A short tool to screen self-care preparedness: cross-sectional study in general practice.

BACKGROUND: Self-care is crucial in the prevention and treatment of chronic diseases. It is important to identify patients who need support with self-care. OBJECTIVES: This study introduces a self-care preparedness index (SCPI) and examines its associations with health-related quality of life (HRQoL) and other outcomes. METHODS: A cross-sectional study of adults (n = 301) with hypertension, coronary artery disease, or diabetes in primary health care. Based on the self-care questionnaire, SCPI was formed. A higher SCPI value indicated better self-care preparedness. We examined correlations and a hypothesis of linearity between SCPI and HRQoL (15D), depressive symptoms (BDI), patient activation (PAM), and health-related outcomes (self-rated health, life satisfaction, physical activity, body mass index [BMI], waist, low-density lipoprotein). Exploratory factor analysis was used to test the construct validity of SCPI. RESULTS: A total of 293 patients with a mean age of 68 (54.3% women) were included in the analysis. BDI, BMI, and waist had a negative linear trend with SCPI. Self-rated health, physical activity, patient activity, and life satisfaction had a positive linear trend with SCPI. SCPI correlated with HRQoL (r = 0.31 [95% CI: 0.20 to 0.41]). Exploratory factor analysis of the SCPI scores revealed 3 factors explaining 82% of the total variance. CONCLUSIONS: SCPI seems to identify individuals with different levels of preparedness in self-care. This provides means for health care providers to individualize the levels of support and counselling. SCPI seems to be a promising tool in primary health care but needs further validation before use in large scale trials or clinical practice.

Self-care is essential in the prevention and treatment of many diseases. Self-care means taking care of the treatment of chronic condition with the support of health care professionals. Patients have different capabilities and resources to perform self-care and a varying need for support and counselling. Identifying self-care preparedness might help health care providers to support patients more appropriately. This study introduced a short tool for screening self-care preparedness in primary health care. We used the data of 293 adults with hypertension, diabetes, or coronary artery disease in primary health care in Finland between 2017 and 2018. The patients' mean age was 68 (54.3% women). Low self-care preparedness was reported by 79 (27.0%), moderate by 115 (39.2%), and high by 99 (33.8%) patients. Patients with lower self-care preparedness were more obese, had lower physical activity, more depressive symptoms, lower self-rated health, lower quality of life, lower patient activation, and lower satisfaction with life. This study provided preliminary information that such a tool could be used to identify preparedness for self-care.

Depressive symptoms decrease health-related quality of life of patients with coronary artery disease and diabetes: a 12-month follow up study in primary care.

OBJECTIVE: Health-related quality of life (HRQoL) is a multidimensional patient-related outcome. Less is known about the role of depressive symptoms on HRQoL in chronic diseases. This follow-up study analyzed depressive symptoms' association with HRQoL change measured with 15D in patients with chronic diseases. DESIGN AND SETTING: A total of 587 patients from the Siilinjärvi Health Center, Finland were followed up due to the treatment of hypertension (HA), coronary artery disease (CAD) or diabetes (DM). Depressive symptoms were based on Beck Depression Inventory (BDI) (BDI ≥10 =depressive symptoms). HRQoL was assessed at the baseline and after 12 months. RESULTS: There were 244 patients with HA (mean age 70 years, 59% women); 103 patients (72 years, 38%) with CAD and 240 with DM (67 years, 52%). The change from baseline to the 12-month follow-up in 15D was significantly different between patients without and with depressive symptoms in CAD (p < 0.001) and DM (p = 0.024). In CAD with depressive symptoms, the change was -0.064 (95% CI: -0.094 to -0.035) and in DM -0.018 (95% CI: -0.037 to 0.001). In the 15 HRQoL dimensions of 15D, a depressive symptoms-related decrease was found in three dimensions with HA, in 9 with CAD and in 7 with DM. As a function of the BDI at baseline, the 15D score decreased significantly among patients with CAD and DM. CONCLUSIONS: Depressive symptoms impact negatively on future HRQoL among primary care patients with coronary artery disease and diabetes emphasizing that mood should be acknowledged in their care and follow-up. TRIAL REGISTRATION: Clinical Trials registration number: NCT02992431, registered December 14th 2016.

