OBJECTIVE: To analyze the clinical significance of postoperative back muscle
exercises after percutaneous vertebroplasty for spinal osteoporotic compression
fracture patients. DESIGN: Clinical randomized controlled trials of parallel
group nonpharmacologic study. SETTING: Patients practised back muscle exercises
in the spinal surgery department, rehabilitation department and at their residences. SUBJECTS: Osteoporotic compression fracture patients who had
undergone percutaneous vertebroplasty and processed sufficient muscle strength to
participate in the training were studied. INTERVENTIONS: Patients were randomized
into two groups, which were titled A and B. General postoperation therapy,
including antiosteoporotic medications and education, was offered to all
patients. Group B patients received additional systematic back muscle exercise.
MAIN MEASURES: Both Oswestry Disability Index (ODI) and visual analogue scale
(VAS) were recorded preoperatively and postoperatively at three-day, one-month,
six-month, one-year and two-year follow-up. RESULTS: From January 2006 to January
2009, a total of 82 patients were assessed for eligibility, 60 patients were
enrolled and randomized into two groups. Forty-two (70%) patients (20 of 30 in
Group A and 22 of 30 in Group B) were successfully followed-up for two years.
Systematic back muscle exercises resulted in a significant advantage in both
measurements. The ODI of Group B was significantly better than Group A at the
six-month, one-year and two-year follow-ups (P < 0.05). The pain level of Group B
was significantly lower than in Group A at the one- and two-year follow-ups (P <
0.05). At the end of our study, the mean (SD) of the ODI in Groups A and B were
39.1 (9.14) and 23.4 (5.62); the mean (SD) of the VAS in Groups A and B were 3.4
(1.15) and 2.1 (0.84), respectively. CONCLUSIONS:
Our findings suggest that the
benefit of the exercises required at least six months to be observed; however,
the favourable effects could last for two years. Therefore, systematic back
muscle exercise should be recommended as one of the treatment guidelines for
postpercutaneous vertebroplasty patients.
