Chiropractic rehabilitation of a patient with S1 radiculopathy associated with a large lumbar disk herniation

OBJECTIVE: To describe the nonsurgical treatment of acute S1 radiculopathy from a large (12 x 12 x 13 mm) L5-S1 disk herniation. CLINICAL FEATURES: A 31-year-old man presented with severe lower back pain and pain, paresthesia, and plantar flexion weakness of the left leg. His symptoms began 5 days before the initial visit and progressed despite nonsteroidal anti-inflammatory drugs and analgesic medication. An absent left Achilles reflex, left S1 dermatome hypesthesia, and left gastrocnemius/soleus weakness was noted. Magnetic resonance imaging demonstrated a large L5-S1 disk herniation. INTERVENTION AND OUTCOME: Initial treatment of this patient included McKenzie protocol press-ups to reduce and centralize symptoms, nonloading exercise for cardiovascular fitness, and lower leg isotonic exercises to prevent atrophy. Counseling was provided to reduce abnormal illness behavior risk. Later, flexion distraction and side-posture manipulation were provided to improve joint function. Sensory motor training, trunk stabilization exercises, and trigger point therapy were also used. He returned to modified work 27 days after symptom onset. A follow-up, comparative magnetic resonance imaging (MRI) study was unchanged. He was discharged as symptomatic (zero rating on both the Oswestry and numerical pain scales) after 50 days and 20 visits, although the left S1 reflex remained absent. Reassessment 169 days later revealed neither significant symptoms nor lifestyle restrictions. CONCLUSION: This case demonstrates the potential benefit of a chiropractic rehabilitation strategy by use of multimodal therapy for lumbar radiculopathy associated with disk herniation.     

Management of acute lumbar disk herniation initially presenting as mechanical low back pain.

OBJECTIVE: To describe the clinical management with spinal manipulation of a male patient with risk factors for lumbar disk herniation initially suffering from what appeared to be mechanical low back pain that evolved into radiculopathy; also to review issues pertinent to chiropractic/manipulative management of disk herniation. CLINICAL FEATURES: The patient initially suffered from unilateral low back pain and nonradicular/nonlancinating referral to the ipsilateral lower extremity. INTERVENTION AND OUTCOME: Disk herniation-in-evolution was included in the differential diagnosis, which was discussed with the patient, who then gave verbal informed consent for manipulative management. A day or so after the initial manipulation the presentation evolved to include S1 radiculopathy. Computed tomography, just after onset of radiculopathy, confirmed the clinical diagnosis of lumbosacral disk herniation. The patient continued with manipulative management and repeat computed tomography examination after clinical resolution about 2 months later revealed reduction in size of the apparently clinically significant herniation. CONCLUSION: Risk factors for the development of disk herniation should be considered when assessing patients suffering from what appears to be mechanical low back pain. The role played by manipulation in the development of disk herniation in this case was believed to be circumstantial rather than causal. Manipulation was used in the treatment of this patient over a period of approximately 2 months; after this time, clinical and partial computed tomography imaging resolution was evident. Ongoing clinical (neurologic) evaluation of patients with manifest or suspected disk herniation is an important aspect of management. Good-quality trials of manipulation for patients with disk herniation are imperative for the chiropractic profession.     

Chiropractic care of a patient with vertebral subluxations and unsuccessful surgery of the cervical spine

OBJECTIVE: The chiropractic care of a patient with vertebral subluxations, neck pain, and cervical radiculopathy after a cervical diskectomy is described. CLINICAL FEATURES: A 55-year-old man had neck pain and left upper extremity radiculopathy after unsuccessful cervical spine surgery. INTERVENTION AND OUTCOME: Contact-specific, high-velocity, low-amplitude adjustments (i.e., Gonstead technique) were applied to sites of vertebral subluxations. Rehabilitation exercises were also used as adjunct to care. The patient reported a decrease in neck pain and left arm pain after chiropractic intervention. The patient also demonstrated a marked increase in range of motion (ROM) of the left glenohumeral articulation. CONCLUSION: The chiropractic care of a patient with neck pain and left upper extremity radiculopathy after cervical diskectomy is presented. Marked resolution of the patient's symptoms was obtained concomitant with a reduction in subluxation findings at multiple levels despite the complicating history of an unsuccessful cervical spine surgery. This is the first report in the indexed literature of chiropractic care after an unsuccessful cervical spine surgery.     

