Abstract
The major device for locomotion is wheelchair in subjects with spinal cord
injury. How to improve their sitting balance would be an important program
for daily activities. EMG biofeedback has been used in stroke patients for
balance training, but it lacks this kind of study in patients with spinal cord injury.
The purposes of this project were to investigate the immediate and long-term
effects of back extensors-EMG biofeedback on reach in thoracic cord injured
patients.
There were 11 thoracic (T4-T12) completely injured male paraplegics with age
37.3±4.9 years old, height 167.6±4.7 cm, weight 62.2±9.0 kg, and duration 9.6±
5.3 years participated in this study. They received EMG biofeedback training
(Myoexerciser III, Verimed Inc, Florida) on back extensors (T5-6 and T11-12
paraspinal muscles) to obtain the followings: (1) the immediate effect by
performing 20 forward reaches, and (2) the long-term effect by performing 20
forward reaches per day for two weeks. The effects were assessed by having
subjects seated on a AMTI force plate to perform near (arm length), far (125%
arm length) and maximal reaches. The mean arm length of the participants was
69.8±2.0cm . The results indicated that: (1) Immediate effect of EMG
biofeedback on maximal reach (104.9±7.9 公分) was significantly increased. (2)
Long-term effect of EMG biofeedback on maximal reach (109.2±6.8 公分) was
significantly increased than that of immediate effect. (3) Kinetic analysis
revealed that both immediate and long-term (two-weeks) EMG biofeedback
training resulted in greater increases in anterior-posterior, right-left, and vertical
force shifting (Table 1), although the increase was not statistically significant. (4)
Kinematic analysis revealed that immediate EMG biofeedback training resulted
in decreases in reaction time and movement time, but long-term (two-weeks)
EMG biofeedback training resulted in a decrease in movement time. The
anticipatory time for anterior-posterior force was reduced, but the anticipatory
times for right-left, and vertical force shifting were increased (Table 2), although
the increases were not statistically significant.
