Randomized Controlled Trial
Relationship between intensity of quadriceps muscle neuromuscular electrical stimulation and strength recovery after total knee arthroplasty.
Neuromuscular electrical stimulation (NMES) can facilitate the recovery of quadriceps muscle strength after total knee arthroplasty (TKA), yet the optimal intensity (dosage) of NMES and its effect on strength after TKA have yet to be determined. ⋯ Higher NMES training intensities were associated with greater quadriceps muscle strength and activation after TKA.

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
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
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.

Randomized Controlled Trial Comparative Study
Effect of motor control exercises versus graded activity in patients with chronic nonspecific low back pain: a randomized controlled trial.
Motor control exercises to improve control and coordination of trunk muscles and graded activity under the principles of cognitive-behavioral therapy are 2 commonly used exercise therapies, yet there is little evidence to support the use of one intervention over the other. ⋯ results of this study suggest that motor control exercises and graded activity have similar effects for patients with chronic nonspecific low back pain.
