HEIGHT CHANGES AMONG CHRONIC LOW-BACK-PAIN PATIENTS DURING INTENSE PHYSICAL EXERCISE

The possible effects of intense physical exercise on the total body st ature of low back pain patients were monitored by circadian total body height measurements. The height was measured with a statiometer, and the change in height was correlated with the changes in the range of m otion, pain and subjective disability and degree of disc degeneration seen on magnetic resonance imaging (MRI) pictures. The stature of 24 l ow back pain patients was measured during a 3-week period. There was a n increase of about 3 mm in height after only 4 days of exercise, and by the end of the programme the morning height increased on average by 7.2 mm. There were also 12 non-rehabilitated low back pain patients b ut no such increase was noted among them. The gain of height and reduc tion of pain were found to be statistically significantly correlated ( P=0.0001, r=-0.41), as did the gain of height and the decrease of back disability (Oswestry index) (P<0.0001, r=-0.39). Circadian total heig ht measures but not the MR images will change due to the active back r ehabilitation programme.
