The course of acute low back pain: a community-based inception cohort study. Pain Rep 2024; 9:e1152. [PMID: 38606314 PMCID: PMC11008624 DOI: 10.1097/pr9.0000000000001152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 01/12/2024] [Accepted: 02/10/2024] [Indexed: 04/13/2024] Open
Abstract
Introduction Acute low back pain (LBP) is increasingly recognized for its potential recurrent nature and long-term implications. Objectives This community-based inception cohort study aimed to delineate trajectories of acute LBP over one year and investigate associated biopsychosocial variables. Methods One hundred seventy-six participants with acute LBP were monitored at 5 follow-up time points over 52 weeks. Pain trajectories were identified using a latent class linear mixed model, and their associations with baseline biopsychosocial factors were evaluated through multinomial logistic regression. Results Four distinct LBP trajectories were discerned: "mild/moderate fluctuating pain" (54.0%), "delayed recovery by week 52" (6.2%), "persistent moderate pain" (33.0%), and "moderate/severe fluctuating pain" (6.8%). Increased baseline pain intensity and history of LBP episodes were significantly linked with less favorable trajectories. Contrary to expectations, psychological variables like stress, anxiety, and depression did not significantly associate with unfavorable trajectories. Discussion This study underscores the heterogeneity of acute LBP's course over a year, challenging the conventionally benign perception of the condition. Recognizing these distinct trajectories might enable more tailored, effective clinical interventions for LBP patients. The small sample size of certain trajectories may influence the generalizability of the results. Conclusion Acute LBP can manifest in different trajectories, with nearly half of the participants experiencing less favorable trajectories. Baseline pain intensity and previous episodes of LBP emerged as key factors, whereas psychological variables had no discernible influence. Recognition of these trajectories may be necessary for improved patient management and targeted interventions.

Diagnostic and decision-making abilities of Swiss physiotherapists in a simulated direct access setting. Physiother Theory Pract 2023; 39:2336-2351. [PMID: 35645163 DOI: 10.1080/09593985.2022.2077269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 05/07/2022] [Accepted: 05/08/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Direct access to physiotherapy requires physiotherapists to recognize red flags and determine adequate management plans. PURPOSE Investigate Swiss physiotherapists' ability to diagnose and triage patients in a simulated direct access setting and whether their characteristics were associated with correct diagnoses and decision-making. METHODS We conducted a national online survey using a questionnaire containing 12 first-contact case scenarios. A linear mixed model estimated scores for correct diagnoses and management decisions, differences between musculoskeletal (MSK), non-critical medical (non-CrM), and critical medical (CrM) case scenarios, and the estimated effects of physiotherapists' characteristics. RESULTS The linear mixed model of data from 1492 participants estimated 55.0% correct diagnoses (62.7% for non-CrM, 61.7% for MSK, and 40.5% for CrM scenarios) and 71.2% correct management decisions (78.1% for non-CrM, 73.0% for MSK, and 62.3% for CrM scenarios). For correct diagnoses, the 'academic education/continuing education' variable showed significant estimated effects for the MSK and CrM scenarios, as did 'professional experience' for the non-CrM scenarios, and the '≥ 50% musculoskeletal patients in consultations' variable for all scenario groups. For correct management decisions, 'academic education/continuing education' variable showed significant estimated effects in CrM scenarios, as did 'professional experience' in non-CrM and CrM scenarios, and the '≥ 50% musculoskeletal patients in consultations' variable in MSK scenarios. CONCLUSION The estimated effects of physiotherapists' characteristics on correct diagnoses and management decisions showed substantial heterogeneity. Improving Swiss physiotherapists' screening abilities remains important. Further research is required to develop innovative educational concepts and improve training for screening for red flags.

Cervical musculoskeletal impairments and pressure pain sensitivity in office workers with headache. Musculoskelet Sci Pract 2023; 66:102816. [PMID: 37394322 DOI: 10.1016/j.msksp.2023.102816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/22/2023] [Accepted: 06/22/2023] [Indexed: 07/04/2023]
Abstract
BACKGROUND Office workers are specifically vulnerable to headache conditions. Neck pain is reported by almost 80% of patients with headaches. Associations between currently recommended tests to examine cervical musculoskeletal impairments, pressure pain sensitivity and self-reported variables in headache, are unknown. The aim of this study is to evaluate whether cervical musculoskeletal impairments and pressure pain sensitivity are associated with self-reported headache variables in office workers. METHODS This study reports a cross-sectional analysis using baseline data of a randomized controlled trial. Office workers with headache were included in this analysis. Multivariate associations, controlled for age, sex and neck pain, between cervical musculoskeletal variables (strength, endurance, range of motion, movement control) and pressure pain threshold (PPT) over the neck and self-reported headache variables, such as frequency, intensity, and the Headache-Impact-Test-6, were examined. RESULTS Eighty-eight office workers with a 4-week headache frequency of 4.8 (±5.1) days, a moderate average headache intensity (4.5 ± 2.1 on the NRS), and "some impact" (mean score: 53.7 ± 7.9) on the headache-impact-test-6, were included. Range of motion and PPT tested over the upper cervical spine were found to be most consistently associated with any headache variable. An adjusted R2 of 0.26 was found to explain headache intensity and the score on the Headache-Impact-Test-6 by several cervical musculoskeletal and PPT variables. DISCUSSION Cervical musculoskeletal impairments can explain, irrespective of coexisting neck pain, only little variability of the presence of headache in office workers. Neck pain is likely a symptom of the headache condition, and not a separate entity.

Change over time in functional capacity and self-perceived health status for patients with chronic musculoskeletal pain: a registry-based longitudinal study. Swiss Med Wkly 2023; 153:40083. [PMID: 37245120 DOI: 10.57187/smw.2023.40083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/29/2023] Open
Abstract
BACKGROUND AND AIMS Chronic musculoskeletal pain is a major public health problem worldwide. Both self-reported functional capacity and self-perceived health status are reduced in patients with chronic musculoskeletal pain. Previous studies mostly assessed functional capacity through self-reported questionnaires instead of objective measurements. The aim of this study, therefore, is to assess the amount of change over time and its clinical meaningfulness in functional capacity and self-perceived health status of patients with chronic musculoskeletal pain undergoing Bern Ambulatory Interprofessional Rehabilitation (BAI-Reha). METHODS The registry-based longitudinal cohort study with prospectively collected data from a rehabilitation programme took place in a real-life setting. Patients (n = 81) with chronic musculoskeletal pain took part in the BAI-Reha. The main outcomes were the six-minute-walk test (6MWT), the safe maximum floor-to-waist lift (SML) and the European Quality of Life and Health measure visual analogue scale (EQ VAS). Timepoints of measurement were at baseline and post-BAI-Reha (i.e., at 4 months). The quantity of interest was the adjusted time effect (point estimate, 95% confidence interval, and p-value for testing the null hypothesis of no change over time). Statistical significance (α = 0.05) and clinical meaningfulness of the mean value change over time were assessed using predefined thresholds (six-minute-walk test 50 m, SML 7 kg, and EQ VAS 10 points). RESULTS The linear mixed model analysis showed a statistically significant change over time for the six-minute-walk test (mean value change 56.08 m, 95% CI [36.13, 76.03]; p <0.001), SML (mean value change 3.92 kg, 95% CI [2.66, 5.19]; p <0.001), and EQ VAS (mean value change 9.58 points, 95% CI [4.87, 14.28]; p <0.001). Moreover, the improvement in the six-minute-walk test is clinically meaningful (mean value change 56.08 m) and almost clinically meaningful (mean value change 9.58 points) in the EQ VAS. CONCLUSION Patients walk further, lift more weight, and feel healthier after interprofessional rehabilitation when compared to baseline measurement. These findings confirm and add to previous results. IMPLICATIONS We encourage other providers of rehabilitation for patients with chronic musculoskeletal pain to measure functional capacity with objective outcome variables and to use self-reported outcome measures in addition to self-perceived health status. The well-established assessments used in this study are suitable for this purpose.

