The purpose of this study is to evaluate the effects of a sensor-based balance training with exergaming feedback on balance skills in chronic stroke patients.
Stroke is a leading cause of disability globally, with many survivors experiencing persistent balance impairments that affect the quality of their life. In this context, the use of balance-focused rehabilitation might represent a promising strategy over traditional methods. The integration of biofeedback and advanced technology in rehabilitation, such as audiovisual feedback, can enhance cortical activation, sensory integration, and patient engagement. Exergaming, a specific form of biofeedback, exhibits potential in improving functional recovery and motivation in stroke rehabilitation. In fact, visual feedback has shown effectiveness in chronic stroke patients. Given the rising incidence of stroke and the associated challenges, it is crucial to explore new intervention strategies that leverage technological advancements for better balance recovery. Previous studies have shown promising results in subacute stroke patients using an integrated biofeedback system that combine inertial measurement units (IMUs) and a sensorized force platform. The current study aims to evaluate the effects of sensor-based training with exergaming feedback on balance functions in individuals with chronic stroke.

10 sessions of sensor-based balance training with exergaming feedback. For this training an adaptive integrated audio-visual feedback system composed of five IMUs and a force platform connected wirelessly to a computer has been used. The training protocol include exercises of balance control, encompassing a total of five distinct exercises: i) Latero-lateral load shifting while seated; ii) Load shifting while standing: latero-lateral and antero-posterior, to simulate the balance control performed during the day; iii) Load control during sit-to-stand; iv) Gait swing and loading phase response: to stimulate a correct load shifting during the swing and stance phase; v) Latero-lateral load shifting with knee flexion.
10 sessions of usual balance training. The training includes: gait control exercises, weight shifting, and relies on both stable surfaces (i.e., steps) and unstable surfaces (i.e., oscillating platforms and various-sized fitballs). The protocol encompassed the application of stabilization techniques and the reaching of targets with the upper limb during upright position emulating the activity of daily living.

The Berg Balance Scale (BBS)
The BBS is a clinical scale used to quantitatively assess balance ability after stroke. Range score from 0 to 56 points, a higher score represents an improvement.
Time frame: Before training (t0); after 4 weeks of treatment (t1); after 8 weeks from the baseline (t2)
The Canadian Neurological Scale (CNS)
The CNS is a clinical scale used to quantitatively assess neurological status of stroke patients. Range score from 1.5 to 11.5, a higher score represents an improvement.
Time frame: Before training (t0); after 4 weeks of treatment (t1); after 8 weeks from the baseline (t2)
The National Institutes of Health Stroke Scale (NIHSS)
The NIHSS Clinical scale used to quantitatively assess neurological status of stroke patients. Range score from 0 to 42, a lower score represents an improvement.
Time frame: Before training (t0); after 4 weeks of treatment (t1); after 8 weeks from the baseline (t2)
The Barthel Index (BI)
The BI is a clinical scale used to quantitatively assess functional independence after stroke. Range score from 0 to 100 points, a higher score represents an improvement.
Time frame: baseline (t0); 4weeks (t1 - end of treatment); 8weeks (t2 - 1 month follow-up)
The Rivermead Mobility Index (RMI)
The RMI is a questionnaire used to quantify mobility disability after stroke. Range score from 0 to 15 points, a higher score represents an improvement.
Time frame: Before training (t0); after 4 weeks of treatment (t1); after 8 weeks from the baseline (t2)
Postural stability
Postural stability has been recorded via a stabilometric platform to evaluate the oscillations of patients while standing in the upright position with open/closed eyes. The lenght of the Center of Pressure (CoP) has used to assess the change in postural stability. A reduction in the CoP represents an improvement.
