Observation Of Shoulder Thermography On Patients With Post-stroke Shoulder Pain

Objective To observe shoulder skin temperature characteristics in hemiplegic patients and in patients with shoulder-hand syndrome, spasticity, and shoulder subluxation, and to explore whether the infrared thermal imaging can be used as an objective evaluation index for post-stroke shoulder pain.Methods Select86cases of stroke patients, using digital infrared thermal imaging temperature measurement system on hemiplegic patients and patients with shoulder-hand syndrome, spasticity and shoulder subluxation to observe their shoulder skin temperature characteristics. And compare skin temperature differences of shoulder between post-stroke shoulder pain patients and without post-stroke shoulder pain patients.Results86cases of stroke patients,73cases (84.9%) patients with abnormal asymmetric thermal image,70cases (81.4%) patients with the affected shoulder lower than the contralateral shoulder, In patients with shoulder-hand syndrome compared with patients without shoulder-hand syndrome, the difference has a significant meaning (P<0.05);spasm and non-spasm patients as well as shoulder subluxation and without shoulder subluxation patients, the differences are both no statistically significant (P>0.05). Comparison of shoulder pain and non-shoulder pain patients, differences has no significantly meaning (P>0.05).Conclusion Infra-red thermal imaging temperature measurement system can objectively reflect shoulder skin temperature changes in stroke patients.The skin temperature in patients with shoulder-hand syndrome is more asymmetric, but spasticity and shoulder subluxation can not significantly affect the results. Patients with subjective pain cannot be reflected by changes in skin temperature.
