There are some essential problems with the arguments presented in the above paper about the design of a sliding-mode controller for functional electrical simulation (FES) induced control of knee-joint angle. In this note, we show that applying some approximations in derivation of the control law violates the reaching condition and could introduce some parasitic unmodeled dynamics in the sliding-mode control ...

The functionality of prosthetic limbs is restricted by the limited availability of sensory feedback. The goal of the present research is the development of a multichannel microelectrode array for the presentation of sensory information directly to the sensory afferent neurons of the transected peripheral nerve of an amputee. Intraneural electrode arrays were developed and implanted in the proximal stump of the transected sciatic nerve in 18 New Zealand White rabbits and monitored for chronic functionality. Several novel nerve regeneration implant designs employing axially oriented Platinum/Iridium wire arrays and regeneration tubes were explored. Somatosensory evoked potentials were monitored via chronically implanted epidural electrodes. A behavioral technique was used to monitor stimulus perception; an electrical stimulus was delivered to the implanted nerve followed by an airpuff to the eye with monitoring of the resultant eye-blink reflex. In this classical conditioning technique, the rabbits associate the two stimuli such that electrical stimulation of the sciatic nerve without an airpuff elicits an eye- blink. Neurophysiological and behavioral tests have demonstrated chronic single channel electrode functionality for greater than 2 years in implanted animals. This research supports the possible viability of an implanted neuroelectric interface in providing chronic sensory feedback in humans.
The paper discusses the real-time realization of EMG signature identification for posture mapping of the upper trunk of a paraplegic as is required for controlling electrical stimulation of his/her lower limb nerves to facilitate walker-supported walking . The above method has been applied by the authors to 4 complete upper motorneuron paraplegics, with spinal cord lesions at levels T5/6 to T11/12. The purpose of the above approach is to provide naturally-controlled walking capabilities to such paraplegics, rather than using hand switches which are unnatural and, diverting the patient's concentration from his above-lesion posture (see Figure 1 and 2). For adequate control of the stimulating channel, complete posture mapping, i.e., signature identifications and control decisions, must be made in less than 0.3 seconds, else, smooth walking is hampered which in turn affects the patient's balance.
Purpose: The purpose of this study was to compare post contraction hyperemia after electrical stimulation with persons with upper extremity paralysis caused by upper motor neuron disease with able-bodied persons. Methods: Thirteen able-bodied persons and eleven individuals who had upper extremity paralysis caused by upper neuron disease were enrolled in the study. The blood flow of basilic vein was measured by ultra sound system before the electrical stimulation and 30 seconds after the stimulation. Electrical stimulation was done to the biceps brachii muscle. The strength was 10mA, frequency was 70Hz, stimulation time was 20 seconds. The Dynamid electro stimulation system was used for the electro stimulation and the TOSHIBA Xario ultrasound system was used for evaluating the blood flow. Results: The mean blood flow of the able- bodied group and paralysis group before the electrical stimulation was 60 ± 20 ml/min (Mean ± SD) and 48 ± 25ml/min. After the electrical stimulation, both increased to 117 ± 23 ml/min and 81 ± 41 ml/min. Conclusion: It was possible to measure the post contraction hyperemia by ultra sound system. Both blood flow of able-bodied persons and persons with upper extremity paralysis increased after the electrical stimulation due to post contraction hyperemia.
There are some essential problems with the arguments presented in the above paper about the design of a sliding-mode controller for functional electrical simulation (FES) induced control of knee-joint angle. In this note, we show that applying some approximations in derivation of the control law violates the reaching condition and could introduce some parasitic unmodeled dynamics in the sliding-mode control loop. Therefore, the proposed controller cannot force the system into a sliding-mode regime, and its ability of producing a robust control loop with good tracking performance is theoretically under question.
Functional Electrical Stimulation (FES) is a technique to artificially stimulate motor nerves in order to restore motor/sensory functions for assistive and therapeutic applications. This preliminary study attempts to detect differences in the perception of transcutaneous FES in upper limbs. Three chronic stroke survivors participated in the study. Multi-field electrodes were used to selectively activate the targeted areas over the wrist-finger flexors, wrist-finger extensors, biceps, and triceps muscles. Results showed no significant correlation between the applied current and pain ratings. Differences in the rating of pain in different fields over the four targeted areas were observed. The initial results suggest that here is a common pattern to most subjects for each area of the upper limb.
Electric pulp test is a method to examine the vitality of dental pulp using the electrical stimulation. During the pulp test, the current stimulates intradental nerve, and give severe pain to patients. Some studies were accomplished to measure the responses of subjects by stimulating over the sensory threshold. But these studies were focused on the time delay of subject's response after stimulating over the threshold. The purpose of this study was first to measure the excessive stimulation time during pulp testing by means of EMG in anterior belly of digastric muscle, voice, and finger movement, secondly, to determine whether the excessive stimulation time could be reduced by the specially designed automatic circuit breaker on the basis of EMG signal
An assessment is made of the efficacy of the impedance catheter in sensing relative volumetric changes in the right ventricle as a means of monitoring the hemodynamic status during an arrhythmia. During electrophysiologic testing, 37 arrhythmias were induced in 12 patients. Stroke impedance (peak value minus minimum value) was significantly lower in hemodynamically unstable ventricular arrhythmias (ventricular tachycardia and ventricular fibrillation) than in stable tachyarrhythmias (supraventricular tachycardia and stable monomorphic ventricular tachycardia). Implementation of hemodynamic sensing can improve arrhythmia specificity of the sensing algorithm of future implantable defibrillators and may add options for selective pace termination or cardioversion.<<ETX>>
An experiment on the discrimination of time sequential stimuli of auditory nerves was carried out, and its result was compared with results for the vibrotactile sense. An extracochlear prosthesis that stimulates via an electrode superficially placed on the round window membrane of the cochlea is described. A new speech coding method is proposed for the prosthesis, for transmitting the pitch signal and the second formant frequency. In this method, an additional stimulation pulse is inserted among the pitch pulses, and the time delay from pitch to additional pulse is proportional to the second formant frequency. This coding method has been seen to be effective in recognizing about 60% of Japanese vowels.<<ETX>>
