A cross-sectional study of associations between kinesiophobia, pain, disability, and quality of life in patients with chronic low back pain

Evaluation of maladaptive beliefs in patients with migraine: measurement properties for three versions (TSK-11, TSK-13, and TSK-17) of the Tampa Scale for Kinesiophobia

BACKGROUND

The Tampa Scale for Kinesiophobia (TSK) is one of the most frequently employed instruments for assessing maladaptive beliefs about pain, injury, and movement in patients with chronic musculoskeletal pain. However, the measurement properties of this tool have so far not been tested for individuals with migraine.

OBJECTIVE

To evaluate the structural, construct, and criterion validity, and the internal consistency for three versions (TSK-11, TSK-13, and TSK-17) of the TSK for patients with migraine.

METHODS

A total of 113 individuals aged between 18 and 55 years old with migraine diagnosis were included. All participants completed the TSK with 17 items, the Fear-Avoidance Beliefs Questionnaire, the Headache Impact Test, and the Pain Catastrophizing Scale questionnaires. Confirmatory factor analysis was used to assess the structural validity of the TSK, and Cronbach's α was used to assess internal consistency. For construct and criterion validity, the Spearman's correlation was calculated.

RESULTS

The TSK structure with one factor and the 17, 13, or 11 items versions were suitable, with suitable values in all fit indices related to structural validity. The three versions showed acceptable internal consistency (α = 0.75). All TSK versions showed moderate positive correlation with the other questionnaires (rho range= 0.31-0.63), confirming most of the predefined hypothesis for the construct validity. Also, the criterion validity of the 13-item and 11-item versions was confirmed (rho=0.95 and rho=0.94, respectively).

CONCLUSION

All versions of the TSK demonstrated good measurement properties in the assessment of maladaptive beliefs about pain, injury, and movement in individuals with migraine.

The mediating role of cardiac patients' perception of nursing care on the relationship between kinesiophobia, anxiety and depression in rural hospitals: a cross-sectional study

BACKGROUND

Kinesiophobia could act as a significant barrier against physical activity following cardiac procedures worsening cardiovascular health problems and potentially leading to conditions like hospital-acquired anxiety and depression among patients with cardiovascular disease (CVD). Nurses are the vanguard health care team who can aid patients in taking proactive steps to overcome fear of movement following cardiac procedures.

AIM

The overarching aim is to investigate the relationship between kinesiophobia, anxiety and depression, and patients' perception of nursing care.

METHOD

A descriptive correlational research design in two rural hospitals, conducted at cardiac intensive care units of Kafr Eldawar Hospital and Damanhur Medical National Institute. Data were collected from 265 nurses, using the following patient-reported outcome measures, the Tampa Scale for Kinesiophobia (TSK), the Hospital Anxiety and Depression Scale (HADS), the Person-Centered Critical Care Nursing Questionnaire (PCCNP) and the patients' demographic and clinical profile.

RESULT

A significant negative correlation was found between HADS and PCCNP (r: -0.510, p < 0.001) however, Kinesiophobia was significantly and positively correlated (r: 0.271, p < 0.001). A direct effect of PCCNP in the presence of the mediator was found to be not statistically significant (-0.015, CR = 0.302, p = 0.763). Nonetheless, PCCNP indirectly affects kinesiophobia through HADS (p=-0.099).

IMPLICATION FOR NURSING PRACTICE

Customizing individualized cardiac rehabilitation (CR) programs based on the emotional experience of cardiac patients will be conducive to rehabilitation and prognosis for patients, thereby lessening the physical burden and improving their quality of life.

Exploring Interactions Between Sex, Pain Characteristics, Disability, and Quality of Life in People With Chronic Spinal Pain: A Structural Equation Model

In people with nonspecific chronic spinal pain (nCSP), disability and quality of life are associated with clinical, cognitive, psychophysical, and demographic variables. However, evidence regarding the interactions between these variables is only limited to this population. Therefore, this study aims to explore path models explaining the multivariate contributions of such variables to disability and quality of life in people with nCSP. This secondary analysis uses baseline data from a randomized controlled trial including 120 participants with nCSP. Structural equation modeling was used to explore path models for the Pain Disability Index (PDI), the Short Form 36-item physical (SF-36 PC), and mental (SF-36 MC) component scores. All models included sex, pain catastrophizing, kinesiophobia, hypervigilance, and pain intensity. Additionally, the PDI and SF-36 PC models included pressure pain thresholds (PPTs) at the dominant pain site (ie, neck or low back). Significant associations were found between sex, pain cognitions, pain intensity, and PPTs. Only pain catastrophizing significantly directly influenced the PDI (P ≤ .001) and SF-36 MC (P = .014), while the direct effects on the SF-36 PC from kinesiophobia (P = .008) and pain intensity (P = .006) were also significant. However, only the combined effect of all pain cognitions on the SF-36 PC was mediated by pain intensity (P = .019). Our findings indicate that patients' pain-related cognitions have an adverse effect on their physical health-related quality of life via a negative influence on their pain intensity in people with nCSP. PERSPECTIVE: This secondary analysis details a network analysis confirming significant interactions between sex, pain cognitions, pain intensity, and PPTs in relation to disability and health-related quality of life in people with chronic spinal pain. Moreover, its findings establish the importance of pain cognitions and pain intensity for these outcomes. TRIALS REGISTRATION: Clinicaltrials.gov (NCT02098005).

The relationship between kinesiophobia severity and clinical parameters in patients with mechanical low back pain

BACKGROUND

Low back pain is an important widespread health problem that can occur at any age, causing serious socioeconomic losses.

OBJECTIVE

The objective of this study is to investigate the relationship between kinesiophobia severity and pain severity, depression, and quality of life in patients with mechanical low back pain.

