Plasma IL-6 before and 20 min after prolonged muscular exercise for 20 min at the individual aerobic/anaerobic threshold was analyzed in patients with neuromuscular diseases and in controls. Patients were assigned to the following diagnostic categories: Controls (n=18); amyotrophic lateral sclerosis (n=7); peripheral neuropathy (n=6); muscular dystrophy (n=13); mitochondriopathy (n=3); myopathy (others) (n=3); inflammatory myopathy (n=6); mononeuropathy (n=4). The concentrations of IL-6 before exercise were 5.55+/-0.94 pg/ml, and 6.52+/-0.97 pg/ml after exercise (P=0.0001). We introduced the independent variables age, sex and diagnostic category into a stepwise multiple linear regression model. Age emerged as a significant predictor of the IL-6 ratio (IL-6 post exercise/lL-6 before exercise). The regression equation was: IL-6 ratio=0.87+0.009xage (years), R=0.33, P<0.01, simple linear regression model. All IL-1beta concentrations were below the sensitivity of the assay (5 pg/ml). Concerning patients with neuromuscular diseases, the age associated increased IL-6 release after exercise could mean additional muscle damage.

We have measured concentrations of 26 serum amino acids in 46 subjects (aged 17-75 years), with the following neurological diseases: amyotrophic lateral sclerosis, n=7; peripheral neuropathy, n=5; muscular dystrophy, n=7; mitochondriopathy, n=3; metabolic myopathy (others), n=2; inflammatory myopathy, n=4; mononeuropathy, n=3; controls (patients with symptoms suggesting neuromuscular system dysfunction without objective evidence of neuromuscular disease), n=15, before and after prolonged muscular effort. Tests were done on a bicycle ergometer at the individual aerobic/anaerobic threshold determined for each subject in preliminary tests. Using a stepwise multiple linear regression model, age emerged as a significant negative predictor (P<0.05) of the post/before ratio of the levels of five amino acids. We conclude that an increase in recovery time and a reduction in training capacity with aging could be linked to these changes. The cause is assumed to be principally a reduction in glycogen storage in muscle with increasing age; this situation could possibly be improved by consumption of carbohydrate before or during exercise, or also during rehabilitation exercise or training in neuromuscular or other diseases.

The posterior tibial tendon transfer through the interosseous membrane, as popularized by Watkins in 1954, is a procedure for treating reducible eversion and dorsiflexory paresis used by lower extremity foot and ankle surgeons. The posterior tibial tendon has been transferred to various locations on the midfoot for equinus and equinovarus deformities. Dorsiflexory paresis is a common symptom in equinovarus deformity, clubfoot deformity, Charcot-Marie-Tooth disease, leprosy, mononeuropathy, trauma to the common peroneal nerve, cerebrovascular accident, and Duchenne's muscular dystrophy. The main difficulty with this procedure, often discussed by surgeons, is inadequate tendon length, making anchoring to the cuneiforms or cuboid difficult. The goal of our cadaveric study was threefold. First, we sought to determine whether the tendon length is sufficient when transferring the posterior tibial tendon to the dorsum of the foot through the interosseous membrane for a dynamic or a static transfer. Second, we wished to describe the surgical technique designed to obtain the maximal length. Finally, we sought to discuss the strategies used when the tendon length for transfer is insufficient.
