Abstract
Background The Timed 360° turn test (T-360° TT) was developed to assess balance and turning ability. Although validity and reliability have been performed in different diseases, validity and reliability have not been performed in individuals with ankle sprain (AS). Purpose The purpose of this study was to investigate the validity and reliability of the T-360° TT in individuals with AS. Methods The study included 54 individuals with AS. Participants were initially evaluated with T-360° TT, Timed Up and Go (TUG) test and Biodex Balance System (BBS). To assess test-retest reliability, the T-360° TT was performed again 5 days after the first measurement by the same assessor. Results At the end of the study, strong positive correlations were found between T-360° TT with TUG test and BBS (p < 0.05). In addition, T-360° TT had excellent test-retest reliability (Intraclass correlation coefficient = 0.87). Conclusion The T-360° TT is a valid and reliable tool for the evaluation of balance and turning ability in individuals with AS. We also think that it can be used practically in clinical settings because it is a test that can be easily and quickly performed.

Abstract
PURPOSE The aim of this study is to determine whether the 360° turn test is a reliable and valid evaluator that can be used to assess dynamic balance in patients with early (radiographic grades I and II) and advanced (radiographic grades III and IV) knee osteoarthritis. MATERIALS AND METHODS This study is a methodological research. For the test time and step count of 360° turn test; test-retest reliability were determined by calculating the intraclass correlation coefficient and concurrent validity in patients with knee osteoarthritis was investigated by correlation with the timed up and go test time. RESULTS The final analysis was made on 117 participants. The intraclass correlation coefficient values for the test time and step count of 360° turn test in patients with early knee osteoarthritis are 0.931 and 0.902, respectively, while they are 0.923 and 0.943 in patients with advanced knee osteoarthritis. The Pearson correlation coefficients between the time and step count of 360° turn test and the test time of the timed up and go test in patients with early knee osteoarthritis, respectively; while they are 0.547 and 0.388, the correlation in patients with advanced knee osteoarthritis are 0.697 and 0.700, respectively (p < 0.01). CONCLUSIONS The 360° turn test is a evaluator that has excellent test-retest reliability and moderate to strong concurrent validity in patients with both early and advanced knee osteoarthritis and can be used in the assessment of dynamic balance in this population.

Abstract
BACKGROUND Turning in place is a challenging motor task and is used as a brief assessment test of lower limb function and dynamic balance. This review aims to examine how research of instrumented analysis of turning in place is implemented. In addition to reporting the studied population, we covered acquisition systems, turn detection methods, quantitative parameters, and how these parameters are computed. METHODS Following the development of a rigorous search strategy, the Web of Science and Scopus were systematically searched for studies involving the use of turning-in-place. From the selected articles, the study population, types of instruments used, turn detection method, and how the turning-in-place characteristics were calculated. RESULTS Twenty-one papers met the inclusion criteria. The subject groups involved in the reviewed studies included young, middle-aged, and older adults, stroke, multiple sclerosis and Parkinson's disease patients. Inertial measurement units (16 studies) and motion camera systems (5 studies) were employed for gathering measurement data, force platforms were rarely used (2 studies). Two studies used commercial software for turn detection, six studies referenced previously published algorithms, two studies developed a custom detector, and eight studies did not provide any details about the turn detection method. The most frequently used parameters were mean angular velocity (14 cases, 7 studies), turn duration (13 cases, 13 studies), peak angular velocity (8 cases, 8 studies), jerkiness (6 cases, 5 studies) and freezing-of-gait ratios (5 cases, 5 studies). Angular velocities were derived from sensors placed on the lower back (7 cases, 4 studies), trunk (4 cases, 2 studies), and shank (2 cases, 1 study). The rest (9 cases, 8 studies) did not report sensor placement. Calculation of the freezing-of-gait ratio was based on the acceleration of the lower limbs in all cases. Jerkiness computation employed acceleration in the medio-lateral (4 cases) and antero-posterior (1 case) direction. One study did not reported any details about jerkiness computation. CONCLUSION This review identified the capabilities of turning-in-place assessment in identifying movement differences between the various subject groups. The results, based on data acquired by inertial measurement units across studies, are comparable. A more in-depth analysis of tests developed for gait, which has been adopted in turning-in-place, is needed to examine their validity and accuracy.

