ABSTRACT
Objective:To study the judgment strategies of stroke patients facing different visual stimulus and the main factors affecting the mental rotation test results. Methods:From May to October, 2018, 15 stroke patients and 15 age-sex-education-matched healthy controls accepted standard software-based mental rotation tests with four kinds of visual stimulus: hand back, hand palm, Chinese characters and alphabets. Reaction time and response accuracy were recorded. All the subjects were assessed with Montreal Cognitive Assessment (MoCA), and the patients were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) additionally. Results:When hand back, hand palm and alphabets worked as visual stimulus, the response accuracy was less in the patients than in the controls (F > 7.027, P < 0.05). For all the tests, the reaction time was more in the patients than in the controls (F > 14.827, P < 0.001). The main effect of rotation angle was significant to reaction time when picture of hands as visual stimulus (F > 7.747, P < 0.001), while it was the least at 0°. The MoCA scores negatively correlated with reaction time in both groups (r < -0.375, P < 0.05), as well as the FMA-UE scores in the patients (r < -0.581, P < 0.05). Conclusion:Different types of visual stimulus may affect the judgment strategies and results of mental rotation test. Motor imagery ability is impaired for stroke patients, however, the basic reaction model maintains somehow.
ABSTRACT
Objective To explore the diagnosis and management of post-mastectomy sensory impairment and movement restriction. Methods A case was reviewed. Results She was diagnosed as radiation-induced brachial plexus injury with rotator cuff tear from the history,signs and tests.Her movement was improved and numbness was relieved after rehabilitation. Conclusion The sensory impairment after mastectomy is mainly caused by brachial plexus injuries,and needs to be dif-ferentiated from scapulohumeral periarthritis and rotator cuff tear when patients have shoulder movement restric-tion.
ABSTRACT
Objective To observe the effect of mirror therapy on persistent pain after breast cancer surgery,and to improve the quali-ty of life of the patients. Methods From September,2016 to June,2017,62 patients with persistent pain after breast cancer surgery were selected. They were randomly divided into control group(n=31)and mirror group(n=31).Both groups received routine re-habilitation,and the mirror group received mirror action in addition,30 minutes every time,five times a week for four weeks. The severity of pain was assessed with Numerical Rating Scale (NRS) before treatment, and four weeks,eight weeks and twelve weeks after treatment.The quality of life was assessed with European Organiza-tion for Research and Treatment of Cancer Quality of Life Questionnaire-30(EORTC QLQ-C30). Results Eight and twelve weeks after treatment,the NRS score was lower in the mirror group than in the control group (F>5.907,P<0.05).Twelve weeks after treatment,the total health status score of EORTC QLQ-C30 was higher in the mirror group than in the control group(t=2.128,P<0.05). Conclusion Mirror therapy could relieve the persistent pain after breast cancer surgery, and may help to improve the quality of life of the patients.
