“…In clinical settings, for example, vibration therapy applied on plantar fascia has been used to improve spasticity of lower limbs ( Usuki and Tohyama, 2011 ). In our study, vibration locally applied to plantar hind paw region inhibited the increase of collagen I in crural fascia induced by HU.…”

The deep fascia of the vertebrate body comprises a biomechanically unique connective cell and tissue layer with integrative functions to support global and regional strain, tension, and even muscle force during motion and performance control. However, limited information is available on deep fascia in relation to bone in disuse. We used rat hindlimb unloading as a model of disuse (21 days of hindlimb unloading) to study biomechanical property as well as cell and tissue changes to deep fascia and bone unloading. Rats were randomly divided into three groups (n = 8, each): hindlimb unloading (HU), HU + vibration (HUV), and cage-control (CON). The HUV group received local vibration applied to the plantar of both hind paws. Micro-computed tomography analyzed decreased bone mineral density (BMD) of vertebra, tibia, and femur in HU vs. CON. Biomechanical parameters (elastic modulus, max stress, yield stress) of spinal and crural fascia in HU were always increased vs. CON. Vibration in HUV only counteracted HU-induced tibia bone loss and crural fascia mechanical changes but failed to show comparable changes in the vertebra and spinal fascia on lumbar back. Tissue and cell morphometry (size and cell nuclear density), immunomarker intensity levels of anti-collagen-I and III, probed on fascia cryosections well correlated with biomechanical changes suggesting crural fascia a prime target for plantar vibration mechano-stimulation in the HU rat. We conclude that the regular biomechanical characteristics as well as tissue and cell properties in crural fascia and quality of tibia bone (BMD) were preserved by local plantar vibration in disuse suggesting common mechanisms in fascia and bone adaptation to local mechanovibration stimulation following hind limb unloading in the HUV rat.

“… 10 Here we applied vibratory stimulation to the plantar fascia because our previous FMD study demonstrated that the application of vibratory stimulation to the plantar fascia was more effective than that to the spastic muscle directly. 5 The mechanoreceptor reactive to vibration stimuli with a frequency >80 Hz has been known to be the Pacinian corpuscles. The Pacinian corpuscles, which are widely distributed in the mammalian body, were found in the dermis and subcutaneous tissues of the fingers, palm, and sole in addition to the muscles and tendons.…”

“… 4 Recently, we have reported that vibratory stimulation of the plantar fascia using a hand-held vibration massager attenuated severe planter pain and lower-limb spasticity in 1 patient with FMD. 5 The spherical-shaped head of the frequency generator used in that study fitted the plantar curvature. The method was inexpensive, noninvasive, simple, and convenient.…”

Fetal-type Minamata disease is caused by the exposure to high concentrations of methylmercury in the fetal period and shows cerebral palsy-like clinical features. Relief of spasticity is a major task of rehabilitation to improve their activities of daily living.Here we report the effect of long-term vibration therapy on bilateral lower-limb spasticity in 3 patients with fetal-type Minamata disease. We used a simple, inexpensive, and noninvasive approach with hand-held vibration massagers, which were applied to the plantar fascia at 90 Hz for 15 minutes.The effect was observed soon after the first treatment and resulted in better performance of the repetitive facilitation. Vibration therapy for 1 year improved Modified Ashworth Scale for the ankle flexors in 2 cases. The labored gait improved and gait speed increased in another case. Continued vibration therapy for another 1 year further improved Modified Ashworth Scale score and range of motion of ankle dorsiflexion in 1 case. This case showed the decreased amplitude of soleus H-reflex after the 15-minute vibration therapy, suggesting that α-motor neuron excitability was suppressed.Vibration therapy using a hand-held vibration massager may offer safe and effective treatment for lower-limb spasticity in patients with chronic neurological disorders.

“…However, guidelines still need to be worked out for selection of the motor training task(s). Recently, the use of vibratory stimulation applied to the whole body [77] or the plantar fascia [78] has also shown promise. Further research is however needed on how various physical modalities and forms of exercise modify and re-balance the tensional and compressive forces to relieve contractures and spasticity.…”

Histolopathological studies have demonstrated a generalized increase in extracellular connective tissue in spastic muscles. It is known that increased connective tissue in an immobilized and contracted muscle reduces its compliance and could reduce the threshold for stimulation of spindle receptors in the muscle. Various authors have investigated how increased stretch-induced stimulation of spindles in muscles with stiffer connective tissue can contribute to spasticity. In this review, we compile evidence for the idea that the primary injury to the central nervous system that leads to muscle paresis also triggers changes in the viscosity of the extracellular matrix due to abnormal turnover of hyaluronic acid. Hyaluronic acid is a complex molecule that exhibits non-Newtonian behavior at higher concentrations, leading to altered connective tissue viscosity, which begins a vicious circle that exacerbates spasticity through reduced tissue compliance and potentiation of reflex mechanisms and fibrosis, and contributes to abnormal limb posturing, pain symptoms, and decreases in activities of daily living. The rationale for emerging treatments to break this vicious circle are discussed.