METHODS

The study sample consisted of 155 patients, of whom 72 were female and 83 were male, aged between 18 and 75 years with mechanical low back pain. Quality of life was assessed with the 36-Item Short Form Health Survey (SF-36), pain intensity with the Visual Analogue Scale (VAS), kinesiophobia with the Tampa Kinesiophobia Scale (TKS), and depression with the Beck Depression Inventory (BDI). Patients were divided into the low (TKS ⩽ 37) and high kinesiophobia (TKS > 37) groups according to the scores they obtained from TKS.

RESULTS

VAS-pain severity and BDI scores were significantly higher in the high kinesiophobia group than in the low kinesiophobia group (p< 0.001). On the other hand, the SF-36 subscale scores were significantly higher in the low kinesiophobia group than in the high kinesiophobia group (p< 0.001). The TKS scores were moderately correlated with VAS-pain severity (r= 0.470; p< 0.001) and BDI scores (r= 0.584; p< 0.001) in the positive direction, and strongly correlated with all sub-parameters of quality of life in the negative direction (p< 0.001).

CONCLUSION

The results indicated that the severity of kinesiophobia in patients with non-inflammatory low back pain is associated with pain severity, depression, and poor quality of life.

Kinesiophobia and its associated factors in patients with coronary heart disease: a cross-sectional study based on latent feature analysis

OBJECTIVES

The aim of this study was to explore the current situation of kinesiophobia in patients with coronary heart disease, classify it based on potential profile analysis and explore the relevant factors of kinesiophobia in different categories of patients with coronary heart disease.

DESIGN

Cross-sectional study.

SETTING

Patients with coronary heart disease in China.

PARTICIPANTS

Adult (aged >18 years) patients with coronary heart disease in China; 252 participants in this study answered the questionnaire.

PRIMARY AND SECONDARY OUTCOME MEASURES

The study investigated the scores of Tampa Scale for Kinesiophobia Heart, and collected information on the patient's age, gender, monthly household income, education level, place of residence, marital status, occupational status, hypertension, diabetes, heart failure and body mass index (BMI).

RESULTS

Kinesiophobia in patients with coronary heart disease can be divided into low fear type (C1), intermediate fear type (C2) and high fear type (C3). Elderly patients were classified as type C3. Women and patients with a normal BMI were classified as type C1; patients with a normal BMI and patients with an overweight BMI were classified as type C2.

CONCLUSION

Kinesiophobia of patients with coronary heart disease can be divided into three categories, and intervention measures are implemented according to their different demographic characteristics to reduce kinesiophobia of patients and promote the participation of patients in exercise rehabilitation.

Group differences and associations between patient-reported outcomes and physical characteristics in chronic low back pain patients and healthy controls

BACKGROUND

Patients with chronic low back pain can exhibit altered slower gait, poor balance, and lower strength/power, and psychological dysfunctions such as pain catastrophizing and fear of movement. Few studies have investigated the relationships between physical and psychological dysfunctions. This study examined associations between patient-reported outcomes (pain interference, physical function, central sensitization, and kinesiophobia) and physical characteristics (gait, balance, and trunk sensorimotor characteristics).

METHODS

Laboratory testing included a 4-m walk, balance, and trunk sensorimotor testing with 18 patients and 15 controls. Gait and balance were collected with inertial measurement units. Isokinetic dynamometry measured trunk sensorimotor characteristics. Patient-reported outcomes included PROMIS Pain Interference / Physical Function, Central Sensitization Inventory, and Tampa Scale of Kinesiophobia. Independent t-tests or Mann-Whitney U tests were used to compare between groups. Additionally, Spearman's rank correlation coefficient (r_s) established associations between physical and psychological domains, and Fisher z-tests compared correlation coefficient values between groups (significance P < 0.05).

FINDINGS

The patient group had worse tandem balance and all patient-reported outcomes (P < 0.05) while no group differences were observed in gait and trunk sensorimotor characteristics. There were significant correlations between worse central sensitization and poor tandem balance (r_s = 0.446-0.619, P < 0.05) and lower peak force and rate of force development (r_s = -0.429-0.702, P < 0.05).

INTERPRETATION

Observed group differences in tandem balance agree with previous studies, indicating impaired proprioception. The current findings provide preliminary evidence that balance and trunk sensorimotor characteristics were significantly associated with patient-reported outcomes in patients. Early and period screening could help clinicians further categorize patients and develop objective treatment plans.

Associations between gait performance and pain intensity, psychosocial factors, executive functions as well as prefrontal cortex activity in chronic low back pain patients: A cross-sectional fNIRS study

Introduction

Activities of daily living, such as walking, are impaired in chronic low back pain (CLBP) patients compared to healthy individuals. Thereby, pain intensity, psychosocial factors, cognitive functioning and prefrontal cortex (PFC) activity during walking might be related to gait performance during single and dual task walking (STW, DTW). However, to the best of our knowledge, these associations have not yet been explored in a large sample of CLBP patients.

Method

Gait kinematics (inertial measurement units) and PFC activity (functional near-infrared spectroscopy) during STW and DTW were measured in 108 CLBP patients (79 females, 29 males). Additionally, pain intensity, kinesiophobia, pain coping strategies, depression and executive functioning were quantified and correlation coefficients were calculated to determine the associations between parameters.

Results

The gait parameters showed small correlations with acute pain intensity, pain coping strategies and depression. Stride length and velocity during STW and DTW were (slightly to moderately) positively correlated with executive function test performance. Specific small to moderate correlations were found between the gait parameters and dorsolateral PFC activity during STW and DTW.

