The reliability and validity of isokinetic measurement of plantar flexion endurance has been studied by a method previously described by us which utilizes simultaneous measurements of mechanical contractional work (CW) and integrated electromyogram (iEMG). The reliability was gauged by test/re-test with a two year's interval; while validity was assessed by myoelectric power spectrum analyses. The ...
The aim of the study was to quantify the activity as recorded by electromyography during ergometer cycling in eleven different muscles of the lower extremity. Eleven healthy subjects rode in twelve different ways at different work-load, pedalling rate, saddle height and pedal foot position. Vastus medialis and lateralis, gastrocnemius medialis and lateralis and the soleus muscle were the most acti ...
A radiographical study of 20 loaded knees of healthy subjects and a knee dissection study of 20 specimens were performed in order to present a two-dimensional patello-femoral joint biomechanical model. A constant knee-extending moment gave 25-40% lower force magnitudes in the patellar tendon than in the quadriceps tendon if the knee was flexed to 60-120 deg. The magnitude of the patello-femoral jo ...
In order to evaluate methods to prevent pressure sores the effect of massage on the local skin blood flow was studied in normal skin and in skin with discolouration (red or reddish blue). In this study massage is defined as small circular movements with the fingertips using liniment. The cutaneous blood flow was measured with a laser Doppler flowmeter. To study the long term effect of massage on n ...
Thirty-six severely mobility-disabled subjects aged 24-52 years using a wheelchair and in need of daily assistance and 36 non-handicapped, matched control-subjects were interviewed. They were asked to rank 30 different abilities involving physical and mental functions, interpersonal and social relationships, and to rate their overall quality of life (QOL) on a 0-10 point scale. Among the severely ...
The aim of this study was to assess the cognitive skills and visuo-motor performances of patients with type-2 diabetes. An ADL questionnaire, neurophysiological EEG recordings and a comprehensive battery of neuropsychological tests were administered to 33 type-2 diabetics and to 33 matched controls. Neither neuropsychological nor neurophysiological EEG findings differentiated type-2 diabetics as a ...
