OmoTrain S provides secure support for the shoulder joint and strongly promotes mobility in order to restore function. During each movement, the compression knit and a removable massage pad with frictional nubs (Delta pad) massage the soft tissue, thereby relieving pain and activating the musculature that stabilizes the joint. Simply slip it on using the healthy arm, pull over the head and arm, and secure in place with the Velcro fastening. Thanks to its direct strap system, the support participates in every movement and is easy to put on and take off. It is therefore particularly suitable for use in pain therapy, for immediate care for injuries and for protection against further injuries both in everyday activities and in sport. It provides intermittent compression to the shoulder which increases circulation, relieves pain and swelling, improves joint perception and activates the joint-stabilizing muscles.
