An assembly of electrically-powered devices designed for professional use to apply multiple different energies (e.g., light-energy, ultrasound, radio-frequency electrical stimulation, electrotherapy) either alone or in sequence, but not simultaneously, to noninvasively treat/prevent a variety of soft-tissue, neuromuscular, and musculoskeletal injuries/disorders (e.g., joint pain/inflammation, stiffness, soft tissue injuries, muscle atrophy); it may in addition be used for aesthetic skin/body contouring (e.g., minimize cellulite, loose or wrinkled skin). It consists of a multi-modality control unit/generator, and dedicated applicators for the transcutaneous delivery of energy.
