Relationship between kinesiophobia and performance in a functional capacity evaluation.

Fear of movement and (re)injury (kinesiophobia) has been postulated to play an important role in the performance in a Functional Capacity Evaluation (FCE). This study was performed to analyze the relationship between kinesiophobia and performance in an FCE. Kinesiophobia and FCE performance of 54 male and 10 female patients (mean age 38.0) suffering chronic low back pain (mean length of episode 9.9 months, 93% off work) were assessed. Kinesiophobia was assessed using the Dutch Version of the Tampa Scale for Kinesiophobia (scale 17-68). A lifting task and an FCE were operationalizations of avoidance. FCE results were transformed into a single measure using the classification of the Dictionary of Occupational Titles (FCE-DOT, scale 1-5). Correlations between the variables were calculated. The results are: kinesiophobia mean 41.6 (SD 7.3), lifting mean 29.5 kg (SD 11.6), FCE-DOT mean 3.6 (SD 0.6). Correlations between kinesiophobia and lifting was r = 0.01 (p = 0.93) and between kinesiophobia and FCE-DOT was rho = -0.04 (p = 0.75). The results indicate that the patients were substantially kinesiophobic, yet they were able to lift a mean of 29.5 kg and were physically able to perform moderate to heavy work. The strength of the correlations was very low. The relationship between kinesiophobia and avoidance, operationalized as lifting and an FCE, could not be confirmed in this study.

Can kinesiophobia predict the duration of neck symptoms in acute whiplash?

OBJECTIVES: In low back pain, clinical studies suggest that kinesiophobia (fear of movement/(re)injury) is important in the etiology of chronic symptoms. In this prospective cohort study, the predictive role of kinesiophobia in the development of late whiplash syndrome was examined. METHODS: Victims of car collisions with neck symptoms who initiated compensation claim procedures with a Dutch insurance company were sent a questionnaire containing symptom-related questions and the Tampa Scale of Kinesiophobia (TSK-DV). Follow-up questionnaires were administered 6 and 12 months after the collision. Survival analysis was used to study the relationship between the duration of neck symptoms and explanatory variables. RESULTS: Of the 889 questionnaires sent, 590 (66%) were returned and 367 used for analysis. The estimated percentage of subjects with neck symptoms persisting 1 year after the collision was 47% (SE 2.7%). In a regression model without symptom-related variables, kinesiophobia was found to be related to a longer duration of neck symptoms (P=0.001). However, when symptom-related information was entered into the model, the effect of kinesiophobia did not reach statistical significance (P=0.089). CONCLUSIONS: Although a higher score on the TSK-DV was found to be associated with a longer duration of neck symptoms, information on early kinesiophobia was not found to improve the ability to predict the duration of neck symptoms after motor vehicle collisions.

The Effect of Robot-Assisted Gait Training on Balance, Gait and Kinesiophobia in Individuals With Post-Stroke Hemiparesis: A Randomized Controlled Trial.

BACKGROUND AND PURPOSE: Robot-assisted gait training (RAGT) is well established for post-stroke gait rehabilitation, but its potential effects on psychological and behavioral outcomes are less clear. This study investigated the effects of adding RAGT to conventional rehabilitation on balance, gait, kinesiophobia, and movement confidence in individuals with post-stroke hemiparesis. METHODS: This single-blind, parallel-group randomized controlled trial included 60 individuals with post-stroke hemiparesis (50-75 years), randomly allocated to an RAGT group (n = 30) or control group (n = 30). Ethical approval was obtained from the Clinical Research Ethics Committee of Istanbul Yeni Yüzyıl University (Approval No. 20.01.2022/05; approval date: 20 January 2022). Both groups received conventional rehabilitation for 8 weeks; the RAGT group additionally received 24 sessions of RAGT. Kinesiophobia was a prespecified study outcome assessed using the Kinesiophobia Causes Scale (KCS); balance, gait, and balance confidence were also assessed. All 60 randomized participants completed follow-up and were analyzed in their assigned groups. RESULTS: Significant group × time interactions were observed for several outcomes, including BBS, TUG duration, 10MWT walking speed, ABC, and KCS total score (p < 0.05). The between-group difference in change for KCS total score was -0.36 (95% CI: -0.51 to -0.21; partial eta squared = 0.292). In post hoc analyses adjusting each outcome for its baseline value, significant group effects remained for BBS, TUG duration, 10MWT walking speed, ABC, KCS biological domain, and KCS total score (p< = 0.031), whereas 10MWT step count and the KCS psychological domain were no longer statistically significant. DISCUSSION: Adding RAGT to conventional rehabilitation was associated with greater improvements in several balance, mobility, walking-speed, balance-confidence, and kinesiophobia outcomes compared with conventional rehabilitation alone. These findings suggest potential additional physical and psychological benefits of incorporating RAGT into post-stroke rehabilitation. However, because the RAGT group received greater overall treatment exposure, the observed between-group differences cannot be attributed solely to the robotic component. The principal contribution of this study is the concurrent evaluation of kinesiophobia and movement confidence alongside physical outcomes.

