Association of Ankle Dorsiflexion With Plantar Fasciitis

Leg length discrepancy is not a risk factor for plantar fasciitis

PURPOSE

Plantar fasciitis (PF) is a main source of heel pain, and only about one-third of patients have bilateral symptomatic involvement, although age, body mass index (BMI), and physical activities are known risk factors. The high prevalence of unilateral involvement is poorly understood. We aimed to assess the potential association between PF and the leg length discrepancy (LLD) in unilateral PF.

METHODS

A transversal case-control study was conducted from January 2019 to December 2020, including 120 participants allocated to two groups matched by BMI and sex: cases (with a diagnosis of PF; 50 ± 13 years) and control (without foot pain; 40 ± 15 years). For both groups, a difference greater than 0.64 cm in the scanometry determined the criteria for the presence of LLD.

RESULTS

The multivariate logistic regression analysis showed an independent association of PF only with age (p < 0.001), and no association with LLD. We did not observe differences in the mean discrepancy (1.37 ± 0.83 cm in the PF group in comparison with 1.13 ± 0.37 cm in the control group, [p > 0.05]) or in the prevalence of LLD between groups (48% [n = 29] in the PF group compared with 42% [n = 25] in the control group, [p > 0.05]). In the PF group, 80% of the participants reported unilateral pain. We observed a higher prevalence of pain in the shorter limb (p < 0.05).

CONCLUSION

Age was the only factor associated with the diagnosis of PF when groups were matched by sex and BMI. LLD was not an independent factor associated with the diagnosis of PF. However, when PF is unilateral, the shorter limb is more affected with 70% of prevalence.

Isolated Gastrocnemius Contraction and Gastroc Recession Surgery in Case of Planter Fasciitis: A Systemic Review and Meta-Analysis

Objective

The current systematic and meta-static review aimed to analyze the correlation between isolated gastrocnemius contracture and plantar fasciitis and the effectiveness of gastroc recession surgery in the treatment of plantar fasciitis.

Methodology

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to conduct this meta-analysis. A literature search was carried out on the following databases, including Google Scholar, PubMed, EMBASE, and the Cochrane databases with the appropriate medical subject headings (MeSH) to identify the eligible articles.

Results

A total of 13 studies were included in this meta-analysis. In this study, there is a significant difference in chronic plantar fasciitis outcome when comparing experimental and control (RR: 0.02; 95% CI: 0.01 to 0.05; P < 0.001; I2 = 29%). There is a significant difference in pain scale outcome when comparing pre-treatment and post-treatment (RR: 3.25; 95% CI 1.44 to 7.32; P = 0.004 < 0.01; I2 = 0%). A significant difference in VAS scale outcome when comparing pre-treatment and post-treatment (RR: 2.58; 95% CI 1.52 to 4.38; P = 0.0004 < 0.01; I2 = 0%).

Conclusion

In conclusion, the current systematic review and meta-analysis of gastrocnemius recession and proximal medial gastrocnemius release and other treatment measures for plantar fasciitis suggests that the improvement of ankle dorsiflexion, reduction in pain, and patient satisfaction are almost similar in all the treatment measures. Among the five treatment measures, gastrocnemius recession remains the best, followed by proximal medial gastrocnemius release.

A Multisegmental Approach to Dry Needling Plantar Fasciitis: A Case Study

CONTEXT

Plantar heel pain is a common problem affecting foot function, causing pain in the foot under the heel. Plantar fasciitis is commonly treated with conservative treatment, such as joint and soft tissue mobilization, self-stretching home programs, foot orthoses, and night splinting or booting. Dry needling (DN) has shown to be an effective method of treating plantar fasciitis (PF) in multiple randomized control trials. Dry needling is a technique that has been reported to be beneficial in managing pain and dysfunction after PF. Still, there is limited published literature on DN, a myofascial sequence as part of the treatment of PF.

CASE PRESENTATION

The patient was a 38-year-old female runner referred by a podiatrist for evaluation and treatment to include DN and therapy for persistent PF in the right foot. She was treated 4 times over 3 weeks with a home exercise program. Management and Outcomes: The DN intervention was beyond the local plantar fascia and incorporated 11 locations from the foot up the posterior chain and 2 electric stim channels. The patient had reduced pain as measured by a visual analog scale, increased function as measured by the functional ankle disability index, and range of motion increases.

CONCLUSIONS

This case illustrates the use of DN and a home exercise program to provide a favorable outcome in a patient with PF.
