Filter by:In spite that variable techniques for lumbar MBRF exists, the tunnel vision technique is widely recommended for exact radiofrequency needle placement. However, this method uses the concept of a steep caudocephalad axial tilt of the fluoroscopy beam, which result in unusual appearance of vertebral structures and a long distance from skin to the target site. In our institution, therefore, the investigators have used a modified method that is easy and safe to place RF needle parallel to the lumbar medial branch in oblique fluoroscopic view. Accordingly, our objectives were to evaluate our modified technique for lumbar MBRF, comparing with the tunnel vision technique, and additionally to assess complications with respect to these two techniques.
This is a prospective, randomized, double-blind, placebo-controlled study. In an initial phase, 100 patients with chronic low back pain will be included in this study. The patients will be recruited through magazines and newspapers to take part in a screening for treatment of low back pain. This screening will involve the evaluation of data such as history and physical examination to classify the patient in the group of nonspecific low back pain, excluding patients with neurological alterations and the so-called Red-Flags. Procedures After the initial screening the patients will undergo diagnostic blocks of the medial branch of lumbar vertebrae L2, L3, L4 , L5 and of the first sacral vertebra (S1) with lidocaine and control with distilled water. The patients that present more than 50% of pain improvement, evaluated by the Likert scale after 30 minutes will form the study group, while the patients that do not present pain improvement with lidocaine or that present pain improvement with distilled water will be excluded. The medial branch block consists of the insertion of a 90mm, 25-gauge needle through the skin with radioscopic control up to the medial branch topography. Infusion of 1ml of 2% lidocaine should be performed in each medial branch of the abovementioned vertebrae. Control is executed in the same manner yet with infusion of 1ml of distilled water. Through the use of the diagnostic block we will have 40 patients selected for the second phase of the study. Once defined the study group should be evaluated before the procedure through the Oswestry, Roland Morris, SF-36 and VAS questionnaires. In the second phase of the study the patients will be randomized. The random division into two groups will be performed through a computerized program of random numbers. The randomization result will be kept in matt sealed envelopes to guarantee secrecy of the allocation. The neurolysis procedure will be carried out in the first group, consisting of 20 patients, and the placebo or sham procedure with the second group, also with 20 patients. The neurolysis procedure will be carried out under sterile conditions, with the patient lying prone and with the neurotome insertion sites anesthetized with 2ml of 1% lidocaine. The neurotome (Smith & Nephew - RF) will be used for the procedure. The neurotome is a radiofrequency apparatus mounted on a 10cm electrode type 22 needle with a 5mm exposure tip. The neurotome should be introduced percutaneously in a manner similar to that adopted in the medial branch block through radioscopic control. The temperature of the electrode after its placement in the correct position is then raised to 80 °C for 90 seconds. Two neurotomies should be performed for each facet, one proximally and the other distally, due to double innervation of each facet. In the patients of the placebo group the procedure will be the same only the temperature of the neurotome will not be raised. This will be performed in a blind manner, as before starting the procedure, the surgeon will show the assistant who turns the device on or not the envelope containing the patient's group (placebo or neurotomy), yet the surgeon will not be informed whether the device has been turned on or not, having to perform the procedure in the same manner in both groups. The patients will then be reevaluated in the first month, 3 months after, 6 months after and 12 months after the procedure. The assessors will not be informed of the group to which the patient belongs, and the same scales performed in the preoperative period will be used here.
Hypothesis: Acupuncture procedure of He's Santong Methods could be an option to treat nonspecific low back pain.
The purpose of this study is 1) to develop an intervention strategy to increase physiotherapists' adherence to evidence-based practice guidelines, 2) to try out this intervention on a small scale to determine what efficacy may be expected from it, and 3) to determine the value of a planned, systematic and theory-based approach that was followed in developing and implementing the intervention.
The general purpose of this pilot study is to determine the effects of a novel exercise intervention (short arc banding (SAB)) on the cross sectional area of lumbar multifidus well as functional outcomes assessments in patients with chronic low back pain.
Low back pain is a usual condition in the western countries and several treatments available for patients with "non-specific low back pain". According to the European guidelines both Brief intervention and exercise/cognitive intervention are effective treatments with regard to pain and function (www.backpaineurope.org), but none have documented effect on return to work. The challenges for health personnel is not cure of the patients back pain, but to build up rehabilitation programs which focus on disability and work incapacity, in patients which are at risk of loosing their work. Dr. P. Loisel, Montreal, Canada", has since 1995 treated patients with back pain according to the "The PREVICAP model - (PREVention of work handICAP)", where the main purpose with work-related program is to prevent prolonged disability and to help patients back to work. Loisel demonstrated that the PREVICAP models accelerated the "return to work" factor by a factor 2.4 (p=0.01). The PREVICAP model had also been evaluated in Amsterdam, by Dr. Anema with the same results. At the Back Clinic, Ullevål University Hospital we are presently involved in a randomized controlled trial after the PREVICAP model, where patients are randomized to Brief intervention including a work-related intervention or usual care. All included patients in both groups, will have a clinical examination by specialist in Physical Medicine and Rehabilitation and advice from a physiotherapist. The current study replaces Brief intervention with an exercise - and a work-related program, so patients with non-specific LBP will be randomized to an exercise and work-related program or usual care. The main purpose of this study - to investigate if rehabilitation programs specifically focusing on the return to work process will reduce sickness absence and disability pension in patients with neck and low back pain. - to assess the work-, individual- and health factors and their interrelationship predicting sickness absence and work disability. - to compare results from the rehabilitation program with results from rehabilitation program in Toronto - to which extent are the patients met by actions from employers and employment services, and does is influence sickness absence and disability. - do these actions represent favourable cost benefit for the work places and the society
The purpose of this study is to compare the therapeutic effects of acupuncture using traditional acupoints and Ashi points with myofascial trigger points superficial dry needling and acupressure, followed by postisometric stretching of the appropriate muscles, in the treatment of patients with chronic mechanical low back pain.
This is a treatment for low back pain using electrical stimulation and laser for 6 weeks.
To administer the MSDR® (Musculoskeletal Disorder Reporting) instrument to document the musculoskeletal profile of patients with chronic low back pain, a prospective, non-randomized, multicenter treatment trial
The purpose of this study is to determine whether transcutaneous electrical nerve stimulation (TENS) delivered via the Empi Select TENS device provides relief of chronic lower back pain.
