Commercially available activity monitors such as the fitbit charge and apple watch show poor validity in patients with gait aids after total knee arthroplasty.

Purpose: The aim of this study is to determine the validity of consumer grade step counter devices during the early recovery period after knee replacement surgery.

Methods: Twenty-three participants wore a Fitbit Charge or Apple Watch Series 4 smart watch and performed a walking test along a 50-metre hallway. There were 9 males and 14 females included in the study with an average age of 68.

A pilot randomized controlled trial of a lay telephone coaching and web-based intervention for postpartum depression and anxiety: The MPOWER study.

Background: Mental health problems are frequent in the postpartum period, but accessible treatment options are lacking. The MPOWER study investigated whether the use of trained lay coaches could increase the uptake and effectiveness of a web-based intervention (WBI) for women with postpartum depression and/or anxiety.

Objectives: First, to compare the feasibility and acceptability of a WBI for women with postpartum depression and anxiety, with and without the addition of telephone coaching calls.
