Brief Summary:
This project will determine the feasibility and validity of measuring elbow muscle flexor stiffness in a population of patients with sub-acute severe acquired brain injury using two measurement methods, the portable spasticity assessment device (PSAD) (Movotec, Charlottenlund, Denmark) and an ultrasound measurement called shear wave sonoelastography (SWE).
Detailed Description:
The purpose of this study is to investigate the feasibility and validity of measuring hypertonia in the elbow flexors of patients with severe acquired brain injury in their sub-acute rehabilitation and collect data to determine the necessary size for a definitive study to determine the clinimetrics of the test methods. The long-term goal is to establish a valid and clinically feasible method for physiotherapists to quantify muscle tone in patients with neurological disorders.
The study hypotheses are:
1. SWE, PSAD and Modified Ashworth Scale (MAS) measurements can be obtained for elbow flexion hypertonia in all patients (no missing data due to test procedure),
2. SWE and PSAD have a moderate to good intra-day intra-tester reliability (ICC two-way mixed effects model with absolute agreement. ICC\>0.5, Bland Altman)
3. Passive muscle stiffness measured using the PSAD and SWE have a fair concurrent validity with MAS (Spearmans correlation \>0.3)
4. SWE and PSAD are responsive in measuring a reduction of the effect of routine clinical treatment of the hypertonic muscles with botulinum toxin type A (BTX-A) (paired T-test or Wilcoxon test, p\>0.05)