Resolution of pronounced painless weakness arising from radiculopathy and disk extrusion

In this retrospective, consecutive case series, we report the nonsurgical and rehabilitation outcomes of consecutive patients who presented with pronounced painless weakness arising from disk extrusion. Seven consecutive patients who chose physiatric care were followed clinically, and strength return was monitored. Each presented with predominantly painless radiculopathy, functionally significant strength loss, and radiographic evidence of disk extrusion or sequestration. Each patient participated in a targeted strengthening program, and in some cases, transforaminal injection therapy was employed. Each patient demonstrated an eventual full functional recovery. In most cases, electrodiagnostic studies were performed and included a needle examination of the affected limb and compound muscle action potentials from the most clinically relevant and weakened limb muscle. The electrodiagnostic findings and, in particular, the quantitative compound muscle action potential data seemed to correlate with the timing of motor recovery. Patients with predominantly painless and significant weakness arising from disk extrusion can demonstrate successful rehabilitation outcomes. Despite a relative absence of pain, such patients can present with a more rapidly reversible neurapraxic type of weakness. The more quantitative compound muscle action potential data obtained through electrodiagnostic studies may offer the treating physician an additional means of characterizing the type of neuronal injury at play and the likelihood and timing of strength return.     

Outcomes and adverse events from physiotherapy functional restoration for lumbar disc herniation with associated radiculopathy

Purpose.?To report the outcomes and adverse events of people diagnosed with lumbar disc herniation with associated radiculopathy (LDHR) who were treated with a physiotherapy functional restoration programme.

Method.?Data on functional outcome (Oswestry score), work status, global rating of change, and adverse events were extracted from the files of all people with LDHR treated by three physiotherapists using functional restoration principles from 2001 to 2009.

Results.?Ninety-five participants were included. The Oswestry score reduced by a mean of 15.9 (95%% CI, 11.8–20.1) points between baseline and discharge following a mean (SD) of 8.7 (9.4) months of treatment. The proportion of participants working full-time increased from 37%% to 67%% between baseline and discharge (p < 0.001). Eighty per cent of participants reported overall improvement between baseline and discharge on the global rating of change scale (p < 0.001). Minor adverse events were reported by eight (8%%) participants, while one (1%%) participant developed adhesive capsulitis.

Conclusion.?People with LDHR who undertook a physiotherapy functional restoration programme achieved significant improvements in Oswestry disability scores, work status, and global rating of change, with few adverse events reported. A randomised controlled trial is warranted to determine the efficacy of functional restoration for people with this condition.     

Lumbar intraspinal synovial cyst containing gas as a cause for low-back pain

OBJECTIVE: To discuss intraspinal synovial cysts caused by degenerative changes involving the posterior articular facets in the lumbar spine and to provide differential considerations for patients with low-back pain. Clinical Features: A 70-year-old man with low-back and gluteal pain demonstrating eventual progression of radiating pain into the left thigh, calf, ankle, and foot over a 5-month period. Radiographs of the lumbar spine revealed mild degenerative disk disease at L5-S1 with associated vacuum phenomena of the L5 disk. Degenerative osteophytes were present at L3, L4, and L5. Moderate posterior joint arthrosis was evident at L4-L5 and L5-S1. Computed tomography and magnetic resonance imaging studies revealed an intraspinal gas-containing synovial cyst at the left lateral aspect of the central canal at the level of the left L4-L5 facet articulation. Intervention and Outcome: The patient underwent surgical excision of the synovial cyst with remission of symptoms. CONCLUSION: Gas-containing intraspinal synovial cysts can be a significant finding and a causative factor in patients with low-back pain and pain radiating into the lower extremities. Both computed tomography and magnetic resonance imaging are important in defining intraspinal synovial cysts as a cause of back pain in patients whose low-back pain does not respond to chiropractic care.     

Acute flaccid paralysis associated with West Nile virus: motor and functional improvement in 4 patients

OBJECTIVE: To describe motor and functional recovery in 4 patients with acute flaccid paralysis associated with West Nile virus (WNV) infection. DESIGN: A case series describing patient clinical features at admission to rehabilitation through 6-month follow-up. SETTING: Academic acute free-standing inpatient rehabilitation hospital. PARTICIPANTS: The patients (3 men, 1 woman; age range, 29-72 y) with central nervous system WNV infection presented on rehabilitation admission, 18 to 112 days after onset of symptoms, with severe flaccid asymmetric weakness without sensory loss, and decreased functional independence. Electrodiagnostic studies demonstrated a severe diffuse motor axonopathy consistent with an anterior myelitis. INTERVENTION: Acute inpatient rehabilitation program over a period of 35 to 106 days. MAIN OUTCOME MEASURES: Motor and FIM instrument scores at admission to rehabilitation, discharge, and 6-month follow-up. RESULTS: All patients showed modest improvements in strength and function; no patient made full recovery of strength or became ambulatory by 6-month follow-up. CONCLUSIONS: Little is known about recovery in patients with WNV-associated anterior myelitis. It will be important to document any further improvements in strength and function in such patients over a longer follow-up period.     

