The pathomechanics of plantar fasciitis.

Plantar fasciitis is a musculoskeletal disorder primarily affecting the fascial enthesis. Although poorly understood, the development of plantar fasciitis is thought to have a mechanical origin. In particular, pes planus foot types and lower-limb biomechanics that result in a lowered medial longitudinal arch are thought to create excessive tensile strain within the fascia, producing microscopic tears and chronic inflammation. However, contrary to clinical doctrine, histological evidence does not support this concept, with inflammation rarely observed in chronic plantar fasciitis. Similarly, scientific support for the role of arch mechanics in the development of plantar fasciitis is equivocal, despite an abundance of anecdotal evidence indicating a causal link between arch function and heel pain. This may, in part, reflect the difficulty in measuring arch mechanics in vivo. However, it may also indicate that tensile failure is not a predominant feature in the pathomechanics of plantar fasciitis. Alternative mechanisms including 'stress-shielding', vascular and metabolic disturbances, the formation of free radicals, hyperthermia and genetic factors have also been linked to degenerative change in connective tissues. Further research is needed to ascertain the importance of such factors in the development of plantar fasciitis.

The efficacy of a pneumatic compression device in the treatment of plantar fasciitis.

Plantar fasciitis is a common foot disorder that affects more than two million Americans each year. Conservative management of plantar fasciitis is the first line of treatment by the medical specialist who frequently encounters this common foot complaint. In this study, 50 patients with plantar fasciitis of 4 weeks duration but less than 12 weeks were randomized into two groups. One group of 25 patients used the AirHeel (Aircast, Inc.) and the second group of 25 used the 1st Step prefabricated foot insert (Wrymark, Inc). Standardized weight-bearing radiographs were obtained in order to categorize the foot type: normal arch, pes planus, or pes cavus. Patients were initially evaluated and at 12 weeks they returned for a subsequent visit. The contact area of the foot with the AirHeel and 1st Step insert were similar, an increase of 27% and 26%, respectively, over the contact area barefoot. There was a noted difference in force reduction with the two devices. The AirHeel reduced the midstance force by 20.19%, as compared to the 1st Step insert which showed a 1.03% increase in midstance force. Patients with a higher initial pain score seemed to respond better initially to the AirHeel (p = 0.015) than the 1st Step insert (p = 0.035). This study demonstrates the benefits of offloading the foot at midstance with two devices to relieve the discomfort associated with plantar fasciitis. The Aircast AirHeel is a new modality for dynamic, functional treatment of proximal plantar fasciitis.

A biomechanical approach to the prevention, treatment and rehabilitation of plantar fasciitis.

Plantar fasciitis is a repetitive microtrauma overload injury of the attachment of the plantar fascia at the inferior aspect of the calcaneus. The diagnosis of plantar fasciitis is common among athletes in many sports, primarily those sports that involve running. Common treatments for plantar fasciitis, including ice, stretching, ultrasound, and shoe inserts are helpful in reducing the symptoms. However, recurrence of the problem is common. By understanding the potential biomechanical causes of this disorder it may be possible to correct the anatomical and biomechanical variables that cause plantar fasciitis and reduce the rate of recurrence as well as speed the rehabilitation process. It may also be possible to identify predisposing maladaptations that can be corrected, therefore, preventing the initial occurrence of plantar fasciitis.

Critical differences in lateral X-rays with and without a diagnosis of plantar fasciitis.

Plantar fasciitis is a clinical diagnosis and is often combined with some form of imaging to validate the diagnosis. The clinical utility of lateral X-rays lies in the fact that they are relatively inexpensive and may contribute to ruling out other osseous causes of pain. In this study 106 (27 plantar fasciitis (PF) and 79 controls) plain non-weight bearing lateral X-rays were examined by a blind examiner to document the key features of the lateral X-ray between images of individuals with and without plantar fasciitis. As expected calcaneal spurs were observed in both groups (85% PF and 46% controls). However, plantar fascia thickness and fat pad abnormalities resulted in the best group differentiation (p<0.0001) with sensitivity of 85% and specificity of 95% for plantar fasciitis. It was concluded that the key radiological features that differentiate the groups were not spurs but rather changes in the soft tissues. If it is deemed necessary to confirm the diagnosis of typical plantar fasciitis with imaging, a lateral non-weight bearing X-ray should be the first choice investigation especially if these key features are noted.

Functional biomechanical deficits in running athletes with plantar fasciitis.

