4 Possible explanations for treatment differences Literature published in languages other than English not cited by US researchersResearch typically with pts with mild AIS (< 30⁰) – which is generally not treated in USLack of support/interest promoting research in this area in USAll conservative methods often considered together as “alternative treatment”
5 History of the Schroth Method First developed in 1921 in GermanyAfter WWII, East Germany ordered a 3-year investigation of the methodResulted in the Schroth House being “nationalized” to allow access to more peopleIn 1955, moved to West GermanyIn 1961, Schroth Klinic opened in Bad Sobernheim.

16 Fusco et al (2011) Updated systematic review 20 studies showing: Detailed Appendix describing several exercise methods with pictures20 studies showing:Efficacy of exercise in reducing rate of progression &/or improving Cobb angleExercise effective in reducing brace prescriptionExercise improves strength, mobility, and balance
17 Fusco et al (cont)Physical exercises, if administered correctly, can prevent curve progression and prevent need for bracingPTs need to use specific exercises chosen according to strong scientific sourcesLiterature using unsound methodology and interventions can suggest that physical exercises are not effective, while scientifically-based physical exercises appear to be efficacious
18 PE Efficacy SummaryNeed for further studies, esp RCTs, following SOSORT criteria, to improve level of evidencePresent evidence is sufficient to consider PEs as an appropriate intervention for AIS3-D Autocorrection exercises appear to be best, but cannot yet support a specific programNot yet clear if inpatient vs outpatient or intrinsic vs extrinsic exercises most effective

Mean age ± 5.78 years.Surface topography (Formetric) was performed to measure trunk imbalance, surface rotation and lateral deviation before and after the treatment period.Improvements noted in mean trunk imbalance, lateral deviation mean and max, and surface rotation.
26 Schreiber et al (2013)The effects of a 6-month Schroth intervention for Adolescent Idiopathic Scoliosis (AIS): preliminary analysis of an ongoing randomized controlled trial31 patients with AIS, aged 10-18, with curves from 10°-45°, wearing a brace or not. 16 randomized to Schroth with standard care, and 15 to standard care alone (monitoring or bracing) for six months.Schroth exercises showed a small but positive influence on self-efficacy, self-image, pain and back muscle endurance.
27 Schroth TermsRib Hump – thoracic convexity. Most rotated, most prominent, and most posterior aspect at the apex. Ribs are rotated posteriorly and spread apart resembling the “inhalation position”Weak Side – ribs of the thoracic concavity are closer and lower, resembling the “exhalation position”. Ribs are rotated forward. Area appears flat and hollowed.
28 Schroth TermsLumbar Prominence – Lumbar convexity. Extensor muscles become overstretched and are displaced posteriorly. Leads to asymmetric waistline, full on convex side and accentuated on concave side.Weak Point – Lumbar concavity. TPs rotated anteriorly and muscles/connective tissues shortened. Waist is accentuated and pelvis appears shifted to this side.
29 Schroth TermsProtracted Shoulder – Shoulder on thoracic convex side is IR with inferior angle of scapula moved upward and tilted away from the ribcage.Retracted shoulder – Shoulder on thoracic concave side is ER and may sink into the thoracic cavity (scapula appears to wing, but this is really secondary to lack of rib support).May vary if a high thoracic or cervical compensatory curve is present
33 Schroth TermsVentral Flat Zone – Ventral aspect of the rib hump. Ribcage appears compressed; apical ribs closer and rotated posteriorly. Breast looks smaller.Ventral Prominence – Lower ribs of thoracic concave side are ventrally more prominent due to spinal rotation. Creates a “ventral rib hump”Prominent Hip – Pelvis deviated laterally as compensation for either T or L curve; causes hip adduction and raised iliac crest on that side. Increased WB on side opposite of prominent hip. (Prominent hip usually opposite side of primary curve).

