ABSTRACT:
A transducer head for a muscle testing apparatus has at least two and preferably three pressure test pads situated in three different test planes whereby different directional forces can be applied to the transducer head without the need to adjust its angular orientation. The test pads are mounted on anti-shear arms within the transducer housing so that the forces on the test pads can be transmitted to transducer elements within the housing about a remote shear arm pivot axis. In the preferred embodiment, only two transducer elements are required, one for two opposing test pads, and one for a front test pad in a test plane perpendicular to the test planes for the two opposed test pads. An optional pull device, which projects from the transducer head housing, is attached to one of the anti-shear arms such that the transducer element associated wih that shear arm is responsive to a pulling force on the pull device as well as a pushing force on the associated pressure test pad.
