Physical Therapy Diagnosis and Management of a Patient with Chronic Daily Headache: A Case Report

Abstract

Chronic headaches are a significant health problem for patients and often a clinical enigma for the medical professionals who treat such patients. The purpose of this case report is to describe the physical therapy diagnosis and management of a patient with chronic daily headache. The patient was a 48-year-old woman with a medical diagnosis of combined common migraine headache and chronic tension-type headache. An exacerbation of these long-standing headache complaints had resulted in a chronic daily headache for the preceding eight months. Symptoms included bilateral headache, neck pain, left facial pain, and tinnitus. Outcome measures used included the Henry Ford Hospital Headache Disability Inventory (HDI) and the Neck Disability Index (NDI). Examination revealed myofascial, articular, postural, and neuromuscular impairments of the head and neck region. Treatment incorporated myofascial trigger point dry needling, orthopaedic manual physical therapy, exercise therapy, and patient education. On the final visit, the patient reported no headaches during the preceding month. There was a 31% improvement in the HDI emotional score, a 42% improvement in the functional score, and a 36% improvement in the total score for the HDI, the latter exceeding the minimal detectable change for the total score on this measure. The NDI at discharge showed an 18% improvement with a maximal improvement during the course of treatment of 26%. Both improvements exceeded the minimal clinically important difference for the NDI. This case report indicates that physical therapy diagnosis and management as described may be indicated for the conservative care of patients with chronic headaches.     

Ultrasound Imaging of Embedded Shrapnel Facilitates Diagnosis and Management of Myofascial Pain Syndrome

Trigger points can result from a variety of inciting events including muscle overuse, trauma, mechanical overload, and psychological stress. When the myofascial trigger points occur in cervical musculature, they have been known to cause headaches. Ultrasound imaging is being increasingly used for the diagnosis and interventional management of various painful conditions. A veteran was referred to the pain clinic for management of his severe headache following a gunshot wound to the neck with shrapnel embedded in the neck muscles a few years prior to presentation. He had no other comorbid conditions. Physical examination revealed a taut band in the neck. An ultrasound imaging of the neck over the taut band revealed the deformed shrapnel located within the levator scapulae muscle along with an associated trigger point in the same muscle. Ultrasound guided trigger point injection, followed by physical therapy resolved his symptoms. This is a unique report of embedded shrapnel and coexisting myofascial pain syndrome revealed by ultrasound imaging. The association between shrapnel and myofascial pain syndrome requires further investigation.     

Quantification of changes in myofascial trigger point sensitivity with the pressure algometer following passive stretch

In order to determine the relationship between trigger point sensitivity and the referred symptoms of myofascial pain, VAS ratings of referred pain intensity and pressure algometer measures of myofascial trigger point sensitivity were taken pre and post treatment of the muscle containing the trigger point with passive stretch. The results in 20 subjects, experiencing unilateral or bilateral myofascial head and neck pain, showed that myofascial trigger point sensitivity decreases in response to passive stretch as assessed by the pressure algometer, and that trigger point sensitivity and intensity of referred pain are related.     

Pure Tension-type Headache Versus Tension-type Headache in the Migraineur

Primary headache disorders include tension-type headache and migraine. These headache types can be differentiated based on strict clinical definitions that depend on the patient’s signs and symptoms. However, some of the clinical features can overlap, and in addition, the same comorbid conditions can occur in both headache types. Distinction between these headache types on occasion can be difficult due to comorbid conditions such as temporomandibular joint disorders and myofascial pain with forward head posturing, which may be present in both headache disorders, and thus result in similar features in both conditions. Furthermore, chronification, particularly of migraine, leads to a decrease in the associated symptoms of migraine, such as nausea, photophobia, and phonophobia, so that these headaches more closely resemble tension-type headache. Finally, in some patients, both tension-type headache and migraine may occur at different times.     

Otolaryngic myofascial pain syndromes

It has been long recognized in the otolaryngic community that despite great effort dedicated to the physiology and pathology of the ear, nose, throat/head and neck, there are a number of symptoms, including pain in various locations about the head and neck, which cannot be explained by traditional otolaryngic principles. The tenets of myofascial dysfunction, however, as elucidated by Dr. Janet Travell, explain most of these previously unexplained symptoms; furthermore, treatment based on Dr. Travell’s teachings is effective in relieving these symptoms.     