Balance telerehabilitation and wearable technology for people with Parkinson's disease (TelePD trial). BMC Neurol 2023; 23:368. [PMID: 37833645 PMCID: PMC10571293 DOI: 10.1186/s12883-023-03403-3] [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: 09/16/2023] [Accepted: 09/26/2023] [Indexed: 10/15/2023] Open
Abstract
BACKGROUND Balance impairments, that lead to falls, are one of the main symptoms of Parkinson's disease (PD). Telerehabilitation is becoming more common for people with PD; however, balance is particularly challenging to assess and treat virtually. The feasibility and efficacy of virtual assessment and virtual treatment of balance in people with PD are unknown. The present study protocol has three aims: I) to determine if a virtual balance and gait assessment (instrumented L-shape mobility test) with wearable sensors can predict a gold-standard, in-person clinical assessment of balance, the Mini Balance Evaluation Systems Test (Mini-BESTest); II) to explore the effects of 12 sessions of balance telerehabilitation and unsupervised home exercises on balance, gait, executive function, and clinical scales; and III) to explore if improvements after balance telerehabilitation transfer to daily-life mobility, as measured by instrumented socks with inertial sensors worn for 7 days. METHODS The TelePD Trial is a prospective, single-center, parallel-group, single-blind, pilot, randomized, controlled trial. This trial will enroll 80 eligible people with PD. Participants will be randomized at a 1:1 ratio into receiving home-based balance exercises in either: 1) balance telerehabilitation (experimental group, n = 40) or 2) unsupervised exercises (control group, n = 40). Both groups will perform 12 sessions of exercise at home that are 60 min long. The primary outcome will be Mini-BESTest. The secondary outcomes will be upper and lower body gait metrics from a prescribed task (instrumented L-shape mobility test); daily-life mobility measures over 7 days with wearable sensors in socks, instrumented executive function tests, and clinical scales. Baseline testing and 7 days of daily-life mobility measurement will occur before and after the intervention period. CONCLUSION The TelePD Trial will be the first to explore the usefulness of using wearable sensor-based measures of balance and gait remotely to assess balance, the feasibility and efficacy of balance telerehabilitation in people with PD, and the translation of balance improvements after telerehabilitation to daily-life mobility. These results will help to develop a more effective home-based balance telerehabilitation and virtual assessment that can be used remotely in people with balance impairments. TRIAL REGISTRATION This trial was prospectively registered on ClinicalTrials.gov (NCT05680597).

Abstract
PURPOSE Falls are the leading cause of injury and premature death among community dwelling elderly but can be prevented through comprehensive balance rehabilitation which ideally targets the patient's specific needs. In this study, we evaluate the reliability and agreement of six novel clinical measures of different balance domains which applied in a patient-specific balance profile guides exercise prescription in balance rehabilitation. MATERIALS AND METHODS The intra-rater reliability and agreement of the six measures were evaluated on the same day in six different cohorts of elderly with balance disability (n = 65-100). Further, the inter-day intra-rater and inter-rater and test-retest reliability and agreement of the measures and the balance profile were evaluated (n = 100). RESULTS The intra-day intra-rater reliability and agreement was moderate to excellent (ICC2.1 = 0.525-0.968, with SDC% = 6.5-284.9%) but poor to good for the inter-day conditions (ICC2.1 = 0.123-0.832, with SDC% = 6.6-229.2%). The reliability of classifying the lower domain in the balance profile was fair, with kappa = 0.56 (95%CI 0.36-0.76). CONCLUSIONS Five of the six measures may reliably be applied to measure balance disability and to guide rehabilitation. Implications for rehabilitationBalance disability is the primary reason for accidental falls among elderly but can be prevented through comprehensive individualized balance rehabilitation.Specific Training According to BaLance Evaluation (STABLE) is a novel approach for designing effective balance exercises based on clinical measurements.Five of the six measures are reliable when applied in a patient-specific balance profile to guide rehabilitation following the STABLE approach.

