“…Although the reliability of frequency-domain measures for postural sway, particularly mean and median power frequencies, are known to be lower than time-domain measures (Lafond et al 2004;Lin et al 2009), the reliability of quantifying force fluctuation measures, in either the time or frequency domains, have remained uninvestigated. Both the intra-and intersession reliabilities of the test measures in 16 subjects in this study were found to be excellent in the time domain.…”

This study investigated the hypothesis that fatiguing exercises led to increased force fluctuations during submaximal isometric knee extensions and to decreased accuracy and steadiness in the time and frequency domains. Sixteen young adults (eight males, eight females) were tested, in a seated posture with 90°knee flexion, to assess their ability to reproduce target extensor torques set at 15 per cent and 20 per cent of their maximum voluntary isometric contraction, both before and after fatiguing exercises. Normalized mean (NMAE) and peak (NPAE) of the absolute error were both used to quantify accuracy, whereas normalized standard deviation of the absolute error (NSAE) was used to quantify steadiness of the torque trials in the time domain. Mean and median power frequencies (MnPF, MdPF) and normalized peak power (NPkP) were used to assess the spectral structure of the torque signals. NMAE, NSAE and NPAE all showed excellent intra-as well as intersession reliabilities (intraclass correlation values greater than 0.75 and low standard error of measurement values), demonstrating repeatability of the test set-up. NMAE, NSAE and NPAE increased significantly postfatigue (greater than 42%), together with a shift towards higher frequency (MnPF and MdPF) components, indicating that the set-up was sensitive enough to detect the decreased force accuracy and steadiness of the musculature after fatigue. Increased force variability in both the time and frequency domains could therefore explain decreased steadiness after fatigue.

“…The task of maintaining upright balance is a critical component in performing most daily activities. Numerous studies [2][3][4][5][6][7][8][9][10][11][12][13][14][15] have investigated the effects of muscular fatigue on the regulation of bipedal quiet upright standing. Generally, a deterioration of postural control with muscular fatigue was reported.…”

“…Most of the investigations cited above referred to postural control following lower limb efforts or general body fatigue. In recent years, a growing number of studies have reported increased postural sway during quiet standing with muscle fatigue localized at the lower back [7][8][9][10][11][12][13][14][15]. All of these studies assessed postural stability using laboratory measures such as a force platform; however evidence using clinical measures of postural stability is lacking.…”

Objective: To determine the effect of trunk extensor muscle fatigue on postural stability in healthy young adults using clinical measures Conclusions:Trunk extensor fatigue significantly affects static and dynamic postural stability in healthy young adults. Complete recovery takes 12.5+3.27 minutes for static and 11.93+3.22 minutes for dynamic postural stability. Results of this study stress the importance of intact trunk extensor muscle function on the regulation of static and dynamic postural stability in healthy young adults. However, more studies are required to determine the effect of trunk extensor muscle fatigue using other clinical measures and in individuals with neuromuscular disorders.

“…This result is consistent with findings from numerous studies of participants who displayed impaired static and dynamic balance in a fatigued state. Several postural-control measures were studied in these trials, such as sway velocity, horizontal and sagittal sway magnitude, 18,32 the SEBT, 20 and the TTS. 19 Consistent negative effects on static and dynamic balance abilities were reported after local muscle and whole-body fatiguing exercise.…”

Context: Sensorimotor control is impaired after ankle injury and in fatigued conditions. However, little is known about fatigue-induced alterations of postural control in athletes who have experienced an ankle sprain in the past.Objective: To investigate the effect of fatiguing exercise on static and dynamic balance abilities in athletes who have successfully returned to preinjury levels of sport activity after an ankle sprain.Design: Cohort study. Setting: University sport science research laboratory.Patients or Other Participants: 30 active athletes, 14 with a previous severe ankle sprain (return to sport activity 6-36 months before study entry; no residual symptoms or subjective instability) and 16 uninjured controls.Intervention(s): Fatiguing treadmill running in 2 experimental sessions to assess dependent measures.Main Outcome Measure(s): Center-of-pressure sway velocity in single-legged stance and time to stabilization (TTS) after a unilateral jump-landing task (session 1) and maximum reach distance in the Star Excursion Balance Test (SEBT) (session 2) were assessed before and immediately after a fatiguing treadmill exercise. A 2-factorial linear mixed model was specified for each of the main outcomes, and effect sizes (ESs) were calculated as Cohen d.Results: In the unfatigued condition, between-groups differences existed only for the anterior-posterior TTS (P ¼ .05, ES ¼ 0.39). Group-by-fatigue interactions were found for mean SEBT (P ¼ .03, ES ¼ 0.43) and anterior-posterior TTS (P ¼ .02, ES ¼ 0.48). Prefatigue versus postfatigue SEBT and TTS differences were greater in previously injured athletes, whereas static sway velocity increased similarly in both groups.Conclusions: Fatiguing running significantly affected static and dynamic postural control in participants with a history of ankle sprain. Fatigue-induced alterations of dynamic postural control were greater in athletes with a previous ankle sprain. Thus, even after successful return to competition, ongoing deficits in sensorimotor control may contribute to the enhanced ankle reinjury risk.Key Words: sensorimotor control, neuromuscular activity, copers, balance, time to stabilization, Star Excursion Balance Test Key PointsWhen athletes were tested in the unfatigued state, only minimal differences in postural control were detected between athletes who had fully recovered from an ankle sprain and uninjured controls. Injured participants experienced larger fatigue-induced alterations of dynamic postural control than healthy controls. Persistent sensorimotor control deficits in recovered athletes might remain undetected in the unfatigued state.
