Objective:To explore the effect of preoperative intensive functional training on the balance and functional recovery of patients with knee osteoarthritis (KOA) receiving total knee arthroplasty (TKA).Methods:Sixty KOA patients were randomly divided into an outpatient group, a home-based group and a control group, each of 20. Before their TKAs, both the outpatient and home-based groups underwent intensive functional training for 4 weeks, while the control group did nothing special. After the TKA, all received 4 weeks of standardized postoperative rehabilitation training. Before any training, after the 4 weeks of preoperative training and 4 weeks after the TKAs, all of the subjects performed the timed up and go test (TUGT), and their joint range of motion (ROM) was recorded. They also completed the 30-second chair stand strength test (30sCST), and the 6-minute walk exercise endurance test (6MWT). KOA osteoarthritis indices (WOMACs) were also recorded.Results:After the 4 weeks of preoperative training, significant differences were observed in the trajectory length, elliptical area and TUGT times of both the outpatient and home-based groups. Four weeks after the TKAs, significant differences were observed in all of the measurements in all three groups, but the results of the outpatient and home-based groups were significantly better than those of the control group, on average. After the 4 weeks of postoperative training, there were significant differences between the outpatient and home-based groups in terms of the average knee flexion angle, knee extension angle, 30sCST and 6MWT results. There were significant differences among the 3 groups in all of the measurements 4 weeks after the TKAs, with those of the two training groups showing significantly better results than the control group. The pain scores, stiffness scores, function scores and total WOMAC scores had improved significantly compared with the control group, but the average function and total WOMAC scores of the outpatient group (24.25±2.38) and (35.41±3.02) were then significantly superior to the home-based group′s averages.Conclusions:Intensive preoperative functional training conducted in an outpatient clinic or at home can significantly improve the balance, lower limb strength, exercise endurance and symptoms of KOA patients after TKA.

Objective:To observe any effect of low-frequency whole body resonant stimulation on the ba-lance and walking ability of hemiplegic stroke survivors.Methods:Sixty-six stroke survivors with hemiplegia were randomly divided into a low-frequency resonance training group, a high-frequency vibration training group and a control group, each of 22. All received routine exercise training at individualized intensities. All three groups underwent five 1-minute cycles of 7Hz, 15Hz or 1Hz stimulation twice a day, five days a week for eight weeks. Before and after the intervention, balance and walking ability were evaluated using the Berg Balance Scale, the timed up and go test and a 10m walking test. Step length, step frequency and step speed were also measured.Results:There were no significant differences among the three groups before the training. Afterward, significant improvement was observed in all of the groups in terms of all of the measurements. The average results of the low-frequency resonance training group were at that point significantly better than the other two groups′ averages, while the high-frequency vibration training group′s results were superior to those of the control group.Conclusion:Resonance training at 7Hz is the most effective in improving the balance and walking ability of stroke survivors with hemiplegia.

Objective:To explore the effects of aerobic exercise combined with resistance exercise on patients with diabetic peripheral neuropathy (DPN).Methods:A total of 60 patients with DPN in Sixth Affiliated Hospital of Nantong University from June 2018 to October 2019 were selected, and randomly divided into control group (20 cases), aerobic exercise group (20 cases) and combined training group (20 cases). Three groups all received the routine medication management and dietary guide. The control group had no other intervention. The aerobic exercise group received moderate intensity cycle ergometer, 40 min/time, once a day, three times a week. In addition to the moderate intensity aerobic exercise, patients in the combined training group conducted resistance exercise with elastic belt, 40 min/time, once a day, three times a week. The curative effect was evaluated after 12 weeks, which included fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), nerve conduction velocity and static balance function of eye-opened and eye-closed condition in Pro-Kin 254 balance assessment equipment.Results:Before exercise intervention, there were no significant differences in any measurements among the three groups (all P>0.05). After exercise intervention, the FBG, HbA1c, motor nerve conduction velocity of common peroneal nerve, sensory nerve conduction velocity of common peroneal nerve, sway length and area in the eye closed test of Pro-Kin254 balance assessment in the aerobic exercise group were significantly better than those in the control group[(6.26±0.28) vs. (6.76±0.68) mmol/L, (5.75±0.42)% vs. (6.48±0.37)%, (45.36±8.78) vs. (42.16±6.78) m/s, (38.75±8.14) vs. (35.45±8.34) m/s, (513±39) vs. (613±71) mm, (678±58) vs. (1 024±98) mm 2] (all P<0.05); the above indexes of the combined training group [(6.03±0.36) mmol/L, (5.27±0.35)%, (49.51±9.76) m/s, (42.87±7.18) m/s, (425±38) mm, (535±47) mm 2] were significantly better than those in the other two groups, the sway length and area in the eye open test of Pro-Kin254 balance assessment were also significantly superior to those in the other two groups [(316±21) vs. (395±18), (436±28) mm and (689±33) vs. (782±30), (824±70) mm 2] (all P<0.05). Conclusion:Aerobic exercise combined with resistance exercise can better improve the levels of blood glucose and HbA1c, increase nerve conduction rate and improve static balance ability compared with simple aerobic exercise in patients with DPN.

Objective To observe the clinical efficacy of acupoint injection plus nerve electrical stimulation in treating deglutition disorders after cerebral stroke. Method Seventy-seven patients with deglutition disorders after cerebral stroke were randomized into an electrical stimulation group of 24 cases, a hydroacupuncture group of 26 cases, and a comprehensive group of 27 cases, to respectively receive Vitalstim electrical stimulation, acupoint injection of Mecobalamin, and both of the treatments, 5 d as a treatment course, with 2-day interval between two courses, for 4 courses in total. The modified water-drinking test and Standardized Swallowing Assessment (SSA) were adopted to evaluate the therapeutic efficacy before the intervention, after 20-day treatment, and after 60-day treatment, and the therapeutic efficacies were compared. Result The modified water-drinking test and SSA scores were significantly changed in the three groups after 20-day treatment compared with that before the intervention, and the scores in the comprehensive group were superior to that of the electrical stimulation group and hydroacupuncture group. However, on the 60th day, the scores were equivalent among the three groups. Conclusion The Vitalstim electrical stimulation and acupoint injection of Mecobalamin both can produce certain treatment effects for deglutition disorders after cerebral stroke;the two methods can work in a synergistic way and can boost the improvement of swallowing function.
