Statistical model of trajectories of reduced mobility in older people with locomotive disorders: a prospective cohort study with group-based trajectory model. BMC Geriatr 2023; 23:699. [PMID: 37904120 PMCID: PMC10617241 DOI: 10.1186/s12877-023-04405-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 10/13/2023] [Indexed: 11/01/2023] Open
Abstract
BACKGROUND Today we experience "Super-aged society", and a drastic increase in the number of older people needing assistance is an urgent matter for everyone from medical and socio-economical standpoints. Locomotive organ dysfunction due to musculoskeletal disorders is one of the main problems in these patients. Although the concepts of frailty and sarcopenia have been proposed for functional decline, pain remains the main and non-negligible complaint in these of such disorders. This prospective cohort study aimed to observe the changes of reduced mobility in patients with locomotive disorders and to determine the risk factors for functional deterioration of those patients using statistical modeling. METHODS A cohort of older adults with locomotive disorders who were followed up every 6 months for up to 18 months was organized. Pain, physical findings related to the lower extremities, locomotive function in performing daily tasks, and Geriatric Locomotive Function Scale-25 (GLFS-25) score were collected to predict the progress of deterioration. Group-based trajectory analysis was used to identify subgroups of changes of GLFS-25 scores, and multinomial logistic regression analysis was performed to investigate potential predictors of the GLFS-25 trajectories. RESULTS Overall, 314 participants aged between 65 and 93 years were included. The participants were treated with various combinations of orthopedic conservative treatments on an outpatient basis. The in-group trajectory model analysis revealed a clear differentiation between the four groups. The mild and severe groups generally maintained their GLFD-25 scores, while the moderate group included a fluctuating group and a no change group. This study showed that comorbidity of osteoporosis was related to GLFS-25 score over 18 months. Age was a weak factor to be moderate or severe group, but gender was not. In addition, the number of pain locations, number of weak muscles, one-leg standing time, grip strength and BMI significantly contributed to the change in GLFS-25 score. CONCLUSIONS This study proposes an effective statistical model to monitor locomotive functions and related findings. Pain and comorbid osteoporosis are significant factors that related to functional deterioration of activities. In addition, the study shows a patient group recovers from the progression and their possible contributing factors.

Abstract
BACKGROUND When treating cancer patients, the progression of symptoms is accompanied by the deterioration of systemic conditions and motor function. From a risk-benefit perspective, a certain level of physical function must be maintained to continue cancer treatment. Recently, outpatient cancer treatment has become more common. Motor function is important to determine the feasibility of continuing cancer treatment. The study aimed to evaluate the motor function of patients with visceral cancer using locomo tests established by Japanese Orthopaedic Association. METHODS Locomo tests were performed, and the results were compared with data from non-cancer individuals. Background data were matched by propensity score matching. Data from 53 cancer patients (group C) were compared with that of 75 non-cancer patients (group N). RESULTS The average score in the two-step test of group C was lower than that of group N (1.27: 1.37, p = 0.004). The average function in the stand-up test of group C was worse than that of group N (p = 0.001). The average score in the 25-question geriatric locomotive function scale (GLFS) of group C was significantly higher than that of group N (19.92: 5.29, SE 2.21, p < 0.001). Higher 25-question GLFS scores indicate reduced mobility. The proportion of the locomo stage 2 in group C was significantly higher than in group N (51%: 13%, p < 0.001). The results of the two field tests revealed a clinically minimal difference between the two groups, but a statistically significant difference. Locomo tests may be detect potential motor dysfunction in outpatient cancer patients with apparently maintained motor function. CONCLUSIONS Even in cancer patients who attend outpatient clinics, their motor functions could be potentially impaired. Therapeutic interventions to maintain and enhance motor function for cancer patients could be useful for continuing cancer treatment, and furthermore, improving prognosis.

