RESUMO
We aimed to verify the characteristics of lifestyles and frailty among older adults during and after the COVID-19 pandemic. This two-point cross-sectional study conducted a baseline survey (BL) in 2020 and a follow-up survey (FU) in 2023 with community-dwelling individuals aged ≥65 years in Japan. The 700 and 572 participants in the BL and FU were analyzed. We compared frailty occurrence and lifestyle characteristics between both surveys. In the BL and FU, 38.3 %, 52.4 %, and 9.3 % and 29.4 %, 59.4 %, and 11.2 % of the individuals were classified as robust, pre-frail, and frail, respectively, showing a significant decrease in the number of robust, and an increase in the number of pre-frail. A significant decrease in dietary intake was observed among robust individuals in the FU, with an overall significant decrease in communication opportunities in the BL. Therefore, lifestyle changes due to infection control measures may have a delayed impact on frailty.

BACKGROUND: The aim of this study was to determine the number of new subjective cognitive decline (SCD) complaints and associated factors in community-dwelling older adults during the COVID-19 pandemic in Japan. METHOD: A prospective cohort study was conducted in two periods: May to June 2020, and November 2020 to January 2021. We mailed a questionnaire to 1953 older adults in the first survey, and received 700 responses in the second. We analysed 534 participants without SCD in the first survey. We collected data on sociodemographic characteristics and administered the Questionnaire for Medical Checkup of Old-Old (QMCOO) to assess respondents' health condition. SCD was operationally defined using the QMCOO as reports of (1) forgetfulness, and (2) difficulty in naming dates. The subjects were divided into two groups by their condition at the second survey: an SCD (new SCD complaints) and a no-SCD (no new SCD complaints) group. RESULTS: A total of 85 (15.9%) participants had new SCD complaints. The Mann-Whitney U-test and chi-squared test showed that the SCD group had significantly more risk factors of SCD: walking speed (P = 0.001), smoking (P = 0.001), and existence of person with whom the patient could consult when disordered (P = 0.002). Multiple logistic regression analysis revealed that walking speed (odds ratio (OR) = 2.115, 95% confidence interval (CI): 1.259-3.553) and the presence of person to consult (OR = 3.619, 95% CI: 1.553-8.433) were significant related factors of new SCD complaints. CONCLUSION: Maintenance of physical condition and social support were associated with new SCD complaints during the COVID-19 pandemic.

AIM: The purpose of this study was to categorize and clarify transitions in the health status of older adults living in the community during the coronavirus disease (coronavirus disease 2019: COVID-19) pandemic. METHODS: The participants were older adults (≥65 years of age) who lived in Takasaki City, Gunma Prefecture. The survey items included basic information and subjective health perception (questionnaire for medical checkup of old-old). Latent class analyses were conducted for the first (baseline) and second surveys (6 months). The scores for each item were compared to identify the characteristics of each class at baseline and at 6 months. In addition, transitions in class affiliation from baseline to 6 months were summarized. RESULTS: A total of 434 of 1,953 participants (mean age: 79.1 years, 98 males and 336 females) completed the survey (22.2%). In both time periods, the responses were categorized into four classes: 1) good, 2) poor physical, oral and cognitive function, 3) poor social status and lifestyle, and 4) poor in all except social status and lifestyle. During 6 months of follow-up, a transition from the generally good class to the poor physical, oral and cognitive functions class was observed in many cases. CONCLUSIONS: The health status of the older adults living in the community was classified into four classes, and changes in health status occurred even within a short period of time during the COVID-19 pandemic.

