Prognostic Importance of B-Type Natriuretic Peptide Level in Patients Undergoing Catheter Ablation for Atrial Fibrillation.

BACKGROUND: This study assessed the prognostic importance of B-type natriuretic peptide (BNP) concentrations for clinical events after catheter ablation for atrial fibrillation (AF).Methods and Results: We enrolled 1,750 consecutive patients undergoing initial AF ablation whose baseline BNP data were available from a large-scale multicenter observational cohort (TRANQUILIZE-AF Registry). The prognostic impact of BNP concentration on clinical outcomes, including recurrent tachyarrhythmias and a composite of heart failure (HF) hospitalization or cardiac death, was evaluated. Median baseline BNP was 94.2 pg/mL. During a median follow-up of 2.4 years, low BNP (<38.3 pg/mL) was associated with lower rates of recurrent atrial tachyarrhythmias than BNP concentrations ≥38.3 pg/mL (19.9% vs. 30.6% at 3 years; P<0.001) and HF (0.8% vs. 5.3% at 3 years; P<0.001). Multivariable Cox regression analyses revealed that low BNP was independently associated with lower risks of arrhythmia recurrence (hazard ratio [HR] 0.63; 95% confidence interval [CI] 0.47-0.82; P<0.001) and HF (HR 0.17; 95% CI 0.04-0.71; P=0.002). The favorable impact of low BNP on arrhythmia recurrence was prominent in patients with paroxysmal, but not non-paroxysmal, AF, particularly among those with long-standing AF. CONCLUSIONS: Low BNP concentrations had a favorable impact on clinical outcomes after AF ablation. The heterogeneous impact of baseline BNP concentrations on arrhythmia recurrence for the subgroups of patients divided by AF type warrants future larger studies with longer follow-up periods.

The significance of information and communication technology education via tablets in college of physical therapy.

[Purpose] This study aimed to clarify whether collaborative learning could be promoted via information and communication technology education using tablets at college of physical therapy. [Participants and Methods] An online survey was conducted to evaluate collaborative learning among 81 first-year students at the Department of Physical Therapy actively using tablets in classes (six specific categories). [Results] The Friedman test had significant results, and a significant primary effect was observed between each questionnaire item. Following this, the Bonferroni test was performed for multiple comparisons, with significant differences were observed among certain items. [Conclusion] We reported employing tablets in the classroom positively impacted collaborative learning. Here, among the evaluations of collaborative learning, the items with the best results corresponded mainly to communication activation between students.

Association of Concomitant Coronary Artery Disease With Cardiovascular Events in Patients With Atrial Fibrillation　- The Fushimi AF Registry.

BACKGROUND: Atrial fibrillation (AF) patients often have concomitant coronary artery disease (CAD); however, there are little data on clinical characteristics and outcomes of such patients in daily clinical practice in Japan.Methods and Results: The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. Follow-up data were available for 4,464 patients, and the median follow up was 5.1 (interquartile range: 2.3-8.0) years. History of CAD was present in 647 patients (14%); of those patients, 267 (41%) had history of myocardial infarction (MI). Patients with CAD were older and had more comorbidities than those without CAD. The crude incidences (% per patient-year) of cardiovascular events were significantly higher in patients with CAD than those without CAD (cardiac death: 1.8 vs. 0.7, stroke or systemic embolism [SE]: 2.9 vs. 2.1, MI: 0.6 vs. 0.1, composite of those events: 5.1 vs. 2.8, respectively, all log-rank P<0.01). After multivariate adjustment, concomitant CAD was associated with incidence of cardiac events, and history of MI was associated with incidence of MI; however, neither history of CAD nor MI was associated with the incidence of stroke/SE. CONCLUSIONS: In Japanese AF patients, concomitant CAD was associated with higher prevalences of major co-morbidities and higher incidences of cardiovascular events; however, history of CAD was not associated with the incidence of stroke/SE.

10-Year Trends of Antithrombotic Therapy Status and Outcomes in Japanese Atrial Fibrillation Patients　- The Fushimi AF Registry.

