An interventional study of Tango Belt and Standard of Care (SOC) in Hip Injuries, Fractures, Hip and Fall Injury, sponsored by ActiveProtective Technologies, Inc. Completed at 10 sites in United States. Open to participants aged 65 Years and older. Per ClinicalTrials.gov, last updated 2025-06-13.
Sponsored by ActiveProtective Technologies, Inc · Not applicable, Interventional, and Prevention
Multi-center, comparative, non-significant risk adaptive study with retrospective controls.
After providing informed consent and being screened for eligibility, intervention subjects will be prescribed and provided an appropriately sized Tango Belt. The subject must demonstrate a minimum of 64% adherence to the use of the Tango Belt within 14 days of initiation to fully enroll in the study. Upon demonstration of at least minimum adherence, the subject will be provided the Tango Belt to wear continuously for at least 6 months, except during bathing, device charging, and as deemed by clinical staff.
The study will investigate the safety and effectiveness of the Tango Belt with the primary and secondary endpoints being taken every 3 months and at the end of the study run time from the electronic medical record. Additionally, ancillary endpoints on adverse events and device performance will be gathered.
This is a multi-center, comparative, adaptive, non-significant risk clinical trial conducted in the United States to assess the safety and efficacy of the Tango Belt within senior care settings. Effectiveness of the Tango Belt will be determined by analysis of evidence for the Tango Belt as an adjunctive intervention to the standard-of-care (SOC) to mitigate major hip injuries from falls in an older adult population at-risk for fall injury as the primary endpoint. Performance of the Tango Belt to mitigate fall injuries that result in hip fracture, emergency room visits, and hospitalizations will be secondary endpoints. The performance of the device is determined by the comparison of the proportion of fall-related major hip injuries in the intervention group as compared to the proportion of fall-related major hip injuries in a retrospective control group utilizing only SOC. SOC utilization will be verified for each clinical site enrolled. An adaptive trial design will be utilized to allow an initial efficacy target to be evaluated at 6 months; if the initial target is not met, then a second cohort of sites and subjects will be enrolled for an additional 6 months to allow a lower efficacy target to be evaluated.
Safety of the device will be determined by analysis of adverse events as an ancillary endpoint.

Exclusion Criteria:
The intervention group will be assigned a Tango Belt to be worn around the waist for up to 24 hours a day (removed for bathing, charging of device and upon request) for 6 months. The Tango Belt (the "Device") is a wearable belt designed to enable safer mobility of geriatric individuals (≥ 65 years of age) at risk for fall injury by mitigating major hip injuries due to falls by deploying an airbag around the hips upon sensing a serious hip-impacting fall-in-progress to protect the hips from ground impact forces.
Device: Tango Belt · Other: Standard of Care (SOC)
The clinical site's electronic medical record (EMR) database will be reviewed determine their long-term care patient population's initial eligibility for meeting the study inclusion criteria beginning at the time frame 6 months prior to the institutional review board (IRB) approval date. Subjects eligible for the control group must meet the requirements of the inclusion and exclusion criteria except for the waist circumference and need for consent. Eligible subjects' electronic health records will be mined for the baseline, midpoint, and final study metrics.
Other: Standard of Care (SOC)
The Tango Belt is a patient-contacting electronic device made out of medical grade plastics and biocompatible fabrics worn around the waist. The Tango Belt contains a fall-in-progress detection algorithm which can detect a serious hip-impacting fall-in-progress using built-in sensors and deploy an automotive-grade cold-gas airbag to protect the hips from ground impact forces. When connected to Wi-Fi, the Tango Belt can send automated fall and impact alerts to caregivers and Healthcare Providers (HCPs) while recording motion and event data, which can then be analyzed for usage-based metrics viewable via a companion mobile app and/or desktop app. Alerts are sent in the form of short message service (SMS) texts and emails to alert recipients designated in the mobile or desktop Companion App. The Tango Belt can also detect non-serious hip-impacting or non-hip impacting falls in which the wearer may have incurred a minor injury (i.e., not a major hip injury) and/or may be unable to get up.
The standard of care (SOC) in the US for managing the fall risk of geriatric patients is the CDC's Stopping Elderly Accidents, Deaths, and Injuries (STEADI) initiative, which implements the America and British Geriatric Societies'' Clinical Practice Guidelines for fall risk management. The STEADI algorithm consists of tools and resources for healthcare providers for fall risk screening, assessment, and interventioniv,v. Screening and assessment includes identifying fall history and modifiable factors related to fall and fall injury risk (e.g. fear of falling, gait, strength, balance, medications, comorbidities, etc.); then interventions to reduce the fall and fall injury risk are applied based upon assessment findings, and can include physical therapy, medication adjustments, patient education, bed and chair alarms, bed rails, etc.

Number and Severity of Adverse Events
An Adverse Event is any untoward medical occurrences in a patient or subject receiving an investigational medical device and does not necessarily have to have a causal relationship with the device under investigation. An AE can therefore be any unfavorable and unintended sign (including abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical device whether or not considered related to the medical device. Any fall event is considered an AE for this study. A Severe Adverse Event is any AE that results in death, is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization or results in persistent or significant disability/ incapacity.

Time frame: 6 months
The intervention group was recruited via clinical site health record review for the inclusion/exclusion criteria available and waist circumference obtained by sub-investigator on-site and offered informed consent. The control group was determined via historical clinical site health record review determining subject eligibility based on inclusion/exclusion criteria except waist circumference and did not need consent.