[Purpose] We aimed to explore the factors that predict falls in community-dwelling older people over 6 months during their voluntary self-isolation for the coronavirus disease (SARS-CoV-2). [Participants and Methods] In this longitudinal study, we surveyed older people aged ≥65â years living in Takasaki City, Gunma Prefecture, using a questionnaire. We investigated the relationship between the frailty screening index and fall rate. [Results] A total of 588 older adults (response rate, 35.7%) filled and returned the questionnaire during the study period. Of these, 391 participants who had not applied for long-term care insurance and had completed the data on the response items were included in the study. Based on their responses in the survey questionnaire, 35 (8.95%) participants were grouped into the fall group and 356 into the non-fall group. Subsequently, the "no" response to "Can you recall what happened 5 minutes ago?" and "yes" response to "Have you felt tired for no reason (in the past 2 weeks)?" were identified as the significant factors associated with falls. [Conclusion] It is important to pay attention to the subjective evaluation of patients' cognitive decline and fatigue to prevent falls owing to the implementation of SARS-CoV-2 countermeasures.
RESUMO
BACKGROUND: Polymorphous adenocarcinoma is a common intraoral minor salivary gland carcinoma in Western countries but is extremely rare in Japan. The current study aimed to characterize the clinicopathological features and status of molecular alterations of polymorphous adenocarcinoma-associated genes, such as PRKD1/2/3, ARID1A, and DDX3X, in a large cohort of Japanese patients with polymorphous adenocarcinoma. METHODS: We examined the cases of 36 Japanese patients with salivary gland polymorphous adenocarcinoma and 26 cases involving histopathological mimics. To detect gene splits, fluorescence in situ hybridization was carried out for polymorphous adenocarcinoma-associated genes. Additionally, we applied a SNaPshot multiplex assay to identify PRKD1 hotspot mutations. RESULTS: This study revealed the indolent clinical course of polymorphous adenocarcinoma with a high 10-year overall survival rate (92.9%), accompanied by occasional local recurrences and cervical lymph node metastasis (23.3%). Twenty cases (55.6%) of polymorphous adenocarcinoma (but none of the mimics) exhibited alterations in at least one polymorphous adenocarcinoma-associated gene. Rearrangement of polymorphous adenocarcinoma-associated genes and PRKD1 E710D were identified in 17 (47.2%) and 4 (11.1%) cases, respectively; one case showed coexisting PRKD3 split and PRKD1 E710D. In the multivariate analysis, high clinical stage (p = 0.0005), the presence of prominent nucleoli (p = 0.0003), and ARID1A split positivity (p = 0.004) were independent risk factors for disease-free survival. CONCLUSION: Japanese patients with polymorphous adenocarcinoma showed clinicopathological features similar to those reported in Western countries. This study disclosed that polymorphous adenocarcinoma-associated genetic alterations were common and specific findings in polymorphous adenocarcinomas. The diagnostic role and possible prognostic significance of polymorphous adenocarcinoma-associated genetic alterations in polymorphous adenocarcinomas were suggested.

We aimed to verify the frailty status and the factors associated with the change in frailty status during the COVID-19 pandemic. A three-wave cohort study was conducted every six months, from May to July 2020, November 2020 to January 2021, and again from May to July 2021. The frailty status was assessed using the frailty screening index. Multivariate generalized linear mixed-effects models were used to determine whether changes in frailty status were associated with health conditions and lifestyle. The 404 survey forms were analyzed. Decline in chewing function (beta = 0.552) and leg muscle strength weakness (beta = 0.515) were significantly associated with the change in frailty status over six months, and leg muscle strength weakness (beta = 0.512) was significantly associated over 12 months. Risk factors associated with worsening health should be assessed for appropriate support. It is especially important to assess subjective leg muscle weakness in older adults.

AIM: This study aimed to investigate a method for scoring the questionnaire for medical checkup of old-old (QMCOO) and to clarify a cut-off score for the discrimination of frailty. METHODS: Survey forms were distributed to 2,586 older adults. For old-old adults, the item characteristics of the QMCOO were indicated using the item response theory (IRT). A receiver operating characteristic (ROC) analysis was performed using the total score of the fitting model of QMCOO for suggesting a cut-off score to discriminate frailty. The cross-validity of the cut-off score was verified among young-old adults. RESULTS: Among 1,680 adults who responded, data from 975 old-old and 421 young-old adults were analyzed. The method for scoring zero or one on each item in QMCOO conformed to the IRT model. The item discrimination and difficulty met the criteria. An ROC analysis showed that the area under the curve (AUC) and cut-off score for the discrimination of frailty were 0.871 and 4 points (sensitivity = 0.811, specificity = 0.766, positive likelihood ratio [LR+] = 3.469, and negative likelihood ratio [LR-] = 0.247), respectively. For young-old adults, the AUC and cut-off score were 0.874 and 4 points (sensitivity = 0.741, specificity = 0.817, LR+= 4.053, and LR- = 0.317), respectively. CONCLUSIONS: The method for scoring zero or one on each item of the QMCOO was valid. A cut-off score of 4 for the discrimination of frailty demonstrated the interpretability of the QMCOO, while the usefulness of the QMCOO in young-old adults demonstrated cross-validity.

