[Postural biofeedback and locomotion reeducation in stroke patients]

Area of Science:

• Neurorehabilitation
• Biomechanics
• Physical Therapy

Background:

• Hemiparetic gait is a common impairment following stroke, significantly impacting patient mobility and independence.
• Conventional physical therapy aims to improve motor function, but specialized interventions may offer additional benefits for gait recovery.

Purpose of the Study:

• To compare the effectiveness of conventional physical therapy alone versus physical therapy combined with a specialized balance retraining program for improving gait in post-acute hemiparetic patients.

Main Methods:

• A randomized controlled trial involving 26 post-stroke hemiparetic patients within 3 months of onset.
• Patients were assigned to either conventional physical therapy or therapy with a specialized balance retraining program using a forceplate system (BPM Monitor).
• Gait spatiotemporal parameters and clinical measures were assessed at baseline, at the start of walking, and 30 days later.

Main Results:

• Both groups showed significant improvements in clinical scores and gait velocity, except for spasticity.
• Gait patterns improved in both groups, with a notable increase in single stance duration on the paretic limb.
• The experimental group, utilizing balance retraining, demonstrated a significantly greater improvement in the duration of double stance on the paretic limb compared to the control group.

Conclusions:

• Conventional physical therapy and specialized balance retraining both contribute to gait improvement in hemiparetic patients.
• Visual biofeedback from a forceplate system enhances anticipatory equilibrium and specific aspects of gait, particularly the double stance phase.
• Specialized balance retraining programs may offer superior benefits for specific gait parameters in stroke survivors.
