The pattern of muscle paralysis and paresis in the upper limb has been studied in 31 children with poliomyelitis. The incidence of involvement of the upper limb alone is the same as of the upper and lower limbs together, and of the spine and upper limb. The left arm was more commonly affected than the right. The muscle most frequently paralysed was the deltoid. When complete paralysis of the whole deltoid occurred and was associated with paralysis of the rotator cuff muscles, the shoulder often subluxed downwards. The next most commonly affected muscles were the elbow flexors and extensors. In the hand the opponens pollicis was most often involved. As far as the spinal segments are concerned, C5 involvement was usually associated with paralysis and C7 with paresis.
对31例小儿麻痹症患儿上肢肌肉麻痹和轻瘫模式进行了研究。仅上肢受累的发生率与上下肢同时受累以及脊柱和上肢受累的发生率相同。左臂比右臂更常受累。最常发生麻痹的肌肉是三角肌。当整个三角肌完全麻痹并伴有肩袖肌群麻痹时，肩部常向下半脱位。其次最常受累的肌肉是肘部屈肌和伸肌。在手部，拇对掌肌最常受累。就脊髓节段而言，C5受累通常伴有麻痹，C7受累伴有轻瘫。
