“…Nakano et al demonstrated that female patients in their 70s show a significant decline in functionality, i.e., physical performance and balance, as compared to their male peers. Older females display greater loss of muscle mass and muscle strength, which predisposes to frailty syndrome18 ) . Duckham et al showed that males over 65 had significantly greater rates of outdoor falls while engaging in recreational or vigorous activities.…”

[Purpose] The risk of falls in the elderly is an important public health problem. Suitable tests may help detect those at risk of falling. This study determined which balance test for older adults generates the most reliable results in terms of fall risk assessment, based on the number of falls over the last 12 months. [Subjects and Methods] A total of 153 individuals (31 males, 122 females, aged 76.67 ± 8.3 years; median 76.5, range 65–94) were investigated. The subjects were subdivided between fallers (a fall over the last 12 months) and non-fallers (no falls over the last 12 months). All participants were assessed with the following: Barthel Scale, Mini-Mental State Examination, Timed Up and Go, Tinetti Performance-Oriented Mobility Assessment), Berg Balance Test, and One-Legged Stance Test. [Results] Statistically significant differences were detected between fallers and non-fallers in TUG, POMA, BBS, and OLST scores. The number of falls correlated positively with the results for TUG, POMA, and OLST. [Conclusion] TUG and POMA were the most useful screening tests for balance and gait impairment in elderly nursing home residents. Two or more tests should be performed for more precise assessment of the risk of falling.

“…SPPB was used to evaluate the performance of lower limbs in three aspects: muscle strength, gait and balance [30]. The test consisted of three small tests: the first assesses static balance in three positions (the feet together in side-by-side, semi-tandem and tandem positions); the second assesses gait speed, timing how long it takes to go three meters at a normal pace; the third evaluates the strength of the lower limbs, clocking time to rise from a chair and return to the seated After the experimental period, the intragroup evaluation demonstrated a significant increase of 26.6% (PG) and 40.3% (AG) in the distance walked in 6MWT (p = 0.001).…”

Licensed under a Creative Commons attribution ORIGINAL ARTICLE [T] Photobiomodulation and physical exercise on strength, balance and functionality of elderly women Abstract Introduction: Aging is associated with structural changes in muscle tissue, which leads to the loss of functional independence. The preservation of the muscle strength through strength training, and recently, low-level laser therapy (LLLT), has high clinical significance. Objective: to investigate the effects of photobiomodulation (PBM -808 nm, 100 mW, 35.7 W/cm 2 and 7 J) associated with a strength training program on quadriceps muscle strength, balance and functional capacity in elderly women. Methods: Thirty-five healthy women between 60 to 70 years old were divided into two groups: Placebo Group (n = 13) and Active Group (n = 14). The exercise protocol consisted of knee flexion-extension exercise followed by application of PBM placebo or active, twice a week for 8 consecutive weeks.

The strength training program associated with PBM active improved a significant increase, relative to baseline, to the right medial/lateral stability index (p = 0.007) and decrease in the Fall Risk Test (p = 0.005). Conclusion: the strength training produced a significant increase of muscle strength and functionality and when combined with the PMB it was significant in the improvement of postural stability and decrease of fall risk.

“…Aging is associated with a decline in mobility and balance, which may lead to falls and a loss of independent function [1]. One possible mechanism of these impairments in older adults is an increase in lower extremity muscle co-contraction.…”

Older adults often exhibit high levels of lower extremity muscle co-contraction, which may be the cause or effect of age-related impairments in gait and associated falls. Normal gait requires intact executive function and thus can be slowed by challenging executive resources available to the neuromuscular system through the performance of a dual task. We therefore investigated associations between lower limb co-contraction and gait characteristics under normal and dual task conditions in healthy older adults (85.4±5.9 years). We hypothesized that greater co-contraction is associated with slower gait speed during dual task conditions that stress executive and attentional abilities. Co-contraction was quantified during different phases of the gait cycle using surface electromyography (EMG) signals obtained from the anterior tibialis and lateral gastrocnemius while walking at preferred speed during normal and dual task conditions. Variables included the time difference to complete the Trail Making Test A and B (ΔTMT) and gait measures during normal or dual task walking. Higher co-contraction levels during the swing phase of both normal and dual task walking were associated with longer ΔTMT (normal: R2=0.25, p=0.02; dual task: R2=0.27, p=0.01). Co-contraction was associated with gait measures during dual task walking only; greater co-contraction levels during stride and stance were associated with slower gait speed (stride: R2=0.38, p=0.04; stance: R2=0.38, p=0.04), and greater co-contraction during stride was associated with longer stride time (R2=0.16, p=0.03). Our results suggest that relatively high lower limb co-contraction may explain some of the mobility impairments associated with the conduct of executive tasks in older adults.
