The study found that the new BCI-FEST intervention is safe, feasible, and promising for the rehabilitation of reaching and grasping after SCI. Three out of five participants showed changes greater than the minimal clinically important differences (MCIDs), and four out of five participants achieved MCID in secondary outcome measures.
Study design Feasibility and preliminary clinical efficacy analysis in a single-arm interventional study. Objectives We developed a brain-computer interface-triggered functional electrical stimulation therapy (BCI-FEST) system for clinical application and conducted an interventional study to (1) assess its feasibility and (2) understand its potential clinical efficacy for the rehabilitation of reaching and grasping in individuals with sub-acute spinal cord injury (SCI). Setting Spinal cord injury rehabilitation hospital-Toronto Rehabilitation Institute-Lyndhurst Centre. Methods Five participants with sub-acute SCI completed between 12 and 40 1-hour sessions using BCI-FEST, with up to 5 sessions a week. We assessed feasibility by measuring participants' compliance with treatment, the occurrence of adverse events, BCI sensitivity, and BCI setup duration. Clinical efficacy was assessed using Functional Independence Measure (FIM) and Spinal Cord Independence Measure (SCIM), as primary outcomes. In addition, we used two upper-limb function tests as secondary outcomes. Results On average, participants completed 29.8 sessions with no adverse events. Only one of the 149 sessions was affected by technical challenges. The BCI sensitivity ranged between 69.5 and 80.2%, and the mean BCI setup duration was similar to 11 min. In the primary outcomes, three out of five participants showed changes greater than the minimal clinically important differences (MCIDs). Additionally, the mean change in secondary outcome measures met the threshold for detecting MCID as well; four out of five participants achieved MCID. Conclusions The new BCI-FEST intervention is safe, feasible, and promising for the rehabilitation of reaching and grasping after SCI.
