Original sentence: Chiropractors who still insist that all diseases stem from spinal misalignments ("subluxations"), and can therefore be cured by joint manipulation, remain open to charges of pseudoscience.However, medical scientists remain dubious about the underlying rationale for chiropractic.Sampson and Beyerstein (1996), state that "Many scientifically trained physicians accept that chiropractic manipulations could be beneficial for certain purely musculoskeletal complaints.The same is true of the many chiropractors who continue to reject the germ theory of disease, oppose basic immunization, and use scientifically discredited diagnostic devices"