Plantar fasciitis is a relatively common injury that occurs in running athletes. The disease entity is a good example of an overloaded process of the plantar fascia at its calcaneal insertion. This study was designed to examine the strength and flexibility findings in the muscles that are put on tensile load during running, and which are responsible for controlling the forces on the foot during stance and pushoff, thus modifying the overload. Three groups of athletes underwent physical examination, including checking ankle range of motion in plantar flexion and dorsiflexion. Cybex peak torque measurements were taken at 60 and 180 deg/sec. The groups were a control group of 45 athletes with no symptoms, a group that included 43 affected feet with symptomatic plantar fasciitis, and a group that included the 43 unaffected contralateral feet. Analysis of data showed dynamic range of motion deficits in 38 of 43 affected feet, static range of motion deficits in 37 of 43 affected feet, deficits in peak torque at 60 deg/sec in 41 of 43 affected feet, and deficits in peak torque at 180 deg/sec in 37 of 43 affected feet. Statistical comparison of range of motion showed that the group with symptomatic plantar fasciitis was significantly restricted compared to both control and unaffected contralateral feet groups. Statistical comparison of peak torque showed that the symptomatic plantar fasciitis group was significantly lower than both other groups at both velocities. This study documents strength and flexibility deficits in the supporting musculature of the posterior calf and foot that are affected by plantar fasciitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Current treatment of plantar fasciitis.

Plantar fasciitis is one of the most common complaints of chronic rearfoot heel pain seen by primary care providers. The etiology and differential diagnosis are numerous, as are treatment options. This article includes a definition of plantar fasciitis, anatomy, predisposing factors, physical examination techniques, differential diagnosis, and conservative nonsurgical treatment options. Plantar fasciitis may be acute, but is more often a chronic condition that is directly related to physical activity. The most common complaint is intense heel pain with the first step from bed in the morning and initial step after resting. This pain subsides with time, but returns in the evening after prolonged standing.

A retrospective study of standing gastrocnemius-soleus stretching versus night splinting in the treatment of plantar fasciitis.

Plantar fasciitis is the most common cause of heel pain, yet the conservative treatment of plantar fasciitis is not standardized. This open retrospective study compared the effects of standing gastrocnemius-soleus stretching to a prefabricated night splint. One hundred and sixty patients with unilateral or bilateral plantar fasciitis were evaluated and treated according to the standard regimen in addition to either night splints or stretching. Seventy-one patients performed standing stretching of the gastrocnemius-soleus complex. Eighty-nine patients utilized the prefabricated night splint without standing stretching. The night splint treatment group had a significantly shorter recovery time (p < .001), fewer follow-up visits to recovery (p < .001), and fewer total additional interventions (p = .034) compared to the stretching group. Absolute body weight, body mass index, and age did not have a statistically significant effect on the time to recovery or additional interventions needed. The duration of pain prior to this treatment was a predictive factor and was associated with increased time to recovery and increased number of treatment interventions. Its was concluded that early treatment in a standardized four-tiered treatment approach, including the night splint without standing stretching of the gastrocnemius-soleus complex, speeds time to recovery.

Treatment of plantar fasciitis.

Plantar fasciitis is a common cause of heel pain in adults. The disorder classically presents with pain that is particularly severe with the first few steps taken in the morning. In general, plantar fasciitis is a self-limited condition. However, symptoms usually resolve more quickly when the interval between the onset of symptoms and the onset of treatment is shorter. Many treatment options exist, including rest, stretching, strengthening, change of shoes, arch supports, orthotics, night splints, anti-inflammatory agents and surgery. Usually, plantar fasciitis can be treated successfully by tailoring treatment to an individual's risk factors and preferences.

Scintigraphic localisation of steroid injection site in plantar fasciitis.

Plantar fasciitis is a common cause of heel pain. We evaluated scintigraphic localisation of the inflammatory focus in 15 patients with this condition. Technetium-labelled bone scans precisely localised abnormal discrete areas of tracer uptake in 12 (80%) of patients in the medial and posterior aspect below the inferior surface of the calcaneum. Steroid injection at the inflammatory site abolished local tenderness and reduced pain in all 12. Our findings support an injection approach through the medial heel border posterior to the point of heel tenderness. Technetium scintigraphy may be a useful investigation to localise the steroid injection site in resistant cases of plantar fasciitis.

The diagnosis and management of plantar fasciitis.

Plantar fasciitis is the most common diagnosis for pain in the inferior aspect of the heel and accounts for 10% of running injuries seen. It primarily afflicts the middle-aged and elderly populations and athletes. The diagnosis is relatively easy for the primary care provider to establish because of the typical presentation. Diagnostic studies usually are not warranted, but a careful history and physical examination are essential in identifying various predisposing anatomical, biomechanical, and environmental factors. This article addresses a wide array of conservative measures available in developing an individualized management approach based on the contributing factors identified. Because 90% or more respond to conservative measures, the primary care provider can manage the care of the majority of clients who present with plantar fasciitis. To avoid painful recurrence, measures effective in relieving symptoms need to be included in an ongoing plan of prevention.