Influencing factors on instrumental activities of daily living functioning in people with mild cognitive disorder - a secondary investigation of cross-sectional data. BMC Geriatr 2022; 22:791. [PMID: 36217106 PMCID: PMC9552428 DOI: 10.1186/s12877-022-03476-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 09/23/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Finding a strategy to reduce the impact of cognitive decline on everyday functioning in persons suffering from cognitive impairment is a public health priority. Instrumental activities of daily living (IADL) are key to everyday functioning. Hence, it is essential to understand the influencing factors on IADL to develop specific interventions to improve everyday functioning in persons with mild cognitive disorder. Therefore, this study aimed to 1) explore different influencing factors on IADL functioning considering all domains of the International Classification of Functioning, disability, and health and 2) rank these factors. METHODS We performed a secondary analysis of a cohort including participants with amnestic mild cognitive impairment (a-MCI) or mild Alzheimer's Dementia (mild AD). The IADL functioning model was used as a starting point to estimate the effects of cognitive and physical function factors and personal and environmental factors on IADL functioning using multiple linear regression analysis, including subgroup analysis in persons with a-MCI. We used standardized coefficient estimates to relate the size of the predictor effects in the final model. RESULTS We included 105 participants (64 a-MCI, 41 mild AD); the mean age was 81.9 years (SD 4.9), with 70% females. Based on a multi-step approach and model fit, the final model included IADL functioning as the response variable and memory, attention, executive function, vision and hearing, mobility, balance, education, and social support as predictors. The final model explained 75% of the variability. The significant predictors in the model were mobility, balance, attention, and education, and were the predictors with the most considerable effects based on standardized coefficient estimates. The subgroup analysis, including only a-MCI participants, revealed a similar pattern. CONCLUSION Our results confirm that IADL functioning in people with mild cognitive disorder is influenced by cognitive and physical function and personal factors. The study provides further insight into understanding IADL functioning impairments in persons with mild impaired cognition and may be used to develop specific non-pharmacological interventions.

Lessons learned from a pilot implementation of physical activity recommendations in axial spondyloarthritis exercise group therapy. BMC Rheumatol 2022; 6:12. [PMID: 35034652 PMCID: PMC8762948 DOI: 10.1186/s41927-021-00233-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 10/05/2021] [Indexed: 01/20/2023] Open
Abstract
Background The Ankylosing Spondylitis Association of Switzerland (SVMB) aimed to implement physical activity recommendations (PAR) within their exercise groups (EGs). The PAR promote exercise in all fitness dimensions at the correct dose. To implement the PAR within EGs, they were translated into a new EG concept with five key activities: (a) training for supervising physiotherapists (PTs), (b) correctly dosed exercises in all fitness dimensions, (c) exercise counselling, (d) bi-annual fitness assessments, and (e) individual exercise training, in addition to EG. All these activities were realized in close coordination with SVMB management. Objectives To analyse the implementation success by evaluating adherence/fidelity, feasibility, and satisfaction at the patient, PTs, and organisational level. Methods The five key activities of the new EG concept were developed, executed, and assessed after 6 months. The primary outcomes for implementation success were adherence of patients to the recommended exercise behaviour, self-reported by electronic diary; fidelity of PTs to the new concept, self-reported by diary; SVMB organisational changes. Secondary outcomes were feasibility and satisfaction with the new EG concept at all three levels. The tertiary outcome, to evaluate the effectiveness of PAR, was patient fitness, assessed through fitness assessments. Results 30 patients with axSpA (ten women, mean age 58 ± 9 years) and four PTs (three women, mean age 46 ± 9 years) participated. The patients' self-reporting of adherence to the PAR was insufficient (43%), possibly due to technical problems with the electronic dairy. The PTs' fidelity to the new EG concept was satisfactory. On all levels, the new concept was generally perceived as feasible and useful for supporting personalised exercise.The frequency of exercise counselling and the fitness assessments was found by patients and PTs to be too high and rigid. Patients' cardiorespiratory fitness [ES 1.21 (95%CI 0.59, 1.89)] and core strength [ES 0.61 (95%CI 0.18, 1.06)] improved over the 6 months. Conclusions The pilot implementation of PAR showed acceptance and satisfaction to be sufficient, thus confirming the need for evidence-based EGs, provided by a patient organisation in order to support active PA behaviour. However, adaptations are necessary to increase its feasibility for nationwide implementation. Trial Registration: SNCTP, SNCTP000002880.

Effect of counselling during pulmonary rehabilitation on self-determined motivation to be physically active for people with chronic obstructive pulmonary disease: a pragmatic RCT. BMC Pulm Med 2021; 21:317. [PMID: 34641819 PMCID: PMC8506471 DOI: 10.1186/s12890-021-01685-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 09/23/2021] [Indexed: 11/16/2022] Open
Abstract
Background Counselling is considered to be a promising approach to increasing physical activity (PA) in people with chronic obstructive pulmonary disease (COPD). The aim of the current study was to investigate whether a PA counselling program for people with COPD, when embedded in a comprehensive outpatient pulmonary rehabilitation (PR) program, increased their daily PA. Methods A two-armed, single blind randomized controlled trial was conducted as a component of a 12-week outpatient pulmonary rehabilitation program. The participants randomized into the intervention group received five counselling sessions, based on the principles of motivational interviewing (MI), with a physiotherapist. The participants’ steps per day and other proxies of PA were measured using an accelerometer (SenseWear Pro®) at baseline, at the end of the PR program, and three months later. The group-by-time interaction effect was analyzed. Results Of the 43 participants,17 were allocated to the intervention group and 26 to the usual-care control group (mean age 67.9 ± 7.9; 21 (49%) males; mean FEV1 predicted 47.1 ± 18.6). No difference between groups was found for any measure of PA at any point in time. Conclusions In this study, counselling, based on MI, when embedded in a comprehensive PR program for people with COPD, showed no short-term or long-term effects on PA behavior. To investigate this potentially effective counselling intervention and to analyze the best method, timing and tailoring of an intervention embedded in a comprehensive outpatient PR program, further adequately powered research is needed.

Influence of weekday of admission and level of distress on length of hospital stay in patients with low back pain: a retrospective cohort study. BMC Musculoskelet Disord 2021; 22:656. [PMID: 34353298 PMCID: PMC8340547 DOI: 10.1186/s12891-021-04529-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Accepted: 07/16/2021] [Indexed: 11/22/2022] Open
Abstract
Background Low back pain (LBP) is often a complex problem requiring interdisciplinary management to address patients’ multidimensional needs. Providing inpatient care for patients with LBP in primary care hospitals is a challenge. In this setting, interdisciplinary LBP management is often unavailable during weekends. Delays in therapeutic procedures may result in a prolonged length of hospital stay (LoS). The impact of delays on LoS might be strongest in patients reporting high levels of psychological distress. Therefore, this study investigates the influence of weekday of admission and distress on LoS of inpatients with LBP. Methods This retrospective cohort study was conducted between 1 February 2019 and 31 January 2020. In part 1, a negative binomial model was fitted to LoS with weekday of admission as a predictor. In part 2, the same model included weekday of admission, distress level, and their interaction as covariates. Planned contrast was used in part 1 to estimate the difference in log-expected LoS between group 1 (admissions Friday/Saturday) and the reference group (admissions Sunday-Thursday). In part 2, the same contrast was used to estimate the corresponding difference in (per-unit) distress trends. Results We identified 173 patients with LBP. The mean LoS was 7.8 days (SD = 5.59). Patients admitted on Friday (mean LoS = 10.3) and Saturday (LoS = 10.6) had longer stays, but not those admitted on Sunday (LoS = 7.1). Analysis of the weekday effect and planned contrast showed that admission on Friday or Saturday was associated with a significant increase in LoS (log ratio = 0.42, 95% CI = 0.21 to 0.63). A total of 101 patients (58%) returned questionnaires, and complete data on distress were available from 86 patients (49%). According to the negative binomial model for LoS and the planned contrast, the distress effect on LoS was significantly influenced (difference in slopes = 0.816, 95% CI = 0.03 to 1.60) by dichotomic weekdays of admission (Friday/Saturday vs. Sunday-Thursday). Conclusions Delays in interdisciplinary LBP management over the weekend may prolong LoS. This may particularly affect patients reporting high levels of distress. Our study provides a platform to further explore whether interdisciplinary LBP management addressing patients’ multidimensional needs reduces LoS in primary care hospitals.

