A device for performing acupuncture on a patient using laser radiation as a device for producing laser radiation and a handpiece (1) which is connected thereto and which is brought into contact with the body of the patient in order to apply the laser radiation. The handpiece (1) has at least one light conducting fiber (4) which is connected to the device (7) for producing laser radiation and which is in contact with the body of the patient during the acupuncture and applies the laser radiation thereto.

A light therapy system utilizes an array of light emitting diodes which emit noncoherent light in a narrow bandwidth centered at a designated wave length. The diodes are mounted to project and focus their output on a dermal zone of a patient. A continuous or a pulsed voltage differential is utilized to energize the diodes. Higher voltage differential and peak current flow across the diodes is provided in pulsed operation than in continuous operation. With a designated wave length in the infra red bandwidth, a treatment regimen including a session of 5-10 minutes of continuous operation and a session of 5-10 minutes of pulsed operation once or twice per day has been effective in alleviating various musculoskeletal disorders. A similar treatment regimen utilizing diodes emitting light centered at the red light wave length has proven effective in the treatment of skin ulcers and delayed post operative wound healing.

A device for biostimulation of tissue is disclosed comprising an array of substantially monochromatic radiation sources of a plurality of wavelengths, preferably of at least three different wavelengths. The radiation sources are arranged within the array such that radiation of at least two different wavelengths passes directly or indirectly through a single point located within the treated tissue. The radiation sources are preferably laser diodes, superluminous diodes or similar light-emitting diodes that, while low-power radiation sources, can provide significant energy densities to a treatment area. A method of treatment of tissue comprising exposing the treated tissue to the above-described device is also disclosed. The device for biostimulation of tissue may be included within a system with a control panel, a power source, variable pulse frequency, variable pulse duration, a timer for timing the period of treatment, a device for measuring the conductivity of the treated tissue, a device for measuring the optical power emitted by the radiation sources and/or a device for detecting emissions from the radiation sources.

An improved transcutaneous electrical nerve stimulator (TENS) involving a microcurrent (typically 25 to 900 microamps) monophase D.C. carrier signal (typically 10,000 to 19,000 Hz, preferably 15,000 Hz) that is modulated on and off in time (typically at 0.3 Hz up to 10,000 Hz, preferably 9.125 Hz followed by 292 Hz) and further inverted about every second by reversing the polarity of the signal at the electrodes. Such a device has been found to be useful in alleviating pain very rapidly.