BACKGROUND: Atrial fibrillation (AF) increases the risk of stroke and death. Oral anticoagulants (OAC) are highly effective in reducing the risk of stroke, and direct oral anticoagulants (DOAC) became available worldwide in 2011.Methods and Results:The Fushimi AF Registry is an on-going prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. The study cohort consisted of 4,489 patients (mean age 73.6 years, 59.6% male, mean CHADS2score 2.03), enrolled in 2011-2017. From 2011 to 2021, antithrombotic therapy has undergone a major transition; the proportion of patients receiving OAC has increased from 53% to 70%, with a steady uptake of DOAC (from 2% to 52%), whereas the proportion of patients receiving antiplatelet agents has decreased from 32% to 14%. Over a median follow-up of 5.1 years, the incidence of stroke/systemic embolism (SE), major bleeding, and all-cause death was 2.2%, 1.9%, and 4.9% per patient-year, respectively. The incidence of stroke/SE (1.6% vs. 2.3%; P<0.01), major bleeding (1.6% vs. 2.0%; P=0.07), and death (4.2% vs. 5.0%; P<0.01) was lower among patients enrolled in 2014-2017 than in 2011-2013, despite comparable baseline characteristics (age 73.2 vs. 73.7 years, CHADS2score 2.03 vs. 2.04, and HAS-BLED score 1.67 vs. 1.77, respectively). CONCLUSIONS: Over the past 10 years, there has been a major transition in antithrombotic therapy and a decline in the incidence of adverse events in AF patients.

Matched comparison of catheter ablation versus conservative management for atrial fibrillation.

It is still controversial whether catheter ablation for atrial fibrillation (AF) could improve clinical outcomes in general AF population. Among 4398 patients with diagnosis of AF in the outpatient department of Kyoto University Hospital between January 2005 and March 2015, we identified 537 pairs of patients who received first-time catheter ablation (ablation group) or conservative management (conservative group), matched for age, gender, AF duration, AF type, AF symptoms, and previous heart failure (HF). The primary outcome measure was a composite of cardiovascular death, HF hospitalization, ischemic stroke, or major bleeding. Most baseline characteristics were well balanced between the 2 groups, except for the higher prevalence of low body weight, history of malignancy, and severe chronic kidney disease in the conservative group. Median follow-up duration was 5.3 years. The cumulative 5-year incidence of the primary outcome measure was significantly lower in the ablation group than in the conservative group (5.2% versus 15.6%, log-rank P < 0.001). Even after adjusting for the imbalances in the baseline characteristics, the lower risk of the ablation group relative to the conservative group for the primary outcome measure remained highly significant (HR 0.32, 95% CI 0.21-0.47, P < 0.001). Ablation compared with conservative management was also associated with significantly lower risks for the individual components of the primary outcome. In this matched analysis in AF patients, ablation as compared with conservative management was associated with better long-term clinical outcomes, although we could not deny the possibility of selection bias and unmeasured confounding.

[Purpose] The purpose of this study is to consider the correlation between ankle plantar flexion strength and degree of body sway. [Participants and Methods] Twenty-one healthy adult males were targeted. A handheld dynamometer was used to measure ankle plantar flexion strength. The Body Pressure Measurement System was used to measure the degree of body sway. Lastly, correlation between ankle plantar flexion strength and degree of body sway was considered. [Results] A negative correlation was observed between ankle plantar flexion strength and degree of body sway. [Conclusion] Regarding ankle plantar flexion strength and degree of body sway, results of a consideration using a handheld dynamometer and Body Pressure Measurement System were the same as that of previous studies using large equipment.

Overview of the 84th Annual Scientific Meeting of the Japanese Circulation Society　- Change Practice!

Due to the COVID-19 pandemic, the 84thAnnual Meeting of the Japanese Circulation Society (JCS) was held in a web-based format for the first time in its history as "The Week for JCS 2020" from Monday, July 27 to Sunday, August 2, 2020. All sessions, including general abstracts, were streamed live or on-demand. The main theme of the meeting was "Change Practice!" and the aim was to organize the latest findings in the field of cardiovascular medicine and discuss how to change practice. The total number of registered attendees was over 16,800, far exceeding our expectations, and many of the sessions were viewed by far more people than at conventional face-to-face scientific meetings. At this conference, the power of online information dissemination was fully demonstrated, and the evolution of online academic meetings will be a direction that cannot be reversed in the future. The meeting was completed with great success, and we express our heartfelt gratitude to all affiliates for their enormous amount of work, cooperation, and support.

Predictors of activities of daily living at discharge in elderly patients with heart failure with preserved ejection fraction.

