Motor imagery of finger movements: Effects on cortical and muscle activities.

Purpose: The purpose of the current study was to explore the immediate effect of motor imagery (MI) involving finger movement of a given limb on cortical response and muscle activity in healthy subjects.

Methods: Twenty healthy right-handed adults (7 females and 13 males) with a mean + SD age of 22.05 + 6.

Cortical activation and BCI performance during brief tactile imagery: A comparative study with motor imagery.

Brain-computer interfaces (BCIs) rely heavily on motor imagery (MI) for operation, yet tactile imagery (TI) presents a novel approach that may be advantageous in situations where visual feedback is impractical. The current study aimed to compare the cortical activity and digit classification performance induced by TI and MI to assess the viability of TI for use in BCIs. Twelve right-handed participants engaged in trials of TI and MI, focusing on their left and right index digits.

Feasibility and usability of a virtual-reality-based sensorimotor activation apparatus for carpal tunnel syndrome patients.

Purpose: This study aimed to assess the usability of a virtual reality-assisted sensorimotor activation (VRSMA) apparatus for individual digit rehabilitation. The study had two main objectives: Firstly, to collect preliminary data on the expectations and preferences of patients with carpal tunnel syndrome (CTS) regarding virtual reality (VR) and an apparatus-assisted therapy for their affected digits. Secondly, to evaluate the usability of the VRSMA apparatus that was developed.

Evaluation of EEG Oscillatory Patterns and Classification of Compound Limb Tactile Imagery.

: The purpose of this study was to investigate the cortical activity and digit classification performance during tactile imagery (TI) of a vibratory stimulus at the index, middle, and thumb digits within the left hand in healthy individuals. Furthermore, the cortical activities and classification performance of the compound TI were compared with similar compound motor imagery (MI) with the same digits as TI in the same subjects. Twelve healthy right-handed adults with no history of upper limb injury, musculoskeletal condition, or neurological disorder participated in the study.

Large hydrocalyx mimicking as renal cyst and treated by Thulium fiber laser infundibulotomy.

We report a large hydrocalyx with multiple calculi resembling renal cyst with milk of calcium. A 15-year-old female presented with intermittent colicky right flank pain for 10 years with recent increase in pain severity and frequency. Renal ultrasound and CT abdomen revealed right upper pole renal cyst.
