- Study design: Inter-rater reliability study. Background: Physiotherapists (PTs) use clinical tests including movement tests to identify faulty movement patterns. Aims: To investigate the inter-rater-reliability of active movement tests in the cervical spine, shoulder joint and scapulo-thoracic joint, and to describe the reasons for judgment of a positive test. Methodology: Four PTs, two experienced and two recently educated (novice), rated performance of five movement tests for 36 participants. Twenty-one of the participants were patients under treatment because of neck and/or shoulder problems, while 15 participants declared no problem from this region of the body. All tests were video recorded and the ratings were done by observing the video recordings. First, the PTs judged the tests as negative (the movement being ideally performed) or positive (the movement not being ideally performed). Then, the PTs described why the movements that they judged positive were not being ideally performed, using a predefined protocol, which represented different movement quality aspects. The inter-rater reliability was calculated for each test using Kappa statistics between the two experienced and the two novice PTs, respectively, and between each of the experienced and each of the novice PTs. Major findings: The experienced PTs had a higher inter-rater reliability than the novice PTs. The reasons for considering a movement test being positive differed highly between the (novice) PTs. Principal conclusion: This study supports previous studies concluding that the observation of active movement tests is reliable when assessed by experienced PTs. Novice PTs might benefit from further supervision.

- Study Design Randomized controlled trial. Background Low back pain is a common disorder. Patients with low back pain frequently have aberrant and pain-provocative movement patterns that often are addressed with motor control exercises. Objective To compare the effects of low-load motor control (LMC) exercise and those of a high-load lifting (HLL) exercise. Methods Seventy participants with recurrent low back pain, who were diagnosed with nociceptive mechanical pain as their dominating pain pattern, were randomized to either LMC or HLL exercise treatments. Participants were offered 12 treatment sessions over an 8-week period. All participants were also provided with education regarding pain mechanisms. Methods Participants were assessed prior to and following treatment. The primary outcome measures were activity (the Patient-Specific Functional Scale) and average pain intensity over the last 7 days (visual analog scale). The secondary outcome measure was a physical performance test battery that included 1 strength, 3 endurance, and 7 movement control tests for the lumbopelvic region. Results Both interventions resulted in significant within-group improvements in pain intensity, strength, and endurance. The LMC group showed significantly greater improvement on the Patient-Specific Functional Scale (4.2 points) compared with the HLL group (2.5 points) (P<.001). There were no significant between-group differences in pain intensity (P = .505), strength, and 1 of the 3 endurance tests. However, the LMC group showed an increase (from 2.9 to 5.9) on the movement control test subscale, whereas the HLL group showed no change (from 3.9 to 3.1) (P<.001). Conclusion An LMC intervention may result in superior outcomes in activity, movement control, and muscle endurance compared to an HLL intervention, but not in pain intensity, strength, or endurance.

- BACKGROUND: Low back pain (LBP) is a common pain problem in powerlifters. There is a lack of evidence to guide powerlifters and health-care professionals in understanding the role of powerlifting in the development of LBP and treatment of injuries in powerlifters. This study aimed to describe functional impairments and patho-anatomical findings in eight powerlifters with and without LBP. METHODS: First, four powerlifters with LBP were recruited. Each powerlifter was then matched with a pain-free lifter (Control) by age, Body Mass Index and competition weight class. They all performed physical performance tests and were examined with magnetic resonance imaging. Four weeks prior to the examination the powerlifters also recorded training load. Powerlifters with LBP were also examined by a physiotherapist in order to define their pain and impairments. RESULTS: The four male powerlifters with LBP had a nociceptive pain associated with non-ideal squatting technique, higher flexibility in their lumbar spine than in their hips and patho-anatomical findings such as degenerated discs (four), spondylolysis (one) and spinal stenosis (one). However, the controls also showed similar functional impairments and patho-anatomical findings. CONCLUSIONS: Powerlifters with and without LBP show similar functional impairments and patho-anatomical findings. However, powerlifters' LBP seems associated with pain during movement and loading of the lumbar spine. The association and causation between specific functional impairments, patho-anatomical findings and LBP in powerlifters has to be further investigated in studies including more participants.

Ambulance Work : Relationships between occupational demands, individual characteristics and health-related outcomes