Results of surgery in athletes with plantar fasciitis.

Plantar fasciitis is a common cause of pain, particularly in runners and certain other athletic groups. This syndrome must be distinguished from certain other conditions, such as the tarsal tunnel syndrome and achillodynia. Conservative therapy including rest, orthotics, heel cups, anti-inflammatory agents, and icing reduce symptoms in most patients. A few athletes may need surgery to continue running. The authors released the plantar fascia and excised areas of mucinoid degeneration in 15 athletes. Fourteen returned to full athletic activity.

Use of posterior night splints in the treatment of plantar fasciitis.

Plantar fasciitis is a frequent cause of heel pain in athletes, as well as in persons who are not involved in sports. Stretching, strengthening, correction of training errors and orthotics are essential components in any treatment program. For patients who do not respond to these interventions, posterior night splints can obviate the need for invasive therapies such as corticosteroid injections and surgery.

Impact of demographic and impairment-related variables on disability associated with plantar fasciitis.

BACKGROUND: Plantar fasciitis is a common foot disorder that impacts many functional activities. Research that quantifies the impact that plantar fasciitis has on function is lacking. In addition, little is known about which variables are associated with disability in patients with plantar fasciitis. The first purpose of this study was to determine if age, gender, body mass index, pain intensity, chronicity of symptoms, or ankle dorsiflexion range of motion was associated with disability in patients with plantar fasciitis. The second purpose was to describe the impact that plantar fasciitis has on functional status in the context of five functional domains: household activities of daily living, usual work and hobbies, nonweightbearing activities, walking-related activities, and running-related activities. METHODS: Fifty consecutive patients diagnosed with unilateral plantar fasciitis were recruited. Demographic and impairment data were collected and all patients completed the Lower Extremity Functional Scale (LEFS), a validated self-report measure of disability. Multiple regression analysis was used to describe the association between the variables and disability. Graphs depicting five domains of function derived from the LEFS were generated to describe the extent of disability. RESULTS: Body mass index (BMI) was the only variable that was significantly associated with disability (F = 9.87, p =.003). Measures of pain intensity, ankle dorsiflexion, age, gender, chronicity, and time spent weightbearing were not related to disability. Plantar fasciitis showed distinct patterns of disability depending on the functional domain that was assessed. CONCLUSIONS: With the exception of BMI, impairment and demographic variables do not predict the extent of functional loss in patients with plantar fasciitis. The most likely domains of function to be at least moderately affected in patients with plantar fasciitis are running-related activities and usual work or hobbies.

The role of hamstring tightness in plantar fasciitis.

BACKGROUND: Plantar fasciitis is a repetitive microtrauma overload injury of the attachment of the plantar fascia at the inferior aspect of the calcaneus. Several etiological factors have been implicated in the development of plantar fasciitis; however, the role of hamstring tightness has not been evaluated. METHODS: Fifteen volunteers (mean age 32.6 +/- 4.7 years) were prospectively analyzed for differences in forefoot loading using a Don-Joy brace (dj Orthopedics, Vista, CA) applied to each knee simultaneously. The brace was locked at varying degrees of knee flexion (0 degrees, 20 degrees, and 40 degrees). Their mean popliteal angle was 6.5 degrees. Fifteen patients (mean age 40 +/- 16.5 years) with a diagnosis of chronic plantar fasciitis were similarly analyzed on the pedobarograph. These patients also had their hamstring tightness evaluated by measuring the popliteal angle. The mean popliteal angle was 23 degrees. RESULTS: Increasing the angle of flexion from 0 to 20 degrees at the knee joint led to a statistically significant increase in pressure in the forefoot phase by an average of 0.08 K/cm(2)s (p < 0.05). An increase from 20 to 40 degrees led to increased forefoot phase pressure of 0.08 kg/cm(2)s (p < 0.05). The percentage of time spent in contact phase decreased from 35.37% to 30.87% to 26.37% with increasing flexion (p < 0.05). However there was an inverse increase in the time spent in the forefoot phase 46.6% to 55.6 to 61.25% with increasing degrees of flexion (p < 0.05). CONCLUSION: The results indicate that an increase in hamstring tightness may induce prolonged forefoot loading and through the windlass mechanism be a factor that increases repetitive injury to the plantar fascia.

The Effect of Pulsed Electromagnetic Field on Pain and Foot Function Index in Patients With Plantar Fasciitis.

