The SR-100

Instructions for Use

STEP 1

Go to the App store. Touch the Search Icon. Type in Accelera, touch Search. Look for Accelera with a white square with gold logo:

Download the app. You may need your Apple ID password to load this app. Some will need to update their iOS if using an older iPhone/iPad. iOS 14.0 or higher is required.

STEP 2

Open the box and locate the wireless charging unit. Locate the charging cable (under the box insert) and plug it into the charging unit and power supply. Plug the power supply into a standard outlet.

STEP 3

Locate the Accelera controller. Turn the On/Off switch to the On position to charge it.

STEP 4

Place the controller on the wireless charging unit. A blue light will come on indicating the unit is positioned correctly and charging. This should take about 1 – 1.5 hours. The blue light does not go off when fully charged. Leaving the unit on the charger too long will result in less than 100% charge. Once full the unit will use its standby power looking for the app to send instructions.

STEP 5

To use the Accelera SR-100, remove the controller from the charger. Power it off and back on again, then you can place it in the pouch on the wrap.

Look at the Accelera tag on the wrap and make sure the wire connector is coming out the side of the pouch at the end of the word Accelera (not the side). Connect the actuator lead to the magnetic connector on the controller and make sure the On/Off switch is in the ON position. When turning it on you will see a brief blue light that will go out if the app slider for intensity is still at zero.

STEP 6

Position the wrap on your body as needed. Most wearers use it around the ankle or lower half of the leg to address leg issues, or on the wrist or forearm just below the elbow for arm issues. On the arm, some find above the elbow more useful.

If you are having difficulty finding the best wrap location for you, a physical or occupational therapist may be helpful.

STEP 7

Launch the Accelera app on your phone.

STEP 8

You should see a device listed. You can rename the device as you wish, i.e. Left wrist, right knee, personal name using the Rename button on top right. Personal labels are stored on your device only. (if your controller is not turned on, you will not see it in the app).

STEP 9

Touch the device name and the control screen should appear. The output level is controlled by the slider button. Slide it to the right until you can barely feel the vibration. If there is no vibration, make sure there is a blue light lit on the magnetic connector. If not, reposition the magnet to connect to the controller again and use the slider again. Keep it below the number where you feel the vibration. Keep in mind that not all users do feel it, and some users describe the feeling as warmth, tickle or tingle rather than feeling vibration. More output is not better.

STEP 10

Touch Begin. The app will decrease the output level by 10% as recommended in most research with SR.

STEP 11

If you need to pause for any reason, simply touch Pause and then touch Resume when you are ready to continue.

STEP 12

Most users wear their device the majority of the day. When you are finished with it, power off and back on prior to placing it on the charger.

Wearing the SR-100

  • The controller slides in from the side of the pocket closest to the buckle
  • The magnetic connector should face the velcro strap side
  • The actuators that vibrate are inside the band as shown by the circles above in the drawing
  • The controller and its pocket should be on the outside, away from the skin. The smoother side with the actuators should be placed closest to the skin.
  • You may wear this device over top of lightweight clothing if you wish (i.e. light socks, thin sleeve or legging), however it may take slightly more intensity to get the same effect
  • Most wearers get the best results from wearing the device on their affected arm or leg closest to the end (forearm or wrist for arms, calf or ankle for the leg)

FAQs

The SR-100 is a lightweight, wearable wrap combined with a small power pack that provides Stochastic Resonance (SR) vibration signals to the wearer.  The power pack is wirelessly charged as needed on the included charger, and output is controlled with an app on your Apple iPhone or iPad.  A home kit(s) is sold to individuals, and clinical kits containing all the varied sizes and additional accessories to determine best fit are sold to healthcare professionals.

Low-level mechanical noise presented directly to sensory neurons can significantly enhance their ability to detect weak stimuli. This phenomenon of noise improving system performance is termed stochastic resonance (SR) and has been seen to occur in a variety of physical and biological systems. Subsensory mechanical noise (very low amplitude deflections applied) can improve the ability of sensory cells to detect mechanical stimuli such as pressure and vibration. Similarly, mechanical noise can also make sensory cells, which are responsible for joint angle and muscle force senses (proprioception), more sensitive.

