Reliability Of Center Of Pressure Measures For Assessing The Development Of Sitting Postural Control, Anastasia Kyvelidou, Regina T. Harbourne, Wayne A. Stuberg, Junfeng Sun, Nikolaos Stergiou

Journal Articles

Objectives: To determine the reliability of linear and nonlinear tools, including intrasession and intersession reliability, when used to analyze the center of pressure (COP) time series during the development of infant sitting postural control.

Design: Longitudinal study.

Setting: University hospital laboratory.

Participants: Typically developing infants (N33; mean SD age at entry in the study, 152.417.6d).

Interventions: Not applicable.

Main Outcome Measures: Infants were tested twice in 1 week at each of the 4 months of the study. Sitting COP data were recorded for 3 trials at each session (2 each month within 1 week). …

Differences In Upper Body Posture And Postural Muscle Activation In Females With Larger Breast Sizes, Mindy Bennett

Boise State University Theses and Dissertations

Breast hypertrophy is a common medical condition whose morbidity has increased over recent decades. Symptoms of breast hypertrophy often include musculoskeletal pain in the neck, back and shoulders, and numerous psychosocial health burdens. To date, reduction mammaplasty (RM) is the only treatment shown to significantly reduce the severity of the symptoms associated with breast hypertrophy. However, due to a lack of scientific evidence in the medical literature justifying the medical necessity of RM, insurance companies often deny requests for coverage of this procedure. Therefore, the purpose of this study is to investigate biomechanical differences in the upper body of women …

Factors Affecting Functional Reach Scores In Youth With Typical Development, Kathleen G. Volkman, Nikolaos Stergiou, Wayne A. Stuberg, Regina T. Harbourne, Daniel Blanke, Julie Stoner

Journal Articles

Purpose: Functional Reach Test scores were examined for the effects of traditional and alternate methods and subject characteristics.

Methods: Eighty subjects aged 7 to 16 years were tested. Effects of measurement method (from finger-to-finger or from toe-to-finger) and style of reach (1 or 2 arms) were investigated. Five subject variables were analyzed for interactions among the methods and groups defined by subject characteristics.

Results: Measurement method and style of reach showed a significant interaction. Interaction of method with subject characteristics was significant for age, height, and base of support only. Height groups by quartile were significantly different and scores increased …
