The invention relates to the technical field of motor function analysis, in particular to a big data-based balance index display model for motor function analysis. An overall stability index of each player of a whole team is tested by using a Biodex isokinetic muscle strength assessment training system; a standard value M and a standard deviation SD of an overall stability index of the whole team are calculated; balance energy bar numerical values are calculated according to a formula; and different colors are displayed according to a numerical range. By building the big data-based balance index display model for the motor function analysis, balance indexes are directly converted to be in the form of energy bar scores which are of practical reference significance for a match and are displayed through the different colors, so that the balance indexes can be viewed more directly, players can better locate the positions of their balance abilities in the whole team, competitive mentality of the players can be aroused, the players can perform training for constraint indexes more actively, and the overall strength of the team can be improved.
