Therefore, in the present study line drawing in eight different directions was included in addition to circle and spiral tracing tasks.
To summarize, the present study aimed to provide quantitative measures to evaluate bradykinesia, micrographia and tremor in one assessment by recording pen tip movement during handwriting tasks, including tracing geometric figures and actual writing. Introduction Parkinson's disease PD is a neurodegenerative disorder which generally results in several motor symptoms.

Kicking, thrashing, flailing your arms, and even falling out of bed can be indications of a serious problem. The lack of dopamine is thought to result in the symptoms that affect the way you move. While healthy persons needed a single EMG burst to execute arm movements, patients with PD required multiple bursts, a pattern which was aggravated during large-amplitude movements [ 19 — 22 ]. The shaking will worsen and become noticeable to others, however, as the condition progresses. The untrained sequence involved a continuous figure 8-like movement [ 14 ]. The tremor is usually most noticeable at rest. Also, patients with PD modulated acceleration measures inefficiently as compared with controls, i. In a study of Ponsen et al. Additionally, rest tremor was investigated. Exclusion criteria were: i color blindness or other impairments in vision interfering with handwriting; ii upper limb problems unrelated to PD; and iii deep brain stimulation. However, rating scales highly depend on the experience and interpretation of the physician performing the assessment and have limited precision for quantifying upper limb motor skill. A rest task was added as well, based on the task used by Scanlon et al. Therefore, only results from the large-amplitude condition are described in detail. Treatment with dopaminergic medication or deep brain stimulation was found to have a beneficial effect on the latter three variables, but not on amplitude [ 10 — 13 ].
Participants Ten patients with PD mean age In healthy persons, amplitude and speed during voluntary arm and hand movements, such as writing, obey certain generally accepted rules of motor control: irrespective of the muscles involved, larger movement amplitudes are accompanied by an increase in velocity [ 15 ].
It may be time to see a doctor if you are noticing symptoms that keep appearing. Similarly, the difference between baseline and post-training and between baseline and retention for the writing parameters were correlated to the clinical characteristics for the EXP and PLB group separately.
Exclusion criteria were: i color blindness or other impairments in vision interfering with handwriting; ii upper limb problems unrelated to PD; and iii deep brain stimulation.
