Mountain Bluebird Amputee

A Natural Occurrence of Foster Parenting by a Female Mountain Bluebird

In recent years, much attention has been devoted to the question of altruism in birds (e.g. Trivets 1971; Power 1975, 1981; Pinkowski 1978a; Pierotti 1980; Ligon 1983). In a study of potential altruism in Mountain Bluebirds (Sialia currucoides) in Montana, Power (1975) found that after removal of 13 female "consorts," 2 were subsequently replaced, with 1 of these females helping the male raise ...

Sprint Start Kinetics of Amputee and Non-Amputee Sprinters

The purpose of this study was to explore the relationship between the forces applied to the starting blocks and the start performances (SPs) of amputee sprinters (ASs) and non-amputee sprinters (NASs). SPs of 154 male and female NASs (100-m personal records [PRs], 9.58-14.00 s) and 7 male ASs (3 unilateral above knee, 3 unilateral below knee, 1 bilateral below knee; 100 m PRs, 11.70-12.70 s) wi...

The geriatric amputee.

1 Chief, Orthopaedic Service, Veterans Administration Center, Wilshire and Sawtelle Blvds., Los Angeles, Calif. 90073. The geriatric amputee not infrequently suffers from debilitating diseases other than the one which caused his amputation. These affect his prognosis for life, for retention of his other leg, his ability to use a prosthesis, the performance of activities of daily living, his par...

Lower limb amputee survival.

A total of 1710 primary amputees have been studied over a 25 year period and their survival time has been calculated. These were all consecutive primary lower limb amputees admitted to the Dundee Limb Fitting Centre during the period 1965-1989. Overall, the median survival was 4 yr 9 mth for the below-knee amputee (1019 patients) and 4 yr 3 mth for the above-knee amputee (586 patients). The vas...
