Spinal effects of head-down tilting. Part 1--Low back contour changes.

The purpose of this study was to compare the effects of two methods of inversion therapy and four common exercise positions on the shape of the low back. We studied 25 healthy subjects in six exercise positions: 1) inverted with lower limbs extended (ILLE), 2) standing, 3) supine, 4) inverted with lower limbs flexed (ILLF), 5) sitting, and 6) hooklying. A manual measurement system was used to determine low back contours (LBCs) from S2 upward for 19 cm at 1-cm intervals. Contour data were reduced to mean contour values (MCVs). Results showed that the standing and sitting positions produced the largest and smallest MCVs, respectively (p less than .01). The ILLF MCV was smaller (p less than .05) than both supine MCVs but not appreciably different from the ILLE MCV. The ILLE and ILLF positions significantly reduced (p less than .01) MCVs compared with the standing position. Neither position decreased the MCV as much as the sitting position. These results support the use of inversion therapy to reduce the depth of the LBC when sitting is inappropriate.

Inverted spinal traction.

The effect of inverted positioning on spinal length and electromyographic (emg) activity of superficial lumbar area musculature was investigated in 20 healthy men. Spinal length tape measurements were taken with subjects first sitting erect and after 1 minute in the inverted position. An integrated bioelectric monitoring system was used to quantify emg activity. Initially, a stable emg baseline was identified for each subject resting supine on a motorized tilt table. The randomly selected control group subjects remained supine for an additional 245 seconds. Experimental group subjects were inverted for half this duration and returned to the resting position for the remainder. Data were recorded for 10-second accumulation periods of emg activity 16 times from each subject. The 1-tailed paired t-test was applied to all data. The difference between the means of the spinal length measurements taken sitting and during inversion was highly significant (p less than 0.005). The difference between the mean emg activity of the inversion period and the baseline mean was also statistically relevant (p less than 0.03). This study concluded that inverted positioning for short periods significantly increased spinal length and reduced emg activity of the superficial lumbar area musculature of normal males. These findings complemented the clinical observations of several authors.
