Falls from heights resulting from a loss of balance are a major concern in the occupational setting. Previous studies have documented a deleterious effect of lower extremity fatigue on balance. The purpose of this study was to investigate the effect of lumbar extensor fatigue on balance during quiet standing. Additionally, the effects of fatigue rate on balance and balance recovery rate were assessed. Eight center-of-pressure-based measures of postural sway were collected from 13 participants… 
Effect of trunk extensor fatigue on the postural balance of elderly and young adults during unipodal task
A significant effect of trunk extensor muscle fatigue on postural control was demonstrated, which was more evident in young adults than in the elderly, as well as to determine the time necessary to recover posture control after fatigue.
Acute effects of localized muscle fatigue on postural control and patterns of recovery during upright stance: influence of fatigue location and age
Recovery of postural control post-fatigue was influenced by age, being more rapid in the younger group, but not by fatigue location, which may facilitate the development of strategies to prevent occupational falls.
Postural strategy changes with fatigue of the lumbar extensor muscles.
Fatigue influences the dynamic stability of the torso
The findings reported here indicate that one mechanism by which fatigue contributes to low back disorders may be spinal instability, and this information may contribute to the development of ergonomic countermeasures to help preventLow back disorders.
Effect of lumbar extensor fatigue on paraspinal muscle reflexes.
Effect of Trunk Extensor Muscle Fatigue on Postural Stability in Healthy YoungAdults
The importance of intact trunk extensor muscle function on the regulation of static and dynamic postural stability in healthy young adults is stressed, however, more studies are required to determine the effect of trunkextensor muscle fatigue using other clinical measures and in individuals with neuromuscular disorders.
The association of reactive balance control and spinal curvature under lumbar muscle fatigue
It is indicated that lumbar muscle fatigue causes changes in the lumbr spinal curvature and this is functionally relevant in explaining the impaired ability to maintain balance after externally induced perturbations.


Effects of isokinetic ankle fatigue on the maintenance of balance and postural limits.
Isokinetic fatigue of ankle plantarflexors and dorsiflexors significantly influences sway parameters and ranges of postural control in healthy young men.
The effect of fatigue on multijoint kinematics, coordination, and postural stability during a repetitive lifting test.
Measurements of endurance, kinematics, postural stability, and coordination, in addition to strength, are necessary to fully document the patients' functional capabilities to guide physical therapists in their rehabilitation of low back pain patients.
Effect of lower extremity muscular fatigue on motor control performance.
The findings support anecdotal evidence that fatigued individuals are at increased risk of injury because of loss of balance and avoidance of fatigue and preconditioning may prevent injury.
The effects of fatigue, with and without rehydration, on postural control in 10 healthy subjects who regularly practice sports activities suggest that fatigue mainly alters muscular effectors and sensory inputs, such as proprioception, resulting in poor postural regulation.
Fatigue effects on body balance.
The effect of lumbar fatigue on the ability to sense a change in lumbar position. A controlled study.
This study finds that there seems to be a period after a fatiguing task during which the available information on lumbar position and its changes is inaccurate, and patients with low back trouble had poorer ability to sense a change in lumbAR position than control subjects even when they were not fatigued.
Effects of Fatigue on Knee Proprioception
It is suggested that exercising to fatigue may produce a change in subjects' reproduction ability of knee joint angles, which may represent a decline in proprioceptive function after heavy exercise bouts.
Postural stability is compromised by fatiguing overhead work.

It is argued that fatigue plays a more important role than simple task duration in causing the observed increases in sway, and hence decreases in postural stability.
