Table 5 : Tests and Measures Validity and Reliability.

Test or Measurement	Validity	Reliability		Clinically Significant Difference
Goniometry15	*	UE: .86	LE: .58	UE: 5°	LE: 6°
Manual Muscle Test16	62.9-72.3%	89-92% within one grade, inter-tester		NA
QDASH13	.55	.91-.96		NA

* According to Gajdosik and Bohannon, if the measurements are being interpreted the way they are meant to be,
as range of motion present around a joint, then goniometry is a valid measurement.
