Feasibility study of short-term effects of chiropractic manipulation on older adults with impaired balance

Objective: The purpose of this study was to collect preliminary information on the effects of chiropractic spinal manipulation on reducing risk of falls in older adults with impaired balance, as assessed by the Berg Balance Scale (BBS). This information is necessary to develop a line of investigation into the role of chiropractic care on reduction of fall risk in this population. Methods: Randomized, 2-group pretest/posttest design feasibility study with a target sample size of 10 (5 per group), conducted within the outpatient health center of a chiropractic college. Inclusion criteria were as follows: aged 60 years or older, able to stand on one leg < 5 seconds, and able to attend all sessions. Patients were assigned to chiropractic care (CMT) or supervised exercise (EX) and scheduled for 2 visits per week for 8 weeks. Results: A total of 26 people responded to recruitment; and 11 were enrolled: 6 in the CMT and 5 in the EX group. Two patients dropped out at the baseline visit when they were assigned to the EX group. One CMT patient dropped out in the seventh week because of a fall at home resulting in a leg fracture. All remaining patients were compliant with treatment protocols. Five of 6 CMT patients and 4 of 5 EX patients had baseline BBS scores < 45, indicating increased risk of falls. At visit 16, 2 CMT and 1 of the 3 remaining EX patients had BBS scores < 45. One mild and transient adverse event was noted. Conclusion: Further investigation of the possible role of chiropractic care in reducing fall risk in this population appears feasible. (C) 2007 National University of Health Sciences.
