This passive-exercise device, often marketed with the prefix “Sun Ancon,” typically consists of a padded board oscillating from side to side. Users lie on the board, with their ankles resting on a padded bolster, allowing the machine to gently rock their body. This rhythmic movement is intended to promote relaxation, improve circulation, and enhance lymphatic drainage.
Proponents suggest this form of passive exercise can provide a range of health benefits, including stress reduction, pain relief, and increased energy levels. They often point to the device’s potential to stimulate specific acupressure points, mimicking the effects of a massage. Historically, similar oscillation devices have been utilized in therapeutic settings for rehabilitation purposes, albeit with different design and functionality. The contemporary iteration often draws upon principles of traditional Chinese medicine, though scientific evidence supporting its effectiveness for many of the advertised health claims remains limited.
