Antagonist Activation Measurement at the Ankle Using High-density and Bipolar Surface EMG in Chronic Hemiparesis

NCT06099132 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 12

No results posted yet for this study

Summary

In chronic hemiparesis, abnormal antagonist muscle activation in the paretic lower limb contributes to impair ambulation capacities. A biased estimate of antagonist muscle activation when using surface bipolar EMG compared with high-density (HD) EMG has been previously reported in healthy subjects. The present study compares muscles cocontraction at the paretic ankle estimated with a pair of and multi-channel surface EMG.

Conditions

  • Stroke
  • Muscle Hypertonia
  • Spasticity, Muscle

Interventions

DIAGNOSTIC_TEST

Electromyographic measurements

HD and bipolar EMG were assessed from gastrocnemius medialis (GM), soleus (SO) and tibialis anterior (TA) at seated position, ankle at 0°, during isometric submaximal effort and maximal effort, knee flexed (90°) and knee extended (0°)
