This review article discusses the aspects of sports medicine where musculoskeletal Doppler ultrasound has valuable contribution in diagnosis and/or treatment of some of the typical musculoskeletal sports injuries. Also, conditions where the Doppler ultrasound has no value are discussed. Some guidelines and recommendations are based on personal experience since no evidence in literature exists. The basic technical background of Doppler ultrasound and typical artefacts will be discussed, in order to understand and interpret the Doppler result. Recommendations for the Doppler settings are given in relevant sections. Ultrasound guided treatments where the Doppler result is used as a guide are mentioned and discussed.

Functional ability, including the ability to perform activities of daily living (ADL), is considered a core outcome domain in chronic pain clinical trials and is usually assessed through generic or disease-specific self-report questionnaires. Research, however, indicates that self-report and performance-based assessment of ADL offer distinct but complementary information about ability. The present study, therefore, investigated the applicability of a performance-based measure of ADL ability, the Assessment of Motor and Process Skills (AMPS), among 50 women with chronic widespread pain. The investigated psychometric properties of the AMPS included discrimination between a sample of healthy women and those with chronic widespread pain, as well as stability when no intervention was provided and sensitivity to change following intervention. Data were obtained based on a repeated measures design performing AMPS evaluations twice pre- and twice post-rehabilitation. Results indicated that the ADL motor ability measures of the participants were significantly lower than those of healthy women of same age, the ADL motor and ADL process ability measures remained stable when no intervention was provided and the ADL motor ability measures were sensitive to change following a 2-week interdisciplinary rehabilitation program. A weak correlation (r(s)=-0.35) was found between self-reported ADL ability as measured by the physical function subscale of the Functional Impact Questionnaire (FIQ) and performance-based ADL motor measures, and no correlation (r(s)=-0.02) was found between FIQ ADL measures and ADL process ability, supporting the need for both performance-based and self-reported assessment of ADL.

QT interval prolongation during spontaneous episodes of hypoglycaemia in type 1 diabetes: the impact of heart rate correction

Christensen, T. F., Tarnow, L., Randløv, J., Kristensen, L. E., Struijk, J. J., Eldrup, E. & Hejlesen, O. K., sep. 2010, I : Diabetologia. 53, 9, s. 2036-41 6 s.

AIMS/HYPOTHESIS: Prolongation of the heart rate corrected QT interval (QTc) is seen during episodes of hypoglycaemia in type 1 diabetes. We studied the relationship between spontaneous hypoglycaemia and the QT interval and hypothesised that the choice of heart rate correction affects the observed change in QTc.

METHODS: Twenty-one participants with type 1 diabetes (aged 58 +/- 10 years with duration of diabetes 34 +/- 12 years) had continuous glucose and ECG monitoring for 72 h. QT and RR intervals were measured during hypoglycaemia (blood glucose or continuous glucose measurements <or=3.5 mmol/l) and compared with euglycaemia (5-12 mmol/l). QT intervals were measured using the semi-automated tangent method from signal-averaged ECG and corrected using Bazett's formula, Fridericia's formula, the nomogram method and a linear subject-specific method.

RESULTS: Hypoglycaemia was present in 14 participants. With Bazett's formula, QTc changed significantly from euglycaemia to hypoglycaemia (422 +/- 30 vs 432 +/- 33 ms; p = 0.02). Heart rate, QT intervals and QTc corrected with formulas other than Bazett's were not associated with a significant change (p = 0.07-0.29). During hypoglycaemia, significantly lower values of QTc compared with the subject-specific method were seen for Fridericia's formula (p = 0.02) and the nomogram method (p = 0.04).

CONCLUSIONS/INTERPRETATION: Spontaneous hypoglycaemia was associated with a modest increase in QTc. Bazett's formula resulted in overcorrection of QTc while both Fridericia's formula and the nomogram method undercorrected the QTc compared with the subject-specific method during hypoglycaemia. The results may indicate that the use of a fixed heart rate correction formula can lead to misleading results in investigations of spontaneous hypoglycaemia.

