Item Concordance and Discordance Between Measured Balance and Perceived Balance and the Effect on Gait Speed and Falls Following Stroke(2016) Liphart, JodiObjective: To ascertain the existence of discordance between perceived and measured balance in persons with stroke and to examine the impact on walking speed and falls. Design: A secondary analysis of a phase three, multicentered randomized controlled trial examining walking recovery following stroke. Subjects: A total of 352 participants from the Locomotor Experience Applied Post-Stroke (LEAPS) trial. Methods: Participants were categorized into four groups: two concordant and two discordant groups in relation to measured and perceived balance. Number and percentage of individuals with concordance and discordance were evaluated at two and 12 months. Walking speed and fall incidence between groups were examined. Main measures: Perceived balance was measured by the Activities-Specific Balance Confidence scale, measured balance was determined by the Berg Balance Scale and gait speed was measured by the 10-meter walk test. Results: Discordance was present for 35.8% of participants at two months post stroke with no statistically significant change in proportion at 12 months. Discordant participants with high perceived balance and low measured balance walked 0.09 m/s faster at two months than participants with concordant low perceived and measured balance (p < 0.05). Discordant participants with low perceived balance and high measured balance walked 0.15 m/s slower than those that were concordant with high perceived and measured balance (p ⩽ 0.0001) at 12 months. Concordant participants with high perceived and measured balance walked fastest and had fewer falls. Conclusions: Discordance existed between perceived and measured balance in one-third of individuals at two and 12 months post-stroke. Perceived balance impacted gait speed but not fall incidence.Item The Use of Sensory Reweighting for a Woman with Persistent Mal de Debarquement: A Case Report(2015) Liphart, JodiBackground and Purpose: Persistent mal de debarquement is an uncommon disorder occurring after a sea voyage, or a plane or train trip. Symptoms include unsteadiness, rocking sensation, visual motion intolerance, cognitive slowing, and excessive fatigue. It is thought to be a result of faulty multisensory adaptation. The purpose of this case report was to describe the use of sensory reweighting, a therapeutic approach aimed at reweighting the balance between the 3 sensory systems, to decrease symptoms and increase functional abilities of a woman with persistent mal de debarquement. Case Description: A 69-year-old woman with a 4-year history of persistent mal de debarquement after a plane trip reported a constant feeling of rocking, unsteadiness, and a loss of balance in low lighting or visually rich environments. She experienced a previous fall and had limited her social activities because of her symptoms. Interventions: Sensory reweighting therapy was administered twice a week for 10 weeks. Activities included balance training using vestibular, somatosensory, and visual challenges to vary the sensory input available. Outcomes: A 5-point increase was observed on the Berg Balance Scale, she doubled her balance time in tandem stance position, and improved from moderate to low impairment on the Dizziness Handicap Inventory. She had a significant change on the Global Rating of Change Scale. Subjectively, she felt she had improved 50% and was less disabled. Discussion: A rehabilitation approach aimed at sensory reweighting improved this patient's function and community reintegration. Her symptoms were reduced and stability and balance improved.
