A Systematic Review of Isometric Lingual Strength-Training Programs in Adults With and Without Dysphagia. This 'restrictive' effect of TES on tongue pressure may have the potential to be used during a resistive exercise paradigm for tongue elevation during swallowing. Gerodontology. J Acoust Soc Am. NLM Five experiments were conducted with cochlear implantees to investigate the hypothesis that perceptual effects other than loudness result from changes in pulse duration for durations from 50 to 266 microseconds. This site needs JavaScript to work properly. PLoS One. doi: 10.1371/journal.pone.0201771. Direct Current (DC) - Galvanic. Electrical pulses were delivered at 100 Hz (1-ms pulse duration) and 20 Hz (5-ms pulse duration) for the high (HF) and low (LF) frequency protocols, respectively. Functional responses from guinea pigs with cochlear implants. Optimization of pulse duration for sensory stimulation was investigated by Howson (1978).  |  2014 Jan;135(1):334-41. doi: 10.1121/1.4835735. Barikroo A, Hegland K, Carnaby G, Bolser D, Manini T, Crary M. Dysphagia. J Acoust Soc Am. 1999 Aug;106(2):998-1009. doi: 10.1121/1.428052. The MVCs and stimulation intensity required to generate 25% MVC for the 2 pulse durations was established. Immediate effects of transcutaneous electrical stimulation on physiological swallowing effort in older versus young adults. Would you like email updates of new search results? Pulse duration: the amount of time the current flows in one direction. Am J Speech Lang Pathol. 2014 May-Jun;35(3):e63-74. Set frequency and pulse duration to generate 20% MVIC target peak force Either the stimulation pulse duration or frequency of a 300 ms long train was varied to generate peak force equal to … Therefore, excitability of a tissue is commonly characterized by a strength-duration … The specific impact is reflected in a reduced upward pressure of the tongue on the palate during swallowing. Finally, the dB change in current per doubling of pulse duration for threshold and equally loud stimuli was calculated for nine subjects (52 electrodes). During this time, the pulse duration increases from 120 μs to 300 μs. NIH According to the type of patient and personnel protection from current stroke this electrical stimulator corresponds to class 1; working voltage – safe ultra low-voltage (according to GOST R 50267.0-92) Be careful during application of the electrical … Loudness summation for pulsatile electrical stimulation of the cochlea: effects of rate, electrode separation, level, and mode of stimulation. 30 minutes is probably the minimal effective time, but it can be delivered for as long as needed. Clipboard, Search History, and several other advanced features are temporarily unavailable. J Assoc Res Otolaryngol. Very short pulses, between 10 and 50 JUS seemed prefer­ able because of a better ability to differentiate the sensory from the mo­ tor and painful stimulation. a plateau at a high level of stimulation. Mean lingual-palatal pressure integrals (mmHg) across different TES conditions. Alon et al back in 1983 showed that motor stimulation could be achieved with pulse durations in the range of 20 to 200 microseconds, … Mean lingual-palatal peak pressures (mmHg)…. Thirty healthy older adults (60-70 years of age) participated in this study. Mean lingual-palatal pressure integrals (mmHg)…. Would you like email updates of new search results? Adenis V, Gourévitch B, Mamelle E, Recugnat M, Stahl P, Gnansia D, Nguyen Y, Edeline JM. This result was hypothesized to be due to a relationship between the neural charging characteristics and the distance of the excited neural elements from the electrode. 10, 30, 100, 300ms and constant current. E-stim unit with rectangular waveform with pulse duration i.e. LFS parameters consisted of a low frequency biphasic charge-balanced stimulation waveform; pulse width 2 ms, with intensity ranging from 0.5 to 5 mA. 2001 Sep;110(3 Pt 1):1514-24. doi: 10.1121/1.1394222. 2015 Jun;16(3):401-12. doi: 10.1007/s10162-015-0511-2.