The effectiveness of acupuncture in the management of persistent regional myofascial head and neck pain: A systematic review and meta-analysis

Persistent head and neck myofascial pain is among the most frequently reported pain complaints featuring major variability in treatment approaches and perception of improvement. Acupuncture is one of the least invasive complimentary modalities that can optimize conventional treatment. The aim of this review was to determine the evidence for the effectiveness of acupuncture in the management of localized persistent myofascial head and neck pain. Only randomized controlled clinical trials (RCTs) were included. The search was conducted in PubMed, Ovid Medline, Embase, Google Scholar, and Cochrane Library in addition to manual search. The main outcome measure was the comparison of the mean pain intensity score on VAS between acupuncture and sham-needling/no intervention groups. Safety data and adherence rate were also investigated. Six RCTs were identified with variable risk of bias. All included studies reported reduction in VAS pain intensity scores in the groups receiving acupuncture when compared to sham needling/no intervention. Meta-analysis, using a weighted mean difference as the effect estimate, included only 4 RCTs, revealed a 19.04 point difference in pain intensity between acupuncture and sham-needling/no intervention (95 %CI: -29.13 to -8.95). High levels of safety were demonstrated by the low rates of side effects/withdrawal. Inconsistency in reporting of outcomes was a major limitation. In conclusion, moderate-quality evidence suggests that acupuncture may be an effective and safe method in relieving persistent head and neck myofascial pain. Optimizing study designs and standardizing outcome measures are needed for future RCTs.     

Possible Identification of Cervicogenic Headache Among Patients With Migraine: An Analysis of 374 Headaches

According to Sjaastad, the pain in cervicogenic headache, a form not recognized by the IHS, is long lasting and always side-locked unilateral. The frequency of side-locked unilateral pain (defined here as no change in side from onset) and other characteristics of cervicogenic headache were investigated in 300 outpatients using information collected on standard forms in structured interviews. Three hundred seventy-four headaches diagnosed according to IHS criteria were identified. Three hundred forty-eight of these headaches were long-lasting (duration of more than 4 hours); migraine (65%) followed by tension-type headache (25%) were the commonest forms. Side-locked unilaterality was present in 29% (101 of 348), and occurred most frequently in migrainous disorders not fulfilling the criteria (25 of 56, 44.6%). This group differed significantly from the other migraine conditions for longer pain duration ( P <0.02) and less frequent nausea, vomiting, photophobia, phonophobia ( P <0.0001), and aggravation by physical activity ( P <0.02). With these characteristics, this group resembled cervicogenic headache. However, in none of these patients was pain triggered by head or neck movements, and the frequency of head or neck trauma did not differ from other headaches. A more precise definition of clinical criteria for cervicogenic headache vs migraine is, therefore, required.     

Difficult problems and their solutions in patients with cancer pain of the head and neck areas

Pain management can be especially difficult in patients with head and neck cancer due to the erosive nature of the neoplasms that invade the region, the rich innervation of the head and neck, and other factors. Consequently, diagnosis is a complex process that cannot be dealt with in a cursory fashion. Furthermore, tumor pain can mimic noncancer conditions, nonmalignant orofacial disorders can be suggestive of tumor growth, and antineoplastic treatment-related conditions can be difficult to distinguish from tumor recurrence. A series of case reports illustrates key elements of diagnosis and pain management in patients with head and neck cancer. These elements include 1) detailed assessment of pain intensity and characteristics; 2) appropriate use of analgesic adjuvant medications; 3) use of diagnostic and therapeutic nerve blocks and myofascial trigger point injections; and 4) a high index of suspicion regarding tumor recurrence pain.     

Management of Chronic Head and Neck Pain: Effectiveness of Altering Factors Perpetuating Myofascial Pain

SYNOPSIS
The response of 25 chronic myofascial head and neck pain patients to a systematic musculoskeletal rehabilitation program was examined. The program emphasized the acquisition of self-management skills through a highly structured interdisciplinary format. Physical and cognitive behavioral therapies were aimed at reducing factors which perpetuate myofascial pain. Results immediately following treatment, and at three, six and twelvemonths post-treatment when compared to pretreatment scores, showed highly reliable reductions in self-reports of pain and medication intake.     

Are "cervicogenic" headaches due to myofascial pain and cervical spine dysfunction?

The purpose of this investigation was to evaluate whether the pain of cervicogenic headache could be due to referred symptoms from myofascial trigger points. The presence or absence of cervical spine dysfunction was also of interest. Eleven patients with cervicogenic headaches were systematically examined for myofascial trigger points and cervical spine dysfunction. All patients had at least three myofascial trigger points on the symptomatic side. In eight of these patients, trigger point palpation clearly reproduced their headache. There were 70 myofascial trigger points (35 "very tender", 35 "tender") and 17 non-myofascial tender points on the symptomatic side, compared to 22 myofascial trigger points (one "very tender", 21 "tender") and 19 non-myofascial tender points on the asymptomatic side. These differences were statistically significant [chi-square (2df) = 22.04, p less than 0.0001]. All patients had some evidence of cervical dysfunction. Ten patients (91%) had specific segmental dysfunction of occiput on atlas and/or atlas on axis. Five patients were entered into a non-invasive, interdisciplinary pain management program designed to treat cervical spine dysfunction and myofascial pain. Treated patients reported a significant decrease in the frequency and intensity of their headaches during a median two-year follow-up. It is concluded that myofascial trigger points may be an important pain producing mechanism in cervicogenic headache and that segmental cervical dysfunction is a common feature in such patients. Conservative, non-surgical treatment appears to be effective in reducing the frequency and intensity of cervicogenic headache. These data suggest that surgical approaches should be reserved only for those patients who fail conservative therapy.     

