A unique aspect of this trial is a telerehabilitation component that aims to give feedback to all participants to practice with the affected arm and walk daily. All participants will be asked to wear bilateral ankle sensors that connect to an Android phone and record lower extremity activity, including walking and cycling. Data includes daily sedentary and active time, walking speed and distance for each bout, and stance:swing ratios for quality of gait. Each participant will be supplied with a kit that includes two accelerometer with gyroscope sensors with Bluetooth and straps for the ankles, two wireless inductive chargers, an Android smartphone with data plan and app for automatic data upload, and instructions with photos. Prior to inpatient discharge, the coordinator at each site will show each study subject and caregiver how to put on and charge the sensors. At their leisure, they can watch a video about how to use the system. The site coordinator will obtain a template of a 10-m walk to train the activity algorithm. At the weekly call, participants will be reminded to try to build up to walking at least 3 times a day for at least 10 minutes per bout and reduce sedentary time. Behavioral modification techniques that the investigators have been using successfully, based on sensor data, will be employed.
