A data collection system comprising: a patient support a support member attached to the patient support; a data collection system controller attached to the support member, the data collection system controller further comprising: a housing (12, 14) comprising: a user facing section and a patient support facing section defining a hole, a first side of the patient support facing section being adjacent to the user facing section; a first input device provided on the user facing section, the first input device having a substantial planar section; a second input device comprising: a knob comprising a third input device, a rotatable shaft extending through the hole and partially disposed within the knob; and an attachment device adjacent a second side of the patient support facing section opposite the first side, and engaging the support member of the patient support, the user facing section and the patient support facing section disposed at an angle relative to each other, wherein the patient support facing section and the rotatable shaft are tilted towards the patient support in order to provide a reduction in strain to a user's hand when controlling the second input device; and the user facing section and the planar section of the first input device are tilted away from the patient support in order to prominently display the first input device to the user such that it is not obscured. a patient support a support member attached to the patient support;
