Subjective strength assessments or unstructured free-weight testing often introduce significant inter-tester variability and injury risks. Developed originally by Dr. Andrew Jackson at the University of Houston, the Jackson Strength Evaluation System directly addresses these diagnostic challenges by providing a precise, electronic load-cell-based testing platform designed specifically to measure static isometric strength across major muscle groups, meeting recognized National Institute of Occupational Safety and Health (NIOSH) lifting protocols.\u003c\/p\u003e\n\u003cp\u003eDesigned explicitly for physical therapists, occupational health physicians, industrial evaluators, and ergonomic specialists, the system combines a heavy-duty steel base platform, a robust chain-and-lift-bar apparatus, a high-capacity 1000 lb electronic load cell, and a handheld tablet running specialized data acquisition software (LEval application). The system measures peak force, average force, and force-over-time curves during controlled isometric lifts and pulls without requiring active movement of the load, drastically minimizing joint strain while capturing maximum voluntary contraction data. From assessing upper-arm and shoulder lifting capacity to executing full torso and back strength evaluations, the unit provides reliable metrics to determine safe return-to-work parameters and pre-employment physical qualifications.\u003c\/p\u003e\n\u003ch4\u003e\u003cb\u003eKey Benefits:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eHigh-Capacity 1000 lb Electronic Load Cell:\u003c\/b\u003e Accurately and reliably measures high-force isometric outputs during maximum voluntary contraction testing for heavy-duty industrial and clinical evaluations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNIOSH \u0026amp; Standardized Protocol Compliance:\u003c\/b\u003e Engineered specifically to satisfy established Jackson lift, pull, and torso strength protocols and the lifting task criteria outlined by NIOSH.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTablet-Based LEval Software Interface:\u003c\/b\u003e Handheld digital display provides real-time tracking of peak force, average force, and force-over-time graphs with automated data storage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSafe Isometric Testing Methodology:\u003c\/b\u003e Measures static force generation without dynamic load displacement, significantly reducing injury risks for recovering patients during maximal effort trials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMulti-Position Functional Testing:\u003c\/b\u003e Accommodates interchangeable configurations to evaluate grip, arm, shoulder, torso, and back strength using a secure chain and bar system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eObjective Return-to-Work Data:\u003c\/b\u003e Generates quantitative documentation essential for occupational health screening, functional capacity evaluations (FCE), and job-fit placement decisions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePortable \u0026amp; Professional Construction:\u003c\/b\u003e Compact, modular framework allows clinicians and industrial evaluators to transport and set up the testing system easily across different facility environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eLoad Cell Capacity:\u003c\/b\u003e Up to 1000 lbs (453 kg) electronic load cell precision sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHardware Components:\u003c\/b\u003e Steel platform base, adjustable chain system, lift\/pull bar, and electronic load cell assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eData Display \u0026amp; Capture:\u003c\/b\u003e Handheld Nexus\/Android tablet with pre-loaded LEval data collection software\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMeasured Parameters:\u003c\/b\u003e Peak force, average force, time-to-peak, and continuous force-over-time curves\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTesting Protocols Supported:\u003c\/b\u003e Isometric arm lift, shoulder lift, torso pull, back strength, and NIOSH-compliant lifting evaluations\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePower Requirements:\u003c\/b\u003e Rechargeable tablet battery and low-voltage electronic load cell power supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePrimary Applications:\u003c\/b\u003e Occupational health screening, industrial functional capacity evaluations (FCE), physical therapy rehabilitation, and ergonomic job-matching\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fabrication Enterprises","offers":[{"title":"Default Title","offer_id":67817273426164,"sku":"FEI-Z00469","price":7575.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2304\/8155\/files\/FEI-Z00469.webp?v=1792545303","url":"https:\/\/rescue-supply.com\/products\/jackson-strength-evaluation-system-for-isometric-force-and-functional-capacity-testing","provider":"Rescue Supply","version":"1.0","type":"link"}
