Avaliação e tratamento fisioterapêutico em trabalhadores portadores da síndrome do impacto do ombro.
Abstract
This study evaluated the effectiveness of a standardized supervised therapeutic
program performed during working hours on physical function and pain in workers with
shoulder impingement stages I and II. Methods: Fourteen assembly line male workers
(31.93 ± 5.86 years) with unilateral shoulder impingement stages I and II. The Disabilities
of the Arm, Shoulder and Hand (DASH) questionnaire evaluated function of the upper
limbs. The McGill Pain Questionnaire quantified the pain by the number of words chosen
and the pain rating index (PRI). Physical performance was evaluated by torque, total work
and acceleration time that were measured bilaterally during isokinetic concentric abduction
and lateral and medial rotations in the scapular plane, at 60°/s and 180°/s. Subjects
completed an eight-week intervention program, consisting of cryotherapy, strengthening
and stretching exercises, performed twice a week during working hours, and they were
evaluated pre- and post-intervention. Results: DASH scores improved (P < 0.05) and the
number of words chosen and PRI decreased (P < 0.05) at post-intervention. Torque
improved (P < 0.05) in the abduction at 60°/s and in the medial rotation for both speeds
after the therapeutic intervention. Total work increased (P < 0.05) at post-intervention for
abduction and medial rotation at 60°/s and 180°/s. Acceleration time decreased (P < 0.05)
in the abduction at 180°/s compared to the pre-intervention period. No changes were
observed (P > 0.05) in any variable during lateral rotation. Conclusion: A rehabilitation
program performed during working hours seems to improve symptom and physical
performance in workers with shoulder impingement stages I and II.
