To analyze the effect of virtual training based on somatosensory interaction technology in improving range of shoulder joint motion and muscle strength of patients with shoulder joint dysfunction.

From July 2017 to July 2019, 87 cases of shoulder joint dysfunction were divided into study group (n=44) and control group (n=43). The control group received routine rehabilitation training, while the study group received virtual training based on somatosensory interaction technology. The range of shoulder joint motion and muscle strength after different rehabilitation training were compared between the two groups.

After intervention, the ranges of motion of shoulder joint anteflexion, abduction, posterior extension, intorsion, and extorsion in the study group were (98.67±16.57)°, (106.37±9.59)°, (27.54±3.61)°, (55.86±7.51)°, (56.41±8.21)°, respectively, which were all significantly higher than those in the control group [(42.95±10.62)°, (37.95±5.94)°, (10.87±3.71)°, (23.81±6.81)°, (21.61±8.67)°] (all P<0.05). After intervention, there were 22 cases of grade 4 muscle strength and 10 cases of grade 5 muscle strength in the study group, which was significantly better that that in the control group [10 cases of grade 4 muscle strength and 3 cases of grade 5 muscle strength] (P<0.05).

Virtual training based on somatosensory interaction technology can effectively improve the range of shoulder joint motion, enhance the level of humerus muscle strength, and promote the recovery of shoulder function in patients with shoulder joint dysfunction, which has clinical research and popularization value.
