Evaluation of a Novel Airbag Hip Protector in Older Adults
| Japan |
Older adults with conditions qualifying them for admission to a convalescent rehabilitation ward who are currently hospitalized in a medical facility or admitted to a geriatric healthcare facility.

Hip fracture incidence per fall will be observed among older adults wearing a novel hip protector currently under development, and its safety, fit, and acceptability will be evaluated. In addition, real-world patterns of use, rehabilitation implementation, and physical function will be comprehensively documented in routine clinical settings to generate foundational data for practical deployment of the device and to inform future interventional studies.

Incidence of fall-related hip fractures during the observation period (number of hip fractures per cumulative number of falls)
Evaluation period: During the observation period (for hospitalized participants, from initiation of wear to discharge; for nursing home residents, from initiation of wear to 3 months. In addition, if consent is obtained, assessments will be continued throughout the 6-month post-discharge follow-up period).
Fall incidence (number of falls per unit time; number of falls per 100 patient-months at each study site)
Evaluation period: During the observation period (for hospitalized participants, from initiation of wear to discharge; for nursing home residents, from initiation of wear to 3 months. In addition, if consent is obtained, assessments will be continued throughout the 6-month post-discharge follow-up period).
Physical function assessments (grip strength, Hasegawa Dementia Scale, Timed Up and Go test)
Evaluation period: At initiation of wear; every 2 weeks during wear; at discharge (or 3 months after initiation of wear); and at outpatient follow-up visits after discharge.
Discomfort associated with wearing the hip protector
Evaluation period: At initiation of wear; 1 day after initiation; and 1 week after initiation.
Hip range of motion (hip flexion/extension, abduction/adduction, external/internal rotation angles)
Evaluation period: At initiation of wear; 1 day after initiation; and 1 week after initiation.
Skin condition (presence of contact dermatitis and abrasions related to wear)
Evaluation period: Daily throughout the wear period.
Opinion survey regarding the lumbar support device (comfort, ease of donning, etc., as rated by participants and staff)
Evaluation period: During the observation period (conducted as a field survey).
Airbag deployment status (deployment time, deployment timing, and participant impressions of deployment via open-ended questions)
Evaluation period: When airbag deployment occurs due to a fall or other trigger (recorded each time an event occurs).
IMU sensor data during falls (acceleration waveform, peak acceleration [impact magnitude], fall direction [changes in sensor axes])
Evaluation period: At the time of each fall.

Novel Hip Protector Installation
Details: This airbag-type hip protector incorporates an IMU sensor positioned above the pelvis. Upon detecting a fall, it deploys in less than 0.1 seconds to protect the pelvic region. It should be worn continuously during hospitalization or institutional stay, except during toileting, changing clothes, and bathing.