AIM: This study aimed to clarify the construct validity of the Questionnaire for medical checkup of old-old (QMCOO). METHODS: In this cross-sectional study, questionnaires including the QMCOO were distributed to 1,953 older adults, and responses were returned by mail. We conducted an exploratory factor analysis (EFA) for the QMCOO among older participants (age ≥75 years) and extracted the relevant factors. Next, we structured the model for the QMCOO based on these factors and conducted a confirmatory factor analysis (CFA) using structural equation modeling. We conducted a CFA among young-older participants (age 65 to <75 years) for the same model. RESULTS: Of the 1,110 (53.5%) adults who responded, data from the 994 respondents who provided complete answers were analyzed. Five factors were extracted from the results of the EFA: physical and mental condition, relationship with society, eating and smoking, chance for exercise, and cognitive function. The results of the CFA were as follows: comparative fit index (CFI) = 0.899, adjusted goodness of fit index (AGFI) = 0.965, root mean square error of approximation (RMSEA) = 0.034, and standardized root mean square residual (SRMR) = 0.040. Meanwhile, the results for young-older participants were as follows: CFI = 0.886, AGFI = 0.942, RMSEA = 0.035, and SRMR = 0.048. CONCLUSIONS: The QMCOO assessed health condition and was composed of multiple factors associated with frailty. The CFA results indicated that the model fit was good. The QMCOO showed sufficient structural validity. Therefore, the construct validity of the QMCOO was shown.

[Purpose] This study aimed to assess fall-related risk factors among community-dwelling older adults during a period of voluntary self-isolation for preventing the spread of COVID-19. [Participants and Methods] This was a cross-sectional study. Survey questionnaire forms were distributed to 2,586 community-dwelling older adults in Takasaki City, Gunma Prefecture, Japan. Completed questionnaires were returned by mail. [Results] Of the 1,645 people who responded, 1,040 people aged 65 and over who did not apply for long-term care insurance and fully completed the questionnaire were included in this study. Since no in-person measurements were required, we utilized the Frailty Screening Index for the evaluations. We evaluated the relationship between questionnaire responses and fall rates among community-dwelling older adults. Among the results, "yes" responses to "Do you think you walk more slowly than before?" were identified as significantly associated with falls. [Conclusion] One must pay careful attention to subjectively assessing decreases in walking speed as a fall prevention measure during periods of self-restraint to prevent the spread of COVID-19 infection.
RESUMO
[Purpose] We aimed to obtain new findings by investigating the relationship between the presence or absence of falls and the results from the Frailty Screening Index (FSI), which can be easily carried out. [Participants and Methods] A total of 780 community-dwelling older adults (age ≥65â years) were classified based on whether they had fallen in the past year as those who had fallen at least once (fall group), and those who had not (non-fall group). We compared the study groups using sub-items of the FSI to extract more specific fall-related factors. The FSI is a questionnaire that comprises five items with simple 'yes/no' responses. [Results] The following three out of five sub-items of the FSI were extracted as fall-related factors: 1) "no" to the question, "Do you do physical exercise, like walking, at least once a week?"; 2) "yes" to the question, "Do you think you walk slower than before?"; and 3) "yes" to the question, "Have you felt tired for no reason (in the past two weeks)?" [Conclusion] The study results suggest the significance of paying attention to participant responses to the sub-items on the FSI, instead of merely determining their frailty risk based on their total score.
RESUMO
AIMS: Thymic carcinoma is rare and usually has a fatal outcome. Gene mutations in the epidermal growth factor receptor (EGFR) signalling pathway and TP53 have not been well analysed in thymic carcinoma. METHODS AND RESULTS: We examined a large cohort of thymic carcinoma and thymoma type A/B3 and looked for gene mutations in the RAS family, EGFR, PIK3CA, AKT1, BRAF and TP53. Among 54 thymic carcinoma cases, RAS family mutations were detected in 10 cases, EGFR in two, PIK3CA in one, AKT1 in one, BRAF in none and TP53 in five. Among 33 thymoma type A/B3 cases, HRAS gene mutation were found in one, PIK3CA in two and AKT1 in one. All these mutations were those of missense type activating mutations. RAS family mutations were significantly more frequent in thymic carcinoma than in thymoma type A/B3 (P = 0.0461). A prognostic analysis focusing on thymic squamous cell carcinoma cases (n = 44) showed that the overall survival was significantly shorter in patients with EGFR pathway mutations (n = 9) than in those without in a univariate analysis (P = 0.0173). Subsequently, EGFR pathway mutations were selected as an independent factor for a poor overall survival in a multivariate analysis (P = 0.0389). CONCLUSIONS: Mutations in the EGFR pathway and TP53 in thymic carcinoma may be frequent, and the EGFR pathway mutations may be associated with a poor prognosis in thymic squamous cell carcinoma patients. The therapeutic significance of gene mutations in thymic carcinoma should be further clarified.

