Descriptions of movement experiences in the Body Awareness Rating Scale - Movement Quality and Experience evaluation. A qualitative study of patients diagnosed with hip osteoarthritis.

Background: Patients' access to movement experiences is implemented in the evaluation tool Body Awareness Rating Scale - Movement Quality and Experience, with its two intertwined parts: 1) the physiotherapist's observations of movement quality; and 2) the patient's descriptions of immediate movement experiences.Objective: To study movement experiences and reflections described by patients diagnosed with hip osteoarthritis when guided to explore simple daily-life movements in this particular evaluation context.Design: An explorative qualitative study with open-ended questions following each of the 12 movements integrated into the evaluation.Methods: 35 participants diagnosed with hip osteoarthritis were included; 28 women and 7 men, aged 23-78 years. Their descriptions were audiotaped, transcribed verbatim and analyzed in accordance with qualitative content analysis.Results: The patients described experiences of a dynamic adaptation of movement strategies based on sensations from the moving body. Two interrelated categories of movement awareness were identified: 1) Experienced movement challenges, including three sub-categories; a) Lack of contact, b) Movement changed by symptoms, and c) Compensational movement habits, and 2) Movement components promoting well-being, including three sub-categories; a) Integrating balance, breathing and awareness into movement, b) Small, simple, soft and safe movements, and c) A taste of own movement resources for daily life.Conclusions: The Body Awareness Rating Scale - Movement Quality and Experience provides a platform for patients to become aware of and describe their movement habits and resources in own words, intertwined with the physiotherapist movement observations. Derived descriptions reflect a patient perspective to be implemented in therapy.

Discriminative Validity of the Pain Attitudes and Beliefs Scale for Physical Therapists.

BACKGROUND: The Pain Attitudes and Beliefs Scale (PABS) for Physical Therapists aims to measure clinicians' biomedical and biopsychosocial treatment orientations regarding nonspecific low back pain. OBJECTIVE: The objective of this study was to assess whether the PABS can differentiate between subgroups of physical therapists hypothesized to differ in treatment orientations. DESIGN: This study was a cross-sectional survey. METHODS: The PABS was completed by 662 Norwegian physical therapists with a diversity of professional backgrounds. Twenty-four a priori hypotheses on expected differences in PABS scores were formulated. Sufficient discriminative ability was defined as a minimum of 75% confirmed hypotheses. Hypotheses on differences in scores were tested for the biomedical and biopsychosocial subscales separately as well as for combinations of the 2 subscales, representing responders with high biomedical and low biopsychosocial PABS scores and vice versa. RESULTS: Of the 24 hypotheses, only 15 (62.5%) were confirmed. Between-group differences concerning the separate subscales were small, varying from -0.63 to 1.70 scale points, representing values up to 6.0% of the total subscale ranges. Between-group differences were larger when combined subscales were used, varying from 1.80 to 6.70 points, representing values up to 25.1% of the total subscale ranges. Despite little spread in scores, 24% of respondents demonstrated extreme attitudes. LIMITATIONS: The lack of convincing scientific evidence from previous research on differences in attitudes and beliefs between physical therapists was a limitation for the formulation of hypotheses. CONCLUSIONS: Discriminative validity of separate subscales of the PABS was not supported. Combining the 2 subscales into global treatment attitudes enabled better discrimination. Little spread in biomedical and biopsychosocial orientations explains why more than one-third of the hypotheses were not confirmed. Either Norwegian physical therapists are basically similar in their treatment orientation or the PABS is not able to detect any differences between them.

Peak oxygen uptake and breathing pattern in COPD patients--a four-year longitudinal study.