Abstract
Digital health technologies enable remote and therefore frequent measurement of motor signs, potentially providing reliable and valid estimates of motor sign severity and progression in Parkinson’s disease (PD). The Roche PD Mobile Application v2 was developed to measure bradykinesia, bradyphrenia and speech, tremor, gait and balance. It comprises 10 smartphone active tests (with ½ tests administered daily), as well as daily passive monitoring via a smartphone and smartwatch. It was studied in 316 early-stage PD participants who performed daily active tests at home then carried a smartphone and wore a smartwatch throughout the day for passive monitoring (study NCT03100149). Here, we report baseline data. Adherence was excellent (96.29%). All pre-specified sensor features exhibited good-to-excellent test–retest reliability (median intraclass correlation coefficient = 0.9), and correlated with corresponding Movement Disorder Society–Unified Parkinson's Disease Rating Scale items (rho: 0.12–0.71). These findings demonstrate the preliminary reliability and validity of remote at-home quantification of motor sign severity with the Roche PD Mobile Application v2 in individuals with early PD.

Abstract
BACKGROUND Lack of participation of black and minority ethnic communities (BAME) in registered clinical trials is a concern as data emerging from these studies are used to licence new drugs or other interventions, even though findings made in such selected study populations have limited external validity in the aforesaid ethnic groups. OBJECTIVE We used Parkinson's disease (PD), the fastest rising neurodegenerative disorder in the world, as an exemplar condition to test our hypothesis that participants from BAME communities are underrepresented in clinical trials. METHODS A systematic search of clinical trials registered on a Clinicaltrials.gov database which queried for PD with racial distribution data from 2017 to 2021. RESULTS Out of 266 trials considered, 54 trials were published in peer reviewed journals. Among these, only 23 (42.65%) publications reported data regarding the racial distribution of the participants. Out of these, five studies involved mixed racial participation and two trials included black subjects. CONCLUSION We found that inclusion of under-represented BAME groups in recently published clinical trials is low, at only 21.57%, and is not even considered in most studies. Out of the reviewed trials, only 5 (21.75%) studies reported detailed demographic categories with black minorities enrolment. This constitutes a severe under-representation when compared to the proportion of Black or African American in the UK population (3%). Results of this study identified the need for better reporting of racial composition in clinical trials. We strongly recommend that future studies should consider ethnicity and other issues around diversity when designing and implementing the clinical trials, not only in the PD field but also beyond.

Abstract
BACKGROUND Frailty is a common geriatric syndrome and is characterized by decreased physiological reserve and increased vulnerability towards adverse health outcomes including falls. Turning is a challenging task and is reported to be one of the daily activities that leads to falling in older populations. RESEARCH QUESTION Does 180° walking turns and 360° turning on the spot differ among frail, pre-frail, and non-frail older adults? Can 180° walking turns and 360° turning on the spot cutoffs discriminate older adults with frailty from those without? METHODS A cross-sectional study was conducted on community-dwelling older adults aged over 65 years. Frailty was assessed using Fried's phenotype method, and turning tasks were measured by inertial sensors. The turn duration (s) and angular velocity (°/s) were recorded for analysis. RESULTS In total, 109 participants were enrolled including 50 pre-frail and 12 frail individuals. Frail older adults took significantly longer and had slower angular velocities to complete the 180° and 360° turning than did either pre-frail (p = 0.002 and p < 0.001, respectively) or non-frail (p = 0.03 and p < 0.001, respectively) older adults. Cutoff times of 2.45 and 3.46 s were found to best discriminate frail people from those without frailty in both the 180° (sensitivity 83.3 %, specificity 71.1 %, area under the receiver operating characteristic curve (AUC) 0.796) and 360° (sensitivity 91.7 %, specificity 74.2 %, AUC 0.857) turn tasks. SIGNIFICANCE Older individuals with frailty syndrome had difficulty turning as evidenced by a longer turning duration and a slower angular velocity. The turn duration could be a potential biomarker of frailty in older populations. Assessing the turning performance can facilitate early detection of the onset of frailty and inform early prevention and rehabilitation interventions in clinical practice.
