ABSTRACT
Objective To observe the effects of short-term blood flow restriction (BFR) based on limb linkage training on cardiopulmonary endurance, lower limb muscle endurance and balance function of healthy people. Methods From December, 2019 to March, 2020, 20 healthy young people were randomly divided into control group (n = 10) and experimental group (n = 10). They accepted limb linkage training with the loading of anaerobic threshold (AT) according to the results of cardiopulmonary exercise test (CPET), 20 minutes a time, three times a week, for two weeks; while the experimental group wore 250 mmHg blood pressure training belt at the root of both thighs; the control group wore blood pressure training belt with no pressure. They were assessed with CPET, 6-minute walking test, wall squatting, seat test and functional reach test before and after training. Results After training, all the indexes improved in both groups (|t| > 2.321, P < 0.05), except functional reach test, the results of wall squatting and seat test were better in the experimental group than in the control group (t > 2.660, P < 0.05). Conclusion Limb linkage training combined with lower extremity BFR could further improve lower limb muscle endurance.

ABSTRACT
Objective:To compare the effects of observation to non-goal-oriented hand actions with video or pictures on speech recovery in stroke patients with chronic non-fluent aphasia. Methods:From January, 2016 to December, 2018, 30 patients with non-fluent aphasia after stroke were randomly divided into two groups. The control group (n = 15) repeated the verbs after watching picture, and the experimental group (n = 15) repeated the verbs after watching videos, for four weeks. They were assessed with Western Aphasia Battery (WAB) before treatment and every week after treatment. Results:Aphasia quotient (AQ) increased with time (F > 32.922, P < 0.001), but no significant difference was found between two groups at any time points (t < 0.699, P > 0.05). The interactive effect between time and group was significant (F = 6.398, P < 0.001), which suggested that AQ increased more in the experimental group than in the control group. Conclusion:For non-goal-oriented hand action observation, video observation maybe promote speech recovery in stroke patients with chronic non-fluent aphasia.
ABSTRACT
Objective:To explore the effects of action observation therapy on upper limb severe hemiplegia. Methods:From January to June, 2019, 40 patients with severe hemiplegia after stroke were randomly divided into control group (n = 20) and observation group (n = 20). Before routine rehabilitation training, the observation group watched the videos about activities and movements of arms and hands, and then were asked to imagine their affected arms and hands to complete these movements. The control group watched the videos of orderly geometric figures, letters and others without body and animals. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Motor Assessment Scale-Upper Extremities (MAS-UE) and modified Barthel Index (MBI) before and four weeks after treatment. Results:The scores of FMA-UE, MAS-UE and MBI improved after treatment (t > 2.854, P < 0.05), and improved more in the observation group than in the control group (F > 4.395, P < 0.05). Conclusion:action observation therapy can further improve upper limb motor function and activities of daily living in patients with severe hemiplegia after stroke.
ABSTRACT
Objective:To observe the clinical effect of low and medium intensity aerobic exercise combined with resistance exercise on patients with chronic kidney disease (CKD) complicated with sarcopenia. Methods:From 2018 to 2019, 11 elderly patients with CKD complicated with sarcopenia were enrolled in this study. All the patients received low and medium intensity aerobic exercise combined with resistance exercise intervention on the basis of regular internal medical treatment. Each exercise section included 30 to 50 minutes of aerobic exercise and 20 to 30 minutes of resistance exercise, and was conducted three times a week for twelve weeks. Before exercise, and 24 hours, six weeks and twelve weeks after exercise, the related indicators were measured. Results:No statistical difference in serum lipids and renal function indicators was found 24 hours after exercise, and six and twelve weeks post exercise (P > 0.05). Compared with pre-exercise condition, the reach in seat increased six weeks after exercise (P < 0.05); the appendicular skeletal muscle mass index, the grip strength index, the 6-meter walking speed, the peak oxygen uptake (VO2peak), the one-leg standing time and the reach in seat improved twelve weeks after exercise (P < 0.05). Compared with the results six weeks after exercise, the grip strength index, the 6-meter walking speed, VO2peak and the one-leg standing time improved twelve weeks after exercise (P < 0.05). Conclusion:Structured exercise training of low and medium intensity aerobic exercise combined with resistance exercise training would not worsen the renal function of patients with CKD complicated with sarcopenia; however, it could improve the muscle mass, strength and motor function of them.
