Physiological Factors Of Female Runners With And Without Stress Fracture Histories: A Pilot Study., Therese E Johnston, Colleen Dempsey, Frances Gilman, Ryan Tomlinson, Ann-Katrin Jacketti, Jeremy Close

Department of Physical Therapy Faculty Papers

BACKGROUND: Female runners are at increased risk of stress fractures (SFs) compared with men. Literature is lacking with regard to best practice for preventing and treating SFs in women. The purpose of the study was to compare physiological measures and running-related factors between women of various ages and running abilities with and without a history of running-related SFs.

HYPOTHESIS: Women with and without SF histories will differ with regard to medical and menstrual history, bone health, body composition, nutrition, and running history.

STUDY DESIGN: Prospective cohort study.

LEVEL OF EVIDENCE: Level 2.

METHODS: A total of 20 female runners with …

BACKGROUND. Beige adipose tissue is associated with improved glucose homeostasis in mice. Adipose tissue contains β3-adrenergic receptors (β3-ARs), and this study was intended to determine whether the treatment of obese, insulin-resistant humans with the β3-AR agonist mirabegron, which stimulates beige adipose formation in subcutaneous white adipose tissue (SC WAT), would induce other beneficial changes in fat and muscle and improve metabolic homeostasis.

METHODS. Before and after β3-AR agonist treatment, oral glucose tolerance tests and euglycemic clamps were performed, and histochemical analysis and gene expression profiling were performed on fat and muscle biopsies. PET-CT scans quantified brown adipose tissue volume and …

Reactive Stepping After A Forward Fall In People Living With Incomplete Spinal Cord Injury Or Disease, Katherine Chan, Jae Woung Lee, Janelle Unger, Jaeeun Yoo, Kei Masani, Kristin E Musselman

Physical Therapy Publications

STUDY DESIGN: Cross sectional.

OBJECTIVES: To compare the reactive stepping ability of individuals living with incomplete spinal cord injury or disease (SCI/D) to that of sex- and age-matched able-bodied adults.

SETTING: A tertiary SCI/D rehabilitation center in Canada.

METHODS: Thirty-three individuals (20 with incomplete SCI/D) participated. Participants assumed a forward lean position in standing whilst 8-12% of their body weight was supported by a horizontal cable at waist height affixed to a rigid structure. The cable was released unexpectedly, simulating a forward fall and eliciting one or more reactive steps. Behavioral responses (i.e., single step versus non-single step) were compared …
