The HUMAC® NORM™ is an advanced isokinetic dynamometry system designed for objective muscle performance assessment, musculoskeletal rehabilitation, training, and scientific research.
Manufactured by Computer Sports Medicine, Inc. (CSMi), the HUMAC NORM enables professionals to quantify muscular performance and objectively monitor the progress of patients and athletes, providing valuable data to support decisions related to treatment, rehabilitation progression, and return to work or sports activities.
With support for 22 isolated movement patterns, the system enables assessment and training of multiple joints and body segments, including the shoulder, elbow, wrist, hip, knee, ankle, and spine.
Objective Muscular Performance Assessment
One of the key advantages of the HUMAC NORM is its ability to transform muscular performance into objective and reproducible data.
Dynamometry enables professionals to analyze muscular behavior during different types of contraction and compare results between limbs, sessions, and different stages of the recovery process.
According to CSMi, this information can help document the need for treatment, monitor patient progress, and provide objective data for decisions related to returning to work or sports.
Four Resistance Modes
The HUMAC NORM provides four primary resistance modes, allowing the system to be adapted to different stages of assessment and rehabilitation.
Isokinetic: enables exercise at a controlled angular velocity, including concentric and eccentric applications. It can be used for both assessment and strengthening, as well as deceleration training.
Isometric: maintains the joint at a specific position for strength assessment or training at selected joint angles.
Isotonic: uses a simulated mass mode for dynamic exercise, providing additional possibilities throughout functional progression.
Passive: moves the body segment in a controlled manner and can be incorporated into mobility and movement progression activities.
22 Movement Patterns
The HUMAC NORM includes accessories that enable professionals to perform 22 isolated movement patterns across different regions of the body.
The system supports movements involving the:
Shoulder;
Elbow;
Wrist;
Hip;
Knee;
Ankle;
Spine.
CSMi also offers optional accessories for applications such as trunk flexion/extension, work simulation, and closed kinetic chain movement patterns.
Isokinetic Assessment
In isokinetic mode, the dynamometer controls movement velocity while recording the user's muscular response.
This methodology enables standardized muscular performance assessments and provides quantitative data that can be used to monitor progress throughout rehabilitation or training.
The system supports conventional isokinetic testing, concentric/eccentric protocols, and other specific assessment configurations.
Concentric and Eccentric Training
The HUMAC NORM supports both concentric and eccentric exercise, providing greater flexibility for strengthening and functional recovery programs.
This capability allows professionals to develop specific protocols according to the objectives of each rehabilitation stage, ranging from controlled activities to more advanced exercises focused on restoring function and performance.
Passive Motion and Mobility
The passive mode expands the system's capabilities throughout different stages of the therapeutic process.
In this mode, the system can assist with developing the mobility required by the patient, from simple controlled movements to more complex movement patterns, including applications related to PNF patterns.
Proprioception and Neuromuscular Control
In addition to strength assessment, the HUMAC NORM provides capabilities for proprioceptive assessment and training.
Its protocols can be incorporated into programs designed to develop neuromuscular control, joint coordination, and functional progression.
This expands the system beyond traditional strength testing, providing additional possibilities for comprehensive rehabilitation and performance programs.
HUMAC Software and Reporting
The system uses specialized HUMAC software for managing protocols, tests, exercises, and results.
Professionals can create customized protocols consisting of different exercise sets and parameters. According to the manufacturer's documentation, a protocol can contain up to 25 sets, enabling assessment and training sessions to be structured according to individual requirements.
For clinical and scientific applications, the software also provides documentation and reporting capabilities. CSMi states that the system includes more than 30 built-in reports, providing comprehensive information for analysis and documentation.
Bilateral Comparison and Progress Monitoring
Standardized assessment protocols make it possible to compare performance between opposite sides of the body and monitor changes over time.
This information can help professionals identify bilateral deficits and track changes throughout the rehabilitation process.
Objective results can also complement clinical criteria used when determining progression and readiness to return to activity.

Designed for Clinics, Sports Centers, and Research Laboratories
The HUMAC NORM is designed to support a wide range of professional environments.
In physical therapy, it can be incorporated into different stages of orthopedic rehabilitation programs. In sports performance settings, it can support the assessment and rehabilitation of extremity injuries. In orthopedic practices, it provides objective data that can complement functional progress monitoring. In laboratories and universities, it provides reproducible measurements and documentation tools for human performance research.
Designed for Assessment and Rehabilitation
The HUMAC NORM consists of three primary components: the dynamometer, electronics module, and patient positioning chair with monorail system.
This configuration allows the user to be positioned according to the body segment and movement pattern being assessed or trained.
The system also incorporates adjustable mechanical range-of-motion stops (AMROM), designed to streamline patient setup and establish mechanical movement limits.
From Objective Assessment to Return to Function
The HUMAC NORM combines dynamometry, multiple resistance modes, specialized software, and assessment protocols to provide a comprehensive platform for muscular analysis and training.
By providing quantitative information about patient or athlete performance, the system complements clinical assessment with objective data, supports progress monitoring throughout rehabilitation, and helps establish measurable parameters for different stages of functional recovery.
For healthcare, sports performance, and research professionals, the HUMAC NORM provides an advanced solution that integrates assessment, documentation, training, and research within a single platform.
