DESIGN AND DEVELOPMENT OF 3D PRINTED MYOELECTRIC ROBOTIC EXOSKELETON FOR HAND REHABILITATION

rehabilitation. Based on the EMG signals measured from the muscles responsible for the hand motion, the designed mechatronic system detects the intention of hand opening or hand closing from the stroked subject. Based on an embedded controller and five servomotors, the low cost robotic system is able to drive in real time three degrees of freedom (DOFs) for each finger. The real tests with stroked subjects showed that the designed hand exoskeleton architecture has a positive effect on the motion finger range

DESIGN OF SMART ROBOT FOR WRIST REHABILITATION

for wrist rehabilitation is designed. This robot is intended for repetitive exercises without therapist intervention. Hold the two sets of wrist movement: flexion/extension and radial/ulnar derivation. Distinguished by its compact mechanism design, the developed wrist rehabilitation robot (HRR) offers high stiffness with a total absence of any friction and backlash. Based on EMG signal, the smart robot can understand the patient pain degree. Two features extractions are used to estimate the pain

Assessment of the utility of ultrasonography with high-frequency transducers in the diagnosis of postoperative neuropathies

treatment of the median nerve (1), after surgical treatment of the ulnar nerve (2) and other postoperative neuropathies (3). All patients underwent the interview, physical examination and ultrasound examination. The ultrasound examinations were performed with Esaote MyLab 50 and MyLab 60 systems. Based on the clinical and US examinations, the patients were qualified for either surgical (51 cases) or conservative treatment (20 cases). An EMG examination was also performed in certain patients (60 cases

Analyzing and Processing EEG-based Multichannel Signals Acquired during Sleeping

Processing of signals acquired from sensor systems needs accurate algorithms to extract information of interest concerning the problem under study. In this work Empirical Mode Decomposition method is used on EEG signals obtained during polysomnography examination, when electromyographic (EMG) signals are acquired too. EMD method decomposes a signal into components named Intrinsic Mode Functions (IMF) which can exhibit important time-frequency information related to signals under observation

The use of a probe stabilizer to reduce musculoskeletal overload of ultrasound operators in routine diagnostic echocardiographic imaging

Electromyography-sensor and gyroscope During acquisition, the sonographer wore a small device containing an electromyography (EMG)-sensor and gyroscope (ErgoNode®, Usono, Eindhoven, the Netherlands). The EMG-sensors were positioned on the inside and the outside of the forearm. A surfaced EMG was used to evaluate the right forearm extensor and flexor muscle activity during ultrasound examination, representing the wrist joint loading. In this study we did not evaluate the absolute amount of muscle activity, but

High-frequency ultrasound in carpal tunnel syndrome:assessment of patient eligibility for surgical treatment

men, aged 28–70, mean age 55.2) with scheduled surgeries of CTS on the basis of clinical symptoms, physical examination performed by a neurosurgeon and a positive result of EMG testing. The ultrasound examinations of the wrist were performed in all these patients. On the basis of the collected data, the author has performed multiple analyses to confi rm the usefulness of ultrasound imaging in assessing patient eligibility for surgical treatment of CTS. Results: US examinations showed evidence of

Assessment of the utility of ultrasonography with high-frequency transducers in the diagnosis of posttraumatic neuropathies

neuropathies of the following peripheral nerves: median, ulnar, common peroneal, digital, cutaneous in the deltoid area, mental, PIN and RSNR. In 21 patients, nerve injuries were partial, and in 24 – complete. In 2 cases, the nerve was entrapped between bony fragments. 17 of 21 patients with partial nerve injuries (80.95%) underwent an EMG examination. No functional tests were conducted in the cases of complete injuries when ultrasound imaging had confi rmed the result of the clinical examination. All
