There is difficulty in maintaining balance, the posture is stopped and the attitude is flexed. Clinical features of Parkinsonism General: Masked face Stuped postureflexed attitude Slurred indistinct speech Bradykinesia Difficultyslowness in initiating voluntary movements Gait postures Difficulty in maintaining balance Rapid short steps, tendency to run festinant gait Difficulty in stopping suddenly Reduced swinging of arms Tremors: Resting 4-6 hzs Diminish with movement and attention Fingers most commonly affected Postural 8-10 hzs Persist on movement Rigidity Lead pipe more in lower limbs and trunk Cog wheel more in upper limb Others Normal deep tendon reflexes Flexor plantar response negative Babiniski Normal intelligence Small handwriting Emotional lability Clinical Features of Parkinsons Disease: A diagnosis of PD can be made with some confidence in patients who present with at least two of the three cardinal signs - rest tremor, rigidity, and bradykinesia. Tremor is particularly important, as it is present in 85 of patients with true PD; Masked facies, decreased eye blinking, stooped posture decreased arm swing complete the early picture. Vague feeling of weakness and fatigue, incoordination aching, and discomfort may also herald the onset. Rest tremor, at a frequency of 4 to 6 Hz, typically and wrist where it may have a pill-rolling character. Abnormalities of balance and posture tend to increase in prominence as the disease progresses. Flexion of the head, stooping, and posture while walking are common, as are changes in the posture of the fingers and hands. Postural instability is one of the most disabling to major morbidity and mortality.
