and very often, respectively) that reflects problematic behavior.…”

Outcomes in spasticity after repetitive transcranial magnetic and transcranial direct current stimulations

“…Yamada et al (2013) applied low-and high-frequency rTMS simultaneous over both hemispheres (at 1 Hz and 50-second period over the unaffected hemisphere at 10 Hz and 5-second period over affected hemisphere). The authors showed significant improvement in spasticity measured by MAS in the elbow, wrist, and finger flexors in the affected limb (Yamada et al, 2013).…”

Spasticity Management: The Current State of Transcranial Neuromodulation

“…Beyond the choice of the target hemisphere and the underlying pathology, which remain crucial issues [45] and significantly modify the pattern of IHI, intracortical inhibition and facilitation [78] along with the duration of NINM sessions, critically influence the longevity of the after‐effects in a proportional manner [42,45,49,57,60,61]. Moreover, the combination of different NINM paradigms also plays an important role [49,79] in keeping with the principles of priming or of associative plasticity. In addition, the robustness of rTMS is partially invalidated by the discontinuous use of sham‐rTMS controls.…”
