Vibration stimulates specific receptors, cutaneous and musculo-tendinous. The aff erent impulses travel through spinal neurons to thalamus and cortical structures. The local muscular response to a vibration is a tonic vibratory refl ex. This refl ex depends on many factors: frequency, amplitude, and tendon and muscle length. Based upon this refl ex, vibration produced alteration of isometric and isotonic contraction, fl exibility, spasticity. Many studies investigated facilitator eff ects on movement in stroke patients and spinal cord injuries. There is further need to set the place of vibration in the therapeutic fi eld of motor control enhancement.
振动刺激特定的感受器,包括皮肤感受器和肌肉肌腱感受器。传入冲动通过脊髓神经元传导至丘脑和皮质结构。肌肉对振动的局部反应是一种紧张性振动反射。这种反射取决于许多因素:频率、振幅以及肌腱和肌肉长度。基于这种反射,振动会引起等长收缩和等张收缩、柔韧性、痉挛的改变。许多研究调查了振动对中风患者和脊髓损伤患者运动的促进作用。在增强运动控制的治疗领域中,进一步确定振动的作用仍有必要。
