Abstract
AIM: The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with type 2 diabetes (DM). The impact of DM on mobility, balance, and management of BPPV is unknown. This prospective study compared symptom severity, mobility and balance before and after the canalith repositioning maneuver (CRM) in people with posterior canal BPPV canalithiasis, with and without DM.
METHODS: Fifty participants, BPPV (n=34) and BPPV+DM (n=16) were examined for symptom severity (dizziness handicap inventory, DHI), mobility (functional gait assessment, FGA), and postural sway (using an accelerometer in five conditions) before and after the CRM. The number of maneuvers required for symptom resolution was recorded.
RESULTS: At baseline, no differences in DHI or FGA scores were seen between groups, however, people with BPPV+DM had higher sway velocity in the medio-lateral direction in tandem stance (p<0.01). After treatment, both groups improved in DHI and FGA scores (p<0.01), with no differences between groups. Decrease in sway velocity in the mediolateral direction (p=0.003) were seen in tandem stance in persons with BPPV+DM. There were no differences between the groups in the number of CRMs provided.
CONCLUSIONS: This pilot study showed no differences in symptom severity, mobility deficits or efficacy of CRM treatments in people with posterior canal BPPV canalithiasis with and without DM. Future studies examining the impact of the severity and duration of diabetes, as well as the influence of diabetic peripheral neuropathy on functional performance are essential.