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Although musculoskeletal disorders (MSDs) and other health complaints are an occupational problem for ambulance personnel, there is a lack of knowledge regarding work-related factors associated with MSDs and other health complaints. The overall aim of this thesis was to investigate the relationships between occupational demands, individual characteristics and health-related outcomes among ambulance personnel. A random sample of 234 female and 953 male ambulance personnel participated in a national questionnaire survey on work-related factors, and musculoskeletal and other health complaints. Physical demands was associated with activity limitation due to neck-shoulder and low-back complaints among the female personnel. Among the male personnel, physical demands was associated with low-back complaints and activity limitation due to low-back complaints. Psychological demands was significantly associated with neck-shoulder complaints, sleeping problems, headache and stomach symptoms among both female and male ambulance personnel. Worry about work conditions was associated with musculoskeletal disorders and sleeping problems, headache and stomach symptoms. A local sample of 26 ambulance personnel was followed during a 24-hour work shift and for the next two work-free days. Subjective stress- and energy levels, and cortisol levels were measured at regular intervals, and heart rate was registered continuously by electrocardiogram (ECG). Autonomic reactivity to standardized tests before (pre-work) and at the end of the work shift (post-work) was also investigated. For the whole group, baseline values of heart rate were higher pre-work than post-work, but autonomic reactivity did not differ. Increased reactivity to the mental test, modest deviation in heart rate variability (HRV) pattern during the late night hours at work and higher morning cortisol values during work than during leisure time were observed in personnel with many health complaints, but not among their co-workers without or with few complaints. Ambulance personnel with many health complaints also reported higher psychological demands and tended to be more worried about work conditions. Heart rate (HR), lactate level (LL) and perceived exertion (RPE) were investigated in 17 female and 48 male ambulance personnel during a simulated standardized work task “carry a loaded stretcher”. The ambulance personnel had to carry the loaded stretcher (920 N) up and down three flights of stairs twice. The high physiological strain (HR, LL, RPE) for the male, and near or at maximal strain for the female ambulance personnel, implied the importance to identify what kind of physical capacity is most important for ambulance personnel. Therefore, the explained variance of developed fatigue by tests of cardiorespiratory capacity, muscular strength and endurance, and coordination was investigated. The results showed that VO2max and isometric back endurance were important predictors for development of fatigue when carrying a loaded stretcher. The influence of body size on the relationships between maximal strength and functional performance was investigated in a methodological study. The results confirm that the assessment of physical performance could be confounded by the body weight. Therefore, the models for explaining development of fatigue when carrying the loaded stretcher were adjusted for height and weight. Including height in the models significantly increased the explained variance of accumulated lactate among female, but not among male personnel. Lactate levels were higher among short compared to tall female personnel. Weight had no effect on any of the models. In conclusion, the national survey showed that self-reported physical demands was a risk factor of having MSDs, and that self-reported psychological demands and worry about work were important risk factors of having MSDs and other health complaints. Stress monitoring of ambulance personnel during work and leisure time showed that physiological and subjective stress markers did not show any differences between the 24-hour ambulance work shift and leisure time afterwards. However, ambulance personnel with many health complaints had certain physiological changes during the work shift in comparison with the next two work-free days. The physiological and subjective responses during carrying a loaded stretcher, especially among the female ambulance personnel, showed that female and male ambulance personnel could be exposed to internal exposures at different levels when performing the same work task. A better understanding of the relationships between occupational demands and health-related outcomes require further studies on age- and gender matched groups in long-term perspective studies.

- The aims of the study were (1) to investigate the effects of participation in low impact body conditioning classes on physical fitness in sedentary women at different ages and (2) to examine the correspondence between physical self-concept and participation in, and fitness change after, the participation. Ninety-two sedentary women (mean age 44.2 years) participated in 11-weeks of bi-weekly classes that included cardiovascular, strength, core, endurance and mobility exercises, all performed in synchrony with music. Cardiorespiratory fitness, maximal lifting strength, mobility and balance tests were performed pre- and post the exercise period and the short-form Physical Self-Description Questionnaire (PSDQ-S) was completed. Zero-order Spearman correlation analyses showed that women who rated the PSDQ-S dimension Sport competence higher participated in a larger number of sessions (rs=0.24, p=0.040). At post-tests, all participants had increased their balance, the participants aged 20-34 years had increased their lifting strength, and the participants aged 35-65 years had increased their cardiorespiratory fitness and mobility. Most PSDQ-S dimensions did not affect performance change, but the perception of being physically active was related to increased cardiovascular fitness. We conclude that women with a sedentary lifestyle who wish to increase their physical capacity benefit from music exercise and that inquiries about perceived sport competence and physical activity can improve recommendations made by strength and conditioning professionals.

- Background Olympic weightlifting and powerlifting are two sports that expose the body to great forces. Injury characteristics have not been systematically reviewed for these two growing sports.Objective The purpose of this study was to systematically review the literature regarding various definitions of injuries used, injury localisation, the prevalence and incidence of injuries and the associated risk factors for injuries in weightlifting and powerlifting.Design Systematic review.Data sources Five databases, PubMed, MEDLINE, SPORTDiscus, Scopus and Web of Science, were searched between 9 March and 6 April 2015.Eligibility criteria for selecting studies Studies assessing injury incidence and prevalence in Olympic weightlifting and powerlifting were included. The Quality assessment tool for observational cohort and cross-sectional studies was used to assess methodological quality.Results 9 studies were included in the review. Injury was defined fairly consistently across studies. Most studies were of low methodological quality. The spine, shoulder and the knee were the most common injury localisations in both sports. The injury incidence in weightlifting was 2.4–3.3 injuries/1000 hours of training and 1.0–4.4 injuries/1000 hours of training in powerlifting. Only one retrospective study had analysed possible risk factors.Summary/conclusions The risk of injury in both sports were similar to other non-contact sports also requiring strength/power, but low compared to contact sports. The severity of injuries differed in the included studies. Since little has been studied regarding possible risk factors to injuries, further research is therefore warranted to explain why athletes get injured and how to prevent injuries.Trial registration number PROSPERO CRD42015014805.

Muscle strength assessment from functional performance tests : role of body size
- 2003

- The aim of the study was to test the hypothesis that the body size plays an important role in assessment of muscle ability to exert force by standard functional performance tests. Twenty-one male students were tested on maximal isometric lift, one leg rising, vertical jump, and box lift tests, and the maximal isokinetic strength of hip and knee extensors was also recorded. When indices of the 4 functional performance tests were related to the strength of each of the 2 leg extensor muscle groups, only maximal isometric lift demonstrated positive correlation with knee extensors strength. When muscle strength was corrected for body mass, however, the aforementioned relationship became insignificant, but the 1 leg rising performance demonstrated a positive relationship with knee extensor strength. In addition, maximal isometric lift and 1 leg rising test performance provided positive and negative correlation, respectively, with body mass. The obtained findings were in line with the effects of scale applied on the tested performance. We generally conclude that the assessment of muscle capability to exert force based on some standard functional performance tests could be confounded by the body size effect.