Health-related quality of life (HRQoL) is an important dimension of the quality and effectiveness of health care and an important predictor of mortality and morbidity.The main finding was that baseline depressive symptoms were associated with a decrease in the health-related quality of life after 12 months of follow-up, particularly in patients with coronary artery disease and diabetes.Beginning from the lowest scores, the severity of baseline depressive symptoms had a significant relationship with the level of deterioration in HRQoL among patients with coronary artery disease and diabetes.A significant decrease in HRQoL related to depressive symptoms was found in various different dimensions of HRQoL.

Randomized controlled study of the impact of a participatory patient care plan among primary care patients with common chronic diseases: a one-year follow-up study.

BACKROUND: Chronic diseases and multimorbidity are common in the ageing population and affect the health related quality of life. Health care resources are limited and the continuity of care has to be assured. Therefore it is essential to find demonstrable tools for best treatment practices for patients with chronic diseases. Our aim was to study the influence of a participatory patient care plan on the health-related quality of life and disease specific outcomes related to diabetes, ischemic heart disease and hypertension. METHODS: The data of the present study were based on the Participatory Patient Care Planning in Primary Care. A total of 605 patients were recruited in the Siilinjärvi Health Center in the years 2017-2018 from those patients who were followed up due to the treatment of hypertension, ischemic heart disease or diabetes. Patients were randomized into usual care and intervention groups. The intervention consisted of a participatory patient care plan, which was formulated in collaboration with the patient and the nurse and the physician during the first health care visit. Health-related quality of life with the 15D instrument and the disease-specific outcomes of body mass index (BMI), low density lipoprotein cholesterol (LDL-C), hemoglobin A1c (HbA1C) and blood pressure were assessed at the baseline and after a one-year follow-up. RESULTS: A total of 587 patients with a mean age of 69 years were followed for 12 months. In the intervention group there were 289 patients (54% women) and in the usual care group there were 298 patients (50% women). During the follow-up there were no significant changes between the groups in health-related quality and disease-specific outcomes. CONCLUSIONS: During the 12-month follow-up, no significant differences between the intervention and the usual care groups were detected, as the intervention and the usual care groups were already in good therapeutic equilibrium at the baseline.

Relationship between patient activation measurement and self-rated health in patients with chronic diseases.

BACKGROUND: In the aging population, chronic diseases and multimorbidity are common. Therefore, it is important to engage patients in their self-care. The aim of this study was to analyze the relationship between activity in self-care and self-rated health among primary care patients with chronic diseases. METHODS: The data of the present study were derived from a research project on the Participatory Patient Care Planning in Primary Care (4PHC). A total of 605 patients were recruited in the Siilinjärvi Health Center from those patients who were being monitored due to the treatment of hypertension, ischemic heart disease or diabetes. We evaluated the level of patient's activity in self-care with the Patient Activation Measurement (PAM). Self-rated health (SRH) was measured with the 5-item Likert scale. An adjusted hypothesis of linearity across categories of PAM and self-rated health was estimated using analysis of covariance (ANCOVA). RESULTS: It was found that 76 patients had low activity, 185 had moderate while 336 patients had high activity as measured with PAM. Patients with the highest activity were younger, less depressed, had a lower body mass index and a higher level of physical activity than those with the lower activity. Correspondingly, good SRH was perceived by 29, 45 and 67% of the patients in these three PAM groups adjusted with sex, age, depressive symptoms (BDI) and number of diseases. There was a significant linear trend (adjusted with age, number of diseases and depressive symptoms) between SRH and PAM, p < 0.001. CONCLUSIONS: Activity in self-care had an independent, linear relationship with the self-rated health. The present findings suggest that Patient Activation Measurement has the potential to categorize the patients according to their perceived health and their needs related to their disease management and self-care. The present results warrant longitudinal studies on the impact of promoting patient activation levels. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02992431 .

