Induced movement in a patient is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator indicating that a valid stimulation has occurred so that the operator may adjust the stimulation accordingly. A search algorithm may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector is used or, alternatively, the motion detector is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus. Other signals indicative of motor threshold may be detected and correlated to the TMS stimulus pulses. For example, left / right asymmetry changes in a narrow subset of EEG leads placed on the forehead of the patient or fast autonomic responses, such as skin conductivity, modulation of respiration, reflex responses, and the like, may be detected. The appropriate stimulation level for TMS studies are also determined using techniques other than motor cortex motor threshold methods. For example, a localized ultrasound probe may be used to determine the depth of cortical tissue at the treatment site. When considered along with neuronal excitability, the stimulation level for treatment may be determined. Alternatively, a localized impedance probe or coil and detection circuit whose Q factor changes with tissue loading may be used to detect cortical depth.

This procedure consists in the first stage, of the administration of enough quantity of bisphosphonate preparation during the necessary period of time to acquire a degree of volumetric mineral density of the cortical tissue of application, within the normal range (average.±.1 DS). Then the administration of the bisphosphonate preparation is interrupted in order to enable the development of the sectional momentum of inertia. The length of the second stage can be determined by means of a tomography. That is to say, that the periods of administration or non-administration of the mineralizing agent are defined or controlled by precise osteologic variables and therefore are not fixed. If during the second stage the cortical mineral density drops by 6-10% of the maximum value previously obtained, administration of bishphosphonate preparation should be resumed until the corresponding maximum adjusted value is reached again. The proposed procedure of a period with bisphosphonate followed by another period without the bisphosphonate agent improves fracture resistance, provided that the length of both periods is controlled by defined osteologic variables.
