Jansen was hardworking, well liked by his colleagues, upright and helpful as a chief, and enjoyed teaching. His primary interest was rheumatology, and he wrote a physiotherapy textbook. He promoted the establishment of a Rheumatology Sanatorium at Skælskør (Andelsforeningernes Gigtsanatorium) supported by the Cooperative Societies, advised the planning of the Institute of Physiotherapy at the Karolinska Sjukhuset, Stockholm, and represented Denmark in the Ligue internationale contre le rheumatisme (now called the International League Against Rheumatism – ILAR).