There are no contraindications or precautions, and no adverse effects seen in the research, for any type of mechanical vibration, including stochastic resonance. You can wear it with any other device or brace you have been prescribed.

Most users wear it daily for a majority of the day. Consistent use is usually necessary to see best results. Plan to put it on when you get dressed and to wear it for all daily activities, not just when you think you may need it and not for a short time only just prior to the time of need. 

Length of time on a full charge is dependent on the level of stimulation used. At 50% of full output intensity, the battery life is typically 6 hours. Below the 50% stimulation setting battery life will improve. Charging time is between 1.0 and 1.5 hours to fully charge.

Many users wear more than one device (i.e. both ankles, one ankle and one wrist).  If you have one leg (or arm) significantly more impaired than the other, you may be able to use only one device on that more affected limb. If both are equally affected, you probably need two devices.

A single iPhone or iPad app can manage up to 4 devices at once.

Our wearable device is water resistant, not water proof.  This means you can be in the rain or wearing it if you sweat while exercising, however the components should not be submerged in water.  You cannot wear it in the shower, bathtub or while swimming.

Go to the Apple App store. Touch the Search Icon. Type in Accelera, touch Search. Look for Accelera with a white square with gold logo:  

Download the app. You may need your Apple ID password to load this app. Some will need to update their iOS software version if using an older iPhone/iPad. iOS 14.0 or higher is required.

Open the box and locate the wireless charging unit. Locate the charging cable (under the box insert) and plug it into the square charger. Plug the power supply into a standard outlet.

Turn the On/Off switch on the Accelera controller to ON (towards green) to charge .

Place the controller on the wireless charging unit. A blue light will come on indicating the unit is positioned correctly and charging. This should take about 1 – 1.5 hours. The blue light does not go off when fully charged. Leaving the unit on the charger too long will result in less than 100% charge. It is not recommended to leave it on the charger overnight or all day. Once full, the unit will use its standby power looking for the app to send instructions.

To use the Accelera SR-100, remove the controller from the charger. Power it OFF and back ON again, then you can place it in the pouch on the wrap. 

Look at the Accelera tag on the wrap and make sure the wire connector is coming out the side of the pouch at the end of the word Accelera (not the  side). Connect the magnet end of the wire to the magnetic connector on the controller and make sure the On/Off switch is in the ON position. When turning it on you may see a brief blue light that will not stay lit if the app slider for intensity is still at zero.  Use your app slider bar to increase the intensity above zero in order to see the blue light remain on.

Wear it on the arm or leg that you have challenges with.  It will not affect other limbs that are not wearing it. It is also not designed to help your limb when you are not wearing it, even though some people may experience carryover (meaning benefits last after taking it off).

Most people wear it somewhere below the knee for the leg and between the wrist and elbow for the arm.  There is no one correct place to wear it because sensors for vibration are located in every joint and throughout all muscles.  If you wear a brace with it, most wear it above their leg or arm brace. You cannot wear it on top of your brace. 

Position the wrap on your body as needed, and be ready to experiment with what works best for you. Not everyone has the same results wearing it in the same position, even when addressing similar conditions.

Start with it around the ankle or lower half of the leg to address leg issues, or on the wrist or forearm just below the elbow for arm issues. On the arm, some find above the elbow more useful.  Keep in mind, the body’s sensors that respond to vibration are sending messages to the brain so it knows where they are in space.  For this reason, best results are usually achieved wearing the device lower on the leg or arm you would like to affect.

If you are having difficulty finding the best wrap location for you, a physical or occupational therapist with knowledge of using vibration may be helpful.

Position the flat side of the wrap against your body with the controller pocket on the outside away from you. While wearing over light clothing (thin socks, lightweight cotton sleeve) is okay, it is not advised to place heavy layers of fabric between you and your wrap. Skin contact is not required.

Note: see setup videos for further assistance in how to put the wrap on your body.



