Comparisons Of Static And Dynamic Balance Following Training In Aquatic And Land Environments, Aimee E. Roth, Michael G. Miller, Marc Richard, Donna Ritenour, Brenda L. Chapman

Human Performance and Health Education Faculty Research

Context: It has been theorized that aquatic balance training differs from land balance

training. Objective: To compare the effects of balance training in aquatic and

land environments. Design: Between-groups, repeated-measures design. Setting:

Biomechanics laboratory and pool. Participants: 24 healthy subjects randomly

assigned to aquatic (n = 8), land (n = 10), or control (n = 6) groups. Intervention:

Four weeks of balance training. Main Outcome Measures: Balance was measured

(pre, mid, post, follow-up). COP variables: radial area, y range, x range in single

leg (SL), tandem (T), single leg foam (SLF), and tandem form (TF) stance. Results:

A significant condition …

Use Of Item Response Analysis To Investigate Measurement Properties And Clinical Validity Of Data For The Dynamic Gait Index, Yi-Po Chiu, Stacy L. Fritz, Kathye E. Light, Craig A. Velozo

Physical Therapy Faculty Research

Background and Purpose. The Dynamic Gait Index (DGI) is a standardized clinical assessment that aids in evaluating a subject’s ability to modify gait in response to changing demands. The purpose of this study was to use Rasch measurement theory to examine whether the DGI rating scale meets suggested psychometric guidelines, whether the hierarchical order of DGI tasks is consistent with a clinically logical testing procedure, and whether the DGI represents a unidimensional construct. Subjects. Subjects were 84 community-dwelling male veterans (age range=64–88 years; mean±SD=75±6.47 years). Methods. Data were retrieved retrospectively from the participants’ clinical records. The Rasch measurement model with …

The Relationship Of Cervical Joint Position Error To Balance And Eye Movement Disturbances In Persistent Whiplash, Julia Treleaven, Gwendolen Jull, Nancy Low Choy

Nancy Low Choy

Cervical joint position error (JPE) has been used as a measure of cervical afferent input to detect disturbances in sensori-motor control as a possible contributor to a neck pain syndrome. This study aimed to investigate the relationship between cervical JPE, balance and eye movement control. It was of particular interest whether assessment of cervical JPE alone was sufficient to signal the presence of disturbances in the two other tests. One hundred subjects with persistent whiplash-associated disorders (WADs) and 40 healthy controls subjects were assessed on measures of cervical JPE, standing balance and the smooth pursuit neck torsion test (SPNT). The …
