An experiment was conducted to examine the effects of time uncertainty and instructed muscle tension on the reaction time of elbow flexion. Twenty‐two right‐handed subjects were asked to respond to an audio stimulus by flexing their right elbow under four conditions (2 time uncertainty × 2 instructed muscle tension). Electromyograms (EMGs) were recorded from the biceps and triceps on the subject's right side. Reaction time was divided into premotor time and motor time, based on the difference between the EMG and elbow flexion response. Analysis of reaction time showed that the effects of time uncertainty and instructed muscle tension were additive. Time uncertainty affected premotor time only, and instructed muscle tension affected motor time only. These results are discussed in terms of the assumption that premotor time is a reflection of the central nervous system and motor time is a reflection to the peripheral muscle system.

“…The patients with chronic ankle instability had been reported a delayed reaction time of peroneal muscles [ 42 ] and postural control deficits represented by increasing total excursion and area of the COP [ 43 ]. At neuromuscular, cellular, and molecular levels, FES training could significantly increase the fast-type myofibres' diameter of trained muscles and reduce the premotor reaction time by 18% [ 44 ]. It is crucial to note that a distinctive feature of electrical stimulation is the nonselective recruitment of fibres [ 40 ].…”

Functional Electrical Stimulation of Peroneal Muscles on Balance in Healthy Females

Balance improvement could contribute to ankle stability for the prevention of ankle sprains. Functional electrical stimulation (FES) is an effective way of augmenting muscle activity and improving balance. This study investigated the effect of FES of peroneal muscles on single-and double-leg balance. Fifteen healthy females (age=23.1±1.6 years, height=1.63±0.07 m, and weight=63.7±9.9 kg) performed single- and double-leg standing balance tests with eyes open and closed before and after 15-minute FES intervention during treadmill running at a comfortable, self-selected pace. FES of peroneal muscles was provided bilaterally, using an Odstock Dropped Foot Stimulator. The total excursion of the centre of pressure (COP) was calculated to assess the standing balance control ability. The total excursion of COP in single- and double-leg stance with eyes open reduced significantly after FES intervention by 14.7% (p<0.001) and 5.9% (p=0.031), respectively. The eyes-closed condition exhibited a 12.7% (p=0.002) reduction in single-leg stance but did not significantly change in double-leg stance (p>0.05). Limb preference did not account for balance postintervention. No significant difference in total excursion of COP was found between preferred and less preferred limbs with both visual conditions (p>0.05). FES of peroneal muscles improved standing balance control with eyes open in double-leg and single-leg stance and with eyes closed in double-leg stance. The improvements in balance control with FES treatment did not vary concerning limb preference.

“…Premotor time (time elapsed between the presentation of the stimulus and the activation of the muscle), Motor time (between the start of the muscular activity and the beginning of the action of the eff ector associated to the muscle; index fi nger for fi nger-lifting muscle and palm for the palm-lifting muscle) and Movement time (between the initiation of the action until the end of the action) were measured. Whereas the Premotor time refl ects the information processing time required to initiate the motor action, the Motor time is related to the working of the muscular system ( Weiss, 1965 ;Botwinick & Thompson, 1966a, 1966bLagassè & Hayes, 1973 ;Clarkson, 1978 ;Fluery & Lagassè, 1979 ;Sheridan, 1984 ) The criterion to determine Premotor times was an activation of 5 standard deviations above the interval mean (400 msec. before stimuli presentation), which remained above this threshold for at least 20 msec.…”

Use of different effectors in two consecutive actions could generate an attentional shift between the effectors with shorter latencies in the second action of reaching. 18 participants (10 men; M age = 21.3 yr.) participated in an experiment with two main variables: (1) effector switching with two levels (Switching and No Switching), where the participants use or do not use a different motor effector for each action; (2) lifting muscles, i.e., the muscles involved in the first phase of the reaching, with two levels (finger-lifting muscle and palm-lifting muscle). Premotor time, Motor time, Reaction time, Movement time, and Total time were measured. For Premotor, Movement, and Total times, faster responses were observed when there was no switching of the effector. This delay could be due to an attentional shift between motor effectors and its relations with motor processes. Possible applications include the ergonomic design of device controls, considering that the use of the same effector is beneficial when fast reaction times are sought.