Conclusion

Patients with higher acute pain intensity and better coping skills demonstrated slower and less variable gait, which might reflect a pain minimization strategy. Psychosocial factors seem to play no or only a minor role, while good executive functions might be a prerequisite for a better gait performance in CLBP patients. The specific associations between gait parameters and PFC activity during walking indicate that the availability and utilization of brain resources are crucial for a good gait performance.

The Mediation Effect of Pain on the Relationship between Kinesiophobia and Lumbar Joint Position Sense in Chronic Low Back Pain Individuals: A Cross-Sectional Study

(1) Background: Fear of movement (kinesiophobia) and impaired lumbar joint position sense (LJPS) play a vital role in developing and maintaining non-specific chronic low back pain (CLBP). However, how kinesiophobia impacts LJPS is still being determined. The aims of this study are to (1) assess the correlation between kinesiophobia and LJPS in individuals with chronic low back pain; (2) compare LJPS between individuals with CLBP and those who are asymptomatic; and (3) evaluate if pain can mediate the relationship between kinesiophobia and LJPS in CLBP individuals. (2) Methods: Eighty-three individuals (mean age = 48.9 ± 7.5 years) with a diagnosis of CLBP and 95 asymptomatic individuals (mean age = 49.4 ± 7.0 years) were recruited into this cross-sectional study. Fear of movement in CLBP individuals was assessed using the Tampa Scale for Kinesiophobia (TSK). LJPS was determined using the active target repositioning technique using a dual-digital inclinometer. LJPS was evaluated in lumbar flexion, extension, and side-bending left and right directions, and the repositioning accuracy was determined in degrees using a dual digital inclinometer. (3) Results: Kinesiophobia showed a significant (p < 0.001) moderate positive correlation with LJPS (flexion: r = 0.51, extension: r = 0.41, side-bending left: r = 0.37 and side-bending right: r = 0.34). LJPS errors were larger in CLBP individuals compared to asymptomatic individuals (p < 0.05). Mediation analyses showed that pain significantly mediated the relationship between kinesiophobia and LJPS (p < 0.05) in CLBP individuals. (4) Conclusions: Kinesiophobia and LJPS were positively associated. LJPS is impaired in CLBP individuals compared to asymptomatic individuals. Pain may mediate adverse effects on LJPS. These factors must be taken into account when assessing and developing treatment plans for those with CLBP.

Biopsychosocial Approach in Identifying Risk Factors of Kinesiophobia in Persons with Subacromial Pain Syndrome and Developing a Clinical Prediction Tool

Introduction

Although the negative effects of kinesiophobia on functional status in subacromial pain syndrome (SAPS) patients are clearly demonstrated, no study examines the risk factors of kinesiophobia in individuals with SAPS from a biopsychosocial perspective. The present study aims to determine the risk factors of kinesiophobia in individuals with SAPS using a biopsychosocial approach. This study also aims to explore the compounding effects of multiple associative risk factors by developing a clinical prediction tool to identify SAPS patients at higher risk for kinesiophobia.

Materials and methods

This cross-sectional study included 549 patients who were diagnosed with SAPS. The Tampa-Scale of Kinesiophobia (TSK) was used to assess kinesiophobia. Visual analog scale (VAS), The Shoulder Pain and Disability Index (SPADI), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, the presence of metabolic syndrome, using any non-steroidal anti-inflammatory drugs, Pain Catastrophizing Scale (PCS), Illness Perception Questionnaire-revised (IPQ-R), Hospital Anxiety and Depression Scale (HADS), behavioral pattern of the patient, sociodemographic characteristics, and treatment expectancy were outcome measures.

Results

Thirteen significant risk factors of having kinesiophobia were: VASat rest (≥ 5.2), VASduring activity (≥ 7.1), DASH (≥ 72.1), presence of metabolic syndrome, PCShelplessness (≥ 16.1), IPQ-Rpersonal control (≤ 17.1), IPQ-Rtreatment control (≤ 16.3), HADSdepression (≥ 7.9), avoidance behavior type, being female, educational level (≤ high school), average hours of sleep (≤ 6.8), and treatment expectancy (≤ 6.6). The presence of seven or more risk factors increased the probability of having high level of kinesiophobia from 34.3 to 51%.

Conclusions

It seems necessary to address these factors, increase awareness of health practitioners and individuals.

Investigation of Factors Associated With Pain Intensity in Office Workers With Non-Specific Low Back Pain

BACKGROUND

Low back pain is an important health problem causing serious physical, psychological, and economic losses in developed and developing countries.

AIM

The aim of this study is to investigate comprehensively the factors related to the intensity of pain in office workers with non-specific low back pain (NSLBP).

METHODS

The study included 71 university office workers with NSLBP, aged 21-55 years. In addition to evaluating the sociodemographic and clinical characteristics of office workers with NSLBP, visual analog scale (VAS), Short-Form 36 (SF-36), Minnesota Satisfaction Questionnaire (MSQ), Oswestry Disability Index (ODI), Tampa Kinesiophobia Scale (TKS), Beck Depression Inventory (BDI), and Timed Up and Go (TUG) outcome measurements were applied.

RESULTS

There was a statistically significant association between the intensity of pain and TUG test (p = .000), job satisfaction (p = .015), percentages of disability (p = .000), quality of life (role difficulty due to physical limitation, p = .010; pain, p = .000; social the function, p = .044), and depression (p = .004).

CONCLUSIONS

While the functional performance, job satisfaction level, and quality of life in office workers with NSLBP with severe-intensity pain were lower, level of disability, depression were higher in office workers with NSLBP with mild-to-moderate-intensity pain.

