Real-life upper limb movement analysis
Real-life upper limb movement analysis
Upper limb amputees, hand graft recipients and healthy controls wore accelerometers on their wrists and just above their elbows for 3 days while going about their daily lives.

I worked as a postdoctoral fellow on this work. My work included all the qualitative and quantitative data analysis, and interpretation of findings.

Findings and Publication
Accelerometry data analysis showed that below-elbow prosthesis users remain more unilateral in their upper limb usage during daily-life despite wearing their prosthesis for 8+ hours daily. Hand transplant recipients showed more bilateral upper limb usage than prosthesis users, but not quite as much as healthy controls. More details are found here.

Visualizing Interlimb reliance for the distal sensors using Archimedean spiral graphs. Archimedean spiral graphs depicting %median reliance on the affected/prosthetic side hand over three days in (a) hand graft group, (b) a representative prosthesis user below-elbow amputee, and (c) a representative healthy control subject. Each 360 degree winding in the spiral graph covers a 24-hour period with the inner-most spiral representing day 1, and the outermost representing day 3. Spokes show time in 24-hour format. Each datapoint represents 1 second. The color scheme turns from green to pink with increasedreliance on the affected limb for the hand graft and amputee groups. The color scheme turns from green to pink with increased reliance on the dominant limb for the healthy controls. Hand graft group showed more reliance on their grafted hand as seen by fewer data points in the shade of green compared to the amputee example. Control subject had the least concentration of green data points, compared to the hand graft subjects and amputee example.
