Primary Outcome Measures :
  1. Change From Baseline in Forced Vital Capacity (FVC) [ Time Frame: Baseline, Week 6 ]
    Change from baseline in observed FVC. FVC is the maximum amount of air exhaled from the lungs after taking the deepest breath possible. Patients perform three to eight exhalations into a spirometer with the highest value recorded at Baseline and Week 6.

  2. Change From Baseline in Forced Expiratory Volume (FEV1) [ Time Frame: Baseline, Week 6 ]
    Change from baseline in observed FEV1 at one second. FEV1 is the maximum amount of air exhaled in one second. Patients perform three to eight exhalations into a spirometer with the highest value recorded at Baseline and Week 6.


Secondary Outcome Measures :
  1. Change From Baseline in FEV1/FVC Ratio [ Time Frame: Baseline, Week 6 ]
    Change from baseline in FEV1/FVC ratio. This ratio is calculated by dividing the FEV1 value by the FVC value. This represents that portion (or ratio) of FVC exhaled in one second.

  2. Change From Baseline in Ashworth Scale [ Time Frame: Baseline, Week 6 ]
    Change from Baseline in worst upper limb scores using the Ashworth Scale at Week 6 from Baseline. Upper limb includes finger, wrist, thumb, and elbow. Worst score was the highest value measured from the finger, wrist, thumb, or elbow at Baseline and Week 6 based on treated areas. The Ashworth Scale assesses the degree of muscle tone. It is a 5-point scale where 0 equals no increase in muscle tone and 4 equals very severe muscle rigidity. A low score indicates little or no stiffness. A high score indicates severe stiffness. A negative change from baseline score indicates improvement.
