摘要:

The medical records of 385 amputees were studied to determine if the trends of high occurrence of death and second amputation for patients with vascular disease still exist and if so, to what degree. All the subjects experienced their first amputation between Jan. 1, 1982, and Dec. 31, 1987. Their patient charts were followed for a five- to 10-year period, as applicable, from the date of first amputation until the last entry prior to Dec. 31,1992.Multiple amputations occurred in 59 percent of the patients. Thirty-five percent of the subjects underwent a revision to the original amputation within an average of 6.5 months. Contralateral amputation was performed on 30.9 percent of the subjects. Contralateral amputation occurred an average of 24.9 months following the first amputation. Eighteen percent of all patients studied died within the time frame of this study. The average time between contralateral amputation and death was 18 months

摘要:

Decubitus ulcers can lead to very serious medical consequences for nonambulatory people who have impaired sensation. Associated medical treatment can be extremely expensive. Factors contributing to the formation of ulcers are discussed. Seating orthosis design characteristics that can reduce ulcer-generating factors are presented. Particular attention is given to design features and custom fabrication techniques related to redistributing pressure away from at-risk locations and to minimizing shear.

摘要:

A survey of literature was conducted on hand grip strength and grip strength with prosthetic prehensors of children 2 to 4 years old. The survey's purpose was to set grip strength requirements for a pediatric body-powered prosthetic hand. The survey included studies of grip strength in normal hands, grip provided by children's voluntary opening and voluntary closing prehensors and structural factors that enhance grip, such as friction, resilience and prehensor geometry. After comparing findings from studies in the literature survey, minimum grip force levels of 2 lbs. for 2- year-olds and 4 lbs. for 3- and 4-yearolds were incorporated into hand design specifications. Additional grip force, beyond the minimum, is considered highly desirable. Incorporation of grip-enhancement features into prehensor structures also is recommended.

摘要:

Survey research involves looking at the relationships between sociological and psychological variables and relies on various methods of data collection, including in-person and telephone interviews and questionnaires that are mailed or used with an interview or group administration. Each method has the potential for error or inaccuracy. This article introduces various types of survey research while focusing on questionnaire development and use. Recognizing and accounting for survey measurement error when using questionnaires also is discussed.