Multiple psychological factors predict pain and disability among community-dwelling knee osteoarthritis patients: a five-year prospective study.

OBJECTIVE: To identify predictors of long-term pain and disability in knee osteoarthritis. DESIGN: A longitudinal cohort study of five years. SETTING: Primary care providers. SUBJECTS: In all, 108 patients (mean age = 63.6 years, standard deviation (SD) = 7.2 years) with knee pain (⩾40 mm on a 100 mm visual analogue scale in the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index pain scale) and radiographic grading (Kellgren-Lawrence: 2-4) of knee osteoarthritis who participated in a randomized controlled trial. MAIN MEASURES: Disease-specific pain and functioning were assessed using the corresponding WOMAC subscales. Generic functioning was assessed by the RAND-36 subscales for function and physical and mental component summary scores. Possible baseline predictors for these outcomes were (1) demographic and disease-related variables and (2) psychological variables of mood (anxiety, depression), pain-related cognitions (pain self-efficacy, pain catastrophizing, kinesiophobia), and positive resource factors (life satisfaction, sense of coherence). RESULTS: Multivariate linear mixed model analyses revealed that minimal anxiety at baseline predicted significantly better results for pain (WOMAC, P = 0.019) and function (WOMAC, P = 0.001, RAND-36 function P = 0.001). High pain self-efficacy predicted significantly better scores in RAND-36 function (P = 0.006), physical (P = 0.004) and mental (P = 0.001) component summaries. Pain catastrophizing predicted higher pain (P = 0.015), whereas fear of movement predicted poorer functioning in RAND-36 physical (P = 0.016) and mental (P = 0.009) component summaries. Those satisfied with life reported higher scores in RAND-36 function (P = 0.002) and mental component summary (P = 0.041). A low number of comorbidities predicted significantly better results in pain (WOMAC P = 0.019) and function (WOMAC P = 0.033, RAND-36 P = 0.009). CONCLUSION: Anxiety, pain-related cognitions, and psychological resources predict symptoms in knee osteoarthritis in the long term.

Effect of metabolic state on implicit and explicit responses to food in young healthy females.

Recent neuroscience research has delineated key psychological components of reward: wanting, liking and learning. Each component is further divided into explicit and implicit processes. While explicit processes are consciously experienced, implicit processes are not always directly accessible to conscious inspection. In the present study, we investigated the effect of metabolic state on implicit and explicit responses and their relationship in food context, especially when foods and visually matched non-food items are contrasted, and when foods in a sole food context but differing in energy content (high-energy - low-energy) or taste (sweet - savoury) were contrasted. Sixty healthy non-obese females participated in the study in fasted and fed states. Three Implicit Association Tests were used to assess implicit associations. Explicit liking and wanting ratings were assessed by visual analogue scales. In the implicit food-non-food context, food was preferred over non-food items both in fasted and fed states, though the strength of implicit associations declined significantly from fasted to fed state. However, the direction or strength of implicit associations was not significantly different between the metabolic states when comparing concepts within food context only, differing in energy content or taste. Instead, explicit responses reflected the change in the metabolic state in a manner consistent with alliesthesia and sensory-specific satiety. The results of the present study suggest that implicit associations are relatively resistant to acute change in the metabolic condition compared to explicit ratings, which shift more readily according to the fasted-fed continuum. The shift in the prevailing metabolic state was, however, reflected in the strength of implicit responses towards food in relation to non-food items, yet in the sole food contexts implicit associations were comparable between the fasted and fed states.

Metabolic state as a modulator of neural event-related potentials for food stimuli in an implicit association test.

