Spinal\nreflex and voluntary supraspinal activations were measured and analyzed in three different\nlatencies at both methods. Total of 9 participants (6 women, 3 men) between the ages of 20 and\n40 were recruited to the study. The study consisted of two separate measurements. In addition,\nEMG raw data was measured during dynamic balance test. The dynamic balance test consisted\nof at least 16-22 randomized anterior-posterior direction perturbations induced by motorized\nbalance platform. Same protocol of platform movement was used at dynamic balance tests and\nmeasurements with both H-reflex and TMS stimulations. Swim cap was used to place and\nstabilize the TMS coil on the head. Stimulation latencies were measured and calculated by\nindividual H-reflex latency. Same latencies were used in both H-reflex and TMS methods: 0-,\nMLR- (~80ms) and MLR+120ms (~200ms) from the start of the platform movement.\nRepeatability of two separate individual measurements in H-reflex to anterior direction showed\nexcellent (ICC>0,81) at 0-, good (ICC=0,61 \u2013 0,81) at MLR and moderate (ICC=0,41\u20130,60) at\nMLR+120 latency. In H-reflex measurements to posterior direction showed good (ICC=0,61 \u2013\n0,81) to excellent correlation (ICC>0,81). Repeatability of MEP latencies to anterior direction\nshowed good (ICC=0,61\u20130,81) correlation at MLR+120 latency and excellent correlation\n(ICC>0,81) at 0- latency. MEP measurements to posterior direction at 0- and MLR+120 showed\ngood (ICC=0,61\u20130,81) correlations and latency of MLR excellent (ICC>0,81) correlation.\nThere was significant difference between H-reflex latencies of 0 and MLR (p<0,001) and MLRMLR+120ms (p<0,001) to anterior direction. H-reflex to posterior direction showed significant\ndifference between 0 and MLR latencies (p<0,01). A significant difference to posterior\ndirection was observed between 0 and MLR (p<0,01) and between MLR and MLR+120ms\n(p<0,001). The results of this study addressed the reliability and repeatability of both H-reflex\nand TMS methods during dynamic weight-bearing conditions. Further, these results\ndemonstrated the potential usability of forementioned methods to depict both spinal and\nsupraspinal regulated activity during fast anterior posterior directioned dynamic balance\nperturbation measurements.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-06-30T08:52:57Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-06-30T08:52:57Z (GMT).
