Background: A key motor skill is the ability to rapidly interact with our dynamic environment. Humans can generate goal-directed motor actions in response to sensory stimulus within ~ 60-200ms. This ability can be impaired after stroke, but most clinical tools lack any measures of rapid feedback processing.

Background: Maintaining adequate nutrition is critical for people with amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND). Enteral tube feeding is offered to people experiencing difficulty swallowing (dysphagia) to prevent weight loss and aspiration pneumonia. Among the types of enteral tube feeding, percutaneous endoscopic gastrostomy (PEG) is the typical procedure offered to people with ALS and will be mainly discussed here.

Background: Cognitive and motor function must work together quickly and seamlessly to allow us to interact with a complex world, but their integration is difficult to assess directly. Interactive technology provides opportunities to assess motor actions requiring cognitive control.

Objective: To adapt a reverse reaching task to an interactive robotic platform to quantify impairments in cognitive-motor integration following stroke.

Objectives: The COVID-19 pandemic has led to the widespread uptake of virtual care in Canada; however, virtual care may also create new barriers to health care. The purpose of this paper was to explore patient perceptions and concerns around virtual care access.

Methods: Between February and April 2020, we conducted semi-structured interviews with participants from four chronic disease clinics (stroke, epilepsy, amyotrophic lateral sclerosis, obstetrics medicine) in a mid-sized academic hospital in Southern Ontario, Canada.

Loss of upper extremity function following spinal cord injury (SCI) can have devastating consequences on quality of life. Peripheral nerve transfer surgery aims to restore motor control of upper extremities following cervical SCI and is poised to revolutionize surgical management in this population. The surgery involves dividing an expendable donor nerve above the level of the spinal lesion and coapting it to a recipient nerve arising from the lesional or infralesional segment of the injured cord.

Article Synopsis
  • A study was conducted to assess genetic testing practices at ALS clinics across Canada, using surveys and interviews with clinicians from 27 clinics.
  • Results showed that 93% of clinics regularly test for familial ALS, but only 33% do so for sporadic ALS, highlighting significant barriers such as treatment impact perception, approval challenges, and inadequate genetic counseling access.
  • Findings indicate that genetic testing access varies widely, with an average wait time of 10 months to see a genetic counselor, and calls for improved testing practices to ensure equitable healthcare delivery for ALS patients.

Objective: The purpose of this study was to evaluate Canadian amyotrophic lateral sclerosis (ALS) centres with respect to: 1) the prevalence of Non-invasive positive pressure ventilation (NIPPV) and invasive mechanical ventilation via tracheostomy (TV) utilization, 2) the approach to NIPPV use, focusing upon the currently employed initiation criteria and 3) the barriers influencing NIPPV administration.

Methods: A descriptive survey research design aimed to obtain quantitative data and open-ended responses from an active physician at each of the 15 multidisciplinary Canadian ALS centres.

Results: The principal findings of this study were: 1) NIPPV and TV are used in 18.
