For assessment of gait disorders, speed and stride are measured during 10 m-walking test. However, changes in these two parameters are nonspecific since they are observed in various gait disorders. In addition, the 10-m walking is short and reflects only one aspect of daily living and the results could be affected by emotional stress. Quantitative analysis of the gait acceleration cycle and amplitude has allowed characterization of the brady kinematic features of gait disorders in patients with Parkinsonâs disease. Gait disorders are cardinal neurological symptoms; locomotor disability negatively affects quality of daily life. The features of gait disorders can be clinically distinguished in various neurological diseases. For example, patients with Parkinsonâs disease (PD) walk with forward posture, small steps and slow cycle, frequently accompanied by freezing of gait and festination. First, the majority of previous studies have documented a decrease in velocity and stride during walking. However, walking with short stride, wide stance, slow speed, and prolonged double support period is the final common expression of any dysfunction of the gait control system, not the characteristic change .Thus, in addition to these nonspecific and secondary changes. A new device (portable gait rhythmogram, PGR) as developed for long-term monitoring of the gait cycle and/or force during walking in routine daily activity.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
