Model: Evaluator General Description The Evaluator is a system used to assess physical capacity of specific human functions. The system can be easily transported from one location to another. The system includes load cells, mechanical adapters for various applications, tool communication hardware, software, range of motion devices (ROM), and storage/transport cases.
Page 6
Operating Principle The Evaluator is a device that supplies a means for assessing strength and range of motion through the use of a hand grip, pinch strength, ROM devices and pull/push devices. The tools include a pinch gauge, hand grip, a portable load cell and other. The Evaluator measures isometric push/pull forces applied to the tool by the client and the duration of time force is applied.

02 - Heart Rate Systems HEART RATE SYSTEMS There are two heart rate system options for the Evaluator; a chest strap system and a bluetooth system utilizing a wrist-watch. The software accomdates both systems, but only one can be used for data collection at a time. Refer to the EvalTech Software Operator’s Manual for information on choosing which system to use.
chapter 02 - Heart Rate Systems II. SETTING UP THE HEART RATE SYSTEM Step 1. With the elastic strap attached, have the client secure the monitor to his or her chest just below the chest muscles and directly against the skin. The Polar logo should be centered on the chest and in an upright position (Figure 2-2).
chapter 02 - Heart Rate Systems Step 2. If you haven’t done so already, attach the antenna to the Portable Dock & Transmitter. Step 3. Make sure the batteries are in the Transmitter and turn the Transmitter on using the switch on the side farthest from the antenna (Figure 2-3).
• Replace the rechargeable batteries every 6 months if used frequently and every year if used occasionally. • Replace the Polar Heart Rate chest strap every 2 years or 2500 hours of use. Contact BTE at 410-850-0333 or 800-331-8845 for a replacement.

chapter 02 - Heart Rate Systems then re-enter the screen. B. ABNORMAL HEART RATE VALUES There can be several reasons for abnormal or irregular readings during testing. Due to the same reasons, heart rate may stay at the same value for a long time or the heart rate stays at zero (0).
chapter 02 - Heart Rate Systems 2. WEAR AND TEAR OF THE MONITOR Proper care of the monitor after use ensures longer service life for the monitor. • Wash the monitor regularly after use. It should be washed with a mild soap and water solution.
chapter 02 - Heart Rate Systems the other monitors. 6. STATIC ELECTRICITY, TECHNICAL SPORTSWEAR, AND SPECIAL CONDITIONS If the humidity of the air is low a fluttering shirt may rub the monitor and generate static electricity. This causes additional signals, especially if the contact between skin and monitor is poor.
chapter 02 - Heart Rate Systems SECTION 2b - BLUETOOTH 4.0 HEART RATE SYSTEM I. INTRODUCTION The Bluetooth 4.0 Heart Rate System is comprised of the Mio Alpha Heart Rate Monitor and USB Bluetooth 4.0 low energy radio adapter. Additional item includes the USB charging adapter that comes with the Mio Alpha.
chapter 02 - Heart Rate Systems A. SETTING UP THE BLUETOOTH 4.0 HEART RATE SYSTEM If not done already, insert the Bluetooth USB adapter into an available USB port on the front of the computer. Step 1. Fasten Mio ALPHA tightly on your arm above, not on, the wrist bone. Note: Wear it higher on the forearm you have a small wrist.
chapter 02 - Heart Rate Systems II. MAINTENANCE AND CARE • Recharge the battery at least once every 6 months. • Do not expose the watch to high temperatures. • Use the watch in the temperature range of 5°C to 45°C (41°F to 113°F). •...
chapter 02 - Heart Rate Systems E. WATCH BEEPING DURING USE • This will have no impact on data collection in EvalTech. This may occur if the persons heart rate is exceeding the preset factory defaults of “Training zones” on the watch – or if settings have been changed via the Set Toggle button on left side of the watch.

