摘要:

This article is the fifth in the series which discusses the impact of technology in the various specialist fields of modern medicine. Previous articles from the Presidents or representatives of the Royal Colleges of Psychiatrists, Surgeons, General Practitioners and Physicians were published in the May, July and September issues (1980) of the Journal.

摘要:

The relationship between the movement of the centre of foot pressure in the anterio-posterior plane and the rotation which occurs in the same plane at the level of the ankles, hips and shoulders during postural sway was examined in a group of normal human subjects. Expressed as three frequency-dependent functions this relationship consists of both relative magnitude and phase components. The magnitude component indicates that the pressure centre was most sensitive to ankle rotation, less to hip and least sensitive to rotation at the level of the shoulders. The sensitivity of the pressure centre was also a function of the frequency of the rotations and this is evidenced by the presence of several resonant peaks in the relationship. It is suggested that these could be due to body inertia and transmission delays. The resonant peaks became more prominent when the subjects stood with eyes closed. The growth of resonant peaks is taken as a sign of reduced postural stability and on this basis it is argued that a distinction should probably be made between the concepts of the stability and the steadiness of stance.

摘要:

An Intel 8080 microprocessor is used to control the running, and also analyse the results of a clinical test, the electrooculogram. The processor provides a moving stimulus using a strip of thirty-two light emitting diodes. From electrodes attached medial and lateral to the eyes, the sinusoidal signals generated by the stimulated lateral eye movements are monitored, digitised by the processor and the peak values stored for subsequent analysis. Results are plotted both numerically and graphically each minute of the test on a standard teletype. Throughout the test, systems faults are recognised and appropriate error messages produced. The test is automatically terminated and results calculated when sufficient data has been collected. The development of this system and the advantages of a microprocessor in this application are discussed.

摘要:

Services and aids for the handicapped are controlled by the local health authorities in Sweden and supervised by special mixed boards of politicians and experts. The organisation of the system is described in this paper, in addition to the role and functions of the Handkappinstitut. This is a central co-ordinating body for research development, testing and supplying information within the area of rehabilitation.

摘要:

The performance of instruments for measuring peak expiratory flow have been investigated. This evaluation was carried out with two designs of spirometer, two types of pneumotachograph and three versions of the Wright peak flow meter. The appropriate flow profiles were generated by means of a special type of flow calibrator. The errors produced by the instruments varied from zero to about 26%.