Abstract
OBJECTIVES The concept of locomotive syndrome was proposed to highlight older adults who require nursing care services due to the malfunctioning of their locomotive organs. With the coming of a super-aging society, there is a growing need to understand relation between systemic chronic diseases and locomotive syndrome. METHODS We analyzed the second-visit dataset of the Nagahama Study. The association analysis was performed to identify the chronic diseases that were risk factors associated with the occurrence and the progression of locomotive syndrome in both the cross-sectional and longitudinal studies. RESULTS Hypertension, stroke, coronary heart disease, rheumatoid arthritis, chronic renal failure, osteoporosis, anemia, and gastroesophageal reflux disease were independently correlated with locomotive syndrome through the deterioration of body pain, social activity, and cognitive function in the cross-sectional study. Multiple chronic diseases had additive effects and significantly increased the risk of locomotive syndrome. In the longitudinal study, osteoporosis and kidney disease were significantly correlated with the worsening of the total GLFS-25 score. CONCLUSIONS Locomotive syndrome coexisted with various systemic chronic diseases, especially cardiovascular diseases. Osteoporosis and kidney disease were significantly correlated with the progression of locomotive dysfunction. The management of various chronic diseases may be useful to prevent locomotive syndrome and vice versa.

Abstract
BACKGROUND In 2020, the Japanese Orthopaedic Association established a new stage 3 in clinical decision limits (CDL) to evaluate the stage of locomotive syndrome (LS). This study focused on total CDL stage 3 with the aim of investigating indicators related to improvements in total CDL by evaluating the improvement of LS in patients who underwent total hip arthroplasty (THA). METHODS Of the 125 patients who underwent THA at our hospital, the subjects of the analysis were 105 patients determined to be total CDL stage 3 in an evaluation performed before THA. LS was evaluated using the stand-up test, two-step test, and 25-Question Geriatric Locomotive Function Scale (GLFS-25). Indicators related to improvements in total CDL were also investigated. All evaluation items were measured before THA and three months after THA. RESULTS Before THA, all subjects (n = 105) were classified as total CDL stage 3. Three months after THA, improvements in total CDL were seen in 49 subjects (46.7%). The results of stepwise multiple logistic regression analysis showed that the before THA stand-up test and GLFS-25 were significantly related to improvements in total CDL. CONCLUSIONS Three months after THA, improvements in LS were seen in approximately half of the subjects. The stand-up test and GLFS-25 can be used as indicators of improvement in total CDL.

Abstract
BACKGROUND Falling is one of the main reasons for which older adults require nursing care. Locomotive syndrome (LS) predicts the need for nursing care; however, the relationship between falling and LS remains unclarified. This study aimed to determine whether the 5-question Geriatric Locomotive Function Scale (GLFS-5) predicts postoperative fall risk in patients with degenerative cervical myelopathy (DCM). METHODS This study is a post hoc analysis of the data from a prospective cohort of patients undergoing surgery for DCM. Participants recorded their falls in a fall diary from the time of study enrollment (baseline) to 1 year postoperatively. Functional assessments were conducted at baseline, hospital admission for surgery, and 1 year postoperatively. Outcome measures included the GLFS-5, Japanese Orthopaedic Association score, Neck Disability Index, EuroQol 5 Dimensions, and 12-Item Short Form Health Survey. Risk factors for falls were investigated, including previous falls, number of medications, and grip strength. Fallers were divided into two categories: all fallers (≥1 falls), and recurrent fallers (≥2 falls). Variables that were significant in univariate analyses were applied in multiple logistic regression models to adjust for confounders. RESULTS From the initial group of 168 participants, 159 attended the 1-year follow-up, and 132 fall diaries were retrieved and analyzed. Of these 132 patients, 42 (32%) reported at least one fall, while 25 (19%) reported recurrent falls during the postoperative observation period. The GLFS-5 significantly increased from baseline to admission, and significantly decreased from admission to 1 year postoperatively. In multiple logistic regression analysis, the independent predictors of postoperative recurrent falls were previous falls and a higher baseline GLFS-5. The optimal cut-off value of GLFS-5 for predicting all falls/recurrent falls was 12. CONCLUSIONS The GLFS-5 reflected time-dependent functional changes in patients undergoing surgery for DCM. Previous falls and a higher baseline GLFS-5 were independent predictors of postoperative recurrent falls.

