Southern California University of Health Sciences (SCU) researchers have received a half-million dollar National Institutes of Health (NIH) R15 grant to advance understanding of spinal manipulative therapy for neck pain. The grant is a two-year award study, with research work getting underway in January 2023. NIH R15 grants support small-scale research projects at educational institutions that provide baccalaureate or advanced degrees for a significant number of the nation's research scientists but that have not been major recipients of NIH support. The grant and study is a renewal and continuation of an ongoing study that was first funded by the NIH in 2018, during which SCU researchers were investigating patients with low back pain.
