Purpose: Impairment of postural control is common in people with COPD. However, the precise characteristics of this alteration are not clearly known. The “Systems Framework for Postural Control” which define postural control sub-components, represents an interesting tool to explore this field. The main aim of this review was to identify which postural control sub-components are impaired in people with COPD and to summarise characteristics for each sub-component. A secondary aim was to precise the relation between postural control and activities of daily living (ADL). Materials and methods: A scoping review was conducted, according to the JBI methodology. Medline, Cochrane Library, Scielo, Google Scholar, OpenGrey, and HAL were searched from inception to May 2022. The search was performed in English and French. Results: Eighty-nine articles were included. There was evidence of a potential impairment for most of the postural control sub-components. Characteristics of every sub-component alteration were heterogeneous. Reduced postural control could be associated with difficulties in ADL. Conclusions: People with COPD may have impairment in a wide range of postural control sub-components. Further research is needed to clarify if a common pattern of modification exits for this alteration and to precise the link with ADL.

Purpose: Postural control impairment has been identified as a potential extrarespiratory manifestation in patients with chronic obstructive pulmonary disease (COPD). The aims of this study were to identify clinical factors that characterize patients with reduced postural control, to examine the correlation between clinical factors and postural control and to determine predictors of an impaired postural control among COPD participants enrolled in a pulmonary rehabilitation (PR) program. Methods: This study is a secondary analysis of an observational study (PARACHUTE). The baseline assessment of the PR program was used for the analysis. Postural control impairment was defined using the Brief BESTest score (BBT). Results: Participants (n = 73) were included in the analysis, 43 of them were classified in the reduced postural control group. The between-group comparison (non-reduced vs reduced postural control) identified differences for partial pressure in oxygen (PaO ₂), Saint George Respiratory Questionnaire (SGRQ) total score and subscores (SGRQ-Symptoms, SGRQ-Activities, and SGRQ-Impact), COPD assessment test (CAT), and anxiety score of the Hospital Anxiety and Depression Scale. The BBT score was significantly correlated with maximal inspiratory pressure (MIP), SGRQ, SGRQ-Symptoms, SGRQ-Impact, Falls Efficacy Scale, modified Medical Research Council Scale, 6-min walk test, and PaO ₂. Logistic regression identified SGRQ-Symptoms, PaO ₂, MIP, and body mass index (BMI) as predictors of the presence of reduced postural control. Conclusion: Low quality of life (QoL) and PaO ₂ and high anxiety seem to be discriminative characteristics of patients with COPD with reduced postural control. Furthermore, QoL, PaO ₂, inspiratory muscle strength, and BMI seem to be acceptable predictors of the presence of postural control impairment.

The interaction between oral and/or mental cognitive tasks and postural control and mobility remains unclear. The aim of this study was to analyse the influence of speech production and cognitive load levels on static balance and timed up and go (TUG) during dual-task activities. Thirty healthy young subjects (25 ± 4 years old, 17 women) participated in this study. A control situation and two different cognitive arithmetic tasks were tested: counting backward in increments of 3 and 7 under oral (O) and mental (M) conditions during static balance and the TUG. We evaluated the dual-task cost (DTC) and the effect of speech production (SP) and the level of cognitive load (CL) on these variables. There was a significant increase in the centre of pressure oscillation velocity in static balance when the dual task was performed orally compared to the control situation The DTC was more pronounced for the O than for the M. The SP, but not the CL, had a significant effect on oscillation velocity. There was an increase in TUG associated with the cognitive load, but the mental or oral aspect did not seem to have an influence. Mobility is more affected by SP when the cognitive task is complex. This may be particularly important for the choice of the test and understanding postural control disorders.

Purpose Impairment of postural control is a common extra-respiratory manifestation in people with COPD. However, the precise characteristics of this alteration are not clearly known. The “Systems Framework for Postural Control” which define postural control sub-components, is a relevant tool to explore this field.

A secondary aim was to precise the relation between postural control and activities of daily living. Materials and methods A scoping review was conducted, according to the JBI methodology. Pubmed, Cochrane Library, Scielo, Google Scholar, Open Grey and HAL were searched from inception to March 2021. The search was performed in English and French. Results Seventy-seven articles were included. There was evidence of a potential impairment for most of the postural control sub-components. Characteristics of every sub-component alteration were heterogeneous. Even if the relation was poorly studied, reduced postural control seemed to be associate with difficulties in activities of daily living. Conclusion Patients with COPD could experiment impairment among a wide range of postural control sub-components. Future research must clarify if a common pattern of modification exits for this alteration. Implications for rehabilitation Impairment of postural control is a common extra-respiratory manifestation in patients with COPD and so clinicians must include it in their clinical reasoning Numerous postural control sub-components could be altered in patients with COPD, suggesting that postural control assessment must be holistic. This scoping review shows that characteristics of postural control impairment are varied and that there may be no common pattern at the COPD population level.

Background: Chronic obstructive pulmonary disease (COPD) is a common respiratory disease and is associated with the presence of numerous comorbidities. Among these, impaired postural control has been reported to be common in this population. However, postural control has not been extensively studied in tasks of daily living in this population. Novel solutions for postural control assessment exist, like the quantitative motion analysis, which has demonstrated to be a robust and accurate tool. Objective: the main aim of this study is to characterize the postural control of COPD patients during tasks of daily living compared to that of control subjects using quantitative motion analysis. The secondary aims of this study are to examine the associations between postural control variables of interest and various clinical factors and to investigate the utility of the modified Glittre-ADL for the clinical assessment of postural control in daily task. Method: A case-control study will be conducted with a group of sixteen COPD patients and a control group of sixteen participants. Quantitative movement analysis will be used to assess postural control during a modified Glittre-ADL test (incorporating tasks of daily living) and timed-up-and-go tests (under normal and dual-task conditions). Clinical factors (e.g., dyspnea, pain, inspiratory muscle strength, falls, fear of falling, etc.) will also be assessed. Discussion: ATTRACTION will be the first study to propose the assessment of postural control in various daily living tasks in COPD patients using quantitative movement analysis and has the potential to precise the relation between postural control and several clinical factors.

The aim of this work was to identify and characterize the measures employed for assessing postural control in randomized controlled trials (RCTs) of balance interventions in older adults with the reference to the Systems Framework for Postural Control. A scoping review was conducted, and RCTs of balance interventions in older adults published from 2013 to March 2023 were considered for inclusion. Two hundred and seventy-one studies were included with a total of 49 different measures used; the Timed Up and Go test being the most commonly employed. The median number of components of postural control assessed per study was five. The most frequently assessed components were motor systems and static stability, while reactive postural control, cognitive influences and verticality were the least frequently assessed. Postural control in RCTs of balance in older adults was assessed using a wide range of measures, but also from the perspective of a limited number of components.
