In daily life, healthy listeners can usually easily complete the movement synchronization according to the rhythm of the sound, such as following the music and nodding in response according to the rhythm of the conversation. This reliance on auditory temporal cues highlights the cornerstone role of sound in shaping temporal perception. But for the hearing-impaired people, the visual channel is the core way for them to perceive the rhythm. Starting from the differences of synchronous audio-visual channel of healthy listeners, taking the visual rhythm processing of hearing impaired people as the core, combining the “functional compensation hypothesis” and “auditory scaffolding hypothesis”, we systematically summarize the behavioral performance and neural mechanism of visual rhythm processing of hearing impaired people under the condition of auditory deprivation. The study shows that the dynamic visual information processing ability is significantly enhanced, accompanied by the cross-modal reorganization of the auditory cortex; However, the absence of auditory scaffolding leads to the limited ability to resolve the complex time series structure. Future studies can integrate computational models and neural intervention techniques, explore the dynamic balance mechanism of audio-visual compensation, and further promote the theoretical improvement and practical application of cross-modal compensation mechanism. %K 听障人群， %K 视觉节奏加工， %K 背侧通路， %K 听觉脚手架假说
