Electrocortical activity associated with movement-related fear: a methodological exploration of a threat-conditioning paradigm involving destabilising perturbations during quiet standing. Exp Brain Res 2024; 242:1903-1915. [PMID: 38896295 PMCID: PMC11252179 DOI: 10.1007/s00221-024-06873-0] [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: 03/08/2024] [Accepted: 06/12/2024] [Indexed: 06/21/2024]
Abstract
Musculoskeletal trauma often leads to lasting psychological impacts stemming from concerns of future injuries. Often referred to as kinesiophobia or re-injury anxiety, such concerns have been shown to hinder return to physical activity and are believed to increase the risk for secondary injuries. Screening for re-injury anxiety is currently restricted to subjective questionnaires, which are prone to self-report bias. We introduce a novel approach to objectively identify electrocortical activity associated with the threat of destabilising perturbations. We aimed to explore its feasibility among non-injured persons, with potential future implementation for screening of re-injury anxiety. Twenty-three participants stood blindfolded on a translational balance perturbation platform. Consecutive auditory stimuli were provided as low (neutral stimulus [CS-]) or high (conditioned stimulus [CS+]) tones. For the main experimental protocol (Protocol I), half of the high tones were followed by a perturbation in one of eight unpredictable directions. A separate validation protocol (Protocol II) requiring voluntary squatting without perturbations was performed with 12 participants. Event-related potentials (ERP) were computed from electroencephalography recordings and significant time-domain components were detected using an interval-wise testing procedure. High-amplitude early contingent negative variation (CNV) waves were significantly greater for CS+ compared with CS- trials in all channels for Protocol I (> 521-800ms), most prominently over frontal and central midline locations (P ≤ 0.001). For Protocol II, shorter frontal ERP components were observed (541-609ms). Our test paradigm revealed electrocortical activation possibly associated with movement-related fear. Exploring the discriminative validity of the paradigm among individuals with and without self-reported re-injury anxiety is warranted.

Is it Possible to Reduce Pain-Related Fear in Individuals with Knee Osteoarthritis? a Systematic Review of Randomised Clinical Trials. Physiother Theory Pract 2023; 39:1106-1132. [PMID: 35200089 DOI: 10.1080/09593985.2022.2038743] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 11/26/2021] [Accepted: 01/07/2022] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To evaluate the effectiveness of different interventions in reducing pain-related fear outcomes in people with knee osteoarthritis who have or have not had previous knee surgery, and to analyze whether included trials reported their interventions in full detail. METHODS Systematic searches were carried out in the Cochrane CENTRAL, CINAHL, EMBASE, PEDro, PsycINFO, PubMed, and SPORTDiscus from the inception of the database up to November 2019. Searches were manually updated to July 2021. We included randomized clinical trials that evaluated pain-related fear outcomes as a primary or secondary outcome in adults with knee osteoarthritis. The Cochrane Risk of Bias Tool 2 and the GRADE approach evaluated the risk of bias and the certainty of the evidence, respectively. RESULTS Eighteen trials were included. Four trials evaluated pain-related fear as a primary outcome and all evaluated kinesiophobia in samples that had previously undergone a knee surgical procedure. These trials found that interventions based primarily on cognitive aspects (e.g. cognitive-behavioral principles) can be effective in reducing kinesiophobia. Trials evaluating pain-related fear as the secondary outcome also found that interventions that included cognitive aspects (e.g. pain neuroscience education) decreased the levels of pain-related fear (e.g. fear of falling or kinesiophobia) in patients with or without a previous knee surgery. However, serious to very serious risk of bias and imprecisions were found in included trials. Thus, the certainty of the evidence was judged as low and very low using the GRADE approach. All trials reported insufficient details to allow a complete replication of their interventions. CONCLUSIONS Interventions that include cognitive aspects may be the best option to reduce pain-related fear in people with knee osteoarthritis. However, we found a general low and very low certainty of the evidence and the findings should be considered with caution.