Abstract
Background:Falls in older people are frequent and have often severe health consequences. Reinforced by population ageing, they represent a substantial challenge for health care systems. Falls are often due to a combination of intrinsic and extrinsic risk factors. For these reasons, the Swiss League Against Rheumatism (SLAR) developed the multidimensional, home-based fall prevention programme ‘Sicher durch den Alltag’ (‘Safely Through Everyday Life’). The programme has been implemented nationwide since 2013 and is financed by selected health insurance companies. Trained physiotherapists (PTs) or occupational therapists (OTs) visit the senior at home for a 60-90 minutes session. They perform a detailed assessment of the senior’s individual risk of falling and subsequently eliminate identified environmental risk factors and provide tailored exercises. After 4 weeks, the PT/OT calls the senior to discuss further needs. The cost of the intervention is at 500 Swiss Francs (approximately 460 Euro) per senior.Objectives:Assess the effectiveness and cost-effectiveness of this fall prevention programme.Methods:A prospective, longitudinal observational study was performed. Baseline study data was assessed at the home visit, including the self-reported number of falls during a) the year and b) the month before the visit. The participants of the programme were monitored for one year after the home visit by bi-monthly telephone calls. Participants were asked to report the falls that they continuously documented in a diary. Questionnaires administered orally included the Falls Efficacy Scale-International (FES-I), a Quality of Life Questionnaire (EQ-5D-5L), and the amount of moderately intensive physical activity (PA).To compare the falls during the years before and after the home visit, the mean number of falls before the visit was calculated based on reported falls during a) the year and b) the month (multiplied by 12) before the visit. A 2:1 weighted mean from a) and b) was calculated, considering that retrospective reporting over one year or over one month may underestimate or overestimate, respectively, the number of falls. Statistical analysis fitted a GEE-Poisson-Modell (Generalized Estimating Equations) to the data for number of falls and a Linear Mixed Model (LMM) for fear of falling, quality of life and PA. Falls related health care spending in the years before and after the intervention were compared based on health insurance claims data.Results:Overall, 639 person-years of observation time were available for analysis. Participants were mainly female (59%) and had a mean age of 81.8+/- 5.2 years. On average, rate of falling decreased from 1.35 to 1.02 per person year (-23.9%), fear of falling decreased by -1.27 (95%CI -1.50, -1.05), quality of life improved by -0.88 (95%CI -1.09, -0.68), PA increased by 9.87 minutes per day (95%CI 5.65, 14.09). Health insurance claims data showed a 48.0% reduction (95%CI 30.5%, 61.0%) of medically treated falls. The average cost per prevented medically treated fall was estimated at 1317 Swiss Francs (approximately 1200 Euro) and the probability of the intervention being cost-saving at 47%.Conclusion:This low-threshold fall prevention programme was found to be very effective and cost-effective. Home visits by trained PTs or OTs contribute substantially to reduce falls in the elderly. The high cost-effectiveness is explained by a substantial reduction of severe falls.References:[1]Swiss Council for Accident Prevention BFU (2019); https://www.bfu.ch/de/die-bfu/medien/statistik-der-nichtberufsunfaelle-1.

The effect of age on the pressure pain threshold of asymptomatic ankles and knees in young individuals with haemophilia. Haemophilia 2021; 27:683-689. [PMID: 34015164 DOI: 10.1111/hae.14344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 04/24/2021] [Accepted: 05/03/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Despite adequate medical treatment, many young adults with haemophilia develop joint alterations-especially in ankles and knees. Undetected over years, subtle structural changes cause subclinical symptoms, before problems become obvious. To objectify these silent pressure pains, the pressure pain threshold (PPT) can be measured by algometry. AIM The aim was to investigate and compare the effect of age on PPTs in asymptomatic ankles and knees between boys and young adults with haemophilia and age-matched controls, in order to gain better knowledge about the alteration of the periarticular structures with increasing age. MATERIAL AND METHODS Nineteen persons with haemophilia (PwH; severe or moderate; 8-30 years) and 19 age-matched controls with 'healthy' ankles and knees were recruited. Asymptomatic joints with a Haemophilia Joint Health Score = 0 were included. The PPT was measured on four periarticular points per joint, and the data were analysed with a linear mixed model. RESULTS The PPT of the control group increased with age, whereas the PPT of the PwH decreased. The difference in age effect per year in kPa between PwH and controls was as follows: β [95%-CI]: -15.41 [-31.63; 0.79]. Although the result was not statistically significant (p = .08), a clear tendency was shown. CONCLUSION The results suggest that subclinical alterations in the periarticular structures of these joints may evolve unnoticed over time. However, further research is warranted to determine whether this observed trend is confirmed in a larger sample and at what age the PPT begins to decrease in PwH compared to controls.

Sensorimotor and body perception assessments of nonspecific chronic low back pain: a cross-sectional study. BMC Musculoskelet Disord 2021; 22:391. [PMID: 33902545 PMCID: PMC8077718 DOI: 10.1186/s12891-021-04269-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 04/15/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Low back pain (LBP) is one of the most common musculoskeletal disorders, causing significant personal and social burden. Current research is focused on the processes of the central nervous system (particularly the sensorimotor system) and body perception, with a view to developing new and more efficient ways to treat chronic low back pain (CLBP). Several clinical tests have been suggested that might have the ability to detect alterations in the sensorimotor system. These include back-photo assessment (BPA), two-point discrimination (TPD), and the movement control tests (MCT). The aim of this study was to determine whether the simple clinical tests of BPA, TPD or MCT are able to discriminate between nonspecific CLBP subjects with altered body perception and healthy controls. METHODS A cross-sectional study was conducted. At one point in time, 30 subjects with CLBP and 30 healthy controls were investigated through using BPA, TPD and MCT on the lower back. Correlations among the main covariates and odds ratios for group differences were calculated. RESULTS MCT showed an odds ratio for the presence of CLBP of 1.92, with a statistically significant p-value (0.049) and 95%CI. The TPD and BPA tests were unable to determine significant differences between the groups. CONCLUSIONS Of the three tests investigated, MCT was found to be the only suitable assessment to discriminate between nonspecific CLBP subjects and healthy controls. The MCT can be recommended as a simple clinical tool to detect alterations in the sensorimotor system of nonspecific CLBP subjects. This could facilitate the development of tailored management strategies for this challenging LBP subgroup. However, further research is necessary to elucidate the potential of all the tests to detect alterations in the sensorimotor system of CLBP subjects. TRIAL REGISTRATION No trial registration was needed as the study contains no intervention. The study was approved by the Swiss Ethics Commission of Northwest and Central Switzerland (EKNZ) reference number 2015-243.

[PMID: 32959189 PMCID: PMC7943491 DOI: 10.1007/s10067-020-05408-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 09/02/2020] [Accepted: 09/15/2020] [Indexed: 01/08/2023]
Abstract
OBJECTIVES To adapt the core strength endurance test battery (aCSE), previously used for testing athletes, to a target group of patients with axial spondylarthritis (axSpA), to evaluate its intra-tester reliability and its associations with disease-specific factors. METHODS A cross-sectional study was conducted at axSpA exercise therapy groups, including both axSpA patients and the physiotherapist group leaders (PTs). The aCSE was used to measure the isometric strength endurance of the ventral, lateral, and dorsal core muscle chains (measured in seconds), as well as to assess the disease-specific factors of functional status, self-reported pain, and perceived strength performance. The aCSE was repeated after 7-14 days to measure intra-tester reliability for the same rater (PT group leader). Reliability was calculated as an intra-class correlation coefficient (ICC) using a nested design. The associations between ventral, lateral, and dorsal strength endurance and the disease-specific factors were calculated using Pearson correlation coefficients. RESULTS Study participants were 13 PT group leaders and 62 axSpA patients. The latter were all capable of performing the aCSE, with the exception of one individual. A moderate to substantial intra-rater reliability (ICCs (95%CI)) was found for the ventral (0.54 (0.35, 0.74)), lateral (0.52 (0.33, 0.70)), and dorsal (0.71 (0.58, 0.86)) core muscle chains. None of the aCSE measures correlated with the disease-specific factors. CONCLUSION The aCSE was found to be a reliable test battery for assessing core strength endurance in axSpA patients. Interestingly, aCSE performance was not associated with any disease-specific factors. Key Points • The adapted core strength endurance test battery measures the isometric strength of the ventral, lateral and dorsal core muscle chains. • The adapted core strength endurance test battery showed a moderate to substantial intra-rater reliability for all three muscle chains tested in axSpA patients. • No correlations were found between the adapted core strength endurance test battery and the disease-specific factors of self-reported pain, functional status and perceived strength performance.

