Abstract The value of a program for the rehabilitation of osteoporotic patients (PRO) was assessed from a 4-year follow up of 139 patients referred to the program over its initial 2 years of operation. The program consisted of educational seminars, social activities and regular exercise supervision. Patients had annual clinical assessments, and bone mass measurements by neutron activation analysis (reported as CaBI). Fitness was assessed by performance on a treadmill (reported in terms of VO2 max, ml/kg/min). Seventy-eight of the 139 patients remained in the program over the 4-year follow-up. This unusually high level of commitment to the program is indicative of the psychological value that patients have derived from it. The effect of the program on the osteoporosis process was inconclusive. Group 2, the 37 patients who obtained the greatest improvement in fitness (VO 2max 〉6 ml/kg/min), had a significantly greater reduction in back pain than did group 1, the 36 with less significant improvement (VO 2max 〉6 ml/kg/min). The bone mass and incidence of vertebral fractures on entry into the program were not significantly different between the two groups. Group 2 had on average a greater increase in bone mass over the 4 years; mean increases in CaBI, (±SD) were 0.09±0.09 and 0.05±0.10 for groups 2 and 1 respectively. Group 2 had on average fewer new vertebral fractures (0.08±0.36 and 0.28±0.75 for groups 2 and 1 respectively). While these findings were encouraging, they did not reach significance at the 5% level (p=0.075 andp=0.09 for changes in CaBI and new vertebral fractures, respectively). A large randomized study would be required to establish clinical value quantitatively. Nevertheless, the qualitative benefit to patients is sufficiently impressive for a wider experience in rehabilitation programs to be encouraged.
