MUSCLE STRENGTH AND FATIGUE TESTING

The LifeForce QMA Series Isokinetic Testing and Evaluation System is a tool that will provide objective substantiation and documentation of your patient's progresss through therapy.  You may find it to be beneficial in research when applied to drug therapy, fatigue studies or compiling population normals.

The QMA System is registered with the FDA as a Class II medical device:

                                                   In Research
QMA is currently the muscle assessment system of choice in university hospitals, clinics and institutions in Europe, the Middle East, and North America - Canada and the United States, in the continuing research of neuromuscular and motor neuron diseases.

Several articles are published each year in peer review publications from research utilizing the QMA System.

                                                   In Healthcare        
QMA is used by healthcare professionals to evaluate the physical rehabilitative progress and functional capacity of patients, to document the percentage change from a previous visit and to compare each muscle or muscle group tested to an expected "normal" - based on age, gender, and body mass index (BMI).

Reports may be generated that compare your patients?visit to a previous or baseline visit, and include the measured effort and the percentage change of each muscle tested.  Calculations may also be made comparing your patients? efforts to those of a theoretical Normal -based on age, gender and BMI.   Normal predictive calculations are based on publications by Mathiowetz, Bohannon, etc. 

QMA provides documentation in the diagnosis of neuromuscular systemic diseases; such as, Amyotrophic Lateral Sclerosis (ALS), Myasthenia Gravis (MG) and Myotonic Dystrophy, where the primary indicators are loss of muscle strength (muscle atrophy) and excess fatigue.   Early utilization of QMA may confirm the diagnosis in initial stages.

Diagnostic and assessment of swallowing and speech impediment may be assisted with tongue strength instrumentation.    May be used with stroke patients to measure their rate of recovery.

 
Hand Held Myometry - Hand held input instruments with analog output (HHM) may be used to replicate manual muscle testing (MMT).    Categories of tests include strength, and static and dynamic fatigue.  HHM provides an increased range of muscles and muscle groups to be tested and assessed than fixed myometry. 
When HHM is utilized to assess larger muscle(s) or muscle groups, accuracy may be compromised due to the point of resistance established and maintained by the tester being moved or compromised.   <More>

Fixed Myometry - Preferred when testing larger muscles or muscle groups, or muscle fatigue.  Tests may be constructed, conducted and analyzed on any muscle or muscle group that can be isolated and effort exerted against a fixed point.  Categories of tests include strength and static and dynamic fatigue.  <More>

QMA PORTABLE SYSTEM - Hand Grip Strength, Hand Held Myometry input equipment and a Netbook or Notebook - complete, portable, accurate and easy to use.  Complete documentation of your patients progress with your comments and evaluation makes this a complete assessing system.    <More>

Components of the system 
 describes and illustrates components of the QMA system.

Hand Grip  - A hand dynamometer with analog output to measure hand grip strength and fatigue.

Hand Held Myometry (HHM) Unit - Permits the testing personnel to assess most muscles or muscle groups, replicating manual muscle testing (MMT).

Pinch Test - Key, Tip and Palmar strength and fatigue with analog output.

Individual Finger Strength - adjustable from 1" to > 4"  from 1 to 100 Lbf instrument with analog output. 

Tongue Appliance - Test tongue strength with analog output.  (Speech Impediment and Bulbar paralysis)

Timed Test - Integrated stopwatch acquires elapsed time of test, (i.e. three stair climb, etc.)

Direct Data Input  - Other data may be entered as a test - examples, include: blood pressure, weight, height, any required or desired data taken during the visit.  

Electronic Medical Reporting  - Patient Evaluation and Progress Documentation - NEW
Complete professional reports are automatically populated for patient evaluation:  Document the longitudinal rehabilitative progress of your patients, automatically calculates percentage change from previous visits, and anticipated "normal"  based on age, gender & BMI, and percentage deviation from normal.   
 US and European formats are illustrated.

DATA MANAGEMENT
EXPORT TO EXCEL INFO & EXAMPLES  All acquired data may be compiled, queried, and exported seamlessly to MS Excel for comparative longitudinal analysis.
