What is Aussie current?
Aussie current, also known as Australian current, is a therapeutic alternating electrical current with frequency in the range of KHz with some similarity with interferential current and Russian current. The difference is in the carrier frequency of the KHz current used, in the duration of bursts and in the waveform. Traditionally, Interferential current is modulated in amplitude in sinusoidal form and the Russian current is formed from bursts with 50% duty cycle (on and off).
Aussie current presents short duration burst, which means that the stimulation promoted by Aussie current is more effective in comparison to other therapeutic currents.
Research and development of the current
Initial research regarding the scientific development of Aussie current were conducted by Australian researcher and PhD professor PhD Alex Ward, from the La Trobe University, in Melbourne, Australia, and had its beginnings in 1998. The inquiry of Dr. Ward, at the time, was related to the therapeutic values used in other therapeutic electrical currents already in existence, such as Functional Electrical Stimulation (FES), Russian, Interferential and TENS, for motor and sensory stimulation.
Were the parameters offered by Russian and FES currents the most adequate to promote motor stimulation in the most efficient manner, with more production of torque, less discomfort and less muscle fatigue? In relation to sensory stimulation, were the parameters offered by different forms of TENS and Interferential currents the ideal ones regarding the level of discomfort during the stimulation?
Thus, Dr. Ward began, alongside with his colleagues, a series of scientific studies combining different parameters, such as: carrier frequency, forms of modulation of electric currents and duty cycles, and comparing these parameters with already existing currents. One of the first publications, titled “Sensory, motor and pain thresholds for stimulation with mediun frequency alternating current” (Arch. Phys. Med. Rehabil. 79, 273-279, 1998), suggests that for less discomfort during electrostimulation procedure, greater alternating frequencies are more desirable.
Published in 2009, by Alex Ward and his colleagues, “Comparison of the analgesic efficacy of medium-frequency alternating current and TENS”, in the publication Physiotherapy (Dec.; 95(4): 280-288, 2009), concludes that Aussie current is as effective as TENS in the increase of the pain threshold in healthy individuals *.
Alex Ward, MSc, PhD, is associate professor at La Trobe University, in Melbourne, Australia. he is a Bachelor in Science of Physics from The University of Sydney and Master in Biophysics from the Macquarie University before lecturing Science of Health at The University of Sydney.
After many years as a lecturer in Health Sciences, Dr. Ward started his research about the electrophysical agents used in physiotherapy. Dr. Ward finished his doctorate from the La Trobe where he is currently a Professor and Researcher.
He has published over 30 manuscripts revised by peers in the field of electrophysical agents, besides several books, including “Electricity, Fields and Waves in Therapy” – in its third edition by Science Press), and is a co-author of “Electrotherapy Explained” – in its fourth edition by Elsevier, published in Portuguese, Korean, Polish and Greek translations. His research includes the use of electrotherapeutic waveforms, physiology of the nerve and muscle and the effects of electrical stimulation in the central nervous system.
he is a member of the Editorial Board of the international publication “Archives of Physical Medicine and Rehabilitation” and is currently a reviewer for the publications “Physiotherapy Theory and Practice” (UK). he is also a well-known founding member of the International Society for Electrophysical Physiotherapy Agents (ISEPA), and has been recently acknowledged by the World Confederation for Physical Therapy (WCPT). Dr. Ward lives with his family in Melbourne, Australia, and is a consultant for physiotherapists, both locally and internationally.
Investment in innovation
