Physiotherapeutic Scoliosis-Specific Exercises (PSSE-Schroth) can reduce the risk for progression during early growth in curves below 25°: prospective control study.

BACKGROUND: The main treatment aim in mild scoliosis is to prevent progression and if possible, to avoid bracing. Physiotherapeutic Scoliosis Specific Exercises (PSSE) are curve pattern specific exercises, based on 3D self-correction and activities of daily living training. AIM: The objective of this study was to evaluate the efficacy of PSSE - Schroth, as an exclusive treatment, during the riskiest period of rapid growth. DESIGN: Prospective control study. SETTING: Outpatient treatment. POPULATION: Adolescents with scoliosis. METHODS: One hundred and sixty-three patients (148 girls,15 boys; mean age 12.6 years, Risser sign 1.1, thoracic (Th) Cobb angle 20.8° and lumbar/thoracolumbar (L/TL) Cobb angle 20.7°) performed PSSE - Schroth exercises in our clinic. They were asked to regularly attend supervised sessions and to follow a home-program at least 5 times per week. Our inclusion criteria were Cobb angle 15°-25°, Risser 0-2 and angle trunk rotation (ATR) >5°, measured by scoliometer. The outcome parameters were the Cobb angle before and after the intervention (improvement or progression were defined as angle difference more than 5°) and the number of patients that finally needed a brace. Average follow-up time was 29.4 months. Control group was consisted of 58 patients (54 girls, 4 boys; mean age 13.1 years, Risser sign 0-2, Th Cobb 19.4°, L/TL Cobb 19.2°), that were retrospectively analyzed and performed general or no exercises. Compliance was self-reported. Statistical analysis was performed by paired t-test. RESULTS: For PSSE - Schroth group, 103 patients (63.2%) remained stable, 39 (23.9%) improved and 21 (12.9%) worsened. The success rate (87.1%) was significantly higher compared to Control group (P=0.002), where 15 subjects (25.9%) were stable and 43 (74.1%) worsened. Similarly, 16 patients (9.8%) from PSSE - Schroth group finally needed a brace, while 39 (67.2%) from control group (P=0.01). CONCLUSIONS: PSSE - Schroth reduced the risk of progression in Adolescent Idiopathic Scoliosis (AIS) patients, during early growth. Our results are in accordance with the recently published literature, showing the effectiveness of PSSE and their superiority compared to general exercises or natural history. CLINICAL REHABILITATION IMPACT: Scoliosis specific exercises can be the first step of scoliosis treatment in mild curves, to avoid progression and bracing.

Cross-cultural validation of the Italian Spine Youth Quality of Life questionnaire: the ISYQOL international.

BACKGROUND: Adolescent idiopathic scoliosis and its treatments can severely impact health-related quality of life. The Italian Spine Youth Quality of Life (ISYQOL) questionnaire, initially developed in Italian and tested on Italian people, was created to measure quality of life in young persons with spine changes. ISYQOL was created using the Rasch analysis, a modern psychometric technique for questionnaires' assessment and development, which showed that the ordinal scores of the ISYQOL Italian version provide sound quality of life measures. AIM: The current work aims to evaluate the cross-cultural equivalence of the ISYQOL questionnaire in seven different countries. DESIGN: Cross-sectional, international, multi-centre study. SETTING: Outpatient clinic. POPULATION: Five hundred fifty persons with adolescent idiopathic scoliosis from English Canada, French Canada, Greece, Italy, Spain, Poland, and Türkiye. METHODS: The ISYQOL Italian version was translated into six languages with the forward-backwards procedure. The conceptual equivalence of the items' content was verified, and any inconsistency was resolved by consensus. The Rasch analysis was used here to evaluate that ISYQOL translations retained the good measurement properties of the Italian version of the questionnaire. In addition, the Differential Item Functioning (DIF) was checked to assess the psychometric equivalence of the ISYQOL items in patients from different countries. RESULTS: Four items of the translated ISYQOL were dropped from the questionnaire since they did not contribute to measuring due to their poor fit to the model of Rasch. Seven items were affected by DIF for nationality, a finding pointing out that these items do not work the same (i.e. are not equivalent) in the different countries. Thanks to the Rasch analysis, the DIF for nationality was amended, and ISYQOL International was eventually obtained. CONCLUSIONS: ISYQOL International returns interval quality of life measures in people with adolescent idiopathic scoliosis with high cross-cultural equivalence in the tested countries. CLINICAL REHABILITATION IMPACT: Rigorous testing showed that ISYQOL International ordinal scores return quality of life measures cross-culturally equivalent in English and French Canada, Greece, Italy, Spain, Poland, and Türkiye. A new, psychometrically sound patient-reported outcome measure is thus available in rehabilitation medicine to measure health-related quality of life in idiopathic scoliosis.