Non-invasive brain stimulation and pain neuroscience education in the cognitive-affective treatment of chronic low back pain: Evidence and future directions

Chronic low back pain (CLBP) is among the leading causes of disability worldwide. Beyond the physical and functional limitations, people's beliefs, cognitions, and perceptions of their pain can negatively influence their prognosis. Altered cognitive and affective behaviors, such as pain catastrophizing and kinesiophobia, are correlated with changes in the brain and share a dynamic and bidirectional relationship. Similarly, in the presence of persistent pain, attentional control mechanisms, which serve to organize relevant task information are impaired. These deficits demonstrate that pain may be a predominant focus of attentional resources, leaving limited reserve for other cognitively demanding tasks. Cognitive dysfunction may limit one's capacity to evaluate, interpret, and revise the maladaptive thoughts and behaviors associated with catastrophizing and fear. As such, interventions targeting the brain and resultant behaviors are compelling. Pain neuroscience education (PNE), a cognitive intervention used to reconceptualize a person's pain experiences, has been shown to reduce the effects of pain catastrophizing and kinesiophobia. However, cognitive deficits associated with chronic pain may impact the efficacy of such interventions. Non-invasive brain stimulation (NIBS), such as transcranial direct current stimulation (tDCS) or repetitive transcranial magnetic stimulation (rTMS) has been shown to be effective in the treatment of anxiety, depression, and pain. In addition, as with the treatment of most physical and psychological diagnoses, an active multimodal approach is considered to be optimal. Therefore, combining the neuromodulatory effects of NIBS with a cognitive intervention such as PNE could be promising. This review highlights the cognitive-affective deficits associated with CLBP while focusing on current evidence for cognition-based therapies and NIBS.

Status and influencing factors of patients with kinesiophobia after insertion of peripherally inserted central catheter: A cross-sectional study

This study aimed to investigate the current status and influencing factors of kinesiophobia in patients after insertion of peripherally inserted central catheter (PICC). A total of 240 patients with PICC were included. Their postinsertion status and influencing factors were investigated using the general information questionnaire, Tampa Scale of Kinesiophobia (TSK), Medical Coping Modes Questionnaire, Numerical Rating Scale, and Self-rating Anxiety Scale. The mean TSK score was 36.49 ± 4.19 points, and 89 patients (37.08%) had kinesiophobia. Multiple linear regression analysis showed that factors such as education level, age, monthly income level, catheterization history, face, pain level, anxiety, and number of needle insertions influenced postoperative kinesiophobia in patients with PICC (P < .05). The total variation in the TSK score was 71.8%. The incidence of kinesiophobia was relatively high after PICC insertion. The medical staff needs to undertake targeted intervention measures to help minimize kinesiophobia after PICC insertion, allowing patients to perform scientifically correct functional exercises and attain physical recovery.

Kinesiophobia and associated factors among patients with chronic non-specific low back pain

PURPOSE

This study determined the association between kinesiophobia and age, body mass index, highest educational status, self-efficacy, pain intensity, and disability in chronic non-specific low back pain (CNSLBP) patients. Predictors of kinesiophobia were also assessed.

METHODS

This cross-sectional design utilised 224 CNSLBP patients in tertiary hospitals in Nigeria. The Tampa Scale of Kinesiophobia, Oswestry Disability Index, Pain Self-Efficacy Questionnaire, and Numerical Pain Rating Scale were used to assess kinesiophobia, disability, self-efficacy, and pain intensity respectively. Spearman's correlation and multiple regression analysis determined the association between the variables of interest and the predictors of kinesiophobia, respectively.

RESULTS

Most of the participants reported a high level of kinesiophobia (92%), low level of self-efficacy (68.8%), moderate pain intensity (58.0%), and moderate disability (57.1%). A significant positive weak correlation was observed between kinesiophobia and pain intensity (r = 0.138, p = 0.040). Gender, self-efficacy, pain intensity, and disability significantly predicted the extent of kinesiophobia (p < 0.05).

CONCLUSION

The increased levels of kinesiophobia are a cause for concern and highlight the need for kinesiophobia and related factors to be closely monitored and incorporated into preventive and curative rehabilitation programmes for CNSLBP patients to minimise the negative impact on rehabilitation outcomes.Implications for RehabilitationPatients with chronic non-specific low back pain (CNSLBP) have high levels of kinesiophobia, which could predispose them to avoidance behaviours, physical inactivity, and deterioration of health, all of which, if not addressed, may result in poor rehabilitation outcomes, setting off a viscious cycle.Regular kinesiophobia assessments could indicate areas of rehabilitation concern, allowing health care providers to better target rehabilitation programs and improve rehabilitation outcomes.Pain severity, self-efficacy, and disability should be frequently assessed and included when planning rehabilitation programs, to reduce the detrimental impact on kinesiophobia.In patients with CNSLBP, graded exposure therapy to movement is necessary to prevent and reduce kinesiophobia, thereby increasing compliance during rehabilitation programs.

Sex Differences in the Mediating Effect of Kinesiophobia on Chronic Pain, Dysesthesia, and Health-Related Quality of Life in Japanese Individuals Aged 65 Years Old and Older Treated with Surgery for Lumbar Spinal Stenosis

Purpose

This study aimed to determine whether kinesiophobia mediates the relationship between low back pain (LBP), leg pain (LP), and leg dysesthesia (LD) and health-related quality of life (HRQOL) among Japanese individuals aged 65 years old and older treated with surgery for lumbar spinal stenosis (LSS).

Patients and Methods

Data collection for this study took place between October 2019 and August 2020 at two Japanese medical facilities. Eligibility criteria for participants in this study were individuals aged 65 years or older and those who had undergone surgery for LSS at least more than one year ago. A self-administered questionnaire assessed the intensity of LBP, LP, and LD (numerical rating scale: NRS), HRQOL (EuroQol-5 Dimension-5 Levels: EQ-5D-5L), and kinesiophobia (Tampa Scale for Kinesiophobia-17 items: TSK-17). Mediation analysis using sex as a control variable was conducted.

