Patients diagnosed with multiple sclerosis ability voluntary activate quadriceps femoris muscle during isometric workload

In this research we made an attmept to assess men and women diagnozed with multiple sclerosis quadriceps femoris muscle power and muscle voluntary activation level depending on the time of the day. The purpose. To determine patients diagnosed with multiple sclerosis ability voluntary activate quadriceps femoris muscle during isometric workload. Aims 1. To assess men and women right and left legs involuntary muscle power during initial electrostimulation appliance. 2. To assess men and women right and left legs electrostimulation 100 Hz (involuntary) muscle power during 2 min. isometric workload. 3. To assess men and women right and left legs voluntary muscle activation level during 2 min. isometric workload. 4. To assess men and women right and left legs muscle maximal voluntary power during 2 min izometric workload. Research Methods. In this research took part Multiple Sclerosis Society of Kaunas District “OREMUS” patients. Research was performed in LAPE “Human Motorics Laboratory”. Men (n=6), women (n=6). Men age average in years 48,4±7,6, inch – 176,0±5,5, weight – 75,4±15,3, women age average. 47,2±6,8, inch – 167,5±4,5, weight – 70,2±11,6. The applied tests methods were isokinetic dynamometry (Biodex Medical System 3, New York), electrostimulation (twitch interpolation). Body fat, weight, thus other indexes were assesed by bioelektronical impedans analyses method with Body composition analyzer TBF-300“ (TANITA). Conclusions. This research dislosed, that men diagnosed with multiple scerosis indexes of involuntary muscle power during initial electrostimulation, involuntary muscle power, voluntary muscle activation level thus muscle maximal voluntary power during isometric workload are higher then women and are dependent of the time of the day. Men are able to activate quadriceps femoris muscle higher
