Brief Summary

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

The main objective of this study is to determine whether elderly people in rehabilitation setting show higher adherence to self-training when using computer-based-learning games (i.e. the so called serious games) than when performing conventional exercises. Secondly the study explores to which extend balance and mobility performances vary according to the mode of self-training.

The primary study hypothesis is that elderly people practice longer and more frequently with serious games than with a conventional exercise booklet. The secondary hypothesis is that patients experience a significant higher improvement in their balance capacity by using serious games compared to patients performing conventional exercises.

Detailed Description

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

Background:

The Swiss population, and in Europe in general, is getting older. Due to this evolving demographic trend, the need to develop specific healthcare services for this age group is becoming crucial. From the international literature, evidence-based findings have demonstrated that physical abilities of elderly people can be increased, and institutional placement and mortality can be reduced through specific inpatient rehabilitation programs (Bachmann, Finger et al. 2010).

Adults 65 years and older should carry out aerobic physical activities for at least 150 minutes of moderate intensity or for 75 minutes of high intensity in a week. Besides it is strongly recommended that senior adults perform strengthening exercises minimum twice a week and activities promoting balance minimum thrice a week (WHO 2010; NIH 2013).

In order to increase the training intensity and thus the independence in activities of daily living, older patients admitted in Kliniken Valens are instructed with a customized self-training program, in addition to the usual rehabilitation services. As for therapist-assisted sessions, this self-training program leads to significant improvement of patient's physical performance (Olney, Nymark et al. 2006) and represents therefore a proven, efficient and cost-effective intervention for inpatient settings. However, the compliance of elderly people to execute self-training exercises varies considerably. These programs are often considered as tedious and boring, and so prematurely stopped (Phillips, Schneider et al. 2004). An alternative to increase patient's motivation could be through serious games practice. Kliniken Valens has already experienced promising results with computer-based games such as the Nintendo Wii® (Schnurr and Oesch 2012).

Methods:

In this study participants are categorized in 4 strata according to their Berg Balance Score (BBS) (≤ 44 or ≥45) and their computer skills. Subsequently they are allocated randomly either in the intervention group or in the control group. In addition to the usual rehabilitation services provided in the clinic, participants of both groups are entitled to 2 additional time-slots (2 x 30 min/day) devoted to self-training and this during the 10 days of the intervention period. This protocol ensures the same conditions for each participant to perform or not self-training exercises. For safety measures, participants with a low BBS (\<45) perform the program in siting, whereas those with a higher BBS (≥45) practice in standing position (in front of a bench). The time frame of the intervention phase (from t1 to t2) lasts 10 working days and starts after self-training exercises have been instructed. In other words, t1 equates to approximately day 4 after the patient's admission in the clinic and t2 is 10 working days later, i.e. approximately day 16 after admission.

Intervention group:

The participants are instructed by experienced physiotherapists on serious games with Kinect®. Additionally, participants wear the Fit Bit® (an activity tracker device) and are encouraged to walk and climb stairs instead of using the escalator. Finally participants are asked to write down in a logbook, the frequency and duration of their self-training sessions.

Control group:

As in the usual rehabilitation services, experienced physiotherapists arrange a customized self-training program, instruct the exercises and deliver a hand-out. Additionally, patients are encouraged to walk and climb stairs instead of using the escalator. Finally participants are asked to write down in a logbook, the frequency and duration of their self-training sessions.

Data collection:

Data on self-training's intensity (primary outcome) are extracted from the logbook at post-intervention (t2) i.e. after the 10 working days of the intervention phase. The Berg Balance Scale and the Falls Efficacy Scale (secondary outcomes) are completed by a blinded researcher at pre- and post-intervention (before t1 and after t2) i.e. approximately at day 1-2 after admission and day 16-17 after admission.

Data analysis:

Data are analyzed using the statistical software for social sciences (SPSS). The statistical analysis of the two groups is performed following a normal distribution of data, with an unmatched t-test. For non-normal distributions, the Mann-Whitney U test is used.

serious games self-training program

Serious games are played, using Kinect® and Fit Bit®. This program is performed during the 10 days of the intervention on a self-training basis and 2 specific time-slot (2x30 min) per day are allocated for this program.

Group Type EXPERIMENTAL

serious games

Intervention Type DEVICE

Execution of computer-based games that stimulate patient's mobility. The game is displayed on a Television (TV) screen and the patient's movements are detected by the sensors of the Kinect® camera, requiring therefore no game console.

The Fit Bit®, a mobility tracker device, is attached at the patient's belt the whole day and measure all the trips performed and stairs climbed.

This serious games program is instructed individually by experienced physiotherapists.

Conventional self-training program

conventional physical exercises are performed during the 10 days of the intervention, on a self-training basis and 2 specific time-slot (2x30 min) per day are allocated for this program.

Group Type ACTIVE_COMPARATOR

Conventional self-training

Intervention Type OTHER

Participants perform conventional physical exercises that train their balance capabilities. There are instructed by experienced physiotherapists and are adapted to each patient's physical abilities. Detailed handouts are distributed to each participants.