Abstract
OBJECTIVE To identify distinct trajectories of lack of knee confidence over an 8-year follow-up period and to examine baseline factors associated with poor trajectories in individuals with or at risk for knee osteoarthritis (OA). METHODS The Osteoarthritis Initiative is a prospective cohort study of individuals with or at high risk for knee OA. Confidence in the knees was assessed within the Knee Injury and Osteoarthritis Outcome Score instrument querying how much the individual is troubled by lack of confidence in his/her knee(s), rated as not-at-all (score = 0), mildly (score = 1), moderately (score = 2), severely (score = 3), and extremely (score = 4) troubled, reported annually from baseline to 96 months. Lack of knee confidence was defined as a score of ≥2. We used latent class models to identify subgroups that share similar underlying knee confidence trajectories over an 8-year period and multivariable multinomial logistic regression models to examine baseline factors associated with poor trajectories. RESULTS Among 4,515 participants (mean ± SD age 61.2 ± 9.2 years, mean ± SD BMI 28.6 ± 4.8 kg/m2 ; 2,640 [58.5%] women), 4 distinct knee confidence trajectories were identified: persistently good (65.6%); declining (9.1%); poor, improving (13.9%); and persistently poor (11.4%). Baseline predictors associated with persistently poor confidence (reference: persistently good) were younger age, male sex, higher body mass index (BMI), depressive symptoms, more advanced radiographic disease, worse knee pain, weaker knee extensors, history of knee injury and surgery, and reported hip and/or ankle pain. CONCLUSION Findings suggest the dynamic nature of self-reported knee confidence and that addressing modifiable factors (e.g., BMI, knee strength, depressive symptoms, and lower extremity pain) may improve its long-term course.

Abstract
OBJECTIVE Reduced knee confidence is common in people with knee osteoarthritis (OA) and is likely to influence how people with knee OA engage with movement and activities. However, there is conflicting evidence surrounding the association between confidence and function. This may be because knee confidence has been assessed via a single questionnaire item that was not developed for people with knee OA and thus may not provide an accurate or comprehensive assessment of confidence in this population. A better understanding of knee confidence could inform a more thorough assessment of the construct both in clinical and research contexts. Therefore, the aim of this study was to explore the meaning of knee confidence from the perspective of people with knee OA. METHODS Fifty-one people with a clinical diagnosis of knee OA took part in a one-to-one semistructured interview. Interviews explored how each participant conceptualized knee confidence. Reflexive thematic analysis was selected as a flexible approach for identifying patterns of meaning across cases through a combination of data-driven and theory-informed coding of the transcribed data. RESULTS People with knee OA conceptualized confidence with reference to 1 or more of 4 themes: (1) symptoms, (2) functional ability, (3) the internal structure of the knee, and (4) knowledge about knee OA and its management. Each conceptualization of confidence was associated with present and future concerns. CONCLUSION Because people with knee OA conceptualize knee confidence in different ways, a single-item measure is unlikely to capture all of the aspects of this construct in this population. This may explain the conflicting evidence around the association between reduced knee confidence and function in people with knee OA. IMPACT This study showed that a multi-item measure is needed to measure knee confidence in people with knee OA. Clinicians and researchers need to understand what knee confidence means to people with knee OA, because it is likely to influence how these individuals engage with movement and activities. Understanding this relationship can enable more targeted education and functional rehabilitation for people with knee OA.

Abstract
This study aims to identify the relationship between knee functional status and Health-Related QoL (HRQoL) in mild to moderate knee osteoarthritis (OA) patients and to ascertain which subdomain of knee functional status best predicts good HRQoL. A cross-sectional study was conducted in an orthopaedic clinic of a tertiary hospital in Malaysia. Patients aged 40–75 years old with mild–moderate primary knee OA were recruited. The Knee Injury and Osteoarthritis Outcome Score (KOOS) and SF-36 questionnaires were used to measure knee functional status and HRQoL, respectively. Subdomains of KOOS include “function in daily living”, “function in recreational activities”, “pain”, “symptom”, and “knee-specific quality of life”. Subdomains for SF-36 are Physical Component Summary (PCS) and Mental Component Summary (MCS). Overall, 290 patients fulfilled the inclusion criteria of the study, with a mean age of 66.8 years old (±7.06). Majority were female (57.6%) and Malay (79.7%). The relationships between all KOOS and HRQoL subdomains were significant. “Pain” contributed most towards better physical HRQoL ((PCS) Adj. B (95% CI); 0.063 (0.044, 0.169)), while “function in daily living” contributed most towards better mental HRQoL ((MCS) Adj. B (95% CI); 0.624 (0.478, 0.769)). Thus, better HRQoL was related to better pain control and improved “function in daily living” in these patients.