The Coping with and Caring for Infants with Special Needs intervention was associated with improved motor development in preterm infants. Acta Paediatr 2021; 110:1189-1200. [PMID: 33047325 PMCID: PMC7984220 DOI: 10.1111/apa.15619] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 10/06/2020] [Accepted: 10/08/2020] [Indexed: 12/12/2022]
Abstract
AIM We compared the impact of standard infant physiotherapy and the family-centred programme, Coping with and Caring for Infants with Special Needs (COPCA), in infants born before 32 weeks without significant brain lesions. METHODS This randomised controlled trial was carried out in patients' homes and outpatient settings in Switzerland between January 2016 and October 2019. We used data from the national SwissNeoNet register and an assessment battery that included infant and family outcomes and video analyses of therapy sessions. The Infant Motor Profile was the primary outcome instrument. RESULTS The COPCA group comprised six boys and two girls with a median gestational age of 27 weeks (range 25-30), and the standard care group comprised seven boys and one girl with a median gestational age of 29.5 weeks (range 26-31). COPCA participants improved significantly more between baseline and 18 months in the IMP variation (9.0 percentage points, 95% confidence interval: 0.3-17.5) and performance (12.0 percentage points, 95% confidence interval: 4.1-20.6) domains than standard care participants. COPCA coaching was positively associated with IMP scores at 18 months, but some standard care actions were negatively associated. CONCLUSION COPCA was associated with better motor outcome in infants born before 32 weeks than standard infant physiotherapy.

Cross-cultural adaptation and validation of the Amsterdam Instrumental Activities of Daily Living questionnaire short version German for Switzerland. Health Qual Life Outcomes 2020; 18:323. [PMID: 33008394 PMCID: PMC7530958 DOI: 10.1186/s12955-020-01576-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 09/23/2020] [Indexed: 01/18/2023] Open
Abstract
Background Instrumental Activities of Daily Living (IADL) limitations are associated with reduced health-related quality of life for people with mild cognitive impairment (MCI). For these people, the assessment of IADL is crucial to the diagnostic process, as well as for the evaluation of new interventions addressing MCI. The Amsterdam IADL Questionnaire Short Version (A-IADL-Q-SV) is an established assessment tool with good psychometric properties that has been shown to be robust to cultural differences in Western countries. The aims of this study were to: (1) cross-culturally adapt and validate the A-IADL-Q-SV for the German-speaking population of Switzerland; (2) investigate its cultural comparability; and (3) evaluate further psychometric properties. Methods The A-IADL-Q-SV German was pretested on clinicians and participants in a memory clinic setting. The psychometric properties and cultural comparability of the questionnaire were investigated in memory clinic settings including participants with MCI or mild dementia, as well as participants with normal cognition recruited from the community. Item response theory (IRT) was applied to investigate measurement invariance by means of differential item functioning to assess item bias. Additionally, the test–retest reliability on scale level, the construct validity through hypothesis testing and the discriminant validity of the A-IADL-Q-SV German were evaluated. Results Ninety-six informants of participants with normal cognition, MCI or mild dementia completed the A-IADL-Q-SV German. The basic assumptions for IRT scoring were met. No meaningful differential item functioning for culture was detected between the Swiss and Dutch reference samples. High test–retest reliability on scale level (ICC 0.93; 95% CI 0.9–0.96) was found. More than 75% of the observed correlations between the A-IADL-Q-SV German and clinical measures of cognition and functional status were found to be in the direction and of the magnitude hypothesized. The A-IADL-Q-SV German was shown to be able to discriminate between participants with normal cognition and MCI, as well as MCI and mild dementia. Conclusions The A-IADL-Q-SV German is a psychometrically robust measurement tool for a Swiss population with normal cognition, MCI and mild dementia. Thus, it provides a valuable tool to assess IADL functioning in clinical practices and research settings in Switzerland. Trial registration This study was registered retrospectively in July 2019 on ClinicalTrials.gov (NCT04012398).

Validation of the 7-item knee replacement patient education questionnaire (KR-PEQ-7), based on the 16-item knee osteoarthritis patient education questionnaire (KOPEQ). BMC Musculoskelet Disord 2020; 21:468. [PMID: 32677932 PMCID: PMC7367315 DOI: 10.1186/s12891-020-03476-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 07/05/2020] [Indexed: 11/30/2022] Open
Abstract
Background The aim of this study was to investigate the content validity including item reduction, construct validity and internal consistency of the existing 16-item Knee Osteoarthritis Patient Education Questionnaire. Former research had indicated that a reduction of items was necessary. Participants were patients with severe knee osteoarthritis who, prior to undergoing a knee replacement operation, participated routinely in a preoperative educational intervention. Methods A mixed method design was used. The first step was directed at the reduction in the number of items on the 16-item Knee Osteoarthritis Patient Education Questionnaire. Based on a priori hypotheses, this was followed by a cross-sectional validation study, performed to compare the resulting 7-item Knee Replacement Patient Education Questionnaire to a patient-testing Interview Protocol that was tailored to the same patient educational material. Additionally, the revised questionnaire was correlated with both the Short Test of Functional Health Literacy and the Mini-Mental State Examination score. Results A relatively high internal consistency was found for the 7-item Knee Replacement Patient Education Questionnaire, with a Cronbach’s alpha of 0.84 (SE: 0.036). Explanatory factor analysis showed no evidence against a one-factor model, with the first and second eigenvalues being 3.8 and 0.31, respectively. Bayesian Estimation of the correlation between the 7-item Knee Replacement Patient Education Questionnaire and the Interview Protocol was 0.78 (mode) (95% HPD 0.58–0.89). Conclusions The 7-item Knee Replacement Patient Education Questionnaire shows good psychometric properties and could provide valuable support to health professionals. It can provide valid feedback on how patients waiting for a knee replacement operation experience an applied patient education intervention. Further investigation is needed to assess the applicability of the 7-item Knee Replacement Patient Education Questionnaire to larger samples in different hospitals and countries.

Abstract
Poor riding performance may be due to medical issues with the horse or a variety of other factors, such as inadequate equipment or deficiencies in training. The physical fitness of the equestrian is one of the most unexplained factors of current research. The aim of this study is to investigate the association between the physical fitness of the equestrian and riding performance. 115 equestrians were assessed for physical fitness and riding performance. Seven components of physical fitness (balance, endurance, flexibility, reaction, speed, strength, symmetry) were measured by a physiotherapist using equestrian-specific tests. Based on a video-recorded riding test, individual riding performance was rated by two equestrian judges. The riding test included the horse and rider performing a walk, sitting trot, rising trot and canter in both directions. A linear model for riding performance, including the domains of physical fitness and potential confounders (body-mass-index, riding experience, hours of riding per week, and test-motivation), was fitted to the data. Inter-rater reliability of the judges was investigated by calculating the intraclass correlation coefficient (ICC). Endurance, reaction and strength were positively associated with riding performance, whereas flexibility had a negative association. The final model could explain 16.7% of the variance in riding performance. The effects of endurance and strength were significant (P<0.05), but not that of reaction. No association with riding performance was found for the components of balance, speed and symmetry. The inter-rater reliability of judges was confirmed to be ‘good’ to ‘excellent’ (ICC=0.9, 95% confidence interval: 0.86-0.93). Findings suggest that physical fitness is positively associated with riding performance. Fitness-training for equestrians should be included in current training concepts. Future research should investigate whether similar associations exist for junior and elite athletes.

Abstract
Abstract
Objectives
Physiotherapy is recommended in the management of people with axial Spondyloarthritis (axSpA), with new insights into its preferred content and dosage evolving. This study aimed to describe the use and preferences regarding individual and group physiotherapy among people with axSpA.
Methods
A cross-sectional survey was conducted among people with axSpA living in the Netherlands (NL) and Switzerland (CH).
Results
713 people with axSpA participated (56.7% male, median age 55 years, median ASAS-Hi-score 4.2). Response rates were 45% (n = 206) in NL and 29% in CH (n = 507). 83.3% of participants were or had been using physiotherapy. Individual therapy only was or had been used by 36.7%, a combination of individual plus land- and water-based group therapy was or had been used by 29.1% and group therapy only by 5.3%. Only less than half participants attending individual therapy reported active therapy (like aerobic, muscle strength, flexibility exercises). Although the majority (75.9%) was not aware of the increased cardiovascular risk, participants showed an interest in cardiovascular training, either individually or in a supervised setting. If supervised, a majority, in CH (75.0%) more than in NL (55.7%), prefers supervision by a specialized physiotherapist.
Conclusion
The majority of people with axSpA uses or used physiotherapy, more often in an individual than in a group setting. The content of individual therapy should be more active; in both therapy settings aerobic exercises should be promoted. Especially, enabling people with axSpA to perform exercises independently would meet their needs and might enhance their daily physical activity.