The purpose of this study was to clarify the predictive factors of activities of daily living (ADL) at discharge in elderly patients with heart failure with preserved ejection fraction (HFpEF). Participants were selected from among 598 consecutive hospitalized HF patients based on certain criteria. We investigated patient characteristics, and ADL with the motor and cognitive items of the Functional Independence Measure (FIM). We analyzed the data with the unpaired t test, Mann-Whitney U test, χ2 test, logistic regression analysis, and receiver operating characteristic (ROC) curves. We included 154 patients for further analyses who were divided into the low ADL group (n = 75) and high ADL group (n = 79). There were significant differences between the two groups in age, long-term care insurance (LTCI) level, New York Heart Association class, creatinine level, albumin level, ß-blocker, sitting, standing and walking exercise start days, length of hospital stay, and motor- and cognitive-FIM scores at admission and discharge (p < 0.05). The cutoff values of the ROC curves predicting ADL at discharge were LTCL: support level 2 (area under the curve [AUC]: 0.672, p < 0.001, sensitivity: 0.573, false-positive rate: 0.278); walking exercise start day: 4.5 days (AUC 0.694, p < 0.001, sensitivity: 0.609, false-positive rate: 0.299); motor FIM score: 34.5 points (AUC 0.710, p < 0.001, sensitivity: 0.633, false-positive rate: 0.280); and cognitive FIM score: 28.5 points (AUC 0.806, p < 0.001, sensitivity: 0.759, false-positive rate: 0.227). This study revealed several predictors of ADL at discharge and their associated cutoff values in elderly patients with HFpEF.

Correlation between leg extensor torque and the degree of sway.

[Purpose] The purpose of this study was to examine the correlation between leg extensor torque and the degree of sway. [Participants and Methods] We recruited 31 male and 22 female healthy adults. Strength Ergo 240 was used to measure leg extensor torque. A body pressure measurement system was used to measure the degree of sway. After the measurement, the correlation between these factors was investigated according to sex. [Results] In the males, a significant negative correlation was observed between leg extensor torque and the degree of sway. [Conclusion] In cases where therapists actively performed muscle strengthening and standing-up exercises to reduce the degree of sway in the males, the possibility that such efforts could increase leg extensor torque was observed.

Correlation between ankle plantar flexor strength and leg extensor torque.

[Purpose] The purpose of this study is to consider the correlation between ankle plantar flexor strength and leg extensor torque in order to investigate whether the leg extension torque can be expected to increase as the triceps surae muscle strength is increased. [Participants and Methods] Healthy adults of 30 males and 22 females were recruited. Hand Held Dynamometer was used to measure ankle plantar flexor strength. Strength Ergo 240 was used to measure leg extensor torque. After measurement, a correlation between these factors was investigated by gender. [Results] For both males and females, a significant positive correlation between the left and right ankle plantar flexor strength and leg extensor torque was observed. [Conclusion] Actively performing muscle strengthening exercises for ankle plantar flexor by physical therapists was found to be meaningful in increasing leg extensor torque.

Impact of Pre-Existing Bradycardia on Subsequent Need for Pacemaker Implantation After Radiofrequency Catheter Ablation for Atrial Fibrillation.

BACKGROUND: The incidence of subsequent need for permanent pacemaker implantation (PMI) after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) in real world patients with and without pre-existing bradycardia has not yet been fully evaluated. Methods and Results: A total of 1,131 consecutive patients undergoing first-time RFCA for AF who had no previous or planned device implantation, were enrolled in the present study. Of 799 paroxysmal AF (PAF) patients, 121 (15.1%) had sinus node dysfunction (SND). Of 332 non-PAF patients, 73 (22.0%) had slow ventricular response (VR), defined as heart rate <80 beats/min at rest without any rate-control drugs. The 5-year cumulative incidence of PMI after RFCA in PAF patients with and without SND was 14.8% and 1.7%, respectively (P<0.001). The 5-year cumulative incidence of PMI after RFCA in non-PAF patients with and without slow VR was 14.8% and 4.7%, respectively (P<0.001). SND and female gender in PAF patients, as well as slow VR and age ≥75 years in non-PAF patients, were independent and additive predictors of PMI. The 5-year cumulative incidence of PMI was 26.3% in female PAF patients with SND and 33.3% in elderly non-PAF patients with slow VR. CONCLUSIONS: PMI was avoided in >85% of patients undergoing RFCA for PAF with pre-existing SND, although care should be taken for female patients. Decision-making regarding RFCA for non-PAF patients with slow VR, especially in the elderly, should be cautious.

