Abstract

BackgroundIn the Global postural re-education GPR evaluation, posture alterations are associated with anterior or posterior muscular chain impairments. Our goal was to assess the reliability of the GPR muscular chain evaluation.

MethodsDesign: Inter-rater reliability study. Fifty physical therapists PTs and two experts trained in GPR assessed the standing posture from photographs of five youths with idiopathic scoliosis using a posture analysis grid with 23 posture indices PI. The PTs and experts indicated the muscular chain associated with posture alterations. The PTs were also divided into three groups according to their experience in GPR. Experts’ results after consensus were used to verify agreement between PTs and experts for muscular chain and posture assessments. We used Kappa coefficients K and the percentage of agreement %A to assess inter-rater reliability and intra-class coefficients ICC for determining agreement between PTs and experts.

ResultsFor the muscular chain evaluation, reliability was moderate to substantial for 12 PI for the PTs %A: 56 to 82; K: 0.42 to 0.76 and perfect for 19 PI for the experts. For posture assessment, reliability was moderate to substantial for 12 PI for the PTs %A > 60%; K: 0.42 to 0.75 and moderate to perfect for 18 PI for the experts %A: 80 to 100; K: 0.55 to 1.00. The agreement between PTs and experts was good for most muscular chain evaluations 18 PI; ICC: 0.82 to 0.99 and PI 19 PI; ICC: 0.78 to 1.00.

ConclusionsThe GPR muscular chain evaluation has good reliability for most posture indices. GPR evaluation should help guide physical therapists in targeting affected muscles for treatment of abnormal posture patterns.