The Implicit Association Test (IAT) has become a ubiquitous measure of implicit associations or preferences in several fields of research, including research related to food choices. The neural dynamics of the IAT have been explored in several contexts, but in a food-related IAT with stimuli of natural motivational value they are yet to be studied. Additionally, the effect of metabolic state on them is poorly known. The present study examined the event-related potentials (ERP) in healthy non-obese females (n = 32) while they performed a food-related IAT in two sessions, in a fasted state and after a meal. The results showed differences in the ERP components N400, P3 and LPP by congruence categories. Additionally, the individual N400 and LPP deflections correlated strongly with individual IAT effects. ERP deflections were weaker in the fasted state than after the meal despite greater implicit hedonic motivation towards food in the fasted state. In conclusion, the results suggest that ERPs reflect the IAT effect. The N400, P3 and LPP components were evoked in a food-related IAT in a similar way observed in IAT tests in other contexts, reflecting a difference in meaning and motivation between congruence categories. The strong correlations of individual IAT effect with individual N400 and LPP deflections further suggests that the food-related IAT effect strength reflects the size of implicit food bias seen in neural deflections. Moreover, fasting increased implicit hedonic motivation towards food, but likely reduced cognitive resources at the same time. This could have made it harder to determine the value of novel, task-relevant stimuli, whereas it became easier postprandially and with practice.

Preoperative sense of coherence associated with the 10-year outcomes of lumbar spinal stenosis surgery.

A prospective 10-year follow-up study was conducted to determine the significance of the preoperative sense of coherence, with respect to the preoperative and 10-year clinical characteristics, among lumbar spinal stenosis patients ( N = 99). In addition, the predictive value of the preoperative sense of coherence regarding the 10-year surgery outcome was also evaluated. In a logistic regression analysis, a weak preoperative sense of coherence and low functional ability predicted the patients' functional ability 10 years after the surgery. Moreover, those patients with weak sense of coherence before surgery showed poorer functional ability 10 years after the surgery, but not preoperatively. A weak preoperative sense of coherence seems to associate with poorer long-term outcome after surgery; therefore, various rehabilitation strategies are discussed.

Pain self-efficacy moderates the association between pain and somatization in a community sample.

Background and aims Pain is a common condition. However, only a minority of people experiencing pain develop a chronic pain problem. Factors such as somatization, pain self-efficacy and lack of psychological well-being affect the risk of pain chronicity and pain-related disability. However, research on protective pain-related psychological factors in populations without chronic pain is scarce. We aim to examine if pain self-efficacy attenuates the associations between pain and both anxiety and somatization in a community sample. Methods In a cross-sectional study, 211 participants from a community sample responded to measures of average pain over the last 3 months, anxiety, somatization, and pain self-efficacy. The possibility of moderation effects were tested with a series of regression analyses. Results The association between pain and anxiety was not moderated by pain self-efficacy. In contrast, pain self-efficacy moderated the relation of pain and somatization. The interaction explained 3% of the variance in somatization, in addition to the independent effects of pain and self-efficacy (F(1,207)=5.65, p<0.025). Among those in the bottom quartile of pain self-efficacy, the association between pain and somatization was moderate or strong (r=0.62, p<0.01), whereas for those in the top quartile the association was modest (r=0.11, p>0.05). Conclusions The results are partly consistent with the hypothesis that pain self-efficacy attenuates the associations between pain and pain chronification risk factors in a relatively healthy community sample. Should further preferably longitudinal studies replicate the findings, the role pain self-efficacy as a protective factor needs to be explicated in theoretical models of pain chronification. Implications The findings are consistent with the notion that clinicians should promote patient's pain self-efficacy in acute and sub-acute pain conditions especially when the individual is prone to somatization. However, more prominent clinical implications require studies with longitudinal designs.

Heart rate variability and occupational stress-systematic review.

