Effects of workplace upper extremity resistance exercises on function and symptoms of workers at a tertiary hospital: a randomized controlled trial protocol.

Background: Work-related musculoskeletal disorders (WRMDs) are often caused by inadequate use of the musculoskeletal system during work. Evidence suggests that multimodal intervention through exercises, massage, education, and ergonomic guidelines reduces pain and symptoms in the neck and upper extremities and help to prevent musculoskeletal disorders. The purpose of this study will be to assess the additive effectiveness of a specific and individualized workplace strengthening exercise program to an ergonomic guidance in reducing fatigue, pain and discomfort in the upper extremities and neck perceived by workers.

Association between muscle strength, upper extremity fatigue resistance, work ability and upper extremity dysfunction in a sample of workers at a tertiary hospital.

Background: Upper extremity musculoskeletal disorders negatively affect ability to perform activities of daily living, self-care and work. Therefore, outcome measurements that address muscle strength, fatigue resistance, functionality and work physical capacity must be defined to assess and plan specific actions to minimize them.

Objective: To investigate the association of upper extremity muscle strength with upper extremity fatigue resistance, work ability and upper extremity dysfunction in a sample of workers from a tertiary hospital.

Reliability, validity and responsiveness of Brazilian version of QuickDASH.

Objective: To analyse the construct validity, test-retest reliability and responsiveness of the Brazilian version of Quick-DASH (QD-Br) in patients with upper limb disorders.

Method: Participants completed the full Brazilian DASH, the QD-Br and the SF-12 Brazil questionnaires at the beginning of treatment, after 48-72h and the after 2-12 months. Construct validity was analysed by Pearson's correlation coefficient (r).

Construct validity of the Patient-Rated Wrist and Hand Evaluation questionnaire (PRWHE) for nerve repair in the hand.

Background: Many tools have been described for outcome assessment after nerve repair. The Patient-Rated Wrist and Hand Evaluation (PRWHE) have been shown to be valid for several hand conditions.

Objectives: To explore the construct validity of the PRWHE in comparison to cold intolerance, pain and dysfunction questionnaires; the Rosén score and its subcomponents; and threshold sensibility, dynamometry and dexterity tests for nerve repair of the hand.

Functional, motor, and sensory assessment instruments upon nerve repair in adult hands: systematic review of psychometric properties.

Background: Outcome after nerve repair of the hand needs standardized psychometrically robust measures. We aimed to systematically review the psychometric properties of available functional, motor, and sensory assessment instruments after nerve repair.

Methods: This systematic review of health measurement instruments searched databases from 1966 to 2017.