BACKGROUND: Activities of daily living in patients with chronic obstructive pulmonary disease (COPD) are limited by exertional dyspnea and reduced exercise capacity. The aims of the study were to examine longitudinal changes in peak oxygen uptake (V̇O2peak), peak minute ventilation (V̇Epeak) and breathing pattern over four years in a group of COPD patients, and to examine potential explanatory variables of change. METHODS: This longitudinal study included 63 COPD patients, aged 44-75 years, with a mean forced expiratory volume in one second (FEV1) at baseline of 51 % of predicted (SD = 14). The patients performed two cardiopulmonary exercise tests (CPETs) on treadmill 4.5 years apart. The relationship between changes in V̇O2peak and V̇Epeak and possible explanatory variables, including dynamic lung volumes and inspiratory capacity (IC), were analysed by multivariate linear regression analysis. The breathing pattern in terms of the relationship between minute ventilation (V̇E) and tidal volume (VT) was described by a quadratic equation, VT = a + b∙V̇E + c∙V̇E (2), for each test. The VTmax was calculated from the individual quadratic relationships, and was the point where the first derivative of the quadratic equation was zero. The mean changes in the curve parameters (CPET2 minus CPET1) and VTmax were analysed by bivariate and multivariate linear regression analyses with age, sex, height, changes in weight, lung function, IC and inspiratory reserve volume as possible explanatory variables. RESULTS: Significant reductions in V̇O2peak (p < 0.001) and V̇Epeak (p < 0.001) were related to a decrease in resting IC and in FEV1. Persistent smoking contributed to the reduction in V̇O2peak. The breathing pattern changed towards a lower VT at a given V̇E and was related to the reduction in FEV1. CONCLUSION: Increasing static hyperinflation and increasing airway obstruction were related to a reduction in exercise capacity. The breathing pattern changed towards more shallow breathing, and was related to increasing airway obstruction.

Virtual reality training for upper extremity in subacute stroke (VIRTUES): study protocol for a randomized controlled multicenter trial.

BACKGROUND: Novel virtual reality rehabilitation systems provide the potential to increase intensity and offer challenging and motivating tasks. The efficacy of virtual reality systems to improve arm motor function early after stroke has not been demonstrated yet in sufficiently powered studies. The objective of the study is to investigate whether VR training as an adjunct to conventional therapy is more effective in improving arm motor function in the subacute phase after stroke than dose-matched conventional training, to assess patient and therapist satisfaction when working with novel virtual reality training and to calculate cost-effectiveness in terms of resources required to regain some degree of dexterity. METHODS/DESIGN: Randomized controlled observer-blind trial. DISCUSSION: Virtual reality systems are promising tools for rehabilitation of arm motor function after stroke. Their introduction in combination with traditional physical and occupational therapy may enhance recovery after stroke, and at the same time demand little personnel resources to increase training intensity. The VIRTUES trial will provide further evidence of VR-based treatment strategies to clinicians, patients and health economists. TRIAL REGISTRATION: ClinicalTrials.gov NCT02079103.

Airway obstruction, dynamic hyperinflation, and breathing pattern during incremental exercise in COPD patients.

Ventilatory capacity is reduced in chronic obstructive pulmonary disease (COPD) patients. Tidal volume (V T) is lower and breathing frequency higher at a given ventilation (V E) compared to healthy subjects. We examined whether airflow limitation and dynamic hyperinflation in COPD patients were related to breathing pattern. An incremental treadmill exercise test was performed in 63 COPD patients (35 men), aged 65 years (48-79 years) with a mean forced expiratory volume in 1 sec (FEV1) of 48% of predicted (SD = 15%). Data were averaged over 20-sec intervals. The relationship between V E and V T was described by the quadratic equation V T = a + bV E + cV E (2) for each subject. The relationships between the curve parameters b and c, and spirometric variables and dynamic hyperinflation measured as the difference in inspiratory capacity from start to end of exercise, were analyzed by multivariate linear regression. The relationship between V E and V T could be described by a quadratic model in 59 patients with median R (2) of 0.90 (0.40-0.98). The linear coefficient (b) was negatively (P = 0.001) and the quadratic coefficient (c) positively (P < 0.001) related to FEV1. Forced vital capacity, gender, height, weight, age, inspiratory reserve volume, and dynamic hyperinflation were not associated with the curve parameters after adjusting for FEV1. We concluded that a quadratic model could satisfactorily describe the relationship between V E and V T in most COPD patients. The curve parameters were related to FEV1. With a lower FEV1, maximal V T was lower and achieved at a lower V E. Dynamic hyperinflation was not related to breathing pattern when adjusting for FEV1.

