Study Overview
Brief Summary
Thigh muscles flexibility deficits contribute to handicap in chronic low back pain patients. The study aims to evaluate the immediate effect of thigh muscles stretching in patients with chronic low back pain. The investigation team suppose that flexibility improvement could be detected by instrumented clinical measurements and such difference could be related to psycho-social factors evaluated by questionnaires.
Detailed Description
The primary objective of the study is to evaluate the immediate effect of the hamstring muscle stretching in patients presenting chronic low back pain. The secondary objectives are: (1) to evaluate intra- and interrater reliability, construct validity and responsiveness of the hamstring flexibility measurements (Active Knee Extension [AKE], Straight Leg Rise [SLR]) realised with digital inclinometer, (2) to evaluate factors that potentially could influence immediate effect of the hamstring stretching, specifically psycho-social factors Fear Avoidance Belief Questionnaire (FABQ), Hospital Anxiety and Depression scale (HAD), neuropathic pain presence (DN4).

Arms & Interventions
hamstring stretching
Participants' lower limb will be positioned in maximal hip flexion and gradually moved to maximal knee extension by physical therapist. The procedure will take one minute for each lower limb.
Intervention: manual hamstring stretching (Other)
Outcomes
Primary Outcomes
Active Knee Extension test (AKE)
Time Frame: Day 1
Description: Participant positioned in supine lying will actively extend his knee while keeping his hip joint in 90 degrees of flexion. Hip position will be verified by digital inclinometer and maintained with a barre indicating vertical position of the participants' thigh. The range of motion will be recorded with digital inclinometer positioned on the tibial craft of the exanimated limb.
Secondary Outcomes
- Straight Leg Rise test (SLR)(Day 1 before stretching, Day 1 after stretching)
- Anxiety and Depression scale(Day 1)
- Fingertip-to-floor distance (FTF)(Day 1 before stretching, Day 1 after stretching)
- Fear Avoidance Belief Questionnaire (FABQ)(Day 1)
- Ostwestry Disability Index(Day 1)
- Neuropathic pain presence(Day 1)