Concurrent validity and reliability of a mobile tracking technology to measure angular and linear movements of the neck. J Biomech 2019; 96:109340. [PMID: 31558310 DOI: 10.1016/j.jbiomech.2019.109340] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 09/10/2019] [Accepted: 09/11/2019] [Indexed: 10/26/2022]
Abstract
The neck can be moved in six degrees of freedom. Current 3D-optoelectronic motion-capture systems capable of measuring these movements are inappropriate for use in clinical practice because they are stationary, expensive and time-consuming. We therefore developed a less complex 3D-tracking technology based on Steam®VR to measure six degrees of freedom in a clinical setting. The aim of this study was to assess the validity and reliability of this system. The developed prototype consists of two infrared-emitting lighthouses and sensors, mounted on the participant's helmet and trunk belt, to detect the orientation of the head and trunk. The system was evaluated by means of an infrared light-reflecting marker tracking system. Twenty healthy participants, equipped with these sensors and markers, performed thirteen neck movement tasks. Linear and angular movements were measured. These tasks were repeated after six to eight days to assess test-retest reliability. Concurrent validity was assessed by the root mean square error, and reliability with generalizability theory. With an average root mean square error between 1.2 and 2.0° in angular and 0.4-0.5 cm in linear movements, the prototype was shown to precisely track these movements. Reliability of the prototype and the reference system was comparable for all tasks. A high contribution of participant's variability to the observed variance was generally detected, with the exception of joint repositioning error and upper cervical flexion. The reliability was task-specific and did not differ between the systems. The prototype system was shown to be valid, although the reliability of the repositioning and upper cervical flexion tests needs to be reconsidered.

Abstract
INTRODUCTION Lumbar movement variability during heavy, repetitive work may be a protective mechanism to diminish the progression of lumbar disorders and maintain neuromuscular functional integrity. The effect of neuromuscular exercise (NME) on the variability of lumbar movement is still to be determined. METHODS A randomised controlled trial was conducted on a population of nursing personnel with subacute LBP. Following randomization, the NME group participants completed an NME program of six months duration. The participants in the control group only attended the assessment sessions. The outcomes were assessed at: baseline; after six months intervention; 12 months. The primary outcome was lumbar movement variability based on angular displacement and velocity. RESULTS A positive treatment effect on lumbar movement variability was seen after six months of NME intervention. Angular displacement improved, and angular velocity remained constant. At the 12-month follow up, however, the effect faded in the NME group. Lumbar movement variability worsened in the control group over all time periods. CONCLUSION NME may improve lumbar movement variability in the short term and may indicate improved neuromuscular functional integrity. The design of an optimal NME program to achieve long-term improvement in lumbar movement variability is a subject worthy of further research.

Abstract
BACKGROUND Activities of daily living (ADL) are crucial for children because they enable them to participate in everyday life. For the evaluation of children`s ADL performance, health professionals such as occupational therapists use standardized ADL assessments. To implement assessments into practice it is important that the score generated from an assessment can be viewed as a unidimensional measure. AIM To investigate the factor structure of the German Pediatric Evaluation of Disability Inventory (PEDI-G) in a sample of typically developing children and children with an impairment. MATERIAL AND METHODS An exploratory factor analysis (EFA) with factor rotation was performed to assess the factor structure for the PEDI-G domains (self-care, mobility and social function) of the Functional Skills Scale and the Caregiver Assistance Scale. RESULTS 262 children (118 (45%) girls and 144 (55%) boys) participated in this study. Their mean age (SD) was 4 years (SD 1.91). Results suggest that the PEDI domains of the Functional Skills Scale and the Caregivers Assistance Scale can be used as unidimensional measures to evaluate child`s ability to perform activities of daily living. CONCLUSION The results of this study support the use of the PEDI-G for research and practice in Austria, Germany and Switzerland.

Abstract
Objectives A reliable detection of bony landmarks of the spine is necessary in order to determine rigid bodies and to reduce the variability of marker placement in a movement laboratory setting. In a first study on the thoracic and lumbar spine, we demonstrated that placing markers on their relative positions between two major landmarks was superior to palpation of specific bony landmarks. The aims of this study were to examine the intra-rater reliability when palpating for spinous processes (SPs) of the second (C2) and seventh cervical vertebrae (C7), to determine the distances between C2 and C7 and the relative position of C7 along the length between C2 and the posterior superior iliac spine (PSIS) level. Results The intra-rater reliability in determining the distance between C2 and C7 was found to be substantial, with an intra-rater reliability of 0.75 (95% confidence limits 0.55–0.99) and a standard error of the measurement of 0.34 cm. The relative distance of C7 along the total C2–PSIS length was estimated to be 11.5%. The determination of the relative positions of spinal landmarks through measurement is considered superior to their palpation, because it relies on a reproducible and comparable definition of rigid bodies.

Abstract
Multicomponent interventions (MCT) combine physical exercises and cognitive training and seem to be most effective in improving cognition in elderly people. However, literature is inconclusive if MCTs are superior to active comparison interventions, if delivery modes matter, and if people can transfer achieved effects to instrumental activities of daily living (IADL). This network meta-analysis aimed to a) identify MCTs that were effective on physical capacity and/or cognitive function and able to transfer these effects into IADL in elderly people with normal cognition (NC) and mild cognitive impairment (MCI); b) provide a rating on the best interventions per outcome; c) evaluate MCTs' mode of delivery. Eligible studies were randomized controlled trials comparing MCTs to active comparison or no treatments. Six studies in participants with MCI (n = 1088) and eleven studies in participants with NC (n = 670) were included. Five effective MCTs that were superior to physical exercises or cognitive training alone in improving physical capacity and/or cognitive function were detected, however none of these MCTs improved IADL. In people with NC MCTs performed separately or simultaneously were effective. However, in people with MCI MCTs performed separately were more effective. A framework needs to be developed to better understand the mediating effects of physical capacity and cognitive function on IADL and to design MCTs that effectively improve IADL.

Abstract
BACKGROUND In the management of chronic low back pain (LBP), identifying and managing more patients who are at high risk and who have psychological barriers to recovery is important yet difficult. OBJECTIVE The objective of this study was to test physical therapists' ability to allocate patients into risk stratification groups, test correlations between therapists' assessments of psychological factors and patient questionnaires, and explore relationships between psychological factors and therapists' self-reported competence to manage patients with chronic LBP. DESIGN This was a pragmatic, observational study. METHODS Patients completed the STarT Back Tool (SBT, for risk stratification), the Four-Dimensional Symptom Questionnaire (distress, depression, anxiety), and the Tampa Scale of Kinesiophobia (kinesiophobia) prior to the intake session. After this session, physical therapists estimated patient prognostic risk using the 3 SBT categories and rated patient psychological factors using a 0-to-10 scale. Finally, therapists reported their self-reported competence to manage the patient. Intraclass and Spearman rank correlations tested correlations between therapists' intuitive assessments and patient questionnaires. A linear-mixed model explored relationships between psychological factors and therapists' self-reported competence. RESULTS Forty-nine patients were managed by 20 therapists. Therapists accurately estimated SBT risk allocation in only 41% of patients. Correlations between therapist perceptions and patient questionnaires were moderate for distress (r = 0.602) and fair for depression (r = 0.304) and anxiety (r = 0.327). There was no correlation for kinesiophobia (r = -0.007). Patient distress was identified as a negative predictor of therapists' self-reported competence. LIMITATIONS This was a cross-sectional study, conducted in only 1 center. CONCLUSIONS Physical therapists were not very accurate at allocating patients into risk stratification groups or identifying psychological factors. Therapists' self-reported competence in managing patients was lowest when patients reported higher distress.

Abstract
The Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) is a questionnaire that is frequently used to measure the treatment orientation of physiotherapists and other healthcare providers toward low back pain (LBP). Previous validation studies of the PABS-PT have reported consistently that exploratory factor analysis (EFA) yielded a two-factor model with the factors "biomedical" and "biopsychosocial." However, there remain concerns regarding the composition of these two factors and the internal consistency of the "biopsychosocial" factor. The objective of this study was to replicate the previous validation study on the German PABS-PT. EFA was implemented to reexamine the underlying structure of the scale, and confirmatory factor analysis (CFA) was used to test the fit of the hypothesized two-factor model. Results of the initial validation study were not replicated. EFA indicated that a two-factor solution is an inadequate representation of the PABS-PT data, and CFA showed insufficient fit of the hypothesized two-factor model to the PABS-PT data. Our results indicate a need for caution when using the PABS-PT to measure physiotherapists' orientation toward LBP, particularly in measuring the magnitude of a biopsychosocial orientation.

