Indications for Use
The AMES Therapy Device is a rehabilitative exercise therapy device that uses assisted movement to measure, evaluate, exercise, re-educate and strengthen muscles, and to increase joint range of motion. It also uses muscle vibration for muscle relaxation.
Device Story
Electromechanical therapy device; features 3 motion assemblies (ankle, wrist, thumb/fingers) and 5 therapeutic vibrators. Patient seated in conventional chair/wheelchair; limb attached to device. Provides assisted movement to limb; applies simultaneous vibration to antagonist muscle. Visual feedback unit displays force (torque) on touch screen; patient targets specific torque levels to encourage agonist muscle work. Used in clinical settings by therapists. Data collected includes therapy duration, performance, active range-of-motion, and strength. Therapist uses data to monitor rehabilitation status, adjust treatment regimens, and determine therapy efficacy. Non-invasive; no electrical stimulation or heat application.
Clinical Evidence
Safety data from clinical evaluations focused on skin integrity. No efficacy clinical trials reported. Bench testing included UL 60601-1 and IEC 60601-1-2 compliance, biocompatibility testing (non-irritating, non-sensitizing, non-cytotoxic), and design verification.
Technological Characteristics
Electromechanical device; 3 motion assemblies; 5 therapeutic vibrators; visual feedback touch screen. Non-invasive; no electrical stimulation or bioelectric potential recording. Complies with UL 60601-1 and IEC 60601-1-2. Biocompatible patient-contacting materials.
Indications for Use
Indicated for patients requiring rehabilitative exercise therapy to measure, evaluate, exercise, re-educate, and strengthen muscles, and to increase joint range of motion, as well as muscle vibration for muscle relaxation.
Regulatory Classification
Identification

#### 4. Device Description:
The AMES Therapy Device is an electromechanical physical therapy device that combines 3 motion assemblies (one for the ankle, one for the wrist, and one for the thumb-and-fingers), 5 therapeutic vibrators, and a visual feedback unit, all contained in one device. The patient is seated in a separate conventional chair or wheelchair so that the appropriate limb can be attached to the AMES Therapy Device for therapy.
The AMES Therapy Device includes assisted movement to the limb being treated and applies simultaneous vibration to the antagonist muscle. The device provides visual feedback to the patient to indicate whether he/she is producing the requisite force (torque) in assisting the device's motion and encourages the patient to keep working the agonist muscle. The feedback also includes a force (torque) "target," set to a level by the the patient can achieve repeatedly during therapy without becoming too fatigued, but that is also moderately challenging. The torque produced by the patient is indicated on the video touch screen.
Testing and reporting on the patient's therapy and functional status can be performed at each therapy session prior to or following administration of therapy. Data for each session include therapy delivery (date, duration, performance) and test results. Two tests are carried out during the treatment session to measure: 1) active range-of-motion, and 2) strength. These test scores permit the therapist: (i) to determine each patient's baseline status at the time that the patient first receives the AMES therapy, and (ii) to monitor changes in rehabilitation status during the course of the patient's therapy. This testing enables therapists to modify the treatment regimen in response to observed improvements and to determine when is no longer benefitting from the therapy.
The AMES Therapy Device is non-invasive and there is no electrical stimulation involved in the device, nor any recording of bioelectric potentials. No heat is applied by the AMES Therapy Device.
#### 5. Intended Use/Indications for Use:
The AMES Therapy Device is a rehabilitative exercise therapy device that uses assisted movement to measure, evaluate, exercise, re-educate and strengthen muscles, and to increase joint range of motion. It also uses muscle vibration for muscle relaxation.
#### 6. Comparison with the Predicate Devices:
Because the AMES Therapy Device combines the functions and characteristics of different physical therapy devices, multiple predicate devices are presented. Like the System 4 device, the AMES Device is intended to exercise, measure, evaluate and increase the strength of muscles and increase the Range of Motion (ROM) of joints. Like the Vibracussor device, the AMES Device is intended to relax muscles using vibration. The AMES Therapy Device uses isokinetic principles like the System 4 device to deliver therapy, and uses vibration like the Vibracussor device to deliver therapy to relax muscles. Based on these comparisons, the AMES Therapy Device is substantially equivalent to the predicate devices in intended use, indications for use, and device function and features.

#### 7. Non-Clinical Testing:
Testing has been conducted to UL 60601-1 Standard for Safety for Medical Electrical Equipment, Part 1: General Requirements for Safety and IEC 60601-1-2 Medical Electrical Equipment - Part 1-2: General Requirements for Safety: Electromagnetic Compatibility - Requirements and Tests.
Biocompatibility testing for patient-contacting materials is included that demonstrates that the patient-contacting materials are not irritating, sensitizing, or cytotoxic.
Design verification testing was performed on fully functional AMES Therapy Devices to demonstrate that the AMES device performed as designed and met its specifications.
#### 8. Clinical Testing:
Safety data from clinical evaluations of the AMES Therapy Device were used to evaluate the safety of the device with respect to skin integrity.
#### 9. Conclusions:
Non-clinical testing showed that the AMES device performs as designed. Based on the information presented in this submission, we believe that the AMES Therapy Device is substantially equivalent to the predicate devices in intended use, indications for use, and device function and features.
