ABSTRACT
Objective:To study effects of balance and motor function of walking stability training guided by mirror neuron theory for stroke patients with hemiplegia.Methods:A total of 67 stroke with hemiplegia from January 2019 to June 2020 in Heze Municipal Hospital were divided into experimental group (34 cases) and control group (33 cases). All patients were given conventional rehabilitation training, the control group was given body weight support treadmill training, the experimental group was given mirror visual feedback therapy combined with body weight support treadmill training. The training time was 8 weeks. The body balance function, body motor function and life quality were evaluated by Fugl-Meyer Balance scale(FM-B), Berg Balance Scale(BBS), Tinetti Gait Analysis(TGA), Functional Ambulation Category scale(FAC), Stroke-Specific Quality of Life scale (SS-QOL) and compared before and after training between the two groups.Results:There was no significant difference in the score (classification) of FM-B, BBS, TGA, SS-QOL, FAC before training between the two groups( P>0.05). The score (classification) of FM-B, BBS, TGA, FAC after training were (11.35±1.32), (47.33±6.20), (9.32±1.12) points and (3.54±0.61)grades in the experimental group and (9.86±1.25), (42.14±6.35), (8.25±1.32) points and (3.15±0.54) grades in the control group. There were statistically significant of differences( t values were 2.768-4.741, P<0.05). The score of energy, activity ability, emotion, self-care ability, thinking, upper limb function and life quality total score of SS-QOL were (10.31±1.43), (21.46±4.45), (17.64±3.36), (17.32±3.15), (16.23±2.21), (159.11±16.34) points in the experimental group and (8.46±1.21), (17.32±3.24), (15.35±3.11), (14.78±2.32), (8.45±1.25), (13.45±1.54), (141.65±17.24) points in the control group. There were statistically significant of differences( t values were 2.893-7.096, P<0.05). Conclusions:Walking stability training based on mirror neuron theory help to restore limb balance and motor function, and improve life quality in stroke patients with Hemiplegia.
ABSTRACT
Objective To analyze human gait stability by acceleration signal at the head and lumbar under different walking conditions, and make comparison with parameters by the traditional COM (center of mass)-COP(center of pressure) method, so as to discuss the reliability of applying wearable sensors to analyze human gait stability. Methods The harmonic ratio (HR) parameter at the head and lumbar based on acceleration signal was applied to analyze gait stability of 18 healthy young adults under 3 walking conditions (footwear normal walking, barefoot normal walking and barefoot walking at different velocities), and the results were compared with the assessment results from the COM-COP method. Results Walking at normal velocity was most stable, with the maximum HR parameter. Compared with footwear walking, HR parameters were significantly decreased (P＜0.05) during barefoot walking, indicating that gait stability was reduced. The results were consistent with the assessment results from the COM-COP method. Considering the factors of walking velocity and footwear, the gait stability parameters obtained by the two methods showed a significant negative linear correlation (R2＞0.50). Lumbar HR parameter and COM-COP parameters showed a stronger linear correlation (R2＞0.65). Conclusions The application of acceleration signal-based analysis algorithm could effectively and reliably evaluate the stability of human gait, and acceleration at the lumbar was more sensitive than the head signal for analyzing gait stability.
ABSTRACT
Objective To compare the differences in gait characteristics and stability of women walking with or without sports bra.Methods Twelve women with C cup breast were required to walk on the treadmill (at the speed of 6 krn/h) with and without sports bras,respectively.Their gait parameters were collected by using Qualisys Track Manager high-speed infrared motion capture system.Results Compared with the bare-breasted condition,the maximum and minimum angles of the upper trunk were significantly smaller when subjects wearing the sports bra,the range of trunk flexion angles and trunk torsion angles were also relatively smaller,and the standard deviation of hip flexion angles during 10 gait cycles was obviously smaller.However,no differences were found in stride frequency between two breast support conditions.Conclusions Different breast support conditions have a significant influence on the upper trunk angle,trunk flexion angle and trunk torsion angle.Walking without bra will increase the range of trunk angle and deteriorate the walking stability.The stride frequencies under different breast support conditions have individual differences.
