Whether these symptoms recover after treatment with repositioning maneuvers (RM) remains unclear. Methods: Twenty-five older adults with BPPV (oaBPPV) (73.2 ± 4.9 years) were compared to twenty-two age-matched controls (73.5 ± 4.5 years). OaBPPV were treated with RM until nystagmus resolved and evaluated pre-treatment and 1, 3 and 6 months post-treatment. Modified Fried criteria were used to assess frailty. Well-being was evaluated with the Dizziness Handicap Inventory (DHI) and Falls Efficacy Scale (FES-I). Postural control was assessed with the timed chair stand-test (TCST) and Timed-upand- go (TUG). PA was measured using the MOX accelerometer and the International Physical Activity Questionnaire (IPAQ). Results: OaBPPV experienced significantly more frailty symptoms (p\0.001), a higher DHI (p\0.001) and FES-I (p\0.001) and a reduced PA compared to controls. After RM, FES-I (p = 0.11), turn duration of TUG (p = 0.3) and IPAQ (p = 0.4) were equal to controls. Despite improvements, persistent deficits remained in DHI (p\0.001) and spatiotemporal parameters of gait (p = 0.002). Frailty (p = 0.8), TCST (p = 0.3) and objectively measured PA (p = 0.2) did not improve. Key conclusions: oaBPPV experience additional health problems besides BPPV, such as frailty, a co-existing vestibular hypofunction, or cognitive decline. RM improved some parameters, but there were persistent deficits in well-being, postural control, frailty and PA. After treatment with RM, clinicians should follow up on these problems to
