Abstract

Objective: To investigate the application effect of adjustable ankle foot orthosis combined with functional training in improving the function of ankle joint in patients with traumatic brain injury. Methods: A total of 60 patients with traumatic brain injury admitted to Jiangbin Hospital from February to December 2022 were selected as the research objects and randomly divided into an observation group and a control group. In the observation group there were 20 males and 10 females, and the average age was (39.10±10.98) years; and in the control group there were 17 males and 13 females, and the average age was (36.80±10.55) years. The patients in the control group underwent the routine functional training according to the rehabilitation treatment process, and patients in the observation group were given an adjustable ankle-foot orthosis on the bases of routine functional training. The indexes of lower limb plantar flexor muscle spasm, ankle plantar flexion and varus angle were compared between the two groups.Results: After 8 weeks of treatment, the lower limb plantar flexor muscle spasm(modified Ashworth spasm scale) scores in the observation group were lower than those in the control group, and the ankle plantar flexion and varus angle in the observation group were smaller than those in the control group, and the difference was statistically significant(P<0.01). Conclusion: Application of combination of adjustable ankle foot orthosis with functional training can improve ankle joint function in patients with traumatic brain injury.

颅脑损伤是常见损伤之一。外科手术是治疗颅脑损伤的常用方法,能够减轻患者的脑组织损伤,有效改善其病情。但术后多数患者存在不同程度的下肢运动功能障碍,尤其是踝关节跖屈、内翻以及小腿三头肌痉挛,不仅影响患者康复进程,影响下肢运动功能恢复,还导致患者日常生活能力下降,生活质量降低。如何有效改善颅脑损伤患者的踝关节功能,提高下肢运动功能,提高日常生活质量一直是康复研究的重点。本研究旨在探讨可调踝足矫形器联合功能训练在改善颅脑损伤患者踝关节功能中的应用。

1 对象与方法

1.2 方法

对照组患者在常规药物治疗的基础上,按康复治疗流程进行常规功能训练。2次/d,每次45 min。观察组患者在此基础上使用可调踝足矫形器治疗。将可调踝足矫形器关节处活动范围调至大于患者踝关节最大矫正角度约5~10°,穿戴可调踝足矫形器后再调整两侧可调型拉带至患者踝关节最大矫正位,将粘带固定,再将定位枕放置于患者膝关节正下方,使患者静息时膝、髋关节处于5°弯曲。可调踝足矫形器每天穿戴3次,每次60 min。观察患者下肢肌张力及踝关节跖屈、足内翻角度变化。

1.3 评价指标

通过踝关节跖屈与内翻角度、下肢跖屈肌痉挛程度评价患者踝关节功能改善状况。本研究在康复治疗8周后评估患者踝关节跖屈与内翻程度和下肢跖屈肌痉挛程度。

1.3.1 踝关节跖屈与内翻角度

患者仰卧位,置量角器轴心位于踝中点下方约2.5 cm,固定臂平行腓骨长轴,移动臂平行第5跖骨,所测角度减去90°即得踝关节跖屈角度。患者仰卧位,量角器轴心置于跟骨外侧面,固定臂平行胫骨长轴,移动臂平行足跟跖面,所测角度减去90°即得踝关节内翻角度。

1.3.2 下肢痉挛评分

使用改良Ashworth量表来评定跖屈肌张力,分为0、1、1+、2、3、4共6个等级[1]

1.4 统计学方法

采用SPSS 22.0软件进行分析,计数资料用百分比(%)描述,比较采用χ2检验。计量资料用±s描述,比较采用t检验。非正态分布的计量资料以M(P25,P75)表示,比较采用秩和检验。P<0.05为差异有统计学意义。

