Intervention(s)

15 sessions of knesiotherapy treatment, with attention directed to movement parameters

The treatment will last 5 weeks, with 3 sessions a week of 50 minutes each. 5 groups of two subjects will be formed for the treatment. The protocol of each session will be video taped, controling the time of each activity for each of the 5 groups. A film of one person with toracic medular legion performing a demonstration of necessary task, adopting a modeling method from learner to learner (MAGIL, 2000; SCHIMIDT & WRISBERG, 2005).

The treatment will consist of the following steps:

1) Warm-up: made of spacial movements in the wheel chair combined with active articular mobilization and auto passive with the objective of general warn-up. Duration: 10 minutes.

2) Stable non locomotor exercises: formed by active articular mobolization and auto passive with the objective of specific warm-up and developement of perception and action on stable positions such as seating and laying down and with body manipulation and objects close to the center of the body. Duration: 10 minutes

3) Unstable non locomotor exercises: made of active articular and auto passive movements with the objective of developing perception and action in unstable positions such as kneedown as well as with body manipulation and the objects at different distances from the body. Duration: 10 minutes.

4) Locomotor exercises: made of articular movements as well as rolling action, with the objective to develop perception and action with body in movement and with objects from different distances from the body. Duration: 10 minutes.

5) Warm down: relaxing exercises and streching with verbal description of relative content to the movement parameter developed at specific session. Duration: 10 minutes.

The 5 steps above consisted on a fixed structure of tasks aplyied in all sessions and the attentional movement parameters will be organized as follows:

1) Attentio

Primary Outcome(s)

The functional action studied will be the transport of a 1 liter jar filled with water, with two experimental condition: C1 to the front and C2 to the top.
The trunk coordenative behaviour and upper body will be described thru tridimencional cinematic sincronized with electromiography.
The variables are:
1) angular excursion
2) angular peak velocity
3) % movement time
4) linear peak velocity of the wrist, at coordenative axel X, Y and Z
5) time percentage for the peak at axel X,Y and Z
6) Total movement time

Electromiographic variables:
1) onset of movement
2) onset muscle duration
3) Muscle latency, calculated by the time interval btw initial movement and onset instant
4) previous activation, onset duration btw 500ms before the movement and the begining of movement.

It is expected that the group without medular lesion (SLM) will show differences at the coordenative behaviour at C1 and C2 conditions, confirming the relationship btw motor organization and functional demand of the task.

It is expected that the group with medular lesion will show differences in coordination in relation to the group without medular lesion at C1 and C2 experimental conditions.

It is expected that the attentional direction treatment for the amplitude variability parameters, velocity and tension at efector structures, positively interfers at the trunk and dominante superior limb coordenative behaviour of the group with medular lesion at experimental conditions C1 and C2.

Secondary Outcome(s)

1) Presentation of the results to members of the Paraná Handicap Association.

2) Submission of the results to international journals.
