Brief Summary

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

This study aims to address if robot assisted physical training can prevent functional decline during acute hospitalisation in older geriatric patients.

Design: blinded RCT. Patients: n = 488. Primary outcome is functional decline, assessed by Barthel-Index and 30s chair stand test. One- and three months follow-up.

Detailed Description

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

Introduction:

Inactivity during hospitalisation is associated with significant risk of functional decline especially in older patients. This have major impact on the individual level due to decreased wellbeing and higher level of dependency and on the society level due to increased caregiver burden following hospital discharge. This study aims to address if robot assisted physical training can prevent functional decline during acute hospitalisation in older geriatric patients.

Methods:

ROBUST is a blinded RCT. Patients (n = 488) admitted with acute medical illness to Department of Geriatric Medicine, Odense University Hospital will be randomised to usual care and robot assisted active strength training of lower extremities twice daily (intervention group) or usual care and robot assisted passive sham training (control group) until discharge. Both groups will receive protein supplements.

Inclusion criteria: ≥65 years of age, able to ambulate before hospitalisation, expected length of stay ≥2 days.

Exclusion criteria: Able to ambulate without assistance during current hospitalisation, severe dementia, delirium, conditions contradicting robot training.

The primary outcome, functional decline, will be assessed by Barthel-Index and 30s chair stand test.

Secondary outcomes include Quality of life (EQ-5D), Geriatric Depression Scale, Fear of falling (FES-I), cognition (MMSE), qualitative interviews, falls, caregiver burden, discharge destination, readmissions, healthcare costs, sarcopenia, and mortality.

Outcomes will be assessed at admission, discharge, and one- and three months follow-up. Data on comorbidity, medications, blood samples, and clinical frailty scale will be collected.

Discussion: This study will investigate the effects of in-hospital robot assisted strength training on functional status in older patients with multimorbidity.

Study Groups

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

Control group

Participants in the control group will receive usual individualized training with a physiotherapist and passive sham training of lower extremities with the rehabilitation robot twice a day until day of discharge. The physiotherapist will be blinded to allocation. Sham training consists of 3 sets of 8 passive repetitions with each leg twice a day.

Group Type SHAM_COMPARATOR

Passive Robot assisted physical training during acute hospitalisation

Intervention Type OTHER

Passive training is delivered by an innovative training robot (ROBERT®). The robot is handled by staff who attaches the robot to the patient's leg. The staff programs the movement, whereby the robot remembers the movement. The robot holds the patient's leg and perform passive extension of hip and knee. ROBERT® moves the leg independently without the patient using any muscle power.

Training is defined as a minimum of three sessions before discharge.

Intervention group

The intervention group will receive usual individualized training with a physiotherapist and active strength training of lower extremities by the robot twice a day until day of discharge. The physiotherapist will be blinded to allocation. Training will focus on the muscle groups in the lower extremities, which are used to get up from a chair and walk around (thigh- and calf muscles). Active training consists of 3 sets of maximum repetitions with a minimum of 65% (65-80%) intensity of 1 RM with each leg twice a day.

Group Type ACTIVE_COMPARATOR

Active Robot assisted physical training during acute hospitalisation

Intervention Type OTHER

Active training is delivered by an innovative training robot (ROBERT®). The robot is handled by staff who attaches the robot to the patient's leg. The staff programs the exercise movement, whereby the robot remembers the movement. The robot holds the patient's leg and perform extension of hip and knee. The patient must use their muscular power to stretch the leg while ROBERT® provides resistance.

Training is defined as a minimum of three sessions before discharge.
