The objectives of this study were to describe (1) coital positions adopted
by chronic back pain patients, (2) and to describe sexual function as asses
sed by Derogatis Inventory of Sexual Functioning (DISF), In addition, patie
nts were asked questions regarding effects of sexual intercourse on severit
y of pain, influence of pain over sexual functioning, and perceived factors
causing sexual problems. This is a subset (45 patients) of a larger study
(70 patients) describing sexual functioning. These 45 patients responded to
additional questions as described above. Mean age of the patients was 55.7
years (range 36-74 years). There were 40 male patients. Twenty-five patien
ts (56%) were married. Mean duration of pain was 145.2 months. Thirty-two p
atients (27 male and 5 female) were sexually active. Eighty-one percent of
male and 100% of female patients, who were sexually active, preferred "male
superior" position. Of those sexually active, 41% performed sexual interco
urse while sitting on a chair. A majority of patients were experiencing pro
blems in all domains of sexual functioning except for fantasy. Thirty-nine
patients (87%) reported that pain extremely interfered in performing sexual
intercourse. Twenty-nine patients (64%) reported worsening of pain due to
sexual intercourse. Majority (n = 34) of the patients (76%) had fear of fai
lure to perform and 25 patients (56%) reported fear of aggravating pain due
to sexual activity. There is need for further research in this area.
