Indications: For patients with tense hand muscles who are unable to actively open their hands. Has your hand been clenched in a fist since your injury? Stretching and massaging it every day isn't working? Studies show that to effectively reduce spasticity caused by tension, you need to stretch for 6-8 hours a day. iOpen Stretch is a dynamic stretching orthosis that can help patients stretch their hands for over 10 hours a day. Lightweight, simple, easy to operate, and can be worn by the patient after training. It can be used in the home and is not limited to the treatment setting.