Brace and Physiotherapeutic Scoliosis Specific Exercises (PSSE) for Adolescent Idiopathic Scoliosis (AIS) treatment: a prospective study following Scoliosis Research Society (SRS) criteria.

BACKGROUND: A growing scientific evidence for conservative treatment of AIS has recently proved that bracing is superior to natural history. Our aim was to investigate the effectiveness of a combined treatment with brace and PSSE for AIS. METHODS: Prospective study, following SRS research inclusion criteria (> 10 years, 25ο - 40ο, Risser 0-2, < 1-year post-menarche, no prior treatment). 102 consecutive patients (87 females-15 males, mean age 12.8 years, Risser 0.48, Cobb Thoracic 29.2ο, Lumbar 27.8ο) received treatment with Cheneau brace and PSSE. Average follow-up time was 26.4 months. A scale from A to C was used to evaluate compliance with brace and PSSE (A: full-compliant, B: partially compliant, C: non-compliant). 7 subjects dropped-out (6.8%), so finally 95 patients included for statistical analysis, using paired t-test. RESULTS: Sixty-two patients (65.3%) remained stable, 22 improved > 5ο (23.2%) and 11 progressed (11.5%). In-brace correction (IBC) was 49.7% for thoracic and 61.7% for lumbar curves. Analysis of progressed cases revealed that IBC (31.7% for thoracic and 34.4% for lumbar curves) and compliance (81.8% C for brace, 63.6% C for PSSE) was lower than average. Group A for treatment compliance (65.3%), showed significantly better results (70.9% stable, 29.1% improved, 0% progressed). CONCLUSION: A combination of bracing and PSSE can effectively treat AIS, according to SRS inclusion criteria. 88.5% of patients avoided progression > 5ο and only 6.4% overpassed 40ο. IBC and compliance are the most important prognostic factors for successful treatment result. Early detection of AIS is also necessary for increased possibilities of effective conservative treatment.

Bracing In The Treatment Of Adolescent Idiopathic Scoliosis: Evidence To Date.

Brace effectiveness for adolescent idiopathic scoliosis was controversial until recent studies provided high quality of evidence that bracing can decrease likelihood of progression and need for operative treatment. Very low evidence exists regarding bracing over 40ο and adult degenerative scoliosis. Initial in-brace correction and compliance seem to be the most important predictive factors for successful treatment outcome. However, the amount of correction and adherence to wearing hours have not been established yet. Moderate evidence suggests that thoracic and double curves, and curves over 30ο at an early growth stage have more risk for failure. High and low body mass index scores are also associated with low successful rates. CAD/CAM braces have shown better initial correction and are more comfortable than conventional plaster cast braces. For a curve at high risk of progression, rigid and day-time braces are significantly more effective than soft or night-time braces. No safe conclusion on effectiveness can be drawn while comparing symmetrical and asymmetrical brace designs. The addition of physiotherapeutic scoliosis-specific exercises in brace treatment can provide better outcomes and is recommended, when possible. Despite the growing evidence for brace effectiveness, there is still an imperative need for future high methodological quality studies to be conducted.

