Massagers are now increasingly becoming popular with teenage students and young adults, especially women office workers. These light, compact units developed recently in Japan, for softening up stiff shoulders and the lower back can be bought for less than US $90. Omron Corp with its Elepuls series has captured 60 per cent of the domestic market. The model has provisions for shifting between sharp stimulus to milder sensations. Omron's top seller is the HV-F123, featuring five pre-programmed modes for massaging shoulders, back, arms and legs, joints and the soles of feet. A liquid-crystal display panel shows the pressure level and frequency of massage stimuli.
