Episode notes
Traumatic Accident And Intensive Recovery
- Jim described being dragged 100 meters under a lorry and having his arm taken off in a traumatic cycling accident.
- He spent six weeks in a coma and endured repeated heart events while doctors fought to save his life.
Prosthetics Expert Becomes A Test Case
- Jim had professional training in prosthetics and orthotics before his accident and used that expertise in his own rehab.
- His peers fitted him with an experimental electronic arm and a titanium osseointegration implant.
Prosthetic Types And Control Tradeoffs
- Jim groups prostheses into task-specific, body-powered, and powered myoelectric devices, each with trade-offs in control and durability.
- The core challenge is restoring rich control channels to match the many degrees of a natural arm.
