TRADITIONAL RISK FACTORS DEFINITION:
A risk factor is any attribute, experience, or exposure that increases the probability of the occurrence of a disease or disorder, although it is not necessarily a causal factor.

Risk Factor 2: Awkward Positions/Posture, Awkward postures overload muscles and tendons. This increases the compression on joints, nerves and circulation and put a prolonged static strain on the tissues. Ideal positions for some joints are as follows: Low back flexion < 20º, lateral flexion < 30º, Neck extension 0, flexion < 20º, lateral flexion < 30º, rotation < 30º, Shoulder flexion < 45º, Abduction < 90º, Wrist < 45º flexion or extension. For more specifics on correct postures and positions use the contact page and we will send the requested information.

TRADITIONAL ERGONOMIC RISK FACTOR 1:
CONTACT STRESS: Frequent or continuous use of tools or constant pressure from leaning on sharp edges or hard surfaces. This compresses tissue decreasing blood flow and slowing nerve conduction. This can be controlled by proper tool selection (pounding with a hammer not the heel of the hand), utilizing power tools with a clutch to decrease torque, round the edges of tables or work benches allow short breaks to decrease prolonged contact.

BACK INJURIES IN THE WORKPLACE: Lower back injuries are among the most common complaints seen in workers’ compensation. Approximately 85% of the general population has an episode of back pain in their lifetime. The peak incidence of lower back pain is found in the most productive years of life 25-60, making work related back injuries a major health concern. In order to address this concern, a strategic plan to reduce work related back injuries is required. The following steps should be taken: (1) identification of ergonomic risk factors(2) implementing ergonomic control measures, (3) follow safe work practices including utilizing proper posture and safe lifting techniques during work.

HIGH TASK REPETITION: A job is classified as highly repetitive if the cycle time is less than 30 seconds, or if a task or motion is performed more than 50% of the time it takes to complete the work cycle. Work and rest cycles are the intervals of time measured during one work cycle. The more repetitive the task, the less recovery time there is for the muscles and tendons. This increases the risk for cumulative trauma disorder (CTD).

Work related musculoskeletal disorders (WMSDs) of the upper extremity are now the leading cause of lost workday injuries and a significant burden to industry. These work related upper extremity injuries account for $1 of every $3 spent for Worker’s Compensation. Direct costs include medical treatment and indemnity. Companies can prevent most work-related injuries by identifying risk factors and implementing prevention strategies. These risk-reduction programs can protect company profits and their employees.
