Hi all.. My mom is a heart patient and she is suffering from foot drop after the stroke happened 2 months ago. She is not able to raise her front part of foot and possesses walking difficulties. When I have searched for some devices that would help her, I have found a product of Spark Innovations named GEMS They have mentioned that it is a device for the rehabilitation of patients suffering from after effects of stroke. Does anyone here know about this product? What is the main purpose of this device? Does it can help my mom in any way? Please reply me as soon as possible.