Musculoskeletal head and neck pain

Musculoskeletal head and neck pain is an extremely common clinical syndrome in outpatient pain practice. Cervical structures are a frequent cause of headache and must be differentiated from primary headache disorders. Convergence of cervical and trigeminal nociceptive pathways in the upper part of the cervical spinal cord is the neurophysiologic basis of this connection. An interdisciplinary pain management approach that addresses psychosocial factors, pharmacologic and interventional pain management and incorporates progressive exercise training is most likely to be effective. This review discusses the comprehensive evaluation and management of musculoskeletal head and neck pain with a focus on cervicogenic headache, cervical myofascial pain, and temperomandibular dysfunction.     

Vacuum myofascial therapy device for non-specific neck pain. A single blind randomized clinical trial

ObjectivesThis study aimed to investigate the efficacy of a vacuum myofascial therapy device (VT) for improving pressure pain thresholds (PPTs), range of motion (ROM), neck pain-related disability, pain, and quality of life in patients with non-specific neck pain.MethodsA randomized controlled trial in which thirty-eight participants with non-specific neck pain (NP) were randomly assigned to either an experimental (VT) or a comparison physical therapy program (PTP) group. The VT group (n = 19) received five sessions of treatment with a vacuum myofascial therapy device while the PTP group (n = 19) received five sessions of massage, ultrasound therapy (US), and transcutaneous electric nerve stimulation (TENS) over two weeks. The outcome measures were the numerical pain rating scale (NPRS), range of motion, quality of life (SF-12), neck disability Index (NDI), and PPTs at the end of treatment and at one-month follow-up.ResultsAlthough both groups experienced improvements in pain, neck disability, range of motion, and pressure pain, these only were statistically significant in the VT group. At one-month follow-up, the VT group still showed improvements in pain, neck disability, and range of motion.DiscussionVacuum myofascial therapy applied with a device offers similar results to other vacuum-based techniques such as cupping therapy. Moreover, in this device the parameters are digitally controlled, which allows for the precise reproduction of treatment.     

Dry needling for the management of thoracic spine pain

Abstract

Thoracic spine pain is as disabling as neck and low back pain; however, it has not received as much attention as the cervical and lumbar spine in the scientific literature. Among the different structures that can refer pain to the thoracic spine, muscles often play a relevant role. In fact, myofascial trigger points (TrPs) from several neck, shoulder and spinal muscles can induce pain in the region of the thoracic spine. There is a lack of evidence reporting the presence of myofascial TrPs in the thoracic spine, but clinical evidence suggests that TrPs can be a potential source of thoracic spine pain. The current paper discusses the role of myofascial TrPs in the thoracic spine and summarises the proper and safe application of dry needling (DN) for the management of myofascial TrPs in two main spinal muscles involved in thoracic spine pain: the thoracic multifidi and longissimus thoracis. In addition, this paper discusses the application of DN in other tissues such as tendons, ligaments and scars.     

Analysis of chronic myofascial pain in the upper trapezius muscle of breast cancer survivors and women with neck pain

Myofascial trigger points are present in dysfunctioning muscles and are associated with several diseases. However, the scientific literature has not established whether myofascial trigger points of differing etiologies have the same clinical characteristics. Thus, the objective of the present study was to compare the intensity of myofascial pain, catastrophizing, and the pressure pain threshold at myofascial trigger points among breast cancer survivors and women with neck pain. This was a cross-sectional study that included women over 18 years old complaining of myofascial pain in the upper trapezius muscle region for more than 90 days, equally divided into breast cancer survivors (n = 30) and those with neck pain (n = 30). For inclusion, the presence of a bilateral, active, and centrally located trigger point with mean distance from C7 to acromion in the upper trapezius was mandatory. The measures of assessment were: pain intensity, catastrophizing, and the pressure pain threshold at the myofascial trigger points. A significant difference was observed only when comparing pain intensity (p < 0.001) between the breast cancer survivors (median score: 8.00 points, first quartile: 7.00 points, third quartile: 8.75 points) and women with neck pain (median score: 2.50 points, first quartile: 2.00 points, third quartile: 4.00 points). No significant difference was found between groups in catastrophizing and pressure pain threshold. The conclusion of this study was that breast cancer survivors have a higher intensity of myofascial pain in the upper trapezius muscle when compared to patients with neck pain, which indicates the need for evaluation and a specific intervention for the myofascial dysfunction of these women.     

