A Review of Therapeutic Ultrasound: Biophysical Effects

Abstract: Almost 2 decades ago, it was pointed out that physical therapists tended to overlook the tenuous nature of the scientific basis for the use of therapeutic ultrasound. The purpose of this review is to examine the literature regarding the biophysical effects of therapeutic ultrasound to determine whether these effects may be considered sufficient to provide a reason (biological rationale) for the use of insonation for the treatment of people with pain and soft tissue injury. This review does not discuss articles that examined the clinical usefulness of ultrasound (see article by Robertson and Baker titled “A Review of Therapeutic Ultrasound: Effectiveness Studies” in this issue). The frequently described biophysical effects of ultrasound either do not occur in vivo under therapeutic conditions or have not been proven to have a clinical effect under these conditions. This review reveals that there is currently insufficient biophysical evidence to provide a scientific foundation for the clinical use of therapeutic ultrasound for the treatment of people with pain and soft tissue injury.

Extended single-mode photonic crystal fiber lasers

Abstract: We report on an ytterbium-doped photonic crystal fiber with a core diameter of 60 μm and mode-field-area of ~2000 μm2 of the emitted fundamental mode. Together with the short absorption length of 0.5 m this fiber possesses a record low nonlinearity which makes this fiber predestinated for the amplification of short laser pulses to very high peak powers. In a first continuous-wave experiment a power of 320 W has been extracted corresponding to 550 W per meter. To our knowledge this represents the highest power per unit length ever reported for fiber lasers. Furthermore, the robust single-transverse-mode propagation in a passive 100 μm core fiber with a similar design reveals the potential of extended large-mode-area photonic crystal fibers.

Formal, Nonformal and Informal Coach Learning: A Holistic Conceptualisation

Abstract: Using Coombs and Ahmed's framework of formal, non-formal, and informal learning as the analytical framework, this paper aims to review and conceptually locate literature exploring how sports coaches acquire the knowledge that underpins their professional practice. Furthermore, in an attempt to develop a robust set of accessible terms and concepts this paper identifies, explores and positions various terminologies under the broader heading of coach learning. It was hoped that this conceptual review would not only stimulate discussion and research into coach learning, but that it would also promote the construction of models of how coaches currently learn, as well as models for enhancing coach learning. The paper concludes that coaches learn from a wide range of sources, but formalised (i.e., formal and nonformal) learning episodes were found to be relatively low impact endeavours when compared to informal, self-directed modes of learning.
