Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will assess whether the use of technology using the Virtual Gate Device (VGD) will prevent or minimize the development of hospital acquired Sarcopenia resulting from Immobilization.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Modern advances in prevention, medical care, and treatments have resulted in an ever-increasing life expectancy and aging of the population. As a result, it is imperative that health care professionals and policy makers develop strategies and new technologies that enable older people to enjoy their advancing years in good health.

Sarcopenia, an age-related decrease in muscle mass, is a major factor in functional decline and frailty and leads to poor quality of life and increased health care costs in older age groups. Because sarcopenia is known to be exacerbated at the time of acute hospital admission, the development of new technologies for the prevention and diagnosis of sarcopenia will have important ramifications in promoting healthy aging in both the acute care and ambulatory settings.

A pilot interventional self-controlled study will be performed in an internal medicine department (internal medicine ward Het) at the Rambam Health Care Campus in Haifa.

Subjects will be evaluated for the risk of sarcopenia by acceptable screening instruments as well as B-mode portable ultrasound. They will then be treated using a stocking-like Virtual Gait Device (VGD) which will be applied to one randomly-assigned lower limb. The VGD is a technology that uses fussy-logic technology to stimulate calf muscles in synchrony with the patient's heartbeat, enabling a virtual gait in patients who have limited mobility.

Confidentiality will be achieved by applying a unique identifier to each trial subject in accordance with Good Clinical Practice standards.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

Eligible subjects will be scored either as low-risk for sarcopenia-related adverse outcomes (\<4) or high risk (≥4) via the SARC-F scoring system, and will be evaluated for sarcopenia of the lower limbs using a B-mode portable ultrasound machine used for standard clinical practice at the Rambam Health Care Campus. A VGD will be applied to one randomly-assigned lower limb. The VGD will be operated constantly (apart from times that the patient is being bathed or undergoing investigations or procedures) providing intermittent stimulations as outlined in the investigator brochure. On day 4, ultrasound of the lower limbs will be repeated for all subjects, with repeat imaging every subsequent second day for admissions extending beyond 4 days and a maximum of 10 days after the application of the VGD. The study will include all eligible patients in the internal department (internal medicine ward Het) who agree to participate in the study and provide written informed consent.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Virtual Gate Device (VGD)

The Virtual Gait Device (VGD) is a technology that uses fussy-logic technology to stimulate calf muscles in synchrony with the patient's heartbeat, enabling a virtual gait in patients who have limited mobility. The stocking-like device is especially useful in older patients who are acutely hospitalized and thus at risk for sarcopenia. While physical activity and physical resistance training are well-documented as preventive measures for sarcopenia, active physical exercise is an unrealistic option for most acutely hospitalized, mobility-limited, older patients. The VGD is a practical alternative that is simple to operate. One pilot study in the orthopedics department in Hadassah Medical Center in Jerusalem, Israel was performed on patients with fractured ankles with the goal of muscle wasting prevention. The VGD will be provided by the manufacturer for use in this pilot clinical study.