The plantar fascia is a thick band of connective tissue that originates from the heel, and its inflammation is the most common cause of heel pain in adults. The Pulsed Electromagnetic Field (PEMF) is a non-invasive modality in the field of physiotherapy. This study aimed to determine the effects of PEMF on pain scores and the Foot Function Index (FFI) in patients with plantar fasciitis (PF). In this clinical trial study, 40 patients with PF, aged between 20 and 68 years, were randomly assigned in a block design into two groups: the Conventional Physiotherapy (CP) group and the CP plus PEMF (CPP) group. The Numerical Pain Rating Scale (NPRS) and the FFI questionnaire were used to assess the pain score (morning and evening pain) and foot function, respectively. Assessments were conducted before the study, at the tenth session of the CP and CPP groups, and 4 weeks later. The study variables in both the CP and CPP groups changed significantly (p < 0.05). In comparing the results between the two groups, the reduction in evening pain scores in the CPP group was significant compared to the CP group (p < 0.05). In comparison, there was no significant difference in morning pain scores between the two groups. The FFI score in the CPP group significantly decreased compared to the CP group. Both CP and CPP are effective in reducing pain and the FFI in patients with PF. The addition of PEMF to CP demonstrates a more significant effect on reducing evening pain and somewhat on reducing the FFI in patients compared to CP alone. However, it did not have an additional effect on reducing morning pain. Bioelectromagnetics. 00:00-00, 2026. © 2026 Bioelectromagnetics Society.

Electrohydraulic high-energy shock-wave treatment for chronic plantar fasciitis.

BACKGROUND: Plantar fasciitis is a common foot disorder that may be resistant to nonoperative treatment. This study evaluated the use of electrohydraulic high-energy shock waves in patients who failed to respond to a minimum of six months of antecedent nonoperative treatment. METHODS: A randomized, placebo-controlled, multiply blinded, crossover study was conducted. Phase 1 consisted of twenty patients who were nonrandomized to treatment with extracorporeal shock waves to assess the phase-2 study protocol. In phase 2, 293 patients were randomized and an additional seventy-one patients were nonrandomized. Following ankle-block anesthesia, each patient received 100 graded shocks starting at 0.12 to 0.22 mJ/mm(2), followed by 1400 shocks at 0.22 mJ/mm(2) with use of a high-energy electrohydraulic shock-wave device. Patients in the placebo group received minimal subcutaneous anesthetic injections and nontransmitted shock waves by the same protocol. Three months later, patients were given the opportunity to continue without further treatment or have an additional treatment. This allowed a patient in the active treatment arm to receive a second treatment and a patient who received the placebo to cross over to the active treatment arm. Patients were followed at least one year after the final treatment. RESULTS: Treatment was successful in seventeen of the twenty phase-1 patients at three months. This improved to nineteen (95%) of twenty patients at one year and was maintained at five years. In phase 2, three months after treatment, sixty-seven (47%) of the 144 actively treated patients had a completely successful result compared with forty-two (30%) of the 141 placebo-treated patients (p = 0.008). At one year, sixty-five of the sixty-seven actively treated, randomized patients maintained a successful result. Thirty-six (71%) of the remaining fifty-one nonrandomized patients had a successful result at three months. For all 289 patients who had one or more actual treatments, 222 (76.8%) had a good or excellent result. No patient was made worse by the procedure. CONCLUSIONS: The application of electrohydraulic high-energy shock waves to the heel is a safe and effective noninvasive method to treat chronic plantar fasciitis, lasting up to and beyond one year.

Bone scintigraphy predicts outcome of steroid injection for plantar fasciitis.

UNLABELLED: Plantar fasciitis is a common cause of foot pain and may be disabling. Although localized injection is painful, anesthetics or corticosteroids can relieve symptoms well. Bone scintigraphy can confirm the diagnosis. We hypothesized that blood-pool abnormalities could provide prognostic information on the response to such injections. METHODS: We devised scintigraphic criteria that graded the blood-pool abnormalities as being localized to the plantar enthesis, being localized to half the length of the aponeurosis, or involving the whole aponeurosis. We evaluated 24 patients with an established diagnosis of plantar fasciitis, 8 of whom had bilateral disease, leading to a total of 32 feet injected. RESULTS: After injection, pain was relieved either completely or nearly completely in 20 feet. The other 12 feet had short-term or no improvement, with persistent pain and loss of function at 4-5 wk after injection. Of the 20 feet responding to injection, 14 had focal hyperemia on blood-pool images and 6 had minimal extension into the proximal third of the plantar soft tissues. No patient with diffuse hyperemia in the plantar fascia had a response (5/12 feet). On the delayed images of the 20 responders, mild inferior calcaneal uptake was seen in 8 feet, moderate uptake in 6, and severe uptake in 6. These groups did not significantly differ (P > 0.05). The blood-pool studies had good reproducibility, with a kappa-value of 0.64. CONCLUSION: Critical evaluation of plantar blood-pool images provides prognostic information on the response to localized injection into the enthesis. Reporting such studies is simple and reproducible.
