tone is functionally as resistance to passive movement. it is separated into postural tone and phasic tone. phasic tone is the result of rapid stretching of a tendon and the muscle spindle, however postural tone is the result of a steady, restrained strech on muscles. hypottonia is a decreased resistance to passive movement. the term floppy is frequently used to describe hypotonic children. in ...

Familial episodic ataxia of lambs is a congenital transient autosomal dominant disorder of newborn lambs, with varying expressivity. Affected lambs show episodes of an asymmetric ataxic gait, base-wide extensor hypertonia of the thoracic limbs and flexor hypertonia of the pelvic limbs. The aim of the study was to determine the genetic variant causing familial episodic ataxia in lambs. Using who...

BACKGROUND In India, tuberculous meningitis (TBM) is still a major cause of neurological disabilities and death. AIM To identify the clinical variables which predict the outcome in childhood TBM. SETTING Tertiary teaching hospital. DESIGN Prospective observational study. MATERIALS AND METHODS Thirty-six clinical variables were analyzed in 123 consecutive children with TBM admitted betwe...

A regional technique for the study of curare sensitivity has been applied to patients with Duchenne type muscular dystrophy, myotonic disorders, certain lower motor neurone disorders, to patients with weakness in the arm after hemiplegia, to patients with hyper-reflexia and hypertonia without weakness, and to Parkinsonism. In the dystrophy patients, sensitivity to curare differs from normal con...

The aim of this study was to assess the efficacy of fissurectomy with skin advancement flap in healing chronic anal fissures without hypertonia of the internal anal sphincter. Twenty-six consecutive patients who failed healing after well-practiced topical medical therapy were enrolled. Anorectal manometry was performed preoperative and 6 months postoperatively. All patients were treated with fi...

Patients with an upper motor neurone syndrome (CP) suffer from many disabling primary symptoms: spasms, weakness, and loss of dexterity. These primary 'neurogenic' symptoms often lead to secondary disabilities, muscle contractures, and tertiary effects, bone deformations. A common symptom of CP is hypertonia, with the consequence that the involved muscles remain in an excessively shortened leng...

In a clinical setting, where motor-driven systems are not readily available, the major difficulty in the assessment of the stretch reflex lies in the control of passive limb displacement velocity. A potential approach to this problem arises from the use of manual sinusoidal movements (made by continuous alternating flexions and extensions) paced by an external stimulus. Unfortunately, there are...

Disorders of the maternal-placental-fetal unit often results in fetal brain injury, which in turn results in one of the highest burdens of disease, because of the lifelong consequences and cost to society. Investigating hypoxia-ischemia in the perinatal period requires the factoring of timing of the insult, determination of end-points, taking into account the innate development, plasticity, and...

BACKGROUND Extracorporeal shock wave therapy has been reported to be effective in reducing muscle hypertonia in adults. AIM To evaluate the effect of shock wave treatment of spastic muscles in children with cerebral palsy. METHODS Twelve children with spastic equinus foot (6 boys,6 girls; mean age 8 years (standard deviation (SD) 2.31)) were monitored. Clinical (Ashworth Scale, passive rang...
