dyssynergia

 [dis″sin-er´jah]
muscular incoordination.
dyssynergia cerebella´ris myoclo´nica dyssynergia cerebellaris progressiva associated with myoclonus epilepsy.
dyssynergia cerebella´ris progressi´va a condition marked by generalized intention tremors associated with disturbance of muscle tone and of muscular coordination; due to disorder of cerebellar function.
detrusor-sphincter dyssynergia contraction of the urethral sphincter muscle at the same time the detrusor muscle of the bladder is contracting, resulting in obstruction of normal urinary outflow; it may accompany detrusor hyperreflexia or instability.

dys·syn·er·gi·a

(dis'in-ĕr'jē-ă),
An aspect of ataxia, in which an act is not performed smoothly or accurately because of lack of harmonious association of its various components; usually used to describe abnormalities of movement caused by cerebellar disorders.
[dys- + G. syn, with, + ergon, work]

dys·syn·er·gi·a

, dyssynergy (dis'sin-ĕr'jē-ă, -synĕr-jē)
An aspect of ataxia, in which an act is not performed smoothly or accurately because of lack of harmonious association of its various components; usually used to describe abnormalities of movement caused by cerebellar disorders.
[dys- + G. syn, with, + ergon, work]

dyssynergia

Puppet-like movement resulting from the inability to coordinate simultaneous movement at the various joints in a limb. Movement is broken up into its separate components. This is a sign of disorder of the CEREBELLUM.

Patient discussion about dyssynergia

Q. Can I inherit ataxia to my children? I have Ataxia. Does this mean that all my kids will have it too?

A. The hereditary ataxias are genetic, which means they are caused by a defect in a certain gene that is present from the start of a person's life. There are both dominant and recessive ataxias. If it's a dominant ataxia then each child of a parent with an autosomal dominant ataxia gene has a 50/50 chance of whether they will inherit the ataxia gene or not. If it's recessive then it takes a "double dose" of the ataxia gene to result in disease symptoms. Both parents must be carriers of the disease gene in order for it to pass on. Each child of parents who are both carriers of a recessive disease has a 25% chance of inheriting two ataxia genes so will develop the disease, a 50% chance of inheriting just one of the ataxia genes and, therefore, be a carrier and a 25% chance of inheriting no ataxia gene and be completely free of ataxia.
Therefore, it depends which ataxia gene you have, if it's dominant or recessive and whether your spouse is a carrier too.

There can be any abnormality in sphincter function although sphincter deficiency or detrusor sphincter dyssynergia have been reported (5, 8).
Electromyography Used to determine (EMG) coordination between the detrusor function and the pelvic floor during bladder filling and during the voiding phase when detrusor sphincter dyssynergia or neurological involvement are suspected with regards to LUTs or to evaluate the integrity of the pelvic floor.
This finding is not unexpected because hard stool is a common feature of DD [1] and because BFT is known to improve dyssynergia and allow more efficient stool evacuation.
(14) showed that pinprick sensation and presence of BCR might be predictive of volitional voiding, but they were not sensitive about predicting detrusor hyperreflexia and sphincter dyssynergia. According to Wyndaele (15), presence of BCR and anal reflex were significantly associated with DO and sphincter dyssynergia and absence of BCR was significantly associated with detrusor acontractility.
In patients with a neuropathic bladder, disordered innervation commonly results in dyssynergia between the detrusor and external sphincters, which adversely affects bladder function.

Since Preston and Lennard-Jones (1985) reported this paradoxical response pattern, several investigators have described this functional defecation disorder using a variety of terms, such as anismus (Miller et al., 1991; Preston & Lennard-Jones, 1985), spastic pelvic floor syndrome (Kuijpers & Bleijenberg, 1985), paradoxical puborectalis contraction (Jones, Lubowski, Swash, Path, & Henry, 1987), pelvic floor dyssynergia (Pucciani et al., 1998) and, in the current Rome III diagnostic criteria for functional gastrointestinal disorders, dyssynergic defecation (Bharucha, Wald, Enck, & Rao, 2006).