AIMS: Adenoid cystic carcinoma (AdCC) is one of the most common salivary gland malignancies and the long-term prognosis is poor. In this study, we examined alterations of AdCC-associated genes, MYB, MYBL1, MYBL2 and NFIB, and their target molecules, including MYC. The results were correlated to clinicopathological profile of the patients. METHODS AND RESULTS: Using paraffin tumour sections from 33 cases of salivary gland AdCC, we performed a detailed fluorescence in-situ hybridization (FISH) analysis for gene splits and fusions of MYB, MYBL1, MYBL2 and NFIB. We found that 29 of 33 (88%) AdCC cases showed gene splits in either MYB, MYBL1 or NFIB. None of the cases showed an MYBL2 gene alteration. AdCCs were divided genetically into six gene groups, MYB-NFIB (n = 16), MYB-X (n = 4), MYBL1-NFIB (n = 2), MYBL1-X (n = 1), NFIB-X (n = 6) and gene-split-negative (n = 4). AdCC patients showing the MYB or MYBL1 gene splits were associated with microscopically positive surgical margins (P = 0.0148) and overexpression of MYC (P = 0.0164). MYC expression was detected in both ductal and myoepithelial tumour cells, and MYC overexpression was associated with shorter disease-free survival of the patients (P = 0.0268). CONCLUSIONS: The present study suggests that (1) nearly 90% of AdCCs may have gene alterations of either MYB, MYBL1 or NFIB, suggesting the diagnostic utility of the FISH assay, (2) MYB or MYBL1 gene splits may be associated with local aggressiveness of the tumours and overexpression of MYC, which is one of the oncogenic MYB/MYBL1 targets and (3) MYC overexpression may be a risk factor for disease-free survival in AdCC.

AIMS: Cancer/testis antigens (CTAs) are detected in cancer cells but not in healthy normal tissues, with the exception of gametogenic tissues. CTAs are highly immunogenic proteins, and thus represent ideal targets for cytotoxic T-lymphocyte-mediated specific immune therapy. The aim of this study was to screen CTA expression in various types of salivary gland carcinoma and to clarify clinicopathological significance of MAGE-A and NY-ESO-1 expression in adenoid cystic carcinomas (AdCCs) of the salivary gland, which is one of the most common salivary gland carcinomas, and usually has a fatal outcome. METHODS AND RESULTS: We used immunohistochemistry to examine the expression of four CTAs (MAGE-A, NY-ESO-1, CT7, and GAGE7) in various types of salivary gland carcinoma (n = 95). When carcinoma cases were divided into low-grade and intermediate/high-grade types, NY-ESO-1 and CT7 were expressed more frequently in intermediate/high-grade carcinomas. We then focused on MAGE-A and NY-ESO-1 expression in a large cohort of adenoid cystic carcinomas (AdCCs) (n = 46). MAGE-A and NY-ESO-1 were frequently expressed in AdCC; specifically, MAGE-A was expressed in >60% of the AdCC cases. MAGE-A expression and tumour site (minor salivary gland) were identified as independent risk factors for locoregional tumour recurrence. CONCLUSIONS: These findings suggest that CTAs may be expressed in a variety of salivary gland carcinomas, especially in those with higher histological grades. In addition, MAGE-A, which is frequently expressed in AdCC cases, may be a useful prognostic factor for poorer locoregional recurrence-free survival.

