Abstract:Objective To design a device with plantar flexion, dorsi flextion, and counting functions for ankle joint rehabilitation training, and produce a prototype.Methods Based on market available magnetic induction counters, wooden boards, springs, tapes, and other items, we attempted to create a prototype of a rehabilitation training counter according to the design.Results We have successfully produced a prototype and conducted a summary discussion. The prototype has ankle joint rehabilitation training and counting functions.Conclusion This device can be used for ankle joint rehabilitation training and has a counting function, and it also provides a new idea for the development and design of similar products.