Kinesiophobia in migraine.

UNLABELLED: Pain aggravation by movement and avoidance of movement (kinesiophobia) is often reported by patients during migraine attacks. Yet its specific contribution to migraine diagnosis is undetermined. To characterize the frequency and severity of kinesiophobia during migraine and its role in the diagnosis of primary headaches, we questioned 150 patients (126 women and 24 men, average age 38.5 yrs) with migraine (n = 111) or tension-type headache (TTH) (n = 39) about aggravation of pain by bending forward, brisk head movements (jolt), and avoidance of movement during the attacks. The degree of pain worsening by each stimulus was measured through a visual analog scale and compared to worsening produced by other sensory stimuli such as light, sound, and smell. The discrimination power of kinesiophobia between migraine and TTH was calculated, using the International Classification of Headache Disorders criteria as gold standard. Sensitivity/specificity of studied symptoms was high in differentiating the 2 headache types: bending forward: 98%/85.7%; jolt: 96.3%/81.6%; and immobility during the attacks: 100%/70%. The degree of kinesiophobia was identical to photo- and phonophobia in migraine patients. We conclude that kinesiophobia discriminates between migraine and TTH. Bending forward and jolt may be useful additional questions to ask patients for the differentiation of headache attacks. PERSPECTIVE: This article evaluates the specific role of movement (movement-induced pain aggravation and avoidance of movement) in primary headaches. Kinesophobia is an easy symptom to screen, explained by migraine pathophysiology, and proved to be a sensitive and specific measure to identify migraine attacks when compared to tension-type headache.

Kinesiophobia among patients with musculoskeletal pain in primary healthcare.

OBJECTIVES: To describe the occurrence of kinesiophobia and to investigate the association between kinesiphobia and pain variables, physical exercise measures and psychological characteristics in patients with musculoskeletal pain. DESIGN: A prospective descriptive study involving 2 selected physiotherapy departments within a primary healthcare setting in the south-west of Sweden. PATIENTS: Included were 140 of 369 (38%) consecutive patients (aged between 18 and 65 years) with musculoskeletal pain. METHODS: Questionnaires including background data, pain variables, physical exercise measures and psychological characteristics were sent to the patients prior to their appointment with the physiotherapist. A simple and a multiple logistic regression model were performed to identify associations among the variables where kinesiophobia was defined as the dependent variable. RESULTS: A high degree of kinesiophobia and psychological distress were observed in approximately 50% of the responders. According to the simple logistic regression analysis the factors that seemed to be associated with kinesiophobia were interference, disability, pain severity, pain intensity, life control, affective distress, depressed mood and solicitous response. The multiple logistic regression analysis showed no significant associations. CONCLUSION: Kinesiophobia is a commonly seen factor among patients with musculoskeletal pain, which ought to be taken into consideration when designing and performing rehabilitation programmes.

Kinesiophobia in chronic fatigue syndrome: assessment and associations with disability.