Physical activity and longitudinal change in 6-min walk distance in COPD patients.

BACKGROUND: The 6-min walk distance (6MWD) is widely used to evaluate functional capacity in patients with chronic obstructive pulmonary disease (COPD). AIM: To examine predictors for longitudinal change in 6MWD including self-reported physical activity, smoking habits, body composition, exacerbations, comorbidity and lung function. METHODS: The cohort included 389 patients aged 44-75 years, with clinically stable COPD in GOLD stages II-IV. The follow-up time was 3 years. Measurements included 6MWD, spirometry, fat and fat free mass index (FMI and FFMI), and assessment of physical activity, smoking habits, comorbidities and exacerbations by questionnaires. Generalized estimating equations (GEE) regression analyses were used to analyze predictors for the change in 6MWD. RESULTS: There was a reduction in 6MWD from baseline to 3 years for patients in GOLD stages III and IV (B = -36 m, 95% CI = -51 to -7, p = 0.009 and B = -79 m, CI = -125 to -20, p = 0.007). The unadjusted GEE analysis demonstrated that baseline self-reported physical activity level, forced expiratory volume in one second (FEV1), forced vital capacity, FFMI, GOLD stages and age predicted change in 6MWD, but in the adjusted GEE analysis only self-reported physical activity level (p = 0.001) and FEV1 (p = 0.019) predicted change over time. CONCLUSION: Patients in GOLD stage II maintained their functional capacity assessed by 6MWD over 3 years, while it was significantly reduced for patients in GOLD stages III and IV. Level of physical activity and FEV1 were predictors for longitudinal change in functional capacity.

Pain in older persons with severe dementia. Psychometric properties of the Mobilization-Observation-Behaviour-Intensity-Dementia (MOBID-2) Pain Scale in a clinical setting.

BACKGROUND: To assess pain in older persons with severe dementia is a challenge due to reduced self-report capacity. Recently, the development and psychometric property testing of the Mobilization-Observation-Behaviour-Intensity-Dementia (MOBID) Pain Scale was described using video-recording. The purpose of this article was to present the further development of this instrument. In MOBID-2 Pain Scale, the assessment of inferred pain intensity is based on patient's pain behaviours in connection with standardized, guided movements of different body parts (Part 1). In addition, MOBID-2 includes the observation of pain behaviours related to internal organs, head and skin registered on pain drawings and monitored over time (Part 2). OBJECTIVE: The aim of this study was to examine psychometric properties of the MOBID-2 Pain Scale, like inter-rater and test-retest reliability, internal consistency, as well as face-, construct- and concurrent validity. SUBJECTS AND SETTING: Patients with severe dementia (n = 77) were examined by 28 primary caregivers in clinical practice, who concurrently and independently completed the MOBID-2 Pain Scale. Characteristics of the patients' pain were also investigated by their physicians (n = 4). RESULTS: Prevalence of any pain was 81%, with predominance to the musculoskeletal system, highly associated with the MOBID-2 overall pain score (rho = 0.82). Most frequent and painful were mobilizing legs. Pain in pelvis and/or genital organs was frequently observed. Moderate to excellent agreement was demonstrated for behaviours and pain drawings (kappa = 0.41-0.90 and kappa = 0.46-0.93). Inter-rater and test-retest reliability for pain intensity was very good, ICC (1, 1) ranging 0.80-0.94 and 0.60-0.94. Internal consistency was highly satisfactory; Cronbach's alpha ranging 0.82-0.84. Face-, construct- and concurrent validity was good. Overall pain intensity by MOBID-2 was well correlated with physicians' clinical examination and defined pain variables (rho = 0.41-0.64). CONCLUSION: On the basis of pain behaviours, standardized movements and pain drawings, MOBID-2 Pain Scale was shown to be sufficiently reliable, valid and time-effective for nurses to assess pain in patients with severe dementia.

Long-term follow-up of disability pensioners having musculoskeletal disorders.