Weak hip flexor strength predicts progression of functional capacity decline due to locomotor system dysfunction in community-dwelling older adults: A longitudinal cohort study. Arch Gerontol Geriatr 2021; 97:104499. [PMID: 34375940 DOI: 10.1016/j.archger.2021.104499] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 07/26/2021] [Accepted: 07/26/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE It is critical to determine the risk factors for activities of daily living (ADL) disability caused by locomotor dysfunction. However, no longitudinal study has investigated the association between disability due to locomotive dysfunction and multidimensional factors. Therefore, we investigated the relationship between the progression of functional capacity decline due to locomotive dysfunction and multiple physical functions among older adults in a longitudinal study. METHODS The participants comprised of 433 community-dwelling older adults. Physical function was assessed at baseline, which included handgrip strength, maximal isometric strength of hip flexion, hip extension, hip abduction, knee extension, toe flexion (index for muscle strength), the 5-time chair-stand test (index for muscle power), the one-legged stance and timed ''Up & Go'' tests (index for balance function), the 30-s stair test (index for muscle endurance), and range of motion (ROM) (an index of joint condition). Functional capacity decline due to locomotive dysfunction was assessed using the 25-question Geriatric Locomotive Function Scale (GLFS-25) before and after a 12-month period. Based on changes in the GLFS-25 score compared with baseline, the non-decline and decline groups were operationally defined. Logistic regression analyses with the groups as the dependent variable and physical function as independent variables were performed. RESULTS Of the 433 participants, 189 (43.6%) were included in the decline group. Logistic regression analysis revealed hip flexor strength as a primary determinant in the progression of functional capacity decline. CONCLUSION These results suggest that among physical functions, hip flexor strength influences the progression of disability resulting from locomotive dysfunction in older adults.

[PMID: 34307652 PMCID: PMC8285195 DOI: 10.1155/2021/3919989] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 06/28/2021] [Indexed: 11/18/2022]
Abstract
Purpose The purpose of this study is to investigate the treatment efficacy of total knee arthroplasty (TKA) on locomotive syndrome (LS) focusing on total clinical decision limit (CDL) stage 3 leading to revealing the motor function indicators that can predict LS improvement in knee osteoarthritis patients who had received TKA. Methods This prospective cohort study was conducted in 47 patients evaluated as total CDL stage 3 before TKA who received primary TKA on the operated side and were diagnosed with Kellgren-Lawrence grade 2, 3, or 4 knee osteoarthritis on the nonoperated side. LS was evaluated using stand-up test, two-step test, and 25-Question Geriatric Locomotive Function Scale. In addition, the motor function indicators which could predict the LS improvement were examined. All assessments were conducted before TKA and three months after TKA. Results Of the 47 subjects who were evaluated to be in total CDL stage 3 before TKA, 13 patients (27.7%) were determined to show improvements in total CDL. From the result of the decision tree analysis, when the CDL of the two-step test before TKA was 1 or less, the improvement rate was 83.3%. Even if the CDL of the two-step test before TKA was higher than 1 and if the 3 m-Timed Up and Go test (3m-TUG) before TKA was 9.6 or less, the improvement rate was 50%. Conclusions As of three months after surgery, TKA can improve LS in about 30% of knee osteoarthritis patients. A two-step test before TKA and 3m-TUG before TKA can be used as motor function indicators to predict LS improvement. This study provides useful information for setting the goal for rehabilitation prior to surgery.