OBJECTIVES: To investigate aspects of the validity of the total scores of the Tampa Scale for Kinesiophobia (TSK), Dutch Version, which was modified to make it an appropriate questionnaire for the assessment of kinesiophobia (fear of movement) in chronic fatigue syndrome (CFS) patients (the Dutch TSK-CFS), and, using this assessment tool, to examine the associations between kinesiophobia, exercise capacity, and activity limitations and participation restrictions in patients with CFS. DESIGN: Prospective observational studies. SETTING: An outpatient fatigue clinic. PARTICIPANTS: In the first study, 40 patients fulfilling the 1994 US Centers for Disease Control and Prevention (CDC) criteria for CFS were enrolled. The sample of the second study consisted of 51 CDC-defined patients with CSF. INTERVENTIONS: Not applicable. Main outcome measures Study 1: Subjects completed a set of questionnaires; the Utrechtse Coping List (UCL), the Dutch TSK-CFS, and the Dutch Baecke Questionnaire of Habitual Physical Activity. Study 2: All patients completed 2 questionnaires (Chronic Fatigue Syndrome Activities and Participation Questionnaire [CFS-APQ], Dutch TSK-CFS) and performed a maximal exercise stress test on a bicycle ergometer. The heart rate was monitored continuously by use of an electrocardiograph. Metabolic and ventilatory parameters were measured through spirometry. RESULTS: Study 1: The Cronbach alpha coefficient for the individual item scores on the TSK-CFS was .80. The total scores on the Dutch TSK-CFS showed a statistically significant correlation with both the avoidance/abide subscale of the UCL (Spearman rho=.35, P=.029) and the total score of the Baecke Questionnaire (rho=-.45, P=.004). Study 2: The total scores on the Dutch TSK-CFS showed a statistically significant correlation with the total scores on the CFS-APQ (rho=.39, P=.004). No statistically significant associations were observed between the exercise capacity parameters and the total scores on the Dutch TSK-CFS. CONCLUSIONS: These results provide evidence for the internal consistency and the convergent and congruent validity of the scores obtained by use of the Dutch TSK-CFS. Kinesiophobia appears to be associated with activity limitations/participation restrictions but not with exercise capacity in patients with CFS.

Pain catastrophizing and kinesiophobia: predictors of chronic low back pain.

By using a population-based cohort of the general Dutch population, the authors studied whether an excessively negative orientation toward pain (pain catastrophizing) and fear of movement/(re)injury (kinesiophobia) are important in the etiology of chronic low back pain and associated disability, as clinical studies have suggested. A total of 1,845 of the 2,338 inhabitants (without severe disease) aged 25-64 years who participated in a 1998 population-based questionnaire survey on musculoskeletal pain were sent a second questionnaire after 6 months; 1,571 (85 percent) participated. For subjects with low back pain at baseline, a high level of pain catastrophizing predicted low back pain at follow-up (odds ratio (OR) = 1.7, 95% confidence interval (CI): 1.0, 2.8) and chronic low back pain (OR = 1.7, 95% CI: 1.0, 2.3), in particular severe low back pain (OR = 3.0, 95% CI: 1.7, 5.2) and low back pain with disability (OR = 3.0, 95% CI: 1.7, 5.4). A high level of kinesiophobia showed similar associations. The significant associations remained after adjustment for pain duration, pain severity, or disability at baseline. For those without low back pain at baseline, a high level of pain catastrophizing or kinesiophobia predicted low back pain with disability during follow-up. These cognitive and emotional factors should be considered when prevention programs are developed for chronic low back pain and related disability.

Does 'mental kinesiophobia' exist?

In this study the relevance of the concept of mental kinesiophobia (respectively cogniphobia or fear of mental exertion) for clients with chronic stress problems was explored. It was hypothesized that cognitive, chronic stress complaints, such as concentration problems or decreased problem solving abilities, could be catastrophized as signs of heightened personal vulnerability, with a chance of becoming permanent. As a consequence, mental exertion is avoided. This line of reasoning comes from the existing concept of kinesiophobia. This concept describes the avoidance behavior in chronic benign pain patients and refers to their fear of inflicting irreversible bodily damage due to physical exertion.An illustrative case of cogniphobia is presented. In an explorative pilot-study it was demonstrated that chronically stressed clients scored significantly higher on an experimental questionnaire measuring avoidance tendencies for mental exertion, compared with actively working employees. Consequences for treatment and suggestions for further study are discussed.

Evaluating the reliability of multi-item scales: a non-parametric approach to the ordered categorical structure of data collected with the Swedish version of the Tampa Scale for Kinesiophobia and the Self-Efficacy Scale.

