颈椎附近肌肉张力减退的儿童头部控制能力下降，无法保持直立的头部姿势。这些孩子经常使用外部头部支撑来保持头部直立。当他们的头部保持在适当的位置时，他们通常会发展出更多功能性的头部运动。先前的研究已经测量了使用头部支撑件的受试者的功能变化，但是没有研究施加在头部支撑件上的力。本研究观察受试者GMFCS V级和他们的功能技能，以及在4个月内施加在头部支撑上的力。一个力传感器连接到基地的头部支持被用来收集力的数据比较与课堂观察的儿童的功能表现的职业和物理治疗师。受试者在研究开始时活动度为1%的象限中表现出高达67%的增加。在随后几周的数据记录中，每例受试者施加大于头部重量的力的时间增加，峰值力大小增加。研究使用具有测量力的头部支撑的受试者的功能影响可以突出肌张力减退儿童的技能发展和进展的重要方面。
Children with hypotonia of the muscles near the cervical spine have reduced head control and are unable to maintain an upright head posture. These children often use an external head support to hold their heads upright. With their head held in the proper position, they often develop more functional head movements. Previous studies have measured functional changes to subjects using the head support but have not studied the forces exerted on the head support. This study observes subjects with GMFCS Level V and their functional skills alongside the forces exerted on the head support over a 4-month period. A force sensor attached to the base of the head support was used to collect force data to compare with classroom observations of the child's functional performance by occupational and physical therapists. Subjects showed an increase of up to 67% in quadrants where they previously had ¡1% activity at the beginning of the study. Each subject had increased time exerting forces greater than the weight of the head in later weeks of data recording as well as increased peak forces magnitude. Studying the functional impacts of subjects using a head support with measured forces can highlight important aspects of skill development and progress towards milestones for children with hypotonia.
