Problem Definition[edit]

Individuals recovering from post-stroke arm impairments spend significantly more time conducting therapeutic exercise at home without therapist supervision than they spend doing supervised therapy in a clinical setting. It is difficult to quantify the amount and quality of arm usage that takes place between supervised therapy sessions, which would be useful to know both as an indicator of functional recovery, and also as a way to monitor activity level and its impact on motor recovery.

Motivation[edit]

As the leading cause of serious, long term disability, strokes affect about 795,000 people in the United States annually.[1] Many times, this leads to loss of mobility in one of the patient’s arms.

Objective[edit]

Create a device to aid therapists in patient treatment which will:

  1. Be comfortable and breathable
  2. Be able to be donned/ doffed in under 30 seconds
  3. Interface with an Android application via Bluetooth
  4. Compare data points against an established baseline

Design Work Examples[edit]

ProjectARM-App-3.jpg
  • Generates placeholder baseline data which can be compared against placeholder exercise data

Testing and Validation[edit]

  • Cases & Hardware
    • Protect sensors and components
    • Stable on the wearer
    • Wires between sensors were successfully tested for continuity
    • Sensors and hardware came online when powered up
  • Harness
    • Final design is both comfortable and breathable
    • With help, it is able to be donned/ doffed in under 30 seconds
  • Application
    • Interfaces with the sensors in hardware via Bluetooth
    • Displays a graph of placeholder data points against generated baseline data

Future Goals and Direction[edit]

  • To allow patients to be able to don/ doff with one arm
  • To increase the sensor's stability and accuracy of readings
  • To complete a user-friendly application to follow progress of prescribed exercise routines
  • To integrate a physical On/ Off switch into the hardware
