Reproducibility of kinematics indexes of upper arm reaching movement in robot assisted therapy

Over the last decades, numerous and extensive research programs have been conducted in the field of robotic and proprioceptive rehabilitation. Robotic rehabilitation allows to record quantitative data about movement patterns that can help clinicians to better address the rehabilitation protocols providing information not captured using clinical measures, but the biome-chanical parameters proposed until today, to evaluate the quality of the movement are not yet standardized. Equally, the proprioception rehabilitation is known to play important roles in the planning and control of limb posture and movement. The Russian Academy of Sciences has recently developed the "Regent Suit" (RS), an experimental medical device derived from a suit worn by astronauts for therapeutical purposes after space flights. Although preliminary studies describe rehabilitation outcome of the RS in stroke, EMG changes induced by the suit are not known. The purpose of this paper is to review the rehabilitation activities employed at Salvatore Maugeri Foundation in the last two years, showing the main robotic and proprioceptive rehabilitation protocol developed to carefully analyse the motor strategies of the movement and of the gait in pathological conditions

Arm reaching movements (ARM) are mainly used in rehabilitative settings, as robot mediated therapies, virtual reality and motion capture systems in exergaming. ARM typical consist of gaussian-like bell shaped velocity profile. No previous paper addressed in details their relationships with amplitude and speed of the movement and aim of the paper is to study existing correlations between quantitative kinematics indexes (KI) and to describe their relationships with the amplitude and the velocity of the movement in normal subjects. We studied about one thousands of horizontal and vertical ARM of 10 normal subjects at four amplitude's values (15-20-25-30°) and at three different target velocity (20-30-40°/s), quantitatively evaluated by symmetry, skewness, kurtosis and smoothness indexes. KI showed extremely low correlations to each other, clearly describing different ARM features, higher correlations with the velocity than with the amplitude of the movement, and in vertical antigravitary rather than horizontal ARM. Among all KI, smoothness showed the higher correlations' values, following an exponential growth relationship both with velocity and amplitude in horizontal and vertical ARM
