RESUMO
The swallowing quality of life (SWAL-QOL) questionnaire is a commonly used tool to assess the impact of dysphagia on quality of life. SWAL-QOL has been translated and validated in many languages. There is no valid dysphagia-specific quality of life tool in Indian languages. Hence, the current study aimed at cultural adaptation, translation, and validation of SWAL-QOL in Kannada (KSWAL-QOL), a south Indian Dravidian language. The original SWAL-QOL was translated into Kannada using the standard translation procedure. A group of 55 participants with oro-pharyngeal dysphagia (clinical group) and 55 participants with normal swallowing abilities (control group) were recruited for the current study to assess the validity and reliability of KSWAL-QOL. Dysphagia Handicap Index- Kannada version (DHI-K) and Life Satisfaction Questionnaire (LISAT) were used to check for the convergent validity of the KSWAL-QOL. The KSWAL-QOL demonstrated excellent discriminant validity and distinguished clinical from the control group across all domains (p = 0.00). Internal consistency for all the nine domains of KSWAL-QOL measured using Cronbach's α ranged from 0.89 to 0.92, demonstrating excellent reliability. Test-retest measures were exceptional, with Intraclass Correlation Coefficient (ICC) ranging between 0.92 and 0.98 and Spearman's rho values between 0.91 and 0.97. A very strong negative correlation was obtained between KSWAL-QOL and DHI-K, and a strong positive correlation was seen between KSWAL-QOL and LISAT. The KSWAL-QOL is a reliable and valid tool with excellent psychometric properties to evaluate the quality of life associated with swallowing in individuals with oropharyngeal dysphagia.

RESUMO
Introduction: Effortful swallow with progressive resistance has a potential clinical implication in improving the oro-muscular strength, swallow safety, and efficiency in elderly individuals. But to date, no studies have explored its benefits in training individuals with post-stroke dysphagia. Aim: The present study investigated the long- term effect of effortful swallow with progressive resistance on swallow safety, efficiency and quality of life in persons with dysphagia following stroke. Method: The study consisted of 5 males (mean age: 41.80yrs ± 9.6yrs) diagnosed with dysphagia post-stroke. The participants underwent 20 sessions (5 days/week) of intensive effortful swallow with progressive training spread across four weeks. In the first two weeks, the participants performed 10 × 3 sets of effortful swallows with a 50% of resistance load, which was further increased to 15 × 3 sets with a 70% resistance load. Results: DIGEST-FEES safety and overall swallow quality of life significantly improved post-therapy, whereas DIGEST-FEES efficiency and overall swallow grades showed no significant changes. Inter-rater reliability of DIGEST-FEES revealed substantial agreement between judges. Conclusion: The results are promising as the technique improved swallow safety, and swallow quality of life in persons with dysphagia following stroke.
