زمينه و هدف: اسكوليوز ناهنجاري است كه سيستم‌هاي مختلف بدن را درگير مي‌كند و بر حركات بدن ازجمله راه‌رفتن تأثير مي‌گذارد؛ ازاين‌رو، هدف از پژوهش حاضر بررسي اثر تمرينات شروت بر طول گام نوجوانان مبتلا به اسكوليوز بود.
روش بررسي: اين پژوهش نيمه‌تجربي با طرح پيشآزمون و پس‌آزمون بود. پژوهش حاضر بر 30 نوجوان مبتلا به اسكوليوز مركز توان‌بخشي اصفهان با ميانگين سني 3٫73±14٫85 سال، شاخص BMI 1٫34±20٫41 كيلوگرم بر مجذور متر و ميزان زاويهٔ كوب 2٫12±16٫54، در گروه‌هاي مداخله و گواه انجام شد. برنامهٔ تمريني گروه مداخله به‌مدت هشت هفته به‌عنوان متغير مستقل و طول گام كه با استفاده از فيلم اندازه‌گيري شد، به‌عنوان متغير وابسته در نظر گرفته شد. به‌منظور بررسي تفاوت بين گروه‌هاي مداخله و گواه از آزمون تي‌مستقل و براي تفاوت پيشآزمون و پس‌آزمون هر گروه از آزمون تي وابسته با سطح معناداري 0٫05 در نرم‌افزار SPSS نسخۀ 23 استفاده شد.
يافته‌ها: باتوجه به نمرات پيشآزمون و پس‌آزمون در گروه مداخله، طول گام اين افراد به ميزان 8٫3 سانتي‌متر افزايش يافت و براساس نتايج آزمون تي وابسته، بين نمرات پيشآزمون و پس‌آزمون در گروه مداخله تفاوت معنادار وجود داشت (0٫001=p)؛ ولي در گروه گواه نتيجه‌ٔ اين آزمون معنادار نبود؛ همچنين نتايج آزمون تي مستقل نشان‌دهنده‌ٔ وجود تفاوت معنادار بين گروه‌هاي مداخله و گواه بود (0٫002=p).
نتيجه‌گيري: باتوجه به افزايش 8٫3 سانتي‌متري طول گام بيماران اسكوليوزي اين تحقيق درمي‌يابيم، تمرينات شروت بر طول گام نوجوانان مبتلا به اسكوليوز سه‌قوسي با قوس اصلي ناحيهٔ توراسيك تأثير معناداري دارد.

Background & Objectives: Adolescent scoliosis is defined as a spinal deformity in a skeletally mature patient with a Cobb angle of >10° in the coronal plane. Scoliosis is a condition that occurs in the spinal column at three–plane, involving the skeletal, muscular, and nervous systems. It
ultimately affects the biomechanics of body movements, such as walking, running, and jogging. Muscular imbalance in different parts of the spine is among the causes of interstitial scoliosis; it can appear as weak and short patterns on the sides of the spine, causing side–and–sided
anomalies in the spinal column of the individual. Different approaches are available to correct this condition. In this regard, the Schroth approach
claims to provide a favorable effect on the correction of adolescent idiopathic scoliosis. Therefore, the current study aimed to investigate the
effect of Schroth corrective exercise on straight length in adolescents with scoliosis.
Methods: This was a quasi–experimental study with a pretest–posttest and a control group design. This research was performed on 30 adolescents
with scoliosis. The mean±SD age of the study subjects was 14.85±3.73 years; their mean±SD Body Mass Index (BMI) equaled 20.41±1.34
kg/m2, and their mean±SD Cobb angle was measured as 16.54±2.12 degree. The inclusion criteria of the study included having triangular thoracic
scoliosis, having a thoracic arch angle of 10–20 degrees respecting the scale of Cobb angle and the radiograph in the patients’ medical records,
and an age range of 12–18 years. The exclusion criteria of the study were non–participation in two consecutive training sessions and three non–
consecutive sessions, the lack of proper cooperation, pain, and dissatisfaction to continue research. The 8–week training program of the
intervention group was considered as an independent variable. The step length, i.e., measured using video recording by a camera, was considered
as a dependent variable. For investigating differences between the control and intervention groups, we used the Independent Samples t–test.
Besides, the differences between pretest and posttest stages were examined applying Dependent Samples t–test at the significance level of 0.05
in SPSS.
Results: The results of the Dependent Samples t–test revealed a significant difference between the pretest and posttest values of the intervention
group (p=0.001); however, there was no significant difference between the pretest and posttest values of the control group (p=0.106). The results
of the Independent Samples t–test suggested a significant difference between the control and intervention groups (p=0.002). The stride length of
the intervention group has increased by 8.3 cm. The effectiveness of this intervention on Cohen’s D scale was calculated as 1.66, indicating the
high efficacy of this exercise intervention.
Conclusion: According to the present study data, there was an increase of about 8.3 cm in the stride length of the study subjects. Thus, Schroth corrective exercise significantly impacted the stride length of adolescents with triple–curve thoracic idiopathic scoliotic.