Abstract
ABSTRACT Objective: to analyze prevalence and the factors associated with locomotive syndrome in community-dwelling older adults. Method: a cross-sectional study, developed in a municipal center for the care of older adults in Teresina, Piauí, Brazil. The sample was for convenience and comprised 204 older adults aged 60 years or more, of both genders and with preserved cognitive capacity, according to parameters of the Mini Mental State Examination. Data collection occurred from March to November 2018, by applying a form for sociodemographic, clinical and falls occurrence characterization and the 25-item Geriatric Locomotive Function Scale. To measure the strength of the associations between the variables, odds ratios and 95% confidence intervals were adopted. The statistical significance level was set at 5% for the analyses. Results: the prevalence of locomotive syndrome found was 37.2%. The factors associated with the presence of locomotive syndrome were individual monthly income (p=0.005); existence of one of the following comorbidities: systemic arterial hypertension (p=0.039), osteoporosis (p=0.016), arthrosis (p<0.001) or obesity (p=0.014); and history of hospitalization in the last year (p=0.007). Conclusion: the prevalence of locomotive syndrome found in this study was low and presented higher levels in older adults, with an individual monthly income of two to three minimum wages; who reported having hypertension, osteoporosis, arthrosis or obesity; and with a history of hospitalization in the last year. The health condition investigated showed to be related to aging, with significant repercussions on functionality.

Abstract
In this paper, we propose the analysis method for finding out the similarity of the muscle force patterns to mine the risk factor of the anterior cruciate ligament (ACL) injury. Akaike information criteria (AIC) under the assumption of the auto-regression model is adapted to analyze the similarities of muscle force patterns in time-series. The difference of AIC values between 2 muscles is considered to be the distance between 2 muscle force patterns and the dexterity of the maneuver is expected to be discussed. We measured drop vertical jump (DVJ) and use the data around the contact timing of whom hadn't had ACL injury experiments. The results showed that we could successfully calculate AIC distance according to the similarity of the time-series data pattern and it can be useful to discuss one's dexterity of controlling body maneuvers soon after contact timing of DVJ motion.

Abstract
Background The 25-question Geriatric Locomotive Function Scale (GLFS-25) is widely used in daily clinical practice in evaluating locomotive syndrome (LS). The questionnaire contains 25 questions aiming to describe 6 aspects, including body pain, movement-related difficulty, usual care, social activities, cognitive status, and daily activities. However, its potential underlying latent factor structure of the questionnaire has not been fully examined so far. Methods Five hundred participants who were 60 years or older and were able to walk independently with or without a cane but had complaints of musculoskeletal disorders were recruited face to face at the out-patient ward of Aichi Medical University Hospital between April 2018 and June 2019. All participants completed the GLFS-25. Confirmatory factor analysis (CFA) models (single-factor model, 6-factor model as designed by the developers of the GLFS-25) were fitted and compared using Mplus 8.3 with a maximum likelihood minimization function. Modification indices, standardized expected parameter change were used, a standard strategy for scale development was followed in the search for an alternative and simpler model that could well fit the collected data. Cronbach’s α and its 95% confidence interval (CI) were also calculated. Results Mean (standard deviation) participants age was 72.6 (7.4) years old; 63.6% of them were women. Under the current criteria, 132 (26.4%) and 262 (52.4%) of the study subjects would be classified as LS stage 1 and stage 2, respectively. Overall, the Cronbach’s α (95% CI) for GLFS-25 evaluated using these data was 0.959 (0.953, 0.964). The single- and 6-factor models were rejected due to poor fit. The alternative models with either full 25 questions or a shortened GLFS-16 were found to fit the data better. These alternative models included three latent factors (body pain, movement-related difficulty, and psycho-social complication) and allowed for cross-loading and residual correlations. Discussion The findings of the CFA models provided evidence that the factor structure of the GLFS-25 might be simpler than the 6-factor model as suggested by the designers. The complex relationships between the latent factors and the observed items may also indicate that individual sub-scale use or simply combining the raw scores for evaluation is likely to be inadequate or unsatisfactory. Thus, future revisions of the scoring algorithm or questions of the GLFS-25 may be required.

