چکیده:
Objectives: Mirror therapy is a unique treatment with a touch of modality that is purported
to improve the motor function of the affected limb in individuals with hemiplegia. Previous
studies have focused on the neuro-physiological factors underlying the mechanism of the
clinical effect of this technique. The present study aims to understand the mechanism using
the rehabilitation method and neuro-occupation model as well as analyze the effects of mirror
therapy on the upper limb function of subjects with spastic hemiplegic cerebral palsy.
Methods: Single subject design known as withdrawal design was used by a convenience
sample of four subjects. The study involved three observational phases known as baseline,
treatment, and withdrawal phases that took place during a 10 week period. The study contained
a home-based mirror therapy protocol whereby the participants were instructed to do some
exercises on a daily basis. The improvement of the hand function of the hemiplegic side was
examined by Box and Block test along with two more activities including Threading Beads
and Stacking Rings.
Results: The ability to perform the Box and Block test, Threading Beads, and Stacking Rings
tended to remain steady in the baseline phase, whereas there was a noticeable improvement
during the treatment phase and a decline in the withdrawal phase.
Discussion: From the perspective of visual feedback neuro-occupation model, it could be
hypothesized that alterations to the sensory system caused by the mirror reflection of non
affected hand may have led to the destabilization of the sensory cortices that changed the

The present study aims to understand the mechanism using the rehabilitation method and neuro-occupation model as well as analyze the effects of mirror therapy on the upper limb function of subjects with spastic hemiplegic cerebral palsy.
Discussion: From the perspective of visual feedback neuro-occupation model, it could be hypothesized that alterations to the sensory system caused by the mirror reflection of non affected hand may have led to the destabilization of the sensory cortices that changed the participants’ intention, meaning, and perception, thereby improving the subject’s motor control.
Mirror therapy is a unique treatment with a touch of modality that is purported to improve the motor function of the affected limb in adults with hemiplegia following a cerebrovascular accident (stroke) [3] and children with spastic hemiparetic cerebral palsy [4, 5].
The Neuro-occupation model was used in this study to understand how upper limb motor function of children with spastic hemiplegic cerebral palsy was influenced by the mirror therapy.
Conclusion As far as the Neuro-occupation model is concerned, the contribution of the present study is that it leads to the conclusion that alterations to the visual sensory system caused by the mirror reflection of non affected hand may have led to destabilization of the sensory cortices which changed the participants' intention, meaning, and per- ception, thus improving the motor control.
