Adolescent Idiopathic Scoliosis and Body Schema

May 21, 2026 updated by: Nuray Alaca, Acibadem University

Investigation of Body Schema as Sensorimotor Representation in Adolescent Idiopathic Scoliosis and Comparison With Healthy Individuals-A Case Control Study

Adolescent idiopathic scoliosis is the most common form of scoliosis. Although an increasing number of studies suggest that an abnormal sensory-motor integration critically contributes to the cause of adolescent idiopathic scoliosis , there is uncertainty about the level of the central nervous system explaining this dysfunction. Therefore, the planned master's thesis study aims to compare proprioception, tactile acuity, right-left reasoning ability, motor imagery ability, including the evaluation of body schema, which is a sensorimotor representation in adolescent idiopathic scoliosis patients with healthy individuals. In addition, the relationship of these markers with posture results, body perception and quality of life of individuals with adolescent idiopathic scoliosis will be investigated as a secondary aim.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The two-point discrimination test
Time Frame: Baseline
The two-point discrimination test is used to assess if the patient is able to identify two close points on a small area of skin, and how fine the ability to discriminate this are. It is a measure of tactile agnosia, or the inability to recognize these two points despite intact cutaneous sensation and proprioception
Baseline
Left/right discrimination (Lateralization)
Time Frame: Baseline
Right-Left Discrimination will be evaluated with Recognise™ applications (Back) developed by the "Neuro Orthopedic Institute".
Baseline
Kinesthetic and Visual Imagery Questionnaire
Time Frame: Baseline
Motor imagery ability will be assessed with the Kinesthetic and Visual Imagery Questionnaire (KVIQ). The participant gives a score between 1 and 5 for the image he/she imagines: "1 point: no image, 5 points: as clear as the original." This process is repeated for each task and at the end of the survey, kinesthetic imagery score, visual imagery score and total score are calculated.
Baseline
Lumbar proprioception test
Time Frame: Baseline
In both groups, thoracic and lumbar repositioning accuracy will be measured and evaluated using the dual inclinometer system.
Baseline
Pressure Pain Threshold
Time Frame: Baseline
A digital pressure algometer will be applied to the web space of the foot opposite the trigger point. Participants are instructed to say "stop" or "pain" so the stimulus can be terminated "when the sensation first transitions from pressure to pain" (pain threshold).
Baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
4D DIERS FORMETIC
Time Frame: baseline
In this study, the newly developed 4D DIERS FORMETIC movable spine and surface topography evaluation device will be used. This device is equipped with a digital network camera that allows measurements at a maximum frequency of up to 50 frames per second. The camera uses CMOS sensors with a resolution of 1280x1024 pixels. Thanks to these sensors and reflective markers, measurements are reconstructed in 3D. Thus, it allows real-time evaluation of posture parameters. Evaluation is done without radiation and without contact.
baseline
Body Image Disturbance Questionnaire--Scoliosis Version
Time Frame: Baseline
It is a seven-item instrument that measures body image disturbance. It assesses (1) concern about body part(s) felt to be unattractive; (2) preoccupation with the concern(s); (3) experiences of emotional distress about appearance; (4) impairment in social, occupational, or other areas of functioning; (5) interference with social life, school, job, or role functioning; (6) avoidance of activities because of appearance; and (7) behavioral avoidance10,26. Using a rating scale from 1 to 5 (with 1 = not at all concerned, and 5 = extremely concerned) to measure each of these items and a mean score for the seven items, the BIDQ allows for continuous, quantitative measurement. Higher scores reflect more severe body image disturbance
Baseline
Walter Reed Visual Assessment Scale
Time Frame: Baseline
It is a scale that scores the severity of curvature by focusing on the person's perception of posture. It is divided into 7 parameters including body curvature, rib prominence, lumbar prominence, head-rib-pelvis positional relationship, head-pelvis relationship, shoulder level and scapula rotation. A high score means that the perceived deformity is high.
Baseline
Scoliosis Research Society 22
Time Frame: Baseline
It is a quality of life questionnaire which consists of 22 questions assessing 5 quality of life domains: Function, Pain, Self-Image, Mental health (5 questions), satisfaction (2 questions). Each category is rated on 5. The categories are summed and divided by 5 to have a total score on 5 points. 5 is the best score and 1 the worst
