Calf stretching and plantar fascia-specific stretching for plantar fasciitis: A systematic review and meta-analysis

BACKGROUND

Plantar fasciitis (PF) is the most common cause of heel pain. A calf stretching (CS) and a plantar fascia-specific stretching (PFSS) are two stretching techniques commonly administered by health care providers.

OBJECTIVE

To evaluate the literature on the application of these two stretching techniques in the treatment of PF and investigate their effectiveness and efficacy.

METHOD

A search of PubMed, Web of Sciences, PEDro, CINHAL and Scopus was conducted. Studies that applied stretching as a co-intervention were excluded. The risk of bias was assessed to determine the internal validity of the included trials. The GRADE approach was adopted to determine the overall quality. Pooled analysis was performed to determine the treatment effects of CS and PFSS in terms of the mean difference in the visual analog scale pain score.

RESULTS

Eight articles were found that represented randomized controlled trial and met the inclusion criteria. There was very low-quality evidence that the combined CS and PFSS was less effective in the short term than the other therapies. Comparison between CS and PFSS revealed moderate quality evidence for a larger effect of pain score reduction for PFSS treatment over CS, while very low-quality evidence supported that combined CS and PFSS or CS alone was superior to sham stretching.

CONCLUSION

There was moderate to very low-quality evidence of the effectiveness of stretching for PF. The treatment effect of stretching was large and comparable to other therapies. Future trials of higher quality are needed to clarify findings or to confirm findings.

Comparing the Role of Different Treatment Modalities for Plantar Fasciitis: A Double Blind Randomized Controlled Trial

INTRODUCTION

Although many treatment modalities including rest, stretching, strengthening, change of shoes, arch supports, orthotics, night splints and anti-inflammatory agents have been advocated for plantar fasciitis, there is no report in the literature which compares the independent effectiveness of each treatment modality without the concomitant use of any other one.

METHODS

A double blind, randomized controlled study was undertaken where 140 patients of plantar fasciitis were divided into four groups with 35 patients each. Patients in four groups received analgesics, hot water fomentation and silicon heel pads, plantar fascia stretching and calf stretching exercises, respectively. Heel pain was evaluated using Foot Function Index (FFI) and disability using Foot and Ankle Disability Index (FADI). Clinical evaluation was done weekly up to a period of 4 months and then at 6 months, 8 months, 10 months and 12 months.

RESULTS

Mean age of patients was 43.4 ± 10.6 years with average duration of symptoms being 27.26 weeks (range 4-200 weeks). Both FFI and FADI showed statistically significant improvement at 12 months in all the four groups (p value < 0.0001 for all groups). However, groups 2, 3 and 4 were observed to show statistically better results in terms of heel pain reduction (FFI) as compared to group 1 (ANOVA, p value < 0.0001 for group 1 vs. 2, group 1 vs. 3 and group 1 vs. 4). In terms of disability (FADI), best results were observed in group 3.

CONCLUSION

Plantar fascia stretching exercises resulted in most significant improvement in both the scores (FFI and FADI), followed by treatment with heat and silicone heel pad and calf stretching exercises.

The gastrocnemius: a new paradigm for the human foot and ankle

A silent gastrocnemius contracture can gradually do so much harm when left undetected and unattended. The calf is a common source of a majority of acquired, nontraumatic adult foot and ankle problems. When it comes to surgical lengthening procedures, whether at the Achilles, at the musculotendinous junction, or more proximal, the search must move on to find the safest, most accurate, and quickest recovery method possible. Addressing the calf contracture as definitive treatment and, better yet, as prevention will no doubt become a mainstay of the treatment of many foot and ankle problems.

The Role of Equinus in Flatfoot Deformity

Equinus plays an important role in flatfoot deformity. Proper evaluation and surgical management are critical to comprehensively treat and successfully resolved patients' symptoms. We have discussed the cause, evaluation, and some of the common surgical options. Each procedure has its inherent benefits and risks. It is imperative that the foot and ankle surgeon identify and include these procedures as part of the complete reconstructive surgery.
