Summary

This study evaluates the effects of manual and instrument-assisted cervical manipulation on electromyographic activity and sympathetic nervous system.

Conditions

  • Healthy

Interventions

OTHER

Manual Manipulation

Subject was in supine position, and the therapist applied a manual manipulation with right side bending and left rotation of the neck.

OTHER

Instrument-assisted Manipulation

The instrument-assisted manipulation was applied using a handheld Activator IV Adjusting Instrument. Contacts were made firm enough to prevent slipping of the rubber tip but not so firm as to load the spring, in consistence with customary clinical use of the instrument. The spring was then loaded by means of the instrument's trigger mechanism, and the impulse was delivered in an anterosuperior direction, over the posterolateral aspect of the vertebra on the right lamina-pedicle junction of C3.

OTHER

Placebo

Subject was in supine position, and the therapist placed ths subject's cervical with right side bending and left rotation but no manual manipulation was applied.
