Ultrasound Doppler Flow in Patients With Chronic Midportion Achilles Tendinopathy

OBJECTIVES: Ultrasound assessments of patients with chronic midportion Achilles tendinopathy include determining the degree of neovascularization using Doppler flow. A frequently used measure to quantify neovascularization is the modified Öhberg score. It is unknown whether the semiquantitative modified Öhberg score (0-4+) has higher reliability than a quantified measure of Doppler flow (0-100%). The purpose of this cross-sectional study was to evaluate the interobserver reliability of the modified Öhberg score and a surface area quantification (SAQ) method for Doppler flow in patients with chronic midportion Achilles tendinopathy. METHODS: Two observers examined the degree of Doppler flow independently using SAQ and the modified Öhberg score during a single consultation. The intraclass correlation coefficient, standard error of measurement, and minimal detectable difference were determined to evaluate the reliability and measurement properties of the SAQ method and the modified Öhberg score. RESULTS: In total, 28 consecutive patients with chronic midportion Achilles tendinopathy participated. The intraclass correlation coefficient for interobserver reliability of the SAQ method was 0.81 (95% confidence interval, 0.58-0.91), compared to 0.64 (95% confidence interval, 0.45-0.81) for the modified Öhberg score. The standard error of measurement and minimal detectable difference values for the SAQ method were 2.9% and 8.0%, respectively, and for the modified Öhberg score, they were 0.55 and 1.53 points. CONCLUSIONS: The SAQ method shows good reliability to evaluate the degree of Doppler flow in patients with chronic midportion Achilles tendinopathy, and it overcome

Effectiveness of a high volume injection as treatment for chronic Achilles tendinopathy

Objective To study whether a high volume injection without corticosteroids improves clinical outcome in addition to usual care for adults with chronic midportion Achilles tendinopathy. Design Patient and assessor blinded, placebo controlled randomised clinical trial. Setting Sports medicine department of a large district general hospital, the Netherlands. Participants 80 adults (aged 18-70 years) with clinically diagnosed chronic midportion Achilles tendinopathy and neovascula

Isometric exercises do not provide immediate pain relief in Achilles tendinopathy

Background: Isometric exercises may provide an immediate analgesic effect in patients with lower-limb tendinopathy and have been proposed as initial treatment and for immediate pain relief. Current evidence is conflicting, and previous studies were small. Objective: To study whether isometric exercises result in an immediate analgesic effect in patients with chronic midportion Achilles tendinopathy. Methods: Patients with clinically diagnosed chronic midportion Achilles tendinopathy were quasi-randomized to one of four arms: isometric calf-muscle exercises (tiptoes), isometric calf-muscle exercises (dorsiflexed ankle position), isotonic calf-muscle exercises, or rest. The primary outcome was pain measured on a visual analogue scale (VAS) score (0-100) during a functional task (10 unilateral hops) both before and after the intervention. Between-group differences were analyzed using a generalized estimation equations model. Results: We included 91 patients. There was no significant reduction in pain on the 10 hop test after performing any of the four interventions: isometric (tiptoes) group 0.2, 95%CI −11.2 to 11.5; isometric (dorsiflexed) group −1.9, 95%CI −13.6 to 9.7; isotonic group 1.4, 95%CI −8.3 to 11.1; and rest group 7.2, 95%CI −2.4 to 16.7. There were also no between-group differences after the interventions. Conclusion: The isometric exercises investigated in this study did not result in immediate analgesic benefit in patients with chronic midportion Achilles tendinopathy. We do not recommend isometric exercises if the aim is providing immediate pain relief. Future research should focus on the use of isometric or isotonic exercise therapy as initial treatment as all exercise protocols used in this study were well-tolerated

The STAP-study: The (cost) effectiveness of custom made orthotic insoles in the treatment for plantar fasciopathy in general practice and sports medicine: Design of a randomized controlled trial

Background: Plantar fasciopathy is a common cause of foot pain, accounting for 11 to 15 % of all foot symptoms requiring professional care in adults. Although many patients have complete resolution of symptoms within 12 months, many patients wish to reduce this period as much as possible. Orthotic devices are a frequently applied option of treatment in daily practice, despite a lack of evidence on the effectiveness. Therefore, the objective is to study the (cost)-effectiveness of custom made insoles by a podiatrist, compared to placebo insoles and usual care in patients with plantar fasciopathy in general practice and sports medicine clinics. Method/design: This study is a multi-center three-armed participant and assessor-blinded randomized controlled trial with 6-months follow-up. Patients with plantar fasciopathy, with a minimum duration of complaints of 2 weeks and aged between 18 and 65, who visit their general practitioner or sport physician are eligible for inclusion. A total of 185 patients will be randomized into three parallel groups. One group will receive usual care by the general practitioner or sports physician alone, one group will be referred to a podiatrist and will receive a custom made insole, and one group will be referred to a podiatrist and will receive a placebo insole. The primary outcome will be the change from baseline to 12 weeks follow-up in pain severity at rest and during activity on a 0-10 numerical rating scale (NRS). Secondary outcomes include foot function (according to the F
