Randomized Controlled Trial
Effects of transcutaneous electrical nerve stimulation on pain, pain sensitivity, and function in people with knee osteoarthritis: a randomized controlled trial.
Transcutaneous electrical nerve stimulation (TENS) is commonly used for the management of pain; however, its effects on several pain and function measures are unclear. ⋯ Both HF-TENS and LF-TENS increased PPT in people with knee osteoarthritis; placebo TENS had no significant effect on PPT. Cutaneous pain measures were unaffected by TENS. Subjective pain ratings at rest and during movement were similarly reduced by active TENS and placebo TENS, suggesting a strong placebo component of the effect of TENS.

Randomized Controlled Trial
Effects of interferential therapy parameter combinations upon experimentally induced pain in pain-free participants: a randomized controlled trial.
Little evidence exists regarding parameter selection for hypoalgesia using interferential therapy (IFT). ⋯ This study showed that IFT delivered at high, to-tolerance intensity and high AMF does not produce significant segmental and extrasegmental hypoalgesic effects on PPT in participants who were healthy compared with a control or placebo group. Further research is warranted to investigate the hypoalgesic effect of different IFT parameter combinations and to explain its possible mechanism of action.

Randomized Controlled Trial
Can supervised group exercises including ergonomic advice reduce the prevalence and severity of low back pain and pelvic girdle pain in pregnancy? A randomized controlled trial.
Many women have low back pain (LBP) or pelvic girdle pain (PGP) during pregnancy, but there is limited evidence of effective primary and secondary preventive strategies. ⋯ Supervised group exercise did not reduce the prevalence of LBP or PGP in pregnancy.

Respiratory muscle training promotes weaning in patients who are dependent on mechanical ventilation. Respiratory muscles can be trained using linear inspiratory-resistive loads to improve their strength and endurance. The purpose of this case report is to demonstrate that a therapeutic intervention consisting of a linear pressure load device facilitates ventilator weaning in an infant who is chronically ventilated. ⋯ This case report describes respiratory muscle training using a linear pressure load device to successfully wean an infant from mechanical ventilation. However, well-controlled clinical trials are necessary to better understand the effects of this intervention on neonatal respiratory muscles.

Direct access to physical therapist services is permitted by law in the majority of states and across all practice settings. Ohio enacted such legislation in 2004; however, it was unknown how direct access had affected actual clinical practice. ⋯ Implementation of a direct access physical therapist practice model is evident in Ohio. Factors related to reimbursement and organizational policy appear to impede the process.
