A double-blind study of Grenz ray therapy in chronic eczema of the hands.

The effect of Grenz ray therapy as an adjunct to topical therapy in chronic symmetrical eczema of the hands was assessed in 24 patients by randomly allocating active treatment to one hand while the other, which received simulated therapy, served as a control. Three Gy of Grenz rays were applied on six occasions at intervals of 1 week. There was a significantly better response to active treatment 5 and 10 weeks after the start of treatment compared with the untreated control.