Abstract
BACKGROUND Lateral gliding cervical spine mobilisation is shown to improve shoulder pain, disability and function. However, despite common clinical-use, no study reports the effect of unilateral anterior-posterior (A-P) cervical mobilisation on shoulder pain and function, and particularly in patients after arthroscopic shoulder surgery. OBJECTIVE Examine the immediate effect of single-level Grade III cervical unilateral A-P mobilisation on shoulder pain, flexion and abduction range of motion (ROM) and external rotator strength compared to placebo cervical unilateral A-P light touch pressure. METHODS Single session intervention with a crossover design in 32 (15 women) postoperative arthroscopic shoulder patients. RESULTS Immediate and superior treatment effects were shown for A-P cervical mobilisation in improving flexion ROM, isometric strength of external rotation, and pain intensity during flexion (all p< 0.05) when compared to the placebo. However, effects may not be considered clinically meaningful. CONCLUSION Unilateral A-P mobilisation applied to the cervical spine shows a tendency toward positively influencing post-arthroscopy shoulder pain and function. Further study examining cervical mobilisations directed in different planes to influence shoulder motion appear warranted.

Abstract
Background: After total knee arthroplasty (TKA) efficient control and reduction of postoperative edema is of great importance. Aim: The aim of this pilot study (EKNZ 2014 – 225 DRKS00006271) was to investigate the effectiveness of multi-layer compression therapy (MLCT) to reduce edema in the early period after surgery compared to the standard treatment with Cool Pack. Methods: In this randomized controlled pilot trial, sixteen patients after TKA were randomized into an intervention group (IG) or a control group (CG). Circumferential measurements were used to assess edema. Secondary outcomes were range of motion (ROM), pain (numeric rating scale, NRS) and function as measured with the fast Self Paced Walking Test (fSPWT). Results: Clinically relevant differences in edema reduction between the two groups were found in the early postoperative period and at the six weeks follow up. Six days postoperatively the group time interaction (IE) in favor of the IG were −3.8 cm (95 % CI: −5.1; −2.4) when measured 10 cm proximal to the joint space and −2.7 cm (CI: −4.1; −1.3) when measured 5 cm proximally. We further observed differences in secondary outcomes in favor of the CG. Six days postoperatively the IE for knee flexion was –8.3 ° (CI: −22.0; 5.4) and for the fSPWT it was 12.8 seconds (CI: −16.4; 41.3). Six weeks postoperatively these differences diminished. Conclusions: The findings suggest that MLCT could be an alternative treatment to reduce postoperative edema in patients after total knee arthroplasty. Eventually possible negative effects on early knee flexion and function must be considered.

Abstract
BACKGROUND Physical activity promotion in people with Chronic Obstructive Pulmonary Disease (COPD) is focus of research and public health. Patient-centred interventions like counselling are promising approaches to help patients reducing sedentary behaviour. Aim of the present study is to investigate if a physical activity counselling program during pulmonary rehabilitation increases physical activity level in daily life in people with COPD. METHODS A two-armed, single blind randomised controlled trial including 56 people with COPD will be conducted in an outpatient pulmonary rehabilitation. Patients will participate in a 12-week-rehabilitation program; individuals randomized to the interventional group will additionally participate in five counselling sessions with a physiotherapist, based on the principles of motivational interviewing. The participants' physical activity level will be measured using an accelerometer (SenseWear Pro®) before, directly and 3 months after pulmonary rehabilitation. Semi-structured interviews will be conducted to learn more about barriers and facilitators regarding daily physical activity. DISCUSSION If the strategy successfully improves the physical activity level in people with COPD, counselling might be implemented in pulmonary rehabilitation.

Abstract
Background Hip joint complaints are a problem associated with increasing age and impair the mobility of a large section of the elderly population. Reliable and valid tests are necessary for a thorough investigation of a joint. A fundamental function of the hip joint is movement control and a test of this function forms a part of the standard examination. Until now there have been few scientific studies which specifically investigate the reliability of measurement tests of movement control of the hip joint. The aim of this study was to examine the intratester and intertester reliability of the movement control tests of the hip joint which are in use in current clinical practice. Methods Sixteen participants with hip joint complaints and 14 without hip joint impairment were recruited. All participants performed five active movement control tests for the hip joint and were video filmed whilst performing these tests. These films formed the basis for the evaluation and were assessed by two independent physiotherapists. For the intertester and intratester reliability calculations specially set weighted kappa values and the calculated percentages were used. Results The intertester reliability of the five examined movement control tests of the hip joint showed good to almost perfect values (weighted kappa (wk) = 0.56–0.87). The intratester reliability of the more experienced evaluator A was better in regards to the less experienced evaluator B (average wk = 0.62 vs 0.38). Conclusion The visual evaluation of movement control tests of the hip joint is especially reliable when carried out by an experienced evaluator. 4 out of 5 tests also showed good results for intertester reliability and support their use in clinical practice.

Correlation between lumbar dysfunction and fat infiltration in lumbar multifidus muscles in patients with low back pain. BMC Musculoskelet Disord 2017; 18:12. [PMID: 28068962 PMCID: PMC5223418 DOI: 10.1186/s12891-016-1376-1] [Citation(s) in RCA: 73] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Accepted: 12/21/2016] [Indexed: 12/17/2022] Open
Abstract
Background Lumbar multifidus muscles (LMM) are important for spinal motion and stability. Low back pain (LBP) is often associated with fat infiltration in LMM. An increasing fat infiltration of LMM may lead to lumbar dysfunction. The purpose of this study was to investigate whether there is a correlation between the severity of lumbar dysfunction and the severity of fat infiltration of LMM. Methods In a cross-sectional study, 42 patients with acute or chronic LBP were recruited. Their MRI findings were visually rated and graded using three criteria for fat accumulation in LMM: Grade 0 (0–10%), Grade 1 (10–50%) and Grade 2 (>50%). Lumbar sagittal range of motion, dynamic upright and seated posture control, sagittal movement control, body awareness and self-assessed functional disability were measured to determine the patients’ low back dysfunction. Results The main result of this study was that increased severity of fat infiltration in the lumbar multifidus muscles correlated significantly with decreased range of motion of lumbar flexion (p = 0.032). No significant correlation was found between the severity of fat infiltration in LMM and impaired movement control, posture control, body awareness or self-assessed functional disability. Conclusion This is the first study investigating the relationship between the severity of fat infiltration in LMM and the severity of lumbar dysfunction. The results of this study will contribute to the understanding of the mechanisms leading to fat infiltration of LMM and its relation to spinal function. Further studies should investigate whether specific treatment strategies are effective in reducing or preventing fat infiltration of LMM.

Abstract
OBJECTIVE The aim of this study was to develop a generic instrument for the use of patients, named the Knee Osteoarthrtis Patient Education Questionnaire (KOPEQ), to assess the validity of a preoperative educational intervention and to make a preliminary test of its psychometric properties. METHODS A patient-reported outcome instrument was designed, using the conceptual framework of Wilson and Cleary as a methodological guide. Likert items with a five-point scale were chosen for the scoring option. The feasibility and interpretability of administering the KOPEQ was tested through conducting interviews with targeted patients. Items of the KOPEQ were linked to the International Classification of Functioning, Disability and Health (ICF). Psychometric testing contained internal consistency for reliability, and factor analysis for validity properties. RESULTS A final list of 16 items was derived and linked to the ICF. Targeted patients confirmed in interviews, that all 16 questions were highly understandable and that the length of the questionnaire was feasible and acceptable. There was a good internal consistency for the 16-item KOPEQ with a Cronbach's alpha of 0.83 (95% confidence interval 0.71-0.94). Sixty-one percent of the variance was explained by a four-factor model and the factors were named "didactics", "addressability", "empowerment" and "theory". Results of a factor analysis provided a loading of the separate items between 0.469 and 0.958. CONCLUSIONS The KOPEQ can help to provide health professionals with reliable feedback on how patients assessed the applied patient education intervention. Interviews with patients and a factor analysis revealed new and important insight.

