Effects of unilateral leg muscle fatigue on balance control in perturbed and unperturbed gait in healthy elderly

Abstract: This study assessed effects of unilateral leg muscle fatigue (ULMF) on balance control in gait during the stance and swing phases of the fatigued leg in healthy elderly, to test the assumption that leg muscle strength limits balance control during the stance-phase. Ten subjects (aged 63.4, SD 5.5 years) walked on a treadmill in 4 conditions: unperturbed unfatigued, unperturbed fatigued, perturbed unfatigued, and perturbed fatigued. The perturbations were lateral trunk pulls just before contralateral heel conta… Show more

“…Another practical relevance was that increased medio-lateral trunk movement asymmetry was significantly associated with quadriceps strength asymmetry, even after adjustment for covariates, including bilateral knee pain and bilateral radiographic knee OA, which have been suggested to be significant factors associated with trunk movement asymmetry 4,5 . Our observations generally support the previous finding that strength asymmetry in older women is associated with increased gait asymmetry and variability 16 , although this does not support previous studies demonstrating that physically fatigued lower limb muscles in older adults resulted in decreased interstride medio-lateral trunk acceleration variability 39 and balance control 45 . Our findings imply that mediolateral trunk movement asymmetry increases quadriceps strength asymmetry, or vice versa, although the study's cross-sectional nature limits our interpretations about causality.…”

“…the increased sensory-motor noise) due to fatigue. Toebes and co-workers also did not find significant effects of unilateral knee extensor muscle fatigue on gait stability although the initial mechanical resistance against perturbations in the ML direction was reduced [22]. Apparently, all of our fit and healthy participants [23] were able to use compensatory strategies to control their gait stability, irrespective of unilateral hip abductor muscle fatigue.…”

“…In healthy young and older adults (who are not affected by confounding factors from neurological disorders), lower muscle strength and muscle fatigue have been shown to affect both balance and gait performance (the latter including a decreased velocity, stride length, and gait stability). [43][44][45][46] In hemiparetic stroke patients, weakness of the affected leg has been identified as one of the most important predictors of balance disability and abnormal gait, independently of other factors related to stroke pathology. 18,19 Specifically, lower strength in the most affected leg may cause a smaller range of motion and thereby promote a more asymmetric gait.…”