  • The controller slides in from the side of the pocket closest to the buckle
  • The magnetic connector should face the velcro strap side

You do not need to have the IPhone or iPad near the device except to set the amount of output when you turn it on. Once it is set, the device will disconnect from the app and continue to run at the set intensity until you power it off or deplete the battery. You will need your iPhone or iPad to re-set the device after each time on the charger. Do power OFF and back ON between wearing the device and charging it, then between charging and wearing it again.

Yes, you can wear it anytime you want as long as it is not in water (i.e. no bathing/showering with it on).  Some users find greater benefits with both day and night wear.  Some will alter the position of the device for nighttime comfort.  (i.e. wearing on the ankle in daytime, but foot or calf at night).  Note: wearing it at night is not a substitute for daytime wear to gain functional benefits with proprioception and therefore mobility.

Warranty is 1 year on the power pack and 90 days on the wrap.

When you have the device on the body part where you would like to wear it, select that device on your app.  If you do not see the device as an option, make sure the device is switched to the ON position (toward green dot).  (NOTE: Bluetooth must be turned on in your iPhone/iPad’s settings).  If you would like to rename the device you can do that with the RENAME button in the top right of the screen after you select it.  Doing so will help users of multiple devices tell them apart without memorizing ID numbers. 

Using the intensity slider, gradually slide it up a little at a time to see if you can feel it.  Move it by 5-10 numbers at a time and take your finger off the slider to see if you notice the vibration.  Some describe it as a tickle or warmth rather than vibration.  If you cannot feel it at 100 (maximum level) that is ok.  If you can feel it, stop at that number and adjust it 1-2 numbers lower at a time until you find the number where you no longer feel it.  Press BEGIN.  That button will say PAUSE now, meaning if you press it, the output will pause.  If you press PAUSE, the button will change to RESUME to indicate if you press it again the output will continue.

While a part of the process to set up the device is to try to find the level of output you are able to feel, you should not be able to feel it while using it during activities, and many users are not able to feel it at all.  For those unable to feel the vibration on the body part where they need to use the device, it can be helpful to turn your device on while still holding it in your hands, and then put it on your arm or leg to use it once you know the vibration is on. 

If you cannot feel it (and this is common), start with the unit at 100 and tap begin on your app.  Use it at this level repeated days in a row until you know what benefits you experience with the device.  Once you know what it does for you, you can experiment with a lower setting to preserve battery life using the lower setting, if results are equivalent. 

Research shows the best results are achieved when the device is worn subsensory, meaning you are not consciously aware of the vibration while wearing it.  More has not been shown to be better, and there is no correlation between feeling it and getting functional improvement while wearing it.  You know it is working when your proprioception, and therefore function, is better with it on than without it.  In many cases, this improvement is not immediately recognized.  If you are having trouble determining the benefits you get when wearing the device, it can be helpful to have someone other than you help observe or take videos for you of the difference between a day not wearing the device and a day wearing it.  Physical or occupational therapists, trainers, and others familiar with vibration and your abilities can also do testing before and after to determine differences.  NOTE: If you are participating in before and after testing, most will need to do those tests on different days.  If you have already worn the device on a day, the BEFORE is not valid as the device has already affected your body’s sensory system.  Since many users do not get immediate results, doing the AFTER tests minutes after putting it on is not always a good indicator of how well the device will help a user with longer term use.

No, stochastic resonance does not make your body do something it cannot already do.  The vibration activates receptors in the joints and muscles which increases sensory signals to the brain.  This increased awareness gives your body a sense of where it is in space.  Think of it as having a starting place from which to give directions.  Once your brain knows where your leg or arm is located relative to the environment around it, then the brain can better decide what commands to give and when to give them.

As mentioned above, Stochastic Resonance vibration does not make your muscles do things they would not otherwise do.  However, if you are using muscles more often or more correctly, then they have a chance to strengthen.  Think of it like going to the gym to exercise – the more correctly you perform the exercise and the more times you do it, the more you build up your strength.
