Abstract: A force transducer is disclosed, which is arranged in such a way that, when a force is applied to the force transducer, two output signals from the force transducer are generated, which output signals are representative of the force components in a first plane and in a second plane perpendicular to the first plane, respectively, whereas force components in a third plane perpendicular to the first plane and the second plane do not affect the output signals from the force transducer. Furthermore, a measuring device is disclosed, comprising a handle comprising such a force transducer and a base unit, to which the handle is attached. Even further, a system for measuring muscle stiffness is disclosed, comprising a measuring unit and a processing unit, the measuring unit comprising such a measuring device.

Abstract: A system, an apparatus, and a method for measuring muscle stiffness in a predetermined joint of an individual are provided. The system and apparatus comprises a measuring unit and a processing unit. The measuring unit is configured to be applied to a body segment of the predetermined joint. The processing unit is configured to: receive a plurality of data sets from the at least one measurement device, analyze the plurality of data sets for one or more indications of an elicited stretch reflex, and calculate a muscle stiffness score. The muscle stiffness score is based on at least a difference between a first stiffness and a second stiffness. The first stiffness is determined from the first subset, and the second stiffness is determined from the second subset.
