The Impact

Background/Aims Strokes lead to different levels of disability. During the chronic stage, hemiparesis, spasticity and motor deficits may cause loss of functional independence. Mirror therapy aims to reduce deficits and increase functional recovery of the impaired upper limb. This study aimed to evaluate the effects of mirror therapy on upper limb spasticity and motor function, as well as its impact on functional independence in chronic hemiparetic patients. Methods In this quasi-experimental study, eight chronic hemiparetic patients (age 55.5 ± 10.8 years) were assessed to determine their degree of spasticity (Modified Ashworth Scale), level of upper limb motor function (Fugl-Meyer Assessment) and functionality (Functional Independence Measure). All participants received 12 sessions of mirror therapy delivered three times per week, over a period of 4 weeks. Participants were re-evaluated post-intervention and these results were compared to their pre-intervention scores to determine the impact of mirror therapy. Results A decrease in spasticity was observed, with significant improvements in shoulder extensors (P=0.033) and a significant increase in motor function (P=0.002). The therapeutic protocol adopted did not have a significant effect on functional independence (P=0.105). Conclusions Mirror therapy led to improvements in upper limb spasticity and motor function in chronic hemiparetic stroke patients. No effects on functional independence were observed. Further research with a larger number of patients is needed to provide more robust evidence of the benefits of mirror therapy in chronic hemiparetic stroke patients.

Chronic Hemiparetic Stroke

Despite the prevalence of hyperactive stretch reflexes in the paretic limbs of individuals with chronic hemiparetic stroke, the fundamental pathophysiological mechanisms responsible for their expression remain poorly understood. This study tests whether the manifestation of hyperactive stretch reflexes following stroke is related to the development of persistent inward currents (PICs) leading to hyperexcitability of motoneurons innervating the paretic limbs. Because repetitive volleys of 1a afferent feedback can elicit PICs, this investigation assessed motoneuronal excitability by evoking the tonic vibration reflex (TVR) of the biceps muscle in 10 awake individuals with chronic hemiparetic stroke and measuring the joint torque and electromyographic (EMG) responses of the upper limbs. Elbow joint torque and the EMG activity of biceps, brachioradialis, and the long and lateral heads of triceps brachii were recorded during 8 s of 112-Hz biceps vibration (evoking the TVR) and for 5 s after cessation of stimulation. Repeated-measures ANOVA tests revealed significantly ( P ≤ 0.05) greater increases in elbow flexion torque and EMG activity in the paretic as compared with the nonparetic limbs, both during and up to 5 s following biceps vibration. The finding of these augmentations exclusively in the paretic limb suggests that contralesional motoneurons may become hyperexcitable and readily invoke PICs following stroke. An enhanced tendency to evoke PICs may be due to an increased subthreshold depolarization of motoneurons, an increased monoaminergic input from the brain stem, or both.
