Background: The aim of this study was to investigate the documentation for the effect of stretching exercises and strength training treatments of plantar fasciopathy. Methods: A literature review (MEDLINE, Embase and CINAHL) generated 282 separate articles (after adjusting for duplicates), out of which 11 studies (7 RCT´s and 4 systematic reviews) met the inclusion criteria. The results of the separate articles were qualitatively synthesized (stretching and strength training, and dosing variables). The PEDro scale was used for quality assessment. Results: 5 of the included RCT´s and 2 of the included systematic reviews evaluated the effect of stretching interventions, 2 RCT´s and 1 systematic review evaluated the effect of strengthening interventions, and one systematic review evaluated the effect of different dosing variables. The intervention period ranged from 1 week to 3 months. The data suggest that plantar fascia stretching (separately or in combination with Achilles stretching) and high load strength training, when applied over several weeks/months, may have positive benefits in regards to pain and function. It was not possible to identity to which extent outcome was related to differences in dosing variables. The PEDro-score ranged from 4 to 7 (out of 10). All the systematic reviews highlighted the need for further high quality research. Discussion: The present review suggests that stretching of the plantar fascia and high load strength training may have positive effects on pain and functioning. The heterogeneous nature and methodological weaknesses of the included studies limit the possibility to draw any absolute conclusions, and there is a need for new high quality studies.
