An exercise assembly structured to direct the foot-ankle-leg, knee, etc. Also provided are methods for using such compositions in the diagnosis or treatment of CNS disorders such as Alzheimer’s disease. Each light source is oriented relative to its associated reflector such that the axis of the beam of light hits the reflector off-center to generate a plane of light that is dispersed less than 360 degrees. The instrument can also comprise one or more sensing probes and a communication port to facilitate data collection, transfer and analysis. An optical antenna is coupled to the cross-section formed by the distal end of the multimode optical fiber, for example, via an auxiliary lens to provide increase in output radiation beam divergence. 1 to 30 parts by weight of a curing agent capable of generating a free radical upon heating, and a process for producing a wiring-connected board by using the wiring-connecting material.
