Abstract: A method for self-administering physical therapy is disclosed. The method may comprise inserting a massage element (e.g., a massage ball) into a receiving space of a sling. Thereafter, the user may use the sling to position the massage element adjacent to a portion of a body (e.g., a dorsal or distal portion of the user's body) that would be difficult to reach or access without the use of the sling.

Abstract: A massaging roller may comprise a first cylinder and a second cylinder. The roller may be arranged in a first or second configuration depending on which end of the first cylinder is connected to which end of the second cylinder. In the first configuration, an interior space between opposing ends of the first and second cylinders may form a first cavity of a first size. Conversely, in the second configuration, an interior space between opposing ends of the first and second cylinders may form a second cavity of a second, smaller size. This may enable the roller to receive and secure therewithin vibration elements of different sizes. That is, vibration elements of different sizes may be used alone for therapeutic benefit or may be installed within one of the first cavity or the second cavity to impart vibration to the roller.
