【脳卒中片麻痺を知る】肩の痛みの原因3選 ③外側上腕筋間中隔（がいそくじょうわんきんかんちゅうかく）の話・しびれ・下垂手（かすいしゅ）・二次的障害は改善の余地あり

[Summary] The lateral interbrachial septum is a slightly thick bundle of fascia located between the arm muscles (triceps brachii and brachialis). The radial nerve, an important nerve responsible for lifting the wrist, passes nearby. Why does pain and paralysis occur? When the muscles become stiff, the fascia (septum) also stiffens, compressing the nerve passing between them. Symptoms: Pain and numbness around the shoulder and back of the hand. Wrist drop: The wrist becomes limp and unable to be lifted. When exerting force, only the index finger stretches out. (The finger extensor muscles move, but the wrist muscles do not.) This is likely a "secondary problem" caused by muscle stiffness, rather than damage to the brain itself. ・If the problem is simply a compressed nerve, relaxing it can dramatically relieve pain and sometimes even restore wrist movement. ★Caution and Request ・Caring for this area is extremely delicate. ・Do not do it yourself or with your family: Rubbing too roughly can actually damage the nerve and worsen the pain. ・Consult a specialist: It's best to see a therapist (physiotherapist or occupational therapist) who is knowledgeable about anatomy and can manipulate fascia with a gentle touch. ・Show your therapist a video: Try asking your doctor if your case sounds like the one in this video. It's a shame to let unimpaired muscles, which have the potential to move, go dormant due to secondary issues. 0:20 Lateral Intermuscular Septum - What Patients Can Do 2:04 [Conclusion] The Relationship Between the Lateral Intermuscular Septum and the Radial Nerve 2:40 Numbness, Wrist Drop, and Index Finger Extension 6:14 Lateral Intermuscular Septum → Nerve Pinching Causes Heavy, Dull Pain 8:37 Caution!
