The new ex-o-wrist Pro Pak consists of 3 ex-o-wrists with preset tensions. That’s right no more tension adjustment. Use the black, minimally tensioned ex-o-wrist for a weaker patient just beginning rehab. Use the white ex-o-wrist, medium tensioned for a patient that is progressing. And use the yellow ex-o-wrist, maximum tensioned for the rehab patient to build up strength, coordination, flexibility and endurance. Preset tension eliminates errors and patient interference. Now the practitioner can be confident about their patients progress and health.