Abstract
INTRODUCTION Frontal plane knee control is essential to athletic knee injury prevention. AIM To evaluate knee valgus frontal plane projection angle (FPPA), knee safety, and sports movement capability confidence during single leg triple hop for distance (SLTHD) under knee sleeve, distal thigh compression garment (DTCG), and no device (control) conditions. METHODS A single-session, experimental study was performed using a within-subject design, and randomized device order. Two-dimensional FPPA measurements were collected during the final SLTHD landing of 18 healthy female college athletes for each condition. Sports movement capability and knee safety confidence were measured using 10-cm visual analog scale questions. One-way ANOVA assessed group differences, and Pearson correlations delineated FPPA, knee safety and sports movement capability confidence relationships (p < 0.05). RESULTS The DTCG group had less valgus FPPA than the control group. The knee sleeve group had greater knee safety confidence than the control group. The DTCG (r = 0.48) had a moderate positive relationship between mean SLTHD and knee safety confidence. The DTCG group also had a moderate relationship between maximum SLTHD and knee safety confidence (r = 0.52). The DTCG and knee sleeve groups displayed moderate direct, and moderate inverse relationships between FPPA and sports movement capability confidence (r = 0.48 and r = -0.44, respectively). CONCLUSION Reduced FPPA and relationships between maximum SLTHD magnitude and knee safety confidence, and between FPPA magnitude and sports movement capability confidence suggests that the DTCG may enhance pelvic deltoid kinesthetic acuity and dynamic knee stability through iliotibial tract compression. CLINICAL RELEVANCE The DTCG was superior to the standard knee sleeve or control conditions for displaying characteristics that might better prevent knee injury, while still enabling effective sports movement capability.

Abstract
OBJECTIVE To determine prevalence, severity, and clinical correlates of pain flares in response to a repeated sit-to-stand activity. DESIGN Cross-sectional. METHODS The analyses included 11 013 patients with knee osteoarthritis (OA) and 3889 patients with hip OA who completed a 30-second chair-stand test before starting the Good Life with osteoArthritis in Denmark treatment program. Prevalence and severity of pain flares were evaluated by change in self-reported joint pain intensity on an 11-point numeric rating scale after the test. Correlates with pain flares (an increase on the numeric rating scale of 2 points or greater) were assessed using regression analyses. RESULTS One out of 3 patients with knee OA and 1 out of 5 patients with hip OA experienced pain flares (numeric rating scale of 2 or greater). Low knee/hip confidence, 3 or more painful body sites, fewer than 12 chair stands in 30 seconds, and body mass index of 30 kg/m2 or greater were associated with pain flares in response to the 30-second chair-stand test in patients with knee and hip OA. Low self-efficacy and joint stiffness were associated with pain flares in patients with knee OA. Using pain medication was associated with pain flares in patients with hip OA. CONCLUSION Pain flares in response to a repeated sit-to-stand activity were common in patients with knee and hip OA. The clinical correlates associated with pain flares included joint confidence, functional performance, and body mass index, and are potentially modifiable with patient education, exercise therapy, and weight loss, respectively.

Abstract
Objectives Wearing a soft knee brace has been shown to reduce self-reported knee instability in persons with knee OA. There is a need to assess whether a soft knee brace has a beneficial effect on objectively assessed dynamic knee instability as well. The aims of the study were to evaluate the effect of a soft knee brace on objectively assessed dynamic knee instability and to assess the difference in effect between a non-tight and a tight soft knee brace in persons with knee OA. Methods Thirty-eight persons with knee OA and self-reported knee instability participated in a laboratory study. A within-subject design was used comparing no brace vs brace and comparing a non-tight vs a tight brace. The primary outcome measure was dynamic knee instability, expressed by the perturbation response (PR). The PR reflects deviation in the mean knee varus-valgus angle during level walking after a controlled mechanical perturbation. Linear mixed-effect model analysis was used to evaluate the effect of a brace on dynamic knee instability. Results Wearing a brace significantly reduced the PR compared with not wearing a brace (B = -0.16, P = 0.01). There was no difference between a non-tight and a tight brace (B = -0.03, P = 0.60). Conclusion This study is the first to report that wearing a soft knee brace reduces objectively assessed dynamic knee instability in persons with knee OA. Wearing a soft brace results in an objective improvement of knee instability beyond subjectively reported improvement. Trial registration Nederlands Trial register (trialregister.nl) NTR6363.
