Different kinds of services and informal support in the daily life activities in a community-based elderly population.

As part of the well-known population study of 70-year olds in Gothenburg, 1239 persons at the age of 70 were invited to participate in an extensive investigation and Inter-Vention program of the Elderly in Gothenburg (IVEG). The probands were examined at the ages of 70, 73 and 76 years. The purpose of this study is to describe different kinds of services and informal support in the daily life activities among three large groups of people in their seventies.

Training can improve muscle strength and endurance in 78- to 84-yr-old men.

Nine men, 78-84 yr of age, participated in a dynamometer training program 2-3 times/wk, totaling 25 sessions, using voluntary maximal isometric, concentric, and eccentric right knee-extension actions (30 and 180 degrees/s). Measurements of muscle strength with a Kin-Com dynamometer and simultaneous electromyograms (EMG) were performed of both sides before and after the training period. Muscle biopsies were taken from the right vastus lateralis muscle.

Compensatory muscle fiber hypertrophy in elderly men.

Muscle strength and muscle morphology have been studied three times during a period of 11 yr in nine elderly men. On the last occasion the average age was 80.4 (range 79-82) yr.

[The Svalebo program--successful rehabilitation of hip fracture patients].

The aim of the Svalebo programme is improved rehabilitation and increased home discharge of patients with hip fractures, and a better use of health care resources. The programme includes contact with the hip fracture patients at the orthopaedic clinic, a rehab programme on an outpatient basis 1-3 days a week. As a result of the programme, the role of the day hospital has become clearer and the flow of patients through the orthopaedic department has increased, the mean duration of hospitalisation having decreased by 30 per cent.

Muscle adaptive changes in post-polio subjects.

Nineteen post-polio subjects (9 men and 10 women) aged 41-65 years were studied by means of muscle strength measurements (Cybex) of knee extension and muscle biopsies of the vastus lateralis for morphometric, histopathological and enzymatic analyses. Data from a reference group of 10 male subjects, age 42-51 years, are also given. Fourteen of the post-polio subjects had experienced a post-polio syndrome-like drop in function.
