Functional recovery from chronic writer’s cramp by brain-computer interface rehabilitation: a case report

Abstract

BackgroundDystonia is often currently treated with botulinum toxin injections to spastic muscles, or deep brain stimulation to the basal ganglia. In addition to these pharmacological or neurosurgical measures, a new noninvasive treatment concept, functional modulation using a brain-computer interface, was tested for feasibility. We recorded electroencephalograms (EEGs) over the bilateral sensorimotor cortex from a patient suffering from chronic writer’s cramp. The patient was asked to suppress an exaggerated beta frequency component in the EEG during hand extension.ResultsThe patient completed biweekly one-hour training for 5 months without any adverse effects. Significant decrease of the beta frequency component during handwriting was confirmed, and was associated with clear functional improvement.ConclusionThe current pilot study suggests that a brain-computer Interface can give explicit feedback of ongoing cortical excitability to patients with dystonia and allow them to suppress exaggerated neural activity, resulting in functional recovery.

Brain–machine interfaces for rehabilitation of poststroke hemiplegia

“…Recently, BMI motor rehabilitation was extended from stroke to other motor disorders, such as spinal cord injuries (Takahashi et al, 2012) or writer's cramp (Hashimoto et al, 2014). While these examples demonstrate improvements in the motor domain, other domains, eg, those responsible for cognition and emotion regulation, might also be targeted by BMI neurorehabilitation paradigms.…”

Systematic Review of Rehabilitation in Focal Dystonias: Classification and Recommendations

“…Active approaches for normalization of muscle activity utilized primarily active participation by the patient. Active approaches included biofeedback through various methods such as visual, auditory, electromyography (EMG), or electroencephalography (EEG) readings . Alternatively, passive methods were considered those in which the primary component of the intervention was the introduction of an externally applied stimulus with little or no emphasis on patient participation.…”

“…For example, studies in Category 1 tested interventions based on intensive movement training to promote improved motor control of affected muscles, such as the use of task‐specific training in musician's dystonia . In contrast, studies in Category 4 focused on improving motor performance by using external techniques such as biofeedback to facilitate the normalization of muscle activity . Therefore, albeit similar, the key component of each category is distinct (i.e., movement practice vs. use of biofeedback).…”

Dampak Frekuensi Pernapasan Predialisis Terhadap Kram Otot Intradialisis Di Rsud Panembahan Senopati Bantul

“…Kondisi ini tentunya dirasakan sebagai sesuatu hal yang sangat mengganggu oleh pasien. Oleh sebab itu, kondisi ini perlu mendapatkan perhatian khusus sejak dari awal pasien datang atau akan me-mulai proses hemodialisis (predialisis), selain penimbangan berat badan yang sudah rutin dilakukan sebelum pasien menjalani hemodialisis (Angraini & Putri, 2016;Katzberg, et al, 2015;Hashimoto, et al, 2014). Perawat juga perlu mengetahui bagaimana status pernapasan pasien sebelum hemodialisis dimulai, dan apa hasilnya dapat menjadi penyebab terjadi kram otot selama hemodialisa (Angraini & Putri, 2016;S.A.M., Rustina & Syahreni, 2013).…”
