Problem Definition[edit | edit source]
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 | edit source]
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 | edit source]
Create a device to aid therapists in patient treatment which will:
- Be comfortable and breathable
- Be able to be donned/ doffed in under 30 seconds
- Interface with an Android application via Bluetooth
- Compare data points against an established baseline
Design Work Examples[edit | edit source]
Back Mounted Hardware Case Designs[edit | edit source]
- Designed for initial harness
Wrist Mounted Hardware Case Designs[edit | edit source]
- Bulky & unable to house all necessary components
Harness Designs[edit | edit source]
- Need for multiple size options
- Unable to switch arms
- Difficult to don/dof
Hardware Prototype Version[edit | edit source]
- Contains multiplexer, orientation sensors, and Arduino Feather
Phone App Flow[edit | edit source]
Work Product Examples[edit | edit source]
Upper Arm Mounted Hardware Case[edit | edit source]
- Contains power supply, Arduino Feather, multiplexer, & absolute orientation sensor
- Soft, curved Ninjaflex bottom for comfort and stability
- 4.6x3.5x0.62 inches
Wrist/ Back Mounted Hardware Case[edit | edit source]
- Contains BNO055 absolute orientation sensor
- Compact, minimalistic, and allows easy access
- 1.2x1.5x0.5 inches
Harness[edit | edit source]
- Adjustable Velcro straps
- Back and wrist sensors
- Upper arm sensor
Hardware Final Version[edit | edit source]
Phone App Screenshots[edit | edit source]
- Generates placeholder baseline data which can be compared against placeholder exercise data
Testing and Validation[edit | edit source]
- 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 | edit source]
- 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