The aim of this systematic review was to explore studies regarding association between occupational stress and heart rate variability (HRV) during work. We searched PubMed, Web of Science, Scopus, Cinahl and PsycINFO for peer-reviewed articles published in English between January 2005 and September 2017. A total of 10 articles met the inclusion criteria. The included articles were analyzed in terms of study design, study population, assessment of occupational stress and HRV, and the study limitations. Among the studies there were cross-sectional (n=9) studies and one longitudinal study design. Sample size varied from 19 to 653 participants and both females and males were included. The most common assessment methods of occupational stress were the Job Content Questionnaire (JCQ) and the Effort-Reward Imbalance (ERI) questionnaire. HRV was assessed using 24 h or longer Holter ECG or HR monitoring and analyzed mostly using standard time-domain and frequency-domain parameters. The main finding was that heightened occupational stress was found associated with lowered HRV, specifically with reduced parasympathetic activation. Reduced parasympathetic activation was seen as decreases in RMSSD and HF power, and increase in LF/HF ratio. The assessment and analysis methods of occupational stress and HRV were diverse.

Adolescents' lived experiences of making health choices: an ethical point of view.

This study describes and interprets adolescents' lived experiences of their rights, duties and responsibilities in relation to their health choices. Fourteen focus group interviews with 67 adolescents aged 15 and 16 were conducted and analysed using the phenomenological hermeneutical method. Adolescents' lived experiences of their rights in relation to their health choices were described as things that were allowed. Duties and responsibilities were perceived as something that they were required to carry out for their own health or other people's health. Although their experiences of rights, duties and responsibilities overlapped, they referred to different aspects of their health choices. Adolescents viewed their rights, duties and responsibilities in the wider context, with parents and society defining their opportunities to make independent choices. We found that ethical considerations influenced adolescents' choices and, the opportunities to exercise their rights, duties and responsibilities varied. Further consideration and recognition of these issues are needed.

Depression is associated with the long-term outcome of lumbar spinal stenosis surgery: a 10-year follow-up study.

BACKGROUND CONTEXT: Depression is associated with greater postoperative disability in patients with lumbar spinal stenosis (LSS). No previous studies have reported the association in a 10-year follow-up. PURPOSE: To evaluate the association between preoperative and postoperative depressive symptoms and the surgical outcome among patients with LSS in a 10-year follow-up. In addition, we examined the effects of the depressive burden on the surgical outcome. DESIGN: A prospective observational follow-up study. PATIENT SAMPLE: A total of 102 patients with LSS underwent decompressive surgery, and 72 of the original sample participated in the 10-year follow-up study. OUTCOME MEASURES: Self-report measures: the Oswestry Disability Index (ODI) and visual analog scale (VAS). METHODS: Data were collected using a questionnaire that was administered seven times during the study period. Depressive symptoms were measured with the Beck Depressive Inventory (BDI). The depressive burden was calculated by summing the preoperative and all follow-up BDI scores. Statistical analysis included cross-sectional group comparisons and linear mixed models. The authors report no conflicts of interest related to this work. RESULTS: The high depressive burden group had a poorer outcome for pain, disability, and the walking distance at the 10-year follow-up. In linear mixed models, a higher preoperative BDI score associated with higher disability. Furthermore, higher postoperative BDI scores and the depressive burden were associated with higher disability and pain in the 10-year follow-up. CONCLUSIONS: Patients with LSS with even slightly elevated depressive symptoms have an increased risk of postoperative pain and disability in a 10-year follow-up. To improve the surgical outcome among these patients, screening for depression both preoperatively and during the rehabilitation following surgery is important.

Low sense of coherence during postoperative recovery is associated with a poorer lumbar spinal stenosis - surgical outcome: A 5-year follow-up study.

