<p>The device is for applying pressure against body points, e.g. trigger points and/or painful points or areas. It comprises an oblong body (3) formed by an arm (4) provided with a ball-shaped body (6) at the arm free end and a shaft (5) which forms an angle with the arm. At the shaft free end is a support component (8) for ensuring pressure against the body point. Between the support component and the shaft a spring component (12) with inbuilt elasticity is arranged so that the pressure which the ball-type body exerts on the body part can be varied.</p> |
