W pracy opisano budowę dynamometru przeznaczonego do badań postępu procesu rehabilitacji. Dynamometr, dzięki radiowej transmisji danych pomiarowych do komputera, umożliwia rejestrację przebiegu ćwiczeń i wykonywanie analizy przebiegu rehabilitacji. Budowę dynamometru oparto na nowoczesnym mikrokontrolerze jednoukładowym ADuC845. Opracowano program w środowisku LabVIEW, który umożliwia analizę rejestrowanych danych.

The construction of the push-pull dynamometer dedicated for the investigation of the rehabilitation process is described in the paper. The application of the wireless data transmission between the dynamometer and computer allows users to record and make analysis of rehabilitation process. The dynamometer circuit is based on the ADuC845 microconverter. Application in LabVIEW was carried out for analysis of data from dynamometer.

An ergonomic assessment of the involvement of static muscular forces like back strength, grip strength and pinch strength in different occupations was made. A study was conducted on 45 normal adult males (15 subjects per group) which included video display terminal (VDT) operators, industrial workers and safety inspectors. Their maximum back strength, handgrip strength and pinch strength were measured with dynamometers. The observed values of back strength were significantly lower in VDT operators while significantly higher in safety inspectors and moderate in industrial workers. The values of grip strength and pinch strength of all sample groups were more or less similar. The findings clearly indicate that static muscular strength varies significantly in different occupations. Heavy static muscular load might lead to an accumulation of metabolic waste and toxins on the back resulting in lower back strength in VDT operators and industrial workers.
