Article Synopsis
- Wearable sensors are used to assess gait and balance impairment over long periods, but there's a need to determine the optimal duration for accurate data collection without causing excessive burden on patients.
- Previous studies on sensor wear duration focused on various movement variables but often overlooked important measures like postural sway, highlighting the need for standardized methodologies.
- A new three-level framework was proposed, suggesting that 2 to 3 days of monitoring may suffice for capturing variability, while longer durations could strengthen correlations with patient-reported outcomes, emphasizing the importance of observation frequency and measure variability.
The authors report the use of dense two-dimensional microelectrode array recordings to characterize fine resolution electrocortical activity ("microEEG") in epileptogenic human cortex. A 16-mm(2) 96 microelectrode array with 400-mum interelectrode spacing was implanted in five patients undergoing invasive EEG monitoring for medically refractory epilepsy. High spatial resolution data from the array were analyzed in conjunction with simultaneously acquired data from standard intracranial electrode grids and strips.
