- Hemiplagia (Pakshvadh):
When vaayu involves one-half of the body afflicting the vessels and the nerves, it produces hemiplagia and loosens the ligamentous supports of the joints. There is motor as well as sensory loss of the patient’s whole body or of a half of it. It is called ekaang rog and its other name is pakshavadh. Similarly, if the whole body is involved by vaat, it is known as sarvaangrog.
Predominance of the doshas in the paralytic cases: If pitta is associated with vaat in case of paralysis, it gives rise to a burning sensation, fever and fainting in addition to the other usual clinical features of paralysis; whereas if kapha is associated with the same, it gives rise to subnormal temperature, oedema and a feeling of heaviness.
Prognosis: When a part of the body is paralyzed due to vitiation of vaat alone, the condition is difficult to cure but if it is associated with other doshas i.e. pitta or kapha, it is curable; whereas if it is due to degenerative changes, it becomes incurable.
Further signs of incurability: Paralysis occurring in the pregnant, during puerperium in a child, an old person and in an emaciated one or of haemorrhagic origin, or else if there is unconscious should be discarded from treatment as incurable.
- Facial Paralysis (Ardita):
Aetiopathogenesis: While a person is shouting persistently at high pitch of his voice, eating hard articles in his diet, laughing or yawning, or else while he is carrying heavy load on his head, is lying on an uneven ground, vaayu in relation to the head, nose, lips, chin, forehead and the eyes afflicts the face and produces facial paralysis.
Clinical Features: One half of the face becomes twisted and the neck also rotates; the head keeps on shaking, the speech gets blurred and there is asymmetry of the eyes, the eyebrows and the cheeks etc. At the same time, there is ipsilateral pain in the neck, the chin and the teeth.
Prodromal Features: Its prodromal features are horripilation, tremors, congestion in the eyes, belching, numbness and pins and needles in the skin along with the stiffness of the neck and the jaw. Prognosis: Facial Paralysis in the emaciated, in the one having fixed eyes and in one whose speech is continuously inarticulate, is not curable, as also when it is advanced, is of three years duration or when it is associated with tremors.
- Hanugraha (Dislocation of Jaw):
While scraping the tongue or eating dry food and due to trauma, vaayu which is situated at the temporo-mandibular joint of the jaw, becomes vitiated and dislocates the mandible making the mouth either remain open or closed. The condition is called hanugraha. It causes inability to masticate and speak.
- Manyastambha (Torticollis):
Day sleep or sleeping on an uneven bed and gazing upwards for long periods produce manyastambha. Here, vaayu is enveloped by kapha.
- Jihvastambha (Paralysis of the tongue):
Vaayu located in the speech carrying channels causes immobility of the tongue. This is known as jihvastambha. This leads to a difficulty in swallowing of food and drinks and in speaking.
Vaayu vitiating the rakta afflicts the vessels going towards the head and produces their roughness, along with pain and blackish discoloration; this condition is called siragraha and is incurable.