44 Shoulder Block Level of shoulders Protraction/retraction Head position Upper thoracic/cervical curve
45 Schroth EvaluationForward Bend TestFlexibility – side shift, side bend, finger-to-floor measurement (lateral flexion), active rotation
46 Schroth Classification Named by position of thoracic convexity (right/left)Static standing posture determines primary curve (increased WB on side of primary curve)3c = primary thoracic curve4c = primary lumbar curvep = pelvic involvement (lateral shift, elevation away from primary convexity)
52 Schroth Postural Terms Habitual Posture – Resting scoliotic positionRelaxed Posture – Gravity-eliminated, lying. Side lying on the concave side of the main curve is preferred.For primary thoracic curves, on the thoracic concave side with knees flexedFor primary lumbar curves with small or no thoracic curve, on the lumbar concave sideFor double major curves, on thoracic concave side with lower leg flexed and upper leg extended to stretch the lumbar concavityAdd slide on positioning with supports
53 Schroth Postural Terms Conscious Posture - Postural correction as close to physiologically-typical posture as possible without requiring great physical or cognitive effort.Goal is to transfer this posture from exercise to dynamic alignment for daily lifeSymmetrical WB in sitting and standing (can depress the elevated side or raise the opposite side in sitting), correction of pelvic shift, shift of ribcage toward thoracic concave side
54 Schroth Postural Terms “Correct Posture” – Exercise position that approaches the flexibility threshold of the curve; attempts to reverse the curve.Requires concentration and coordination, correct breathing, and specific muscle tension and lengtheningVisual feedback provided with mirrors in front and backTherapist provides specific resistances and facilitation/elongation, instructions, and feedback.
57 Side Bending Used to test flexibility of curve and for mobilization Pt sitting on table, arms crossed, bring to neutral, upright spine as ableTest thoracic and lumbar curves bilaterallyMobilize by placing one hand on apex, other on opposite shoulderVentral, medial, cranial mobilization to passively correct rib hump
59 Side Shift Pt sitting in chair with UEs supported on table PT standing on thoracic concave sideOne hand reaches across front of pt and grasps rib hump; other hand at transitional vertebra (do not allow movement past this point)Translation of rib hump toward concave side (medial translation with some anterior derotation)
60 Derotation of the rib hump in sitting and supine
61 Derotation of Rib HumpIn sitting, passively retract shoulder. Mobilize rib hump ventral, medial, cranial.Pt can do this actively by bringing shoulder back, down, and externally rotatingIn supine, ER protracted shoulder, place support under retracted shoulder. Stabilize pelvis in posterior direction while mobilizing rib hump forward and medialPt can hold corrected position
62 Derotation of the Ventral Prominence in Sitting and Supine
63 Derotation of ventral prominence Pt sitting on chair with UEs supported on tableBring retracted shoulder forwardMobilize ventral prominence (thoracic concave side) posterior, lateral, cranialIn supine, ER protracted shoulderTherapist stands on opposite side. “Iron” prominence laterally and dorsallyCan use other hand to bring lumbar prominence forward
65 Derotation of the lumbar prominence In sitting, stabilize rib hump in anterior/medial directionMobilize lumbar prominence anteriorly and mediallyIn prone, place thumb over apical transverse process (most rotated/prominent TP)Place other hand on top of thumb and derotate anteriorly and mediallyCan also specifically mobilize segments to increase extension, rotation as needed
67 Stretching of thoracic concavity Lie on thoracic convex side with support under rib humpDo not lie on convexity if curve is severe or non-flexibleStretch soft tissue at least 20 secCan also provide massage, ribcage mobilization, fascial techniquesPt can actively pull top arm up on inhalation while therapist fixes rib downward with exhalation and holds; move segmentally up rib cage
69 Stretching of lumbar concavity Side lying on lumbar convexity over supportPassive mobilization and stretching of concavity
70 PNF Posterior Depression Side lying on thoracic concavity with support under lumbar convexityProvide forward/diagonal resistance to upper ischial tuberosityPt actively pushes into the resistance in posterior depression
71 Facilitated Breathing Hand placement on concavities (weak side, weak point, ventral flat zone)Can work in one area at a time or 2 simultaneously if patient is ablePalpate breathing and sync your breathing with patientBegin to provide resistance during inspiration in medial, forward directionAsk patient to breathe “out, back, and up” into your hands
72 Positioning Supports (towel roll, rice bag) Positioning Supports (towel roll, rice bag). Positions maintained minSupineUnder retracted shoulderUnder rib humpUnder lumbar prominenceUnder pelvis to derotate in a primary thoracic curve with pelvic involvement (not in primary lumbar curve; can worsen lumbar rotation)UE position based on curve type
73 Positioning Supports Prone Under forehead Under protracted shoulder Under ventral prominenceUnder pelvis to derotate in a primary thoracic curve with pelvic involvement (not in primary lumbar curve; can worsen lumbar rotation)
74 Positioning Supports Side lying Lie on side of thoracic concavity Roll support under lumbar convexityBottom arm above head; head rests on armActive exercise – Depress upper leg caudally, lift off surfaceAdd slide for opposite side
75 Positioning Corrections UE Positioning for Symmetrical thoracic spine:90 degree abduction with elbows flexed at 90 degrees.Isometric contraction of scapular adductor and serratus anterior corrects sagittal plane deformity (shoulders positioned back for kyphosis reduction, shoulders positioned forward for flat back correction)
76 Positioning Corrections Positioning for thoracic curve:UE on thoracic convex side at 90 degree abduction/90 degree elbow flexion.Patient can actively ER and adduct scapula to self-mobilize rib humpUE on thoracic concave sidePositioned diagonally to stretch the concavity
77 Positioning Corrections Positioning for lumbar curve:Active depression of pelvis in caudal direction on lumbar concave side to stretch lumbar concavityPelvic shift away from the prominent hip in curves with pelvic involvement. Body weight should be transferred to side of prominent hip.
78 Conscious PostureGoal is to teach the conscious posture so that it can be maintained without supports throughout the dayCan use breathing corrections as self-facilitation of conscious posturePelvic symmetry, equalize WB, bring convexities medial and anteriorChange postural habits – overhead reach with UE of thoracic concave side, WB on UE of thoracic concave side in sitting for elongation
79 Positioning for elongation Right thoracic, Left lumbar curves IncorrectCorrect
80 Pelvic CorrectionsFeet parallel. Knees unlocked. Pelvis balanced over center of feet.Adjust anterior/posterior tilt to physiological position (about 30 degrees).Lateral shift of pelvis to correct prominent hip (Increase WB away from primary curve, shift pelvis toward primary curve).Derotate the pelvic block (but do not correct a primary lumbar curve with pelvic involvement – can increase the lumbar rotation)Depress elevated hip. In sitting, can elevate the opposite side with passive support.
81 Exercise Sequencing Positioning Elongation of spine with normal breathingCorrective breathing. Use isometric tension to hold corrected posture on exhalation as able.Dynamic exercise performed during exhalation for predetermined # of reps.Rest between sets maintaining conscious posture.ie 4 sets of 6 reps (each repetition = 1 breathing cycle)
