A postural feedback device for assisting user awareness of joint, muscle, or body part alignment is disclosed. Embodiments include at least one linear or rotary sensing unit comfortably and discretely adhered to the user's skin, a hardwire connection cable or wireless transmission sending unit, and an electronic console for interpretation of information from the sensing unit and biofeedback of said information via stimulus to the user. The postural feedback device may comprise multiple sensing units of various sizes simultaneously allowing for variations in application, user size, and size of body part being monitored. The electronic console may provide biofeedback to the user in the form of tactile, auditory, visual, or other stimuli, aiding the user in awareness of postural alignment or instruction of a desired anatomical movement. The sensing unit may be constructed allowing a low-profile, comfortable fit, allowing the device to be worn discreetly underneath clothing.
