Abstract-Robot-assisted treadmill training is an established intervention used to improve walking ability in patients with neurological disorders. Although it has been shown that attention to the task is a key factor for successful rehabilitation, the psychological state of patients during robot-assisted gait therapy is often neglected. We presented 17 nondisabled subjects and 10 patients with neurological disorders a virtual-reality task with varying difficulty levels to induce feelings of being bored, excited, and overstressed. We developed an approach to automatically estimate and classify a patient's psychological state, i.e., his or her mental engagement, in real time during gait training. We used psychophysiological measurements to obtain an objective measure of the current psychological state. Automatic classification was performed by a neural network. We found that heart rate, skin conductance responses, and skin temperature can be used as markers for psychological states in the presence of physical effort induced by walking. The classifier achieved a classification error of 1.4% for nondisabled subjects and 2.1% for patients with neurological disorders. Using our new method, we processed the psychological state data in real time. Our method is a first step toward real-time auto-adaptive gait training with potential to improve rehabilitation results by optimally challenging patients at all times during exercise.

“…The recording of HRV in healthy people was used to modulate and monitor health care in previous studies [ 14 – 17 ]. Time domain including SI, SDNN, RMSSD, and PNN50 analyzes the changes in heart rate over time or intervals between successive normal cardiac cycles [ 18 ].…”

Objectives. This paper aims at exploring the effects of GUASHA on heart rate variability between healthy volunteers under normal condition and weightlifters after training sessions. Methods. Ten healthy male volunteers under normal condition and 15 male weightlifters after weightlifting training sessions were recruited into two groups. Electrocardiography was recorded before and immediately after 20-minute GUASHA. HRV was calculated in both the time domain and the frequency domain. Results. Stress index was reduced, while standard deviation of N-N intervals (SDNN), proportion derived by dividing the number of interval differences of successive N-N intervals greater than 50 ms, and root mean square of successive differences (RMSSD) were enhanced after GUASHA therapy in the two groups. The changes in SDNN and RMSSD were higher in the healthy men group than in the weightlifters group. In addition, low frequency was decreased whereas high frequency was significantly increased in healthy men after the GUASHA session. Conclusions. GUASHA therapy facilitates the parasympathetic nervous activity and modulates the balance between parasympathetic and sympathetic activities in both healthy men under normal condition and weightlifters after training sessions as indicated. Although the changes of the HRV parameters were similar in both groups, the responsiveness was more pronounced in healthy men than in male weightlifters.

“…In addition to psychological processes, physical effort, such as walking on a treadmill, can influence the psychophysiological measurements. HRV was shown to decrease during physical effort [49], mental stress [50] and negative emotions [51]. Galvanic skin response (GSR) is used as a direct measure for arousal [52], [53] and was found to increase during demanding tasks compared to a rest period [54].…”

While gait rehabilitation robots have become increasingly common to automate treadmill training, their efficacy is still controversial. Current robots lack the ability to react compliantly to the user's voluntary effort and cognitive intention. Bio-cooperative control concepts allow integrating the patient into the control loop as part of the plant rather than seeing him as a source of disturbance. Closed loop control is thereby performed on a physiological and psychological level. In this paper, we review the concept of bio-cooperative control implemented with neurological patients during robot-assisted gait rehabilitation. We highlight its clinical importance and review our work on control strategies that allow bio-cooperative control. We finish by discussing the future potential of bio-cooperative control in rehabilitation robotics.
