Ann Rehabil Med 2016;40(5):871-877
To the Editor,
We found that the original version of this paper contains an error in the descriptions of Fig. 4 (page 875).
The correct descriptions of Fig. 4 are:
At the baseline, the HOOSs in groups A and B were 44.21±8.89 and 42.22±8.91, respectively. After 1 month, the HOOSs in each the respective groups were 53.56±8.77 and 51.05±8.72. After 3 months, were 56.86±6.44 and 54.36±5.31, and after 6 months, were 61.88±4.91 and 59.92±3.28.
The corrected Fig. 4 is shown below.
The Hip dysfunction and Osteoarthritis Outcome Score (HOOS) score at baseline and at 1-, 3-, and 6-month follow-ups after extracorporeal shock wave therapy in both groups. This figure shows significant improvement in the HOOS score in both groups, for entire period (*p<0.05 for time effect, *p<0.05 for group-time interaction). Group A, 0.12 mJ/mm2 energy group; group B, 0.32 mJ/mm2 energy group.
We apologize for any inconvenience this may have caused.
Yours sincerely,
Hoi-Sung Kee
