Neurogenic Voice Problem
|
- Either PNS or CNS problems
If CNS affects causes: - intiation and coordination problems Id PNS affected causes: - Instruction of CSN to muscles and various organs |
|
|
Peripheral Nerve Lesion
|
Intrinsic muscles hat are involved predict dysfunction
- Most common unilateral |
|
|
Cerebellum
|
Responsible for controlling voice atributes such as pitch and loudness- NOT initiation of phonation or speech
|
|
|
Extrapyramidal System Disease
|
Extrapyramidal system Functions to coordinate phonation
-Diseases affects basal ganglia causing parkinsons Symptoms: - monopitch - rigidity - tremor - reduces ROM - dysarthria (prosodic excess, monopitch, harshness) |
|
|
Lower motor neuron damage
|
Affects brainstem and medulla
|
|
|
Upper motor neuron diseases
|
Damage to pramidal pathways causes:
-spasticity - weakness - slows movement and limits range Symptoms: - harshness and hoarseness Etiology: - strokes, MS, cerebral palsy UMN diseases: Shy Drager, ALS, Huningtons Chorea |
|
|
Muliple Sclerosis
|
- Disease affecing myelin
and CNS Etiology: - multiple scarring of white matter of brainstem Symptoms: - 1/2 have normal speech production - reduction of vocal loudness - misarticulation - hypernasal/ breathy |
