The effect of walking path configuration on gait in adults with Alzheimer’s dementia

BackgroundWalking is a cognition intensive activity and impaired walking is associated with an increased fall risk in people with Alzheimer’s dementia (AD). Walking in a curved path configuration increases complexity of the task, reflects real-life environments and situations when falls occur. The effect of walking path task complexity has not been evaluated in people with AD.Research questionThe purpose was 1) to assess the utility of a curved path walking task to detect differences in gait performance between people with AD and healthy controls and 2) to assess the relationship of cognitive function to gait performance on straight path and curved path walking.MethodsParticipants with AD (n = 14, mean age ± SD = 73.08 ± 9.22) and age and sex matched controls (n = 14, mean age = 72.86 ± 9.53) were recruited. Time to complete a 6-meter straight path and a curved path (Figure of 8 Test) walking task was recorded. Steps taken, accuracy and qualitative measures of smoothness were rated for curved-path walking. Measures of global cognition (MMSE, MoCA) and executive function (Trail making A and B, Digit Span forwards and backwards) were assessed.ResultsGait was significantly slower in people with AD for both the straight-path (AD = 6.05 ± 1.26 s, Control = 5.09 ± 0.76 s, p = 0.02) and curved-path walking (AD = 11.25 ± 4.87 s, Control = 8.28 ± 2.44 s, p =  0.05). In addition, smoothness scores were significantly lower for people with AD (AD = 1.93±1.26; Control = 3.00±0.00, p = 0.004).SignificanceWalking in a curved path resulted in a significant deterioration in gait quality in the people with AD. Executive function was related only to curved path walking, in which lower executive function scores were associated with longer time to walk.

Effects of Interventions That Include Aided Augmentative and Alternative Communication Input on the Communication of Individuals With Complex Communication Needs: A Meta-Analysis

Purpose

The purpose of this meta-analysis was to investigate the effects of augmentative and alternative communication (AAC) interventions that included aided AAC input (e.g., aided AAC modeling, aided language modeling, aided language stimulation, augmented input) on communicative outcomes (both comprehension and expression) for individuals with developmental disabilities who use AAC.

Method

A systematic search resulted in the identification of 26 single-case experimental designs (88 participants) and 2 group experimental designs (103 participants). Studies were coded in terms of participants, intervention characteristics, dependent variables, outcomes, and quality of evidence.

Results

AAC interventions that included aided AAC input in isolation, or as part of a multicomponent intervention, were found to be highly effective across participants of various ages, disabilities, and language skills. The interventions typically included aided AAC input in conjunction with expectant delay, direct prompting (e.g., spoken, gestural), contingent responding, and open-ended questions. The interventions were found to be highly effective in supporting both comprehension and expression across the domains of pragmatics, semantics, and morphosyntax. Outcomes related to expression were reported more often than outcomes related to comprehension.

Conclusion

Aided AAC input may reduce input–output asymmetry and enhance expression and comprehension for individuals who use AAC; the evidence suggests that partners should utilize this strategy. Future research is needed to investigate the effects of AAC input (aided and unaided) on long-term language development for individuals who require AAC.