BACKGROUND: Previously we have conducted a randomised controlled trial (RCT) to evaluate the effect of a brief cognitive behavioural program with a vocational approach aiming to return disability pensioners with back pain to work, as compared to no intervention. One year after the intervention, 10 participants (22%) who received the program and 5 (11%) in the control group reported to have entered a return to work process. The aims of this study were to evaluate long-term effects of the intervention, and compare this effect to 2 reference populations not participating in the original trial. METHODS: Three groups of disability pensioners were investigated: 1) Disability pensioners having back pain (n = 89) previously participating in the RCT (randomized to either a brief cognitive behavioural intervention or to a control group), 2) 342 disability pensioners having back pain, but refusing to participate in the study and 3) 449 disability pensioners having other musculoskeletal disorders than back pain. Primary outcome was return to work, defined as a reduction in payment of disability pension. RESULTS: Only 2 of 89 (2.3%) participants from the RCT had reduced disability pension at 3-years follow-up, both from the control group. None of the participants that had been in a process of returning to work after 1 year had actually gained employment at 3-years follow-up. In the 2 groups not participating in the previous RCT, only 4 (1.2%) and 8 (1.6%) had returned to work after 3 years respectively. CONCLUSION: The number of pensioners who returned to work was negligible in all groups regardless of having participated in a cognitive behavioural intervention or not.

The effect of two exercise regimes; motor control versus endurance/strength training for patients with whiplash-associated disorders: a randomized controlled pilot study.

OBJECTIVE: To compare the effect of exercise regimes with focus on either motor control training or endurance/strength training for patients with whiplash-associated disorders in subacute phase. DESIGN: Randomized controlled trial. SETTING: An outpatient spine clinic in Norway. PARTICIPANTS: Twenty-five subjects with a whiplash-associated disorder still having symptoms or disability six weeks after injury. INTERVENTIONS: The participants received 6-10 sessions of physiotherapy for six weeks with focus on either motor control or endurance and strength of neck muscles. MEASUREMENTS: The primary outcome measure was the Neck Disability Index. Secondary outcome measures were pain intensity, neck functioning and sick leave. RESULTS: No statistical significant differences concerning primary and secondary outcome measures were demonstrated between the groups. Approximately half of the participants in both groups obtained a clinically important change (improvement) on perceived disability assessed by Neck Disability Index at six weeks and one-year follow-up. The changes within both groups were statistically significant at six weeks, but not at one-year follow-up. For most pain-related variables clinical significant improvement was demonstrated in both groups at six weeks, but for fewer participants at one year. There was also statistical significant improvement within groups in some of the physical performance tests at one-year follow-up. CONCLUSION: The changes associated with motor control training and endurance/ strength training of neck muscles were similar for reduced disability, pain and for improving physical performance. With a low number of participants and no control group, however, we cannot be sure whether the improvements are due to interventions or other reasons.

Pain behaviour and pain intensity in older persons with severe dementia: reliability of the MOBID Pain Scale by video uptake.

Advancing age is associated with high prevalence of dementia, often combined with under-diagnosed and under-treated pain. A nurse-administered assessment tool has been developed to unmask pain during standardised, guided movements, called Mobilisation-Observation-Behaviour-Intensity-Dementia (MOBID) Pain Scale. The aim was to examine intra- and inter-rater reliability of pain behaviour indicators, inferred pain intensity, and the overall MOBID Pain Score. Twenty-six nursing home patients with severe dementia and chronic pain, 11 primary caregivers and three external raters at the Red Cross Nursing Home, Bergen were included. During video uptake the patients were guided by their primary caregivers to standardised movements of different body parts. Pain behaviour indicators (pain noises, facial expression and defence) were registered for each movement with subsequent rating of pain intensity by external raters, who assessed and scored the videos concurrently and independently at day 1, 4 and 8. Facial expression was most commonly observed, followed by pain noises and defence. Repeated assessments increased the number of observed pain behaviours, but did not improve reliability. Inter-rater reliability was highest for noises, followed by defence and facial expression (kappa = 0.44-0.92, kappa = 0.10-0.76 and kappa = 0.05-0.76 respectively, at day 8). Mobilisation of arms and legs were rated most painful. Intra- and inter-rater reliability of overall pain were very good [intraclass correlation coefficient (1,1) ranging 0.92-0.97 and 0.94-0.96 respectively, at day 8]. Reliability of pain intensity scores tended to increase by repeated assessment. Using video uptake, MOBID Pain Scale was shown to be sufficiently reliable to assess pain in older persons with severe dementia.