Functional benefits are sustained after a program of supervised resistance exercise in cancer patients with bone metastases: longitudinal results of a pilot study

Introduction

Exercise may represent an effective adjunct therapy to current medical management strategies for maintaining functional independence and improving quality of life in cancer patients with bone metastatic disease. However, it has yet to be determined if there are any sustained effects following the completion of an exercise program by patients with bone metastases.

Purpose

The aim of this study is to determine whether a 3-month supervised resistance exercise program results in any sustained functional benefits in prostate and breast cancer patients with bone metastatic disease.

Methods

Twenty men and women with bone metastatic disease secondary to prostate or breast cancer completed a 3-month supervised resistance exercise program followed by a 6-month observation period. Outcomes were assessed at baseline, post-exercise, and 6-month follow-up.

Results

Fourteen participants completed the follow-up observation period. Significant improvements in physical function (4–6 %), physical activity levels (~160 min/week), lean mass (3–4 %), and quality of life (5–7 %) were observed at the completion of the exercise program. At the 6-month follow-up, significant improvements in ambulation (4 %), physical activity level (~105 min/week), whole body lean mass (2 %), and quality of life (13 %) remained.

Conclusions

An appropriately designed and supervised 3-month resistance exercise program may lead to significant improvements in functional ability, physical activity level, lean mass, and quality of life that remain 6 months after completion of the program in cancer patients with bone metastases. Future trials involving larger sample sizes are required to expand these preliminary findings.     

Chiropractic management using Cox cervical flexion-distraction technique for a disk herniation with left foraminal narrowing in a 64-year-old man

OBJECTIVE: The purpose of this case report is to describe chiropractic management of a patient with a C6/C7 left posteromedial disk herniation with foraminal narrowing and concomitant neurological compromise in the form of left upper extremity radiating pain and hypoesthesia/anesthesia using Cox flexion-distraction technique. CLINICAL FEATURES: A 64-year-old man presented to a chiropractic clinic with complaints of neck/left shoulder pain and hypoesthesia/anesthesia into the palmar side of his left hand. Magnetic resonance images of the cervical spine revealed a left posteromedial C6/C7 disk herniation along with foraminal narrowing. In addition, there were other levels of degeneration, most noted at the C3/C4 spinal level, which also had significant left-sided foraminal narrowing. INTERVENTION AND OUTCOME: Treatment included Cox flexion-distraction protocols aimed to reduce nerve root compression along with supportive physiological therapeutic interventions to aid with pain reduction and functional improvement. The patient was treated a total of 10 times over a course of 4 weeks. The patient reported being pain-free and fully functional 8 months following the conclusion of care. CONCLUSION: This case study demonstrated the use of Cox flexion-distraction for treatment of a patient with a cervical disk herniation, foraminal narrowing, and associated radiating pain and radiculopathy in the left upper extremity.     

A ganglion cyst causing lumbar radiculopathy in a baseball pitcher: a case report

This report describes a case of a professional baseball pitcher who developed acute left lumbar radicular symptoms after a baseball game and was subsequently sidelined for the rest of the season. Physical examination revealed depressed reflexes in the left posterior tibialis and left medial hamstring muscles, mild weakness in the left extensor hallucis longus, and positive dural tension signs. Magnetic resonance imaging demonstrated an ovoid mass at the L4-L5 level, causing compression of the dura. Surgical resection of the mass resulted in resolution of his symptoms. Pathology revealed that the mass was a ganglion cyst. A ganglion cyst is a rare cause of lumbar radiculopathy and should be considered in the differential diagnosis if a patient with lumbar radiculopathy fails to respond to conservative treatment.     

Thoracic disk herniation presenting as abdominal and pelvic pain: a case report

We report the case of a young woman who presented with a 2-month history of severe abdominal and pelvic pain. The past history was significant for a fall from a bicycle 1 week before the onset of her pain. Physical examination was remarkable for periumbilical tenderness. Work-up including pelvic sonogram and diagnostic laparoscopy suggested endomyometritis. The pain was minimally relieved by nonsteroidal anti-inflammatory drugs and narcotic analgesics. Thoracic spine magnetic resonance imaging (MRI) revealed a large disk herniation at the T9-10 level compressing the spinal cord. The patient subsequently underwent T9-10 diskectomy and laminectomy with dramatic relief of her symptoms. Postoperative rehabilitation hastened her functional improvement. This is a rare case of symptomatic thoracic disk herniation after trauma presenting as abdominal and pelvic pain. Physicians should be aware of this unusual presentation of thoracic disk herniation to avoid invasive diagnostic procedures.     

