Objective To investigate the relationship between gait spatiotemporal parameters and balance function in stroke hemiplegic patients. Methods From September, 2018 to March, 2020, 76 stroke hemiplegic patients (38 in Brunnstrom Ⅳ and V, respectively) were assessed balance function with Active Balancer EAB-100 and Star Excursion Balance Test (SEBT), and gait parameters of speed, cadence and asymmetry, named step length asymmetry ratio (SLA), swing time asymmetry ratio (SWTA), stance time asymmetry ratio (STA), maximum flexion angle ratio (MFA) of hip and knee. The correlation among gait parameters and balance function was analysed. Results The balance and gait parameters were better in those in Brunnstrom V than in Brunnstrom Ⅳ (|t| > 2.268, P < 0.05). The speed and cadence correlated with the most balance indexes (|r| > 0.335, P < 0.05). SLA correlated with SEBT in Brunnstrom Ⅳ patients (r = -0.467~-0.613, P < 0.01), while it correlated with medial-lateral (M-L) stability limits in Brunnstrom V patients (r = -0.356, P = 0.028). SWTA correlated with stability limit of Anterior-Posterior (A-P) (r = -0.335, P = 0.040) and M-L (r = 0.510, P = 0.001), and most of SEBT (r = -0.330~ -0.445, P < 0.05) in Brunnstrom Ⅳ patients. MFA of hip and knee correlated with balance indexes in Brunnstrom Ⅳ patients (|r| > 0.326, P < 0.05), while MFA of knee correlated with most balance indexes in Brunnstrom V patients (r > 0.329, P < 0.05), and MFA of hip correlated with A-P stability limit (r = 0.369, P = 0.023). Conclusion Both speed and cadence of steps can well respond to the balance function in stroke hemiplegic patients. For the asymmetry, it is related with balance in patients with poorer recovery.

Objective To explore the effect of continuous nursing intervention on limb function and nursing quality after proximal femoral nail antirotation (PFNA) internal fixation for femoral intertrochanteric fracture in the elderly. Methods From February, 2017 to November, 2018, 100 elderly patients with femoral intertrochanteric fracture who underwent PFNA internal fixation in our hospital were randomly divided into control group (n = 50) and observation group (n = 50), who accepted routine nursing and continuous nursing respectively for three months. They were assessed with Harris score and visual analogue scale for pain (VAS) before and after the intervention. The postoperative nursing effect was compared. Results The Harris score increased in both groups after the intervention (t > 45.98, P < 0.001), and increased more in the observation group than in the control group (t = 15.03, P < 0.001). The VAS score decreased in both groups after the intervention (t > 16.33, P < 0.001), and decreased more in the observation group than in the control group (t = 9.749, P < 0.001). The effect of nursing was better in the observation group than in the control group (Z = -2.272, P = 0.023). Conclusion Continuous nursing intervention can significantly improve the limb function and nursing satisfaction of elderly patients with femoral intertrochanteric fracture after PFNA.

Objective To use World Health Organization Family International Classifications (WHO-FICs) to explore the framework and approaches of development and research of guidelines of rehabilitation at levels of policies, community and services.Methods The important documents and tools of rehabilitation at international level, including United Nations Convention on the Rights of Persons with Disabilities, WHO World Report on Disability, Community-based Rehabilitation Guideline, Rehabilitation in Health Service System, and International Classification of Diseases (ICD), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHI) of WHO-FICs, had been discussed.Results The framework, classifications, diagnosis and description of diseases and functioning, coding, intervention and functioning evaluation based on ICD-11, ICF and ICHI-β-2 had been established for development and implementation of rehabilitation guidelines and Cochrane rehabilitation.Conclusion The framework and systematic approaches of ontology, classification, terminology, coding, diagnosis and description of diseases and functioning, interventions and evaluations for the development and implementation of rehabilitation guidelines had been developed.
