Results

Two persons dropped out because of continued use of oestrogen, which after initial confirmation they were nevertheless not willing to discontinue. Three were not menopausal according to the blood test, and one was on steroid therapy (connective tissue disease), in spite of a negation of this in the questionnaire. One dropped out half way through the study because of recurrent airway infections.

The remaining 11 women completed all the sessions. For those who completed, the study age ranged from 43 to 58 years (median 52), time since menopause ranged from 0 to 7 years (median 4), time since spinal cord lesion ranged from 3 to 49 years (median 11). The patient characteristics are described in Table 1.

For the test–retest procedure the coefficients of variation in BMD were all less than 3.3% (median 1.3%).

BMD of the femoral neck and trochanter and of the tibia decreased by 7.6, 5.7 and 2.7%, respectively (P-values 0.17, 0.22 and 0.18). BMD of the spine decreased by 0.7% (P-value 0.54).

There were no differences in BMD values between groups, neither after stratifying the subjects in two subgroups according to time since lesion (subject 4 and 6–10 versus the rest, see Table 1) nor after stratification by Frankel grade (seven subjects with Frankel grade D and four subjects with grade A–C, see Table 1).

Over the period of 30 months, osteocalcine and alkaline phosphatase values increased by 36 and 8%, respectively (P-values 0.01 and 0.05). Urine calcium increased by 106% and urine hydroxyproline by 194% (P-values 0.51 and 0.61). The results are presented in Tables 2 and 3.
