Background The frequency and impact of undiagnosed benign paroxysmal positional vertigo (BPPV) in people identified with high falls risk has not been investigated. Objective To determine the frequency and impact on key psychosocial measures of undiagnosed BPPV in adult community rehabilitation outpatients identified with a high falls risk. Design A frequency study with cross-sectional design. Setting A Community Rehabilitation Program in Melbourne, Australia. Subjects Adult community rehabilitation outpatients with a Falls Risk for Older People in the Community Screen score of four or higher. Methods BPPV was assessed in 34 consecutive high falls risk rehabilitation outpatients using the Dix–Hallpike test and supine roll test. Participants were assessed for anxiety, depression, fear of falls, social isolation and loneliness using the Hospital Anxiety and Depression Scale, Falls Efficacy Scale-International and De Jong Gierveld 6-Item Loneliness Scale. Results A total of 18 (53%; 95% confidence interval: 36, 70) participants tested positive for BPPV. There was no significant difference between those who tested positive for BPPV and those who did not for Falls Risk for Older People in the Community Screen scores (P  = 0.555), Hospital Anxiety and Depression Scale (Anxiety) scores (P  = 0.627), Hospital Anxiety and Depression Scale (Depression) scores (P  = 0.368) or Falls Efficacy Scale-International scores (P  = 0.481). Higher scores for the De Jong Gierveld 6-Item Loneliness Scale in participants with BPPV did not reach significance (P  = 0.056). Conclusions Undiagnosed BPPV is very common and associated with a trend towards increased loneliness in adult rehabilitation outpatients identified as having a high falls risk.

Purpose:To assess the orthotic and therapeutic effects of prolonged use of functional electrical stimulation (FES) on fatigue induced gait patterns in people with Multiple Sclerosis (MS).Method:Thirteen people with MS completed 3D gait analysis with FES off and on, before and after a fatiguing 6-minute walk, at baseline and after 8 weeks of use of FES.Results:Eleven participants completed all testing. An orthotic effect on gait was not evident on first use of FES. However, therapeutic effects on gait after 8 weeks use were generally positive, including increases in walking speed due to improved neuromuscular control and power generated at the hip and ankle of the more affected limb. The action of FES alone was not sufficient to overcome all fatigue related deficits in gait but there was evidence 8 weeks use of FES can ameliorate some fatigue effects on lower limb kinetics, including benefits to ankle mechanics involved in generating power around push-off during stance.Conclusions:Eight-weeks of FES can benefit the gait pattern of people with MS under non-fatigued and fatigued conditions.Implications for rehabilitationIn some people with MS prolonged use of FES may be necessary before observing positive orthotic effects.Improvements in the neuromuscular control of the more affected lower limb may develop with prolonged use of FES in people with MS.Only some therapeutic benefits of FES are maintained during fatigued walking in people with MS.FES may be considered as a gait retraining device as well as an orthotic intervention for people with MS.