This study investigated the association between the 3-month postoperative sense of coherence and the 5-year postoperative outcome of decompressive surgery for lumbar spinal stenosis. The participants with a lower sense of coherence at the 3-month follow-up had a poorer functional ability and lower satisfaction with surgery, higher pain ratings, lower life satisfaction and more depressive symptoms 5 years postoperatively. A low 3-month sense of coherence associated with greater pain and a poorer functional ability 5 years postoperatively. Evaluating sense of coherence and depressive symptoms in patients who have had lumbar spinal stenosis surgery may help in identifying those in need of enhanced support for postoperative recovery.

Determinants of pain and functioning in knee osteoarthritis: a one-year prospective study.

OBJECTIVE: To identify predictors of pain and disability in knee osteoarthritis. DESIGN: A one-year prospective analysis of determinants of pain and functioning in knee osteoarthritis. STUDY SETTING: Primary care providers in a medium-sized city. PATIENTS: A total of 111 patients aged from 35 to 75 with clinical symptoms and radiographic grading (Kellgren-Lawrence 2-4) of knee osteoarthritis who participated in a randomized controlled trial. MAIN MEASURES: The outcome measures were self-reported pain and function, which were recorded at 0, 3 and 12 months. Disease-specific pain and functioning were assessed using the pain and function subscales of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. Generic physical and mental functioning were assessed using the RAND-36 subscales for function, and physical and mental component summary scores. Possible baseline predictors for these outcomes were 1) demographic, socioeconomic and disease-related variables, and 2) psychological measures of resources, distress, fear of movement and catastrophizing. RESULTS: Multivariate linear mixed model analyses revealed that normal mood at baseline measured with the Beck Anxiety Inventory predicted significantly better results in all measures of pain (WOMAC P=0.02) and function (WOMAC P=0.002, RAND-36 P=0.002) during the one-year follow-up. Psychological resource factors (pain self-efficacy P=0.012, satisfaction with life P=0.002) predicted better function (RAND-36). Pain catastrophizing predicted higher WOMAC pain levels (P=0.013), whereas fear of movement (kinesiophobia) predicted poorer functioning (WOMAC P=0.046, RAND-36 P=0.024). CONCLUSIONS: Multiple psychological factors in people with knee osteoarthritis pain are associated with the development of disability and longer term worse pain.

Life dissatisfaction is associated with depression and poorer surgical outcomes among lumbar spinal stenosis patients: a 10-year follow-up study.

Life satisfaction is associated with overall somatic health and the short-term surgical outcome in lumbar spinal stenosis (LSS) patients. In this study, the long-term relationship between life satisfaction and the surgical outcome in LSS patients was investigated in a 10-year follow-up. This prospective clinical study included 102 LSS patients who underwent decompressive surgery. They completed a set of questionnaires first preoperatively and then 6 times postoperatively (at 3 and 6 months, and at 1, 2, 5 and 10 years). The final study population at the 10-year follow-up comprised 72 patients. A four-item life satisfaction scale was used to measure global life satisfaction. The sum of all seven life satisfaction scores provided a measure of the life dissatisfaction burden over the entire 10-year follow-up. Depression was measured using the Beck Depression Inventory. The surgical outcome was evaluated using the Oswestry Disability Index, pain evaluation (visual analogue scale), self-reported walking capacity and overall satisfaction with the surgery. Both preoperative life dissatisfaction and the long-term life dissatisfaction burden were associated with poorer 10-year surgical outcomes (i.e. Oswestry Disability Index and visual analogue scale) in logistic regression analyses. Life dissatisfaction was also associated with symptoms of depression. Monitoring subjective well-being, especially life satisfaction and mood, in LSS patients before and after surgery may help in detecting those at risk of a poorer long-term surgical outcome.

Development and preliminary validation of a Finnish version of the Eating Disorder Examination Questionnaire (EDE-Q).

