The challenges and opportunities of laboratory regionalization.

These are some of the major historical trends and rationale for the sea change in laboratory medicine today. The creation of cooperative regional networks and consolidated regional laboratories potentially can: 1) Pool the technologic strengths of individual laboratories across a region; 2) Create economies of scale by combining capacities for certain procedures; 3) Lower unit costs by increasing volumes of business from nonpatients; 4) Span all of the traditional testing venues along the new expanding continuum of care. The authors in this monograph will take the saga forward in time, outlining critical organizational, technologic, and strategic aspects of the newly evolving laboratory of the 21st century.

Selected comparisons between experienced and non-experienced individuals during manual wheelchair propulsion.

The present study was undertaken to identify potential errors that might arise from combining able-bodied individuals with wheelchair dependent individuals to form larger sample sizes when studying manual wheelchair propulsion. Five able-bodied and five wheelchair dependent individuals, ranging in age from 24 to 36, propelled a wheelchair on a dynamometer at three different velocities. Of the nine variables (at three different velocities) investigated, significant differences (p < 0.05) were obtained for three physiological characteristics: propulsion efficiency, peak oxygen consumption, and energy input all at high velocity, and for four technique characteristics: at low velocity (propulsion time), and at high velocity (propulsion time, push angle, work per stroke). The results suggest that able-bodied individuals should not be used to increase the size of subject pools when doing studies which include these variables.
