Physical therapies refer to non-medical treatment strategies, including surgery, cryotherapy, UV phototherapy, and acupuncture. Most physical approaches are inappropriate in the context of itch. UV phototherapy and acupuncture may be effective in the management of itch. A literature search was performed using MEDLINE and EMBASE. Bibliographies were reviewed for relevant articles. Narrowband UVB (311-313 nm) and UVA1 (340-400 nm) are equally effective in managing atopic dermatitis and associated itch. The efficacy of broadband UVB in reducing uraemic itch has been demonstrated in a series of randomised controlled trials, but more recent studies have failed to reproduce these results. Non-randomised, uncontrolled studies and case series suggest that UV is effective in managing itch associated with cholestasis, chronic urticaria, prurigo, cutaneous T-cell lymphoma, aquagenic itch, and scleroderma. UV phototherapy is well tolerated, and no significant relationship between UVB therapy and skin cancer has been found. Experimentally, acupuncture has been shown to reduce allergen-related itch, although this finding has been limited by the small number of studies, inconsistency in agreement on acupuncture sites and study design, small sample sizes, and limited follow-up. UV phototherapy is an effective treatment for itch associated with atopic dermatitis. UVB may be effective in managing itch associated with end-stage kidney disease, cholestasis, chronic urticaria, prurigo, cutaneous T-cell lymphoma, aquagenic itch, and scleroderma. Phototherapy should be combined with standard first-line therapies. Insufficient evidence exists to justify acupuncture as a physical therapy for itch. Further well-designed studies are required to establish the effectiveness of physical therapies in managing itch.
