Post injuries our muscles often become weak and need additional attention. Vissco Pro now launches the 'Flexiball' or hand exerciser (P.C.No.6601). It can be used by Physiotherapists or Patients themselves for strengthening of muscles, sports training or overall rehabilitation of the hand as it helps improve opposition, flexion, adduction of fingers and precision. Being more flexible and made up of a softer gel material, this ball allows more movement than conventional exerciser balls. They are available in soft, medium and hard variations.
