A brace device for the spinal support of a wearer. The brace device comprises a plurality of component parts, with each component part being moveable relative to at least one other component part, a movement sensing means for monitoring the movement of the wearer and/or the movement of one component parts, which is capable of generating output signals, a movement resisting means operable to prohibit, restrict and/or resist movement of the component parts, and a control means in communication with the movement sensing means and the movement resisting means programmed to interpret and/or analyze the output signals generated by the movement sensing means within predetermined parameters and/or criteria. Movement resisting means are activated, deactivated or dynamically controlled in response to signals received from the control means.