Abstract
Purpose Aging of society has increased the need for prolongation of a healthy lifespan through maintenance of physical function. Prediction of future physical function may be possible by screening for stage 1 locomotive syndrome (LS). In this prospective study, we examined the influence of LS stage 1 at baseline (2011) on physical performance after 5 years (2016) in a community-dwelling cohort. Methods The participants were elderly adults aged >40 years who attended public health checkups as part of the Yakumo Study. LS screening in 2011 and 2016 was performed using the 25-question geriatric locomotive function scale (GLFS-25), the stand-up test, and the two-step test. LS of stage 1 or 2 was defined if the participant met the criteria in any of the three tests. Participants not meeting LS criteria were defined as the no risk group. Physical performance tests (10 m gait time, back muscle strength, 3 m TUG, and maximum stride) were also performed in 2011 and 2016. Results A total of 113 subjects (49 males, 64 females; average age 65.0 years) were followed from 2011 to 2016. At baseline, 73 (65%) had no risk, 29 (25%) had stage 1 LS, and 11 (10%) had stage 2 LS. Five years later, 51 (45%) had no risk, 45 (40%) had stage 1 LS, and 17 (15%) had stage 2 LS. Of the 73 subjects with no risk at baseline, 23 (32%) had stage 1 LS and 1 (1%) had stage 2 LS after 5 years. The baseline stage 1 LS group had significantly worse physical performance after 5 years, compared to the baseline no risk group (p < 0.05). Conclusions This longitudinal study showed that stage 1 LS screening is important for prevention of motor dysfunction in middle-aged and elderly people.

Angiotensin 1-7 alleviates aging-associated muscle weakness and bone loss, but is not associated with accelerated aging in ACE2-knockout mice. Clin Sci (Lond) 2019; 133:2005-2018.

Abstract
The angiotensin-converting enzyme 2 (ACE2)-angiotensin 1-7 (A1-7)-A1-7 receptor (Mas) axis plays a protective role in the renin-angiotensin system (RAS). We recently found that ACE2 knockout (ACE2KO) mice exhibit earlier aging-associated muscle weakness, and that A1-7 alleviates muscle weakness in aging mice. In the present study, we investigated the role of the A1-7-Mas pathway in the effect of ACE2 on physiological aging. Male wild-type, ACE2KO, and Mas knockout (MasKO) mice were subjected to periodical grip strength measurement, followed by administration of A1-7 or vehicle for 4 weeks at 24 months of age. ACE2KO mice exhibited decreased grip strength after 6 months of age, while grip strength of MasKO mice was similar to that of wild-type mice. A1-7 improved grip strength in ACE2KO and wild-type mice, but not in MasKO mice. Muscle fibre size was smaller in ACE2KO mice than that in wild-type and MasKO mice, and increased with A1-7 in ACE2KO and WT mice, but not in MasKO mice. Centrally nucleated fibres (CNFs) and expression of the senescence-associated gene p16INK4a in skeletal muscles were enhanced only in ACE2KO mice and were not altered by A1-7. ACE2KO mice, but not MasKO mice, exhibited thinning of peripheral fat along with increased adipose expression of p16INK4a A1-7 significantly increased bone volume in wild-type and ACE2KO mice, but not in MasKO mice. Our findings suggest that the impact of ACE2 on physiological aging does not depend on the endogenous production of A1-7 by ACE2, while overactivation of the A1-7-Mas pathway could alleviate sarcopenia and osteoporosis in aged mice.

