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...
The
International 10-20 System is a standardized method for electrode placement in
EEG recordings. The system is based on specific rules for positioning
electrodes on the scalp relative to anatomical landmarks. Here are some key
rules of the International 10-20 System:
1.Measurement
Method: Electrode placement is determined by measuring
distances between specific landmarks on the head. The nasion (bridge of the
nose) and inion (bump at the back of the head) define the sagittal midline,
while the preauricular points (above the ears) define the coronal midline.
2.Incremental
Measurements: Electrodes are positioned at specific
percentages along the sagittal and coronal midlines. The 10-20 System uses 10%
and 20% increments along these lines to determine electrode locations.
3.Letter
Prefix and Number Suffix: Electrode locations are named
using a letter prefix indicating the region of the head (e.g., F for frontal, C
for central) and a number suffix indicating the exact location within the
region. Odd numbers typically represent the left side, even numbers the right
side, and "z" indicates the midline.
4.Consistency
in Naming: The naming convention ensures consistency in
electrode location identification across different EEG recordings and
interpretations. For example, Fp1 represents the left frontal pole, F4 is over
the right frontal lobe, and Cz is at the vertex.
5.10-10
System: A revised version of the 10-20 System, known as
the 10-10 System, addresses inconsistencies in electrode naming, especially for
midtemporal electrodes. It provides a more precise naming scheme for electrode
locations.
6.Standardization
and Accuracy: The 10-20 System promotes standardization in EEG
electrode placement, minimizing variations in electrode positioning across
different individuals and ensuring accurate correspondence between electrodes
and brain structures.
By
following these rules and guidelines of the International 10-20 System, EEG
technicians and clinicians can accurately and consistently place electrodes on
the scalp for EEG recordings, facilitating proper interpretation and analysis
of EEG data.
Electrode Location Names according to
the International 10-20 System
The International
10-20 System is a standardized method for electrode placement in EEG
recordings. Here are the electrode location names according to the
International 10-20 System:
1. Fp1, Fp2: Frontopolar
(Prefrontal)
2. F7, F8: Frontal
3. F3, F4: Frontal
4. C3, C4: Central
5. P3, P4: Parietal
6. O1, O2: Occipital
7. T3, T4: Temporal
8. T5, T6: Temporal
These electrode
locations are crucial for standardizing EEG electrode placement across
individuals and institutions, ensuring consistency in recording and
interpretation of EEG data.
