Udar mózgu jest jedną z najpoważniejszych chorób stanowiących trzecią z najczęstszych przyczyn zgonów. W oparciu o badania siły ścisku dłoni z wykorzystaniem dynamometru elektronicznego firmy Vernier, podjęto próbę oceny zdolności siłowych dłoni pacjentów po przebytym udarze, a także przedstawiono znaczenie wdrażania nowoczesnych technologii, pomocnych przy analizach postępów rehabilitacji. To właśnie w dziedzinie techniki można upatrywać największego potencjału rozwojowego w metodach leczenia udarowców na nadchodzące lata.

Stroke is one of the most severe diseases which is the third of the most frequent cause leading to death. Based on studies on hand grip force using electronic dynamometer made by Vernier company, some attempts were taken to assess hand force capability of patients with neurological disorders. Also the importance of the implementation of modern technologies to assist in the analysis of the progress of rehabilitation was presented. The field of technology has the biggest potential for development in methods for treating patients after stoke in the coming years.

The aim of the study was to develop a theoretical indicator of upper limb musculoskeletal load based on repetitive task parameters. As such the dimensionless parameter, Integrated Cycle Load (ICL) was accepted. It expresses upper limb load which occurs during 1 cycle. The indicator is based on a model of a repetitive task, which consists of a model of the upper limb, a model of basic types of upper limb forces and a model of parameters of a repetitive task such as length of the cycle, length of periods of the cycle and external force exerted during each of the periods of the cycle. Calculations of the ICL parameter were performed for 12 different variants of external load characterized by different values of repetitive task parameters. A comparison of ICL, which expresses external load with a physiological indicator of upper limb load, is presented in Part 2 of the paper.

The aim of the study was to compare the theoretical indicator of upper limb load with the physiological indicator of musculoskeletal load, which is present while performing a repetitive task (a normalized electromyography [EMG] amplitude recorded from the muscles of the upper limb involved in the performed task). In an experimental study of a repetitive task, the EMG signal from 5 main muscles of the shoulder girdle, arm and forearm was registered: extensor carpi radialis longus, flexor carpi ulnaris, deltoideus anterior, biceps brachii caput breve and trapezius descendent. The results of the study showed a strong correlation between the theoretical indicator (Integrated Cycle Load) and the physiological indicator (root mean square of a normalized EMG amplitude from the 5 muscles). This proves that the developed theoretical indicator can be accepted as an indicator of upper limb musculoskeletal load during a work task.