Abstract
To evaluate the association between vision-related quality of life (QoL), physical inactivity, and locomotor dysfunction in subjects with visual impairment.This cross-sectional study included 215 visually impaired subjects recruited from six ophthalmology departments in Japan. The physical inactivity and locomotor dysfunction associated with their visual impairment was investigated. The physical activity level was assessed using the short form of the International Physical Activity Questionnaire and classified as high, moderate, or low. Locomotor function was evaluated with the Geriatric Locomotive Function Scale. Vision-related QoL was evaluated using the 25-item National Eye Institute Visual Function Questionnaire. Background data, including for age, sex, best-corrected visual acuity for each eye, causative eye diseases, systemic comorbidities, and body mass index, were also collected.The average patient age was 69.6 (range, 20-93 years; standard deviation, 14.5 years) and 118 patients (54.9%) were men. Multivariate analysis showed that vision-related QoL and best-corrected visual acuity in the worse eye were significantly associated with physical inactivity and that vision-related QoL, female sex, age, and presence of systemic comorbidity were significantly associated with locomotor dysfunction. Vision-related quality of life is associated with physical inactivity and locomotor dysfunction.

Abstract
The deterioration of locomotive components, which comprise bones, joints, and intervertebral discs, and muscles and nerves, can lead to symptoms such as pain, limitations in the range of joint mobility, malalignment, impaired balance, and difficulty walking. Locomotive syndrome (LoS) was proposed by the Japanese Orthopedic Association in 2007 as a concept for people who are at a high risk of developing a musculoskeletal ambulation disability attributed to locomotor organs. Although many international articles related to LoS have been published, an international consensus of this concept seems to be lacking. This review article on LoS introduces the concept, the related assessment methods, and the condition's prevalence based on the most up-to-date literature, and discusses discrimination from frailty and sarcopenia, relevance to musculoskeletal problems, management plan, and future directions. Familiarity with recent evidence would be useful for the health care providers in an aging society to educate individuals with LoS or pre-LoS and to maintain their well-being and prevent them from requiring long-term care.

Abstract
OBJECTIVES To investigate the distribution of 25-question Geriatric Locomotive Function Scale (GLFS-25) scores in Japanese rheumatoid arthritis (RA) patients and evaluate relationships with clinical variables. METHODS Among 15,115 patients registered in the NinJa database for fiscal year 2015, 1710 with complete GLFS-25 and disease activity score-28 (DAS28) data were analyzed. Correlations between GLFS-25 score and clinical variables were assessed by Spearman coefficients. Mean GLFS-25 scores were compared among DAS28 groups (<2.6, 2.6-3.1, 3.2-5.0, ≥5.1) using the Kruskal-Wallis test. To evaluate the performance of the GLFS-25 and Health Assessment Questionnaire Disability Index (HAQ-DI) for predicting DAS28 ≥ 3.2 (moderate/high disease activity), receiver operator characteristic (ROC) curves were constructed. RESULTS GLFS-25 score was significantly correlated with age, disease duration, DAS28, and HAQ-DI. GLFS-25 score increased in parallel with DAS28. The proportion of patients with locomotive syndrome stage 2 also increased with DAS28. Area under the curve values for HAQ-DI and GLFS-25 score were 0.739 and 0.768, respectively. At a GLFS-25 positive cutoff score ≥16, sensitivity was 0.716 and specificity was 0.661 for predicting DAS28 ≥ 3.2. CONCLUSION This study documents the GLFS-25 score distribution in Japanese RA patients and demonstrates that GLFS-25 is a useful measure for evaluating functional ability in RA.

Abstract
High-Fat-Diet (HFD)-induced obesity is a major contributor to heart and mobility premature aging and mortality in both Drosophila and humans. The dSir2 genes are closely related to aging, but there are few directed reports showing that whether HFD could inhibit the expression dSir2 genes. Endurance exercise can prevent fat accumulation and reverse HFD-induced cardiac dysfunction. Endurance also delays age-relate functional decline. It is unclear whether lifetime endurance exercise can combat lifetime HFD-induced heart and mobility premature aging, and relieve the harmful HFD-induced influence on the dSir2 gene and lifespan yet. In this study, flies are fed a HFD and trained from when they are 1 week old until they are 5 weeks old. Then, triacylglycerol levels, climbing index, cardiac function, lifespan, and dSir2 mRNA expressions are measured. We show that endurance exercise improves climbing capacity, cardiac contraction, and dSir2 expression, and it reduces body and heart triacylglycerol levels, heart fibrillation, and mortality in both HFD and aging flies. So, lifelong endurance exercise delays HFD-induced accelerated age-related locomotor impairment, cardiac dysfunction, death, and dSir2 expression decline, and prevents HFD-induced premature aging in Drosophila.

