AB  - Quantified assessment of spasticity is essential for the rehabilitation of persons with paralysis. We introduce the new SPAsticity Scale (SPAS), which we found highly correlated with the Modified Ashworth Score (MAS); yet, with a delicate gradation of spasticity compared to the MAS. The parameters defining the SPAS show the level and the type of spasticity (flexion or extension). The SPAS is based on a complex model of the pendulum type oscillations of the lower leg, which includes the spastic torques. The data to calculate SPAS were collected by a wearable instrument with two inertial measurement units and two EMG recording units in subjects with a complete chronic spinal cord injury.

AB  - Introduction: Cerebral palsy (CP) is often accompanied by motor limitations, abnormal movements and spasticity. Precise and reproducible assessment of spasticity is essential for the selection and follow up of the therapeutic protocol. In clinics the spasticity is most often characterized with the estimate of resistance to a manual flexion and extension of a particular joint and use of a modified Ashworth scale (MAS). The MAS grading depends on the subjective assessment by the examiner.
Aim: The possible alternative is to use the pendulum test (PT) determined parameters for the quantitative assessment of the spasticity.
Material and Methods: We used a new instrument from the company 3F - Fit Fabricando Faber comprising inertial measurement units at the shank and thigh, and two EMG recording units to record electromyographic signals from the hamstrings and quadriceps muscles. The study included 48 subjects diagnosed with cerebral palsy.
Results: The analysis of results showed that the new measure based on the PT recordings is highly corelated with the muscle tone in CP patients, and automatically distinguishes the type of spasticity (flexion or extension), relaxation rate and spasticity strength.
Conclusion: The new measure showed sensitivity of the PT and indicates great potential of using the PT in the protocols for better control of spasticity in CP patients.

AB  - Pendulum test is a method to quantify the spasticity. We used the goniogram recorded during the pendulum test to estimate the knee joint torque based on the model which considers spastic reflex activity. We fitted the exponential curve Th = ae-bt to the estimated knee joint torque to calculate the parameters a and b. We compared the scaled value log a/b with the modified Ashworth score. We used 8 sets of data collected in a clinical study with six complete paraplegic subjects. The comparison shows that the ratio a/b correlates with the MAS scores; thereby, can be used as a measure of spasticity. The advantage of using the ratio a/b is that this score is not rater dependent and that the scores are real numbers compared the MAS scores; thereby, providing better resolution of the level of spasticity.

AB  - Increased muscle tone and exaggerated tendon reflexes characterize most of the individuals after a spinal cord injury (SCI). We estimated seven parameters from the pendulum test and used them to compare with the Ashworth modified scale of spasticity grades in three populations (retrospective study) to assess their spasticity. Three ASIA B SCI patients who exercised on a stationary FES bicycle formed group F, six ASIA B SCI patients who received only conventional therapy were in the group C, and six healthy individuals constituted the group H. The parameters from the pendulum test were used to form a single measure, termed the PT score, for each subject. The pendulum test parameters show differences between the F and C groups, but not between the F and H groups, however, statistical significance was limited due to the small study size. Results show a small deviation from the mean for all parameters in the F group and substantial deviations from the mean for the parameters in the C group. PT scores show significant differences between the F and C groups and the C and H groups and no differences between the F and C groups. The correlation between the PT score and Ashworth score was 0.88. © 2017 IEEE.

AB  - The aim of this study was to determine changes in clinical and biomechanical measures of spasticity after administering galvanic vestibular stimulation in patients with a complete spinal cord injury (SCI). The spasticity in the lower limbs was assessed using the Modified Ashworth Scale and the pendulum test in seven SCI patients (grade A on the Asia Impairment Scale) before (0-), immediately after (0+), and at 5 and 30 min after the real versus sham galvanic vestibular stimulation (15 s each, anode over the right mastoid). Overall, the changes in spasticity were not significantly different between the real and sham galvanic vestibular stimulation. However, the Modified Ashworth Scale and the pendulum test indicated a reduction in spasticity in two out of seven patients. The results suggest that galvanic vestibular stimulation may modify spasticity in some patients with complete SCI, presumably through the residual vestibulospinal influences. Future studies should determine clinical and neurophysiological profiles of responders versus nonresponders and optimize parameters of galvanic vestibular stimulation. © 2018 Wolters Kluwer Health, Inc.

AB  - The pendulum test is the method for quantification of the level of spasticity in persons with spinal cord and brain injuries/diseases. The data for the assessment comes from the analysis of lower leg rotation in the sagittal plane while sitting caused by gravity. We built a simple instrument that uses the smart phone and passive markers for studying the pendulum movement of the leg. We compared the results of the new device with the results acquired with the conventional apparatus which uses a knee joint angle encoder and inertial sensors mounted on the upper and lower leg. The differences of parameters estimated from the test between the two systems are in the range of 5%, which is in the same range as the precision of the positioning of the pendulum apparatus on the leg. The new system is simple for the application (donning, doffing, setup time, accuracy, repeatability) and allows a straightforward interpretation to a clinician. © Serbian Journal of Electrical Engineering. 2018.

AB  - The assessment of spasticity is an important indicator of the course of the recovery in humans with central nervous system lesion. This recovery may be augmented by optimal ergonomic design of wheelchairs, beds, transferring devices and other devices used in activities of daily life. To quantify the influence of different aids and methods in reduction or increase of spasticity, an objective measure is required. The pendulum test was introduced to induce the stretch of the muscle, thereby, trigger spastic response, and the amplitudes of first sinusoidal movements are used as the measure of spasticity. We present a new model of the lower leg during the pendulum test which includes the nonlinear characteristics of the muscles, and a model of the shank and foot that are customized to the patient. The spastic torque component is calculated based on acquired values of angular acceleration, angular velocity, and angle. We developed a new analysis methodology and tool to describe the level and course of reflexive behavior. We describe the instrumentation for data acquisition. The kinematics is captured by two accelerometers, one gyroscope, and a Hall-effect joint angle encoder. Muscle activities of prime knee flexors and extensors are synchronously recorded. The simulation uses user's particular inertial parameters and data from repeated pendulum movements of the lower leg and outputs the reflexive torque. We developed the user-friendly software in MatLab for the analysis of data recorded with the new instrument. We present the application of the method in representative healthy subject and two spastic SCI patients. The main finding is that this method allows distinction between the flexion and extensions types of spasticity and the level of reflexive behavior.