chapter 03 - Dual Inclinometer DUAL INCLINOMETER I. INTRODUCTION The Dual Inclinometer is used to evaluate range of motion while allowing for sections to be tested in isolation. This is accomplished by a sensor in each Inclinometer side calculating the rotational displacement and subtracting or adding the two values to arrive at a true range of motion value.
chapter 03 - Dual Inclinometer C. UTILIZING ONE INCLINOMETER SIDE If you wish to use only one Inclinometer side, then you must use the master side. Simply remove the coiled link cable from the master side and begin testing. Refer to the Cervical Rotation section of this chapter for a pictorial example.
chapter 03 - Dual Inclinometer • Lateral Thigh – Locate the Greater Tuberosity and place the tip of the Inclinometer just inferior. • Anterior Lower Leg –Locate the Tibial Tubercle and follow the anterior ridge of the tibia inferiorly approximately two-thirds down the lower leg. For isolated joint movement, use a single Inclinometer side by placing it distally in the plane of movement of the joint being assessed.
chapter 03 - Dual Inclinometer 2. EXTENSION Step 1. Align the Inclinometer sides in the sagittal plane and place one of the sides on the top of the head (Figure 3-3). Step 2. Place the other side on T1 (Figure 3-3). Step 3.
Use a single Inclinometer side for cervical rotation testing. Step 1. Have the client lie in a supine position (this will stabilize the client’s shoulders). The shoulders should be exposed in order to allow the evaluator to note any excessive shoulder rotation.
chapter 03 - Dual Inclinometer B. THORACIC RANGE OF MOTION Since evaluating the thoracic spine is quite dependent on the individual’s posture, it is best to have the client use a military type stance. This will help to minimize the client’s kyphosis. 1.
chapter 03 - Dual Inclinometer 3. ROTATION Step 1. With the client in a standing position, instruct them to flex forward until the thoracic spine is in as horizontal a position as possible (Figure 3-7). Step 2. Align the Inclinometer sides in the axial and vertical planes and place one of the sides on T1 (Figure 3-7).
chapter 03 - Dual Inclinometer C. LUMBROSACRAL RANGE OF MOTION 1. FLEXION Step 1. Align the Inclinometer sides in the sagittal plane and place one of the sides on T12 (Figure 3-8). Step 2. Place the other side at S1 (Figure 3-8). Step 3.
chapter 03 - Dual Inclinometer 3. LATERAL FLEXION Step 1. Align the Inclinometer sides in the coronal plane and place one of the sides on T12 (Figure 3-10). Step 2. Place the other side at the sacral midpoint (Figure 3-10). Step 3.
chapter 03 - Dual Inclinometer The straight leg raise on the tightest side should be within 10 degrees of the total hip motion (i.e. hip flexion + hip extension). V. DETERMINING THE DEGREE OF ANKYLOSIS When the degree of ankylosis needs to be documented, the steps listed above must be slightly adjusted: Step 1.

chapter 04 - Goniometer GONIOMETER I. INTRODUCTION The Goniometer is used to evaluate extremity range of motion. The tool uses a sensor to calculate the amount of displacement in degrees and arrive at a true range of motion value. Included with the Goniometer are three different types of arms: 2 small arms, 1 medium arm, and 1 long arm (Figure 4-1).
chapter 04 - Goniometer III. PRE-DEFINED TESTS & TESTING TEMPLATES The EvalTech software includes several pre-defined tests and testing templates. For information on assigning and administering tests in the software, refer to Chapters 4 and 5 of the EvalTech Software Operator’s Manual. The following extremities may be tested with the Goniometer: •...
chapter 04 - Goniometer B. DETERMINING THE DEGREE OF ANKYLOSIS When the degree of ankylosis needs to be documented, the testing procedure must be slightly adjusted: Step 1. Align the Goniometer arms and place them on a wall or tabletop. Take the first reading by pressing the black button.

Through the use of multiple attachments and protocols, a client’s hand grip strength can be evaluated through several different scenarios.
chapter 05 - Hand Grip Dynamometer C. HAND GRIP & CLIENT POSITIONING Verify the grip is properly positioned: 1. The end of the Hand Grip base where the cord attaches should be facing down (Figures 5-3 & 5-4). 2. For the concave grip, the thicker end of the grip, which has the U-shaped end, must be facing up such that the pointer finger comes in contact with it.
chapter 05 - Hand Grip Dynamometer III. PRE-DEFINED TESTS & TESTING TEMPLATES The EvalTech software includes several pre-defined tests and testing templates. For information on assigning and administering tests in the software, refer to Chapters 4 and 5 of the EvalTech Software Operator’s Manual. A.
