ABSTRACT
Objective:To study the effect of chair inclination angles forward on sit-to-stand time and muscle activation of lower extremities in stroke patients with hemiplegia. Methods:From January to August, 2019, 15 stroke patients with hemiplegia finished five times sit-to-stand at seat slope 0°, 10° and 20° forward. The time, and surface electromyogram (sEMG) signals of rectus femoris, hamstrings, anterior tibialis and peroneus muscle were recorded. Results:The total EMG peak, root mean square and integrated electromyography (iEMG) of all the muscles decreased at seat slope 10° and 20° forward compared with those at 0° (F > 4.530, P < 0.05). The time decreased at seat slope 20° forward compared with that at 0° (P < 0.05). Conclusion:Seat inclination forward at some angles may improve the sit-to-stand performance in stroke patients with hemiplegia.
ABSTRACT
Objective:To explore the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function in hemiplegic patients after stroke. Methods:From August, 2018 to July, 2019, 60 patients with hemiplegia after stroke were randomly divided into control group (n = 30) and observation group (n = 30). Both groups received conventional treatment. The observation group accepted 5 Hz rTMS to ipsilesional hemisphere premotor areas for three weeks. The control group received sham stimulation. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Brunnstrom stages, modified Ashworth Scale (MAS), modified Barthel Index (MBI) and Wolf Motor Function Test before and after treatment. Results:Two patients dropped in the control group. After treatment, the scores of FMA-UE, MBI and Wolf Motor Function Test improved in both groups (|t| > 3.686, P < 0.01), and the difference values of FMA-UE and Wolf Motor Function Test before and after treatment were more in the observation group than in the control group (|t| > 2.119, P < 0.05). Conclusion:High-frequency rTMS to ipsilesional hemisphere premotor areas could improve the recovery of upper limb and hand motor function in hemiplegic patients after stroke.
ABSTRACT
Objective:To explore the effects of robot-assisted therapy combined with mirror therapy (MT) on upper limbs in patients with hemiplegia after stroke. Methods:From January, 2017 to June, 2018, 56 patients with hemiplegia after stroke were randomly divided into control group (n = 28) and observation group (n = 28). The control group received conventional therapy, and the treatment group received robot-assisted therapy combined with MT, additionally. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), Functional Independence Measure (FIM) and modified Barthel Index (MBI) before and four weeks after treatment. Results:Four weeks after treatment, the scores of FMA-UE, WMFT and MBI were better in both groups (t > 2.959, P < 0.05), and were better in the observation group than in the control group (t > 4.732, P < 0.001). Conclusion:Robot-assisted therapy combined with MT could improve the function of upper limb and activities of daily living in patients with hemiplegia after stroke.