Long-Term Effects of Untreated Adolescent Idiopathic Scoliosis: A Review of the Literature.

Currently, adolescent idiopathic scoliosis (AIS) is principally regarded as benign, but some researchers have cited serious or extreme effects, including severe pain, cardiopulmonary compromise, social isolation, and even early death. Therefore, exploration of the long-term effects of AIS, the most common type of idiopathic scoliosis, is warranted. The purpose of this review was to examine the long-term studies on the natural history of AIS and/or reviews concerning the long-term effects of untreated AIS. A PubMed search was conducted using the key words idiopathic scoliosis, long-term effects and idiopathic scoliosis, natural history. For further analysis, references cited in those studies were reviewed for additional, related evidence not retrieved in the initial PubMed search. A review of the pertinent bibliography showed that older natural history studies did not distinguish between late-onset scoliosis (referred to in this paper as AIS) and early-onset scoliosis (EOS). The more recent studies offer such important distinction and reach to the general conclusion that untreated AIS does not lead to severe consequences with respect to signs and symptoms of scoliosis. It is possible that earlier studies may have included patient populations with EOS, leading to the perception of untreated scoliosis as having an unusually high morbidity rate. Studies on the long-term effects of AIS that specifically excluded EOS patients conclude that AIS is a benign disorder. This indicates that for research and reporting purposes, it is important to distinguishing between AIS and EOS. This will allow the practitioner and patient and their families to decide on an optimal treatment plan based on the most appropriate prognosis.

Bracing for Adolescent Idiopathic Scoliosis (AIS) and Scheuermann Kyphosis: the issue of overtreatment in Greece.

BACKGROUND: Most recent publications have provided evidence for brace treatment in spinal deformities. The purpose of this study was to evaluate the rate of overtreatment for AIS and Kyphosis in Greece, according to the Society on Scoliosis Orthopedic Rehabilitation Treatment (SOSORT) and the Scoliosis Research Society (SRS) guidelines for brace treatment. To date, this is the first study to investigate overtreatment percentage in a group of patients with spinal deformities. METHODS: Cross-sectional study design and data analysis were performed in a group of patients that received treatment in a private clinic, in 2014. Of 289 patients treated with a brace, 167 young adolescents (126 females - 41 males, mean age 15, 7 years) were eligible for inclusion criteria (age 9-18 years, brace wearing). Overtreatment was defined as the unnecessary use of brace according to the international indications for brace treatment. Overtreatment was assessed by a BSPTS - Schroth certified physiotherapist. The brace prescription was made by 34 medical doctors from different geographical areas of Greece. RESULTS: The data analysis revealed that 71 out of 167 subjects (42,5 %) had received some kind of overtreatment. A further analysis showed that in the AIS subgroup, 20 subjects (16,9 %) had Cobb angles < 20°, 7 subjects (5,9 %) had Cobb angles 20 - 25° but good prognosis, 12 subjects (10,2 %) started bracing after Risser 4, and 12 subjects (10,2 %) had delayed brace weaning. It is noticeable that 8 subjects (6,8 %) were at Risser 5 with Cobb angle < 20° and were prescribed a brace. In the Kyphosis subgroup, 11 subjects (22,5 %) showed no signs of Scheuermann's disease, 3 subjects (6,1 %) started bracing after Risser 4 or 5, and 6 subjects (12,2 %) had delayed brace weaning. CONCLUSIONS: An extremely high rate of overtreatment (42, 5 %) was identified in a random group of adolescents treated with a brace for AIS and Kyphosis. Overtreating a child with a brace can cause social, financial and psychological problems. The present study pinpoints the need for an evidence-based approach to conservative treatment of idiopathic scoliosis and kyphosis. Overtreatment can be avoided when the indications are strictly based on the guidelines published internationally.