BACKGROUND: Eating behaviour can be viewed as a continuum, ranging from extremely restrictive to extremely disinhibited eating. Valid and reliable instruments are needed to ensure detection of individuals with risk for eating disorders (ED). Self-report methods are the most feasible, cost, and time efficient. One of the most widely used self-reports is the Eating Disorder Examination Questionnaire (EDE-Q). AIM: The aim of this study was to develop a Finnish version of the EDE-Q version 6.0 and to assess its psychometric properties in adolescents, adults, and ED patients. METHODS: The present study utilized data from three different samples: adolescents (n = 242), adults (n = 133), and ED patients (n = 52). The patient group comprised different EDs, but individual ED diagnoses were not studied separately. Data was collected January 2014 through June 2015. RESULTS: The Finnish version of the EDE-Q showed acceptable-to-excellent internal consistency on all sub-scales in all three samples and discriminated patients from healthy individuals. Female participants generally scored higher than male and sex differences were more pronounced among the younger age group. CONCLUSIONS: The Finnish version of the EDE-Q can, based on this study, be regarded as reliable, valid, and functional. Further studies are needed to evaluate the population norms and to test the validity in individual ED diagnoses.

Effectiveness of a cognitive-behavioural group intervention for knee osteoarthritis pain: a randomized controlled trial.

OBJECTIVE: To assess the effectiveness of a six week cognitive-behavioural group intervention in patients with knee osteoarthritis pain. DESIGN: Single-blinded randomized controlled trial. STUDY SETTING: Primary care providers in a medium-sized city in Finland. PATIENTS: A total of 111 participants aged from 35 to 75 with clinical symptoms and radiographic grading (Kellgren-Lawrence 2-4) of knee osteoarthritis were included. INTERVENTIONS: In the intervention group, 55 participants attended a cognitive-behavioural training programme for pain management with six weekly group sessions supervised by a psychologist and a physiotherapist. Concurrently, they and the 56 participants of the control group continued in ordinary GP care that was not altered by the study. MAIN MEASURES: The primary outcome on three-month and 12-month follow-up was the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis index pain subscale. Secondary outcome measures included self-reports of pain and physical function, health-related quality of life, and a comprehensive set of psychological questionnaires. RESULTS: Mixed model results showed no significant differences between the intervention and control group for any measures of pain or function. A significant difference between the groups was found in the Pain Self-Efficacy Questionnaire (Pr = 0.022) in favour of the control group, and in the RAND-36 emotional well-being subscale in favour of the intervention group (Pr = 0.038). Conventional group comparisons of mean follow-up values showed no significant differences in any of the outcome variables. CONCLUSION: This trial could not confirm the hypothesized advantage of a cognitive-behavioural training programme over ordinary GP care in knee osteoarthritis pain patients.

Visually assessed severity of lumbar spinal canal stenosis is paradoxically associated with leg pain and objective walking ability.

BACKGROUND: Lumbar spinal stenosis (LSS) is the common term used to describe patients with symptoms related to the anatomical reduction of the lumbar spinal canal size. However, some subjects may have a markedly narrowed canal without any symptoms. This raises the question of what is the actual role of central canal stenosis in symptomatic patients. The purpose of this study was to compare radiological evaluations of LSS, both visually and quantitatively, with the clinical findings of patients with LSS. METHODS: Eighty patients [mean age 63 (11) years, 44% male], with symptoms severe enough to indicate LSS surgery, were included in this prospective single-center study. Lumbar magnetic resonance imaging was performed and one experienced neuroradiologist classified patients into three groups: 0 = normal or mild stenosis, 1 = moderate stenosis, and 2 = severe stenosis. In addition, the same observer measured the minimal dural sac area level by level from the inferior aspect of L1 to the inferior aspect of S1. The association between radiological and clinical findings were tested with Oswestry Disability Index, overall visual analog pain scale, specific low back pain, specific leg pain, Beck Depression Inventory, and walking distance on treadmill exercise test. RESULTS: In the visual classification of the central spinal canal, leg pain was significantly higher and walking distance achieved was shorter among patients with moderate central stenosis than in patients with severe central stenosis (7.33 (2.29) vs 5.80 (2.72); P = 0.008 and 421 (431) m vs 646 (436) m; P = 0.021, respectively). Patients with severe stenosis at only one level also achieved shorter walking distance than patients with severe stenosis of at least two levels. No correlation between visually or quantitatively assessed stenosis and other clinical findings was found. CONCLUSIONS: There is no straightforward association between the stenosis of dural sac and patient symptoms or functional capacity. These findings indicated that dural sac stenosis is not the single key element in the pathophysiology of LSS.

