Fear-Avoidance Beliefs Questionnaire (FABQ): Kinesiophobia and Graded In Vivo Exposure
In short
Fear of movement feeds the vicious cycle of chronic musculoskeletal disability; identifying elevated FABQ scores directs targeted in vivo exposure to extinguish movement terror.

The Fear-Avoidance Model and Kinesiophobia in Chronic Disability
Vlaeyen and Linton's Fear-Avoidance Model provides the cornerstone paradigm for understanding how acute musculoskeletal pain transitions into chronic disabling pathology. When acute tissue injury occurs, individuals interpret their pain through one of two pathways: low threat leads to active confrontation and recovery, whereas catastrophic misinterpretation generates fear of pain (kinesiophobia).
This fear prompts hypervigilance and widespread avoidance behaviors. Patients stop bending, lifting, working, and walking, presuming that pain equates to structural harm. Over time, prolonged disuse causes muscular atrophy, joint stiffness, neuroplastic cortical reorganization, and psychological depression, paradoxically intensifying pain sensitivity. The Fear-Avoidance Beliefs Questionnaire (FABQ) measures this psychological barrier across two distinct life domains: physical activity (FABQ-PA) and work (FABQ-W).
FABQ Scoring Matrix and Prognostic Cut-Off Thresholds
| FABQ Subscale | Scoring Method & Item Allocation | High-Risk Prognostic Cut-Off | Rehabilitation & Occupational Directive | |
|---|---|---|---|---|
| FABQ - Physical Activity (FABQ-PA) | Items 2, 3, 4, 5 scored 0 to 6; total score range 0 to 24 points | Score > 14 / 24 points | RE-ENGAGE GENERAL MOVEMENT: Focus on walking, light functional agility, and debunking 'fragile spine' myths | |
| FABQ - Work (FABQ-W) | Items 6, 7, 9, 10, 11, 12, 15 scored 0 to 6; total score range 0 to 42 points | Score > 29 / 42 points | HIGH RISK OF WORK DISABILITY: Implement workplace ergonomic adaptations and behavioral return-to-work pacing | |
| Tampa Scale for Kinesiophobia (TSK) | 17-item scale assessing fear of reinjury from movement; score range 17 to 68 | Score > 37 / 68 points | INDICATES BEHAVIORAL EXPOSURE: Standard active exercise therapy alone is insufficient; in vivo exposure mandatory |
Standardized Clinical Rehabilitation Protocols and Graded In Vivo Exposure
- Behavioral Graded In Vivo Exposure Therapy: Use the Photograph Series of Daily Activities (PHODA) to rank feared physical postures (forward bending, vacuuming, overhead lifting); guide the patient to perform the exact feared movement in a safe clinical environment without bracing or guarding, proving that the movement does not cause catastrophe.
- Extinction of Safety Behaviors and Postural Guarding: Identify and actively extinguish maladaptive protective habits, such as gripping countertops when standing up, wearing a lumbar corset 24 hours a day, or holding the breath during bending; relaxed, fluid movement patterns retrain spinal motor units.
- Time-Contingent Rather Than Pain-Contingent Progression: Prescribe exercises based strictly on time or repetition quotas rather than pain intensity; completing predetermined sets teaches the nervous system that movement can be safely accomplished even in the presence of familiar baseline symptoms.
Frequently Asked Questions
If bending my back hurts, isn't it common sense to stop bending?
In the first 48 hours of an acute strain, resting makes sense. However, after the first few days, avoiding bending actually weakens your back muscles, stiffens your spinal ligaments, and trains your brain to treat bending like a dangerous threat. Safe, gradual bending restores spinal nutrition and cures the fear.
How does graded exposure work in real-life physiotherapy?
If you are terrified of picking things off the floor, we do not start by asking you to lift a heavy weight. We begin by having you reach for a high tabletop, then a knee-high chair, then tapping the floor with your fingertips, and finally lifting light objects with relaxed breathing, step by step until your brain realizes bending is safe.
Should I wear a back brace or lumbar belt while doing exercises?
Generally, no. Relying on a rigid back brace becomes a 'safety behavior' that tricks your brain into believing your spine is unstable and fragile. We want your natural core and spinal muscles to support you so you regain genuine confidence in your body.
