目的 研究学龄前生长痛患儿与非生长痛儿童下肢痛阈是否存在差异,为明确生长痛的发生机制提供参考依据。方法 采用痛觉传感器,测量135名生长痛患儿和133名非生长痛儿童下肢相关部位的压痛阈,采用非参数秩和检验与χ2检验比较两组儿童痛阈值和压痛点人数。结果 生长痛儿童股骨外上髁、胫骨内侧髁、胫骨外侧髁与髌骨中间处痛阈值与对照组差异具有统计学意义(P<0.05);压力水平<3 kg/cm2时,生长痛组胫骨内侧髁、胫骨外侧髁与髌骨中间处压痛点数目与对照组差异具有统计学意义(P<0.05)。结论 生长痛患儿更容易产生膝关节周围疼痛并出现相应体征。
Abstract
Objective To investigate the difference of lower pain threshold between children with and without growing pains,and to provide evidence for the mechanism research of growing pain. Methods The pain threshold of 135 children,aged 3~7 years old with growing pains and 133 controls were measured by use of a dolorimeter with pressure applied to lower limbs associated with the usual region of pain in children with growing pains.Non-parametric rank test and Chi-square tests were used to compare the pain threshold and number of tender points in patients and controls. Results The pain thresholds in lateral epicondyle of femurus,medial condyle of tibia,lateral condyle of tibia and medial patella in children were clower than those of control group(P<0.05);children with growing pains had a significantly greater number of tender point on lateral epicondyle of femurus,medial condyle of tibia,lateral condyle of tibia and medial patella in response to an applied pressure below 3 kg/cm2(P<0.05). Conclusion Children with growing pains are more likely to feel pain in knee joint,and appear correspondent clinic sign.
