Randomized Controlled Trial
Is mechanical pain threshold after transcutaneous electrical nerve stimulation (TENS) increased locally and unilaterally? A randomized placebo-controlled trial in healthy subjects.
It is not fully understood how transcutaneous electrical nerve stimulation (TENS) intensity affects mechanical pain threshold. ⋯ TENS administered at a strong but comfortable non-painful stimulation intensity increases mechanical pain threshold ipsi-laterally in healthy subjects, whereas TENS administered at sensory threshold intensity does not. TENS may be ineffective if electrodes are placed contralaterally or distant to the pain site and if stimulation intensity levels are not titrated to subjective strong levels. Further clinical trials are needed to clarify if these findings may also be generalized to populations of chronic pain sufferers.

Physiotherapists' use of research evidence with clinical decision-making has interested researchers world-wide since 1980; however, little is known about such practices in Australia. The present survey sought information on Australian physiotherapists' perceptions of the importance of research, and barriers to uptake of evidence in clinical practice, when compared with an international cohort from 2001. ⋯ The study identified constraints on uptake of evidence into practice that were related to accessing, reading and interpreting published research, and implementing findings. Found consistently across employment categories were barriers relating to lack of time, uncertainty about what the research reported, scepticism about the value of research and being isolated from peer support and literature sources. The responses indicated a positive shift towards evidence uptake since the 2001 NHS survey, suggesting an influence of increased exposure to information on evidence-based practice. A greater focus on research whilst training, the application of educational strategies for empowerment, better knowledge transfer and upskilling within the workplace, and ensuring dedicated time and organizational support for research activities are indicated.

Contemporary guidelines for the management of low back pain often consider patient involvement and responsibility an essential component; however, there has been little exploration of patients' opinions about back pain and its management. ⋯ In this group of participants with a history of back pain and physiotherapy treatment a common finding was a degree of acceptance of the back pain problem and the belief that patient involvement in management was essential. These findings would suggest that many patients with back pain may respond positively to the message of self-management. However, acceptance of this message was not automatic, but generally occurred gradually in line with patients' experience of back pain and treatment.

Fear-avoidance beliefs are important determinants for disability in patients with non-specific low-back pain (LBP). The association with self-reported level of physical activity is less known. The aim of the present study was to describe the level of physical activity in patients with chronic non-specific LBP and its relation to fear-avoidance beliefs and pain catastrophizing. ⋯ This study indicates that it seems important for physiotherapists in primary care to measure levels of fear-avoidance beliefs or pain catastrophizing. In particular, the two subscales of the TSK could be of real value for clinicians when making treatment decisions concerning physical exercise therapy for patients with chronic LBP.

Nosocomial infections present a widespread problem in today's healthcare environment, with a significant number of patients acquiring an infection annually. With the contemporary transition of immunocompromised and high-risk patients to community-based care, therapeutic ultrasound has the potential to be a vector of infection in the physiotherapy setting. The purpose of the present study was to determine the degree of contamination on therapeutic ultrasound transducer heads and ultrasound gel after routine clinical use, and to evaluate the efficacy of recommended infection control procedures. ⋯ Therapeutic ultrasound equipment is a potential vector for nosocomial infection in physiotherapy patients. The risk of infection from transducer heads can be effectively removed by cleaning with 70% alcohol between patients. Further research into possible strategies to reduce the risk of infection from ultrasound gels is needed.
