Test of grip strength using the Jamar dynamometer

The measurement of grip strength is an important element in hand rehabilitation. Tests of grip strength are often used to assess patients with upper extremity disorders, before and after therapeutic procedures. These tests are simple to administer and if properly conducted, they provide objective information that may contribute to the analysis of hand function. The test protocol must be carefully developed and adequately followed. A well-recommended instrument in the literature is the Jamar dynamometer, with high rates of reliability and validity. This instrument has been accepted as a gold standard for the measurement of grip strength and has been frequently used in clinical practice by occupational and physical therapists. The present study reviews some aspects involved in the measurement of grip strength using the Jamar dynamometer, including the instrument reliability and precision, a suggested protocol for its use, important variables that may influence the results, the use of normative data and the factors that influence grip strength such as the individual’s sex, age, weight and height. Recommendations are made regarding these variables in order to help the clinicians’ conduct appropriate assessments of grip strength.

Development of a first-contact protocol to guide assessment of adult patients in rehabilitation services networks

Objective: This paper describes the development of the Protocol for Identification of Problems for Rehabilitation (PLPR), a tool to standardize collection of functional information based on the International Classification of Functioning, Disability and Health (ICF). Development of the protocol: The PLPR was developed for use during the initial contact with adult patients within a public network of rehabilitation services. Steps to develop the protocol included: survey of the ICF codes most used by clinical professionals; compilation of data from functional instruments; development and pilot testing of a preliminary version in the service settings; discussion with professionals and development of the final version. The final version includes: user identification; social and health information; brief functional description (BFD); summary of the BFD; and PLPR results. Further testing of the final version will be conducted. Conclusions: The protocol standardizes the first contact between the user and the rehabilitation service. Systematic use of the protocol could also help to create a functional database that would allow comparisons between rehabilitation services and countries over time.

Whole-body vibration and musculoskeletal diseases in professional truck drivers

Background: Most occupational diseases do not fit the paradigm of medical interpretation of the health-disease process based on linear causality, in which it would be possible to find a single cause for each type of disease. Objectives: to conduct a systematic review in order to investigate the association between whole-body vibration (WBV) and musculoskeletal disorders (MSD) in professional truck drivers (PTD). Methods: The scientific databases of PubMed, Cochrane, Lilacs and Scielo were used to collect articles published from 2000 until the present time. Two independent reviewers adopted inclusion and quality criteria to evaluate the selected articles. Results: From adopted inclusion and quality criteria, nine articles were chosen to identify the association between MSD and WBV in PTD. The results showed that MSD seems to be closely associated to exposure to WBV in these workers, mainly due to high prevalence and symptoms of low back pain. Two cohort studies showed exposure to WBV as risk for MSD. Only one, with case-control design, did not show WBV as a significant factor. Conclusions: In this study the importance of exposure analysis of WBV in the occurrence of MSD in PTD was elucidated. This study showed the importance of WBV exposure analysis on the occurrence of MSD in PTD. There is adequate information to provide rationale for the reduction of WBV exposure to the lowest possible level, to ensure the health of these workers. Studies with a greater power of investigation, of a prospective, design, should be encouraged, supplanting those only of association.

Exploring the organization of daily life among women with disabilities in Belo Horizonte, Brazil: perspectives of functionality and temporality

Time is a fundamental instrument of orientation for social life, and it is closely intertwined with both public and private spaces and the resources contained therein. The aim of this study is to describe and analyse the organization of daily life among women with disabilities in Belo Horizonte, Brazil, from the perspective of temporality. Results were obtained by a combination of quantitative and qualitative methods, using a sample of 50 women with physical/motor disabilities. They self-reported difficulties when walking and/or climbing stairs. The analysis of time use by individuals with disabilities revealed six main types of activities associated with daily life: personal care, paid work, studying, housework, free time, and travelling from one place to another. The results reveal that although the daily lives of these women are hampered by their functional limitations, their lives are also directly influenced by their physical and social contexts and their attitudes.

Cross-cultural adaptation to Brazilian Portuguese of the Activity Measure for Post-Acute Care (AM-PAC) short forms for outpatients in rehabilitation

Highlights • AM-PAC evaluate mobility, daily activity and applied cognition, according to ICF.• The translation process followed the procedures of specific guidelines.• The Brazilian version maintains the original meaning of the AM-PAC items.• Short forms of the AM-PAC/Brazil showed satisfactory reliability indices.
