Effects of therapeutic interventions on pain due to plantar fasciitis: A systematic review and meta-analysis

OBJECTIVE

To determine the effects of different therapeutic interventions that have ever been evaluated in randomized controlled trials on pain due to plantar fasciitis.

METHODS

We searched different electronic databases until September 2022. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the overall certainty evidence.

RESULTS

A total of 236 studies met the study criteria, including 15,401 patients. Botulinum toxin MD -2.14 (CI: -4.15, -0.14), micronized dehydrated human amnion/chorion membrane injection MD -3.31 (CI: -5.54, -1.08), dry needling MD -2.34 (CI: -4.64, -0.04), low-dye taping MD -3.60 (CI: -4.16, -3.03), low-level laser therapy MD -2.09 (CI: -2.28, -1.90), myofascial releases MD -1.79 (CI: -2.63, -0.94), platelet-rich plasma MD -2.40 (CI: -4.16, -0.63), radiofrequency MD -2.47 (CI: -4.65, -0.29), and stretching MD -1.14 (CI: -2.02, -0.26) resulted in being effective treatments for pain when compared to the control in the short term. In the medium and long term, only extracorporeal shock wave therapy MD -0.97 (CI: -1.13, -0.81)/MD -2.49 (CI: -3.17, -1.82) was effective for improving pain when compared to the control.

CONCLUSIONS

Considering the available studies, this systematic review and meta-analysis showed that different therapeutic interventions seem to be useful strategies for improving pain in patients with plantar fasciitis. In the medium and long term, only extracorporeal shock wave therapy was effective in improving pain when compared to the control.

Artificial Intelligence Technology Combined with Ultrasound-Guided Needle Knife Interventional Treatment of PF: Improvement of Pain, Fascia Thickness, and Ankle-Foot Function in Patients

Objective

To explore the effect of artificial intelligence (AI) technology combined with ultrasound-guided needle knife intervention in the treatment of plantar fasciitis (PF) on pain, fascia thickness, and ankle and foot function.

Methods

A total of 130 patients with PF treated in our hospital from January 2019 to April 2021 were enrolled. The patients were randomly assigned into the control group and the study group. The control group received ultrasound-guided needle knife interventional therapy, and the study group received AI technology combined with ultrasound-guided needle knife interventional therapy. The curative effect, VAS score, plantar fascia thickness, plantar fascia elasticity score, plantar fascia blood flow index, and AOFAS score were investigated.

Results

The total effective rate of the study group was higher compared to that of the control (P < 0.05). There exhibited no significant difference in VAS score before treatment, but the VAS score of the study group was lower compared to that of the control group at 2, 4, and 8 weeks after treatment. There exhibited no significant difference in plantar fascia thickness before treatment (P > 0.05), but after treatment, the plantar fascia thickness in the study group was lower compared to that in the control (P < 0.05). The plantar fascia thickness in the study group was lower compared to that in the control at 2, 4, and 8 weeks after treatment (P < 0.05). In terms of the plantar fascia elasticity score, there exhibited no significant difference before treatment (P > 0.05), but the plantar fascia elasticity score of the study group was lower compared to that of the control at 2, 4, and 8 weeks after treatment (P < 0.05). There exhibited no significant difference in plantar fascia blood flow index before treatment (P > 0.05), but after treatment, the plantar fascia blood flow index in the study group was higher compared to that in the control (P < 0.05). The plantar fascia blood flow index in the study group was higher compared to that in the control at 2, 4, and 8 weeks after treatment (P < 0.05). There exhibited no significant difference in the AOFAS score before treatment, but after treatment, the AOFAS score of the study group was higher compared to that of the control at 2, 4, and 8 weeks after treatment.

Conclusion

Patients with PF receive AI technology combined with ultrasound-guided needle knife interventional therapy, which can effectively relieve pain and improve fascia thickness and ankle-foot function. Thus, AI technology combined with ultrasound-guided needle knife interventional therapy has the advantages of convenient operation, safety, and effectiveness, which is worthy of clinical application.

