Barriers and Opportunities for Using Wearable Devices to Increase Physical Activity Among Veterans: Pilot Study.

Background: Few studies have examined the use of wearable devices among the veteran population.

Objective: The objective of this study was to evaluate veterans' perceptions of and experiences with wearable devices and identify the potential barriers and opportunities to using such devices to increase physical activity levels in this population.

Methods: Veterans able to ambulate with or without assistance completed surveys about their mobile technology use and physical activity levels.

Variations in Influenza Vaccination by Clinic Appointment Time and an Active Choice Intervention in the Electronic Health Record to Increase Influenza Vaccination.

Importance: Influenza vaccination rates in the United States are suboptimal near 40%, but little is known about variations in care based on clinic appointment time.

Objectives: To compare differences in influenza vaccination rates by clinic appointment time and to evaluate the association of an active choice intervention in the electronic health record with changes in vaccination rates.

Design, Setting, And Participants: Retrospective, quality improvement study of 11 primary care practices at the University of Pennsylvania Health System from September 1, 2014, to March 31, 2017.

Greater intracortical inhibition associates with lower quadriceps voluntary activation in individuals with ACL reconstruction.

Decreased voluntary activation contributes to quadriceps weakness following anterior cruciate ligament reconstruction (ACLR). Alterations in neural excitability are likely responsible for reductions in quadriceps voluntary activation, and may be due to specific alterations in intracortical inhibition and facilitation. Therefore, we sought to determine if intracortical inhibition (SICI) and intracortical facilitation (ICF) associate with quadriceps voluntary activation in individuals with ACLR.
