Up to 50% of patients, however, may be asymptomatic ( Boulton 2005a). It often starts at the distal ends of the longest nerves with a stocking‐glove presentation and moves proximally ( Boulton 2005b). Most patients, however, have both large‐ and small‐nerve fibre damages in DPN of the limbs ( Vinik 2004).ĭPN of the limbs increases with both age and duration of diabetes, and seems more common in those with suboptimal glycaemic control and obesity ( Boulton 2005b Smith 2013). DPN of the limbs may involve large‐fibre nerves (more related to touch, vibration, position perception and muscle control), small‐fibre nerves (more related to thermal perception, pain and autonomic function) ( Vinik 2004) or both. ![]() Typically, it is a chronic, symmetrical and length‐dependent condition, compromising multiple nerves ( Dyck 2011a Tesfaye 2010). In a large cohort of people with DPN in the UK, 7% developed a diabetic foot after one year ( Abbott 1998).ĭPN is largely concerned with the feet and lower limbs, although in some severe cases the hands may also be affected ( Boulton 2005a Boulton 2005b). ![]() A prospective study with 7.5% participants diagnosed with DPN at baseline showed that the prevalence increased to 45% after 25 years of follow‐up ( Pfeifer 1995). Some evidence has shown that the prevalence of DPN among people with diabetes in the UK is estimated to be 50% ( Sugimoto 2000), while the World Health Organization estimate for the UK is 29% ( Wild 2001). Stage 3: late complications of clinical neuropathy Sensory loss is slight, but pain at night common Signs of reduced or absent sensation with absent reflexes No symptoms or numbness/deadness of feet reduced thermal sensitivity painless injury Painless with complete/partial sensory loss Minor sensory signs or even normal peripheral neurological examination May be associated with initiation of glycaemic therapy Journal of Orhtopaedic & Sports Physical Therapy 2012 42(9):760-771.Positive symptomatology (increasing pain at night): burning, shooting, stabbing pains ± pins and needlesĪbsent sensation to several modalities and reduced or absent reflexes The ability of clinical tests to diagnose stress fractures: a systemative review and meta-analysis. Schneiders AG, Sullivan SJ, Hendricks PA et al. Although Doppler Ultrasound seems to be increasingly utilized in musculoskeletal medicine, it is not useful for detecting lower limb stress fractures.ĭo you have leg pain? Do you think it could be a stress fracture? Our clinic doesn’t typically treat stress fractures, but we really like helping people figure out if they might have one. Bone scan or MRI have been established as the best way to detect a stress fracture. X-rays are not the best for detecting stress fractures. Stress fractures are diagnosed with imaging. Surprisingly, the literature shows that there may be some slight validity to this test but it should not be used as a stand-alone diagnostic tool. The theory is that the vibration is sent through the bone from the fork and if there’s a fracture, the vibration in this area would be painful. ![]() The fork is placed on the bone in question and an increase in pain may suggest the presence of a fracture. To perform this test, the practitioner strikes an instrument called a tuning fork on a hard surface (like the bottom of a shoe) to get the instrument vibrating. ![]() Tuning forks are often used in a clinical or field setting to detect the presence of a bone fracture. Unfortunately, there are no reliable clinical tests that can definitively rule this condition in or out. Factors such as training schedule, training surface, footwear, previous injury and overall bone health are some of the many important factors to consider. Suspicion of stress fracture is usually determined during the patient interview. In fact, it affects approximately 20% of runners! 80-95% of stress fractures occur in the lower limbs and the tibia is the most commonly affected bone. A stress fracture is an overuse bone injury that typically affects active people.
