hi, thank-you for providing the brief history of you. a thorough neuromuscular assessment is advised. As the neck and back injuries are common after a fall from a hill and shouldn t be ignored. Also to understand that you may need an MRI of the cervical and lumbar spine to check the extent of the soft tissue Injury. Apparently I think you have not injured any nerve so your hand function and elg function are normal. Also, post removal of the brace you may need to undergo physical therapy for your neck. Avoid undergoing chiropract therapy for time being as the neck is too weak to handle the therapy. physical therapy will help you strengthen the muscles slow and gradually. Once the therapist finds the strength in the muscle is regaining he may ask you to undergo a thorough clinical neuromuscular assessment which he will perform. Also, until your muscle becomes stronger try to avoid heavy physical exertion. avoid gym and sports too. In my clinical practice I have seen cases with falls and injuring both the cervical and lumbar spine at one time. The recovery is slow but with physical therapy the patients recover faster the muscle property is maintained with physical therapy. Regards Jay Indravadan Patel