OBJECTIVE: To compare the ability of a rank-invariant non-parametric method with that of kappa statistics to evaluate the reliability of the Swedish version of the Tampa Scale for Kinesiophobia and the Self-Efficacy Scale by identifying systematic and random disagreement. The aim was, further, to compare 2 different statistical approaches to obtain a global value from multi-item scales. DESIGN: A test-retest study. SUBJECTS: A total of 46 patients with whiplash-associated disorders were enrolled and 39 (85%) completed the test-retest assessment. METHODS: Data from the multi-item scales were summarized using both sum and median scores. Paired data were evaluated with a rank-invariant statistical method to identify systematic and random disagreement. Data were also evaluated with kappa statistics. RESULTS: The non-parametric approach demonstrated that the Swedish version of the Tampa Scale for Kinesiophobia and the Self-Efficacy Scale are reliable for patients with whiplash-associated disorders. In contrast to the rank-invariant method, kappa statistics provided no information on disagreement between the 2 test occasions. Median scoring improved reliability due to lack of disagreement while the sum scores method was characterized by random individual disagreement. CONCLUSION: This study has increased understanding of the advantages and limitations of 2 non-parametric statistical methods and, it is hoped, will contribute to the development of reliable measurements.

Confirmatory factor analysis of the Tampa Scale for Kinesiophobia: invariant two-factor model across low back pain patients and fibromyalgia patients.

OBJECTIVES: (1) To investigate the factor structure of the Tampa Scale for Kinesiophobia (TSK) in a Dutch-speaking sample of chronic low back pain (CLBP) patients using confirmatory factor analysis, (2) to examine whether the internal structure of the TSK extends to another group of fibromyalgia (FM) patients, and (3) to investigate the stability of the factor structure in both patient groups using multi-sample analysis. PATIENTS AND METHODS: TSK-data from 8 studies collected in Dutch and Flemish chronic pain patients were pooled. For 188 CLBP patients and 89 FM patients, complete data were available. Confirmatory factor analyses were performed to assess 4 models of kinesiophobia, and to examine which factor model provided the best fit. Furthermore, a multi-sample analysis was performed to investigate the stability of the factor structure in both patient groups. RESULTS: For both CLBP and FM patients, the 2-factor model containing the factors "activity avoidance" and "pathologic somatic focus" was superior as compared with the 4-factor model containing the factors "harm," "fear of (re)injury." "importance of exercise," and "avoidance of activity". Moreover, the 2-factor model was found to be invariant across CLBP and FM patients, indicating that this model is robust in both pain samples. DISCUSSION: As the 2-factor structure provided the best fit of the data in both patient samples, we recommend to use this version of the TSK and its 2 subscales in both clinical practice and research. Based on the content of the items, the subscales were labeled "Harm" and "Fear-avoidance."

Fear of movement/injury in the general population: factor structure and psychometric properties of an adapted version of the Tampa Scale for Kinesiophobia.

In recent years, several studies have pointed out the importance of pain-related fear in the development and maintenance of chronic pain. An important instrument for measuring pain-related fear in the context of low back pain is the Tampa Scale for Kinesiophobia (TSK). Recently, a version of this questionnaire has been developed for administration among the general population (TSK-G). To determine the factor structure of the TSK-G, data from a random sample of the Dutch general population were studied separately for people who had had back complaints in the previous year, and people who had been without back complaints. For both groups the TSK-G appeared to consist of one, internally consistent, factor of 12 items. The one-factor TSK-G also appeared valid after comparison with scores on measures of catastrophizing and general health status.

The Tampa Scale for Kinesiophobia: further examination of psychometric properties in patients with chronic low back pain and fibromyalgia.

The present study attempted to replicate the robustness of a two-factor model of the Tampa Scale for Kinesiophobia (TSK) in chronic low back pain (CLBP) patients and fibromyalgia patients, by means of confirmatory factor analysis. Construct and predictive validity of the TSK subscales were also examined. Results clearly indicated that a two-factor model fitted best in both pain samples. These two factors were labelled somatic focus, which reflects the belief in underlying and serious medical problems, and activity avoidance, which reflects the belief that activity may result in (re)injury or increased pain. Construct validity of the TSK and its subscales was supported by moderate correlation coefficients with self-report measures of pain-related fear, pain catastrophising, and disability, predominantly in patients with CLBP. Predictive validity was supported by moderate correlation coefficients with performance on physical performance tests (i.e., lifting tasks, bicycle task) mainly in CLBP patients. Implications of the results are discussed and directions for future research are provided.

Fear of movement: factor structure of the tampa scale of kinesiophobia in patients with fibromyalgia syndrome.