On the problem of post-traumatic headache

Posttraumatic headache is a general term for pain localized in the head or neck, occurring after head trauma and of varied aetiology and pathogenesis. In many cases one only finds a time-dependent relation to trauma, but no causal one. There is no uniform, typical "posttraumatic headache". The headaches are commonly caused by injury to scalp, cervical spine and intracranial structures. A reciprocal influence exists between these functionally disturbed structures and a relation to psychogenic factors, which are essential co-factors. Usually it is difficult to decide whether posttraumatic headaches are exclusively caused by organic or psychogenic factors. Probably both factors are involved to an individually different degree.     

Whiplash headache is transitory worsening of a pre-existing primary headache

Acute and chronic whiplash headache are new diagnostic entities in the ICHD-2 (5.3, 5.4). In a prospective cohort study, 210 rear-end collision victims were identified consecutively from police records and asked about head and neck pain in questionnaires after 2 weeks, 3 months and 1 year. The results were compared with those of matched controls who were also followed for 1 year. Of 210 accident victims, 75 developed headache within 7 days. Of these, 37 had also neck pain and complied with the criteria for acute whiplash headache. These 37 had the same headache diagnoses, headache features, accompanying symptoms and long-term prognosis as the 38 without initial neck pain who therefore did not comply with the acute whiplash headache diagnosis. Previous headache was a major risk factor for headache both in the acute and chronic stage. Compared with the non-traumatized controls, headache in the whiplash group had the same prevalence, the same diagnoses and characteristic features, and the same prognosis. Both acute and chronic whiplash headache lack specificity compared with the headache in a control group, and have the same long-term prognosis, indicating that such headaches are primary headaches, probably elicited by the stress of the situation.     

Trigger points and myofascial pain: toward understanding how they affect headaches

Myofascial pain, referred from hyperalgesic trigger points located in skeletal muscle and its associated fascia, is a common cause of persistent regional pain. Clinical and experimental literature on manifestations, pathophysiology, and management of pain from myofascial trigger points is reviewed with priority given to how pain referred from trigger points generates, triggers, and maintains headaches—especially chronic and recurrent ones. Because treating myofascial problems may be the only way to offer complete relief from certain types of headache, clinicians must learn to diagnose and manage trigger points in neck, shoulder, and head muscles.     

Mild Head Trauma and Chronic Headaches in Returning US Soldiers

Objective.— To determine the incidence and types of head or neck trauma and headache characteristics among US Army soldiers evaluated for chronic headaches at a military neurology clinic following a combat tour in Iraq. Background.— Head or neck trauma and headaches are common in US soldiers deployed to Iraq. The temporal association between mild head trauma and headaches, as well as the clinical characteristics of headaches associated with mild head trauma, has not been systematically studied in US soldiers returning from Iraq. Methods.— A retrospective cohort study was conducted with 81 US Army soldiers from the same brigade who were evaluated at a single military neurology clinic for recurrent headaches after a 1‐year combat tour in Iraq. All subjects underwent a standardized interview and evaluation to determine the occurrence of head or neck trauma during deployment, mechanism and type of trauma, headache type, and headache characteristics. Results.— In total, 33 of 81 (41%) soldiers evaluated for headaches reported a history of head or neck trauma while deployed to Iraq. A total of 18 (22%) subjects had concussion without loss of consciousness and 15 (19%) had concussion with loss of consciousness. Ten subjects also had an accompanying traumatic neck injury. No subjects had moderate or severe traumatic brain injury. Exposure to blasts was the most common cause of trauma, accounting for 67% of head and neck injuries. Headaches began within one week after trauma in 12 of 33 (36%) soldiers with head or neck injury. Another 12 (36%) reported worsening of pre‐existing headaches after trauma. Headaches were classified as migraine type in 78% of soldiers with head or neck trauma. Headache types, frequency, severity, duration, and disability were similar for soldiers with and without a history of head or neck trauma. Conclusion.— A history of mild head trauma, usually caused by exposure to blasts, is found in almost half of returning US combat troops who receive specialized care for headaches. In many cases, head trauma was temporally associated with either the onset of headaches or the worsening of pre‐existing headaches, implicating trauma as a precipitating or exacerbating factor, respectively. Headaches in head trauma‐exposed soldiers are usually migraine type and are similar to nontraumatic headaches encountered at a military specialty clinic.
