Spasticity Assessor

This app has been designed to provide allied health clinicians and medical practitioners with an accurate, user-friendly method of assessing lower limb spasticity in a clinical setting.

The app which is based on the principles of the Modified Tardieu scale enables you to assess spasticity of the gastrocnemius, soleus, hamstrings (at both 40° and 90° hip flexion) and quadriceps muscles. It is able to provide you with accurate values of joint range of motion (ROM) and speed of movement which are unable to be obtained using a traditional goniometer. It can also be used to provide real-time feedback ensuring consistency between clinicians and it can be used as a valuable teaching resource for students and inexperienced clinicians.

The use of this system to measure speed of movement and joint ROM has been validated in a group of 35 healthy controls and 35 individuals with a neurological condition. These studies involved comparing the concurrent validity of the Smartphone system to a criterion reference three-dimensional motion analysis (3DMA) system with excellent results. These studies included the completion of over 4,000 trials in total. Without further instrumentation, the app is not able to measure accurate start or end angles so if you usually measure either of these values with a goniometer as a part of your routine clinical practice then please continue to do so in conjunction with this system.
