The document discusses rehabilitation of fingertip injuries through a process of desensitization. It involves three phases: 1) wound management through cleaning, drying, edema control and splinting, 2) range of motion exercises starting at 3 weeks, and 3) desensitization treatment to reduce hypersensitivity and encourage functional use starting around 6 weeks. The desensitization process uses repetitive physical stimuli of increasing intensity applied multiple times daily to gradually increase tolerance and return sensibility.
