ObjectiveTo observe the effectiveness of core endurance isokinetic strength training on subacromial impingement syndrome (SAIS) rehabilitation.MethodsSAIS patients were selected from the Rehabilitation Department, Second Affiliated Hospital of Inner Mongolia Medical University from January 2018 to June 2019. The patients were randomly divided into observed group and control group by random number table method. The patients in control group were treated by keritherapy, cold, standard physiotherapy (PT) and exercise. At the same time, the patients in observed group were treated by core endurance isokinetic strength training combined with keritherapy, cold and standard PT. Both two groups were treated for 8 weeks. The patients were scored with visual analogue scale (VAS), Shoulder Pain and Disability Index (SPADI), Short Form 36 Healthsurvey Questionnaire (SF-36), flexor peak torque (FPT) and extensor peak torque (EPT) in pre and post treatment.ResultsA total of 59 patients with SAIS were enrolled. No exfoliating cases. There were 31 cases in the observed group and 28 cases in the control group. Pre-treatment, there were no significant difference in FPT, EPF, VAS, SPADI and SF-36 between the two groups (P>0.05). Post-treatment, there were no significant difference in EPT and VAS between the two groups (P>0.05); FPT [(62.65±10.17) N·m], SPADI [(53.18±10.25) points] and SF-36 [(35.54±11.39) points] in the observed group were significantly improved compared with the control group [(56.28±9.55) N·m, (61.05±9.41) points, (42.65±10.74) points] (t=2.473, 3.061, 2.460; P=0.014, 0.003, 0.017); FPT in both groups, and EPT in the observed group were improved compared with that of the pre-treatment (P<0.05); the EPT of the control group was improved compared with that of the pre-treatment, but the difference was not statistically significant (P>0.05); VAS, SPADI and SF-36 in the two groups were improved compared with those of the pre-treatment (P<0.05).ConclusionsCore endurance isokinetic strength training could improve the core stability of subacromial impingement syndrome patients. Satisfactory musculoskeletal dynamic chain plays a vital role in subacromial impingement syndrome rehabilitation.
Objective To explore the effects of intra-articular injection of platelet-rich plasma (PRP) on improving pain, joint function, and muscle strength of knee osteoarthritis (KOA). Methods From March 2017 to August 2019, 100 cases of KOA diagnosed and treated in the First Affiliated Hospital of Harbin Medical University were selected. They were divided into intervention group and control group with 50 cases in each group by random number table method. The patients in the intervention group were given intra-articular injection of PRP (5 mL/time, 1 time/week, 6 times in total) combined with isokinetic strength training (2 times/d, 3 d/week, for 12 consecutive weeks) treatment, and the patients in the control group were given intra-articular injection of sodium hyaluronate (2 mL/time, 1 time/week, for 12 consecutive weeks) combined with isokinetic strength training (2 times/d, 3 d/week, for 12 consecutive weeks). The incidence of adverse reactions during the treatment process and the clinical efficacy at 12 weeks of treatment and 6 months after treatment were recorded, and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scoring system was used to evaluate the knee joint function. When the isokinetic strength training instrument measured an angle of 90°/s, the knee joint flexor and extensor peak torque (PT), total work (TW), and average power (AP) were recorded. Results Forty-nine patients of each group completed the study. The between-group differences in WOMAC pain, stiffness, and joint function scores, and extensor and flexor PT, TW, and AP before treatment were not statistically significant (P>0.05). At 12 weeks of treatment and 6 months after treatment, the WOMAC scores of pain, stiffness, and joint function in the two groups were lower than those before treatment (P<0.05), and the extensor and flexor PT, TW, and AP were higher than those before treatment (P<0.05). Six months after treatment, the WOMAC scores of pain, stiffness, and joint function in the intervention group were lower than those in the control group (P<0.05), and the extensor and flexor PT, TW, and AP in the intervention group were higher than those in the control group (P<0.05). There was no significant difference in the effective rate between the two groups at 12 weeks of treatment (95.9% vs. 89.8%, P>0.05). The effective rate in the intervention group was higher than that in the control group 6 months after treatment (93.9% vs. 79.6%, P<0.05). No serious adverse reaction occurred in the two groups during the treatment. Conclusion Intra-articular injection of PRP can reduce pain, improve muscle strength, and improve joint function in patients with KOA, and the long-term effect is better than that of conventional drugs.
