RESUMEN
PURPOSE: We aimed to evaluate the relationship between the daily wheelchair self-propulsion distance and functional recovery in subacute stroke survivors. METHODS: Seventy-four patients with stroke were prospectively recruited from four convalescent rehabilitation hospitals. All participants were unable to walk independently and required manual wheelchairs for locomotion on admission. The daily wheelchair self-propulsion distance was measured using a cycle computer that was connected to a touch switch to exclude the assistance-propulsion distance. The outcome measures were represented as the relative gain of the Functional Independence Measure (FIM) effectiveness during hospitalization. Moreover, a better functional recovery was defined as a FIM effectiveness > 50%. Participants were categorized into three groups according to tertiles of the average daily wheelchair self-propulsion distance: lowest tertile (T1, ≤0.59 km/day); middle tertile (T2, 0.60-1.23 km/day); and highest tertile (T3, ≥1.24 km/day). RESULTS: Multivariate logistic regression analysis adjusted for baseline characteristics showed that the T2 and T3 groups had a significant association with better FIM effectiveness, and their odds ratios (95% confidence interval, p) were 7.26 (1.13-45.85, p = .038), and 10.19 (1.15-91.75, p = .035), respectively. CONCLUSIONS: The daily wheelchair self-propulsion distance was significantly associated with functional recovery in subacute stroke survivors.IMPLICATIONS FOR REHABILITATIONNon-ambulatory stroke survivors can obtain extra independent physical activity by using wheelchair self-propulsion, when they do not have someone to assist them with walking.This multicenter observational study revealed that the self-propulsion distance of a manual-wheelchair was significantly associated with functional recovery in subacute stroke survivors.

Objective: Although the propulsion distance of a wheelchair is measured by some devices, measuring self-propulsion distance, excluding assistance propulsion distance by the caregiver, is difficult. This is a pilot study conducted to verify whether the propulsion distance of wheelchair users, excluding the assistance propulsion distance, can be measured using a cycle computer by attaching the touch switch.Methods: The wheelchair propulsion distance was measured using a cycle computer. We connected the touch switch and the cycle computer to the wheelchair to exclude assistance propulsion distance. We set the cycle computer to stop recording while the caregiver was touching the sensor. To confirm the propulsion distance using the cycle computer, the volunteer propelled the wheelchair on a rectangular facility with a total distance of 181â m, and the examiner confirmed the propulsion distance. The validation test to confirm the accuracy of the touch switch attached to the cycle computer was performed on a 50-m straight runway. The volunteer and caregiver propelled the wheelchair alternately by 10â m and continued until 50â m. The examiner confirmed the distance after 50-m propulsion.Results: In the 181-m rectangular facility, the propulsion distance that the volunteer propelled the wheelchair with the cycle computer was 180â m. In the 50-m straight runway, the propulsion distance was 30â m with caregiver assistance for 20â m.Conclusion: The present study showed that our modified device could measure the self-propulsion distance, excluding assistance propulsion distance in wheelchair users.

BACKGROUND: Higher physical activity levels during hospitalization may benefit the life-space mobility, defined as the ability to move within environments that expand from one's home to the greater community, of stroke survivors following their discharge. OBJECTIVES: This study aimed to evaluate the relationship between physical activity levels during rehabilitation hospitalization and life-space mobility among stroke survivors three months after their discharge. METHODS: We recruited 84 stroke survivors as prospective participants from four convalescent rehabilitation hospitals. Physical activity levels during hospitalization were assessed using pedometers with a three-axis accelerometer, and their average step count over 14 consecutive days prior to discharge was used as the representative set of values. Pedometers were placed on the participant's waist or wrist on the non-paretic side. The Life-Space Assessment (LSA), a validated self-reporting measure for assessing community mobility, was implemented three months following participant discharge from rehabilitation hospitals via a mail-in survey method. To determine the relationship between the participants' level of physical activity during hospitalization and the LSA score following discharge, we performed multivariate regression analysis. RESULTS: A total of 75 participants (89.3%) completed the post-discharge survey and were therefore included in the analysis. The multiple regression analysis, controlled for age, balance function, walking endurance, fear of falling, and functional status, revealed that daily step counts were significantly associated with the LSA score three months after discharge (ß = 0.241, p = .026). CONCLUSIONS: Physical activity levels during hospitalization were significantly associated with the life-space mobility of stroke survivors following discharge.

