Postmenopausal spinal osteoporosis: flexion versus extension exercises.

M Sinaki, B A Mikkelsen

    Archives of Physical Medicine and Rehabilitation
    |October 1, 1984
    PubMed
    Summary

    For postmenopausal osteoporosis, flexion exercises led to significantly more vertebral fractures than extension exercises. Extension or isometric exercises are recommended for managing spinal osteoporosis in women.

    Area of Science:

    • Gerontology
    • Orthopedics
    • Physical Therapy

    Background:

    • Postmenopausal osteoporosis is a significant health concern, increasing fracture risk.
    • Back pain is a common symptom associated with spinal osteoporosis.
    • Exercise therapy is a key component in managing osteoporosis, but exercise type may influence outcomes.

    Purpose of the Study:

    • To compare the efficacy of different exercise regimens in preventing further vertebral fractures in women with postmenopausal osteoporosis.
    • To determine if flexion or extension exercises impact fracture incidence differently.

    Main Methods:

    • A cohort of 59 women with postmenopausal spinal osteoporosis and back pain were assigned to four groups: extension exercises (E), flexion exercises (F), combined (E+F) exercises, or no exercises (N).

  • Spine x-ray studies were conducted before treatment and at follow-up (1-6 years).
  • Incidence of new wedging and compression fractures was recorded and compared between groups.

    • Main Results:

    • The flexion exercise group (F) had the highest incidence of new fractures (89%), followed by the no exercise group (N) (67%) and the combined group (E+F) (53%).
    • The extension exercise group (E) showed the lowest fracture incidence (16%).
    • Fracture occurrence was significantly higher in the flexion (p<0.001) and combined (p<0.01) groups compared to the extension group.

    Conclusions:

    • Flexion-based exercise programs are associated with a significantly higher risk of vertebral compression fractures in postmenopausal osteoporosis patients.
    • Extension or isometric exercises appear to be safer and more appropriate for managing spinal osteoporosis in this population.
    • Exercise selection is critical for preventing further skeletal damage in women with postmenopausal osteoporosis.
