ABSTRACT Background: In Duchenne muscular dystrophy (DMD) the increase of muscular fat content and fibrosis generates a reduction of range of motion (ROM) of the joints. Boys with DMD develop a disorganized body causing severe systemic consequences, especially after relying on a wheelchair. Classically, physical therapy contributes for prolongation of life and as a palliative care in late stage by respiratory management. However, it has never been tried to reduce contractures and deformations via fascia manipulation. Objective: To test the hypothesis that physical intervention through manual fascia stimulation may influence the range of motion (ROM) in boys with DMD. Methods: The TDFS Tridimensional Dynamic Fascial Stimulation was chosen, whose protocol is being tested in cycles of 10 sessions (3 mini-cycles of 3 plus one closure session; 90 minutes each). It proposes to reach simultaneously the musculoskeletal system, meningeal and visceral core. Two patients (male, 8yo, 1 ambulant, 1 wheel chair) received 6 weekly sessions; afterwards 1 patient (male, 9yo, wheel chair) received 20 weekly sessions. ROM was measured by a gravitational fleximeter: - before and after 6 sessions; - before, after 10, and after 20 sessions. Results: 6 sessions: a) ambulant – 24 movements in the girdles and limbs at each side, and 10 movements of the trunk (total 58): 33 movements (56,9%) increased, 20 (34,5%) decreased, and 5 (8,6%) maintained. b) wheel chair boy - same movements, except the 2 side bending of the trunk (total 56): 22 movements (39,3%) increased, 33 (58,9%) decreased, and 1 (1,8%) maintained. 20 sessions: – 18 movements in girdles and limbs at each side, and 01 (flexion) in the trunk (total 37): a) after 10 sessions: 19 (51,4%) increased, 10 (27%) decreased, and 8 (21,6%) maintained; b) after 20 sessions: 16 movements (43,2%) increased, 11 (29,7%) decreased, and 10 (27%) maintained. Discussion: Increases and decreases in ROM can be beneficial or not depending how the initial values are lower or higher than those of normal people. Trunk flexion increased and stabilized afterwards, while girdles and limbs changed both to more and less flexibility. Conclusion: The TDFS method was able to evoke changes of ROM towards more as well as less flexibility, both in the ambulant and the wheel chair DMD patients. Further research is needed to understand the details of appendicular ROM changes without treatment as well as those possibly induced by TDFS.
