Limb Rehabilitation

Recently, robotic-assisted stroke rehabilitation became an important research topic due to its capability to provide complex solutions to perform the customized rehabilitation motion with enhanced resources than the traditional rehabilitation. Involving robotic devices in the rehabilitation process would increase the number of possible rehabilitated patients, but placing the patient inside the workspace of the robot causes a series of risks that needs to be identified, analyzed and avoided. The goal of this work is to provide a reliable solution for an upper limb rehabilitation robotic structure designed as a result of a risk assessment process. The proposed approach implies a hazard identification process in terms of severity and probability, a failure mode and effects analysis to identify the possible malfunctions in the system and an AHP (Analytic Hierarchy Process) to prioritize the technical characteristics of the robotic structure. The results of the risk assessment process and of the AHP provide the base of the final design of the robotic structure, while another solution, in terms of minimizing the risk for the patient injury, is obtained using an external measuring system.

Adverse Health

Virtually all chemical substances may cause adverse health effects, depending on the dose and conditions under which individuals are exposed to them. Toxicology - the study of harmful effects of chemicals on living organisms - provides the scientific data base on which risk assessment of adverse health effects stands. Risk assessment (RA) is the process of estimating the probability that a chemical compound will produce adverse effects on a given population, under particular conditions of exposure. Risk assessment process consists of four stages: Hazard Identification (HI), Exposure Assessment (EA), Dose-Response Assessment (DRA), and Risk Characterization (RC). The risk assessment process as a whole makes it possible to carry out cost(risk)/benefit analysis, and thus risk management, on a rational basis. A capacity to undertake risk assessment is thus sine qua non for making decisions that are concerned with achieving a balance between economic development and adequate protection of public health and the environment.

Risk Assessment Process

In the medical device industry, risk assessment is required for product development and support, regulatory compliance, and manufacturing support. The risk assessment process can be divided into four major steps. The first step, hazard identification, involves determining whether exposure to an agent can cause an increased incidence of an adverse health condition (e.g., acute toxicity, cancer, birth defects, etc.). The next step in the risk assessment process is to characterize the dose-response relationship. Virtually all chemicals are toxic at some dose, and toxicity is dependent upon the circumstances of exposure, including the amount of substance available, the nature of contact with the substance, and the duration of contact. For both hazard identification and dose-response assessment, the use of scientifically valid data from any source, including data from published literature, is a central feature. Exposure assessment is the determination or estimation of the frequency and duration of human exposure to an agent. The last step in the risk assessment process is risk characterization. Risk characterization uses information from all three previous steps to estimate the probability of an adverse effect under the various conditions of described human exposure. All the components of risk assessment provide the framework for a working paradigm used in evaluating the safety of new or modified medical devices.
