Bias and sensitivity (mean and standard deviation) of PIP and DIP ‘joint’ angles, and proximal phalanx and mid phalanx segment lengths, during motion capture of wand using static and representative-speed 3-axis translations and rotations.

		PIP	DIP
Joint F–E angle Mean (S.D.) (°)	Static	− 0.02 (0.10)	− 0.31 (0.20)
	Translations	− 0.23 (0.31)	0.32 (0.46)
	Rotations	− 0.11 (0.31)	0.15 (0.47)

		Proximal phalanx	Middle phalanx
Segment length Mean (S.D.) (mm)	Static	60.12 (0.03)	37.21 (0.03)
	Translations	59.87 (0.13)	37.33 (0.08)
	Rotations	59.89 (0.11)	37.24 (0.09)
