H to P1 H to P2 V to P2 H to R1 H to R2 V to R2 Movement Diagram Measurements H to L
Results - What Will We See? Agreement / Reliability repeat assessments Agreement / Reliability between PTs Correlation among MD measures Measures –End-feel category –MD: –Onset Pain / Resistance (H to P1, R1) –MD: –Maximum Pain and Resistance (H to P2, R2) –Limit of movement (H to L, i.e. ROM)
Before We See Results ICC: Reliability Coefficient Pearson r: Correlation Coefficient Both vary from 0 to 1 0 = no reliability / correlation 1 = perfect reliability / correlation Agreement: raw %, verbal descriptor for ‘k’
Reliability Results - I 1 st vs 2 nd Assessment Single PT feel same thing twice? When no true change?
Reliability Results - II PT A vs PT B Two PTs feel same thing once? When no true difference?
Correlation Results - I Onset Pain / Resistance vs H to L
Correlation Results - II Max Pain / Resistance vs H to L
Summary In Summary: Correlations with H to L on MD:.573 -.956 for H to P1, R1 (where we put ‘onset’ wrt ROM).914 -.999 for H to P2, R2 (where we put ‘max’ wrt ROM) Good agreement assigning end-feel categories: note: end-feel categories defined by end-range P/R Good reliability between 1 st & 2 nd assessments Good reliability between PTs, like having a 2 nd round
