“…Although the WB is a widely used tool in rehabilitation, the lack of quantitative data makes the evaluation of the patient's evolution difficult. To solve this problem, the system developed in this work can be used anywhere, and the generated data can easily be stored, allowing a detailed analysis of the patient's performance, such as in the device used by Bizovska et al (2017). In their work, a validation test was performed on a WB instrumented with an accelerometer capable of measuring and storing the tilt of the platform.…”

“…Therefore, an instrumented WB capable of measuring the gradient vector of the MD and the displacement of the CoP during balance training could provide more assertive data for health professionals. These data can be used to develop a more effective treatment, as they allow a detailed analysis of the body response to the oscillations caused by the WB (Bizovska et al 2017). Therefore, the aim of this study was to develop and validate a supervisory system and the data acquisition based on hardware (WB) and software (control app) elements that allow the dynamic balance evaluation.…”

Introduction The wobble board (WB) is an unstable platform that allows proprioceptive balance training. However, because it is a passive device, it does not provide quantitative data about the training, making it difficult for the therapist to track their patients' performance. The aim of this study was to develop and validate a supervisory system and the data acquisition based on hardware (WB) and software (control app) elements that allow the dynamic balance evaluation. Methods An electronic system was placed on a WB. Its tilt was measured using an accelerometer. A supervisory system, capable of calculating the mass distribution (MD) and the center of pressure (CoP), was developed. Firstly, in order to validate the system, a functional test was performed; then, thirty volunteers were submitted to the test protocol approved by the research ethic committee of the University of Mogi das Cruzes. Results The results of the functional tests showed that the supervisory system was able to correctly calculate the MD and the CoP. In the test with volunteers, no significant difference was observed between the tests with and without visual feedback of the balance oscillation. Conclusion The developed system is portable and capable of storing data for future analysis. The combination of the tilt's, MD's, and CoP's values generated a detailed analysis of the exercises performed, allowing the therapist to track the performance of the patients and adapt the exercise to their needs, making the treatment using the WB more effective.

Ensuring the regularity and correctness of rehabilitation exercises in the home environment is a prerequisite for successful treatment. This clinical study compares balance therapy in the home environment on a conventional balance mat and an instrumented wobble board, with biofeedback supported by a rehabilitation scheme realized as web-based software that controls the course of rehabilitation remotely. The study included 55 patients with knee injuries. The control group consisted of 25 patients (12 females and 13 males, mean age 39 ± 12 years) and the study group of 30 patients (19 females and 11 males, mean age 40 ± 12 years). Treatment effects were compared using the ICS Balance Platform measurement system. Measurements showed significant differences in the change in ICS Balance platform parameters representing the dynamic stability of the patients. The dynamic stability improved more with the instrumented wobble board. The study did not show an influence of different methods of communication with patients during home-based rehabilitation.

“…These sensors measured greater mediolateral tilt variation and angular velocity in individuals with functional ankle instability during unilateral steady standing on a wobble board compared to a control group [29]. An instrumented wobble board also measured oscillations during steady standing reliably and in good agreement with force plate center of pressure fluctuations in young adults [31]; however, the validity of wobble board assessments in older adult balance remains unknown. Finally, aging and virtual visual feedback effects were measured with an instrumented wobble board during active balance training [24]; however, these IMU-based metrics were not validated.…”

Providing aging adults with engaging, athome balance therapy is essential to promote long-term adherence to unsupervised training and to foster independence. We developed a portable interactive balance training system that provides real-world visual cues on balance performance using wobble board tilt angles to control the speed of a robotic car platform in a three-dimensional environment. The goal of this study was to validate this mobile balance therapy system for home use across the lifespan. Twenty younger (18-39 years) and nineteen older (58-74 years) healthy adults performed balance training with and without visual feedback while standing on a wobble board instrumented with a consumer-grade inertial measurement unit (IMU) and optical motion tracking markers. Participants performed feedback trials based on either the robotic car's movements or a commercially-available virtual game. Wobble board tilt measurements were highly correlated between IMU and optical measurement systems (R > 0.84), with high agreement in outcome metrics (ICC > 0.99) and small bias (mean < 3%). Both measurement systems identified similar aging, feedback, and stance type effects including (1) altered movement control when older adults performed tilting trials with either robotic or virtual feedback compared to without feedback, (2) two-fold greater wobble board oscillations in older vs. younger adults during steady standing, (3) no difference in board oscillations during steady standing in narrow vs. wide double support, and (4) greater wobble board oscillations for single compared to double support. These findings demonstrate the feasibility of implementing goal-directed robotic balance training with mobile tracking of balance performance in home environments.
