Conclusion :  Objective muscle strength assessment  can be reliably used in lower and upper extremities in post-stroke patients with chronic hemiparesis
Background : Muscle weakness is the main cause of motor impairment among stroke survivors and is associated with reduced peak muscle torque .
Objective : To systematic ally investigate and organize the evidence of the reliability of muscle strength evaluation measures in post-stroke survivors with chronic hemiparesis .
Trunk rotatory muscle performance in post-stroke hemiplegic patients.
This study was undertaken to determine whether the direction of trunk rotation would have any effect on trunk muscle performance of post-stroke hemiplegic patients . The design consisted of a nonr and omized control trial in a setting of secondary care ( rehabilitation unit at hospital facility ) . The subjects included 65 hemiplegic patients ( 50 males ) and age-matched 80 healthy controls ( 38 females ) .  Isokinetic trunk rotatory muscle performance at angular velocities of 60 , 120 , and 150 degrees per second was measured by using an isokinetic dynamometer ( Cybex Torso Rotation Unit ) . There were no significant differences in the peak torque and best work between the right and left directions of the trunk rotation in the hemiplegic patients or in healthy controls , regardless of the gender of the subjects ( paired t test , P > 0.05 ) . The muscle performance of the hemiplegic patients was significantly lower than that of the controls for both genders ( t test , P < 0.05 ) . In the hemiplegic patients , the direction of trunk rotation does not affect the trunk rotatory muscle performance , although the performance itself was slightly decreased
