Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
exciteBCI is a wearable rehabilitation device that is novel paired associative stimulation intervention that utilises a brain computer interface (BCI) that aims to promote neural plasticity and improve walking ability in people with stroke. The exciteBCI device augments standard rehabilitation programme. Participants wear an electroencephalography headset and an electrical muscle stimulator over the dorsiflexor or plantar flexor muscles of the ankle, or the quadriceps or hamstring muscles of the thigh depending on the nature of the task and which muscles are prime movers for the task. An application on an ipad controls the device and provides a muscle stimulation timed with the intention to move.
Part one of study: Participants are asked to attend one 90 minute session to explore the usability and acceptability of exciteBCI. Potential users of the exciteBCI will be asked to perform a number of tasks using the exciteBCI whilst engaging in a ‘think-aloud’ process. This involves verbalising their thinking, observations and opinions whilst interacting with the exciteBCI. During the session observational and video recordings are made. The participants also take part in a short semi structured interview after the usability trial. The researcher will ask questions regarding the tasks, design features, pros and cons, and suggested improvements.
Part two of study: Intervention. Following the incorporation of usability feedback two participants with stroke will volunteer to participate in a standard rehabilitation programme augmented by the exciteBCI. The rehabilitation programme will be based on current evidence based practice as recommended in the NZ stroke guidelines and will include task specific training of locomotor skills supervised by a New Zealand registered physiotherapist with clinical experience in stroke rehabilitation. The task specific training will involve an increase in the task complexity over the eight 1-hour sessions over a 3-week period based on principles of motor learning. The rehabilitation workload will be progressed based on the perceived difficulty of each task. The participant will use the exciteBCI throughout the rehabilitation programme. The rehabilitation sessions will be video recorded. Following completion of the rehabilitation programme the person with stroke and the physiotherapist will take part in separate 60-90 minute semi-structured interviews. The rehabilitation programme and interviews will be carried out at AUT University.

Safety
Timepoint [7] 340196 0
Safety monitored by recording any medical/physical changes at the beginning of each session, and any changes during the session. Unrelated events such as illness will be recorded and may result in a session being missed. Possible related events include superficial skin irritation related to electrode placement, or a headache due to wearing the EEG headset. Both of which are considered low risk. Any adverse events requiring the participant to seek medical attention from a health professional will be recorded on an adverse events form.

Part one of study (precedes intervention): Participants are asked to attend one 90 minute session to explore the usability and acceptability of exciteBCI. Potential users of the exciteBCI will be asked to perform a number of tasks using the exciteBCI whilst engaging in a ‘think-aloud’ process. This involves verbalising their thinking, observations and opinions whilst interacting with the exciteBCI. During the session observational and video recordings are made. The participants also take part in a short semi structured interview after the usability trial. The researcher will ask questions regarding the tasks, design features, pros and cons, and suggested improvements.

Statistical methods / analysis
Qualitative descriptive data from the think-aloud protocol and interviews will be analysed using descriptive content analysis. This will provide a rich description of participants’ experiences and opinions of the devices usability and acceptability rather than an interpretation. Data form each of the quantitative measures for the two participants with stroke that participate in the 3-week intervention will be analysed using descriptive statistics.