OBJECTIVE: The aim of this study was to investigate the relationship between tongue muscle quality index, which was represented as tongue muscle pressure divided by tongue muscle mass, and swallowing speed in community-dwelling older women. METHODS: The inclusion criteria for this cross-sectional study were that participants be community-dwelling older women aged 65 years and above without dysphagia. The exclusion criteria were stroke and Parkinson's disease that directly cause dysphagia. We measured tongue muscle thickness and maximum tongue pressure and the tongue muscle quality index, which was defined as the maximum tongue pressure divided by tongue muscle thickness. We investigated swallowing speed via a 100 ml water swallowing test. To assess the relationship between tongue muscle characteristics and swallowing speed, we performed stepwise multiple regression analysis. RESULTS: Ninety-three participants were enrolled in this study (mean age: 84.2 ± 4.7 years). A stepwise multiple regression analysis showed that age (ß = - 0.292, p < 0.01) and tongue muscle quality index (ß = 0.267, p < 0.01) were related to swallowing speed. CONCLUSION: We found that tongue muscle quality index was related to swallowing speed in community-dwelling older women. According to our findings, it is possible that the tongue muscle quality index is a useful parameter for assessing swallowing speed in older women without dysphagia.

Factors associated with functional recovery after stroke may differ by age demographics because the aging process leads to various regressive changes. The aim of this study was to identify factors related to functional recovery in Japanese patients with convalescent stroke stratified by age. A multicenter retrospective observational study was conducted in 243 patients from six convalescent inpatient rehabilitation wards. Participants were categorized into three groups: 40-64, 65-74, and ≥75 years. Demographic data, laboratory data, physical function, and cognitive function were collected upon admission, and outcome measures were represented using the relative gain of the Functional Independence Measure (FIM effectiveness) during hospitalization. Stepwise multivariate logistic analysis was performed to identify the significant factors for functional recovery in each group. In the 40-64 years group, stroke type [odds ratio (OR), 10.38; 95% confidence interval (CI), 2.22-48.59], spatial neglect (OR, 7.61; 95% CI, 2.07-28.00), and memory disorder (OR, 4.68; 95% CI, 1.08-20.30) were shown to be significant factors. In the 65-74 years group, only memory disorder (OR, 3.42; 95% CI, 1.19-9.81) was significant. In the ≥75 years group, low albumin level (OR, 3.35; 95% CI, 1.05-10.67), severe motor impairment (OR, 5.11; 95% CI, 1.14-22.97), and memory disorder (OR, 4.34; 95% CI, 1.43-13.23) were significantly related to poor functional recovery. In conclusions, the findings showed that there were different trends among the factors related to poststroke functional recovery among the three age groups.

AIM: The objective of this trial was to investigate the synergistic effects of bodyweight resistance exercise and a protein supplement with vitamin D on skeletal muscle in sarcopenic or dynapenic older adults. METHODS: This was a four-arm randomized controlled trial. Sarcopenic or dynapenic older adults were recruited for this trial. After screening, a total of 112 older adults were randomly allocated among four groups; 28 older adults each were enrolled in the combined resistance exercise and nutritional supplementation group, the exercise alone group, the nutritional supplementation alone group, and the control group. Participants in the combined group and exercise alone groups took part in a bodyweight resistance exercise program for 12 weeks. Protein and vitamin D supplements were provided every day for 12 weeks for the participants in the combined group and nutritional supplementation alone groups. We assessed the echo intensity of participants' thigh muscle using ultrasonography, measured their appendicular muscle mass using a bioelectrical impedance data acquisition system, and tested their knee extension strength and physical function. RESULTS: Participants in the combined group had a significantly greater improvement in rectus femoris echo intensity and knee extension torque than those in the other groups (P < 0.05). Furthermore, the combined program increased appendicular muscle mass in sarcopenic older adults (P < 0.05), but not in older adults with low physical function with normal muscle mass. CONCLUSIONS: The present study confirmed the synergistic effect of bodyweight resistance exercise and protein supplement with vitamin D on muscle quality and muscle strength in sarcopenic or dynapenic older adults.

