The new machine for concentric-concentric activation of upper limb and trunk muscles has finally arrived at Scipion from the USA. Hydraulic resistance uniform in all directions, combined with specific exercise protocols developed at our institution, enable us to:

• Achieve very early postoperative activation of the shoulder girdle muscles.
• Activate back muscles in a protective position postoperatively and in cases of complex spinal disorders.
• Activate multiple muscle fibers simultaneously compared to isotonic exercises.
• Reduce or completely eliminate the risk of injury due to the exclusion of the eccentric component of movement.
• Minimize muscle inflammation.
• Shorten training time.
• Shorten rehabilitation time after injuries or surgical procedures.
