This invention relates to massage apparatus and a method of its use for massage of the human body, the massage apparatus comprising a frame supporting opposingly-located first and second massage tools mounted thereon to define between them a massage gap, wherein a body portion is receivable for massaging, and gap-adjusting means, whereby the gap is adjustable while the apparatus is in use, for the massage tools in use to exert therapeutically effective force substantially continuously on a massage-receiving body portion received in the gap. The massage tools are interchangeable with massage tools of other shapes designed to provide different therapeutic effects. The frame is open- and closeable by operating the gap adjusting means to accommodate limbs of different sizes.
