ABSTRACT
Objective:To investigate the clinical effect of proprioceptive trainning on patients after anterior cruciate ligament reconstruction. Methods:From March, 2017 to September, 2018, 30 patients after anterior cruciate ligament reconstruction were randomly divided into control group (n = 15) and experimental group (n = 15). All the patients received routine rehabilitation for eight weeks after operation. Then, the control group received routine rehabilitation, while the experimental group received proprioceptive trainning in addition, for eight weeks. They were assessed with Lysholm score, Isokinetic Testing and Training System, and Dynamic Balance Tester eight and 16 weeks of training. Results:Lysholm score increased in both groups after treatment (t > 16.687, P < 0.001), with decrease of error of knee flexion in 15°, 45° and 75° (t > 2.433, P < 0.05), and speed of centre of gravity moving with eyes closed on stable and unstable floors (t > 2.444, P < 0.05). Compared with the control group, Lysholm score was more (t = 4.150, P < 0.05), errors of knee flexion in 15° and 45° were less (t > 2.710, P < 0.05), and speed of centre of gravity moving with eyes closed on unstable floors was less (P<0.05) in the experimental group. Conclusion:Proprioceptive trainning is effective on proprioception and function of knee after anterior cruciate ligament reconstruction, to improve postural control.
ABSTRACT
<p><b>BACKGROUND</b>Patients with pelvic fractures are often treated in hospitals without the capacity to implement an open reduction internal fixation (ORIF). This often leads to pelvic malunion in patients with unstable pelvic fracture, shock or even death due to uncontrollable pelvic hemorrhage and unstable hemodynamics. This study explored the role of early external fixation (within 7 days) for patients with unstable pelvic fractures.</p><p><b>METHODS</b>A retrospective analysis was conducted on 32 patients with unstable pelvic fractures treated with early external fixation from January 2005 to January 2010 (Tile type B: 18 cases; C: 14 cases). The study comprised 28 males and 4 females, with a mean age of (32 ± 8) years (range, 21-56 years). Of these patients, 22 were treated with emergency pelvic external fixation and 10 were treated with external fixation within 1-7 days. Fifteen cases suffered traumatic hemorrhagic shock. A statistical analysis was conducted to compare fluid infusion and blood transfusion volumes within the first 24 hours of these shock patients with another cohort of patients treated without early external fixation from January 1993 to January 1998.</p><p><b>RESULTS</b>The average follow-up was (34.7 ± 14.6) months (range, 6-66 months). Six to eight weeks after external fixation, patients could walk with crutches; by 12 weeks, external fixation was removed and all fractures had healed. Seven patients presented with sequelae, including 3 patients with long-term lumbosacral pain, 3 patients with erectile dysfunction and 1 patient with Morel-Lavallee lesion and other complications. The 15 shock patients in this study (2005-2010 group) required significantly lower volumes of fluid infusion and blood transfusion (P(fluid) = 0.000; P(transfusion) = 0.000) as compared to the 1993-1998 cohort.</p><p><b>CONCLUSIONS</b>The early application of external fixation in unstable pelvic fracture patients positively affects hemodynamic stability, with outstanding efficacy as a final fixation option for unstable pelvic fractures.</p>
