Abstract
Background: De Quervain's tenosynovitis is a common cause of wrist pain in pregnant and postpartum females. This study provides objective evidence regarding the therapeutic efficacy of phonophoresis in treating de Quervain's disease during pregnancy.
Methods: In a single blind, randomised, controlled trial (n = 50), ketoprofen phonophoresis was given to the intervention group and conventional ultrasound (US) was given to controls, coupled with thumb splint immobilisation, and supervised strengthening and stretching exercises for 1 month. Symptomatic and functional improvement was assessed by visual pain analogue, grip, tip, key, and palmer pinch scales.
Results: There was a statistically significant improvement in the intervention group compared to the control group in grip and pinch strength, and pain reduction.
Conclusion: Ketoprofen phonophoresis as an adjunct to supervised exercise and splint immobilisation is a safe and effective therapy for de Quervain's tenosynovitis during pregnancy. Phonophoresis augments the benefits of US in terms of reducing pain and inflammation, and improving functional strength.