3 讨论

矫形器技术已成为现代康复治疗技术的重要组成部分,越来越多的临床应用证明了其疗效显著[1-4]。徐辰辉等[5]研究发现,应用可调式多功能踝足矫形器可促进早期脑损伤足下垂者的下肢功能增强以及步行速度和平衡状态改善,促进了患者预后的改善。Katarzyna等[6]提出在颅脑损伤康复过程中应注重多领域、多模式介入。罗曼丽[7]对颅脑损伤康复治疗发展趋势做了深入研究后提出需优化康复治疗体系,建成全科型康复治疗系统。Novak等[8]认为矫形器及人工牵伸是更有效的治疗,可用于纠正踝关节跖屈挛缩。
本研究结果显示,观察组颅脑损伤患者的踝关节跖屈与内翻的程度在可调踝足矫形器联合功能训练治疗8周后有明显改善,说明可调踝足矫形器联合功能训练能有效改善踝关节功能,延缓踝关节异常模式进展。颅脑损伤后患者运动神经功能受损,踝关节控制调节能力失调,小腿三头肌痉挛,胫前肌收缩无力,易出现踝关节跖屈内翻的畸形状态。应用可调踝足矫形器可通过持续性控制和静止性反射抑制来抵抗肌痉挛,从而改善足内翻和足下垂。因此,可调踝足矫形器联合功能训练可预防腓肠肌及比目鱼肌痉挛,从而改善足下垂。
由于颅脑损伤后中枢神经系统传导受损,踝关节周围的肌肉和韧带组织失去正常神经支配,易出现踝关节跖屈、内翻等功能异常[9]。一旦出现足下垂和足内翻,对患者的步行功能的恢复将会造成极大的影响。另一方面中枢神经受损导致下运动神经元功能过度释放,患者存在不同程度的肌张力增高现象,若不及时给予有效治疗可能导致患肢出现永久性高肌张力,并伴有关节挛缩与运动功能障碍等现象,进而导致患者肢体无法正常负重,直接影响患肢的平衡能力,阻碍患者下肢功能的恢复。
临床上多采用下肢跖屈肌牵拉、诱发足背屈运动训练以及功能性电刺激(functional electrical stimulation,FES)等常规康复训练。但常规治疗仅在有限的治疗时间段内疗效明显,治疗效果难以保障。另一方面,若无法在患者下肢跖屈肌出现高张力的时候有效控制踝关节角度,则易出现踝关节挛缩等畸形。踝关节畸形状态的出现将严重影响患者患肢承重能力、平衡能力,使患者不具备站立和步行的基本条件而无法完成站立和步行训练,更难以实现功能恢复。
可调踝足矫形器在常规踝足矫形器的基础上增加了双侧可调型拉带。可调型拉带设计一方面可以满足踝关节不同跖屈内翻状态,另一方面可依据患者不同康复进展做出相应的调整,以适应动态变化的康复过程。因此可调踝足矫形器联合康复训练应用于改善颅脑损伤患者踝关节功能有一定科学性和探讨空间。与王金宇等[10]研究的自主研发可调式多功能踝足矫形器可有效改善脑损伤患者踝关节控制能力的结论一致。
任武[11]认为可调式矫形器在双侧踝关节部位设有的调节装置,可调节踝关节于不同的跖屈、背伸位及内翻外翻,可根据临床康复需要及时调整患者使用角度,避免长期卧床造成的踝关节周围肌肉的萎缩以及肌紧张等症状,康复训练后可调踝足矫形器的介入不仅可以维持和巩固康复训练的效果,也可为中枢神经系统输入本体感觉冲动[12]。可调踝足矫形器联合康复训练不仅改善下肢痉挛与肌肉萎缩状态,加强运动神经传导,促进恢复大脑中的运动神经功能。同时,还可加强下肢双侧肌肉群平衡,提升肌力,从而预防足下垂的发生[13],为患者下一阶段的站立和步行等运动功能的恢复创造必要条件。可调踝足矫形器联合康复训练的治疗模式可以为现代康复治疗提供新思路、新方法,同时对提高患者生存质量,缩短住院日,降低医疗费用,减轻社会、家庭和个人的经济负担大有意义[14-15]
本研究的局限性在于样本量偏小,不足以代表所有颅脑损伤患者;且本研究未对转科、出院患者继续追踪。可调踝足矫形器联合功能训练对患者步行能力的影响还不了解。今后需扩大样本量、拓宽观察面,开展多中心随机对照研究,基于循证医学方法探索颅脑损伤患者踝关节异常的预防方案。

We aim to demonstrate that multidisciplinary treatment through neurosurgical intervention, pharmacotherapy, rehabilitation, speech, and psychological therapy is the most promising treatment approach for patients with severe craniocerebral injuries. Here we describe two clinical cases who presented with an unexpectedly positive outcome as both patients regained mobility and the ability to function independently after receiving multimodal therapy.

The aim of this study was to describe systematically the best available intervention evidence for children with cerebral palsy (CP).This study was a systematic review of systematic reviews. The following databases were searched: CINAHL, Cochrane Library, DARE, EMBASE, Google Scholar MEDLINE, OTSeeker, PEDro, PsycBITE, PsycINFO, and speechBITE. Two independent reviewers determined whether studies met the inclusion criteria. These were that (1) the study was a systematic review or the next best available; (2) it was a medical/allied health intervention; and (3) that more than 25% of participants were children with CP. Interventions were coded using the Oxford Levels of Evidence; GRADE; Evidence Alert Traffic Light; and the International Classification of Function, Disability and Health.Overall, 166 articles met the inclusion criteria (74% systematic reviews) across 64 discrete interventions seeking 131 outcomes. Of the outcomes assessed, 16% (21 out of 131) were graded 'do it' (green go); 58% (76 out of 131) 'probably do it' (yellow measure); 20% (26 out of 131) 'probably do not do it' (yellow measure); and 6% (8 out of 131) 'do not do it' (red stop). Green interventions included anticonvulsants, bimanual training, botulinum toxin, bisphosphonates, casting, constraint-induced movement therapy, context-focused therapy, diazepam, fitness training, goal-directed training, hip surveillance, home programmes, occupational therapy after botulinum toxin, pressure care, and selective dorsal rhizotomy. Most (70%) evidence for intervention was lower level (yellow) while 6% was ineffective (red).Evidence supports 15 green light interventions. All yellow light interventions should be accompanied by a sensitive outcome measure to monitor progress and red light interventions should be discontinued since alternatives exist.© 2013 Mac Keith Press.
