Purpose The purpose of this study was to evaluate the efficacy of our technique that allows direct visualization of seating of suspensory devices in anterior cruciate ligament (ACL) reconstruction. Materials and Methods Three different suspensory devices (TightRope RT, RetroButton, and EndoButton) were used in ACL reconstruction using 3 different techniques (outside-in, anteromedial [AM] port...

OBJECTIVE To evaluate the reliability of 4 functional tasks relevant to wheelchair seating. DESIGN Within-subject and between-rater comparisons. SETTING Rehabilitation center in Canada. PARTICIPANTS Two separate convenience samples of 10 male wheelchair users. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The 4 functional tasks were timed forward wheeling, ramp ascent, forward v...

Pressure sores are a major problem frequently encountered by persons who use wheelchairs. Custom seat design, including contoured seating and various modular seating devices, has become an important option for pressure relief, especially when the market size is small and the variations of individual needs and requirements are large. An alternative approach in custom seating design for pressure ...

It has been reported in the literature that impingement of the casting at the axial-occlusal line angle of the tooth preparation may be a major cause of incomplete seating following cementation. It has been suggested that an additional coat of spacer applied to these areas on the laboratory die before the fabrication of the casting may alleviate this discrepancy. This study evaluated the effect...

Sitting for prolonged periods of time increases seating interface pressures, which is known to increase the risk of developing pressure ulcers. Those at risk of developing pressure ulcers are advised to perform pressure relieving movements such as "pushups" or "forward leans" in order to reduce the duration and magnitude of pressure acting on the vulnerable ischial tuberosity region. The aim of...

We address the problem of enumeration of seating arrangements of married couples around a circular table such that no spouses seat next to each other and no k consecutive persons are of the same gender. While the case of k = 2 corresponds to the classical problème des ménages with a well-studied solution, no closed-form expression for number of arrangements is known when k ≥ 3. We propose a nov...

In high quality industrial processes, the control chart is design based on cumulative count of conforming (CCC) items is very useful. In this paper, the performance of CCC-r chart with variable sampling intervals (CCC-rVSI chart) in the presence ofinspectionerrors isinvestigated. The efficiency of CCC-rVSI chart is compared with CCC-r chart with fixed sampling interval (CC...