Myofascial Treatment Techniques on the Plantar Surface Influence Functional Performance in the Dorsal Kinetic Chain

Prior studies have shown that self- and manual massage (SMM) increases flexibility in non-adjacent body areas. It is unclear whether this also influences performance in terms of force generation. Therefore, this study investigated the effect of SMM on the plantar surface on performance in the dorsal kinetic chain. Seventeen young participants took part in this within-subject non-randomized controlled study. SMM was applied on the plantar surface of the dominant leg, but not on the non-dominant leg. A functional performance test of the dorsal kinetic chain, the Bunkie Test, was conducted before and after the intervention. We measured the performance in seconds for the so-called posterior power line (PPL) and the posterior stabilizing line (PSL). The performance of the dominant leg in the Bunkie Test decreased significantly by 17.2% from (mean ± SD) 33.1 ± 9.9 s to 27.4 ± 11.1 s for the PPL and by 16.3% from 27.6 ± 9.8 s to 23.1 ± 11.7 s for the PSL. This is in contrast to the non-dominant leg where performance increased significantly by 5.1% from 29.7 ± 9.6 s to 31.1 ± 8.9 s for the PPL and by 3.1% from 25.7 ± 1.5 s to 26.5 ± 1.7 s for the PSL. SMM interventions on the plantar surface might influence the performance in the dorsal kinetic chain.

Elasticity of the Achilles Tendon in Individuals With and Without Plantar Fasciitis: A Shear Wave Elastography Study

The elastic properties of the Achilles tendon (AT) are altered in local injury or other diseases and in response to changes in mechanical load. Recently, elastography has been used to evaluate variations in tendon elastic properties, mainly among healthy individuals or athletes. Therefore, this study evaluated the biomechanical changes in ATs in individuals with and without plantar fasciitis (PF). The purposes were as follows: (1) to evaluate the passive stiffness of three regions of the AT which defined as 0 (AT0 cm), 3 (AT3 cm), and 6 cm (AT6 cm) above the calcaneal tuberosity in participants with and without PF, (2) to investigate the interplay between the passive stiffness in patients with PF and pain, (3) to detect optimal cut-off points of stiffness of the AT in assessing individuals with chronic PF, and (4) to determine the correlation between the plantar fascia thickness (PFT) and pain. This cross-sectional study included 40 participants (mean age = 51 ± 13 years). When the ankle was in a relaxed position, patients with PF experienced increased passive stiffness in AT0 cm (p = 0.006) and AT3 cm (P = 0.003), but not in the neutral position. Significant correlations were observed between pain and stiffness of AT (AT0 cm r = 0.489, P = 0.029; AT3 cm r = 487, P = 0.030; AT6 cm r = 0.471, P = 0.036), but not in the PFT (P = 0.557). Optimal cut-off stiffness was AT (452 kPa) in the relaxed ankle position. The plantar fascia of patients with PF was significantly thicker than that of the controls (P < 0.001). Findings from the present study demonstrate that tendon stiffness is a good indicator of the clinical situation of patients with PF. Monitoring passive tendon stiffness may provide additional information to assess severity of the condition and guide therapeutic. The treatment programs for PF should also be tailored to the distal AT, as conventional therapy might not be targeted to tight tendons.

The Effects of Taping Combined with Wrist Stabilization Exercise on Pain, Disability, and Quality of Life in Postpartum Women with Wrist Pain: A Randomized Controlled Pilot Study

The purpose of this study was to evaluate the effects of wrist stabilization exercise combined with taping on wrist pain, disability, and quality of life in postpartum women with wrist pain. Forty-five patients with wrist pain were recruited and randomly divided into three groups: wrist stabilization exercise + taping therapy (WSE + TT) group (n = 15), wrist stabilization exercise (WSE) group (n = 15), and control group (n = 15). The WSE + TT and WSE groups performed wrist stabilization exercises for 40 min (once a day, five times a week for eight weeks), and the control group performed passive range of motion (P-ROM) exercise for the same amount of time. Additionally, the WSE + TT group attached taping to the wrist and forearm during the training period. The visual analogue scale (VAS) was used to assess pain level of the wrist. The Disabilities of the Arm, Shoulder and Hand (DASH) and the Short Form-36 (SF-36) were used to evaluate the degree of wrist disability and quality of life, respectively. The WSE + TT group showed a significant decrease in wrist pain and functional disability compared to two groups (p < 0.05). Significant improvement in the SF-36 score was observed in the WSE + TT and WSE groups compared to that in the control group (p < 0.05). However, there was no significant difference between the WSE + TT and WSE groups in the SF-36. Our findings indicate that wrist stabilization exercise combined with taping is beneficial and effective in managing wrist pain and disability in postpartum women with wrist pain.
