Author (Year) Pressure Frequency Impulses Session Main findings
Konjen et al., (2015) 2 bar 10 Hz 2,000 impulses 6 sessions Pain (VAS): both improved; rESWT > US (p<0.001). Function (PFPS mobility): rESWT better (p<0.001). Satisfaction: 80% vs 33% (p=0.025).
Rompe et al. (2015) 4 bar 8 Hz 2,000 impulses 3 sessions At 2-4 mos: rESWT+stretching > rESWT alone for FFI and satisfaction (p<0.001). At 24 mos: no between-group difference.
Eslamian et al. (2016) 0.2 mJ/mm2 2 Hz 2,000 impulses 5 sessions Both groups improved (VAS/FFI, p<0.001). Between-group difference not significant (FFI at 8 w, p=0.072); ESWT showed higher satisfaction/success trend.
Hocaoglu et al. (2017) 0.16 mJ/mm2 10 Hz 2,000 impulses 3 sessions Pain: steroid showed faster early relief, but rESWT effects were more sustained to 6 mos; plantar fascia thickness decreased in both groups.
Ibrahim et al. (2017) 3.5 bar 8 Hz 2,000 impulses 2 sessions rESWT > placebo for pain and Roles & Maudsley score across follow-ups (p<0.001); benefits maintained at 24 mos.
Ulusoy et al. (2017) 2.5 bar 10 Hz 2,000 impulses 3 sessions All groups improved (VAS/AOFAS/HTI, p<0.001). LLLT and ESWT were similar; both outperformed ultrasound for function and response rates.
Yin et al.(2017) 0.2, 0.4, 0.6 (respectively) mJ/mm2 8 Hz 2,400 impulses 3 sessions Success rate: 66.9%. Predictors of response included baseline VAS, edema, and heel spur; model accuracy 89.6%.
Uğurlar et al. (2018) 4 bar 6 Hz 2,000 impulses 3 sessions Pain: CSI best short-term (1 mos), ESWT best mid-term (3-6 mos). At 36 mos, no differences among treatments (effects not sustained).
Morral Fernández et al. (2019) 2.0 bar 8 Hz 2,500 impulses 3 sessions Device appearance had no effect. All groups improved over time; no between-group differences in VAS, FFI, or plantar fascia thickness.
Asheghan et al. (2021) 2 bar 10 Hz 2,000 impulses 3 sessions Pain (VAS): both improved with no between-group difference. Function: ESWT improved FAAM-Sport more than prolotherapy (p=0.038).
Mohammed et al. (2022) 0.2 mJ/mm2 2 Hz 2,000 impulses 6 sessions Early follow-up showed no clear between-group difference; at 6 mos, the comparator (steroid injection) showed greater pain reduction (p<0.05).
Wheeler et al. (2022) 2.4 bar 10 Hz 2,000 impulses 3 sessions Dose comparison: no between-group differences at any time point. Both groups improved; no superiority of the 'recommended' vs 'minimal' protocol.
Moneim et al. (2023) 2.5 bar 10.0 Hz 2,000 impulses 4 sessions Both groups improved; ESWT produced greater pain reduction at 12 wks (p=0.004). Thickness decreased in both; CSI+TUS reduced thickness more at 4 wks, but not at 12 wks.
Orhan et al. (2023) 3 bar 6 Hz 2,000 impulses 4 sessions 6 wks: CSI provided the greatest early pain relief. 3-6 mos: ESWT showed superior longer-term improvement (pain and AOFAS) compared with CSI/KT.
On & Yim (2023) 3 bar 9 Hz 2,000 impulses 10 sessions Both improved. Adding local vibration to ESWT improved pain (NRS) and plantar fascia thickness more than ESWT alone (p<0.05); FFI not different.
RIAZ et al.(2023) 1.4 bar 10 Hz 2,000 impulses 2 sessions All groups improved over time; between-group differences for pain/function were not statistically significant at follow-up.
Pabón-Carrasco et al. (2024) 0.20 mJ/mm2 5 Hz 2,000 impulses 3 sessions Early: rESWT had lower pain at 3 wks (p≤0.0001). By 5 wks, both groups reached pain remission. rESWT showed greater fascia-thickness reduction and higher PGIC/EQ-5D.
Wang et al.(2024) 2.0 bar 10 Hz 2,000 impulses 3 sessions Both improved (p<0.001). rESWT+Trps showed greater NRS reduction and heel temperature decrease at 12 wks.
Ines et al.(2025) 2.0 bar 10 Hz 2,000 impulses 2 sessions Both groups improved; no between-group differences in VAS or FFI. ESWT showed greater heel temperature reduction; success rate difference was not significant.
