Relationship between cognition and gait performance in older adults receiving physical therapy interventions in the home

Comorbidities, medications, depression, and physical performance measures associated with severe cognitive impairments in community-dwelling adults

Cognitive impairment negatively impacts health, psychological, social, and economic domains. Cognitive impairment commonly affects physical functions in older adults, whereas these are deteriorated. However, the prevalence and associated factors of cognitive impairment among community-dwelling adults in Saudi Arabia have not been investigated yet. This study aimed to examine the prevalence of severe cognitive impairment and its associated factors in community-dwelling older adults in Saudi Arabia. This cross-sectional study involved adults aged ≥50 years. Demographic data and clinical data, including number of medications and body mass index (BMI), were collected. Cognitive impairment and depressive symptoms were measured using Arabic versions of the Montreal Cognitive Assessment (MoCA) and Patient Health Questionnaire-9 (PHQ-9), respectively. The participants were divided into severe cognitive impairment and mild cognitive impairment or normal cognitive function groups based on a score of <20 or ≥20, respectively, using the MoCA. Physical measures included dynamic gait index (DGI) scores, timed up-and-go (TUG), 5 times sit-to-stand (5XSST), functional reach test, and 6-minute walk test. A total of 206 participants (female: n = 96) were included. The prevalence of severe cognitive impairment in the community-dwelling older adults was 12.6%. The number of chronic conditions (odds ratio [OR]: 2.31, p<0.001), number of medications (OR: 1.36, p = 0.003), and depressive symptoms using PHQ-9 (OR: 1.11, p = 0.009) were significantly associated with severe cognitive impairment after adjustment for other covariates, including age, sex, and BMI. Based on the physical function measures, only the scores for DGI (OR: 0.86, p = 0.003), TUG (OR: 1.16, p = 0.035) and 5XSST (OR: 1.25, p <0.001) were significantly associated with severe cognitive impairment. This study revealed a high prevalence of severe cognitive impairment among community-dwelling adults in Saudi Arabia. Its major risk factors include depressive symptoms, number of chronic conditions and medications, and physical measures, including DGI, TUG, and 5XSST.

A Multidimensional Exercise Program in the Home for Older Adults Designed to Improve Function

The purpose of this study was to determine whether there was difference in the OASIS (Outcome and Assessment Information Set) activities of daily living (ADL) items scores between the Safe Strides program and Safe Strides plus Zōntago program. Eight home care offices were selected for this prospective randomized quality improvement study where Safe Strides versus Safe Strides plus Zōntago were compared. Rehabilitation outcome OASIS ADL change scores were analyzed for 112 total patient care episodes. The Safe Strides + Zōntago mean total ADL score change and ADL change per visit were higher than the Safe Strides group. Differences in ADL outcomes in older adults undergoing home care provided by physical therapists and physical therapist assistants in the Safe Strides exercise program versus the Safe Strides plus Zōntago program were noted. The Safe Strides + Zōntago compared with Safe Strides alone improved patient functional outcomes as measured by the OASIS.

Multiple diabetic complications, as well as impaired physical and mental function, are associated with declining balance function in older persons with diabetes mellitus

OBJECTIVE

To investigate whether there is a difference in balance function between older persons with and without diabetes mellitus (DM), and to identify whether mediating factors, such as diabetic complications, Instrumental Activities of Daily Living (IADL) score, Mini-Mental State Examination (MMSE) score, as well as hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein (LDL), are associated with balance function in older persons with DM.

METHODS

In this cross-sectional study, a total of 208 older persons were divided into a DM group (n=80) and a control group who did not have DM (n=128). Balance function was evaluated with the Tinetti performance-oriented mobility assessment (POMA), which includes balance and gait subscales. Activities of daily living (ADL), IADL, and the MMSE were also measured. Fall incidents in last 12 months, the use of walking aids, fear of falling, comorbidities, and polypharmacy were recorded. Diabetic complications were recorded, and HbA1c, FPG, TC, TG, and LDL were measured in the patients of the DM group.

RESULTS

Fall incidents in last 12 months were higher in the DM group than in the control group (P<0.01). POMA score as well as ADL and IADL scores were lower in the diabetic group than the control group (P<0.05). Within the diabetic group, the POMA score was positively related to the ADL score (odds ratio [OR], 11.7; 95% confidence interval [CI], 3.076-44.497; P<0.01), IADL score (OR, 16.286; 95% CI, 4.793-55.333; P<0.01), and MMSE score (OR, 10.524; 95% CI, 2.764-40.074; P<0.01), but was negatively related to age (OR, 7.707; 95% CI, 2.035-29.185; P<0.01) and diabetic complication (OR, 6.667; 95% CI, 2.279-19.504; P<0.01). Also, within the DM group, the decreased POMA score was associated with multiple diabetic complications (OR, 5.977; 95% CI, 1.378-25.926; P<0.05), decreased IADL score (OR, 10.288; 95% CI, 2.410-43.915; P<0.01), and MMSE score (OR, 13.757; 95% CI, 2.556-74.048; P<0.01).

CONCLUSION

Multiple diabetic complications, lower MMSE, ADL, and IADL scores were associated with declining balance function in the older persons with DM. These findings can alert physicians to detect and intervene earlier on declining balance in older persons with DM.
