A motion control apparatus for a hospital bed relates to a hospital bed provided with a plurality of wheel modules. An axial shaft passes through two wheel modules and moves together with the wheel modules. Three pedals capable of swinging upwardly and downwardly are pivotally disposed on the chassis in parallel. Two sides of the middle pedal lean on the pedals on two sides. Driving components are fixedly disposed in opposite directions on the axial shaft corresponding to the pedals on the two sides. A coupler is disposed between each driving component and pedal. When one of the two pedals on the two sides is stepped on downwardly, the axial shaft is driven to turn and results in the breaking of the wheel modules or where at least one wheel module cannot change direction thereof. When the middle pedal is stepped on downwardly, the other pedals gathered together swing downwardly at the same time, while the pedal that is originally stepped upon downwardly swings upwardly, and then the pedals on the two sides come to lean on the middle pedal at the same time and stop, resulting in the disabling of the breaking or orientation. Thus, the operation is more straightforward and conforms to common operation habits, and the user does not need to use his shoe to hook the pedal in order to control the operation.
