After the actual operation, I found that there are many details on the wheelchair design that can be used. If you do n’t know it, you wo n’t use it. Most of the hospitals are barrier-free facilities and will not encounter too many problems.Most people use word-of-mouth or imitation. After this training, I discovered that the basic concept of choosing a wheelchair is very important at the beginning. Choosing a suitable wheelchair can also reduce the burden on the caregiver.
