Effect of THERA-Trainer Lyra Gait Training in Addition to Physical Therapy on the Mobility of Geriatric Rehabilitation Inpatients Compared to Physical Therapy Alone: Randomized, Active-controlled, Parallel Group, Intervention Trial
Effect of THERA-Trainer Lyra Gait Training in Addition to Physical Therapy on the Mobility of Geriatric Rehabilitation Inpatients Compared to Physical Therapy Alone: Randomized, Active-controlled, Parallel Group, Intervention Trial
This study evaluates the effect of the addition of gait training to physical therapy on the gait of geriatric rehabilitation inpatients. Half of the patients will receive gait training with a gait training machine and conventional physical therapy in combination, the other half of the patients will receive conventional physical therapy alone.
The geriatric rehabilitation inpatients recruited for this study primarily have difficulties with muscle weakness and walking generally due to a prolonged period of bed rest (as opposed to patients who primarily have cognitive disorders or neurological diseases), generalized muscle weakness and deconditioning. The rehabilitation goal for these patients is to be discharged home (not institutionalized) with improved mobility. Geriatric patients require intensive training in order to reach their pre-hospital levels of mobility and physical functional performance. Usual care involves physical therapy sessions, generally six times per week. Regaining mobility is crucial for quality of life and functional independence.
The aim of this intervention trial is to compare the effectiveness of Lyra gait training plus conventional physical therapy (intervention group) on gait compared to conventional physical therapy alone (control group) in geriatric rehabilitation patients. We hypothesize that, post-intervention, the intervention group will have better mobility and physical functional performance than the control group. Trial results will provide physical therapists and rehabilitation physicians with valuable information to better treat their inpatients and more efficiently use the limited time available for inpatient physical therapy sessions. Specifically, physical therapists should be better able to determine if the benefit of the Lyra gait trainer for geriatric rehabilitation inpatients with primarily muscle deconditioning is strong enough to warrant their extra time investment of providing the Lyra gait training. Results should also help determine in the future if the target population should continue with outpatient therapy after their discharge home. If this trial supports our hypothesis, then the trial results will provide data needed for the sample size calculation for a subsequent, larger trial.
The THERA-Trainer Lyra (from Ability AG, distributed by medica Medizintechnik GmbH) is an automated gait trainer with adjustable body weight support (no exoskeleton) and adjustable pedals (not a treadmill) that move in a physiological gait pattern derived from natural human walking movements. The upright position and the repetitive movement patterns activate muscle memory and allow safe gait training at the individual's performance limit throughout rehabilitation. The Lyra gait training is used to regain walking ability, improve gait speed, improve endurance and improve the gait pattern in geriatric rehabilitation patients.
Ten patients should be enrolled in this study:
Intervention group (n=5): Lyra gait training thrice weekly and conventional physical therapy (6 times per week) during inpatient period. After discharge home, continuation of thrice weekly Lyra gait training and discontinuation of physiotherapy.
Control group (n=5): Conventional physical therapy (6 times per week) during inpatient period. After discharge home, discontinuation of physical therapy.
At enrollment (Visit 1), all participants will be rehabilitation inpatients. The duration of the inpatient period will be determined clinically based on medical need and will thus vary from patient to patient. The average length of stay for the targeted population is approximately two weeks. Visit 2 will be performed shortly before the patient is discharged home. For each participant, the outpatient period (between Visit 2 and Visit 3) will be the same duration as the inpatient period (between Visit 1 and Visit 2).