Use of a classification system to guide nonsurgical management of a patient with chronic low back pain

BACKGROUND AND PURPOSE: This case report describes the use of a classification system in the evaluation of a patient with chronic low back pain (LBP) and illustrates how this system was used to develop a management program in which the patient was instructed in symptom-reducing strategies for positioning and functional movement. CASE DESCRIPTION: The patient was a 55-year-old woman with a medical diagnosis of lumbar degenerative disk and degenerative joint disease from L2 to S1. Rotation with extension of the lumbar spine was found to be consistently associated with an increase in symptoms during the examination. Instruction was provided to restrict lumbar rotation and extension during performance of daily activities. OUTCOMES: The patient completed 8 physical therapy sessions over a 3-month period. Pretreatment, posttreatment, and 3-month follow-up modified Oswestry Disability Questionnaire scores were 43%, 16%, and 12%, respectively. DISCUSSION: Daily repetition of similar movements and postures may result in preferential movement of the lumbar spine in a specific direction, which then may contribute to the development, persistence, or recurrence of LBP. Research is needed to determine whether patients with LBP would benefit from training in activity modifications that are specific to the symptom-provoking movements and postures of each individual as identified through examination.     

Sciatic neuropathy secondary to a uterine fibroid: a case report

Lesions of the sciatic nerve outside the pelvis have been well described. Lesions within the pelvis, however, are far less common. We report the case of a 55-yr-old woman with a history of chronic low back pain who presented with progressive right buttock and posterolateral right lower limb pain associated with right foot numbness and tingling. She denied any associated low back or left lower limb pain. The patient was initially treated for a probable right lumbosacral radiculopathy, without improvement. A subsequent magnetic resonance image of the lumbosacral spine revealed multilevel disc degeneration at L3-4 through L5-S1, without disc herniation or canal stenosis. A magnetic resonance image of the pelvis revealed a markedly enlarged uterus, with a large pedunculated myoma impinging on the right sciatic foramen. The patient underwent a subtotal abdominal hysterectomy, with resolution of her right lower limb pain. This case illustrates the importance of considering intrapelvic causes of sciatic neuropathy. To our knowledge, this is the first reported case of sciatic neuropathy secondary to a uterine fibroid.     

Cardiac rehabilitation in patients with severe ischemic left ventricular dysfunction

Twenty patients who had had a myocardial infarction and who had a resting left ventricular ejection fraction of 25% or less participated in an 8-week outpatient supervised exercise and education program. No morbidity or mortality occurred during the program, and most patients achieved a substantial improvement in exercise capacity. During a follow-up interval of a mean of 29.7 +/- 13.0 months, four patients died, an annualized mortality of 8 +/- 4%. The outcome of cardiac rehabilitation was assessed 19.1 +/- 4.4 months after completion of the supervised program. Of the 16 survivors, all of whom had been fully employed before their most recent myocardial infarction, 9 (56%) had returned to full-time work, 6 (38%) were medically disabled, and 1 was retired (age 73 years) but fully active. Of the 16 survivors, 13 (81%) completed a questionnaire about their perceptions of their current quality of life. Of the 13 patients, 12 (92%) had continued to exercise regularly. Four patients (31%) reported the ability to perform all desired activities without symptoms, whereas nine patients (69%) noted some impairment in their functional capacity. Thus, in this group of patients with profound left ventricular dysfunction, the rehabilitation potential, as evidenced by return to productive employment and the ability to perform desired activities-including exercise training-was generally favorable.     

Natural history of radiculopathy

Radicular pain is a frequent complaint of patients presenting to outpatient primary care and musculoskeletal clinics. Most cases of radiculopathy are self-limiting, and symptoms resolve over the course of weeks to months. There is spontaneous resolution of disc herniations, and clinical improvement correlates with morphologic resolution. Knowledge of the natural history of radiculopathy is crucial for the health care provider to appropriately counsel and treat patients with this disorder. Although each patient should be managed individually, the favorable prognosis of radiculopathy based on the natural history supports a conservative approach for the initial weeks to months for most patients.     

