Figure 1.
Participants sat in a semi-seated, upright posture with the pelvis fixated by a belt. The load was released from one side of the trunk by release of an electromagnet.
Figure 2.
Correlation between TSK and trunk stiffness in response to (a) forward, and (b) backward perturbations.
Figure 3.
Trunk stiffness for forward perturbation for individuals with high and low kinesiophobia (TSK) and fear avoidance beliefs (FABQ).
TSK = Tampa Scale for Kinesiophobia, FABQ-W = Fear Avoidance Beliefs Questionnaire-Work subscale.
