Welcome to ERS

ERS assesses the impact of an injury on a person’s ability to perform meaningful activities. ERS provides Functional Capacity Evaluations that clearly document your client’s abilities and limitations to perform personal care, homemaking, work, family and recreation activities, and work. These findings are used to bridge the gap between medical evidence and vocational findings related to employability; to set the foundation for an economic evaluation related to lost wages or loss of household services, which enable the attorney to determine realistic case values.

Functional Capacity Evaluations are provided to assess and document injured and/or disabled persons’ current functional capacities and limitations, and the impact on the person’s vocational status and overall quality of life.

Hand/Upper Extremity Functional Evaluations focus on how a person’s hand, wrist, elbow or shoulder injury affects their daily function for home, recreational and work activities.

In conjunction with the Functional Capacity Evaluation findings, the vocational analysis can determine if a person is able to return to his/her past or alternate work, with or without accommodations, or he/she is precluded from employment.

We assess a person’s Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) capacities and/or limitations to appreciate how his/her injury impacts the performance of personal care, homemaking, home maintenance, driving, recreation and leisure activities.

ERS provides case file reviews to assess if a treating therapist’s provided care was up to accepted standards or deviated from this level.

ERS provides workplace evaluations to assess for injury risk factors that can affect worker health and performance, and Physical Job Demand analyses to assess for whether there is a job match between injured workers’ abilities and those required for safe job performance.