Gait training of patients after stroke using an electromechanical gait trainer combined with simultaneous functional electrical stimulation

BACKGROUND AND PURPOSE: This case report describes the implementation of gait training intervention that used an electromechanical gait trainer with simultaneous functional electrical stimulation (FES) for 2 patients with acute ischemic stroke. CASE DESCRIPTION: Two individuals with post-stroke hemiplegia of less than 6 weeks' duration participated in a 4-week gait training program as an adjunct to physical therapy received at a hospital. After the 4-week intervention, both patients were discharged from the hospital, and they returned after 6 months for a follow-up evaluation. OUTCOMES: By the end of the 4-week intervention, both patients had shown improvements in scores on the Barthel Index, Berg Balance Scale, Functional Ambulation Categories Scale, 5-m timed walking test, and Motricity Index. In the 6-month follow-up evaluation, both patients continued to have improvements in all outcome measures. DISCUSSION: This case report shows that, following the use of an electromechanical gait trainer simultaneously with FES, patients after acute stroke had improvements in gait performance, functional activities, balance, and motor control in the long term.     

Regression of herniated nucleus pulposus: two patients with lumbar radiculopathy

Thirty percent to 95% of patients with lumbar radiculopathy secondary to a bulging or herniated disc improve to a pain-free and functional level with nonsurgical treatment. What happens to the herniated disc material as this improvement occurs is unclear. We present two patients with lumbar radiculopathy documented by physical examination and electrodiagnostic testing. Both patients had herniated disc material at the L5 to S1 level on computed tomography (CT) scans corresponding to the side and level of their lesion on physical examination and electrodiagnostic testing. In both instances, the radiculopathy resolved with conservative treatment. CT scans were repeated in three months on one patient and four months on the other. The scans showed major resolution of the herniated disc material in both patients. These two cases demonstrate that in some patients with proven radiculopathy secondary to herniated nucleus pulposus, the herniated disc material will no longer be visible on CT scan and is presumed to resorb as the symptoms abate.     

Group modified constraint-induced movement therapy (mCIMT) in a clinical setting

Purpose: We evaluated the effectiveness of a modified constraint-induced movement therapy (mCIMT) program delivered in a group format. Methods: Thirteen subacute or chronic stroke and two subacute brain injured participants attended a group mCIMT program for 3.5 h daily for 10 treatment days. The groups consisted of three participants supervised by two staff. Motor recovery, functional arm use, and participation were evaluated by an independent assessor at five time points (baseline, immediately preprogram, immediately postprogram, 1 and 3-month postprogram). Results:Participants achieved statistical and clinically significant improvements in motor recovery (Wolf Motor Function Test), functional use (Motor Activity Log) and participation (Canadian Occupational Performance Measure). These improvements were maintained over a 3-month follow-up period. Conclusion: Group delivery of mCIMT produces meaningful results and is a potentially effective way of extending availability of this program without placing overwhelming demands on health care resources.

Implications for Rehabilitation

• Constraint-induced movement therapy (CIMT) is an effective treatment for upper extremity weakness as a result of stroke or brain injury.

• Development of CIMT programs in a clinical setting have been limited by the heavy demands it places on personnel, space and equipment

• A clinically based group modified CIMT (mCIMT) program with stroke and brain injury survivors showed statistically significant and clinically relevant improvements in motor recovery, functional use, and participation.

• Group delivery of mCIMT can be an effective way of extending availability of this program without placing overwhelming demands on hospital resources.

     

An application of upper-extremity constraint-induced movement therapy in a patient with subacute stroke.

BACKGROUND AND PURPOSE: The purpose of this case report is to demonstrate the application of constraint-induced movement therapy with an individual with upper-extremity hemiparesis within 4 months after sustaining a cerebrovascular accident (stroke). Such patients often fail to develop full potential use of their affected upper extremity, perhaps due to a "learned nonuse phenomenon." CASE DESCRIPTION: The patient was a 61-year-old woman with right-sided hemiparesis resulting from an ischemic lacunar infarct in the posterior limb of the left internal capsule. The patient's less-involved hand was constrained in a mitten so that she could not use the hand during waking hours, except for bathing and toileting. On each weekday of the 14-day intervention period, the patient spent 6 hours being supervised while performing tasks using the paretic upper extremity. Pretreatment, posttreatment, and 3-month follow-up outcome measures included the Wolf Motor Function Test and the Motor Activity Log (MAL). OUTCOMES: For the Wolf Motor Function Test, both the mean and median times to complete 16 tasks improved from pretreatment to posttreatment and from posttreatment to follow-up. Results of the MAL indicated an improved self-report of both "how well" and "how much" the patient used her affected limb in 30 specified daily tasks. These improvements persisted to the follow-up. DISCUSSION: Two weeks of constraining the unaffected limb, coupled with practice of functional movements of the impaired limb, may be an effective method for restoring motor function within a few months after cerebral insult. Encouraging improvements such as these strongly suggest the need for a group design that would explore this type of intervention in more detail.