Results

Complete responses were obtained from 238 of 431 individuals (73.1 ± 5.1 years; 135 males and 103 females). The mediating effect of NRS scores for LBP, LP, and LD to EQ-5D-5L index on TSK-17 score was significant, respectively (LBP: -0.007 [95% confidence interval -0.012, -0.004], p = 0.000; LP and LD: -0.007 [-0.011, -0.004], p = 0.000). The strength of the association between NRS scores and EQ-5D-5L index decreased when the mediating effect of TSK-17 score (LBP: β = -0.698 [-0.792, -0.603], p = 0.000 to β = -0.616 [-0.707, -0.524], p = 0.000; LP: β = -0.629 [-0.729, -0.529], p = 0.000 to β = -0.539 [-0.638, -0.440], p = 0.000; LD: β = -0.568 [-0.675, -0.460], p = 0.000 to β = -0.482 [-0.586, -0.378], p = 0.000). The mediating effect of TSK score was greater in females than males.

Conclusion

Kinophobia partially mediated the relationship between LBP, LP and LD, and HRQOL in Japanese aged 65 years and older after lumbar surgery. The mediating effect differed by sex.

Fear-Avoidance Beliefs, Kinesiophobia, and Disability Risk Among Indians with Spine Pain

PURPOSE

To determine the burden of fear-avoidance beliefs (FAB), kinesiophobia, and risk of persistent disability among Indians with spine pain.

METHODS

Demographic and clinical data collected from 139 patients who attended a spine rehabilitation clinic for assessment and treatment of their spine pain were analyzed. Fear-avoidance beliefs, kinesiophobia, and risk of persistent disability were measured using the Fear-avoidance Beliefs Questionnaire (FABQ), Tampa Scale for Kinesiophobia (TSK), and the STarT Back Tool (SBT). A multivariate analysis was performed to determine the effect of pain, disability, age, gender, BMI, lifestyle, pain duration, and pain location on FAB, TSK, and SBT scores.

RESULTS

A majority of patients had medium to high-risk FAB-physical activities (FAB-P) (50.5%) and SBT (54%) scores. The percentage of patients with medium or high-risk FAB-P (p = 0.03), FAB-work (FAB-W) (p = 0.03), and SBT (p = 0.03) scores were significantly higher in patients with pain score > 7, and the percentage of patients with medium or high-risk with FAB-P (p < 0.0001), TSK (p = 0.0003), and SBT (p < 0.0001) scores were significantly higher in patients with severe, crippled or bed-ridden disability. Disability was the only significant predictor for FAB-W, FAB-P, and SBT scores.

CONCLUSION

The prevalence of fear-avoidance beliefs and risk of persistent disability was significant among Indians and should be taken into account while planning treatment for their spine pain.

Negative Psychological Factors' Influence on Delayed Onset Muscle Soreness Intensity, Reduced Cervical Function and Daily Activities in Healthy Participants

We examined the influence of negative psychological factors (catastrophizing, distress and kinesiophobia) on delayed onset muscle soreness (DOMS) intensity, cervical function (strength and range of motion) and on daily activities (ADL), and the suitability of an exercise protocol designed to induce DOMS within the cervical region. Psychological factors and cervical function were assessed in 86 healthy participants at baseline before applying a DOMS provocation protocol in the cervical flexor muscles. After 24hour, cervical function was reassessed. In addition, at 24hour and 48hour, the intensity of DOMS and its impact on ADL were assessed using the visual analog scale (VAS). The protocol was effective given that it generated low-moderate intensity DOMS (VAS≈30 -40mm) and a statistically significant reduction in cervical strength and range of motion. Psychological distress (anxiety and depression), but not kinesiophobia and catastrophism, predicted a loss of cervical strength (explained 43% of the variance) and range of motion (explained 22% of the variance) after induction of DOMS. In addition, participants' anxiety level predicted DOMS intensity at 24hour (explained 19% of the variance). PERSPECTIVE: The present findings highlight the relevance of evaluating psychological distress as a preventive/therapeutic measure, given that high levels of distress could lead to more intense and disabling pain in acute injuries, and all these aspects are considered risk factors for the chronification of symptoms.

Efficacy of duloxetine in patients with knee osteoarthritis or chronic low back pain with early pain reduction: An exploratory post-hoc analysis of Japanese phase 3, 1-year extension studies

BACKGROUND

Two previous phase 3, double-blind, randomized, placebo-controlled trials showed that duloxetine 60 mg/day for 14 weeks significantly improved pain and quality of life in Japanese patients with knee osteoarthritis or chronic low back pain. In their open-label extension studies, these improvements were maintained for ≥48 weeks. This post-hoc analysis assessed the relationship between initial response to duloxetine and long-term pain reduction and quality of life in patients with knee osteoarthritis or chronic low back pain.

METHODS

Patients (knee osteoarthritis: N = 43; chronic low back pain: N = 41) were subdivided based on extent of pain reduction from baseline to Week 4 of duloxetine (≥30%, 10-30%, or <10% reduction in Brief Pain Inventory-Severity average pain score). Outcome measures were changes from baseline for Brief Pain Inventory-Severity and Brief Pain Inventory-Interference at regular intervals up to Week 65.

