Abstract EN
Patients with hemiplegia usually have weak muscle selectivity and usually perform strength at a secondary joint (secondary strength) during performing a strength at one joint (primary strength).
The abnormal strength pattern between shoulder and elbow joint has been analyzed by the maximum value while the performing process with strength changing from 0 to maximum then to 0 was a dynamic process.
The objective of this study was to develop a method to dynamically analyze the strength changing process.
Ten patients were asked to perform four group asks (maximum and 50% maximum voluntary strength in shoulder abduction, shoulder adduction, elbow flexion, and elbow extension).
Strength and activities from seven muscles were measured.
The changes of secondary strength had significant correlation with those of primary strength in all tasks (R>0.76, p<0.01).
The antagonistic muscles were moderately influenced by the primary strength (R>0.4, p<0.01).
Deltoid muscles, biceps brachii, triceps brachii, and brachioradialis had significant influences on the abnormal strength pattern (all p<0.01).
The dynamic method was proved to be efficient to analyze the different influences of muscles on the abnormal strength pattern.
The muscles, deltoid muscles, biceps brachii, triceps brachii, and brachioradialis, much influenced the stereotyped movement pattern between shoulder and elbow joint.