Efficacy of Antiarrhythmic Drugs Short-Term Use After Catheter Ablation for Atrial Fibrillation (EAST-AF) trial.

AIMS: Substantial portion of early arrhythmia recurrence after catheter ablation for atrial fibrillation (AF) is considered to be due to irritability in left atrium (LA) from the ablation procedure. We sought to evaluate whether 90-day use of antiarrhythmic drug (AAD) following AF ablation could reduce the incidence of early arrhythmia recurrence and thereby promote reverse remodelling of LA, leading to improved long-term clinical outcomes. METHODS AND RESULTS: A total of 2038 patients who had undergone radiofrequency catheter ablation for paroxysmal, persistent, or long-lasting AF were randomly assigned to either 90-day use of Vaughan Williams class I or III AAD (1016 patients) or control (1022 patients) group. The primary endpoint was recurrent atrial tachyarrhythmias lasting for >30 s or those requiring repeat ablation, hospital admission, or usage of class I or III AAD at 1 year, following the treatment period of 90 days post ablation. Patients assigned to AAD were associated with significantly higher event-free rate from recurrent atrial tachyarrhythmias when compared with the control group during the treatment period of 90 days [59.0 and 52.1%, respectively; adjusted hazard ratio (HR) 0.84; 95% confidence interval (CI) 0.73-0.96; P = 0.01]. However, there was no significant difference in the 1-year event-free rates from the primary endpoint between the groups (69.5 and 67.8%, respectively; adjusted HR 0.93; 95% CI 0.79-1.09; P = 0.38). CONCLUSION: Short-term use of AAD for 90 days following AF ablation reduced the incidence of recurrent atrial tachyarrhythmias during the treatment period, but it did not lead to improved clinical outcomes at the later phase.

Measuring hip flexor and extensor strengths across various postures using a fixed belt.

[Purpose] The purpose of this study was to evaluate hip flexor and extensor strength due to differences in posture measurement. [Subjects and Methods] Healthy adults (26 males and 24 females) were enrolled. Using a hand-held dynamometer, hip flexor and extensor strengths were measured in various postures and in a basic posture (sitting posture and hip/knee joint flexed 90°) according to the Manual Muscle Testing procedure. While calculating intraclass correlation coefficients by measurement, hip flexor and extensor strengths were compared in males and females for every posture. [Results] Intraclass correlation coefficients were greater than 0.7 in every measurement. There was no significant difference in hip flexor and extensor strengths in both males and females. Furthermore, there was a significant difference in right and left hip flexor strengths and in left hip extensor strength. [Conclusion] Hip flexor and extensor strengths can be simply and easily measured using a hand-held dynamometer.

Adenosine triphosphate-guided pulmonary vein isolation for atrial fibrillation: the UNmasking Dormant Electrical Reconduction by Adenosine TriPhosphate (UNDER-ATP) trial.

AIMS: Most of recurrent atrial tachyarrhythmias after pulmonary vein isolation (PVI) for atrial fibrillation (AF) are due to reconnection of PVs. The aim of the present study was to evaluate whether elimination of adenosine triphosphate (ATP)-induced dormant PV conduction by additional energy applications during the first ablation procedure could reduce the incidence of recurrent atrial tachyarrhythmias. METHODS AND RESULTS: We randomly assigned 2113 patients with paroxysmal, persistent, or long-lasting AF to either ATP-guided PVI (1112 patients) or conventional PVI (1001 patients). The primary endpoint was recurrent atrial tachyarrhythmias lasting for >30 s or those requiring repeat ablation, hospital admission, or usage of Vaughan Williams class I or III antiarrhythmic drugs at 1 year with the blanking period of 90 days post ablation. Among patients assigned to ATP-guided PVI, 0.4 mg/kg body weight of ATP provoked dormant PV conduction in 307 patients (27.6%). Additional radiofrequency energy applications successfully eliminated dormant conduction in 302 patients (98.4%). At 1 year, 68.7% of patients in the ATP-guided PVI group and 67.1% of patients in the conventional PVI group were free from the primary endpoint, with no significant difference (adjusted hazard ratio [HR] 0.89; 95% confidence interval [CI] 0.74-1.09; P = 0.25). The results were consistent across all the prespecified subgroups. Also, there was no significant difference in the 1-year event-free rates from repeat ablation for any atrial tachyarrhythmia between the groups (adjusted HR 0.83; 95% CI 0.65-1.08; P = 0.16). CONCLUSION: In the catheter ablation for AF, we found no significant reduction in the 1-year incidence of recurrent atrial tachyarrhythmias by ATP-guided PVI compared with conventional PVI.

