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.