RESULTS

Mean change from baseline in Brief Pain Inventory-Severity was greater in patients with ≥30% early pain reduction than in patients with <10% early pain reduction through Week 27 for both conditions, and also Weeks 47-65 for back pain. Compared with the <10% early pain reduction group, mean change from baseline in the average of seven Brief Pain Inventory-Interference domain scores was greater in the ≥30% or 10-30% early pain reduction groups for knee osteoarthritis (except Weeks 63-65), and in the ≥30% early pain reduction group for chronic low back pain through Week 19.

CONCLUSIONS

These results suggest that patients with knee osteoarthritis who respond well to duloxetine in the first month might experience sustained, long-term pain relief with generally greater quality-of-life improvement than patients with poor initial response. Patients with chronic low back pain who had strong initial response may experience a greater long-term pain relief, but not greater quality-of-life improvement, than patients with poor initial response.

Determinants of quality of life in individuals with chronic low back pain: a systematic review

OBJECTIVE

Chronic low back pain (CLBP) is a prominent medical condition that can affect an individual at some point in their life time which could lead to poor quality of life (QOL). Low back pain has affected approximately 577 million individuals globally by 2017. The aim of the current systematic review is to synthesise the existing evidence on the factors influencing the QOL in individuals with CLBP and to identify strategies to improve their QOL.

METHOD

PubMed, ScienceDirect, PsychNet and Google Scholar were used to extract studies reporting quantitative relationships between QOL and its possible determinants in individuals having CLBP and the intervention strategies to improve QOL.

RESULTS

10,851 studies were initially identified and twenty-six studies which met the inclusion criteria were selected for the review. 21 studies reported relationship between QOL and potential determinants and five studies assessed the influence of interventions on QOL. Determinants were classified as kinesiophobia, fear avoidance belief, or pain belief; occupation-related factors; pain and disability; activity; personal factors including age, gender, employment status; and other psychological factors including anxiety, quality of sleep, and health locus of control. Intervention strategies including MBSR, Pilates method and Back School Programme improved QOL in individuals with CLBP.

CONCLUSION

Psychosocial factors as well as the physical status of the individual contributed to the QOL in individuals having CLBP.

Direct and Indirect Relationships Between Physical Activity, Fitness Level, Kinesiophobia, and Health-Related Quality of Life in Patients with Rheumatic and Musculoskeletal Diseases: A Network Analysis

Introduction

Using a network analysis, the present study investigated the extent to which physical activity (PA), objective fitness level, kinesiophobia, and health-related quality of life (HRQoL) interact in patients with rheumatic and musculoskeletal diseases. The objectives were twofold: 1) to clarify the direct and indirect relationships between these variables while controlling for the shared variance between them, and 2) to establish a potential ranking of influence among them.

Methods

This cross-sectional design study involved patients recruited from a rheumatology unit. One hundred and twenty patients completed self-reported measures of PA, the Tampa scale of kinesiophobia and the 36-item Short-Form Health Survey, and ninety-seven of those patients performed the six-minute walking test and the thirty-second sit-to-stand test. Network analyses were conducted using bootnet and qgraph packages.

Results

Weekly time spent on PA, as well as physical fitness measures, were directly linked to kinesiophobia and the HRQoL physical dimension, but indirectly linked to HRQoL mental dimension through the mediation of kinesiophobia. Specifically, weekly PA time had direct relationships to physical functioning, vitality, and role limitations due to physical and emotional problems. Fitness measures had direct relationships with physical functioning, bodily pain, and mental health. The analyses did not clearly highlight one variable as the most influential in the network.

Discussion

The study highlights the complexities of direct and indirect biopsychosocial relationships that are at the core of patients’ daily functioning. Measurement of PA, use of a longitudinal design, and interventions are discussed.

Association Between Self-Reported Kinesiophobia and Single-Leg Hop for Distance in Patients With ACL Reconstruction:A Systematic Review

CONTEXT

Psychological readiness is a significant factor in determining successful return to sport (RTS) and physical activities after anterior cruciate ligament (ACL) reconstruction. Knowing the influence of kinesiophobia on physical tests that are used to guide RTS, such as the single-leg hop for distance (SLHD), would contribute to advancing clinical practice.

OBJECTIVE

To investigate the association between kinesiophobia and SLHD performance in patients after ACL reconstruction.

DATA SOURCES

A comprehensive search strategy entailed surveying 6 databases for relevant articles published from January 2009 to March 2021.

STUDY SELECTION

Articles published in English that were a minimum of level 3 evidence describing kinesiophobia, as measured by the Tampa Scale for Kinesiophobia, and related to SLHD performance in patients after ACL reconstruction.

STUDY DESIGN

Systematic review.

LEVEL OF EVIDENCE

Level 3.

DATA EXTRACTION

Study characteristics, sample population demographics, instrument(s), or approach(s) used to assess kinesiophobia and SLHD performance, and corresponding results.

RESULTS

A total of 152 potential studies were identified, 106 studies underwent screening, 40 were reviewed in full, and 7 studies were included. Meta-analysis could not be performed because of differences in experimental design among studies and instances of missing outcome data. Currently, moderate evidence indicates patients with ACL reconstruction that exhibit less kinesiophobia perform better on the SLHD test.

CONCLUSION

The outcomes of this review propose that sports health practitioners consider the influence of kinesiophobia on SLHD performance as a criterion for RTS and physical activities in patients after ACL reconstruction. Higher quality studies are necessary to establish the extent of association between these variables.

