AI Article Synopsis

  • This study is a descriptive, cross-sectional design focused on how breast cancer treatments affect the nervous system and upper extremity sensitivity.
  • It aims to assess elbow extension range of motion (EE-ROM) during neurodynamic testing in women who have undergone breast cancer treatment.
  • Results show that women with pain and lymphedema have the most significant limitations in EE-ROM, especially in the affected limb, with reported symptoms being more intense in the shoulder, arm, and chest areas.

Article Abstract

Study Design: Descriptive, cross-sectional.

Introduction: Breast cancer (BC) treatments place the nervous system at risk, which may contribute to upper extremity (UE) mechanosensitivity.

Purpose Of The Study: To evaluate elbow extension range of motion (EE-ROM) during upper limb neurodynamic testing (ULNT) post-BC treatment.

Methods: ULNT EE-ROM was measured for 145 women post-BC treatment. Women were sub-grouped by presence/absence of pain and lymphedema.

Results: Mean EE-ROM during ULNT1 was -22.3° (SD 11.9°) on the unaffected limb and -25.99° (SD 13.1°) on the affected limb. The women with pain and lymphedema had the greatest limitation in EE-ROM during ULNT1 testing, particularly of their affected limb (-33.8°, SD 12.9). Symptoms were reported more frequently in the affected chest, shoulder, arm, elbow, and hand. The intensity of symptoms was greater at the affected chest (p = 0.046), shoulder (p = 0.033) and arm (p = 0.039).

Conclusions: Women with lymphedema and pain after BC treatment may present with altered neural mechanosensitivity.

Level Of Evidence: 3a.

Purpose: The purpose of this study was to report a timeframe for neurologic recovery of complete radial nerve palsies in patients with humeral shaft fractures treated with internal fixation.

Methods: We retrospectively analyzed the data of patients who underwent surgical treatment of a humeral shaft fracture between 2016 and 2021 at a level I trauma center. Patients with complete sensory and motor radial nerve palsy were identified.

Background: Mutton Bustin' was developed as a safer alternative to rough stock rodeo events such as bull riding to allow kids to participate in the rodeo. Children hold on to the bareback of a running sheep until they fall, competing to see who can ride the longest. While reports of injuries due to other rodeo events are well described in the literature, there are no reports of Mutton Bustin'-associated injuries.

Introduction: Chronic pain can negatively impact a child's quality of life. Pediatric Intensive Interdisciplinary Pain Treatment (IIPT) programs aim to improve overall functioning despite pain through various rehabilitative strategies. It is, however, unclear whether improved function corresponds to self-reported decrease in pain levels.

Diagnosing Huntington's disease on the medical ward.

Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA

An African American man in his early 40s with progressive gait impairment and chronic cognitive impairment initially presented to the emergency department after statements of self-harm and was hospitalised. Examination revealed notable neurological abnormalities including impaired memory recall, oral dyskinesia/choreiform movements, dystonia of the right upper extremity with drift, hyper-reflexia and spastic gait. On further evaluation, including neurology and genetics consultation and workup, a clinical diagnosis of the neurodegenerative disorder Huntington's disease (HD) was made.
