Beyond diaphragmatic safety: distal motor function as the missing outcome in shoulder blocks

Key Points

• To investigate the importance of distal motor function as an outcome measure in shoulder block procedures.
• Conducted a randomized trial comparing interscalene block and combined infraclavicular-anterior suprascapular block.
• Focused on assessing distal motor function during the trial.
• Found that distal motor function is a critical outcome that may not be adequately assessed with current methods.
