Item Vestibulo-ocular reflex gain for adults 20-30 years(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2023) Fasra, M.F.F.; Karunarathne, S.; Dantanarayana, N.INTRODUCTION: Vestibular Ocular Reflex (VOR) is a critical visual component that ensures gaze stability during head movement, with counter eye movement due to activation of vestibular system. The video Head Impulse Test (vHIT) is an objective assessment of the VORfunction of the semicircular canals by measuring VOR gain. OBJECTIVE: To establish norms for the vestibulo-ocular reflex gain for healthy adults aged 20-30 years through the video head impulse test. Furthermore, the study analyzed the association of VOR gain with age and the asymmetry of VOR gain between ears. METHODS: 178 persons with normal peripheral hearing sensitivity and no known vestibular disorder were selected through convenient sampling. A series of testing in three stages was conducted along with an interviewer administered questionnaire. Instantaneous gain at 40 ms, 60 ms, 80 ms for both rightward and leftward rotations were used separately to analyze the data. RESULTS: The mean horizontal VOR velocity gain was 1.05(+0.195) for the right and 0.98(+0.191) for the left, at 40ms, 1.10(+0.146) for the right and 1.06(+0.13) for the left, at 60ms, 1.09 (+0.163) for the right and 1.08(+0.156) for the left, at 80 ms.No significant relationship was identified with age and VOR gain in either ear except for 80ms in the left ear (F=(1,153)= 4.97, p =0.03) which gradually decreased with the participants’ age and this linear relationship was significant. CONCLUSION: The horizontal VOR velocity gain remained around one in all tested subjects for both right and left, with a significant association only at 80ms with age among 20 -30 years. Established normative values permit the comparison of test results and identification of deviations in that age group.Item Experiences and Expectations of Adults who Stutter Attending Speech and Language Therapy for Stuttering in Sri Lanka(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2023) Ampemohotti, A.M.N.L.; Nonis, D.INTRODUCTION: The role of adults who stutter (AWS) in stuttering treatment has evolved from a passive recipient to an ‘expert’ partner in the collaborative therapeutic process. There is limited understanding of the experiences and expectations of AWS in relation to speech and language therapy for stuttering in the Sri Lanka. OBJECTIVES: The study explored experiences and expectations of adults who stutter attending speech and language therapy for stuttering in Sri Lanka. METHODOLOGY: This study used a generic qualitative approach. Online semi-structured interviews were conducted in Sinhala language via Zoom with 12 AWS recruited from a state university clinic in Sri Lanka. The interviews were audio recorded, transcribed verbatim, translated into English language, and analyzed using thematic analysis. RESULTS: Four themes were developed from the data: 1) limited awareness of stuttering and its management, 2) impact of stuttering on AWS, 3) experiences of coping with stuttering before attending therapy, and 4) perceptions towards successful management of stuttering. Many participants’ expectation for therapy was to improve fluency. The results indicated contrasting experiences of AWS before and after successful management of stuttering and multiple personal, therapeutic, and social factors that contribute to achieving successful therapeutic outcomes. CONCLUSION: The study emphasizes the importance of individualized therapy to improve the likelihood of successful therapeutic outcomes. Being absolutely fluent is not a necessary criterion for the successful management of stuttering. The findings highlight the need to promote awareness of stuttering and its management and the profession of speech and language therapy among the Sri Lankan public.
