Objective:To compare postural stability and balance in different tasks between people with and without chronic, non-specific low back pain (CNLBP).Methods:Twenty patients with CNLBP formed the study′s CNLBP group, while 25 healthy counterparts were chosen as a normal group. Both groups were tested for their ability to standing on one leg with their eyes closed (the SOLEC test), for postural balance, for postural stability (PST), and had their limits of stability (LOS) time determined. The results were compared.Results:Compared to the normal group, the CNLBP group showed a significant difference in left-right weight-bearing in a bipedal semi-squat and in two-legged alternate standing. Shifting the center of gravity in bipedal standing revealed significant differences in LOS time, anterior-posterior stability index (APSI), mediolateral stability index (MLSI) and overall stability. In bipedal standing with the eyes closed there were significant differences in APSI, MLSI and OSI observed. On average, the CNLBP group had significantly shorter SOLEC and LOS times on the left and rear left sides.Conclusions:The CNLBP patients had some postural control deficits compared to their healthy counterparts and were less able to maintain static balance on their left leg and dynamic balance. They were less able to maintain postural balance in a bipedal semi-squat and during alternate leg standing. They are at greater risk of falling when moving the body′s center of gravity to the left or the rear left side.

Objective To observe and compare the effects of four methods of anesthesia in patients with anorectal surgery.Methods One hundred patients with anorectal surgery were equally divided into the group Ⅰ (low-dose epidural anesthesia),group Ⅱ (epidural anesthesia),group Ⅲ (caudal) and group Ⅳ (local anesthesia) based on a random draw principles,each group of 25 cases.The onset time of anesthesia,patient satisfaction,postoperative adverse reaction and hemodynamics were observed in the 4 groups.Results The anesthesia onset time in the group Ⅰ and group Ⅳ were (4.12 ±2.11) min and (3.69 ±1.11) min,significantly shorter than group Ⅱ and group Ⅲ ((10.34 ±3.10) min and (12.55±3.23) min,P＜0.05).Anesthesia satisfaction of four groups were 96.0％ (24/25),84.0％ (21/25),64.0％ (16/25) and 40.0％ (10/25),the differences among 4 groups were statistically significant (P＜0.05),and the anesthesia satisfaction of guoup Ⅰ was the best.Four groups of postoperative urinary retention difference were not statistically significant (P＞0.05),but the postoperative nausea and vomiting(n =3),referred pain (n =12),headaches (n=4) and other adverse events in the group Ⅳ were significantly higher than the other 3 groups(P＜0.05).Differences between-groups and inner-group were not statistically significant of the intraoperative mean arterial pressure,oxygen saturation and pulse rates of the four groups (P＞ 0.05).Conclusion Compare to other anesthetic methods,low-dose epidural anesthesia in anorectal surgery applications with faster onset time of anesthesia and anesthesia satisfaction results,it has litter adverse reactions and maintain stable hemodynamics body,worthy applications.
