# Muscle activity in target muscles in different movement directions of the spine

#### 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 analyze the muscle activity of the target muscles compared to other muscles in David spine devices. 

#### Methods

EMG was used to test the isolation of target muscles during maximal isometric contraction. In 110 and 130 devices also muscle activation during submaximal dynamic muscle work (70% of 1 RM) was tested. 

#### Outcome

Fixation in David spine devices seems to effectively activate target muscles and inhibit other muscles.
