Tissue treatment stick

1. A tissue treatment stick comprising:

a treatment section comprising a vibration motor; and

at least two handles,

wherein the treatment section is disposed between the two handles,

wherein the treatment section has at least two and at most three edges, the edges extending parallel to a longitudinal axis of the tissue treatment stick,

wherein the edges have an edge-forming cross-sectional radius of curvature smaller by at least a factor of 3 than any radius of curvature of two sections directly adjacent to the edge-forming cross-sectional radius,

wherein the vibration motor is configured to:

generate a directed oscillating movement of the treatment section, and

cause the treatment section to vibrate,

wherein a direction of the oscillating movement extends radially from a center point of the treatment section through the edges,

wherein a first edge of the edges is made of wood, and

wherein a second edge of the edges is made of a rubber-elastic material.

2. The tissue treatment stick according to claim 1 , wherein the edges comprise a third edge, and wherein the third edge comprises ribs.

3. The tissue treatment stick according to claim 1 , wherein at least one edge of the edges is removable.

4. The tissue treatment stick according to claim 1 , further comprising a sensor configured to detect a force applied to a connective tissue, a muscle, muscle fasciae or tendons to be treated via the treatment section by the two handles.
