Single chair stand:  Repeated chair stands in 15 seconds (first)

Single chair stand:  Repeated chair stands in 15 seconds (second)

Right hand grip strength: Measurement #1 (kg).

Right hand grip strength: Measurement #2 (kg).

Left hand grip strength: Measurement #1 (kg).

Left hand grip strength: Measurement #2 (kg).

Side-by-side balance test time (seconds).

Tandem stand balance test time #1 (seconds).

Tandem stand balance test time #2 (seconds).

Repeated chair stand: time it took to rise out of a chair 5 times in succession (seconds).

Course measurement method for timed walk.

Flag indicating the Timed Walk tests were performed outside of the protocol. Rather than timing one length of the course (out), and then timing another length (back), the time reported is for the round trip (i.e., out and back).
