About this trial

The aim of the study is to investigate test-retest reliability and agreement of trunk muscle activation during functional tasks and clinical sensorimotor control tests in pain-free persons.

Trial outcomes

Primary outcomes

1

Trunk muscle onset during the rapid arm movement test

Trunk muscle onset latencies in response to the unilateral rapid arm movement test will be measured by means of electromyography.

Time frame
Baseline (test-session)
2

Trunk muscle onset during the rapid arm movement test

Trunk muscle onset latencies in response to the unilateral rapid arm movement test will be measured by means of electromyography.

Time frame
After a 30-minute break (retest-session)

Secondary outcomes

1

Trunk muscle (co-)activation

The participant sits on a stool and holds a horizontal bar with both hands, shoulders at 90 degrees (arms are horizontal). The horizontal bar is secured to the ground using a rope and weights. The participant pushes the horizontal bar upwards without moving the arms, pelvis, or spine. The activation of the back and abdominal muscles will be further investigated.

3

Back muscle activation

Back muscle activation will be analyzed during (1) bilateral reaching in standing position, (2) unilateral/bilateral reaching starting in neutral sitting position, and (3) unilateral/bilateral reaching starting in habitual sitting position.
