About

Although there are many conservative method for plantar fasciitis, patients might spend 2 years to achieve resolution. Recent study have shown that pulsed radiofrequency (PRF) lesioning of peripheral nerve can alleviate kinds of pain condition. However there are no studies of PRF lesioning of the tibial nerve in patients with plantar fascilitis by using ultrasound-guided (UG) techniques.

Full description

Patients with unilateral plantar Fasciitis will be enrolled and randomized into intervention and control group. One dose of sono-guided PRF is applied in the intervention group and xylocaine in control group. Outcome measurements included visual analog scale (VAS)、foot health status questionnaire and the thickness of plantar fascile measured by musculoskeletal ultrasonography at different follow-up frame (4th week, 2nd month, 3rd month after treatment).

Enrollment: 36 patients

Sex: All

Ages: 20+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Heel pain more than 3 months
• Age more than 20 year-old
• The increased thickness of plantar fascile (>4mm) measured by sonography
• Must be conscious
• Not receive steroid or other injection in plantar fascile in past 6 months

Exclusion criteria

• Cancer of any site

Masking: Double Blind

---

36 participants in 2 patient groups, including a placebo group

pulsed mode radiofrequency

Active Comparator group

Description:

Pulsed radiofrequency (PRF) treatment, a relative novel pain intervention at recent decade, was found to be able to alleviate pain by delivering an electrical field and heat bursts at a temperature less than 42°C to neural tissue in the absence of neural injury. One dose of PRF was given in tibial nerve behine the medial ankle in intervention group.

Treatment:

Device: Pulsed radiofrequency (PRF)

Xylocaine

Placebo Comparator group

Description:

2 c.c xylocaine was given in tibial nerve behind the medial ankle in control group.

Treatment:

Drug: Xylocaine
