Problem

Low Patient Adherence: Many patients lack motivation and consistency during home rehabilitation, leading to incomplete or improper training.
Lack of Personalized Feedback: Patients struggle to determine whether their rehabilitation movements are correct or meeting recovery goals, affecting outcomes and safety.
Limited Interaction Between Doctors and Patients: Doctors face challenges in monitoring patient progress or adjusting plans in real-time, and rehabilitation guidance often lacks continuity.
Fear of Re-injury: Many patients feel insecure during rehabilitation, worrying that improper movements could lead to re-injury, further reducing their willingness and efficiency in training.

Foldable wireless charger

The foldable wireless charger can charge five sensors at the same time. However, considering the different power consumption of each sensor, users do not need to charge multiple sensors simultaneously. Therefore, to save space, users can fold the wireless charger to facilitate charging the product.