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Function Index (BASFI) and the Bath Ankylosing Spondylitis Global Score (BAS-G) (ranges 0-10) have gained widespread in use as self-reported measures of disease activity, functional impairment and overall well-being in patients with ankylosing spondylitis and other spondyloarthropathies (SpA). In Denmark, BASDAI, BASFI and BAS-G are systematically used to monitor treatment response in patients treated with tumour necrosis factor (TNF) inhibitors. The purpose of the present study was to examine the reproducibility of the indices in anti-TNF-treated SpA patients already familiar with the use of the indices. Testing was performed twice on two different days (median interval 7 days, range 4-10 days) under standardised conditions in 26 out-clinic patients (median age 39 years, range 22-56 years). Limits of agreement were calculated as the 95% likely range for the difference between paired scores. Test-retest results were significantly intercorrelated with r (s) = 0.90 for BASDAI, 0.92 for BASFI and 0.74 for BAS-G. Limits of agreement for BASDAI, BASFI and BAS-G were +/-1.8, +/-1.4 and +/-3.2, respectively. Reproducibility as expressed as the mean of individual standard deviations was significantly poorer for BAS-G than for BASDAI and BASFI (p <0.01). Internal consistency reliability and construct validity of BASDAI and BASFI were acceptable. In conclusion, in a sample of anti-TNF-treated patients experienced with the use of BASDAI, BASFI and BAS-G, random measurement errors of the scores were not negligible. The finding should be considered when monitoring anti-TNF treatment in daily clinical practice.

Widespread pain and pain hypersensitivity are the hallmark of fibromyalgia, a complex pain condition linked to central sensitization. In this study the painDETECT questionnaire (PDQ), validated to identify neuropathic pain and based on pain quality items, was applied in a cross-sectional sample of patients with chronic widespread pain (CWP). The aims of the study were to assess the patient-reported sensory neuropathic symptoms by PDQ and to correlate these with tender point (TP) count and pressure-pain thresholds. Eighty-one patients (75 F, 6 M) with CWP (ACR-criteria) filled in the PDQ. Manual TP examination was conducted according to ACR guidelines. Computerized cuff pressure algometry was used for the assessment of pressure-pain detection thresholds (PDT, unit: kPa) and pressure-pain tolerance thresholds (PTT, unit: kPa). Mean TP count was 14.32 (range: 2-18), mean PDQ score 22.75 (range: 5-37). Mean PDT was 8.8 kPa (range: 2-36) and mean PTT 30.9 kPa (range: 4-85). Deep-tissue hyperalgesia was the predominant somatosensory symptom reported in 83%, but other neuropathic symptoms were also frequent, e.g. burning 51% and prickling 47%. Statistically significant correlations were found between PDQ score and TP count: r=0.35 (p

The predetermined sites of examination for tender points in fibromyalgia syndrome are frequently associated with myofascial trigger points

Ge, H., Wang, Y., Danneskiold-Samsøe, B., Nielsen, T. G. & Arendt-Nielsen, L., 1 jul. 2010, I : Journal of Pain. 11, 7, s. 644-51 8 s.

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

The aim of this present study is to test the hypotheses that the 18 predetermined sites of examination for tender points (TP sites) in fibromyalgia syndrome (FMS) are myofascial trigger points (MTrPs), and that the induced pain from active MTrPs at TP sites may mimic fibromyalgia pain. Each TP site was evaluated with manual palpation followed by intramuscular electromyographic (EMG) registration of spontaneous electrical activity to confirm or refute the existence of an MTrP in 30 FMS patients. Overall spontaneous pain intensity and pain pattern were recorded before manual identification of MTrPs. Local and referred pain pattern from active MTrPs were drawn following manual palpation at TP sites. RESULTS: Showed that most of the TP sites are MTrPs. Local and referred pain from active MTrPs reproduced partly the overall spontaneous pain pattern. The total number of active MTrPs (r = .78, P <.0001), but not latent MTrPs (r = -.001, P = .99), was positively correlated with spontaneous pain intensity in FMS. The current study provides first evidence that pain from active MTrPs at TP sites mimics fibromyalgia pain. MTrPs may relate to generalized increased sensitivity in FMS due to central sensitization. PERSPECTIVE: This article underlies the importance of active MTrPs in FMS patients. Most of the TP sites in FMS are MTrPs. Active MTrPs may serve as a peripheral generator of fibromyalgia pain and inactivation of active MTrPs may thus be an alternative for the treatment of FMS.

RATIONAL AND OBJECTIVE: Disease assessment and follow-up of rheumatoid arthritis (RA) patients require objective evaluation and quantification. Magnetic resonance imaging (MRI) has a large potential to supplement such information for the clinician, however, time spent on data reading and interpretation slow down development in this area. Existing scoring systems of especially synovitis are too rigid and insensitive to measure early treatment response and quantify inflammation. This study tested a novel automated, computer system for analysis of dynamic MRI data acquired from patients with RA, Dynamika-RA, which incorporates efficient data processing and analysis techniques.

