For example, when holding a drill in space and attempting to control how deep it plunges, your biceps and triceps co-contract around your shoulder and elbow. In some conditions (eg brachial plexus injuries) pathologic co-contraction can limit function. ...Read more

Healing is from your body and not the cast. Tendon injury may take many wks to heal and so 1 wk is too early to tell. Close follow-up with the doc is recommended for reassessment/care. Good luck. ...Read more
