The aims of the presented study were to validate tools evaluating physical functioning (PF) after allogeneic hematopoietic stem cell transplantation (alloHSCT) and to analyze the impact of the clinical course on PF. Forty patients undergoing alloHSCT were enrolled in a prospective trial which included evaluation of muscle strength (grip test, CITEC dynamometer), endurance (2-min walk test), anxiety and depression (Hospital Anxiety and Depression Scale), fatigue (Modified Fatigue Impact Scale and Brief Fatigue Inventory), and physical activity (Human Activity Profile-HAP) before (t1) and 1 (t2) and 3 (t3) months after alloHSCT. At t2, all patients showed a 6 % (p = 0.02) loss of muscle strength which was higher in patients with acute graft-versus-host disease (aGVHD) (12 %). While patients without aGVHD recovered at t3, the loss of muscle strength was progressive in patients with aGVHD. The grip test results correlated with the results of detailed measurement of muscle strength by CITEC dynamometer (r = 0.4-0.8, p = 0.05-0.001). Moreover, the HAP scores correlated with physical performance. The results demonstrate that loss of PF occurs during the first month followed by a regain during the subsequent 2 months in the absence of aGVHD. The HAP and the grip test may serve as surrogate marker for the strength loss in the course of aGVHD.