Kinesiophobia and its correlations with pain, proprioception, and functional performance among individuals with chronic neck pain

Chronic neck pain (CNP) incidence in the general population is high and contributes to a significant health problem. Kinesiophobia (fear of pain to movement or re-injury) combined with emotions and physical variables may play a vital role in assessing and managing individuals with CNP. The study’s objectives are 1) to evaluate the relationship between kinesiophobia, neck pain intensity, proprioception, and functional performance; 2) to determine if kinesiophobia predicts pain intensity, proprioception, and functional performance among CNP individuals. Sixty-four participants with CNP (mean age 54.31 ± 9.41) were recruited for this cross-sectional study. The following outcome measures were evaluated: Kinesiophobia using the Tampa Scale of Kinesiophobia (TSK), neck pain intensity using the visual analog scale (VAS), cervical proprioceptive joint position errors (in flexion, extension, and rotation directions) using cervical range of motion (CROM) device and handgrip strength as a measure of functional performance using the Baseline® hydraulic hand dynamometer. Kinesiophobia showed a strong positive correlation with neck pain intensity (r = 0.81, p<0.001), a mild to a moderate positive correlation with proprioception joint position errors (JPE) in extension, rotation left and right directions (p<0.05), but no correlation in flexion direction (p = 0.127). Also, there was a moderate negative correlation with handgrip strength (r = -0.65, p<0.001). Regression analysis proved that kinesiophobia was a significant predictor of pain intensity, proprioception, and functional performance (p<0.05). This study infers that kinesiophobia in individuals with CNP predicts pain, proprioception, and functional performance. Kinesiophobia assessment should be considered in regular clinical practice to understand the barriers that can influence rehabilitation outcomes in CNP individuals.

Low Back Pain Assessment Based on Alpha Oscillation Changes in Spontaneous Electroencephalogram (EEG)

Objectively and accurately assessing pain in clinical settings is challenging. Previous studies showed that alpha oscillations of electroencephalogram data are correlated with subjective perceived pain. Based on this finding, this study is aimed at assessing chronic low back pain based on alpha oscillations. Multichannel electroencephalogram data were recorded from 27 subjects with chronic low back pain under the simple conditions of closing eyes or opening eyes. Spectral analyses were conducted to extract the alpha band responses, and the alpha powers were calculated for the two conditions, respectively. Normalized alpha power was calculated by subtracting the alpha power in the eyes-open condition from that in the eyes-closed condition. The correlation between the alpha power and the subjective pain intensity was evaluated in frontal, central, and posterior regions. The normalized alpha power in the central region was negatively correlated with the subjective pain intensity (R = -0.50, P = 0.01), with the strongest correlation occurring at the Cz electrode (R = -0.59, P = 0.04). The correlation analysis results demonstrated the possibility of using the differences of alpha spectral power between eyes-closed and eyes-open conditions as a measure for assessing chronic low back pain. The findings suggest that the normalized alpha power in the central region may be used as a measurable and quantitative indicator of chronic pain for clinical applications.

Influence of Stabilization Techniques Used in the Treatment of Low Back Pain on the Level of Kinesiophobia

The aim of this study was to try to compare the effectiveness of manual therapy techniques in combination with stabilization techniques: the so-called Australian method and the Neurac method in relation to pain sensations and the level of kinesiophobia. A total of 69 people were examined, divided into three groups of 23 people each. The Visual Analogue Scale was used to assess the antalgic effect, and the Kinesiophobia Causes Scale questionnaire was used to assess the level of kinesiophobia. Patients improved over four weeks, during which they were assessed three times. The evaluation of the desired parameters was also performed over a 24-week period to assess long-term performance. Stabilization techniques are an effective extension of manual therapy techniques in patients with low back pain. People in the groups additionally improved in terms of stabilization techniques, which are characterized by a lower level of kinesiophobia. Its lowest level was found in the group additionally improved with the Neurac method. In the long-term study, the level of kinesiophobia in this group was still maintained at a reduced level. The use of stabilization techniques involving patients in action may significantly affect the level of kinesiophobia, and thus have a much wider effect than just pain reduction.

Influence of Baseline Kinesiophobia Levels on Treatment Outcome in People With Chronic Spinal Pain

BACKGROUND

Pain neuroscience education (PNE) combined with cognition-targeted exercises is an effective treatment for people with chronic spinal pain (CSP). However, it is unclear why some patients benefit more from this treatment. We expect that patients with more pronounced maladaptive pain cognitions, such as kinesiophobia, might show poorer treatment responses.

OBJECTIVE

The objective of this study was to assess the influence of baseline kinesiophobia levels on the treatment outcomes of PNE combined with cognition-targeted exercises in people with CSP. This study was a secondary analysis of a multicenter, double-blind, randomized controlled trial.

METHODS

Outcome measures included a numeric rating scale for pain (NRS), the Pain Disability Index (PDI), quality of life (Medical Outcomes Study 36-Item Health Survey [SF-36]), Pain Catastrophizing Scale (PCS), and Pain Vigilance and Awareness Questionnaire (PVAQ). Regression models were built using treatment (PNE plus cognition-targeted exercises or neck/back school plus general exercises), baseline scores on the Tampa Scale for Kinesiophobia (TSK), and time (in months) as independent variables.

RESULTS

A significant 3-way interaction effect was found for the models of PDI, PCS, PVAQ, and the SF-36 mental domain, with estimates of -0.01, -0.01, -0.01, and 0.07, respectively. A significant effect of baseline TSK scores was found for the physical domain of the SF-36 (estimate = -3.16). For the NRS, no significant effect of baseline TSK scores was found.

CONCLUSION

Our findings indicate that PNE plus cognition-targeted exercises can successfully decrease the unfavorable influence of pretreatment kinesiophobia on disability, mental health, pain catastrophizing, and hypervigilance over time in people with CSP. Nevertheless, higher scores in pretreatment kinesiophobia might still be a key factor for the lack of improvement in pain catastrophizing and hypervigilance following treatment. Regardless of the followed treatment program, pretreatment kinesiophobia was also shown to significantly influence physical health in people with CSP.

