There are many research studies on the Shaker exercise, the Chin Tuck Against Resistance Exercise (CTAR), and the Jaw Opening Exercise, which support the use of the ISO Swallowing Exercise Device in dysphagia therapy. There have been some very impressive research studies in this area recently. Please see our Research page for more information.

Success Stories

Man Who Could Not Even Swallow His Saliva: 

He was a stroke victim, 18 months post CVA, with a PEG, complained of painful dry throat, but coughed severely when he tried to swallow, so he spit out all saliva into a cup, for 18 months. Within 2 weeks of therapy with the ISO-SED, he was able to swallow without coughing, and gradually progressed to tolerating a p.o. diet.

Woman Who Began Coughing and Vomiting During Meals:

She was a stroke victim, 3 years post CVA. She said that it felt like the food just would not go down, and would eventually make her start coughing and often resulted in her vomiting. This problem gradually declined in frequency and severity over 8 weeks of therapy with the ISO-SED until she was tolerating a regular diet and thin liquids with only an occasional mild cough/clear.

Man Who Could Not Initiate the Swallow:

He had Parkinson's disease and began having difficulty triggering the swallow response several times per meal. He said he would be ready to swallow and just couldn't get it to start, for multiple attempts and then he could eventually swallow. He began using the ISO Swallowing Exercise Device daily and had therapy 3x per week. Within 6 weeks, he no longer had this problem.

Another Man Who Could Not Swallow His Saliva:

He was on a PEG tube, began coughing and choking when eating or drinking for unknown cause 6 months prior. PEG tube was inserted 3 months prior to beginning therapy with the ISO-SED. He had been to doctors and therapists, and even to the Mayo Clinic and nobody could help him. He spit out his saliva into a bucket all day and all night. With therapy, his swallow gradually improved, as evidenced by steadily decreased need to spit out saliva. After 10 weeks of therapy, he no longer had to spit out saliva and within 3 more weeks, he was tolerating a soft diet and thin liquids with only an occasional cough.  

Man Who Was NPO with a PEG Tube:

He was a stroke victim with dementia, who had been NPO for over a year, despite having dysphagia therapy, including Vital Stim in rehab and home health care. He received dysphagia therapy with the ISO Swallowing exercise device 3x per week for 30 minutes. After 12 weeks of therapy, he was able to tolerate pureed foods and nectar thick liquids, given small bites and small sips, without signs or symptoms of aspiration. 

Man With Parkinson's Disease Who Was Coughing with Thin Liquids:

He had Parkinson's disease and Alzheimer's disease. He presented with a low volume voice, slurred speech, and intermittent coughing with intake of thin liquids. He received dysphagia and voice therapy with the ISO Swallowing Exercise Device twice a week for 8 weeks. The ISO Swallowing Exercise Device was used for vocal cord adduction exercises and laryngeal elevation exercises in addition to Chin Tuck Against Resistance (CTAR) and Jaw Opening Against Resistance (JOAR) exercises for dysphagia. Within 4 weeks, he no longer coughed with thin liquids and by the end of treatment, his vocal quality improved to within normal limits.

Woman Who Was Having Difficulty Swallowing Pills:

Due to normal aging, she gradually lost strength in the muscles needed for swallowing and she began having difficulty swallowing her pills and feeling like they got stuck in her throat. She was seen for dysphagia therapy using the ISO Swallowing Exercise Device twice a week for 30 minutes per session for 4 weeks. By the end of treatment, she was able to swallow her pills with no problems.

The ISO Swallowing Exercise Device

The ISO Swallowing Exercise Device is a flexible exercise device used to strengthen the suprahyoid muscles in the throat with Chin Tuck Against Resistance (CTAR) exercises and Chin to Chest (CtC) or the Jaw Opening Against Resistance (JOAR) exercises. 

The ISO Swallowing Exercise Device is easy to hold, even with just one hand. It is held at the lower chest area (or abdomen level for children), which is much less strenuous than holding the arms up at the neck level, and it is specifically designed to require as little strength and effort as possible to hold it in precisely the right position to provide the optimal resistance for the exercises. This allows patients to thoroughly fatigue the suprahyoid muscles before the arm muscles fatigue.

The ISO-SED contours to the area under the jaw, to maximize the effectiveness of the jaw opening against resistance exercise. It provides a wide range of variable resistance, depending on the strength each patient is able to exert. The more it bends as pressure is applied, the more resistance it provides. The ISO-SED allows the patient to have a full range of motion during exercises, beginning with resistance at a chin elevated position, which helps to isolate the suprahyoid muscles.

We also offer a professional package with removable chin pad covers and alcohol cleaning wipes for use with multiple patients. It all fits in a compact, professional, protective carrying case.

Patients love using the ISO-SED. It is interesting, fun, and very motivating. High motivation, ease of use, and optimal design makes the ISO-SED a tool no dysphagia speech language pathologist should ever be without, and every dysphagia patient should own and use daily!

"I am a co-inventor of the ISO-SED and I am a speech language pathologist with over 19 years of experience. I have been using the ISO-SED with patients since 2010. Since I started using the ISO-SED, I have consistently seen much better and faster improvements in swallowing than I ever saw in patients before I started using the ISO-SED. My patients love using it, and usually ask if they can keep it after they try it the first time because they want to use it in between sessions!"                                                                  - Jolie Parker, M.S.CCC-SLP 

"I know this device is going to help many people." - Steve Blackburn, M.D.

"...I have previously purchased several of your devices and have allowed colleagues to "borrow" them; needless to say, I never got them back :( I need to be a little more stern with the terms "borrow". Thanks again for creating this! Take care!"                                                                 - Speech Language Pathologist

"...We highly recommend the use of the ISO device as an essential device to regain the ability to swallow properly."                   - Customer

"...I should also share that clinically speaking, this device has allowed two of my patients to have their PEG tubes removed!"           - Speech Language Pathologist

"I want to congratulate you on the ISO. It has done wonders for my wife, who had acute dysphagia problems due to radiation treatments. It has helped to greatly improve her swallowing, and her doctor is very pleased with her progress. She is also pleased, considering the fact that her first Speech Therapist wanted to put in a feeding tube... "                                                       - Customer 

"I am an SLP in Palm Bch. County, FL who has a home health pt. equipped with an iso-S.  He loves exercising with it and I have felt that this tool can benefit dysphagia pts."                                                          - Speech Language Pathologist

"..I think that you have a great product and it has been very helpful to me."

                                                                                   - Customer 

"I am amazed at how much my husband’s speech has improved since you started giving him speech therapy.  The ISO has increased his volume so quickly that I was startled to hear a “voice” while standing in my walk in closet.  I couldn’t believe it was Maynard’s voice, but it was!..."         - Arline Kern

"I was curious if you had a wholesale price so as to purchase ISO devices for the outpatient center where I work to resale to patients.  Often times patients after trying the device that I have on site want to be able to leave with one..."

                                                                                  - Speech Language Pathologist

"...A few months ago, we had recommended to a friend of ours in Appleton, WI, whose husband had dysphagia and she bought an ISO from you. They are very pleased with the results from using it. He is now eating after passing the swallowing test."                                                      - Customer
