In general, adequate movement of the ankle joint is known to play an important role in functional activities. Stroke survivors frequently have limited range of motion of the ankle, leading to dysfunctional weight transfer toward the paretic lower limb during standing or gait. The purpose of this study was to investigate the effects of talocrural mobilization with movement (MWM) on ankle strength, dorsiflexion passive range of motion (DF-PROM), and weight-bearing ability on the paretic limb during standing or gait in stroke patients with limited ankle dorsiflexion.
Twenty-six participants with chronic hemiplegia (>6 months post stroke) were divided into 2 groups: MWM group (n = 13) and control group (n = 13). Both groups attended conventional physiotherapy sessions 3 times a week for 5 weeks. Additionally, the MWM group underwent talocrural MWM 3 times a week for 5 weeks. Isokinetic ankle strength, DF-PROM, and weight-bearing ability measures included the limit of stability (LOS); gait parameters were evaluated before and after interventions.
Plantarflexors peak torque and DF-PROM significantly increased in the MWM group. In addition, forward and forward-paretic direction LOS significantly increased in the MWM group. Paretic direction LOS, single-limb support phase of the paretic limb significantly increased and double limb support phase significantly decreased within the MWM group.
This study demonstrates that talocrural MWM has an augmented effect on ankle strength, mobility, and weight-bearing ability in chronic stroke patients with limited ankle motion when added to conventional therapy.
一般而言,踝关节的充分活动在功能活动中起着重要作用。中风幸存者的踝关节活动范围常常受限,导致站立或步态期间向患侧下肢的功能失调性体重转移。本研究的目的是调查在踝关节背屈受限的中风患者中,踝关节活动时松动术(MWM)对踝关节力量、背屈被动活动范围(DF-PROM)以及患侧肢体在站立或步态时的负重能力的影响。
26名慢性偏瘫患者(中风后>6个月)被分为两组:MWM组(n = 13)和对照组(n = 13)。两组均每周参加3次常规物理治疗课程,共5周。此外,MWM组每周接受3次踝关节MWM,共5周。等速踝关节力量、DF-PROM和负重能力测量包括稳定极限(LOS);在干预前后评估步态参数。
MWM组中跖屈肌峰值扭矩和DF-PROM显著增加。此外,MWM组向前和向前患侧方向的LOS显著增加。MWM组内患侧方向LOS、患侧肢体的单肢支撑期显著增加,双肢支撑期显著减少。
本研究表明,对于踝关节活动受限的慢性中风患者,在常规治疗基础上增加踝关节MWM对踝关节力量、活动度和负重能力有增强作用。
