Urdu Version Of Cornell Musculoskeletal Discomfort Questionnaire: Reliability And Validity Study

Study Overview
=================
Brief Summary
-----------------
The study aims to translate and adapt Cornell Musculoskeletal Discomfort Questionnaire cross-culturally into the Urdu language for the Pakistani population for investigating the reliability and validity of Cornell Musculoskeletal Discomfort Questionnaire in the Pakistani population and to study the correlation between Nordic Musculoskeletal Questionnaire and the Visual Analogue Scale.

Detailed Description
-----------------
The English version of the Cornell Musculoskeletal Discomfort Questionnaire will be translated into Urdu and culturally adapted, as per a previous recommendation. The Cornell Musculoskeletal Discomfort Questionnaire will be given to one hundred and fifty workers of Masood Textile Mills, who would be chosen based on convenience sampling and inclusion and exclusion criteria. The inter-observer and intra-observer reliability of the Cornell Musculoskeletal Discomfort Questionnaire, Nordic Musculoskeletal Questionnaire, and Visual Analog Scale will be evaluated in this study. On the same day, the questionnaire will be filled out created two times. An Inter - observer assessment will be done with 2 hour break between distributions of questionnaires. The initial observer then will gather a third assessment over one-week period (intra-observer assessment). For data entry and analysis, Statistical Package of Social Sciences Version 24 will be utilized. Internal consistency will be checked using the Cronbach alpha value, and test retest reliability will be assessed using the Intraclass coefficient.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cornell Musculoskeletal Discomfort Questionnaire | This questionnaire is used to access discomfort caused by Musculoskeletal disorders. It has 3 scales, frequency, severity and interference scale. It has 3 versions on the basis of the nature of work place and activity level i.e. Sedentary workers, standing workers and hand discomfort. Sedentary workers don't include the foot domain while the standing worker has this domain. The hand discomfort version is used to access only hand problems. Its interpretation can be done by multiplying all the scale score. | 1st day | 
| Nordic Musculoskeletal Questionnaire | The Nordic Questionnaire is an internationally recognized tool for standardization research on Musculoskeletal symptom assessment. Its goal is to use an ergonomically approach to analyze Musculoskeletal problems. The very first component of this instrument includes questions on body parts that correlate to nine anatomical regions. The questions were structured in the following sequence: yearly and weekly prevalence; functional disability; and seeking medical treatment in the last year. This questionnaire can be used in an examination or by the individual who is now being assessed. | 1st day | 
| Visual Analogue Scale | The Visual Analogue Scale was created to represent the concept of a fundamental continuity. A Visual Analogue Scale is typically a straight stripe measuring 100 mm long, with word descriptions for each end. The patient draws a line through the spot on the line which they believe best describes their present state. The Visual Analogue Scale score is calculated by calculating in millimeters as from the line's left side to the point marked by that of the patient. It usually ranges from 0 indicating no pain to the 10 indicating worst pain. | 1st day |
