Background The assessment and treatment of writer’s cramp is complicated due to the variations in the forces and angles of involved joints. Additionally, in some cases compensatory movements for cramp relief further complicates assessment. Currently these variables are subjectively measured with clinical scales and visual assessments. This subjectivity makes it difficult to successfully administer...
In this paper, a novel tool is suggested which allows to simultaneously record arm joint angles and the applied forces of patients with writer's cramp during the performance of multiple writing and drawing tasks. The presented tool identifies the role of the upper limb joints and exerted forces once a cramping event happens. Over the past decade different kinematic analyses have been introduced in...
In this study, kinematic characteristics of writing are compared in 5 patients with writer's cramp who performed a set of standardized writing tasks. The kinematic characteristics include upper limb joint angles, vertical hand pressure, and finger grip force. The effect of writing on different inclined supporting surfaces is also investigated. Our results indicate that altering upper limb posture...