UNLABELLED: Chronic pain patients often report fears that movement will exacerbate their symptoms. The Tampa Scale of Kinesiophobia (TSK) was designed to assess fear of movement. Previous findings with the TSK showed inconsistent factor structures and varied measurement properties. The TSK was completed by a sample of 233 patients with fibromyalgia syndrome who were being evaluated for participation in a rehabilitation program. A principal components analysis initially derived a 5-factor solution. However, the factor structure accounted for less than 50% of the variance, and the internal consistency of the factors was below conventional standards (<0.70). A series of principal components analyses "forcing" different factor structures revealed that the best solution was a single factor solution that contained 4 of the original 17 TSK items, accounting for more than 50% of the variance with adequate internal consistency (alpha =0.71). Inspection of the content of these 4 items, however, suggests that this factor more likely represents catastrophic thinking, rather than fear of movement. Nevertheless, for patients with fibromyalgia syndrome, a 4-item TSK appears to retain the most acceptable factor solution while also maintaining adequate internal consistency. PERSPECTIVE: Although the TSK is one of the most commonly used measures of fear of movement, the present study using the TSK with a sample of patients with fibromyalgia syndrome suggests that the measurement properties of the TSK are problematic. Recommendations for use of the TSK are provided.

Psychometric properties of the TSK-11: a shortened version of the Tampa Scale for Kinesiophobia.

The Tampa Scale for Kinesiophobia (TSK) is one of the most frequently employed measures for assessing pain-related fear in back pain patients. Despite its widespread use, there is relatively little data to support the psychometric properties of the English version of this scale. This study investigated the psychometric properties of the English version of the TSK in a sample of chronic low back pain patients. Item analysis revealed that four items possessed low item total correlations (4, 8, 12, 16) and four items had response trends that deviated from a pattern of normal distribution (4, 9, 12, 14). Consequently, we tested the psychometric properties of a shorter version of the TSK (TSK-11), having excluded the six psychometrically poor items. The psychometric properties of this measure were compared to those of the original TSK. Both measures demonstrated good internal consistency (TSK: alpha=0.76; TSK-11: alpha=0.79), test-retest reliability (TSK: ICC=0.82, SEM=3.16; TSK-11: ICC=0.81, SEM=2.54), responsiveness (TSK: SRM=-1.19; TSK-11: SRM=-1.11), concurrent validity and predictive validity. In respect of specific cut-off scores, a reduction of at least four points on both measures maximised the likelihood of correctly identifying an important reduction in fear of movement. Overall, the TSK-11 possessed similar psychometric properties to the original TSK and offered the advantage of brevity. Further research is warranted to investigate the utility of the new instrument and the cut-off scores in a wider group of chronic pain patients in different clinical settings.

Fear of movement/(re)injury in chronic pain: a psychometric assessment of the original English version of the Tampa scale for kinesiophobia (TSK).

The Tampa scale for kinesiophobia (TSK) was developed to measure fear of movement/(re)injury in chronic pain patients. Although studies of the Dutch adaptation of the TSK have identified fear of movement/(re)injury as an important predictor of chronic pain, pain-related avoidance behaviour, and disability, surprisingly little data on the psychometric properties of the original English version of the TSK are available. The present study examined the reliability, construct validity and factor structure of the TSK in a sample of chronic pain patients (n=200) presenting for an interdisciplinary functional restoration program. Consistent with prior evaluations of the Dutch version of the TSK, the present findings indicate that the English TSK possesses a high degree of internal consistency and is positively associated with related measures of fear-avoidance beliefs, pain catastrophizing, pain-related disability and general negative affect. The TSK was not related to individual differences in physical performance testing as assessed using standardised treadmill and lifting tasks. Confirmatory factor analyses suggest that the TSK is best characterized by a three-factor trait method model that includes all 17 of the original scale items and takes into account the distinction between positively and negatively keyed items. The results of the present study provide important details regarding the psychometric properties of the original English version of the TSK and suggest that it may be unnecessary to remove the negatively keyed items in an attempt to improve scale validity.

Psychometric properties of the Tampa Scale for kinesiophobia and the fear-avoidance beliefs questionnaire in acute low back pain.

