Comprehensive rehabilitation of patients having chronic low back pain

Seventy-two patients having chronic back pain, representative of high-risk demographic and personality populations, received a broad range of therapeutic modalities designed around the theme of self-regulation. The self-regulation principle was used in: (1) biofeedback training for teaching self-regulated muscle relaxation; (2) psychological counseling emphasizing self-control techniques for the management of stress and anxiety, including assertion training; (3) patient-regulated medication program; (4) patient involved case conferences; (5) physical therapy program emphasizing reconditoning; (6) comprehensive vocational rehabilitation services; (7) a series of educational lectures; (8) a therapeutic milieu designed for relaxation, recreation and socialization. Utilizing a success criteria of functional physical activity at discharge (average length of stay, 45 days) and levels of vocational restoration (employable, in training, or employed at 30 days postdischarge), 57 of the patients demonstrated unimpaired physical functioning levels and 59 of the patients were at success levels of vocational restoration.

Role of a muscle target organ on the regeneration of motor nerve fibres in long nerve grafts: a synopsis of experimental and clinical data

The importance of the muscle target organ as a promoting factor for nerve fibre regeneration in nerve grafts is still a subject of controversial discussion. In the last few years we published uniform results of experimental series in sheep and rabbits in which we investigated the biology of nerve fibre regeneration in long nerve autografts without connection to a target organ. Surprisingly, we found excellent regeneration of myelinated nerve fibres without the influence of a target organ through the whole length of the nerve graft, with an increase in the number of nerve fibres up to fourfold at the distal end. In the sheep series the additional contact with a muscle target organ for 6 months had a variable effect on the fibre population in the distal end of the nerve graft. The results of our planimetric analyses of nerve biopsies in patients with facial paralysis, who were treated by cross-face nerve grafting and free muscle transplantation, are extremely divergent from the results of our experimental series. Instead of an increase, we found a decrease in number of regenerating nerve fibres arriving at the distal end of the cross-face nerve graft down to 20%. Species-specific differences in the biology of nerve regeneration are discussed, together with their implications for the complex clinical situation of nerve grafting with or without the influence of a target organ.
