Unravelling the effect of experimental pain on the corticomotor system using transcranial magnetic stimulation and electroencephalography.

Martel, Marylie; Harvey, Marie-Philippe; Houde, Francis; Balg, Frédéric; Goffaux, Philippe; Léonard, Guillaume (2017)

Abstract : The interaction between pain and the motor system is well-known, with past studies showing that pain can alter corticomotor excitability and have deleterious effects on motor learning. The aim of this study was ...

High- and low-frequency transcutaneous electrical nerve stimulation does not reduce experimental pain in elderly individuals

Bergeron-Vézina, Kayla; Corriveau, Hélène; Martel, Marylie; Harvey, Marie-Philippe; Léonard, Guillaume (2015)

Abstract : Despite its widespread clinical use, the efficacy of transcutaneous electrical nerve stimulation (TENS) remains poorly documented in elderly individuals. In this randomized, double-blind crossover study, we ...

Transcutaneous electrical nerve stimulation and placebo analgesia: is the effect the same for young and older individuals?

Daguet, Inès; Bergeron-Vézina, Kayla; Harvey, Marie-Philippe; Martel, Marylie; Léonard, Guillaume (2018)

Abstract: Purpose: Placebo analgesia refers to a perceived reduction in pain intensity following the administration of a simulated or otherwise medically ineffective treatment. Previous studies have shown that many factors ...

Can we quickly and thoroughly assess pain with the PACSLAC-II? : a convergent validity study in long-term care residents suffering from dementia.

Ruest, Mélanie; Bourque, Monique; Laroche, Sarah; Harvey, Marie-Philippe; Martel, Marylie; Bergeron-Vézina, Kayla; Apinis, Catherine; Proulx, Dominique; Hadjistavropoulos, Thomas; Tousignant-Laflamme, Yannick; Léonard, Guillaume (2017)

Abstract : A previous study found that the modified version of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC-II) is a valid tool to assess pain in elderly individuals suffering from ...

Transcranial magnetic stimulation measures in the elderly: reliability, smallest detectable change and the potential influence of lifestyle habits

Houde, Francis; Laroche, Sarah; Thivierge, Véronique; Martel, Marylie; Harvey, Marie-Philippe; Daigle, Frédérique; Olivares-Marchant, Ailin; Beaulieu, Louis-David; Léonard, Guillaume (2018)

Background: Transcranial magnetic stimulation (TMS) is a non-invasive technique that can be used to evaluate cortical function and corticospinal pathway in normal and pathological aging. Yet, the metrologic properties of ...

Can we improve pain and sleep in elderly individuals with transcranial direct current stimulation? : results from a randomized controlled pilot study

Harvey, Marie-Philippe; Lorrain, Dominique; Martel, Marylie; Bergeron-Vézina, Kayla; Houde, Francis; Séguin, Mario; Léonard, Guillaume (2017)

Abstract : Background: The prevalence of chronic pain and sleep disturbances substantially increases with age. Pharmacotherapy remains the primary treatment option for these health issues. However, side effects and drug ...
