Purpose: In this study an examination was done of the effect of self-efficacy promoting vestibular rehabilitation (S-VR) on dizziness, exercise selfefficacy, adherence to vestibular rehabilitation (VR), subjective and objective vestibular function, vestibular compensation and the recurrence of dizziness in patients with vestibular hypofunction. Methods: This was a randomized controlled study. Data were collected 3 times at baseline, 4 and 8 weeks after beginning the intervention. Outcome measures were level of dizziness, exercise self-efficacy, and level of adherence to VR. Subjective and objective vestibular function, vestibular compensation and the recurrence of dizziness were also obtained. Data were analyzed using Windows SPSS 21.0 program. Results: After 4 weeks of S-VR, there was no difference between the groups for dizziness, subjective and objective vestibular functions. However, exercise self-efficacy and adherence to VR were higher in the experimental group than in the control group. After 8 weeks of S-VR, dizziness (p =.018) exercise self-efficacy (p <.001), adherence to VR (p <.001), total-dizziness handicap inventory (DHI) (p =.012), vision analysis ratio (p =.046) in the experimental group differ significantly from that of the control group. The number of patients with recurring dizziness were higher in the control group than in the experimental group (p <.001). Conclusion: The results indicate that continuous 8 weeks of S-VR is effective in reducing dizziness, and improving exercise self-efficacy, subjective vestibular function and adherence to VR. Objective vestibular function and vestibular compensation were also improved in the experimental group at the end of 8 weeks of S-VR.

The effect of nurse‐led digital health interventions on blood pressure control for people with hypertension: A systematic review and meta‐analysis

“…A total of three studies reported self‐management results that were measured using the Hill‐Bone Compliance to High Blood Pressure Therapy Scale (Abu‐El‐Noor et al, 2021), Adherence to Treatment of Systemic Hypertension (Mattei da Silva et al, 2020), and the tool developed by Lee (1995). Nurse‐led DHIs were shown to improve self‐management in people with hypertension (SMD = 0.98, 95% CI: 0.58 to 1.37, Z = 4.39, p < 0.05, I 2 = 63.2%, Figure 5a).…”

Physiotherapists’ Perspectives Towards Using Telehealth for Acute Concussion Care

“…The interest in applying visual stimuli to produce neural adaptation and improvement in functional abilities in this population has drawn interest from technology-assisted methods (Zanier et al, 2018). The use VPT, such as VR and AR, has been recently suggested as advantageous in other neurological groups (Lee & Choi-Kwon, 2016), though the effectiveness and efficacy of such an intervention is limited at present. Within the concussion population, more recent interest has focused on VR and AR's use in the assessment process (Wright et al, 2017), with a gap in the literature around its potential use in treatment.…”

Awareness about the necessity of vestibular rehabilitation education in Korean physical therapists

“…After that, handouts are provided for patients to exercise at home (Kim, 2013;Lee et al, 2011). Recently, Lee and Choi-Kwon (2016) reported that the implementation rate of self-home exercise for patients with peripheral vestibular disease was very low. Many researchers reported that individualized VR tailored by a physical therapist was more effective than general VR (Gottshall, 2011;Norré and Beckers, 1988;Sessoms et al, 2015) because physical therapists play an important role in directly restoring patient function and return to daily life by identifying the patient's specific impairments and functional limitations.…”
