Background/Objectives: This is a study of adolescents with idiopathic scoliosis (IS), treated by the Functional Individual Therapy of Scoliosis (FITS) method. The hypothesis was that active parental involvement in the treatment process enhances the outcomes of therapy. Materials and Methods: A total of 208 adolescent girls with IS were examined and divided into two groups. Only in Group I were the parents present. Trunk morphology before and after was evaluated by measuring change of the Anterior Trunk Symmetry Index (ATSI), Posterior Trunk Symmetry Index (POTSI), Posterior Trunk Symmetry Index in Correction (POTSI COR), and the angle of trunk rotation (ATR). Results: Statistically significant improvements in ATSI values were observed in both groups (Group I: p < 0.001; Group II: p = 0.001). POTSI values showed improvement only in Group I (p < 0.001). Similarly, POTSI COR values improved significantly in Group I (p < 0.001). ATR improved significantly better in Group I. Conclusion and Significance: Children with IS who underwent specific physiotherapy demonstrated better outcomes when their parents actively participated in the therapy.

Background and Objectives: Physiotherapeutic Scoliosis-Specific Exercises (PSSE) are recognized treatment methods for idiopathic scoliosis, focused on correcting three-dimensional postural abnormalities. Objective indices such as Angle of Trunk Rotation (ATR), Anterior Trunk Symmetry Index (ATSI), and Posterior Trunk Symmetry Index (POTSI) enable precise assessment of clinical changes, while the Trunk Appearance Perception Scale (TAPS) reflects the patient’s subjective perception of their posture. Combining these data allows for a comprehensive assessment of the effects of therapy after intensive 5-day inpatient rehabilitation. We aimed to assess the improvement in the patients’ clinical appearance and compare objective and subjective trunk assessment indicators after intensive 5-day inpatient rehabilitation, treated by PSSE, according to the Functional Individual Therapy of Scoliosis (FITS) Method. Materials and Methods: This retrospective study included 75 patients with idiopathic scoliosis who participated in a 5-day inpatient rehabilitation, treated by FITS Method. The average age was 13.5 years, and 63% of the girls were after menarche. The mean Cobb angle was 27.41° in single-curve scoliosis and 31.03° in double-curve scoliosis (31.24° in the thoracic spine, 30.82° in the lumbar spine), Risser test 2, and ATR was 7.1° in the thoracic spine and 4.6° in the lumbar spine. Forty-nine patients wore a brace. At the beginning and end of inpatient care, objective assessments were performed, including ATR at the peak of the scoliosis using the Adams test and photoregistration of the trunk in the front and back standing positions—ATSI and POTSI. A subjective assessment was also performed using the TAPS. Results: A statistically significant difference was demonstrated after therapy in the ATSI (p < 0.001) and POTSI (p = 0.008) values. A reduction in the ATR in the thoracic spine was observed (p < 0.001). The TAPS questionnaire demonstrated a statistically significant difference in the values of all indicators measured before and after therapy: in the frontal plane SET 1 (p = 0.002), in the transverse plane SET 2 (p = 0.042), and in the frontal plane SET 3 (p = 0.028). A statistically significant negative correlation was demonstrated between objective and subjective indicators after therapy: ATR Th vs. TAPS-SET 2 (−0.45) (p < 0.001) and ATSI vs. SET 3 (−0.29) (p = 0.011). Conclusions: The subjective assessment of trunk appearance correlates with the objective assessment, except for SET 1 vs. POTSI. Patients who noticed a change in their posture can expect confirmation in objective clinical tests. FITS Method positively influences the improvement of subjective and objective assessments of idiopathic scoliosis patients during the short term of intensive care.

Background/Objectives: Idiopathic scoliosis affects musculoskeletal biomechanics and trunk appearance. Patient-reported outcome measures, including the Trunk Appearance Perception Scale (TAPS), are important for assessing health-related quality of life and monitoring treatment. This study compared children’s and parents’ perceptions of trunk appearance before and after 5-day scoliosis-specific exercises according to Functional Individual Therapy of Scoliosis (FITS Method). Additionally, changes in the perception of trunk appearance by patients and parents were evaluated in relation to brace use. Methods: Ninety children with idiopathic scoliosis (74 girls and 16 boys; mean age: 13.6 ± 2.1 years) and their parents participated. Sixty-two children used a Chêneau brace. Most participants (n = 71) had double-curve scoliosis; the mean thoracic and lumbar Cobb angles were 32.5° ± 12.9 and 32.2° ± 13.0, respectively. Children and parents completed the TAPS at the beginning and end of the program. Results: After the 5-day rehabilitation program, TAPS scores were significantly higher in both children and their parents than at baseline (p < 0.001). The change in scores from before to after therapy differed significantly between children and parents (p = 0.046). In the group of children treated with braces, the assessment of the impact was statistically significant for both the children and their parents (p < 0.001 in both cases). In the group of children not treated with braces, the assessment was statistically significant only for the parents (p = 0.003). Conclusions: 1. Following a 5-day rehabilitation stay, a beneficial change was observed in the perception of trunk appearance among children with idiopathic scoliosis and their parents. 2. Parents rated the change after the program slightly more positively than the children themselves. 3. The perception of trunk appearance among children treated with and without a brace was similar after the stay.
