It would be safe to assume that the integrity of a full coverage restoration is directly related to its marginal fit. Complete, unimpaired seating of a full coverage restoration can be significantly affected by hydraulic pressure from the cement. Hydraulic pressure, created by seating a restoration, especially a well-fitting one, can result in a final marginal gap that is clinically unacceptabl...

Background: Advances in the care and rehabilitation of patients with spinal cord injuries (SCI) have resulted in extended survival. As SCI patients age, chronic lower extremity ischemic complications are resulting in amputations. The literature relating to lower extremity amputation and prosthesis in SCI patients is sparse. Limb amputation may cause weight distribution imbalances, leading to ba...

This study examined the performance of a booster seat in different seating configurations in side-impact hyGe sled tests (crash severity 30 km/h) with two attachment systems: a standard seatbelt and ISOfix (rigid). The objectives of the study were twofold: (i) to identify the relative benefits of ISOfix attachment compared with seatbelt attachment of a near-side booster seat in a 3-abreast seat...

As a part of classroom management, teachers face the question of how and where to seat their students. However, it is far from clear what considerations teachers have when making seating arrangements. Therefore, in this study seating arrangement considerations from 50 teachers in grades 4–6 of elementary school were assessed. In Phase 1, teachers were interviewed about their goals and considera...

The American}ournal 0/ Occupational Therapy W hen designing and providing wheelchair seating systems, the rehabilitation team aims for a balance of components that will provide external support for the person who, because of lack of neuromotor or neuromuscular control, cannot independently maintain a seated posture. Over the past 10 years, many new approaches to fabricating seat and back compon...

CONTEXT Controversy exists about the most appropriate seating position for children with cerebral palsy (CP) to promote energy conservation and maximize upper-extremity function. EVIDENCE ACQUISITION Sixteen journal articles published after 1980 were identified by searching allied health, medical, and occupational and physical therapy data bases and evidence-based medicine reviews using speci...

BACKGROUND This study investigated the effects of obesity on attentional resources allocated to postural control in seating and unipedal standing. METHODS Ten non obese adults (BMI = 22.4±1.3, age = 42.4±15.1) and 10 obese adult patients (BMI = 35.2±2.8, age = 46.2±19.6) maintained postural stability on a force platform in two postural tasks (seated and unipedal). The two postural tasks were ...

OBJECTIVE The objective of this study was to examine the effectiveness of a new user-adjustable wheelchair seating system designed to relieve discomfort for long-duration wheelchair users. DESIGN This objective was carried out using the newly developed Tool for Assessing Wheelchair disComfort (TAWC) as the primary outcome measure. Two wheelchair users each tested two different designs and fee...

Driving comfort is important for any class of vehicle drivers. Seating very drivers who are undergoing extended period driving and its associated side effects include higher risk back problems, discomfort in neck, shoulder thighs. A good sitting position correct posture to reduce various work related injuries. There several occupational factors that may affect the performance heavy lead health ...
