Regeneration of Meissner Corpuscles in Diabetic Mice Following Median Nerve Crush
… qualitative and quantitative changes following a median nerve cryocrush of the left forepaw. Right forepaws were used for non-crush controls. Digits II and III from both forepaws were formalin-fixed, frozen sectioned and silver-impregnated to allow for light microscopic examination of the …

Utilization of Musculoskeletal Sonography in Detecting Physiologic Changes of the Median Nerve in a Working Animal Model
… tunnel syndrome (CTS) is through the use of nerve electrodiagnostic testing (EDX). The diagnosis is characterized by a drop in sensory and motor function within the median nerve. This increase in nerve dysfunction is associated with tissue injury, resulting from repetitive movements of the …

In vitro Investigation of Carpal Tunnel Volume and Morphology Changes with Non-Neutral Wrist Postures
… neuropathy resulting from compression of the median nerve within the carpal tunnel, a fibro-osseous compartment in the palmar aspect of the wrist. Non-neutral wrist postures are a commonly reported risk factor for CTS, due to changes in the geometry of the carpal tunnel leading to median nerve …

Comparison of Magnetic Resonance Imaging & Sonography in an Animal Model in the Acute Stages of Carpal Tunnel Syndrome
… by the compression of an enlarged or inflamed median nerve as it passes through the carpal tunnel and deep to the flexor retinaculum. CTS is one of the most common entrapment syndromes of the upper limbs, with hundreds of thousands of new cases of CTS reported by the Centers for Disease Control …

Carpal tunnel syndrome: influencing factors affecting post surgical recovery rates for functional hand recovery
… year period was analyzed to determine if days of median nerve compression affected post-surgical grip strength recovery rates. In conclusion, less than 10% of the sample recovered 75% or more of normal grip strength after surgery. There was no statistical significance found between post-surgical …

Attention-Deficit/Hyperactivity Disorder (ADHD) and the influence of multisensory processes and sensorimotor integration on motor performance
… The second study, which utilized short-latency median nerve somatosensory evoked potentials (SEPs) paired with a novel visuomotor paradigm, yielded results of differing N18 and N30 SEP peak responses in those with ADHD. This suggests alterations to olivary-cerebellar-M1 processing and SMI when …

Differenzierung zwischen axonaler und demyelinisierender Schädigung bei Patienten mit Multipler Sklerose durch Untersuchung der hochfrequenten SEP-Komponenten nach Medianus-Stimulation
… the primary cortical response (N20) in human median nerve somatosensory evoked potentials (SEPs). HFOs are generated both in deep axon segments of thalamo-cortical projection neurons and at the primary somatosensory cortex. To test the hypothesis that HFOs might be more sensitive to temporal …

Zirkadiane Modulation hochfrequenter SEP-Komponenten (600 Hz) nach Medianusstimulation in Abhängigkeit von tonischer alertness
Human somatosensory evoked potentials (SEP) after median nerve stimulation contain a low-amplitude (< 500 nV) high-frequency (~ 600 Hz) burst of repetitive oscillations superimposed onto the primary cortical response “N20”, which can be obtained by digitally filtering the wide-band SEPs. Previous …

Unterschiedliche Generierung niedrig- und hochfrequenter Komponenten somatosensorisch evozierter Potenziale (SEP) beim Menschen
Human median nerve somatosensory evoked potentials (SEP) contain a low-amplitude (< 500 nV) high-frequency (600 Hz) burst of repetitive wavelets (HFOs) which are superimposed onto the primary cortical response 'N20'. This study aimed to further clarify the cortical and subcortical structures …

Variabilität thalamischer und kortikaler Hochfrequenz (600 Hz) somatosensibel evozierter Potentiale durch Modulation des Aktivierungszustandes bei fokussierter Aufmerksamkeit
… at the scalp after conventional electrical median-nerve stimulation contain a low-amplitude (<500 µV),high-frequency (~600 Hz) burst of repetitive wavelets, which are superimposed onto the primary cortical responseN20. Previous electroencephalographic (EEG) studies have shown: (1) that these …

Genetic risk factors for carpal tunnel syndrome
… which, in turn, causes compression of the median nerve. Although several factors are believed to be associated with increased risk of CTS, the direct causes of this injury remain unknown and it is generally accepted that CTS, with the exception of acutely caused CTS, is a multifactorial …

Multimodal integration of EEG and MEG data using minimum ℓ₂-norm estimates
… Localization accuracy of responses to median-nerve stimulation was evaluated to study the utility of combining MEG and EEG.

Neuromuscular Ultrasound for the Evaluation of Amyotrophic Lateral Sclerosis
… ultrasound could detect changes in peripheral nerves and muscles of individuals with ALS, which could then be used to assist in diagnosis. Several neuromuscular ultrasound parameters were compared between 20 individuals with ALS and 20 age and gender matched controls. The cross-sectional area …

Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis
… less naturalistic stimuli such as electrical median nerve stimulation. The present work contributes new information about the spatiotemporal evolution of the brain’s responses to caress-like touch and highlights the importance of considering both Aβ and CT afferents in gentle touch processing.

Pneumatic ergonomic crutches
… and excessive palmar pressure compressing the median nerve associated with crutch walking have reported to cause discomfort, joint pain, wrist strain, carpal tunnel syndrome and other serious injuries. To address these issues, we developed the pneumatic ergonomic crutches (PEC) that consisted …