Effects of self-monitoring using an accelerometer on physical activity of older people with long-term care insurance in Japan: a randomized controlled trial.

PURPOSE: This study aimed to investigate the effects of a self-monitoring intervention to promote an increase in physical activity, as measured by step count, and reduce sedentary behavior in older people covered by the long-term care insurance system (LTCI) in Japan. METHODS: This was a randomized controlled trial conducted at a daycare center from October 2022 to January 2023. Fifty-two older adults with LTCI who were able to walk with or without aids were assigned to an intervention (n = 26) group and control (n = 26) group. During the 5-week follow-up period, the intervention group received education on physical activity and self-monitoring such as goal setting, self-management and feedback. The primary outcome was step count, and the secondary outcome was sedentary behavior. RESULTS: Participants who completed the study to the end of the 5-week follow-up and drop-out participants for whom outcome data were available were included in the final analysis of 57 participants, n = 24 (79.8 ± 8.8 years, male 25.5%) in the intervention group and n = 23 (82.5 ± 8.5 years, male 39.1%) in the control group. Comparisons between the two groups at baseline showed no significant differences. In the results of a two-way mixed analysis of variance (ANOVA) including 2 (group: control, intervention) × 2 (term: baseline, 5-week follow-up) factors, an interaction was observed in the number of steps, sedentary behavior, and light physical activity (p < 0.05). CONCLUSION: Self-monitoring of physical activity using an accelerometer may be effective in increasing the number of steps and light physical activity and in reducing sedentary behavior in older people with LTCI.

Atrial fibrillation type and long-term clinical outcomes in hospitalized patients with heart failure: insight from JROADHF.

AIMS: Atrial fibrillation (AF) type (paroxysmal, persistent, or permanent) is important in determining therapeutic management; however, clinical outcomes by AF type are largely unknown for hospitalized patients with heart failure (HF). METHODS AND RESULTS: The Japanese Registry Of Acute Decompensated Heart Failure is a retrospective, multicenter, and nationwide registry of patients hospitalized for acute HF in Japan. Follow-up data were collected up to 5 years after hospitalization. Patients were divided based on diagnosis and AF type into 3 groups [without AF, paroxysmal AF, and sustained AF (defined as a composite of persistent and permanent AF)], and compared the backgrounds and outcomes between the groups. Of 12 895 hospitalized HF patients [mean age: 78 ± 13 years, female: 6077 (47%), and mean left ventricular ejection fraction: 47 ± 17%], 1725 had paroxysmal AF, and 3672 had sustained AF. Compared with patients without AF, sustained AF had a higher risk of the primary composite endpoint of cardiovascular (CV) death or HF hospitalization [hazard ratio (HR): 1.09, 95% confidence interval (CI): 1.01-1.17; P = 0.03], mainly driven by HF hospitalization [HR: 1.16, 95% CI: 1.06-1.26; P < 0.001], whereas the corresponding risk for the primary endpoint in patients with paroxysmal AF was not elevated (HR: 1.03, 95% CI: 0.94-1.13; P = 0.53) after adjustment by multivariable Cox regression analysis. These results were consistent among the subgroups of patients with reduced or preserved ejection fraction (interaction P = 0.74). CONCLUSION: Among hospitalized patients with HF, sustained AF, but not paroxysmal AF, was significantly associated with a higher risk for CV death or HF hospitalization, indicating the importance of accounting for AF type in HF patients.

Association of Regression from Sustained to Paroxysmal Atrial Fibrillation With Clinical Outcomes: The Fushimi AF Registry.

