The paper proposes a telerehabilitation solution for hand Therapy. The proposed solution has two main components: the recovery part itself and the device for recording physiological parameters. We chose to record the heart rate and the EMG signal. To monitor heart rate during recovery exercises, we used a photoplethysmogram (PPG) sensor that picks up the earlobe signal. EMG module connected directly to the electrodes placed on the muscle whose activity is to be monitored for recording the EMG signal. To perform the recovery exercises, we made a game in Unity3D with several levels and degrees of complexity. After completing each level, the patient obtains a score depending on the correctness with which he performed the exercise. Before starting the recovery program, each patient was monitored with a Holter system for 24 hours, and an analysis of heart rate variation was performed. These results are considered a reference for analyzing the rhythm variability performed during the recovery program.

The paper proposes a solution for monitoring of cardiovascular parameters during home-based hand rehabilitation. The most important cause of long-term disability in Europe is cerebral vascular accident (CVA) or stroke. The effects of stroke can vanish after a short period or can remain for the rest of the life depending on therapeutic program. The system developed for this study is not only therapeutically devices that allow the movement of hand for physical exercises controlled by electromyography (EMG) but also record one or more biomedical parameters such as: electromyogram (EMG), electrocardiogram (ECG), pulse wave, heart rate (HR), temperature, respiration rate, non-invasive blood pressure (NIBP) or oxygen concentration in the blood (SpO2). These physiological parameters are selected according to the physician’s prescription and the patient needs. In this paper it is presented an application that refers to the hand rehabilitation of post-stroke. It was observed the cardiovascular system status, analyzing the heart rate variability. During therapeutic procedure it was recorded ECG (1 lead) and pulse wave (using an ear lobe sensor). After that HRV was calculated for each signal. The results were used to determine the stress level induced by the rehabilitation program.

This paper presents some results of the brain electrical activity’s analysis in case of the magnetic stimulation. It was recorded and analyzed the electroencephalography (EEG) signal during magnetotherapy procedures in abdominal region, considering this fact like as a possible exposure of subject at magnetic field. The recordings of EEG signals are performed on 13 healthy volunteers in three conditions (before, during and after magnetic stimulation), using three types of sinusoidal pulses. By means of the frequency domain representation (power spectral density PSD) and a statistical processing there were distinguished some possible EEG signal modifications due to magnetic fields.

These biological signals, such as those from the heart and brain, are routinely used for both diagnostic and therapeutic purposes. The aim of this study is to obtain a software application used to observe the ECG activity during pulse magneto therapy taking into account that this procedure is frequently used for a lot of diseases.

On the basis of the measured levels of electromagnetic environment due to radio-communication transmitters and mobile communication systems (90 MHz ÷ 2.2 GHz), both the relative exposure levels - RE and the relative specific absorption rate -RSAR were calculated. The specific absorption rates - SAR were determined by simulations made with CST Microwave Studio software using some head models: a spherical model, a homogeneous SAM model and a complex head model proposed by authors. In this scope it was proposed a virtual human head model using successive magnetic resonance imaging (MRI) sections. The investigations were performed in a large frequency range including typical exposure fields in some areas. Thus, it was made a comparison between SAR, obtained using two simple homogeneous human head models and the correspondent results obtained using the proposed complex model. The determined parameters were also compared with those recommended by the International Commission on Non-Ionizing Radiation protection-ICNIRP.

In this paper we study the influence of magnetic field, used for basic physiotherapy procedures, on brain electrical activity by analyzing the EEG signal. The recordings are performed in three conditions (before, during and after magnetotherapy) from electrodes placed in the scalp in the occipital region. For magnetotherapy procedure was used typical equipment with cylindrical coil of 60 cm diameter. We record EEG from 13 healthy volunteers for 3 types of sinusoidal pulses. The frequency analysis was performed for all recorded signals and was evaluating the power spectral density (PSD) for delta (0.5 to 4 Hz) and alpha (8 to 13 Hz) waves.
