RESUMO
The patient was a 38-year-old male referred to physical therapy with complaints of right lower extremity radicular pain and left lower extremity weakness. Following physical therapy examination, the primary care physician referred the patient to a neurologist, who performed electromyography and nerve conduction studies and ordered a magnetic resonance image. Cervical spine imaging revealed a C5-6 disc extrusion with myelopathy. J Orthop Sports Phys Ther 2017;47(7):510. doi:10.2519/jospt.2017.5071.

Hand held dynamometry (HHD) is a more objective way to quantify muscle force production (MP) compared to traditional manual muscle testing. HHD reliability can be negatively impacted by both the strength of the tester and the subject particularly in the lower extremities due to larger muscle groups. The primary aim of this investigation was to assess intrarater reliability of HHD with use of a portable stabilization device for lower extremity MP in an athletic population. Isometric lower extremity strength was measured for bilateral lower extremities including hip abductors, external rotators, adductors, knee extensors, and ankle plantar flexors was measured in a sample of healthy recreational runners (8 male, 7 females, = 30 limbs) training for a marathon. These measurements were assessed using an intrasession intrarater reliability design. Intraclass correlation coefficients (ICC) were calculated using 3,1 model based on the single rater design. The standard error of measurement (SEM) for each muscle group was also calculated. ICC were excellent ranging from ICC (3,1) = 0.93-0.98 with standard error of measurements ranging from 0.58 to 17.2 N. This study establishes the use of a HHD with a portable stabilization device as demonstrating good reliability within testers for measuring lower extremity muscle performance in an active healthy population.
