People with stroke are at risk for falls. The purpose of this study was to estimate the strength of the relationship of balance and mobility to falls.
The participants were 99 community-dwelling people with chronic stroke.
An interview was used to record fall history, and physical performance assessments were used to measure balance (Berg Balance Scale [BBS]) and mobility (gait speed).
No differences were found between subjects who fell once and subjects who did not fall or between subjects who fell more than once and subjects who did not fall. Neither balance nor mobility was able to explain falls in people with chronic stroke.
Clinicians should be cautious when using the BBS or gait speed to determine fall risk in this population. Falls occurred frequently during walking; it may be necessary to focus on reactive balance and environmental interaction when assessing individuals for risk of falls and devising fall prevention programs for individuals with chronic stroke. The authors' observations suggest that the prescription of 4-wheel walkers for individuals with a low BBS score (</=45) may be a mobility aid that could reduce the risk of falls.

    • "Stroke Research and Treatment to be high, ranging between 23–34%, 40–73%, and 43–70% during a 3-4 month [7] [16], 6-month [17] [18], and 1-year follow-up [19] [20], respectively. Most falls are reported to result from a trip, a slip, or a misplaced step while walking [17, 21–24] and walking is also the most frequently reported activity (39%–90%) at the time of a fall in stroke survivors [7] [17] [25] [26], suggesting the reduced ability of individuals with stroke to adjust walking to task and environmental demands. Despite the relevance of walking adaptability to everyday mobility and the reduced ability of individuals with stroke to adjust walking to task and environmental demands, assessment of walking adaptability has received relatively little attention.

    ABSTRACT: Control of walking has been described by a tripartite model consisting of stepping, equilibrium, and adaptability. This review focuses on walking adaptability, which is defined as the ability to modify walking to meet task goals and environmental demands. Walking adaptability is crucial to safe ambulation in the home and community environments and is often severely compromised after a stroke. Yet quantification of walking adaptability after stroke has received relatively little attention in the clinical setting. The objectives of this review were to examine the conceptual challenges for clinical measurement of walking adaptability and summarize the current state of clinical assessment for walking adaptability. We created nine domains of walking adaptability from dimensions of community mobility to address the conceptual challenges in measurement and reviewed performance-based clinical assessments of walking to determine if the assessments measure walking adaptability in these domains. Our literature review suggests the lack of a comprehensive well-tested clinical assessment tool for measuring walking adaptability. Accordingly, recommendations for the development of a comprehensive clinical assessment of walking adaptability after stroke have been presented. Such a clinical assessment will be essential for gauging recovery of walking adaptability with rehabilitation and for motivating novel strategies to enhance recovery of walking adaptability after stroke.

    ABSTRACT: Background. Poststroke impairment may lead to fall and unsafe functional performance. The underlying mechanism for the balance dysfunction is unclear. Objective. To analyze the relation between the motor level of the affected limbs and balance in poststroke subjects. Method. A prospective, cross-sectional, and nonexperimental design was conducted in a rehabilitation institute. A convenience sample of 44 patients was assessed for motor level using Brunnstrom recovery stage (BRS) and Fugl-Meyer Assessment: upper (FMA-UE) and lower extremities (FMA-LE). The balance was measured by Berg Balance Scale (BBS), Postural Assessment Scale for Stroke Patients (PASS), and Functional Reach Test (FRT). Results. BRS showed moderate correlation with BBS (ρ = 0.54 to 0.60; P < 0.001), PASS (r = 0.48 to 0.64; P < 0.001) and FRT (ρ = 0.48 to 0.59; P < 0.001). FMA-UE also exhibited moderate correlation with BBS (ρ = 0.59; P < 0.001) and PASS (ρ = 0.60; P < 0.001). FMA-LE showed fair correlation with BBS (ρ = 0.50; P = 0.001) and PASS (ρ = 0.50; P = 0.001). Conclusion. Motor control of the affected limbs plays an important role in balance. There is a moderate relation between the motor level of the upper and lower extremities and balance. The findings of the present study may be applied in poststroke rehabilitation.

    • "The BBS is an index developed by Berg and colleagues to assess overall balance ability in elderly people4), and its utility is widely recognized5, 6). The BBS has also been shown to be useful in assessing balance in patients with an acute stroke7), and there are reports on its relationship with maximum walking speed8) and functional walking ability9). Because the BBS consists of test items taken from specific ADLs, and the SBT is thought to be related to balance performance, there is a high likelihood that a significant correlation will be seen between these two tests.

    ABSTRACT: [Purpose] The purpose of this study was to analyze the relationship between results of the Berg Balance Scale (BBS) and Static Balance Test (SBT) in hemiplegic patients with stroke. [Subjects] The subjects were 39 hemiplegic patients (25 men, 14 women; mean age, 69.4 ± 11.0 years) with stroke that had occurred within the preceding 6 months and who had good understanding of verbal instructions. [Methods] The SBT consists of five posture-holding tasks (sitting, stride standing, close standing, one-foot standing on the unparalyzed leg, and one-foot standing on the paralyzed leg). Four grades, 1-4, are used to judge the ability of patients to hold these postures. The SBT and BBS were each implemented, and the relationship between test results was analyzed using correlation coefficients. [Results] The correlation coefficient for the BBS score and SBT score was 0.87. Thus, a strong correlation was seen between the BBS and SBT. [Conclusion] The SBT is thought to be an assessment index that can predict overall balance ability.
