Development and cross-cultural adaptation of the vestibular disorders activities of daily living scale in the kannada language and testing its psychometric properties.

Background: Vestibular Disorders Activities of Daily Living Scale (VADL) is a self-reported survey for assessing functions of individuals affected by vestibular disorders, and this survey has been translated and cross-culturally adapted into many languages. Objective: : Kannada is one of the most-spoken languages in India, with approximately 64 million speakers. We aimed to develop the Kannada version of VADL and to assess its psychometric properties. Materials and Methods: The translation and adaptation of the English version of VADL into Kannada were accomplished with the input of medical professional language experts. Pretesting of the Kannada VADL (VADL-K) was conducted on 30 patients with vestibular disorders. Six professional experts with medical background provided their opinion during the content validation process of VADL-K, and 50 subjects aged between 30 and 70 years with variant vestibular disorders were administered VADL-K and the Dizziness Handicap Inventory to determine the internal consistency, test-retest reliability, and concurrent validity of this assessment. Results: This study effectively translated, adapted, and pretested VADL-K. The scale's content validity was 0.95, its internal consistency (Cronbach's alpha = α) was 0.94, its test-retest reliability with Intra Class- Correlation Coefficient was 0.97, and its concurrent validity in comparison with DHI was significant, with a moderate correlation r-value of 0.58. Conclusion: The English version of VADL was successfully translated and adapted into the Kannada language. VADL-K is a valid and reliable measure for patients with vestibular disorders in the state of Karnataka to report their functional performance.

Normative reference values for functional, lateral, and oblique direction reach tests in Saudi children aged six to 15 years old and psychometric properties of the oblique direction reach test.

AIMS: To establish normative values for functional, lateral, and Oblique Direction Reach Tests (ODRT) and to assess the validity and reliability of the ODRT in Saudi children of age 6-15 years. METHODS: Three hundred Saudi children of age 6-15 years children were recruited by using snowball sampling. Children were measured for distance reached in forward, lateral, and oblique direction on a graph paper, which was mounted on a wall/cardboard. RESULTS: The Mean ± SD for forward, lateral and oblique direction reach was 25.63 ± 6.95, 18.91 ± 5.66, 22.08 ± 5.98 cm respectively. The Intraclass Correlation Coefficient values of intra and inter-rater reliability of ODRT shown to be 0.94 and 0.91, respectively. Concurrent validity of ODRT with forward and lateral reach test is 0.87 and 0.84, respectively. CONCLUSION: : We established the normal values for functional, lateral, and ODRT in 6-15 years of Saudi children. We found that ODRT is a valid and reliable for measuring limits of stability in oblique direction.

Effects of patient-specific three-dimensional lumbar traction on pain and functional disability in patients with lumbar intervertebral disc prolapse.

BACKGROUND: Prolapsed lumbar intervertebral disc is one of the most prevalent causes of low back pain and traction is one of the most common physical therapy treatments offered to affected patients. Advancements in traction equipment are needed to ensure their effectiveness in clinical situations. AIMS: The objective of the study was to find out the effect of patient-specific three-dimensional lumbar traction on pain and functional disability in individuals with lumbar intervertebral disc prolapse. SUBJECTS AND METHODS: Original article and Experimental design. Twenty-five participants (age range: 34-67 years) diagnosed with lumbar intervertebral disc prolapse were included in this study. Patient-specific three-dimensional lumbar traction was given as three sessions per week for the duration of one month. All participants completed a 10-cm visual analog pain scale and pain pressure threshold to assess pain and the Oswestry disability index to assess the functional disability. RESULTS: On pre to post interventions, a significant change in mean values were found for visual analog scale pain score, pain pressure threshold, and Oswestry disability index (P < 0.001). The pain intensity was reduced from 8.5 to 3.2, pain pressure threshold increased from 0.7 to 1.6 kg/cm2, and functional disability was reduced from 53.5% to 31.3%. CONCLUSION: Twelve sessions of patient-specific three-dimensional lumbar traction promoted a reduction in pain and improvement in functional disability among subjects with lumbar intervertebral disc prolapse.
