AIM
To investigate whether head and neck proprioception and motor control could be compensatory enhanced by long-term vision loss or impairment.
METHODS
Individuals who were blind, low vision or sighted were included in the study, which would undergo the head repositioning test (HRT). The constant error (CE), absolute error (AE), variable error (VE) and root mean square error (RMSE) of each subject were statistically analyzed. Data were analyzed using the SAS 9.4. Tukey-Kramer for one-way ANOVA was used for comparison of blind, low vision, and sighted subjects, as well as to compare subjects with balanced vision, strong vision in the left eye and strong vision in the right eye. Independent sample -test was used to compare subjects with congenital blindness and acquired blindness, as well as left and right hand dominance subjects.
RESULTS
A total of 90 individuals (25 blind subjects, 31 low vision subjects, and 34 sighted subjects) were included in the study. Among the blind subjects, 14 cases had congenital blindness and 11 cases had acquired blindness. Among the blind and low vision subjects, 21 cases had balanced binocular vision, 17 cases had strong vision in the left eye and 18 cases had strong vision in the right eye. Among all subjects, 11 cases were left hand dominance, and 79 cases were right hand dominance. There were significant differences in AE, VE, and RMSE in head rotation between blind, low vision, and sighted subjects (<0.01), in AE, VE, and RMSE between blind and sighted (<0.01), and in VE and RMSE between low vision and sighted (<0.05). No significant difference between blind and low vision (>0.05). Significant differences in CE and AE of head right rotation and CE of general head rotation between congenital and acquired (<0.05). No significant differences between left and right hand dominance and in balance or not of binocular vision (>0.05).
CONCLUSION
Long-term vision loss or impairment does not lead to compensatory enhancement of head and neck proprioception and motor control. Acquired experience contributes to HRT performance in the blind and has long-lasting effects on plasticity in the development of proprioception and sensorimotor control.
目的
探讨长期视力丧失或受损是否会代偿性增强头颈部本体感觉和运动控制能力。
方法
纳入失明、视力低下或视力正常的个体进行研究，这些个体将接受头部重新定位测试（HRT）。对每个受试者的恒定误差（CE）、绝对误差（AE）、可变误差（VE）和均方根误差（RMSE）进行统计分析。数据采用SAS 9.4进行分析。单向方差分析的Tukey-Kramer法用于比较失明、视力低下和视力正常的受试者，以及比较双眼视力平衡、左眼视力强和右眼视力强的受试者。独立样本t检验用于比较先天性失明和后天性失明的受试者，以及左右手优势的受试者。
结果
本研究共纳入90名个体（25名失明受试者、31名视力低下受试者和34名视力正常受试者）。在失明受试者中，14例为先天性失明，11例为后天性失明。在失明和视力低下受试者中，21例双眼视力平衡，17例左眼视力强，18例右眼视力强。在所有受试者中，11例为左手优势，79例为右手优势。失明、视力低下和视力正常的受试者在头部旋转的AE、VE和RMSE方面存在显著差异（<0.01），失明和视力正常的受试者在AE、VE和RMSE方面存在显著差异（<0.01），视力低下和视力正常的受试者在VE和RMSE方面存在显著差异（<0.05）。失明和视力低下之间无显著差异（>0.05）。先天性和后天性在头部右旋的CE和AE以及头部总体旋转的CE方面存在显著差异（<0.05）。左右手优势以及双眼视力是否平衡之间无显著差异（>0.05）。
结论
长期视力丧失或受损不会导致头颈部本体感觉和运动控制的代偿性增强。后天获得的经验有助于盲人的HRT表现，并对本体感觉和感觉运动控制发展中的可塑性产生长期影响。
