Health related absenteeism costs an estimated $153 billion annually in the United States (Witters and Agrawal, 2011).   Chronic conditions (major contributors to absenteeism) are often successfully managed by Complementary and Alternative Medicine (CAM). As CAM becomes an increasingly visible component of healthcare, firms may wish to consider whether CAM therapies can help reduce illness-related absenteeism. This paper aims to extend the literature on healthcare utilization and absenteeism by exploring whether CAM treatment is associated with fewer workdays missed due to illness.

METHODS:   Using the 2007 National Health Interview Survey (NHIS) and propensity score matching (PSM), this study estimates the relationship between visits to CAM practitioners, health, and illness-related absenteeism.

RESULTS:   In a sample of 8,820 workers, the average annual number of workdays lost due to illness is 3.69. Visiting an acupuncturist correlates with lower absenteeism among men (1.182 fewer workdays missed, p<0.05), whereas visiting a naturopathic doctor correlates with 2.359 and 2.521 fewer workdays missed for women and men, respectively (both p<0.001). Active mind-body practices, massage, chiropractic and acupuncture treatments are all significantly associated with improved health.

INTRODUCTION:   Mechanoreceptor stimulation is theorized to contribute to the therapeutic efficacy of spinal manipulation. Use of mechanically-assisted spinal manipulation (MA-SM) devices is increasing among manual therapy clinicians worldwide. The purpose of this pilot study is to determine the feasibility of recording in vivo muscle spindle responses during a MA-SM in an intervertebral fixated animal model.

METHODS:   Intervertebral fixation was created by inserting facet screws through the left L5-6 and L6-7 facet joints of a cat spine. Three L6muscle spindle afferents with receptive fields in back muscles were isolated. Recordings were made during MA-SM thrusts delivered to the L7 spinous process using an instrumented Activator IV clinical device.

RESULTS:   Nine MA-SM thrusts were delivered with peak forces ranging from 68-122N and with thrust durations of less than 5ms. High frequency muscle spindle discharge occurred during MA-SM. Following the MA-SM, muscle spindle responses included returning to pre-manipulation levels, slightly decreasing for a short window of time, and greatly decreasing for more than 40s.
