Objective To study the influence of center of gravity excursion in standing on function outcome of stroke patients.Methods46 stroke patients were assessed with static posturography in standing,Fugl-Meyer Balance Scale,Barthel Index and the time in hospital.The patients were divided into 2 groups according to posturography results:center of gravity was inclined to the normal side (normal group),center of gravity was inclined to the hemiplegia side (hemiplegia group).ResultsThe ability of balance,walking and activity of daily living(ADL)of the normal group patients were better than that of the hemiplegia group patients,and the in-hospital time was shorter (P<0.001).ConclusionThe center of gravity excursion in standing is highly correlated with functional outcome of stroke patients.

ObjectiveTo study the correlations between Berg balance scale (BBS) and balance subscale of Fugl-Meyer test (FM-B), and evaluate their practicability for assessing balance function of patients after stroke.Methods68 stroke inpatients were assessed with BBS, FM-B and BPM before training. After training they were re-assessed by the same researcher. The parameters of BPM were sway index, sway tract length and area. The patients were assessed twice with eye opened and eye closed respectively.ResultsThere was no significant difference in the score of FM-B between the first assessment and after training (P>0.05), while that of BBS and BPM after training were better than before the training (P<0.001). There was moderate correlation between FM-B and BBS (r=0.517,P<0.001), but there was no correlation between FM-B and BPM (r=-0.074～-0.247,P>0.05). There was moderate negative correlation between BMP and BBS (r=-0.410～-0.587,P<0.01).ConclusionBBS and BPM are good tools for assessing balance function of stroke patients; FM-B shows low sensitivity and is not suitable for assessing stroke patients.

Objective To study the effects of robot-assisted therapy combined with electromyographic biofeedback (EMGBF) on upper limb function after stroke.Methods Thirty acute stroke patients were randomly divided into two groups of 15.The patients in the control group received a conventional rehabilitation program and EMGBF.The patients in the treatment group received robot-assisted therapy for 30 minutes daily,6 days a week for 3 weeks combined with EMGBF on the basis of the conventional rehabilitation program.Upper limb motor function and ability in the activities of daily living (ADL) were assessed with the Fugl-Meyer upper extremity assessment (FMA) and a functional independence measure (FIM) before treatment,at 3 weeks and 3 months after treatment.Results After treatment the FMA and FIM scores of both groups were significantly better than before treatment.At 3 weeks after treatment there was no significant difference in the average FMA scores of the two groups,but at 3 months after treatment the patients in the treatment group had significantly better scores.No significant differences in FIM scores were observed at 3 weeks or 3 months.Conclusions Robot-assisted therapy combined with EMGBF can improve upper limb motor function significantly in acute stroke patients,and more effectively than EMGBF.But no significant advantage in improvement in ADL performance was observed with Robot-assisted therapy combined with EMGBF over EMGBF.

Objective To explore the effect of vaginal pressure feedback combined with pelvic floor muscle resistant training on stress urinary incontinence (SUI). Methods 125 women with SUI in our hospital from February, 2014 to May, 2015 were randomized into control group (n=65) and experimental group (n=60). The control group took Kegel exercise, which asked for patients to contract their pelvic floor muscles, while the experimental group first received biofeedback electrical stimulation for 20 minutes with XFT-2002 pelvic floor stimula-tor, then instructed the patients to contract their pelvic floor muscles and pressed the pneumatic probe which placed in vagina according to the voice navigation of XFT-0010 pelvic floor muscle stimulator after they learnt the contraction skill. Both groups received training with 10 seconds' contraction and 10 seconds' rest 30 minutes per day for 30 days in total. They were assessed by GRRUG and International Consulta-tion Incontinence Questionnaire-UI Short Form (ICIQ-SF). Results After treatment, the muscle strength of the pelvic floor (t=-3.570) and the scores of ICIQ (t=4.198) improved significantly in both groups (P<0.01), and was higher in the experimental group than in the control group (t=6.833, t=-2.445, P<0.01), as well as the therapeutic efficiency (Z=63.954, P<0.001). Conclusion Vaginal pressure feedback com-bined with pelvic floor muscle resistant training can further improve stress urinary incontinence in women.

ObjectiveTo study the effect of partial body-weight support and treadmill training in subacute stroke patients.Methods40 stroke patients were randomly arranged into 3 groups: group A (n=14) accepted 8 weeks of routine physical therapy, group B (n=13) accepted additional 6 weeks partial body-weight support and treadmill training at the 3rd week, group C (n=13) accepted additional 3 weeks partial body-weight support and treadmill training at the 6th week. The patients were evaluated with Fugl-Meyer Assessment of Physical Performance(FMA), Barthel Idex(BI) and the Berg Balance Scale(BBS). ResultsThe functional outcome of the initial evaluation with FMA, BI and BBS were no-significantly different, 8 weeks later, that of group B were better than that of group A and group C (P<0.05～0.01), and that of group C were better than that of group A (P<0.05).ConclusionEarly treatment of partial body-weight support and treadmill training can help to improve the lower extremities function.
