ABSTRACT
BACKGROUND: The Avoidance Endurance Questionnaire (AEQ) successfully measures the fear-avoidance and endurance-related responses to chronic pain. OBJECTIVE: The objective of this study was to translate, cross-culturally adapt AEQ into Urdu and assess the reliability and validity of the Urdu version. METHOD: For the translation and cross-cultural adaptation process, the Beaton Guidelines were followed. A total of 103 participants responded to the Urdu version of the AEQ SF-12, Pain Catastrophizing Scale (PCS) and Numeric Pain Rating Scale (NPRS) at baseline and after 48 hours. The test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Cronbach's alpha was used to measure internal consistency. To measure validity, Pearson's correlation between the subscales of AEQ-Urdu and other outcome measures (SF-12, PCS and NPRS scores) were used (p< 0.05). RESULTS: The mean age of the total 103 participants was 32.7 ± 10.90 among which 45 (43.6%) were male and 58 (56.3%) were female. The pre-final version of the translated AEQ was tested on 40 Urdu speaking participants and no major changes were made. The Cronbach's alpha for all subscales of the AEQ-Urdu ranged from 0.848-0.990. AEQ-U showed an excellent test-retest reliability with the ICC ranging from 0.775-0.996. The majority of the subscales of AEQ showed significant (p< 0.05) positive correlation with pain scales (PCS and NPRS) and negative correlation with the domains of SF-12. CONCLUSION: The AEQ-U has reliable and valid construct validity, good internal consistency, and test-retest reliability, indicating that it has adequate psychometric features and can be a useful tool for evaluating pain responses in patients with chronic musculoskeletal pain.
ABSTRACT
OBJECTIVE: To explore current evidence on the role of virtual reality and active video games in motor and executive functions compared to conventional physical therapies in cerebral palsy patients. METHODS: The systematic review was conducted at the University Institute of Physical Therapy, Lahore, Pakistan, and comprised search on MEDLINE via PubMed, Pedro and Cochrane Central related to randomised and clinical controlled trials published from 2005 to 2020. For critical appraisal of the studies, the Pedro tool was used, while methodological quality assessment was done using the Cochrane risk of bias tool. RESULTS: Of the 15 articles reviewed, 14(93.3%) reported significant effect of virtual reality and active video games on motor functions. Critical appraisal found the quality of the studies from fair to high. Low risk was found in 4(26.7%) articles in terms of selection, 3(20%) allocation, 6(40%) detection, and 8(53.3%) had attrition bias. Unclear risk was reported in the performance and reporting bias domain in all the 15(100%) articles. CONCLUSIONS: Virtual reality games cannot be used as a substitute for therapy, but along with the conventional physical therapy, they are very effective and produce significant changes in motor functions in cerebral palsy patients. As for executive functions, more research needs to be done to determine the impact of these games at a higher level of brain.
