This intervention consists of standard clinical postoperative care and discharge education, encompassing wound management, follow-up appointments, and generic neck activity guidelines. Prior to discharge or upon clinical stability, participants undergo a one-time, face-to-face training session with research staff featuring practical exercise demonstrations and behavioral precautions, and are provided with identical instructional video materials for home reference.

Quantitative measures tracking patient engagement with the digital platform, defined by the digital questionnaire completion rates, loss to follow-up rates, cumulative exercise mini-program check-in days, and consecutive check-in days.

Safety endpoints mapping the frequency and severity of post-surgical complications (e.g., wound bleeding/hematoma, incision dehiscence, surgical site infection) or any adverse events deemed by the investigator to be potentially related to the physical exercise regimen (e.g., severe motion-induced pain exacerbation, acute dizziness).

Objective clinical measurement of neck mobility, quantifying the exact degrees of cervical movement achieved during forward flexion, backward extension, left/right lateral flexion, and left/right rotation, assessed by a blinded investigator.
