Surface electrodes overestimate latissimus dorsi (LD) muscle activity during certain shoulder movements due to signal contamination. Intramuscular recordings revealed that deep muscles like erector spinae can interfere with accurate LD activity measurement.

Area of Science:

  • Biomechanics
  • Electrophysiology
  • Human Movement Analysis

Background:

  • Surface electrodes are commonly used for recording latissimus dorsi (LD) activity due to its superficial location.
  • The potential for signal contamination from deeper muscles, specifically erector spinae, when using surface electrodes on the LD has not been thoroughly investigated.

Purpose of the Study:

  • To determine the validity of using surface electrodes for recording latissimus dorsi (LD) muscle activity.
  • To assess potential signal contamination from adjacent deeper muscles during various shoulder tasks.

Main Methods:

  • Eight asymptomatic subjects performed isometric and dynamic shoulder tasks.
  • Intramuscular electrodes were inserted into the LD and adjacent erector spinae muscles.
  • Surface electrodes were placed over the LD concurrently with intramuscular recordings.

Main Results:

  • No significant difference in LD activity or activation patterns was found between surface and intramuscular electrodes during shoulder extension and adduction.
  • Surface electrodes significantly overestimated LD activity during shoulder flexion and abduction compared to intramuscular recordings (p<0.05).
  • Erector spinae muscles were identified as a source of crosstalk contamination affecting LD surface recordings.

Conclusions:

  • Surface electrode recordings of latissimus dorsi (LD) activity can overestimate muscle activation during shoulder tasks where LD is minimally involved.
  • Crosstalk from the erector spinae muscle is a significant factor influencing the accuracy of surface electrode recordings of LD activity.
  • Careful consideration of electrode placement and potential confounding muscle activity is necessary for accurate LD electrophysiological assessment.
