Prenatal testing for Down Syndrome

We are seeking parents of a child with Down Syndrome to participate in a discussion group. Your child can be of any age and we are seeking the input of both mothers and fathers. Both parents can join the study or just one parent can join. We want to ask questions about what you think about the testing of pregnant women to see if their child has Down Syndrome. Sessions will take place at Lidcombe, Camperdown and Richmond so you can attend any session that is convenient for you.

Treatment for preschool children with speech problems

Does your preschool child have problems saying sounds correctly?
Children who have speech problems tend to pronounce words in a less mature way for their age (e.g., “I wike paghetti”). Left untreated, speech problems can lead to difficulties in learning to read and forming friendships.
We are investigating the role of parents in treating speech problems. We are testing a parent-friendly treatment for speech problems in children. The treatment, multiple oppositions, is a commonly used treatment for preschool-aged children, and is normally delivered solely by speech pathologists. We are interested in seeing if parents are able to deliver some of the treatment at home with their child, with training and support from a speech pathologist.

Childhood Apraxia of Speech (Dyspraxia)

If you are an adult who was diagnosed with CAS when you were a child we would like you to complete a survey on the therapy you received as a child, your education and employment and your family history of speech, language and literacy difficulties.
We are looking for people over the age of 18 who were diagnosed with CAS when they were children. You can live in any country and do not need to have speech problems currently.
If you are interested in finding out more please go to the survey webpage.

Please feel free to share this information with anyone you think might be interested in the research.

You can also get more information about childhood apraxia of speech or this survey by emailing or phone (02) 9351 9747.

Are you a Speech Pathologist who treats Muscle Tension Dysphonia?

Voice therapy is the treatment of choice for Muscle Tension Voice Disorders. However, little is known about what actually occurs during therapy and what ‘parts’ of the therapeutic process are responsible for positive treatment results. We want to explore what Speech Pathologists do during therapy when working with people who have Muscle Tension Voice Disorders.

Speech Pathologists can participate if they meet the following criteria:
- Are practicing members of Speech Pathology Australia and;
- Have a current caseload that includes assessing and treating people with Muscle Tension Voice Disorders.

For further information about this study view our flyer and Participant Information Statement.

Do you experience voice problems due to muscle tension?

Voice therapy is the treatment of choice for voice disorders caused by muscle tension. However, little is known about what actually occurs during therapy and what ‘parts’ of the therapeutic process are responsible for positive treatment results. We want to explore what Speech Pathologists do during therapy when working with people who have Muscle Tension Voice Disorders.

If you are thinking about or currently seeing a Speech Pathologist for voice related concerns, you may be eligible to participate in this study.

Heat sensitivity in individuals with Multiple Sclerosis

Are you healthy and between the age of 40 and 60? You are invited to take part in study investigating the mechanism of heat sensitivity in individuals suffering from Multiple Sclerosis. We are currently recruiting healthy male and females (age: 45 to 60 years old) to be part of our control group for this study. By comparing their ability to regulate their body temperature to that of healthy controls, the overall aim of the study is to elucidate the mechanisms that induce heat-related fatigue and a worsening of symptoms in individuals suffering from Multiple Sclerosis, when their body temperature increase as a result of physical activity and hot ambient temperatures.

The time commitment is ~1h for the first session, and ~2h for the two following sessions. We provide our participants with a parking permit on Campus. However, should it be difficult for you to drive to the campus, we can provide a taxi voucher. With regards to scheduling testing sessions, we are quite flexible and can accommodate any need in terms of times and days.

BIP: Brief Behavioural Intervention for Peripheral Arterial Disease

Do you experience pain in your legs when walking? Participate in a free study researching the effects of brief behavioural intervention and improved physical activity levels in adults who experience pain in their legs when walking due to peripheral artery disease.

Our study team is looking for patients who have blocked leg arteries, are ambulatory, are able to participate for 2 years, and have no current or planned involvement in an organised exercise program.

The research study will include a thorough medical screening and education on peripheral artery disease, stress test, assessment of claudication severity, and other physiological measures. The study will be conducted at the University of Sydney Cumberland campus at Lidcombe and involves a minimum of 12 visits over a 24 month period. All participants will have their level of physical activity assessed and will have blood collected at 0, 4, 12 and 24 months.

Randomised Control Trial for childhood apraxia of speech

Do you have a child with Childhood Apraxia of Speech (CAS) / verbal dyspraxia? Children with CAS have speech difficulties which can impact on their literacy, social and academic skills.

Recent research studies have shown that there are different ways a Speech Pathologist can treat Childhood Apraxia of Speech. We want to compare two treatments in order to better understand why they work. This study will compare the Rapid Syllable Transitions (ReST) treatment and Ultrasound Biofeedback treatment.

Treatment for children with childhood apraxia of speech

Does your child have Apraxia?

Children with Childhood Apraxia of Speech (dyspraxia) have severe speech difficulties which often affect their literacy, social and academic skills. We want to improve treatment for these children. We want to know if a widely used treatment approach is effective in improving the speech of children with childhood apraxia of speech. What will you gain from participating in the study? You will receive a report on your child's assessment and 12 free sessions of speech therapy.

THELO study: Train High Eat Low for Osteoarthritis

Are you 40+ and living with knee osteoarthritis? You’re not alone - osteoarthritis affects two thirds of older Australians. Participate in the first study aimed at minimising the effects of, and prolonging life without knee osteoarthritis through targeted lifestyle intervention combining gait retraining, Progressive Resistance Training, and a low glycaemic index (GI) / high protein diet.

Research has shown that weight loss, increase muscle strength and minor changes to walking technique can reduce the amount of knee pain experienced by those with osteoarthritis. This study is looking at the best way to reduce knee pain and progression of osteoarthritis.

Researchers from the University of Sydney and Rheumatologists at Concord Repatriation General Hospital are looking for people aged 40 and older to join THELO Study. This free program includes a complete medical screening and functional assessment of your knee osteoarthritis. Activities are fully supervised by experience health professionals and will be conducted over 12 months at The University of Sydney, Faculty of Health Sciences, Lidcombe Campus.

If you would like to know more about this study or how to take part please contact Yareni Guerrero on 9351 9826.

Lower limb measurement study

We are seeking healthy men and women volunteers to have their arms and legs measured to determine what is a normal inter-limb circumference and volume difference.

A possible consequence of surgery when lymph nodes are removed or damaged is lymphoedema, which is a chronic and permanent swelling. With early detection, we are better able to manage and treat lymphoedema. Unfortunately it is currently unknown what an abnormal inter-limb difference is, making early detection more difficult.

Interested volunteers will have the arms and legs measured using a number of tools. Participation will take no more than 20 minutes.

If you would like to know more about the study, please contact or

What does it mean to be healthy?

Seeking: People aged 3-100 who consider themselves healthy for their age.
Participation requirement: A once-only assessment at the University of Sydney's Cumberland campus for 2-3 hours. The assessment includes performing basic physical assessments and completing questionnaires.