Striated duct adenoma of the salivary gland is a rare benign tumor characterized by unilayered duct epithelium and striations of the tumor cell membranes. To the best of our knowledge, only six cases have been reported in the literature. Here we report an additional case, which was complicated by an intra-tumoral hematoma on clinical presentation and by papillary thyroid carcinoma-like histology on intra-operative frozen section diagnosis. An asymptomatic 78-year-old male presented with a two-year-history of a painless tumor of the left parotid. An intra-tumoral hematoma, which is unusual for a salivary gland tumor, was suspected from results of pre-operative radiology. The patient then underwent a left parotidectomy. The intra-operative frozen section diagnosis indicated a benign tumor, although ectopic papillary thyroid carcinoma was raised as a differential diagnosis since the eosinophilic tumor cells occasionally possessed nuclear grooves and nuclear pseudo-inclusions. By precise histopathological examination using paraffin sections, the tumor was finally diagnosed as striated duct adenoma. This type of tumor has unique features of hypervascular stroma and papillary thyroid carcinoma-like nuclei. In our case, the former feature was associated with the intra-tumoral hematoma and the latter feature, with difficulty in frozen section tumor diagnosis.

The BIOMED-2 PCR protocol for targeting the IGH gene is widely employed for detecting clonality in B-cell malignancies. Unfortunately, the detection of clonality with this method is not very sensitive when paraffin sections are used as a DNA source. To increase the sensitivity, we devised a semi-nested modification of a JH consensus primer. The clonality detection rates of three assays were compared: the standard BIOMED-2, BIOMED-2 assay followed by BIOMED-2 re-amplification, and BIOMED-2 assay followed by semi-nested BIOMED-2. We tested more than 100 cases using paraffin-embedded tissues of various B-cell lymphomas, and found that the clonality detection rates with the above three assays were 63.9%, 79.6%, and 88.0%, respectively. While BIOMED-2 re-amplification was significantly more sensitive than the standard BIOMED-2, the semi-nested BIOMED-2 was significantly more sensitive than both the standard BIOMED-2 and BIOMED-2 re-amplification. An increase in sensitivity was observed in all lymphoma subtypes examined. In conclusion, tumor clonality may be detected in nearly 90% of B-cell lymphoma cases with semi-nested BIOMED-2. This ancillary assay may be useful when the standard BIOMED-2 fails to detect clonality in histopathologically suspected B-cell lymphomas.

The frequency of falls increases with age. In Japan, the population is aging rapidly, and fall prevention measures are an urgent issue. However, assessing fall risk during the coronavirus disease pandemic was complicated by the social distancing measures implemented to prevent the disease, while traditional assessments that involve actual measurements are complicated. This prospective cohort study predicted the risk of falls in community-dwelling older adults using an assessment method that does not require actual measurements. A survey was conducted among 434 community-dwelling older adults to obtain data regarding baseline attributes (age, sex, living with family, use of long-term care insurance, and multimorbidity), Frailty Screening Index (FSI) score, and Questionnaire for Medical Checkup of Old-Old (QMCOO) score. The participants were categorized into fall (n = 78) and non-fall (n = 356) groups. The binomial logistic regression analysis showed that it is better to focus on the QMCOO sub-item score, which focuses on multiple factors. The items significantly associated with falls were Q5 (odds ratio [OR] 1.95), Q8 (OR 2.33), and Q10 (OR 3.68). Our results were similar to common risk factors for falls in normal times. During the pandemic, being able to gauge the risk factors for falls without actually measuring them was important.

PURPOSE: To examine the association between consistent subjective cognitive decline and fall occurrence six months later. METHOD: A cohort study was conducted at two time points in community-dwelling older adults. The first survey was conducted from May to July 2020 and the second from November 2020 to January 2021. Older adults without missing data who had not fallen during the past year were analyzed. The questionnaire included sociodemographic data, a questionnaire for medical checkup of older adults, and a frailty screening index. We divided the participants into three groups according to the occurrence of subjective cognitive decline (SCD): 1) no SCD (did not complain of SCD at both time points), 2) unstable SCD (complained of SCD once), and 3) consecutive SCD (consistently complained of SCD). Multiple logistic regression analysis was used to examine the association between fall occurrence and SCD. Fall occurrences were obtained from the second survey. RESULTS: In total, 322 participants were included in the analysis. The numbers of patients with no SCD, unstable SCD, and consecutive SCD were 226 (70.2%), 61 (19.0%), and 35 (10.9%), respectively. In the second survey, the number of falls was 26 (8.1%). Multiple logistic regression analysis showed that consecutive SCD was associated with fall occurrence, even after adjusting for age, sex, comorbidity, cohabitants, and frailty status (OR:3.143, 95% CI:1.076-9.388); however, unstable SCD was not (OR:2.348, 95% CI:0.816-6.468). CONCLUSION: Consistent complaints of SCD were associated with the occurrence of falls. We highlighted the importance of evaluating SCD over time when considering falls.

