A Study of Neurostyle Brain Exercise Therapy Towards Enhanced Recovery (nBETTER) for Stroke (nBETTER)
A Pilot Feasibility Clinical Trial of Neurostyle Brain Exercise Therapy Towards Enhanced Recovery (nBETTER) for postStroke Arm Paresis
Studieoversigt
Detaljeret beskrivelse
Stroke remains the 4th cause of death in Singapore and despite advances in neuro-medical care and rehabilitation, 40-50% of stroke survivors are left with permanent neuro-disability and a reduced quality of life. The previous 2 decades has seen exponential leaps in the development of rehabilitation technologies which enhance neuroplasticity and rehabilitation outcome. One of these potentially useful technologies is nBETTER System, was developed by Institute for Infocomm Research, Agency for Science, Technology and Research (A*STAR). nBETTER is a portable, internet-connected device that detects the imagination of movement of stroke-affected limb using a Electroencephalography (EEG)-based Brain-Computer Interface (BCI) thus delivering visually engaging feedback for directed neurofeedback aimed at improving upper limb recovery for subacute to chronic stroke patients. The pilot study aims to recruit 13 patients using a multi centre trial design to investigate nBETTER system feasibility and safety for rehabilitation of subacute to chronic stroke patients with upper limb motor impairment and to determine clinical efficacy, safety and feasibility of such a system when it is delivered with standard occupational therapy.
The investigators primary hypothesis is that nBETTER is a feasible and safe prototype in stroke survivors (> 3 months) with moderate to severe arm impairment (FMMA 10-50). The primary outcome is a gain of 15% in Fugl-Meyer motor scores at 6 weeks after 18 sessions (total of 27 hours) of supervised training by occupational therapists and bioengineers.

Beskrivelse
Inclusion Criteria:
- Aged 21-80 years with first-ever clinical stroke diagnosed on CT or MRI brain imaging.
- Stroke duration of 3-24 months.
- Stroke type: ischemic or haemorrhagic
- Fugl-Meyer motor score of the upper limb range from 10-50
- Ability to pay attention and maintain supported sitting for 1.5 hours continuously
- Able to give own consent and understand simple instructions
- Fulfils BCI resting brain states on initial screening.
Exclusion Criteria:
- Recurrent clinical stroke
- Functional status: severe aphasia or inattention, unstable medical conditions which may affect participation (e.g. unresolved sepsis, postural hypotension, end stage renal failure) or anticipated life expectancy of <1 year due to malignancy or neurodegenerative disorder)
- Hemispatial neglect (visual or sensory) or severe visual impairment despite visual aids
- History of epilepsy, severe depression or active psychiatric disorder
- Skull defect or previous cranial surgery as this would affect physical fit of EEG cap interface
- Local arm factors: severe spasticity Modified Ashworth scale >2 in any region, visual analogue scale (VAS score) >4/10, fixed joint contractures or joint replacements, patients with poor skin conditions which would contraindicate repetitive arm training.
- TMS contraindications: females with reproductive potential not on reliable contraception; pregnancy; cardiac pacemakers; orthodontics (braces); metal implants.
