Visual Feedback in Chronic Low Back Pain of Pregnant and Nonpregnant Women
- Conditions
- Low Back Pain
- Interventions
- Other: Visual feedbackOther: No visual feedback
- Registration Number
- NCT03493360
- Lead Sponsor
- Aveiro University
- Brief Summary
The objectives of this study are to:
* Evaluate the effect of visual feedback on the intensity of low back pain, range of motion and function of pregnant and non-pregnant women with chronic low back pain.
* Determine the association between low back pain, catastrophizing, fear of movement and low back perception/image.
- Detailed Description
It is antecipated that 15 pregnant women with low back pain and 15 non-pregnant women with low back pain will enter the study. Each group will receive two different interventions, one consisting of visual feedback when performing 10 repetitions of low back flexion, extension and right and left side-flexion and another intervention consisting of the same low back movements without visual feedback. Participants will be assessed for pain intensity, pain location, disability, kinesiophobia, catastrophizing, perception of the low back, flexion range of motion and time to perform the sit to stand test both at baseline and after the intervention.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 24
- The sample will consist of 15 pregnant participants (ideally between the 2nd and 3rd trimester of gestation) with chronic idiopathic low back pain and a group of 15 non-pregnant women with chronic idiopathic low back pain.
- Pregnant women with risk pregnancy will be excluded as well as low back pain with a known cause (e.g. radiculopathy) and all participants with serious pathologies (e.g. history of trauma, surgery for less than 12 months, neurological pathologies, tumors).

Group Intervention Description Visual feedback Visual feedback Participants will be asked to perform movements of the low back while looking at a mirror for visual feedback. No visual feedback No visual feedback Participants will be asked to perform movements of the low back while the mirrors are covered and no visual feedback is provided.
- Primary Outcome Measures
Name Time Method Pain intensity Immediately after the intervention (at 30 minutes) Measured using the visual analogue scale, which measures pain intensity (range: 0-10 and higher values are indicative of higher pain intensity)
- Secondary Outcome Measures
Name Time Method Pain location Immediately after the intervention (at 30 minutes) Measured using a body chart
Disability Immediately after the intervention (at 30 minutes) Assessed using the Roland Morris Questionnaire, which assesses low back pain associated disability (range: 0-24 and higher values indicate higher disability)
Flexion range of motion Immediately after the intervention (at 30 minutes) The distance between the 3rd finger and the floor is measured with a ruler when participants lean forward.
Time taken to sit and stand 5 times Immediately after the intervention (at 30 minutes) Measured using the sit-to-stand test, i.e., the time, in seconds, that a participant takes to sit and stand from a common chair 5 consecutive times.
Catastrophizing Immediately after the intervention (at 30 minutes) Assessed using the Pain Catastrophizing Scale (range 0-52 and higher values are indicative of higher pain catastrophizing)
Low back perception Immediately after the intervention (at 30 minutes) Assessed by asking participants to draw how they perceive their low back to be
