Do the guidelines do what they are supposed to?

The unwritten purpose of the guidelines appears to be to reduce risk to patients of cervical manipulation and to provide legal indemnity to physiotherapists. Do the guidelines achieve this purpose

Prescription of activity for low back pain: What works?

This paper provides evidence-based guidelines for the prescription of activity in the management of non-specific low back pain (NSLBP). The 62 clinical trials published between 1966 and 1997, identified by a search of the Medline and Cinahl databases, were reviewed to provide the basis for the guidelines. The available evidence suggests that physiotherapists should advise patients with acute and sub-acute NSLBP to avoid bed rest and to return to normal activity using time rather than pain as the guide to activity resumption. While structured exercise programs have not been shown to provide a benefit for acute NSLBP, there is strong evidence to support their use for patients with sub-acute and chronic NSLBP and in the prevention of NSLBP

Association between abnormal kinematics and degenerative change in knees of people with chronic anterior cruciate ligament deficiency: a magnetic resonance imaging study

Progressive degeneration of the anterior cruciate ligament (ACL) deficient knee may be partly due to chondral trauma at the time of ACL rupture and repeat episodes of subluxation, but also due to aberrant kinematics altering the wear pattern at the tibiofemoral interface. The hypothesis that altered kinematics, represented by the tibiofemoral contact pattern, would be associated with articular cartilage degeneration in ACL-deficient knees was tested in a cross-sectional study of 23 subjects with a history of > 10 years ACL-deficiency without knee reconstruction. Subjects were aged 31 to 67 years. Eleven were male, 12 were female. Sagittal magnetic resonance imaging (MRI) scans enabled tibiofemoral contact mapping as subjects performed a closed-chain leg-press. Images were acquired at 15 degree intervals from 0 degrees to 90 degrees knee flexion. Articular cartilage degeneration was assessed by diagnostic MRI and where possible, arthroscopy. The ACL-deficient knees had a posterior tibiofemoral contact pattern on the tibial plateau compared to the healthy knees (F(1,171) = 9.2, p = 0.003). The difference appeared to be seen in the medial compartment (F(1,171) = 3.2, p = 0.07), though this failed to reach significance. Articular cartilage degeneration in the medial compartment was related to the variation of the tibiofemoral contact pattern (r = –0.53, p = 0.01). Articular cartilage degeneration was not related to time since injury (r = –0.16, p = 0.65). The association between aberrant kinematics and degenerative change may stimulate thinking on the role of dynamic stability and neuromuscular co-ordination in joint protection

Progressive resistance training and stretching following surgery for breast cancer: study protocol for a randomised controlled trial

BACKGROUND: Currently 1 in 11 women over the age of 60 in Australia are diagnosed with breast cancer. Following treatment, most breast cancer patients are left with shoulder and arm impairments which can impact significantly on quality of life and interfere substantially with activities of daily living. The primary aim of the proposed study is to determine whether upper limb impairments can be prevented by undertaking an exercise program of prolonged stretching and resistance training, commencing soon after surgery. METHODS/DESIGN: We will recruit 180 women who have had surgery for early stage breast cancer to a multicenter single-blind randomized controlled trial. At 4 weeks post surgery, women will be randomly assigned to either an exercise group or a usual care (control) group. Women allocated to the exercise group will perform exercises daily, and will be supervised once a week for 8 weeks. At the end of the 8 weeks, women will be given a home-based training program to continue indefinitely. Women in the usual care group will receive the same care as is now typically provided, i.e. a visit by the physiotherapist and occupational therapist while an inpatient, and receipt of pamphlets. All subjects will be assessed at baseline, 8 weeks, and 6 months later. The primary measure is arm symptoms, derived from a breast cancer specific questionnaire (BR23). In addition, range of motion, strength, swelling, pain and quality of life will be assessed. DISCUSSION: This study will determine whether exercise commencing soon after surgery can prevent secondary problems associated with treatment of breast cancer, and will thus provide the basis for successful rehabilitation and reduction in ongoing problems and health care use. Additionally, it will identify whether strengthening exercises reduce the incidence of arm swelling. TRIAL REGISTRATION: The protocol for this study is registered with the Australian Clinical Trials Registry (ACTRN012606000050550)