Abstract
INTRODUCTION Pain intensity attenuates muscular activity, proprioception, and tactile acuity, with consequent changes of joint kinematics. People suffering from low back pain (LBP) frequently show movement control impairments of the lumbar spine in sagittal plane. This cross-sectional, observational study investigated if the intensity of LBP attenuates lumbar movement control. The hypothesis was that lumbar movement control becomes more limited with increased pain intensity. METHODS The effect of LBP intensity, measured with a numeric rating scale (NRS), on lumbar movement control was tested using three movement control tests. The lumbar range of motion (ROM), the ratio of lumbar and hip ROM as indicators of direction specific movement control, and the recurrence and determinism of repetitive lumbar movement patterns were assessed in ninety-four persons suffering from LBP of different intensity and measured with an inertial measurement unit system. Generalized linear models were fitted for each outcome. RESULTS Lumbar ROM (+ 0.03°, p = 0.24) and ratio of lumbar and hip ROM (0.01, p = 0.84) were unaffected by LBP intensity. Each one point increase on the NRS resulted in a decrease of recurrence and determinism of lumbar movement patterns (-3.11 to -0.06, p ⩽ 0.05). DISCUSSION Our results indicate changes in movement control in people suffering from LBP. Whether decreased recurrence and determinism of lumbar movement patterns are intensifiers of LBP intensity or a consequence thereof should be addressed in a future prospective study.

Abstract
BACKGROUND The contemporary occupational therapy literature suggests that different quality criteria exist for setting goals in occupational therapy: a focus on occupation; a link to the International Classification of Functioning, Disability, and Health (ICF); and adherence to the SMART recommendations, which advises goals to be specific, measurable, agreed, realistic, and timed. AIM To identify the extent to which Swiss occupational therapists (OTs) adhere to the criteria cited above. MATERIAL A total of 1,129 goals formulated with the Goal Attainment Scale (GAS) collected in 2008. RESULTS In slightly more than half the investigated cases at least one goal addressed an aspect of occupation. Nearly two-thirds of the goals related to the ICF component "activity and participation". Nearly 90% of the goals were specific, measurable, and/or realistic. CONCLUSIONS Goals mirror, to some extent, what is done in everyday practice. Several influences on goal formulations of OTs were identified, including the practice models traditionally used in different specialist fields; the cultural contexts in which OTs were trained; and the legal framework that obliges OTs to formulate their goals in a certain way in order to obtain funding for their services. SIGNIFICANCE Based on these results evidence-based products have been developed (a further education course; written recommendations for practice).

Effect of preoperative neuromuscular training (NEMEX-TJR) on functional outcome after total knee replacement: an assessor-blinded randomized controlled trial. BMC Musculoskelet Disord 2015; 16:101.

Abstract
Background Improving functional status preoperatively through exercise may improve postoperative outcome. Previous knowledge on preoperative exercise in knee osteoarthritis is insufficient. The aim of the study was to compare the difference in change between groups in lower extremity function from baseline to 3 months after Total Knee Replacement (TKR) following a neuromuscular exercise programme (NEMEX-TJR) plus a knee school educational package (KS) or KS alone. Methods 45 patients (55–83 years, 53% male, waiting for TKR) were randomized to receive a minimum of 8 sessions of NEMEXTJR plus 3 sessions of KS or 3 sessions of KS alone. Function was assessed with the Chair Stand Test (CST, primary endpoint) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales focusing on daily living function (ADL) and pain (secondary endpoints). Assessments were performed immediately before and after the intervention, and at 6 weeks, 3 months and 12 months after surgery by a physiotherapist, blinded to group allocation. Results After intervention before surgery we observed a small improvement for primary and secondary endpoints in both groups, which did not differ significantly between groups: comparing the exercise to the control group the treatment effect for the CST was −1.5 seconds (95% CI: −5.3, 2.2), for KOOS ADL and KOOS pain the treatment effect was 1.3 points (−10.1, 12.8) and −2.3 (−12.4, 7.9) respectively. At 3 months after surgery we observed a small improvement in the primary endpoint in the control group and a significant improvement in the secondary endpoints in both exercise and control groups, which did not differ significantly between groups: comparing the exercise group to the control group the treatment effect in the CST was 2.0 seconds (−1.8, 5.8), for KOOS ADL and KOOS pain the treatment effect was −4.9 points (−16.3, 6.5) and −3.3 points (−13.5, 6.8) respectively. Conclusions A median (IQR) of 10 (8, 14) exercise sessions before surgery showed an additional small but non-significant improvement in all functional assessments compared to patient education alone. These benefits were not sustained after TKR. Our trial doesn’t give a conclusive answer to whether additional preoperative exercise on postoperative functional outcomes is beneficial.

Abstract
BACKGROUND One important goal of paediatric occupational therapy services is to improve activities of daily living (ADL) abilities of children. In order to plan and evaluate the effectiveness of targeted interventions, valid assessments are critically needed. The Assessment of Motor and Process Skills (AMPS) is an internationally standardized assessment of ADL performance that has not been validated for use with children in Middle Europe. AIM To evaluate for (i) significant differences in mean ADL motor and mean ADL process ability measures among children from Middle Europe compared with children from North America, UK/Republic of Ireland, Nordic countries, Western Europe, Australia/New Zealand and Asia; and (ii) meaningful differences between the international age-normative means of the AMPS and those for children from Middle Europe. METHOD We analysed data of children across world regions extracted from the international AMPS database using many-facet Rasch and two-way anova analyses and by estimating contrasts to evaluate for significant group differences. RESULTS anova analyses of data for 11 189 children ages 2-15 revealed significant effects for mean ADL motor and ADL process ability by region [F ≥ 15.32, d.f. = (6, 11 091), MSE ≥ 0.20, P < 0.001, ή(2) ≥ 0.008], and age [F ≥ 253.47, d.f. = (13, 11 091), MSE ≥ 0.20, P < 0.001, ή(2) ≥ 0.229], and a significant interaction effect for mean ADL process ability [F = 1.48, d.f. = (78, 11 091), P = 0.004, ή(2) = 0.010]. Out of 168 estimated contrasts between Middle Europe and the other world regions for mean ADL motor and ADL process ability, seven were statistically significant (4.17%), but none exceeded ±1SE from the international means. CONCLUSION The AMPS remains free of relevant differences in mean ADL ability measures between Middle Europe and other world regions, indicating that the international age-normative mean values are likely to be applicable to children from Middle Europe. The AMPS can be used internationally to evaluate ADL performance in children and to determine if the child is eligible for occupational therapy services.

Abstract
OBJECTIVE To validate clinical vignettes as a measure of physiotherapists' activity and work recommendations given to patients with non-specific low back pain. DESIGN Validation study comparing two methods for measuring aspects of health providers' clinical management: Clinical vignettes and unannounced visits of standardized patients (the gold standard). SETTING Outpatient physiotherapy clinics. SUBJECTS Physiotherapists (N = 59) who consented to see unannounced standardized patients in their clinical practice. MAIN MEASURES Clinical vignettes were used to initially measure physiotherapists' self-reported activity and work recommendations. Subsequently, actors performing as standardized patients visited physiotherapists in their clinical practice and rated the advice given by the physiotherapist regarding activity and work. A total of 23 standardized patients were randomly scheduled to physiotherapists. Physiotherapists were blinded towards the standardized patients. To test whether standardized patients were detected, physiotherapists reported if they suspected that they had treated an actor. RESULTS The 23 standardized patients visited 22 different physiotherapists. Physiotherapists detected 12 out of 23 unannounced standardized patients (detection rate: 52%). The estimated agreement between the two measures was poor, for both activity and work recommendations (weighted kappa coefficients: 0.29 resp. -0.21). CONCLUSION The poor concordance between clinical vignettes and standardized patients indicates the potentially limited validity of clinical vignettes as a measure of health providers' activity and work recommendations in low back pain practice.

Abstract
Association of low back pain and standing postural control (PC) deficits are reported inconsistently. Demands on PC adaptation strategies are increased by restraining the input of visual or somatosensory senses. The objectives of the current study are, to investigate whether PC adaptations of the spine, hip and the centre of pressure (COP) differ between patients reporting non-specific low back pain (NSLBP) and asymptomatic controls. The PC adaption strategies of the thoracic and lumbar spine, the hip and the COP were measured in fifty-seven NSLBP patients and 22 asymptomatic controls. We tested three "feet together" conditions with increasing demands on PC strategies, using inertial measurement units (IMUs) on the spine and a Wii balance board for centre of pressure (COP) parameters. The differences between NSLBP patients and controls were most apparent when the participants were blindfolded, but remaining on a firm surface. While NSLBP patients had larger thoracic and lumbar spine mean absolute deviations of position (MADpos) in the frontal plane, the same parameters decreased in control subjects (relative change (RC): 0.23, 95% confidence interval: 0.03 to 0.45 and 0.03 to 0.48). The Mean absolute deviation of velocity (MADvel) of the thoracic spine in the frontal plane showed a similar and significant effect (RC: 0.12 95% CI: 0.01 to 0.25). Gender, age and pain during the measurements affected some parameters significantly. PC adaptions differ between NSLBP patients and asymptomatic controls. The differences are most apparent for the thoracic and lumbar parameters of MADpos, in the frontal plane and while the visual condition was removed.

