The present invention provides new evidences to support that repetitive peripheral magnetic stimulation (theta-burst en stimulation, TBS) over nerve/muscle improves sensorimotor control. Chronic low back pain (CLBP) is associated to a faulty volitional activation of transversus abdominis muscle (TrA) and its delayed contraction during anticipatory postural adjustment (APA), in correlation with maladaptive reorganization of primary motor cortex (M1). Repetitive magnetic stimulation of nerves can influence brain excitability and even reduce rigidity (Parkinsons disease), spasticity (stroke, ABI, cerebral palsy), and contribute to improvement of motor-control and function in stroke, chronic low back pain, ABI, cerebral palsy, prematurity and Parkinsons disease. We hereby test—for the first time—the after-effects of TBS applied over nerves or muscles (peripheral TBS, PTBS) on the motor abdominal-function of chronic low back pain sufferers and on the foot function of brain-injured subjects and to adjust TBS protocol per subject relative to the clinical profile. These pilot studies demonstrate the long-term influence of peripheral neurostimulation in chronic pain, rigidity and spasticity associated to motor impairment.
