Background. The health benefits associated with physical activity–based rehabilitation in patients with no lower-extremity motor function after a spinal cord injury (SCI) is uncertain. Methods. The authors assessed signs of efficacy, safety, and utility associated with a novel pharmacological combination therapy to activate central pattern generator (CPG) activity and corresponding locomotor activity in complete thoracic Th9/10-transected mice. Results. Subcutaneous administration 4 times per week for 1 month of 1.5 mg/kg buspirone, 1.5 mg/kg apomorphine, 12.5 mg/kg benserazide, and 50 mg/kg L-DOPA induced episodes of weight-bearing stepping on a treadmill in nonassisted paraplegic mice for 45-minute sessions. Hindlimb muscle cross-sectional area and fiber area values as well as several blood cell constituent levels assessed at 30 days postinjury were positively affected by the combination therapy, as compared with controls. Episodes of locomotion remained effective on each treatment. Femoral bone mineral density loss was not prevented by triple therapy. Conclusion. Although translation of these findings needs further experimentation, similar pharmacological activation of the CPG offers a novel therapeutic target to provide some health benefits in motor-complete SCI patients.

Effects of Co-Administration of Clenbuterol and Testosterone Propionate on Skeletal Muscle in Paraplegic Mice

Spinal cord injury (SCI) is generally associated with a rapid and significant decrease in muscle mass and corresponding changes in skeletal muscle properties. Although beta(2)-adrenergic and androgen receptor agonists are anabolic substances clearly shown to prevent or reverse muscle wasting in some pathological conditions, their effects in SCI patients remain largely unknown. Here we studied the effects of clenbuterol and testosterone propionate administered separately or in combination on skeletal muscle properties and adipose tissue in adult CD1 mice spinal-cord-transected (Tx) at the low-thoracic level (i.e., induced complete paraplegia). Administered shortly post-Tx, these substances were found to differentially reduce loss in body weight, muscle mass, and muscle fiber cross-sectional area (CSA) values. Although all three treatments induced significant effects, testosterone-treated animals were generally less protected against Tx-related changes. However, none of the treatments prevented fat tissue loss or muscle fiber type conversion and functional loss generally found in Tx animals. These results provide evidence suggesting that clenbuterol alone or combined with testosterone may constitute better clinically-relevant treatments than testosterone alone to decrease muscle atrophy (mass and fiber CSA) in SCI subjects.
