    Notes: Ultrasonic speckle velocimetry (USV) was recently introduced as a new ultrafast tool for measuring fluid velocities in two dimensions by analyzing the speckle signal backscattered from particles moving with the flow [Sandrin et al., Appl. Phys. Lett. 78, 1155 (2001)]. An experimental study of a stationary stretched vortex is presented, which demonstrates the efficiency of ultrafast 2D USV in terms of quantitative assessment of vortical flows. The full velocity field is recovered and compared to the Burgers model for two different fluids: water and milk. The dependence of the vortex characteristics on the main control parameter is investigated. © 2001 American Institute of Physics.

    Notes: summary  The aim of this evaluation was to examine correlations between internal derangement of the temporomandibular joint (TMJ) and cervical spine disorder (CSD). A prospective controlled clinical study was carried out. Thirty patients with signs and symptoms of internal derangement but without any subjective neck problems and 30 age- and gender-matched control subjects without signs and symptoms of internal derangement were examined. The investigation of the temporomandibular system was carried out using a ‘Craniomandibular Index’. Afterwards an examiner-blinded manual medical investigation of the craniocervical system was performed. This included muscle palpation of the cervical spine and shoulder girdle as well as passive movement tests of the cervical spine, to detect restrictions in the range of movement as well as segmental intervertebral dysfunction. The internal derangement of the TMJ was significantly associated with ‘silent’ CSD (t-test, P 〈 0ḃ05). Patients with raised muscle tenderness of the temporomandibular system exhibited significantly more often pain on pressure of the neck muscles than patients without muscle tenderness of the temporomandibular system (t-test, P 〈 0ḃ05). As a result of the present study, for patients with internal derangement of the TMJ an additional examination of the craniocervical system should be recommended.

    Description / Table of Contents: Summary Objectives: The effectiveness of acupuncture treatment in patients with osteoarthritis of the hip was tested. ¶Design: This is a prospective, randomized, controlled patient and examiner blinded clinical trial. ¶Patients and setting: The study was performed at a university department for physical medicine and rehabilitation. Sixty-seven patients were separated into two treatment groups. ¶Interventions: Group 1 (treatment) had traditional needle placement and manipulation, whereas in group 2 (control) needles were placed away from classic positions and not manipulated. In both groups needles were placed within the L2 to L5 dermatomes. Endpoints were pain (VAS), functional impairment (hip score), activity of daily living (ADL) and overall satisfaction before treatment, 2 weeks and 2 months post-intervention. ¶Results: For all endpoints there was a significant improvement in both groups 2 weeks and 2 months following treatment versus baseline, but no significant difference between the two treatment groups. ¶Conclusions: We conclude from these results that needle placement in the area of the affected hip by itself improves symptoms of osteoarthritis. It appears to be less important to follow the rules of traditional acupuncture techniques.
    Notes: Zusammenfassung Fragestellung: Die klinische Wirksamkeit der Akupunktur ist umstritten. Trotz zunehmender Akzeptanz bei westlichen Ärzten und Patienten mangelt es an kontrollierten Wirksamkeitsnachweisen. Die klinische Wirksamkeit einer gezielten Nadelakupunktur wurde am Beispiel der Koxarthrose untersucht. ¶Design: In einer prospektiven, randomisierten, placebokontrollierten, patienten- und untersucherblinden Studie wurde erstmals die Wirksamkeit einer gezielten Akupunktur bei Koxarthrose überprüft. Es wurden 67 Patienten in die Studie aufgenommen, auf zwei Behandlungsgruppen verteilt und in 3 Wochen 9-mal behandelt. ¶Intervention: Die Akupunkturbehandlung richtete sich nach den Empfehlungen der Traditionell Chinesischen Akupunktur. Als Kontrollbehandlung wurde eine modifizierte Minimal-Akupunktur n. Vincent verwendet. ¶Zielparameter: Schmerzintensität (VAS), Hüftfunktionsindex n. Lequesne, Activity of daily living, ADL n. Bullinger, over-all-assessment n. Carlsson, ROM und radiologische Einteilung n. Kellgreen. ¶Ergebnisse: Zwei Wochen sowie zwei Monate nach der Behandlung zeigte sich in beiden Behandlungsgruppen eine signifikante Besserung der Beschwerden (p〈0,0005). Die Schmerzreduktion betrug im Mittel 27%, der Hüftfunktionsindex besserte sich um 18% und die Lebensqualität um 5%. Zwischen den beiden Behandlungen waren keine signifikanten Wirkunterschiede nachweisbar. Insgesamt profitierten etwa 50% der Patienten sowohl von der Verum-Akupunktur als auch von der Kontroll-Akupunktur.¶Schlussfolgerung: Die Ergebnisse legen den Schluss nahe, dass für den schmerzdämpfenden Effekt einer Nadelakupuntur zur Behandlung der Koxarthrose die lokale Behandlung mit Akupunktur ausreichend ist, wobei für die Durchführung der Akupunktur keine speziellen Akupunkturkenntnisse der Chinesischen Medizin nötig sind.