BACKGROUND AND PURPOSE: Walking speed can be used to identify characteristics of frailty in older adults. It has a strong positive correlation with balance abilities. The Brief-Balance Evaluation Systems Test (Brief-BESTest) was developed to assess functions of the 6 balance control systems in a short time. However, for community-dwelling older adults, the relationship between walking speed and the Brief-BESTest needs to be clarified. Even the cutoff scores for each Brief-BESTest section should be indicated for physical therapists to effectively evaluate balance deficits. Our objective was to establish cutoff scores for individual Brief-BESTest sections, determine fast or slow walkers in community-dwelling older adults, and investigate the relationship between balance control systems and walking speed. METHODS: In a cross-sectional study involving 55 participants 77 years and older, the Brief-BESTest was evaluated after grouping the participants based on their walking speeds in public community centers. We compared the age, history of falls, handgrip strength, quadriceps strength, appendicular skeletal muscle mass index, comfortable walking speeds, and the Brief-BESTest scores between the fast- and slow-walking groups by using the independent t test, Fisher exact test, or Mann-Whitney U test. We also determined the receiver operating characteristic curves, and calculated the cutoff, area under the curve (AUC), sensitivity, and specificity of each section. RESULTS: All sections of the Brief-BESTest, except Section 1 (Biomechanical Constraints) were able to differentiate between fast and slow walkers in community-dwelling older women. Section VI (Stability in Gait) showed the highest AUC (0.83) and the cutoff score for the fast- and slow-walker groups was 3.0 points (sensitivity = 0.85, specificity = 0.81). Sections III, IV, and V (Anticipatory, Reactive, and Sensory Orientation, respectively) had moderate AUC (0.71-0.72). Sections I and II (Stability Limits) showed weak correlations with the walking speed. CONCLUSIONS: Three sections (III, anticipatory postural adjustments; IV, reactive postural responses; and VI, stability in gait) could differentiate between fast and slow walkers. Section VI was a particularly important balance function measurement that differentiated the walking speed with the highest accuracy. Therefore, it should be a primary focus when physical therapists treat community-dwelling older adults.

BACKGROUND: A method for assessing balance that differentiates between balance deficit can help guide effective interventions for preventing falls in older adults. OBJECTIVE: This study aimed to clarify the relationship between balance control systems and falls, and to examine the ability of the Brief-Balance Evaluation Systems Test (BESTest) to evaluate balance deficits in older adults. METHODS: Overall, 109 community-dwelling older adults participated in this study. The history of falls in the last year was investigated. Balance deficits were assessed using the Brief-BESTest, the functional reach test, the Timed up and Go Test, and the one leg balance test. We analyzed the difference between the fallers and non-fallers across two different age groups. RESULTS: Among younger-older group participants (age < 75 years), there were no significant differences between fallers and non-fallers across all variables. Among older-older group participants (age ≥ 75 years), there were significant differences in the Brief-BESTest total (p= .011; fallers, 13.5 versus non-fallers, 17.0) and section IV scores (postural responses of the Brief-BESTest; p= .026, 2.0 versus 5.0). There was no significant difference in other balance measurements. CONCLUSIONS: The postural responses assessed by the Brief-BESTest may serve important functions and may be associated with falls in older adults.

Objectives: The WISH-type S-form hip brace (WISH brace) has significantly improved hip function and functional mobility in patients with hip osteoarthritis (OA). However, most patients later undergo surgery. The main purpose of this study was to evaluate how long the orthosis can be effectively used by patients with hip OA, and to reveal the associated prognostic factors. Methods: This prospective study examined the survival curve of the equipment by using surgery as an endpoint and investigated how the duration of use affects patients. Harris Hip Score, muscle strength, and the Timed Up and Go test (TUG) were evaluated as prognostic factors. Results: By drawing the survival curves of 26 patients, approximately one third were expected to be still using the brace after 7 years. A rapid decrease in use was observed at around 1 year. A significant difference between patients with and without bracing at 1 year was found for the TUG result with the unaffected leg inside (ULI) at the start of bracing. A cut-off value of 9.5 s for the TUG with ULI significantly differentiated patients with and without bracing at 1 year, suggesting a possible predictor of brace survivorship in the early phase. Conclusions: The TUG with ULI with a cut-off value of 9.5 s, or at most 10 s, may be a possible predictor of persistence of brace use in the early phase.