The transition from acute to chronic low back pain (LBP) is influenced by many interacting factors. Pain-related fear, as measured by the Tampa Scale for Kinesiophobia (TSK) and the Fear-Avoidance Beliefs Questionnaire (FABQ), is one of these factors. The objectives of this study were to investigate, in a population with acute LBP, the reliability of TSK and FABQ through evaluation of the internal consistency, the test-retest reliability, and the concurrent validity between TSK and FABQ. One hundred and Seventy-Six patients suffering LBP for no longer than 4 weeks completed a Visual Analogue Scale for pain (VAS), the TSK, the FABQ, and a socio-demographic questionnaire. Each patient completed the VAS, TSK, and FABQ twice within 24 h. Internal consistency of TSK and FABQ scores range from alpha=0.70 to 0.83. Test-retest reliability ranges from r(s)=0.64 to 0.80 (P<0.01). Concurrent validity is moderate, ranging from r(s) =0.33 to 0.59 (P<0.01). It may be concluded that in a population with acute LBP, both the TSK and the FABQ are reliable measures of pain-related fear. In the clinical setting they may provide the practitioner a means of identifying pain-related fear in a patient with acute LBP.

Chronic fatigue syndrome: lack of association between pain-related fear of movement and exercise capacity and disability.

BACKGROUND AND PURPOSE: Patients who experience pain, a symptom of chronic fatigue syndrome (CFS), often exhibit kinesiophobia (irrational fear of movement). The purpose of this study was to examine whether pain-related fear of movement is associated with exercise capacity, activity limitations, or participation restrictions in patients with CFS who experience widespread pain. SUBJECTS AND METHODS: Sixty-four subjects met the inclusion criteria. All subjects fulfilled the 1994 Centers for Disease Control and Prevention case definition for CFS and experienced widespread myalgias or arthralgias. The subjects completed the Tampa Scale for Kinesiophobia-Dutch Version (TSK-DV) and the Dutch Chronic Fatigue Syndrome-Activities and Participation Questionnaire (CFS-APQ). They then performed a maximal exercise test on a bicycle ergometer. Heart rate was monitored continuously by use of an electrocardiograph. Ventilatory factors were measured through spirometry. Correlations between the TSK-DV scores and both the exercise capacity data and the CFS-APQ scores were assessed using the Spearman rank correlation coefficient. Using the Mann-Whitney U test, the TSK-DV scores were compared between subjects who performed a maximal exercise stress test and those who did not perform the test. RESULTS: Forty-seven subjects (73.4%) attained a total score of greater than 37 on the TSK-DV, indicating high fear of movement. Neither the exercise capacity data nor the CFS-APQ scores indicated a correlation with the TSK-DV scores (n=64). Subjects who did not perform a maximal exercise capacity test had more fear of movement (median TSK-DV score=43.0, interquartile range=10.3) compared with those who did perform a maximal exercise capacity test (median TSK-DV score=38.0, interquartile range=13.2; Mann-Whitney U-test score=322.5, z=-1.974, P=.048), but the correlation analysis was unable to reveal an association between exercise capacity and kinesiophobia in either subgroup. DISCUSSION AND CONCLUSION: These results indicate a lack of correlation between kinesiophobia and exercise capacity, activity limitations, or participation restrictions, at least in patients with CFS who are experiencing widespread muscle or joint pain.

Comparison of a high-intensity and a low-intensity lumbar extensor training program as minimal intervention treatment in low back pain: a randomized trial.

In a randomized, observer-blinded trial, the effectiveness of 3-month high-intensity training (HIT) of the isolated lumbar extensors was compared to low-intensity training (LIT). Eighty-one workers with nonspecific low back pain longer than 12 weeks were randomly assigned to either of the two training programs. Training sessions were performed on a modified training device that isolated the lower back extensors. Total intervention time was limited to 5-10 min (one or two training sessions) per week. Training effects were assessed in terms of changes in self-rated degree of back complaints, functional disability, and general, physical and mental health. Secondary outcomes in this study were muscle strength and fear of moving the back (kinesiophobia). Outcomes were evaluated at 1,2, 3, 6, and 9 months after randomization. The results showed that the two treatment programs led to comparable improvements in all outcome measures, except for mean isometric strength at 1, 2, 3, 6, and 9 months and kinesiophobia score at 2 and 9 months of follow-up. The high-intensity training group showed a higher strength gain (24 to 48 Nm) but a smaller decline in kinesiophobia (2.5 and 3.4 points, respectively), compared to the low-intensity training group. It can be concluded that high-intensity training of the isolated back extensors was not superior to a non-progressive, low-intensity variant in restoring back function in nonspecific (chronic) low back pain. In further research, emphasis should be put on identifying subgroups of patients that will have the highest success rate with either of these training approaches.
