fNIRS Neurofeedback for Post-stroke Hand Rehabilitation

Официальное название

Hand Rehabilitation in People With Hemiparesis After a Stroke Using 3D Imaging With fNIRS Neurofeedback

Обзор

Cardiovascular diseases are one of the main causes of disability. Among post-stroke individuals, 80% experience upper limb dysfunction, while only 5% to 20% of individuals regain full limb and hand function. The purpose of this study is to evaluate the effects of hand rehabilitation of post-stroke individuals using HEG Neurofeedback The study will include 30 participants in the early sub-acute phase post-stroke, who will be assigned to either the study group or the control group. Participants in the experimental group will follow a rehabilitation program extended with HEG Neurofeedback training, while participants in the control group will follow the standard rehabilitation program. The HEG Neurofeedback therapy equipment will be supplemented with new hand therapy software. During the exercises, patients will focus on a discussed and presented task, and once the expected level of concentration is reached, the software will trigger a virtual hand performing a finger flexion movement. Motor control of the hand will be assessed using the Fugl-Meyer Scale and Brunnström recovery stages.

Подробное описание

This study is a prospective, randomized, single-blind clinical trial with intervention. Participants will be recruited from among patients treated at the Rehabilitation Clinic. Inclusion criteria: individuals with hemiparesis after a first ischemic stroke, subacute stroke period (no longer than 3 months), upper limb paresis rated 2-4 by Brunnstrom recovery stages, participants aged 18 to 70 years, consent to participate in the study. Exclusion criteria: unstable general condition, visual field disorders, inability to sit independently, cognitive impairment (Mini-Mental State Examination, MMSE \> 24). The minimum size of the sample was calculated taking into account the number of individuals after stroke hospitalized annually in the re habilitation ward, i.e. approximately 120 patients, of which those in the acute phase of recovery constitute about 40%. It was assumed that 80% of the patients would have a minimum 2 in Brunnstrom scale. A fraction size of 0.8 was used, with a maximum error of 5%, a sample size of 30 patients was obtained.

The allocation of interventions will be determined based on a simple randomization sequence generated using Microsoft Excel. The study coordinator will register participants, generate the random allocation sequence, and assign and schedule participants for the interventions.

Fifteen participants will be assigned to the experimental group and fifteen to the control group.

Interwention. The experimental group will be provided with rehabilitation at the Rehabilitation Clinic and additional exercises with Biofeedback HEG. HEG therapy will be conducted for 15 days, every day from Monday to Friday. The duration of one session is 30 minutes. Participants from the control group will be provided with rehabilitation at the Rehabilitation Clinic and an additional 30 minutes of individual physiotherapy focused on restoring hand function.

Participants will be assessed twice, before the start of the therapy series and immediately after its completion. Motor control of the hand will be assessed using the Fugl-Meyer Scale and Brunnström recovery stages.
