Over the past decade, robotic neurorehabilitation has become one of the most discussed innovations in neurological recovery. Robotic gait trainers, upper-limb rehabilitation systems, exoskeletons, and AI-assisted rehabilitation devices are increasingly being adopted by hospitals and rehabilitation centres worldwide. However, an important question remains: Are robots the future of neurorehabilitation—or are they simply another tool in the rehabilitation toolbox? As clinicians and researchers, we must move beyond marketing claims and focus on scientific evidence, patient selection, and clinical reasoning. What is Robotic Neurorehabilitation? Robotic neurorehabilitation involves the use of electromechanical devices that assist, guide, resist, or augment movement during therapy. These technologies include: • Robotic gait trainers • Wearable exoskeletons • Upper limb robotic rehabilitation devices • End-effector robotic systems • Sensor-based rehabilitation platforms • AI-assiste...
Wicket rhythms can manifest in various forms, each with specific characteristics and patterns.
1. Wicket Fragment:
o Wicket fragments
consist of rhythmic trains of waves that bear similarity to the wicket rhythm
pattern.
o These fragments
typically exhibit a repetitive nature and may resemble segments of the complete
wicket rhythm waveform.
o Distinguishing
wicket fragments from interictal epileptiform discharges (IEDs) is essential,
as they share morphological similarities but are considered normal variants.
2. Wicket Spike:
oWicket spikes are
components of the wicket rhythm characterized by a negative sharp component
followed by a rounded component.
o Morphologically,
wicket spikes resemble diphasic spike and slow wave complexes commonly
associated with epileptiform activity.
o These spikes
often occur over temporal regions, which are frequent sites for interictal
epileptiform discharges.
3. Wicket Wave:
o Wicket waves
exhibit an arciform appearance with alternating sharply contoured and rounded
phases, similar to the overall wicket rhythm pattern.
o The polarity of
wicket waves consists of negative sharp components followed by positive rounded
components, contributing to their distinct waveform.
o These waves are
typically observed in the alpha frequency range and have medium-range
amplitudes compared to other alpha activities.
Recognizing and
understanding the different types of wicket rhythms, including fragments,
spikes, and waves, is crucial for accurate interpretation of EEG recordings. By
identifying these specific patterns and their characteristics, healthcare
professionals can differentiate normal wicket rhythms from abnormal
epileptiform discharges and avoid misdiagnosis or misinterpretation of EEG
findings.
