AB  - Peak torque (PT), total work (TW) and acceleration time (AT) were measured during 
      isokinetic concentric and eccentric abduction of the shoulder in subjects with 
      subacromial impingement syndrome (SIS) and healthy subjects. The SIS group 
      consisted of 27 subjects (33.48 +/- 9.94 years) with unilateral SIS and it was 
      divided into two groups: (1) SIS with the dominant involved side, (2) SIS with 
      the nondominant involved side. The control group consisted of 23 healthy subjects 
      (32.26 +/- 9.04 years). PT, TW and AT were measured bilaterally at 60 and 180 
      degrees /s. No significant interactions were found between group and side (P > 
      0.05), as well as no significant main effects of group and side (P > 0.05) for 
      all variables during concentric abduction of the shoulder at both tested speeds. 
      During the eccentric contractions, lower TW (P < 0.05) was demonstrated by the 
      nondominant uninvolved side of SIS group at 60 degrees /s, and by the uninvolved 
      sides of the SIS groups at 180 degrees /s compared to the dominant side of the 
      controls. At 180 degrees /s, the nondominant uninvolved side of the SIS group 
      demonstrated slower AT (P < 0.05) compared to the dominant side of the control 
      group, as well as the nondominant involved side of the SIS group compared to the 
      nondominant side of the controls. The results showed no alterations in the 
      measured parameters during concentric and eccentric phases of isokinetic 
      abduction in subjects with SIS when compared to a control group. However, 
      alterations may be observed in the contralateral side during the eccentric phase 
      of abduction in subjects with unilateral conditions of SIS.
