“…Falls of all types are more likely to occur in older adults with cognitive impairments, as has been observed in a cross-sectional study (Hong et al, 2010). The Mini Mental State Examination (MMSE; Folstein et al, 1975) is one of the most common assessment tools for global cognition.…”

Falls, a common cause of injury among older adults, have become increasingly prevalent. As the world’s population ages, the increase in—and the prevalence of—falls among older people makes this a serious and compelling societal and healthcare issue. Physical weakness is a critical predictor in falling. While considerable research has examined this relationship, comprehensive reviews of neuropsychological predictors of falls have been lacking. In this paper, we examine and discuss current studies of the neuropsychological predictors of falls in older adults, as related to sporting and non-sporting contexts. By integrating the existing evidence, we propose that brain aging is an important precursor of the increased risk of falls in older adults. Brain aging disrupts the neural integrity of motor outputs and reduces neuropsychological abilities. Older adults may shift from unconscious movement control to more conscious or attentive motor control. Increased understanding of the causes of falls will afford opportunities to reduce their incidence, reduce consequent injuries, improve overall well-being and quality of life, and possibly to prolong life.

“…Falls constitute a serious issue for physical therapists, physicians and physical educators because it negatively impacts the quality of life and reduces independent living in older adults [1]. The etiology of falls in older adults is multifactorial and the knowledge of biomechanical and physiological factors involved has important clinical application [2].…”

BACKGROUND: Hip muscles dysfunction may challenge postural control mechanisms and compromise the individual in imbalance situations. OBJECTIVE: To compare hip muscles strength, power and activation between older female fallers and non-fallers. METHODS: Forty-four older adult women (60-85 yr) were divided into two groups based on having falling or not in the period of one year before evaluation, fallers (n = 20) and non-fallers (n = 24). Isokinetic strength and power were assessed during hip flexion, extension, abduction and adduction movements, while EMG signals were recorded from the internal oblique (IO), rectus femoris (RF), multifidus (MU), gluteus maximum (GM), and biceps femoris (BF). RESULTS: Fallers had significantly lower extension (p = 0.033), abduction (p = 0.001) and adduction (p = 0.002) strength as well as significantly lower power in hip flexion (p = 0.028), extension (p = 0.005) and abduction (p = 0.002) compared to non-fallers. Non-fallers had 27.4% greater activation of RF (p = 0.005) during hip flexion and 37.9% higher coactivation of IO/MU during hip abduction (p = 0.003). Significant linear regression was found between hip extension strength and GM and BF activation in both groups. CONCLUSION: Hip muscles strength and activation may increase the risk of falling in older women.

“…This is reflected by the following studies. Hong et al (2010) investigated the correlation between hand grip strength and falls among elderly Koreans, whereas Auyeung et al (2011) studied the correlation between hand grip strength and the decrease in cognitive ability. Sasaki et al (2007) studied the increase in mortality among middle-aged Japanese men and women.…”
