In my <strong>Neuromuscular Therapy<\/strong> practice near Boston, I find this often to be the original source of pain in the arms and the last problem spot to be corrected.<\/p>\n<p>Pain in the arms and hands originating from the shoulders is usually due to <strong>Trigger Points<\/strong> in the rotator cuff muscles, the pectoral and subclavius muscles, the latissimus dorsi and serratus anterior. There are lots of muscles who&#8217;s business it is to move the arms. Look at the illustration on the left to see just those that are in the front of the shoulder.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-2875\" title=\"latissimusdorsitrps1\" src=\"https:\/\/abbottcenter.com\/bostonpaintherapy\/wp-content\/uploads\/2010\/02\/latissimusdorsitrps1.jpg\" alt=\"latissimusdorsitrps1\" width=\"248\" height=\"158\" \/>Of all of these, I find the <strong>latissimus dorsi <\/strong>(part of it in yellow in the illustration) to be the most important for computer users because it moves the arm back and forth like when you&#8217;re moving the mouse. Trigger Points from the &#8220;lats&#8221; spread out over the lower part of the shoulder blade, down the side body and inside of the arm all the way down to the pinkie finger.<img loading=\"lazy\" decoding=\"async\" class=\"alignright size-full wp-image-2877\" title=\"serratus-anterior-trps1\" src=\"https:\/\/abbottcenter.com\/bostonpaintherapy\/wp-content\/uploads\/2010\/02\/serratus-anterior-trps1.jpg\" alt=\"serratus-anterior-trps1\" width=\"242\" height=\"155\" \/><\/p>\n<p>The <strong>serratus anterior <\/strong>moves the shoulder blade rather than the arm directly, but has a Trigger Point referral pattern similar to the lats.<\/p>\n<p>The four <strong>rotator cuff <\/strong>muscles move the arm and have multiple TrP patterns as illustrated below.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2872\" title=\"rotator-cuff-grp\" src=\"https:\/\/abbottcenter.com\/bostonpaintherapy\/wp-content\/uploads\/2010\/02\/rotator-cuff-grp.jpg\" alt=\"rotator-cuff-grp\" width=\"565\" height=\"150\" \/><\/p>\n<p>The last group, the<strong> pectorals and subclavius<\/strong> have similar TrP patterns.
