- Brief Summary
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.
- Detailed Description
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).

- Primary Outcome Measures
Name Time Method Change in gait velocity Baseline, after 2 weeks, after 4 weeks Habitual, preferred ("normal") walking speed (cm/s) quantified with the GAITRite electronic walkway system
- Secondary Outcome Measures
Name Time Method Change in spatial-temporal gait parameters (other than walking velocity) Baseline, after 2 weeks, after 4 weeks Gait parameters quantified with the GAITRite electronic walkway system
Change in subjective intensity of the Lyra training Baseline, after 2 weeks, after 4 weeks Subjective intensity assessed by self-report using the "Borg Rating of Perceived Exertion Scale" questionnaire; score range from 6 (no exertion at all) to12 (maximal exertion); higher scores represent greater subjective intensity and exertion of the Intervention training
Change in general mobility Baseline, after 2 weeks, after 4 weeks Timed Up and Go Test time (seconds); faster test times represent better general mobility
Change in functionality (DEMMI total score, absolute values) Baseline, after 2 weeks, after 4 weeks The de Morton Mobility Index (DEMMI) assesses functionality in different positions (lying, sitting, standing, walking); absolute values range from zero to 19 points; higher scores reflect better functionality
Change in fear of falling Baseline, after 2 weeks, after 4 weeks Subjective fear of falling assessed by self-report using the "Falls Efficacy Scale-International Version (FES-I)" questionnaire; results range from 16 to 64 Points; higher scores reflect greater fear of falling; total number of points will be analysed
Change in the THERA-Trainer Lyra machine settings Baseline, after 2 weeks, after 4 weeks Settings of the THERA-Trainer Lyra gait training machine
Change in functionality (DEMMI total score, scaled values) Baseline, after 2 weeks, after 4 weeks The de Morton Mobility Index (DEMMI) assesses functionality in different positions (lying, sitting, standing, walking); scaled scores range from zero to 100 points; higher scores reflect better functionality
Change in grip strength Baseline, after 2 weeks, after 4 weeks Grip strength (kg) of each hand (best result of two attempts for each hand used for data analysis)
Change in endurance Baseline, after 2 weeks, after 4 weeks Six Minute Walk Test; distance walked (meters) in six minutes; greater distance walked represents better endurance
