“…With advancing age, intrinsic structural, and functional involutions in myotendinous and articular systems characterized by loss of muscle mass, weakening of contractility, a reduction in tendinous and muscle stiffness, the alteration of intermuscular coordination (agonist-antagonist muscle co-contraction) and a decrease in the range of motion of eversion-inversion of the foot (Vandervoort, 2002 ; Menz, 2015 ) inevitably contribute to lessening the motor output of the postural function (Bok et al, 2013 ; Cattagni et al, 2014 ; Menz, 2015 ). Based on these involutions, for a given postural condition, the effort required to ensure body balance necessarily increases (Skurvidas et al, 2012 ). Older subjects need more electromyographic activity (EMG) than young subjects to produce adequate torque to stabilize posture (Billot et al, 2010 ).…”

Although motor output of the postural function clearly influences postural performance in young and older subjects, no relationship has been formally established between them. However, the relationship between lower-extremity muscle strength/power and postural performance is often pointed out, especially in older subjects. In fact, the influence of motor output may vary according to the postural condition considered (e.g., static, dynamic, challenging, disturbing). In static postural condition, there may be a relationship between lower-extremity muscle strength and postural performance when the value of muscle strength is below a certain threshold in older subjects. Above this threshold of muscle strength, this relationship may disappear. In dynamic postural condition, lower-extremity muscle power could facilitate compensatory postural actions, limiting induced body imbalance likely to generate falls in older subjects. In young subjects, there could be a relationship between very early rapid torque of the leg extensor muscles and postural performance. In the case of postural reaction to (external) perturbations, a high percentage of type II muscle fibers could be associated with the ability to react quickly to postural perturbations in young subjects, while it may enable a reduction in the risk of falls in older subjects. In practice, in older subjects, muscle strength and/or power training contributes to reducing the risk of falls, as well as slowing down the involution of muscle typology regarding type II muscle fibers.

The Mediolateral CoP Parameters can Differentiate the Fallers among the Community-dwelling Elderly Population

[Purpose] Age-related mediolateral (ML) instability of static postural control in the elderly has been well studied. Recent studies have provided evidence that ML center of pressure (CoP) parameters during dynamic postural control are more sensitive for differentiation of the fallers in the elderly. However, very limited studies have been done in which ML stability differences between fallers and non-fallers were investigated. The purpose of this study was to investigate the differences in ML CoP parameters between elderly fallers and elderly non-fallers during dynamic postural control. [Subjects and Methods] Twenty-nine community-dwelling older adults were divided into either fallers or non-fallers according to a self-report related to falling history within a year. Every participant performed 4 different tasks (static postural control tasks comprising quiet stance with eyes open and eyes closed and dynamic postural control tasks comprising stance with arm lifting and with trunk flexion) on force plates. [Results] The fallers demonstrated decreased AP and ML CoP parameters, and ML CoP distance was significantly smaller than in the non-fallers during both dynamic postural control tasks. [Conclusions] ML CoP parameters were able to differentiate the fallers from the non-fallers in a community-dwelling elderly population.

StreszczenieWstęp: Prawidłowa równowaga jest funkcją warunkującą właściwie wykonywanie czynności z zakresu dnia codziennego. Związane z wiekiem osłabienie reakcji sensorycznych i ruchowych, może spowodować niestabilność postawy oraz zwiększone ryzyko upadków.Celem pracy jest określenie różnic w wartościach parametrów charakteryzujących równowagę kobiet po 60 roku życia.Materiał i metody: Do badań przystąpiło łącznie 180 kobiet: 98 kobiet w wieku od 60 do 92 lat (x= 71 lat) oraz 82 kobiety w wieku od 21 do 26 lat (x= 22 lata). Przy użyciu platformy stabilometrycznej, oceniono równowagę pozycji stojącej w próbie z oczami otwartymi oraz zamkniętymi. Oceniono 6 różnych parametrów ruchu środka nacisku stóp (COP).Wyniki: Analiza statystyczna wykazała istotne różnice w większości badanych parametrów równowagi kobiet po 60 roku życia w porównaniu do kobiet z grupy kontrolnej.Wnioski: 1) Wraz z wiekiem zachodzą istotne zmiany w procesie utrzymywania równowagi powodujące rosnący deficyt stabilności ciała. 2) Kobiety po 60 roku życia wykazują gorszą stabilność postawy niż kobiety młodsze w zakresie każdego analizowanego parametru z wyjątkiem wychyleń w płaszczyźnie czołowej. równowaga, środek nacisku stóp, wiek podeszłyAbstract Introduction: Correct balance is necessary ability to proper performance of activities of daily living. Age-related weakening of the sensory and motor reactions, can cause postural instability and increase risk of falls.Aim of this study is to determine the differences in the values of the parameters describing the postural stability of women over 60 years of age.Material and methods: 180 women participated in the study: 98 women between the age of 60 and 92 (x=71 years old) and 82 women between the age of 21 and 26 (x=21 years old). Standing balance was assessed in the trial with eyes open and closed, by using stabilometric platform. Six different motion parameters of center of pressure (COP) were evaluated.Results: Statistical analysis showed significant differences in most parameters of the balance of women over 60 years of age and women in the control group.Conclusions: 1) With age, there are significant changes in the in the balancing process, causing growing deficit of postural stability. 2) Women over age 60 have a worse postural stability than younger women within each analyzed parameter with the exception of swings in the frontal plane.balance, center of pressure, elderly justyna_wyszynska@o2.pl
