Evaluation of the Balance, Muscular Electric Activity, Proprioception Before and After in the Vibratory Platform
Condition: Therapeutics
Study type: Interventional

Summary: 
      Introduction: Proprioception refers to the information's dynamic, sent to central nervous
      system by the free nerve endings and mechanoreceptors, about the biomechanics relationship
      for the joint tissue. The proprioceptive exercises show a big prophylactic action by
      musculoskeletal injuries. Among the top modalities of these exercises, it can be cited the
      Whole Body Vibration (WBV). Objectives: The objective of this study was to evaluate and
      compare the joint position sense, muscle electric activity and the postural sway in healthy
      individuals, before and after performing proprioceptive exercises on the vibrational platform
      or on a stable surface. Materials and Methods: 20 healthy young (24,85 + 4,27 years) were
      recruited, randomly divided into two groups, Control Group (GC) and Experimental Group (GE).
      Were realized evaluates of the proprioception by means of the joint position sense, the
      muscle electric activity of peroneus longus, gastrocnemius medialis, vastus medialis and
      gluteus medium, and the postural sway by means of the postural sway before and after one
      assistance consisting of 4 sets of 60s with unipodal standing position on soil (GC) or on
      vibrational platform (GE).
    

Detailed description: 
      The individuals who composed the two groups performed the same exercise protocol, however, on
      different surfaces:

        -  Control group: stable surface.

        -  Experimental group - vibratory platform, make / model Nissan Fisio; orbital amplitude: 6
           mm; frequency: 30 Hz The exercises consisted of unipodal support on the non-dominant
           lower limb with the contralateral limb in a knee flexion near 90º. This exercise is a
           proprioceptive test that requires more than all joints and musculature of the lower
           limb, and is widely used in studies, for providing obvious clinical signs in the
           presence of dysfunctions.

      Activities were performed with the individual standing without using any type of footwear,
      remaining without support of the hands and with the upper limbs abducted to 90º with the
      fixed eye on the horizon line. Both groups performed 4 sets of 60s of sustained posture. In
      the intervals between the series there was the rest of 60s, remaining in orthostasis with
      support of the upper limbs.
