- * Researchers used a smartphone-based virtual reality system to measure dynamic and static subjective visual vertical (SVV) among 40 older adults, assessing the reliability of these measurements through retests after one week.
- * Results show that the dynamic SVV and visual dependency (VD) had good to excellent test-retest reliability, demonstrating that the smartphone VR method is a portable and effective tool for clinical applications in understanding balance issues in older adults.
Introduction: Artificial intelligence (AI)-based systems using chest images are potentially reliable for diagnosing osteoporosis.
Methods: We performed a systematic review and meta-analysis to assess the diagnostic accuracy of chest X-ray and computed tomography (CT) scans using AI for osteoporosis in accordance with the diagnostic test accuracy guidelines. We included any type of study investigating the diagnostic accuracy of index test for osteoporosis.
Article Synopsis
- - The study reviewed the top 50 influential articles on stroke rehabilitation to analyze factors like citations, publication year, study designs, and research topics, while assessing their evidence levels and methodological quality.
- - It included a focused assessment of the most recent 10 articles (from the past 5 years) to identify any emerging trends in research quality and methodology.
- - Key findings showed that popular topics included noninvasive brain stimulation and robotic rehabilitation, and neither the number of citations nor the citation density correlated with methodological quality, indicating that citations may not be a good measure of research quality.
Peer support, which is given by people with similar life experiences and experiential knowledge, has been shown to be effective for patients with diabetes and mental illness. However, the impact of such peer support on patients coping with heart failure remains indeterminate. The objective of this systematic review and meta-analysis is to scrutinize the potential benefits of peer support for patients with heart failure.

- Systematic reviews (SRs) in orthopedics need better reporting and rigorous methods to provide less biased recommendations, as assessed in a study of 360 SRs from 2012 to 2022.
- Most SRs focused on therapy-related topics, with a notable number authored by researchers from the USA, UK, and China, and only half utilized pairwise meta-analysis.
- Despite improvements in protocol registrations and risk of bias assessments by 2022, adherence to reporting guidelines was low, with poor use of comprehensive search strategies and little evaluation of evidence certainty, indicating a need for greater scrutiny by authors and reviewers.
Introduction: This retrospective cohort study aimed to investigate the effect of rehabilitation and without weekend therapy on Activities of daily living (ADL) and readmission in vertebral fracture patients aged 60 years and older.
Methods: The present study used a hospital-based database created by JMDC Inc. The JMDC hospital-based database is an epidemiological database that has been storing medical claims and Diagnosis Procedure Combination survey data.
Background: Sleep quality in patients with chronic low back pain (CLBP) may affect quality of life (QoL), possibly due to worsening pain, central sensitization (CS), and cognitive factors. However, causal relationship among the factors has not been confirmed yet.
Objective: The purpose of this study was to test the hypothesis that sleep quality in patients with CLBP is attributable to pain, cognitive factors, and CS, and influences QoL, by structural covariance analysis.
Objectives: To investigate the effect of early vestibular rehabilitation on physical function and dizziness in patients with acute vestibular disorders.
Databases Reviewed: The electronic databases examined included PubMed (MEDLINE), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE (via Dialog), and PEDro.
Methods: The inclusion criteria in terms of the study participants were patients 20 years and older with an acute unilateral peripheral vestibular disorder.
Background: Persistent postural-perceptual dizziness (PPPD) is a relatively new disease entity, with diagnostic criteria published by the Bárány Society. PPPD is often preceded by a peripheral or central vestibular disorder. It is not clear how coexisting deficits due to preceding vestibular disorders affect PPPD symptoms.

[Participants and Methods] We enrolled 50 people aged ≥65 years who used long-term care prevention services, interviewed them to determine their fall history during the past year, and divided them into faller and non-faller groups. Gait parameters (velocity, cadence, stride length, foot height, heel strike angle, ankle joint angle, knee joint angle, and hip joint angle) were assessed using the mobile inertial sensors.

- This study aimed to find the best cut-off value of sagittal alignment to identify osteoporotic patients at high risk for fall-related fractures.
- Researchers enrolled 255 women aged 65 and older and measured various factors, ultimately analyzing data from 192 participants over a 3-year follow-up.
- Results showed that the sagittal vertical axis (SVA) was a strong predictor of fractures, with a cut-off value of 100 mm indicating a significantly higher risk.
Objectives: This study investigated the effects of a supervised home-based vestibular rehabilitation program using a booklet on gait function and dizziness in patients with chronic peripheral vestibular hypofunction.
Methods: This was a non-blinded, randomized, controlled trial. Patients (n=42) with chronic peripheral vestibular hypofunction were randomly divided into the vestibular rehabilitation group (VR group; n=20) or the control group (n=22).
Article Synopsis
- The study aimed to determine how the severity of locomotive syndrome (LS) impacts the likelihood of fragility fractures in women with osteoporosis.
- Researchers analyzed data from 315 women over a follow-up period of about 2.8 years, focusing on factors like bone density and LS assessment tests.
- The results indicated that both the sagittal vertical axis and LS severity significantly predicted the occurrence of fragility fractures, suggesting that worsening LS increases fracture risk in osteoporosis patients.
Objective: This study aimed to investigate the prevalence of sarcopenia and factors associated with sarcopenia in patients with dizziness.
Study Design: This is a cross-sectional study.
Patients: A total of 162 patients 65 years or older with the chief complaint of dizziness or vertigo (dizziness group) and 132 community-dwelling elderly (control group) were recruited during their visit to the otolaryngology clinic between May 2020 and October 2021.
[Purpose] This study aimed to compare the effects of different intervention frequencies on walking ability and balance in patients with chronic unilateral vestibular hypofunction. [Participants and Methods] Participants included in this case-control study were assigned to one of two groups: the multiple-intervention (once a week) and single-intervention groups. Results for the Timed Up and Go test, Dynamic Gait Index, Functional Gait Assessment, and Activities-specific Balance Confidence scale were determined at baseline and four weeks after initiating the vestibular rehabilitation program.

Article Synopsis
- Researchers developed a prediction model for skeletal muscle mass index (SMI) using ultrasonography to measure gastrocnemius thickness in older adults, as alternative methods to DXA or BIA are needed.
- The study involved 193 Japanese participants aged 65 and older, collecting data on SMI, subcutaneous fat, gastrocnemius thickness, and other health indicators.
- The resulting equation for predicting SMI included gender, BMI, and gastrocnemius thickness, showing high accuracy and potential as a non-invasive assessment tool for older adults.
Objective: Previous studies have reported that developmental, environmental, medical, psychological, visual, and other sensory-related factors can influence the outcome of vestibular rehabilitation. However, only a few studies have used patient's daily lives as the main outcome. In addition, in some studies, rehabilitation was not supervised by a physical therapist.
