The Median Nerve Displays Adaptive Characteristics When Exposed to Repeated Pinch Grip Efforts of Varying Rates of Force Development: An Ultrasonic Investigation.
J Ultrasound Med
December 2024
School of Physical and Health Education, Nipissing University, North Bay, Ontario, Canada.
Objectives: Repeated gripping with high grip forces and high rates of grip force development are risk factors for carpal tunnel syndrome. As the nerve's adaptive ability is crucial to prevent disease progression, we investigated how these risk factors influence median nerve deformation and displacement over the time course of a repeated pinch grip task.
Methods: Seventeen healthy participants performed a repeated grip task against a load cell while their carpal tunnel was scanned with ultrasound.

Department of Orthopaedics, University of Pittsburgh Medical Center, Suite 1010, Kaufmann Building, 3471 Fifth Avenue, Pittsburgh, PA, 15213, USA.
Background: Carpal tunnel syndrome (CTS) is responsible for over 90 % of median nerve neuropathies. Though a clinical diagnosis, evaluation of nerve conduction via electrodiagnostic studies (EDX) and median nerve cross sectional area (CSA) through sonographic imaging provides supporting evidence and insight into disease severity. The advent of handheld ultrasound devices offers a portable, cost-effective and non-invasive method for median nerve assessment, yet its accuracy compared to traditional cart-based ultrasound has not been assessed in this setting.

Wild-type transthyretin cardiac amyloidosis and aortic stenosis: Can carpal tunnel syndrome help distinguish the chicken from the egg?
J Intern Med
November 2024
Referral Center for Cardiac Amyloidosis, Mondor Amyloidosis Network, GRC Amyloid Research Institute and Cardiology Department, APHP Henri Mondor Hospital, Créteil, France.
Article Synopsis
- - The study investigates the relationship between transthyretin wild-type cardiac amyloidosis (TTRwt-CA) and aortic stenosis (AS), proposing a bidirectional connection where each condition may influence the other and lead to systemic manifestations, including carpal tunnel syndrome (CTS).
- - In a sample of 411 TTRwt-CA patients, approximately 70% had CTS, which correlated with younger age, more severe cardiac remodeling, and a higher frequency of extracardiac symptoms, while AS occurred in 21% of those with CTS and 31% without.
- - The research indicates that CTS may differentiate two phenotypes of TTRwt-CA: one associated with systemic involvement and poorly calcified low-flow

Multiparametric Ultrasound Assessment of Carpal Tunnel Syndrome: Beyond Nerve Cross-sectional Area.
Semin Musculoskelet Radiol
December 2024
Clinical Institute of Radiology, University Medical Centre Ljubljana, Ljubljana, Slovenia.
Carpal tunnel syndrome (CTS), the most common mononeuropathy, results from compression of the median nerve within the fibro-osseous carpal tunnel. Diagnosis is typically based on clinical evaluation and confirmed by nerve conduction studies. However, ultrasound (US) has emerged as a valuable noninvasive adjunct for CTS confirmation, offering potential advantages over electrodiagnostic testing in terms of patient comfort and diagnostic accuracy.

Compression neuropathy, such as carpal tunnel syndrome (CTS), results in changed afferent nerve signaling, which may result in changes in somatosensory brain areas. The purpose of this study was to assess cerebral changes following unilateral CTS and to assess short-term and long-term cerebral effects of guided plasticity treatment using ipsilateral cutaneous forearm deafferentation. Twenty-four patients with mild-to-moderate unilateral CTS were randomized to treatment with anesthetic cream (EMLA) or placebo.

BACKGROUND Carpal tunnel syndrome (CTS) is a neuropathy caused by the entrapment of the median nerve, which requires effective management strategies. The median nerve is subjected to pressure within the carpal tunnel, resulting in tingling, numbness, and pain in the median side of the hand. We compared the efficacy of splint use with an exercise program vs exercise alone in patients with mild and moderate CTS.

Division of Cardiovascular Medicine, Department of Internal Medicine, Kobe University Graduate School of Medicine, Hyogo, Japan.
Article Synopsis
- - The study focuses on the increasing detection of wild-type transthyretin (ATTR) amyloidosis and evaluates the effectiveness of Tc-labeled pyrophosphate (Tc-PYP) scintigraphy for diagnosing ATTR cardiac amyloidosis in patients across Japan from 2018 to 2022.
- - Out of 180 patients, 135 were analyzed, with 62 testing positive for Tc-PYP; researchers developed a scoring system based on five clinical factors to predict positivity, revealing that a higher score correlates with a greater likelihood of positive results.
- - The study concludes that combining commonly available clinical data can significantly enhance the pretest prediction accuracy for Tc-PYP scintigraphy, aiding clinicians in the early diagnosis of ATTR amyloidosis

Department of Orthopedics and Trauma, Peking University People's Hospital, Peking University, Beijing, China.
Article Synopsis
- Ultrasound-guided transverse carpal ligament (TCL) needle release is an effective treatment for mild to moderate carpal tunnel syndrome (CTS), but the best approach between long-axis and short-axis techniques has not been previously studied.
- In a randomized controlled trial involving 64 patients, those received either long-axis or short-axis TCL needle release combined with corticosteroid injection, with measures taken before treatment and at multiple follow-up points over 12 months.
- Results showed both groups improved in symptom severity and functional scale scores, but the long-axis approach resulted in significantly better outcomes compared to the short-axis method across all follow-up times.

Division of Cardiology, Severance Hospital, Cardiovascular Research Institute, Yonsei University College of Medicine, 50-1, Yonsei-Ro, Seodaemun-gu, Seoul, 03722, Korea.
Article Synopsis
- The study highlights that transthyretin amyloidosis cardiomyopathy (ATTR-CM) is often overlooked in patients with heart failure and an LVEF greater than 40%.
- Out of 97 studied patients, 13.4% were diagnosed with ATTR-CM, primarily affecting older males, indicating a notable prevalence in this demographic.
- Key features in ATTR-CM patients included higher rates of polyneuropathy and carpal tunnel syndrome, along with specific heart-related metrics like thicker heart walls and prolonged PR interval, suggesting clinicians should consider ATTR when male patients show these symptoms.

Article Synopsis
- The study investigates the relationship between two-point discrimination (2PD) values and the severity of carpal tunnel syndrome (CTS) in patients who have experienced distal radius fractures, using standard methods like electromyography and ultrasonography for severity assessment.
- Results showed a moderate correlation between 2PD values and CTS severity categories, particularly with distal sensory latency and conduction velocity, although the overall correlation was weak.
- The findings suggest that a 2PD cut-off value of 9.5 mm effectively differentiates between severe and non-severe CTS, indicating its potential usefulness in clinical assessments.

Department of Ultrasound, Affiliated Hospital of Nantong University, Nantong University, Jiangsu 226001, PR China.
Article Synopsis
- Carpal Tunnel Syndrome (CTS) is a common nerve disorder requiring accurate diagnosis, and this study proposes a new grading method using ultrasound by measuring the median nerve's cross-sectional area (CSA) and shear wave elastography (SWE) in different wrist positions.* -
- The research involved patients diagnosed with CTS and healthy controls, with significant differences found in median nerve measurements between these groups, particularly highlighting SWE's effectiveness in identifying CTS severity, especially at a 45° wrist flexion.* -
- The findings suggest that using SWE is more reliable than CSA for diagnosing CTS severity, which could lead to better treatment plans and less reliance on invasive methods like nerve conduction studies.*
