ObjectivesParadoxical vocal fold motion (PVFM) consists of intermittent adduction of the vocal folds during inspiration, resulting in stridor and worsened by anxiety and stress. The purpose of this study was to assess the impact of PVFM on quality of life in our pediatric patient population.Study DesignThis is a prospective, descriptive survey study.MethodsThirty-nine consecutive patients (ages 12–17 years) presenting with a PVFM diagnosis for respiratory retraining sessions with speech-language pathology were recruited. Patients completed a brief demographic questionnaire and the Short Form 36, version 2, a validated tool for measuring health-related quality of life.ResultsThere were 31 (79%) girls and 8 (21%) boys with a mean age of 15.5 years. Subjects reported regular participation in competitive extracurricular activities, including track or cross country (30.8%), swimming (17.9%), and cheerleading or dancing (15.4%). Of the patients in the study, 46.2% were straight-A students. On the SF-36 (population averages normalized to a score of 50), the general health of patients with PVFM was better than that of the general population (53.27); however, their physical health limited their role activities more severely (42.82). In addition, a greater proportion of the group with PVFM was at risk for first-stage depression screening when compared with the general population (28% versus 18%).ConclusionsWe demonstrate a measurable detrimental impact of PVFM on health-related quality of life. This is consistent with previously published literature showing a preponderance of females with PVFM, most of whom are high achievers academically and athletically.

Upper extremity motion during gait in adolescents with structural leg length discrepancy—An exploratory study
Publication date: March 2017

Author(s): Fabiola Angelico, Marie Freslier, Jacqueline Romkes, Reinald Brunner, Stefan Schmid
Background and purposeDepending on the extent of a structural leg length discrepancy (LLD), several compensatory mechanisms take place in order to maintain function and to optimize energy consumption during gait. However, studies describing the influence of a structural LLD on upper limb motion are lacking. The current study therefore aimed at the evaluation of upper limb motion during gait in LLD patients compared to healthy controls.MethodsMotion capture data from 14 patients with structural LLD and 15 healthy controls that were collected during barefoot walking at a self-selected speed were retrospectively analyzed. Specifically, kinematic parameters of the shoulder and elbow joints as well as the trunk segment were investigated and considered in relation to a minimal clinically important difference of 5°.ResultsThe shoulders in LLD patients were kept constantly in a more extended and at initial contact in a more adducted position as compared to healthy controls. In addition, the patients’ elbow joints showed increased flexion motion and the trunk segment indicated a constant trunk lateral-flexion and axial rotation tendency towards the affected side.ConclusionsPatients with structural LLD indicated clinically relevant secondary deviations in shoulder and elbow motion. While some of these deviations were most likely passive physical effects, others might have occurred as active strategies to maintain balance or to regulate total body angular momentum. These findings contribute to the understanding of secondary gait deviations induced by a structural LLD and might serve as a basis for further investigations using complex musculoskeletal models.
