Background: Uncompensated vestibular hypofunction results in postural instability, visual blurring with head movement, and subjective complaints of dizziness and/or imbalance. We sought to answer the question, “Is vestibular exercise effective at enhancing recovery of function in people with peripheral (unilateral or bilateral) vestibular hypofunction?” Methods: A systematic review of the literature was performed in 5 databases published after 1985 and 5 additional sources for relevant publications were searched. Article types included meta-analyses, systematic reviews, randomized controlled trials, cohort studies, case control series, and case series for human subjects, published in English. One hundred thirty-five articles were identified as relevant to this clinical practice guideline. Results/Discussion: Based on strong evidence and a preponderance of benefit over harm, clinicians should offer vestibular rehabilitation to persons with unilateral and bilateral vestibular hypofunction with impairments and functional limitations related to the vestibular deficit. Based on strong evidence and a preponderance of harm over benefit, clinicians should not include voluntary saccadic or smooth-pursuit eye movements in isolation (ie, without head movement) as specific exercises for gaze stability. Based on moderate evidence, clinicians may offer specific exercise techniques to target identified impairments or functional limitations. Based on moderate evidence and in consideration of patient preference, clinicians may provide supervised vestibular rehabilitation. Based on expert opinion extrapolated from the evidence, clinicians may prescribe a minimum of 3 times per day for the performance of gaze stability exercises as 1 component of a home exercise program. Based on expert opinion extrapolated from the evidence (range of supervised visits: 2-38 weeks, mean = 10 weeks), clinicians may consider providing adequate supervised vestibular rehabilitation sessions for the patient to understand the goals of the program and how to manage and progress themselves independently. As a general guide, persons without significant comorbidities that affect mobility and with acute or subacute unilateral vestibular hypofunction may need once a week supervised sessions for 2 to 3 weeks; persons with chronic unilateral vestibular hypofunction may need once a week sessions for 4 to 6 weeks; and persons with bilateral vestibular hypofunction may need once a week sessions for 8 to 12 weeks. In addition to supervised sessions, patients are provided a daily home exercise program. Disclaimer: These recommendations are intended as a guide for physical therapists and clinicians to optimize rehabilitation outcomes for persons with peripheral vestibular hypofunction undergoing vestibular rehabilitation.

Background: Vestibular dysfunction, characterized by nausea, dizziness, imbalance, and/or gait disturbance, represents an important sport-related concussion (SRC) subtype associated with prolonged recovery. Vestibular physical therapy promotes recovery; however, the benefit of earlier therapy is unclear. Hypothesis: Earlier vestibular therapy for young athletes with SRC is associated with earlier return to play (RTP), return to learn (RTL), and symptom resolution. Study Design: Retrospective cohort study. Level of Evidence: Level 3. Methods: Patients aged 5 to 23 years with SRC who initiated vestibular rehabilitation therapy (VRT) from January 2019 to December 2019 were included and patient records were reviewed. Therapy initiation was defined as either early, ≤30 days postinjury, or late (>30 days). Univariate comparisons between groups, Kaplan-Meier plots, and multivariate Cox proportional hazard modeling were performed. Results: Overall, 23 patients (10 early, 13 late) aged 16.14 ± 2.98 years and 43.5% were male patients. There was no difference between group demographics or medical history. Median initial total and vestibular symptom scores were comparable between groups. The late therapy group required additional time to RTP (110 days [61.3, 150.8] vs 31 days [22.5, 74.5], P = 0.03) and to achieve symptom resolution (121.5 days [71, 222.8] vs 54 days [27, 91], P = 0.02), but not to RTL (12 days [3.5, 26.5] vs 17.5 days [8, 20.75], P = 0.09). Adjusting for age and initial total symptom score, earlier therapy was protective against delayed symptom resolution (P = 0.01). Conclusion: This pilot study suggests that initiating VRT within the first 30 days after SRC is associated with earlier RTP and symptom resolution. Further prospective trials to evaluate if even earlier VRT should be pursued to further improve recovery time. Clinical Relevance: Clinicians should screen for vestibular dysfunction and consider modifying follow-up schedules after SRC to initiate VRT within a month of injury for improved outcomes.

The thesis deals with the issue of vestibular compensation in patiens after vestibular schwannoma surgery. The aim of this thesis was to objectively evaluate the dynamics of vestibular compensation in the early postoperative period and to determine whether the application of gentamicin impacts the dynamics of equilibrium functions. 32 patients participated in the study (20 women and 12 men) ranging from 28 to 73 years of age. Patients underwent a rehabilitation program with visual feedback using the interactive rehabilitation system, Homebalance. This rehabilitation program was carried out daily from the 5th postoperative day until hospital discharge. Patients were examined preoperatively, postoperatively and after rehabilitation. To assess the vestibular compensation, static posturography, the Synapsys Posturography System, and the Activities-Specific Balance Confidence Scale were used. The statistical analysis showed a significant increase in mean values of measured COP parameters (the length of the COP trajectory and COP confidence elipse area) postoperatively. After completing the rehabilitation program no significant reduction of measured COP parameters was found. The total score from the Activities- Specific Balance Confidence Scale showed a statistically significant decrease in postoperative...

Vestibular schwannoma surgery causes in majority of patients the unilateral peripheral or combined vestibular lesion due to surgical interruption of both branches of vestibular nerve. It manifests postoperatively with postural instability, vertigo, oscilopsia and even with vegetative symptoms. Central compensation, in which cerebellum plays dominant role, influences duration of the symptoms. Factors affecting compensation may be divided into several groups (general health status of a patient, the tumor itself, actual state of function of vestibular system, external factors induced by a therapeutist). Therapeutic aim is to induce compensatory mechanisms as soon as possible and to reduce overall duration of the compensation. The aim of this study is to consider predictive factors influencing central vestibular compensation and to influence the vestibular compensation itself. Early operated vestibular rehabilitation is a basic procedure. It leads to faster recovery in majority of patients. Even with maximal effort the full compensation is not always achieved. It results in permanent deficit of vestibular function manifested with postural instability. However in some patients it is difficult to achieve full compensation despite maximum effort of a physiotherapeutist and that results in permanent...

The aim of this thesis was to evaluate the effect of rehabilitation with visual biofeedback at acute stage after vestibular schwannoma surgery and to evaluate if preoperative intratympanic aplication of gentamicin has influence on vestibular compensation of standing stability. The study was attended by 20 patients (12 women and 8 men) in the age from 28 to 63 years. Eight patients had vestibular schwannoma diagnosed in their left side, twelve in the right side. Rehabilitation program using interactive rehabilitation system Homebalance took place from the 5th postoperative day until hospital discharge, daily 15 to 20 min. To evaluate of therapeutic intervention objectively the device Synapsys Posturography System was used. Stabilometric examination was done before operation of vestibular schwannoma, after operation and after termination of rehabilitation with visual biofeedback. Statistic analysis showed significant increase of mean values of measured parameters CoP (sway velocity CoP, length of trajectory of CoP, area of the confidence ellipse CoP) postoperatively compared to preoperative values. After termination of therapeutic intervention there was any significant decrease of values of parameters CoP compared to postoperative status. Between group of patients with preoperative aplication of...
