A robotic muscular therapy system, and method of use, for applying repeated amounts of concentrated pressure to targeted muscles one-at-a-time to lengthen even deeply positioned muscle tissue layer by layer and thereby reduce limitations on joint extension and flexibility as well as eliminate pain caused by excess muscle contraction. The system comprises a beveled treatment probe designed to concentrate pressure without breaking the skin of an average patient, a probe column assembly for fine X, Y, and Z probe movement over a patient, and a plurality of interchangeable column assembly supports for coarse X, Y, and Z probe movement. Patient safety limitations include a torque-limited and current-limited motor with a slip clutch, a probe which withdraws from its treatment position when a patient grabs it or a pre-set maximum tissue pressure is encountered, and a swivel fitting which allows the probe to give when a patient sneezes and allows patients to easily push the probe away upon demand. The system may optionally have an X-Y positionable patient support; automated control means probe movement; a computer learn mode for creating individualized treatment routines; patient movement sensors; and probe sensors for patient progress data collection. Applications can include, but are not limited to, elimination of acute and chronic of pain; treatment of conditions resulting from accidents and injury; pre-surgery conditions involving muscle spasm; post-surgery recovery, reduction of scar tissue, and restoration of flexibility; reduction of stress and tension; improved sports performance; treatment of conditions involving restricted physical movement; and postural improvement.

An apparatus for auscultation and percussion of a human or animal body has a stethoscope with a diaphragm on one side of a head thereof, and a percussion mechanism positioned in the head for selectively producing a percussion against the body such that a sound from the percussion mechanism is passed through a tube connected to the head. The percussion mechanism includes a cylinder positioned within the head, a piston slidably positioned within the cylinder, and an activator lever connected to the piston for moving the piston between a first position adjacent to an impact element and a second position away from the impact element.
