# Isometric reliability test

#### Year: 1997  Country: Germany   Study Population: N=21 symptom-free and untrained individuals 

Denner A. Muskuläre Profile der Wirbelsäule. Berlin, Heidelberg; Springer; 1997. Chapter 7.4, Ergebnisse Eigener Reliabilitäts- und Validitätsuntersuchungen; p. 163–178.

#### Objective

To investigate the reliability of mobility measurement and isometric strength measurement in David spine devices

#### Methods

Measurements were performed on three different days by an experienced tester. The time interval between each examination day was 72 hours. Tests were performed with David spine devices.

#### Outcome

The isometric strength measurements showed a strong correlation (r=0.94-0.99). Also the correlation in mobility measurements (in those movement direction where it was measured) was strong (r=0.90-0.98).