Abstract
BACKGROUND Movement control impairment reduces active control of movement. Patients with this might form an important subgroup among patients with mechanical cervical pain. Diagnosis is based on the observation of active movement tests. Although widely used clinically, few studies have been performed to determine the reliability of a test battery. The aim of this study was to determine the inter-tester reliability of movement control impairment [MCI] tests on the cervical spine. METHODS Forty-five subjects (31 patients with neck pain, 14 healthy controls) were videotaped while performing a standardized test battery consisting of 13 tests of active movement control. Using observation, two experienced physiotherapists independently rated test performances as correct or incorrect. One of them was blinded to all other patient information and both to each other. Kappa coefficients and 95% confidence intervals [CI] for inter-tester results were calculated. RESULTS The kappa values for inter-tester reliability ranged in from 0.47-1.0 of the 13 tests, 2 demonstrated perfect reliability (k = 1.0), 4 excellent (k 0.81-0.99), 6 substantial (k 0.61-0.8) and 1 good (k 0.41-0.6). CONCLUSIONS The physiotherapists were able reliably rate the majority the tests in this series of motor control tasks. There have been studies performed describing the assessment and treatment of movement control impairment problems and low back pain. However, no study has involved the assessment of the cervical dysfunction subgroup. This study presents a reliable test battery, for clinical use, to perform more specific examination of this subgroup.

Abstract
ABSTRACT Activities of daily living (ADL) of children are widely assessed with the Pediatric Evaluation Disability Inventory (PEDI). This study examined test-retest and inter-rater reliability of the German PEDI (PEDI-G). During the adaptation of the PEDI nine items were added. In total, 117 parents of 53 children without and 64 children with a diagnosed physical disability from Austria, Germany, and Switzerland participated. Reliability was examined by intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable difference (SDD) for the Functional Skill Scale with and without added items and the Caregiver Assistance Scale. Cohen`s Kappa was used to calculate the reliability of the Modification Scale. All ICC's for test-retest and inter-rater reliability were above 0.75, indicating good to very good reliability. The SDD varied from 0.83-5.58 across PEDI domains and scales. For the Modification Scale, Cohen's weighted kappa varied from 0.25 to 1.00 indicating sufficient reliability for some but not all items. Our findings indicate that the Functional Skill Scale and the Caregiver Assistance Scale of the PEDI-G are reliable scales that can be used to evaluate ADLs of children with and without physical disability.

Abstract
Background Head-eye movement control deficit is an identified problem in patients with chronic neck pain, particularly in cases of whiplash associated disorders (WAD). To date, there is no evidence concerning the reliability and validity of visually assessed active head-eye movement control tests. Therefore, the objectives of the present cross-sectional study were, a) to develop a test battery; and b) to investigate inter-observer reliability and discriminative validity in patients with chronic neck pain compared to healthy controls. Methods The study was conducted at two physiotherapy clinics in Switzerland. Ethics Committee approval was obtained. Ten active head-eye coordination tests, on 23 patients with chronic neck pain and associated symptoms and 19 healthy controls, were videotaped. The tests included eye movements in the neutral head position and 45° relative neck rotation, gaze stability and sequential head-eye movements. All tests were performed in the sitting and standing positions. Two blinded physiotherapists independently rated the randomized videos. Performance was rated as "negative", "moderately positive" or "clearly positive". Weighted kappa (wK) and 95% confidence intervals (CI) were calculated to investigate inter-observer reliability. Good reliability was defined as wK >0.5 with a lower boundary of 95% CI >0.2. Odds ratios (to define cut-off points) and the distribution of the classificator, numbers of positive tests, were calculated. Results Three out of ten tests showed "excellent" (wK 0.82 to 0.86), five out of ten tests showed "substantial" (wK 0.69 to 0.79) and two out of ten tests showed "moderate" (wK 0.54 to 0.59) reliability. Results were comparable in the sitting and standing positions. On average, three out of five tests were rated positive in patients and one out of five tests was rated positive in healthy controls. An odds ratio of 13.3 to 18.6 was obtained using ≥2/5 tests as a cut-off point. Conclusion Visual assessment by physiotherapists of head-eye movement control tests is reliable. The test battery is able to discriminate between patients with chronic neck pain and healthy controls. There were no differences in performance between the sitting and standing positions. The test battery can therefore be reduced to five tests. Further research is needed to identify the test-retest stability and responsiveness.

Local dynamic stability as a responsive index for the evaluation of rehabilitation effect on fall risk in patients with multiple sclerosis: a longitudinal study. BMC Res Notes 2013; 6:260. [PMID: 23835061 PMCID: PMC3720262 DOI: 10.1186/1756-0500-6-260] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2012] [Accepted: 07/01/2013] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Gait and balance problems are common in patients with multiple sclerosis, leading to high risk for falls. Local Dynamic Stability (LDS), a non-linear gait stability index, has been advocated as an early indicator of risk for falls. With this longitudinal study over three weeks, we aimed to assess the responsiveness of Local Dynamic Stability to a rehabilitation program and to compare it to other measures. METHODS Eighteen patients (mean 54 years, median EDSS score: 5) participated. They were admitted to inpatient rehabilitation and received a three weeks individually tailored program. They performed a 3-minute walking test at the beginning and at the end of the stay, as well as pain, wellbeing, fatigue, and balance assessment. The Local Dynamic Stability was computed from the acceleration signals measured with a 3D-accelerometer. RESULTS At the end of the rehabilitation process, patients reported reduced pain (Effect Size: -0.7), fatigue (ES:-0.6), and increased wellbeing (ES: 1.1). A small positive effect on static balance was observed (ES: 0.3). LDS was improved (ES: 0.6), and the effect was higher than walking speed improvement (ES: 0.4). CONCLUSIONS The Local Dynamic Stability seemed responsive to assess rehabilitation effects in patients with multiple sclerosis. It could constitute a valuable gait quality index, which could evaluate potential effects of rehabilitation on fall risk. TRIAL REGISTRATION Current Controlled Trials ISRCTN69803702.

Robotic-assisted step training (lokomat) not superior to equal intensity of over-ground rehabilitation in patients with multiple sclerosis. Neurorehabil Neural Repair 2011; 26:212-21.

Abstract
BACKGROUND Robot-assisted gait training (RAGT) has been suggested as an intervention to improve walking capacity in patients with multiple sclerosis (MS). OBJECTIVE This study aimed to evaluate whether RAGT (Lokomat) is superior to over-ground walking training in terms of quality of life, activity level, and gait. METHODS A total of 67 patients with MS with the Expanded Disability Status Scale (EDSS) 3.0 to 6.5 were randomized to walking or RAGT, in addition to multimodal rehabilitation. Primary outcomes were walking speed, activity level (estimated metabolic equivalent, metabolic equivalents [METs], using an accelerometer), and quality of life (Well-Being Visual Analogue Scale (VAS) and EQ-5D European VAS. RESULTS In all, 49 patients finished the interventions. Mean age was 56 years (range 36-74 years), mean EDSS was 5.8 (3.0-6.5), and the preferred walking speed at baseline was 0.56 m/s (0.06-1.43 m/s). Before rehabilitation, participants spent on average 68 min/d at an MET ≥ 3. The walking group improved gait speed nonsignificantly more than the RAGT; the upper bound of the confidence interval (CI) did not exclude a clinically relevant benefit (defined as a difference of 0.05 m/s) in favor of the walking group; the lower bound of the CI did exclude a clinically important benefit in favor of the Lokomat. Quality of life improved in both groups, with a nonsignificant between-group difference in favor of the walking group. Both groups had reduced their activity by 8 weeks after the rehabilitation. CONCLUSION It is unlikely that RAGT is better than over-ground walking training in patients with an EDSS between 3.0 and 6.5.
