Table 1. Activity of the muscles of the tested and the not tested leg/side in the standardized and the original version of the Bunkie Test. leg/side muscle mean MPF/time (sd) standardized test mean MPF/time (sd) original test not tested es -0.18 (0.32) 0.17 (0.82) tested es 0.16 (0.95) -0.12 (0.38) not tested gm -0.40 (0.55) -0.52 (0.90) tested gm -0.44 (0.82) -0.21 (0.56) not tested bf 0.01 (1.62) -0.27 (0.63) tested bf -0.91 (1.08) -0.59 (0.30) not tested ga -0.50 (1.21) -0.23 (0.69) tested ga -0.49 (1.00) -0.16 (0.40) MPF, median power frequency; sd, standard deviation; es, M.erector spinae; gm, M.gluteus maximus; bf, M.biceps femoris; ga, M.gastrocnemius. Muscle activity is shown as median power frequency (MPF) over time regression slope.