The history of Aussie current in Brazil and in the world began in 2007, when we followed the studies and researches carried out by Dr. Alex Ward very closely. At each publication, Dr. Ward showed that he was about to present something different, regarding electric stimulation, based on the results of his studies.
As we contacted Dr. Ward, there was confirmation by the researcher that his objective, resulting from a series of scientific studies, was to create a new proposition for motor and sensory stimulation, which was named Aussie current.
In November, 2007, our CEO, Mr. José Ricardo de Souza, traveled to Australia to meet with Dr. Ward.
The idea was to incorporate, in our line of products for physical rehabilitation, an exclusive electrotherapeutic modality with great therapeutic potential and fundamentally based on scientific research, published in the physical rehabilitation field of study.
Our first device to receive Aussie current as a therapeutic modality was Heccus. After that, Aussie current was included in Neurodyn 10 Channels, Neurodyn Rubi and now we present to the sports physiotherapists Neurodyn Aussie Sport.
Positioning of the electrodes
Pathologies – Spine
Mechanism: more common in T11-L2, can be related to trauma or osteoporosis;
Signs and symptoms: acute pain with contracture of the adjacent muscle and extension and rotation limitation.
Mechanism: degenerative alterations which generally affect C5-C6, C6-C7, L4-L5 in individuals over 60 years of age;
Signs and symptoms: slow evolution, unilateral pain which increases with prolonged postures, increase of pain with extension and decrease with flexion without irradiation, diagnosis confirmed by X-ray with the presence of osteophytes, decrease of the articular space and narrowing of the intervertebral foramen.
Mechanism: traumatic fracture of pars or stress fracture due to repeated or sustained extension, pathology found in young athletes, secondary to repetition trauma (ski jumping or gymnastics). There might be structural predisposition;
Signs and symptoms: pain, primarily with extension, intermittent neurological signs and symptoms. Oblique X-ray reveals fracture of pars interarticularis without sliding.
Mechanism: vertebral subluxation or secondary sliding to long-term lumbar trauma. Retrolisthesis = is an uncommon dysfunction, which presents flexion symptoms;
Signs and symptoms: compromising of the L5 sciatic nerve, morning rigidity, difficulty in rising from bed, increase of pain with trunk extension, poor neuromuscular control (process in 2 phases to move from previous flexion to extension. First, extending the lumbar spine and then extending the hip) and deformity in palpable degree only in the orthostatic position.
Positive Compression and passive intervertebral movement tests and X-ray in AP and lateral confirm the diagnosis.
Lumbar Disc Pathology
Mechanism: generally, it results from repetition stress in the lumbar spine through inadequate body movements or excessive posterior/lateral > lateral force; more common between 30 and 50 years of age. See below in “Posture and pain in lumbar disc pathologies”;
Signs and symptoms:
- Postero-lateral disc herniation: the first sign is lumbalgia (which slowly decreases, and there is also decrease in leg pain), decrease in flexion of secondary lumbar spine and increase of pressure over the disc, positive thecal signs (pain when sneezing or coughing), positive straight leg raise test, decrease of lumbar lordosis and lateral deviation of the foot which decreases in lying position;
- Lateral disc herniation: absence of lumbalgia, symptoms in lower limbs consistent with the level of the lesion, increase of pain in standing position and walking, decrease of pain in sitting position and negative straight leg raise test. The standard X-ray is of little consequence, because it only detects pre-existing degenerative alterations; MRI, CT, myelogram and discogram are used for the diagnosis.
Posture and pain in lumbar disc pathologies
Posture: Ipsilateral Tilt (medial pain attitude)
- Pain – Herniation is medial to the nerve root – decrease of pain;
- Pain – Herniation is lateral to the nerve root – increase of pain.
Posture: Contralateral Tilt (lateral pain attitude)
- Pain – Herniation is medial to the nerve root – increase of pain;
- Pain – Herniation is lateral to the nerve root – decrease of pain.

