Dose-related effect of extracorporeal shock wave therapy for plantar fasciitis.

Lee SJ, Kang JH, Kim JY, Kim JH, Yoon SR, Jung KI - Ann Rehabil Med (2013)

Bottom Line: Significant VAS and RM score improvement, and PF thickness reduction were observed in both groups (p<0.01).After 3 sessions of ESWT, group M showed significant improvement in the VAS and RM score than group L, whereas after 3 additional sessions applied in group L, the main outcomes were no longer significantly different in both groups (p>0.05).Therapeutic effect might disclose a dose-related relationship; therefore, EFD and the times of the session are considerable factors when treating with ESWT.

ABSTRACT

Objective: To examine the dose-related effect of extracorporeal shock wave therapy (ESWT) for plantar fasciitis.

Methods: Sixty patients with plantar fasciitis despite conservative treatment were enrolled. The patients were divided into a low-energy group (group L: n=30, 1,000 shocks/session, energy flux density [EFD] per shock 0.08 mJ/mm(2)) and a medium-energy group (group M: n=30, 1,000 shocks/session, EFD 0.16 mJ/mm(2)). The main outcome measures were visual analogue scale (VAS), Roles and Maudsley (RM) score, and thickness of plantar fascia (PF). To compare the effects between each group, follow-up was carried out 1 week after 3 and 6 sessions, and 1 and 3 months after ESWT.

Results: Significant VAS and RM score improvement, and PF thickness reduction were observed in both groups (p<0.01). After 3 sessions of ESWT, group M showed significant improvement in the VAS and RM score than group L, whereas after 3 additional sessions applied in group L, the main outcomes were no longer significantly different in both groups (p>0.05).

Conclusion: Therapeutic effect might disclose a dose-related relationship; therefore, EFD and the times of the session are considerable factors when treating with ESWT.

Mentions: The subjects were placed into either a low-energy group (group L: n=30, 1,000 shocks/session, EFD per shock 0.08 mJ/mm2) or a medium-energy group (group M: n=30, 1,000 shocks/session, EFD per shock 0.16 mJ/mm2) through block randomization. All of the subjects received 3 sessions of ESWT at one-weekly intervals at differentiated energy levels according to their groups (group L3 and M3). In addition, the two groups were compared in terms of pain, function, and plantar fascia thickness. Afterward, group L3 received an additional 3 sessions of ESWT at one-weekly intervals, resulting in a total of 6 sessions of ESWT (group L6). Groups L6 and M3 were measured for pain, function, and plantar fascia thickness before ESWT, 1 week, 1 month, and 3 months after ESWT (Fig. 1).
