A study conducted at "Naftalan" Special Hospital in Croatia evaluated the impact of naphtalanotherapy (NT) combined with individually tailored physiotherapy (ITP) on 119 patients with psoriatic arthritis and psoriasis. Patients underwent treatments for either two or three weeks. Results indicated that both treatment durations significantly improved pain, stiffness, swelling, disease activity, skin condition, and quality of life, with the three-week program proving more effective. The findings support the inclusion of NT and ITP in the management psoriatic disease and suggest that extended rehabilitation could have long-term benefits, potentially influencing health insurance policies.
