A Cochrane review in 2002 showed some benefits of the electrical stimulation as a rehabilitation intervention to improve the power of the hand grip and help to resist fatigue. D‐penicillamine may provide similar benefits as DMARDs but it is also highly toxic. Low-quality evidence suggests the use of therapeutic ultrasound on arthritic hands. Potential benefits include increased grip strength, reduced morning stiffness and number of swollen joints. There is tentative evidence of benefit of transcutaneous electrical nerve stimulation (TENS) in RA. Acupuncture‐like TENS (AL-TENS) may decrease pain intensity and improve muscle power scores.
