Aim of study (acc. to author)

Report of a clinical trial on treatment of osteoporosis with low frequency magnetic fields.

Background/further details

52 patients were selected on the basis of age, anamnesis, clinical symptoms and radiographic and mineralometric determinations.

Endpoint

Exposure

Exposure Parameters
Exposure 1: 50 Hz
Exposure duration: continuous for 30 min per day over 1 month; three times a year

Exposure 1

Main characteristics
Frequency 50 Hz
Type
Waveform
Exposure duration continuous for 30 min per day over 1 month; three times a year
Exposure setup
Exposure source
Setup The generator of the solenoidal field (60 cm diameter) run along the major axis of the patient's bed.
Parameters
Measurand Value Type Method Mass Remarks
magnetic flux density 5 mT minimum - - when early analgic effect expected
magnetic flux density 3 mT minimum - - 3-4 mT for causal treatment

Main outcome of study (acc. to author)

Positive results on pain and functionality with a global improvement in motor activity were obtained in 80-90% of the cases after the first or second cycle; a third cycle seemed to be indicated to stabilize early results. The demineralization process did not get worse (steady state level in the loss of bone tissue).