OBJECTIVE: To investigate the impact of unilateral spatial neglect with or without other cognitive impairments on recovery of independent gait in stroke survivors. DESIGN: A prospective cohort study. SUBJECTS: Ninety-four stroke survivors in an inpatient rehabilitation ward. METHODS: The presence of unilateral spatial neglect was assessed by the visuospatial perception score of the Stroke Impairment Assessment Set, and other cognitive impairments were assessed by Mini-Mental State Examination. Participants were categorized into 3 groups: group 1, unilateral spatial neglect with other cognitive impairments; group 2, unilateral spatial neglect without other cognitive impairments; and group 3, non-unilateral spatial neglect. The outcome was the walking score of the Functional Independence Measure (FIM) at discharge (score ≥ 6 or ≤ 5). RESULTS: Multivariate logistic regression analysis (reference, group 3) showed that the presence of unilateral spatial neglect with other cognitive impairments (group 1) had a significant association with dependence of gait (p = 0.003), and the odds ratio (95% confidence interval) was 5.55 (1.19-23.04). In contrast, there was no significant relationship between the presence of unilateral spatial neglect without other cognitive impairments (group 2) and dependence of gait (p = 0.207). CONCLUSION: The presence of unilateral spatial neglect without other cognitive impairments is not a significant factor for regaining independent gait. In contrast, unilateral spatial neglect becomes a strong negative factor when combined with other cognitive impairments.

PURPOSE: To examine the relationship between oral function and sarcopenia staging, including dynapenia and presarcopenia, in community-dwelling older adults. METHODS: A cross-sectional study was performed in community-dwelling older women aged 65 years and above. We measured oral muscle strength using maximum tongue pressure, oral muscle performance using oral diadochokinesis, and subjective swallowing difficulties using the Eating Assessment Tool. We measured skeletal muscle mass and function and other variables. All participants were divided into 4 groups (normal, presarcopenia, dynapenia, and sarcopenia) using an algorithm that operationally defines sarcopenia staging by skeletal muscle characteristics. A general linear model was used to analyze differences in oral function among the 4 groups. RESULTS: A total of 245 participants were enrolled (median age [IQR], 81.0 [75.0-85.0]). The proportion of normal participants and those with presarcopenia, dynapenia, and sarcopenia was 48.6% (n = 119), 9.4% (n = 23), 30.2% (n = 74), and 11.8% (n = 29), respectively. The sarcopenia and dynapenia groups had significantly lower maximum tongue pressure and oral diadochokinesis than the normal group. In the multivariate analysis, after adjusting for age, maximum tongue pressure and oral diadochokinesis were found to be significantly lower in the sarcopenia and dynapenia groups than in the normal group. CONCLUSIONS: In this study, participants with sarcopenia and dynapenia showed low oral function, and similar trends were indicated for oral function and skeletal muscle according to progression of sarcopenia staging. Future research should clarify the characteristics of swallowing-related muscles, including muscle mass, strength, and performance at each sarcopenia stage.

BACKGROUND: Sarcopenia is diagnosed on the basis of skeletal muscle mass and muscle strength/function. However, more simple and accurate measures for muscle mass and muscle strength/function should be explored. OBJECTIVE: The aim of this study was to compare the skeletal muscle characteristics at each stage of sarcopenia (normal, presarcopenia, dynapenia, and sarcopenia) via ultrasonography, multifrequency bioelectrical impedance analysis (BIA), and physical assessment batteries in community-dwelling older adults. By evaluating the relationship between muscle quality/quantity indicators and muscle mass/muscle function, we attempted to identify better muscle quantity and quality indicators for the diagnosis of sarcopenia. SETTING AND SUBJECTS: Community-dwelling older men (n = 100, 81.6 ± 7.4 years) and women (n = 247, 79.7 ± 6.9 years) participated in this study. MEASUREMENTS: Skeletal muscle quantity and quality were measured by ultrasonography and multifrequency BIA. Ultrasonographic (thickness and echo intensity) and multifrequency BIA (volume and density) indicators, as well as physical assessment measures, were compared among each stage of sarcopenia. In addition, receiver-operating characteristic analysis was used to assess the sensitivity and specificity of each indicator. RESULTS: Most of the muscle quantity indicators were lower in the sarcopenia and presarcopenia groups than in the other groups, whereas most of the muscle quality indicators were lower in the sarcopenia and dynapenia groups than in the other groups. According to the receiver-operating characteristic analysis, quadriceps muscle thickness and thigh muscle volume were better indicators of muscle mass, whereas the quadriceps muscle echo intensity and thigh muscle density were more robust indicators of muscle function. CONCLUSIONS: In this study, we found potential muscle quality and quantity indicators for sarcopenia diagnosis by ultrasonography and multifrequency BIA. Future longitudinal studies are warranted to define the role of these indicators for the diagnosis of sarcopenia.
