83-year-old female resident ("Resident 4") - no additional fall mitigation strategies. In the early morning hours, an unwitnessed fall occurred while wearing the smartbelt in her room. The smartbelt detected an irrecoverable serious hip-impacting fall motion, deployed airbags and sent alerts of the fall. Nursing staff reported no injury following physical inspection. Post-hoc analysis of motion data captured by the smartbelt indicated a distinct pattern of gait with increasing postural sway prior to the fall, suggesting that the resident attempted to walk from her bed across the room prior to losing her balance and falling onto her side.
