Abstract: A support for the trunk or a limb or joint of a human or animal comprises a first band having first and second end portions with respective fasteners which can be fastened together to fix the band in a loop around the trunk or a limb or joint and at least one pad located inwardly of the first band for engaging a surface portion of the trunk or a limb or joint. The second band has a portion located inwardly of the first band and supports said at least one pad for movement independently of the first band when the first band is fixed to apply pressure to said surface portion. An adjustment means is connected to the second band and extends from an inner side to an outer side of the first band to allow operation outwardly of the first band when the first band is fixed for adjusting the position of said at least one pad.

Abstract: This invention provides neck traction devices wherein a resilient folded biasing body provides a traction force between a shoulder contacting side of the fold and paired head contacting regions. In use, a neck traction is developed when the folded device is applied to a patient with the respective shoulder and head regions contacting the patient's shoulder and head.

Abstract: A neck traction device comprising at least one head contact member and biasing means connected to the at least one head contact member, wherein, the biasing means comprises a resilient material that, when in use, provides a traction force on the user's neck via the at least one head contact member.

Abstract: Pulses of optical radiation are counted by a pulse counter in a way representative of its effects on tissue. An analog to digital converter digitizes detected optical radiation pulses and an integrator integrates the digitally detected pluses. The integrator has a time constant characteristic sufficient to combine digitally detected pluses that are close enough together so that they are effectively one pulse with respect to tissue exposure limits. The integrator can be programmable to a particular time constant based on a thermal confinement duration of human tissue and wavelength of laser pulses. A counter circuit counts pulses, and a display displays the counted pulses. A capture circuit enables counting the number of pulses occurring within a capture duration by the counter circuit. The analog to digital converter can be configured to a sensitivity.