A modified version of the non-communicating children pain checklist-revised, adapted to adults with intellectual and developmental disabilities: sensitivity to pain and internal consistency.

UNLABELLED: Despite enhanced interest in manifestations of pain in adults with intellectual and developmental disabilities (IDD), the characteristics of pain behavior in this group have seldom been examined. The aim of the present study was to provide a sensitive pain behavior scale for adults with IDD. The participants, 228 adults (mean age, 38.7 years) with different levels of IDD, were videotaped before and during an influenza vaccination and scored using the Non-Communicating Children's Pain Checklist-Revised (NCCPC-R). Observed pain behaviors not captured by the NCCPC-R, was also registered. Sensitivity to pain of all 27 items was examined by Signed Rank test, internal consistency by Cronbach's alpha, and sensitivity to change of the total scale by Standardized Response Mean (SRM). Thirteen items were excluded from the original NCCPC-R scale; 4 new items were added, making a modified scale of 18 items. This scale, named the Non-Communicating Adults Pain Checklist-Revised (NCAPC), was rescored and examined for psychometric properties in a random sample (N = 89). Sensitivity to pain of all items (P < .05) and high internal consistency (alpha = 0.773) were demonstrated. Large sensitivity to pain at all levels of IDD was shown (SRM, 1.20 to 2.07). Better psychometric properties were demonstrated for NCAPC than NCCPC-R in the target population. PERSPECTIVE: This article presents initial psychometric properties of a new measure, the NCAPC, evaluating pain behavior in adults with IDD. This measure could help clinicians to better capture pain expressions in this population and contribute to better pain management for this group of patients.

Reliability and validity of the back performance scale: observing activity limitation in patients with back pain.

STUDY DESIGN: A single group design to examine reliability and validity of the Back Performance Scale. OBJECTIVES: To examine intertester reliability, test-retest reliability, and concurrent validity of the Back Performance Scale. SUMMARY OF BACKGROUND DATA: The Back Performance Scale is a condition-specific performance measure of activity limitation in patients with back pain. It includes five tests of daily activities requiring mobility of the trunk: sock test, pick-up test, roll-up test, fingertip-to-floor test, and lift test. Discriminative ability and responsiveness to important change have previously been demonstrated. METHODS: A total of 41 patients with back pain participated in the study. Two physiotherapists examined test performances concurrently, but independently. The patients filled in three questionnaires, two reflecting perceived disability (Der Funktionsfragenbogen Hannover, Roland-Morris Disability Questionnaire) as well as one for fear avoidance of daily activities and work (Fear Avoidance Belief Questionnaire). One physiotherapist retested the patients after 2 to 3 days. RESULTS: Intertester agreement of the Back Performance Scale sum score was very high (intraclass correlation coefficient 2.1): 0.996. Within-patient standard deviation (sw) on the 16-point Back Performance Scale was very low: 0.25. Test-retest reliability was high (intraclass correlation coefficient = 0.91, sw = 1.3). Intertester agreement of the separate tests was also very high, ranging from kappa= 0.90-1.00. Test-retest reliability was moderate to high (kappa= 0.55-0.83). A high correlation was demonstrated between the Back Performance Scale and the Der Funktionsfragenbogen Hannover: Spearman rho (rho) = 0.825, P < 0.01. Correlation between the Back Performance Scale and Roland-Morris Disability Questionnaire was moderate: rho = 0.454, P < 0.01. No correlation was demonstrated between the Back Performance Scale and the Fear Avoidance Belief Questionnaire. CONCLUSION: The Back Performance Scale appears to be a reliable and valid outcome measure of activity limitation.
