“…Although the base of gait can predict falls, correcting the walk habitat may be challenging in the elderly. The selection of proper footwear may assist the elderly in achieving better gait stability [30,31]. Footwear plays an essential role in postural and dynamic instability by facilitating somatosensory feedback to the foot [30,31].…”

Background: Falling is a major public health concern of elderly people. We aimed to determine if lean mass and spatiotemporal gait parameters could predict the risk of falling in elderly women and also study the relationships between lean mass and gait characteristics. Methods: Twenty-four community women were prospectively recruited (mean age, 72.30 ± 5.31 years). Lean mass was measured using dual-energy fan-beam X-ray absorptiometry. Gait characteristics were assessed using spatiotemporal analysis. Fall risks were assessed using the Berg Balance Scale (BBS) and the Falls Efficacy Scale-International. Fall histories were recorded. Appropriate statistical analyses were applied to determine lean mass and gait characteristics in predicting the risk of fall and the associations between lean mass and gait characteristics. Results: There were 14 participants (58.33%) with fall histories. Patients with fall histories had a significantly narrower base of support and lower BBS score. However, only the base of support was significantly associated with fall risk (odds ratio, 0.415; p = 0.022). Lean mass was significantly negatively associated with proportion of swing phase and positively associated with proportions of stance and double-support phases. Conclusion: Fall risk among elderly women can be predicted using base of support, where a narrower base predicts a greater fall risk. Although the lean mass was not related to risk of fall, lean mass is still related to some gait characteristics.

“…Figure 2 displays the ROCs of gait variables associated with BMD as demonstrated in this study (LI), and walking speed and cadence, which have previously been shown to be a potential parameter associated with low BMD [4,13]. The ROCs of LI, cadence, and walk speed in predicting low BMD were significantly associated with LI [AUC (area under the curve) of 0.75±0.10 (mean ± standard error), 95% confidence interval (CI): 0.55–0.95; P =0.031], but not with cadence (AUC of 0.70±0.10, CI: 0.50–0.91, P =0.080) or walking speed (AUC=0.5±0.11, CI: 0.27–0.73, P ≥0.05).…”

“…During the course of aging, postmenopausal women are more susceptible to osteoporosis due to related hypoestrogenism [2]. Such elderly women tend to show reductions in muscle mass and strength, which may affect gait patterns [3,4]. A recent kinetic study demonstrated decreased external hip extension and adduction moments, power generation at the hip and ankle, or hip and knee in postmenopausal women with low BMD compared to normal BMD subjects [5].…”

Assessment of Gait Symmetry in Elderly Women with Low Bone Mineral Density Using a Portable Trunk Accelerometer: A Pilot Study

BackgroundConvincing evidence regarding gait and balance function in elderly women with low bone mineral density (BMD) and/or osteoporosis is limited. In the present study, we aimed to compare the gait characteristics in elderly women with and without low BMD and to analyze plausible parameter(s) for predicting low BMD.Material/MethodsWe retrospectively analyzed prospectively collected data of 26 consecutive postmenopausal women aged >65 years who were admitted to our geriatric outpatient service. They were assigned to 2 groups, with (n=14) and without (n=12) low BMD based on T-score (<−1 standard deviation of the mean for healthy adults) of dual-energy X-ray absorptiometry. We compared gait parameters derived from a portable Tri-Axial trunk accelerometer that included cadence, walking speed, average acceleration, horizontal/vertical displacement ratio, and symmetry index of the Lissajous figure (LI) during a 5-meter walk test at comfortably fast speed between groups.ResultsWomen with low BMD tended to show increased LI compared with healthy subjects (P=0.04). No statistically significant differences were noted in cadence, walking speed, average acceleration, and ratio of horizontal and vertical displacement (P>0.05). Receiver operating characteristic curve analysis demonstrated that LI can predict low BMD in the femur neck with moderate accuracy (area under the curve=0.75, 95% confidence interval 0.55–0.95; P=0.031). The optimal cut-off value was 17%, with 67% specificity and 86% sensitivity.ConclusionsThese results suggest that elderly women with low BMD may walk with asymmetrical trunk movement, but they are able to generate gait patterns similar to healthy peers. The LI may provide valuable quantitative information for preventing fractures in subjects with osteoporosis.

“…Our results regarding gait speed were similar to those stated by Lindsey et al [37], who reported an association between gait speed and bone mineral density (BMD). Dostanpor et al [38] also suggested that gait speed was associated with low BMD or aging. This association implies that BMD management can also be an important factor in the rehabilitation process of patients with hip fracture.…”

ObjectiveTo determine post-operative physical performance factors associated with gait speed in patients surgically treated for hip fracture.MethodsCross-sectional data from 59 patients (16 males and 43 females; mean age, 79.2±9.1 years) who underwent hip fracture surgery were enrolled. Patients completed a 10-meter walk test (10MWT) to assess gait speed. Additional physical performance tests included the Timed Up and Go test (TUG), the Berg Balance Scale (BBS), maximum voluntary isometric contraction (MVIC) of the knee extensors and flexors on the operated and non-operated sides as well as of the hip abductors (all tested using air-resistance weight machines), and analysis of spatio-temporal gait parameters at about 6 weeks after hip surgery.ResultsBivariate analyses revealed a significant positive correlation between the post-operative 10MWT and the post-operative TUG, age, swing phase duration, and gait cycle duration along with a significant negative correlation between post-operative BBS score, MVIC of the knee extensors and flexors on the operated and non-operated sides, MVIC of the hip abductors, and cadence and stance phase duration. Linear regression analyses revealed that the post-operative TUG (β=0.85, p<0.01), gait cycle duration (β=0.17, p=0.02), and osteoporosis (β=-0.18, p=0.02) were associated with the post-operative 10MWT.ConclusionThe presence of osteoporosis, post-operative balance, and isometric muscle strength in the operated and non-operated legs were statistically associated with post-operative gait speed early after hip fracture surgery.
