Validação do questionário de avaliação funcional das mãos em hanseníase

Abstract

OBJECTIVE:To validate the psychometric properties of the questionnaire on hand function assessment in leprosy. METHODS:Study conducted with a convenience sample of 101 consecutive patients in Brasília (Central-Western Brazil), from June 2008 to July 2009. The individuals were adults affected by leprosy, with impairment of the ulnar, median and radial nerves. Interobservers and intraobserver reproducibility was analyzed through successive interviews, and construct validity was analyzed through association between age, clinical form of leprosy, duration of nerve injury, grip and pinch strength measured with a dynamometer, sensibility test performed with Semmes-Weinstein monofi laments and manual ability assessment using the Jebsen test of hand function. Pondered kappa coeffi cient was calculated and a Bland-Altman plot was constructed to assess the reproducibility of the instrument. For internal consistency, Cronbach's alpha coeffi cient was utilized. Pearson's correlation coeffi cient was calculated and a multiple regression model was used. RESULTS:The pondered kappa values for interobservers and intraobserver assessments ranged from 0.86 to 0.97 and from 0.85 to 0.97, respectively. The value of Cronbach's alpha coeffi cient was 0.967. Pearson's correlation coeffi cient showed an association (p < 0.001) among duration of nerve injury, grip and pinch strength, cutaneous sensibility and mean score in the Jebsen Test. The mean score of the questionnaire on hand functional assessment in leprosy was associated with operational classifi cation of leprosy, duration of nerve injury, grip strength, cutaneous sensibility and manual ability (p < 0.0001 for the model as a whole). CONCLUSIONS:The questionnaire on hand functional assessment in leprosy presents almost perfect interobservers and intraobserver reproducibility, high internal consistency and correlation with operational classifi cation of leprosy, duration of nerve injury, grip strength, cutaneous sensibility in the hands and manual ability.

Knowledge assessment instrument on basic support of hip fractures in the elderly

“…The results provided evidence that the elaborated instrument has sufficient internal consistency to level analysis 13 of knowledge in basic life support of undergraduate students on the health area, indicating that it may be used as an evaluation tool. They also showed that knowledge in damage and injuries caused by hip fractures in the elderly can be isolatedly measured, which was not observed regarding risk factors.…”

“…The results regarding the proportion of explanation of each item in relation to the parts (between items), as well as each part regarding the entire instrument (inter-parts) are presented through values of Cronbach's alpha 13 in Table 2 .…”

Physical Therapy Improved Hand Function in a Patient with Traumatic Peripheral Lesion: A Case Study

“…We used the questionnaire developed by Ferreira et al (2012) to Evaluate the Hands Function with Nerve Lesions, especially for the involvement of the median, ulnar and radial nerves, before and after the rehabilitation program. Patient presented an improvement of the majority of the functions after the rehabilitation program (Table 2).…”

“…We used the questionnaire developed by Ferreira et al (2012) to Evaluate the Hands Function with Nerve Lesions, but numerous instruments have been proposed for the hand function evaluation in specific diseases after traumatic injuries. Among them, the most commonly used are Scale Cochin Questionnaire (Duruoz et al, 1996), ADL Questionnarie (Rosen, 2006), Green Pastures Activity Scale (Brakel et al, 1999) and Karigiri Activities of Daily Living Rating Scale (Rajkumar et al, 2002).…”

“…1). After the application of the Questionnaire to Evaluate the Hands Function with Peripheral Nerve Lesions (Ferreira et al, 2012), it was possible to see functional impairments (Table 2). Electromyography identified an increase of distal latency of the ulnar nerve in the left upper limb affected, with great reduction of the potential amplitude of motor actions by stimulating both the wrist and the elbow.…”