Abstract
BACKGROUND Ageing is associated with a decline of motor function and ability to perform daily activities. Locomotive disorders are one of the major disorders resulting in adverse health condition in elderly people. Concept of Locomotive syndrome (LoS) was proposed to tackle the problems and prolong healthy life expectancy of people with locomotive disorders. To develop intervention strategy for LoS it is mandatory to investigate impairments, functional disabilities which people with locomotive disorder experience and to examine relationships among these parameters. For this purpose we have developed Geriatric Locomotive Function Scale-25 (GLFS-25). Though several physical performance tests were reported for identification or monitoring the severity of LoS, there are few studies reported on characteristics of disability which people with locomotive disorders experience. The aim of this study was to report the characteristics of ADL disabilities in elderly people with locomotive disorders in terms of numbers and degree of activity limitations. METHODS We organized a cohort study and recruited 314 participants aged 65 years and over from five orthopedic clinics or nursing care facilities. This was a cross-sectional study to use the baseline data of such cohort. ADL disabilities were assessed using GLFS-25 scale arranging the GLFS-25 scores in ordinal levels using "R language" program. Numbers and degrees of activity limitations were determined and compared among the levels. Frequency of limitation in activities regarding social activity, housework, locomotion, mobility and self-care was compared among across the disability level. RESULTS The GLFS-25 score was mathematically categorized into 7 levels. The number of activity limitations and the degrees of each activity limitation were significantly greater in high GLFS-25 levels than in low levels. Difficulties in mobility appeared in less severe level, difficulties in domestic and social life appeared in moderately severe level, and difficulties in self-care appeared in advanced level. CONCLUSIONS High GLFS-25 score represented high degree of disability on ADLs. Concordant increase of numbers of activity limitation and severity progression in activity limitation may contribute to progression of disability. Activity limitation may occur in the following order: sports activity, walking, transferring, and self-care.

Abstract
BACKGROUND Locomotive disorders are one of the main causative pathologies for the condition requiring assistance on activities of daily living (ADL). Although psychological concerns such as feeling of depression and anxiety are prevalent in elderly people, the causal relation among motor function, ADL disability, and psychological concerns is controversial. PURPOSE Purpose of this study was to investigate causal relationship among motor function, ADL disability, and psychological concerns in elderly people with locomotive disorders. METHODS The data for this study were from a community-dwelling sample of 314 elderly persons with locomotive disorders aged 65 and older who visited orthopedic clinics and/or affiliated institutions. Motor function was assessed by one-leg standing time with eyes open, leg extension power and grip power. We assessed ADL disability using the 25-question Geriatric Locomotive Function Scale (GLFS-25), and psychological concerns by three self-reported questions. We constructed two models and tested fitness of the models to the data using a structural equation modeling (SEM). Model 1: motor function affects ADL disability and ADL disability affects psychological concerns, Model 2: motor function affects psychological concerns and psychological concerns affects ADL disability. RESULTS The fit indices were chi-square = 23.152 (p = 0.081), RMSEA = 0.042, GFI = 0.981, AGFI = 0.955, CFI = 0.987 for Model 1, and chi-square = 84.583 (p < 0.001), RMSEA = 0.119, GFI = 0.935, AGFI = 0.854, CFI = 0.892 for Model 2. These fit indices indicated a good fit of the model 1 and inadequate fit of model 2 to the data. CONCLUSION Decline of motor function contributed toward psychological concerns via ADL disability in elderly people with locomotive disorders.