Absolute treatment efficacy (via number needed to treat) of rheumatoid arthritis for each of the three available anti tumour necrosis factor alpha inhibiting therapies. Our aim was to indirectly compare the long-term efficacy of the available anti-tumour necrosis factor (TNF) therapies in patients with established rheumatoid arthritis. The results indicate that the absolute efficacy associated with use of these anti-TNF therapies is equivalent if applied in equivalent dosages. In standard dosages, infliximab (3 mg/kg/eight weeks) is only half as effective as adalimumab (40 mg/two weeks) and etanercept (25 mg twice weekly).

Biomechanical characteristics of the eccentric Achilles tendon exercise

Henriksen, M., Aaboe, J., Bliddal, H. & Langberg, H., 11 dec. 2009, I : Journal of Biomechanics. 42, 16, s. 2702-7 6 s.

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

BACKGROUND: Eccentric exercise has been shown to provide good short-term clinical results in the treatment of painful mid-portion chronic Achilles tendinopathies. However, the mechanisms behind the positive effects of eccentric rehabilitation regimes are not known, and research into the biomechanics of the exercise may improve our understanding.

METHODS: Sixteen healthy subjects performed one-legged full weight bearing ankle plantar and dorsiflexion exercises during which three-dimensional ground reaction forces (GRF), ankle joint kinematics and surface electromyography (EMG) of the lower leg muscles were recorded. Joint kinematics, GRF frequency contents, average EMG amplitudes, and Achilles tendon loads were calculated.

FINDINGS: The eccentric movement phase was characterized by a higher GRF frequency content in the 8-12 Hz range, and reduced EMG activity in the lower leg muscles. No differences in Achilles tendon loads were found.

INTERPRETATION: This descriptive study demonstrates differences in the movement biomechanics between the eccentric and concentric phases of one-legged full weight bearing ankle dorsal and plantar flexion exercises. In particular, the findings imply that although the tendon loads are similar, the tendon is vibrated at higher frequencies during the eccentric phase than during the concentric phases. This study provides data that may explain the mechanisms behind the effectiveness of eccentric exercises used in the treatment of Achilles tendinopathies.

Can stimulating massage improve joint repositioning error in patients with knee osteoarthritis?

Lund, H., Henriksen, M., Bartels, E. M., Danneskiold-Samsøe, B. & Bliddal, H., 2009, I : Journal of Geriatric Physical Therapy. 32, 3, s. 111-6 6 s.

PURPOSE: The purpose of this study was to investigate the effect of massage applied to the thigh muscles on joint repositioning error (JRE) in patients suffering from osteoarthritis (OA).We hypothesized that stimulating massage of the muscles around an osteoarthritic knee joint, could improve the neuromuscular function and thereby optimize the positive and minimize the negative performance factors in relation to an exercise program.

METHODS: In a cross-over design, 19 patients with knee osteoarthritis, mean age of 73.1 years (SD: 9.4; range 56 to 88 years), recruited from the local department of rheumatology, were randomly allocated to either receive massage and a week later, act as controls or vice versa. The applied massage consisted of stimulating massage of the quadriceps femoris, sartorious, gracilus, and hamstrings muscles for 10 min on the affected leg. Participants had their JRE measured before and immediately after the 10 min massage and control sessions. Data were analyzed by using paired t-test.

RESULTS: No significant change in JRE was observed (95% CI: -0.62 degrees to 0.85 degrees, p = 0.738).

CONCLUSION: Massage has no effect on the immediate joint repositioning error in patients with knee osteoarthritis, ie, if an improved JRE is important for improving the performance factors when exercising, stimulating massage may not be recommendable to use.

Disease-modifying anti-rheumatic drugs til behandling af ankyloserende spondylitis

Madsen, O. R. & Egsmose, C., 2009, I : Ugeskrift for Laeger. 171, 33, s. 2268-72 5 s.

Ankylosing spondylitis (AS) is an inflammatory disorder affecting the axial skeleton, peripheral joints, entheses and extra-articular sites. Patients with early disease, a higher level of erythrocyte sedimentation rate and/or peripheral arthritis might benefit from sulfasalazine. Otherwise, there is no evidence that disease-modifying anti-rheumatic (DMARDs) have a therapeutic effect in AS. Clinical evidence that greater TNF-inhibitor effectiveness can be achieved by combining with a DMARD is lacking, but further studies should be performed. More research is needed to clarify the role of DMARDs in the treatment of AS.