An X-ray is carried out if in case of suspected fracture. Reduction maneuver: thumb in the cubital fossa to serve as a fulcrum support and execute the supination and flexion of the forearm.
Distension of the medial collateral ligament
Mechanism: straining or rupture of the ligament, common in shot put athletes, secondary to valgus stress;
Signs and symptoms: acute trauma which can be accompanied by a pop, pain during palpation of the medial articular line and valgus instability. Diagnosis confirmed by MRI. It is necessary to rule out avulsion.

An X-ray can rule out fracture, tumor, loose bone fragments. MRI can reveal pseudo-rupture. The diagnosis is confirmed with arthrography with contrast.
Articular Degenerative disease (arthrosis)
Mechanism: resulting from ageing, alteration of biomechanics, sequelae of trauma or articular pathology, repetitive trauma;
Signs and symptoms: crepitation in the articular line, reduction of the terminal extension of the knee secondary to edema (atrophy of the femoral quadriceps), reduction of the stop time in gait. “Gelling phenomenon”: increase of viscosity of the synovial fluid secondary to inflammation. Pain in the anteromedial knee and rigidity with immobilization. X-ray reveals narrowing of the articular space, spurs and osteophytes.

Posture: shoulder in medial rotation and slightly adducted, elbow in flexion, forearm in pronation and upper limb sustained by collateral limb. Acute stabbing pain, muscle contracture, humeral head is palpable in anterior/posterior armpit; positive apprehension and sulcus sign test. X-ray: lesion de Hills-Sachs lesion is visible in the incidence A/P with the upper limb in lateral rotation. The A Bankart lesion is visible in the Garth incidence (apical oblique) and it is necessary to rule out fracture of neck of the humerus in elderly individuals.
Mechanism: chronic irritation resulting from trauma or awkward movements. The anteriorized head contributes for the abnormal scapulohumeral rhythm;
Signs and symptoms: the pain increases at night. Pain in palpation localized in the biceps tendon at 10° of medial rotation (positions the tendon anterior and approximately 6cm below the acromion. The active elevation results in a painful arch, crepitation, positive Speed test, Yergason’s test negative for pop but painful. X-ray incidence over the bicipital sulcus reveals the angle of the medial wall, spurs and degenerative alterations. Caudal incidence reveals spurs, frequently associated with impact of the rotator cuff.

Pathologies – Ankle and foot
Hallux Valgus (Bunions)
Mechanism: rheumatoid arthritis, inadequate shoes and flat feet;
Signs and symptoms: pain, edema, hallux valgus > 15°. Hallux and second toe in mallet. X-ray is useful and it is necessary to rule out rheumatoid arthritis.
Mechanism: the plantar fascia is a continuous structure with the gastrocnemius muscle subjected to inflammation secondary to repetitive stress, caused by inadequate shoes, hard surfaces, increase in pronation and obesity;
Signs and symptoms: morning pain that decreases with exercise, nodules are palpable over the proximal medial border of the plantar fascia, pain in dorsiflexion and extension of the toes, decrease in dorsiflexion due to the shortening of the gastrocnemius, weakness in the intrinsic muscles of the foot, sensitivity and normal reflex and normal electroneuromyography. X-ray may reveal calcaneal spur, however there is no correlation between a bone spur and the plantar fasciitis pain.
Mechanism: structurally, there are three anatomic sheaths where the tendon passes in an acute angle which may result in irritation or decrease in vascularization secondary to trauma, inversion sprain or direct contusion;
Signs and symptoms: subluxation of the tendon (clamping in the eversion in dorsiflexion) the subluxation is the most common in young athletes, secondary to forced dorsiflexion of the inverted foot with contraction of the fibular, as well as edema and ecchymosis in the inferior region of the lateral malleolus. An X-ray may reveal avulsion of the lateral retinaculum.
Sever’s disease (calcaneal apophysitis)

Signs and symptoms: popping sound associated to the lesion. palpable, hatchet-shaped deformity in the tendon (Hatchet sign) if examined prematurely, impossibility of walking on the tip of the toe, edema (within 1 to 2 hours) and ecchymosis, positive Thompson test. MRI confirm the diagnosis.
Mechanism: lesion of the anterior/posterior inferior tibiofibular ligament secondary to hyper dorsiflexion or eversion;
Signs and symptoms: positive compression and lateral rotation tests, pain and edema over the ligaments and interosseous membrane. Oblique X-ray may show abnormal widening of the articular space. Recovery time: 5 + (0.97 x cm from the ankle articulation, in which the Compression test is positive) of approximately three days.
Mechanism: lesion of the anterior talofibular and posterior talofibular ligaments, secondary to inversion with plantar flexion;