Preoperative MRI findings predict two-year postoperative clinical outcome in lumbar spinal stenosis.

PURPOSE: To study the predictive value of preoperative magnetic resonance imaging (MRI) findings for the two-year postoperative clinical outcome in lumbar spinal stenosis (LSS). METHODS: 84 patients (mean age 63±11 years, male 43%) with symptoms severe enough to indicate LSS surgery were included in this prospective observational single-center study. Preoperative MRI of the lumbar spine was performed with a 1.5-T unit. The imaging protocol conformed to the requirements of the American College of Radiology for the performance of MRI of the adult spine. Visual and quantitative assessment of MRI was performed by one experienced neuroradiologist. At the two-year postoperative follow-up, functional ability was assessed with the Oswestry Disability Index (ODI 0-100%) and treadmill test (0-1000 m), pain symptoms with the overall Visual Analogue Scale (VAS 0-100 mm), and specific low back pain (LBP) and specific leg pain (LP) separately with a numeric rating scale from 0-10 (NRS-11). Satisfaction with the surgical outcome was also assessed. RESULTS: Preoperative severe central stenosis predicted postoperatively lower LP, LBP, and VAS when compared in patients with moderate central stenosis (p<0.05). Moreover, severe stenosis predicted higher postoperative satisfaction (p = 0.029). Preoperative scoliosis predicted an impaired outcome in the ODI (p = 0.031) and lowered the walking distance in the treadmill test (p = 0.001). The preoperative finding of only one stenotic level in visual assessment predicted less postoperative LBP when compared with patients having 2 or more stenotic levels (p = 0.026). No significant differences were detected between quantitative measurements and the patient outcome. CONCLUSIONS: Routine preoperative lumbar spine MRI can predict the patient outcome in a two-year follow up in patients with LSS surgery. Severe central stenosis and one-level central stenosis are predictors of good outcome. Preoperative finding of scoliosis may indicate worse functional ability.

Multiple psychological factors are associated with poorer functioning in a sample of community-dwelling knee osteoarthritis patients.

BACKGROUND: Knee osteoarthritis (OA) is the most common type of arthritis and imposes a heavy burden on individual welfare among elderly people. There is preliminary evidence that psychological factors play a role in functional ability and pain in knee OA patients, particularly with respect to the surgery outcome. Less is known about psychological factors among community-dwelling patients with knee OA. OBJECTIVES: We aimed to determine which psychological factors are associated with pain and functional ability among community-dwelling knee OA patients using a comprehensive set of psychological questionnaires. METHODS: In the cross-sectional baseline setting of a prospective, randomized controlled intervention study, 111 patients aged from 35 to 75 years with clinical symptoms and radiographic grading of knee OA were included. They completed a comprehensive set of psychological questionnaires, including measures of resources and coping, fear and catastrophizing, and distress. RESULTS: In cross-sectional comparisons, pain self-efficacy, fear of movement, pain catastrophizing, and elevated anxiety were associated with pain and a poorer functional ability. In logistic regression analysis, independent association was seen between pain self-efficacy and poorer functioning. Knee OA patients also reported elevated levels of anxiety. CONCLUSIONS: The results reveal that both pain self-efficacy and negatively charged emotion and expectations toward pain are important factors when dealing with knee OA patients. Failure to consider these will probably contribute to prolonged disability and further pain. The results call for the routine assessment of multiple psychological factors in knee OA.