IMPACT

This study provides novel insight into the unfavorable influence of kinesiophobia on treatment outcomes in people with CSP, and how PNE plus cognition-targeted exercises can limit this impact. Because this is one of the first studies to research possible predictors of this experimental treatment, its findings motivate further exploration of other possible influencing factors for treatment success of PNE plus cognition-targeted exercises.

LAY SUMMARY

People with chronic spinal pain and high levels of fear of movement were found to have worse treatment outcomes compared to people with low levels of fear of movement. However, our experimental treatment, which includes pain neuroscience education combined with exercise therapy that reintroduces specific movements patients might fear, can decrease this negative influence of fear of movement in these patients.

Isokinetic Trunk Strength in Acute Low Back Pain Patients Compared to Healthy Subjects: A Systematic Review

BACKGROUND

The purpose of this systematic review was to: (I) determine the quality of evidence from studies assessing trunk isokinetic strength in subjects with acute low back pain (ALBP) compared to healthy subjects and (II) establish reference values of isokinetic trunk strength in subjects with ALBP.

METHODOLOGY

Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with trunk, strength and low back pain. Four databases were used: PubMed, Web of Science, Scopus and SPORTDiscus. Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS).

RESULTS

A total of 1604 articles were retrieved, four included in this review. All were evaluated as high risk of bias (Rob). Due to the high Rob and the diversity of protocols, instruments and variables used, it was not possible to determine reference values for subjects with ALBP, we can only establish a range of flexion peak torque (PT) between 175.1 and 89.7 Nm at 60°/s and between 185 and 81.5 Nm at 120°/s, and for extension PT between 240.0 and 91.5 Nm at 60°/s and between 217.5 and 69.2 Nm at 120°/s in subjects with ALBP.

CONCLUSIONS

Due to the low quality of the evidence and the diversity of protocols used when measuring trunk isokinetic strength, it is necessary to carry out new high-quality research to establish reference values of trunk strength in subjects with ALBP.

The Influence of Kinesiophobia on Perceived Disability in Patients With an Upper-Extremity Injury: A Critically Appraised Topic

Clinical Scenario: Kinesiophobia is a common psychological phenomenon that occurs following injury involving fear of movement. These psychological factors contribute to the variability among patients' perceived disability scores following injury. In addition, the psychophysiological, behavioral, and cognitive factors of kinesiophobia have been shown to be predictive of a patient's self-reported disability and pain. Previous kinesiophobia research has mostly focused on lower-extremity injuries. There are fewer studies that investigate upper-extremity injuries despite the influence that upper-extremity injuries can have on an individual's activities of daily living and, therefore, disability scores. The lack of research calls for a critical evaluation and appraisal of available evidence regarding kinesiophobia and its contribution to perceived disability for the upper-extremity. Focused Clinical Question: How does kinesiophobia in patients with upper-extremity injuries influence perceptions of disability and quality of life measurements? Summary of Key Findings: Two cross-sectional studies and one cohort study were included. The first study found a positive relationship between kinesiophobia and a high degree of perceived disability. Another study found that kinesiophobia and catastrophic thinking scores were the most important predictors of perceived upper-extremity disability. The third study found that kinesiophobia contributes to self-reported disability in the shoulder. Clinical Bottom Line: There is moderate evidence that supports the relationship between kinesiophobia and perceived disability, and the relationship between elevated perceptions of disability and increased kinesiophobia scores in patients with an upper-extremity injury. Clinicians should evaluate and monitor kinesiophobia in patients following injury, a condition that can enhance perceptions of disability. An elevated perception of disability can create a cycle of fear that leads to hypervigilance and fear-avoidance behavior. Strength of Recommendation: Consistent findings from reviewed studies suggest there is grade B evidence to support that kinesiophobia is related to an increased perceived disability following upper-extremity injuries.

Low Back Pain-Related Disability Is Associated with Pain-Related Beliefs Across Divergent Non-English-Speaking Populations: Systematic Review and Meta-Analysis

OBJECTIVES

This systematic review and meta-analysis examined relationships between low back pain (LBP)-related disability and pain beliefs, including pain catastrophizing, pain-related fear, self-efficacy, and back pain beliefs, in non-English-speaking populations. Additionally, the effects of selected cultural factors (i.e., language/geographic area) on the strength of relationships were examined.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

Nine databases were searched. Studies included observational or randomized control clinical trials. Eligible studies had to report estimates of the association between pain beliefs and disability. Pooled estimates of correlation coefficients were obtained through random-effects meta-analysis methods.

RESULTS

Fifty-nine studies, (n = 15,383) were included. Moderate correlations were identified between disability and pain self-efficacy (chronic LBP r = -0.51, P ≤ 0.001), between disability and pain catastrophizing (acute LBP r = 0.47, P ≤ 0.001; chronic LBP r = 0.44, P ≤ 0.001), and also between disability and pain-related fear (chronic LBP r = 0.41, P ≤ 0.001). Otherwise, weak correlations were identified between disability and most pain beliefs (range r = -0.23 to 0.35, P ≤ 0.001). Pooled correlation coefficients between disability and all pain beliefs (except the Fear Avoidance Belief Questionnaire-Work subscale) represent medium effects and suggest that lower disability was associated with greater pain self-efficacy, less pain-related fear, less catastrophic thinking, and less negative back pain beliefs about the nature and cause of back pain. Results were consistent across most language groups and geographic regions; few studies reported ethnicity or religion.

DISCUSSION

LBP-related disability was associated with pain-related beliefs, with consistency demonstrated for each pain belief construct across divergent non-English-speaking populations. Further research examining cultural factors, such as ethnicity or religion, and with a more diverse population is warranted.
