"... The greater the distraction frequency, the better the outcome..."
Dr. G.A. Ilizarov
The Automator performs precise micro-distractions up to once each minute rather than every six hours as is typical with manual systems. A study performed at Texas Scottish Rite Hospital (Makarov, 1999) demonstrated in a goat model that muscle tissue was preserved far better during automated (more continuous) lengthening than with 1/4mm increment distraction.
The University of Oslo (Steen, 1999) documented forces generated during distraction in a clinical study using patients having bilateral lengthenings. A comparison of Automated-high frequency distraction on one limb to manual distraction on the other limb revealed that continuous distraction substantially reduced the forces generated during lengthening. Furthermore, the Norwegian group noted a correleation between forces generated during distraction and pain experienced by patients. Patients with both legs lengthened felt less pain on limbs lengthened automatically using the Automator.
