Input: Two studies (n of 80), where n is the number of participants, met the inclusion criteria. Ultrasound to the palmar and dorsal aspects of the hand significantly increased grip strength, measured as weighted mean difference (WMD) from control [WMD 28.07 (95 CI: 13.37 to 42.77)]. Ultrasound to the palmar and dorsal aspects of the hand also appeared to have beneficial effects on the following outcome measures: wrist dorsal flexion [WMD 1.90 (95%CI: 0.64 to 3.16)], duration of morning stiffness [WMD 28.54 (95%CI: 0.18 to 56.90)], number of swollen joints [WMD 1.02 (95%CI: 0.45 to 1.59)], and the number of painful joints [WMD 1.20 (95%CI: 0.45 to 1.95)]. There was no significant difference between a) exercises and wax baths, b) exercises with ultrasound, c) exercises with ultrasound and faradic hand baths on the outcome measures: pain score, grip strength, circumference of proximal interphalangeal (PIP) joints, articular index, and range of motion or level of activity. The reviewers concluded that ultrasound in combination with exercises, faradic current and wax bath treatment modalities is not supported and cannot be recommended. Ultrasound alone can, however, be used on the hand to increase grip strength, and to a lesser extent and based on borderline results, increase wrist dorsal flexion, decrease morning stiffness, reduce the number of swollen joints, and reduce the number of painful joints. It is important to note that these conclusions are limited by methodological considerations such as poor quality of the included trials, the low number of clinical trials, and the small number of study participants.
Output:

This review of two randomized trials (RCTs) showed that continuous ultrasound applied in water to the dorsal and palmar aspects of the hand increased grip strength as compared with placebo. This benefit was not evident with combined therapy (exercise, wax bath, faradic hand baths). Ultrasound also produced a borderline increase in wrist dorsal flexion, decreased morning stiffness, and reduced the number of swollen and painful joints. The conclusions are limited by few studies, small sample size and limitations in study methodology.