In some cases, albeit infrequently, patients with atrial fibrillation (AF) may experience a regression from a sustained to a paroxysmal type. We sought to investigate how regression of AF is associated with outcomes. Among the patients with AF enrolled in the Fushimi AF Registry who were identified as having sustained AF at baseline, conversion of sustained to paroxysmal AF during follow-up was defined as AF regression. Major adverse cardiovascular events (MACEs) were defined as a composite of cardiac death, myocardial infarction, ischemic stroke, systemic embolism, or hospitalization due to heart failure. Among 2,261 patients with sustained AF at baseline, AF regression was observed in 214 (9.5%) patients over a median follow-up period of 5.8 years (1.78% per patient-year). The annual incidence of MACE was significantly lower in patients with AF regression than in those without (3.47% vs 6.59% per patient-year, p <0.001, adjusted hazard ratio [HR] 0.53, 95% confidence interval [CI] 0.38 to 0.72). Furthermore, AF regression was significantly associated with reduced risk of MACE during and after the regression period from sustained to paroxysmal forms (during the regression period: adjusted HR 0.45, 95% CI 0.22 to 0.90; after the regression period: adjusted HR 0.43, 95% CI 0.26 to 0.67). The incidence of MACE was comparable between spontaneous regression (35/178: 19.7%) and therapy-associated regression (either receiving catheter ablation or antiarrhythmic drugs before the regression) (7/36: 19.4%) (p = 0.98). Regression of AF was associated with lower incidence of adverse cardiovascular events. The risk of adverse events decreased significantly during the regression period, and this reduced risk persisted after regression.

Association of left atrial enlargement with heart failure events in non-valvular atrial fibrillation patients with preserved left ventricular ejection fraction.

Aims: Atrial fibrillation (AF) increases the risk of heart failure (HF); however, little is known regarding the risk stratification for incident HF in AF patients, especially with preserved left ventricular ejection fraction (LVEF). Methods and results: The Fushimi AF Registry is a community-based prospective survey of AF patients. From the registry, 3002 non-valvular AF patients with preserved LVEF and with the data of antero-posterior left atrial diameter (LAD) at enrolment were investigated. Patients were stratified by LAD (<40, 40-44, 45-49, and ≥50 mm) with backgrounds and HF hospitalization incidences compared between groups. Of 3002 patients [mean age, 73.5 ± 10.7 years; women, 1226 (41%); paroxysmal AF, 1579 (53%); and mean CHA2DS2-VASc score, 3.3 ± 1.7], the mean LAD was 43 ± 8 mm. Patients with larger LAD were older and less often paroxysmal AF, with a higher CHA2DS2-VASc score (all P < 0.001). Heart failure hospitalization occurred in 412 patients during the median follow-up period of 6.0 years. Larger LAD was independently associated with a higher HF hospitalization risk [LAD ≥ 50 mm: hazard ratio (HR), 2.36; 95% confidence interval (CI), 1.75-3.18; LAD 45-49 mm: HR, 1.84; 95% CI, 1.37-2.46; and LAD 40-44 mm: HR, 1.34; 95% CI, 1.01-1.78, compared with LAD < 40 mm) after adjustment by age, sex, AF type, and CHA2DS2-VASc score. These results were also consistent across major subgroups, showing no significant interaction. Conclusion: Left atrial diameter is significantly associated with the risk of incident HF in AF patients with preserved LVEF, suggesting the utility of LAD regarding HF risk stratification for these patients.

Differences in Improvement of Physical Function in Older Adults with Long-Term Care Insurance with and without Falls: A Retrospective Cohort Study.

(1) Background: This study examined the differences in changes in physical function with and without falls after daycare use among frail older adults with long-term care insurance (LTCI). (2) Methods: In this retrospective cohort study, 82 of 96 consecutive daycare center users met the inclusion criteria. The participants were divided into two groups based on the presence or absence of falls 6-12 months after use. Participant characteristics in the fall and non-fall groups and physical function at baseline and six months in each group were compared. Using analysis of covariance, we analyzed physical function and its changes between the two groups, and cut-off values were calculated using receiver operating characteristic curves. (3) Results: Gait speed, timed up-and-go test, and 30 s chair stand test (CS30) improved significantly over six months in the no-fall group (n = 70) and all participants (n = 82) (p < 0.01). Gait speed in the fall group (n = 12) improved significantly over six months (p = 0.04). The fall group had significantly lower adjusted ΔCS30 scores than the no-fall group (p = 0.03), with a cutoff value of 2 (p = 0.024). (4) Conclusions: In older adults with LTCI, physical function with and without falls after daycare use differed by ΔCS30, with a cutoff value of 2.
