Novel use of a manual therapy technique and management of a patient with peroneal tendinopathy: a case report.

Peroneal tendinopathy is an uncommon but underappreciated source of lateral hindfoot pain and dysfunction. There is a paucity of literature describing optimal intervention for those suffering with pain secondary to peroneal tendinopathy. The purpose of this case report is to describe the evaluation and treatment incorporating manual therapy and therapeutic exercise for a patient diagnosed with peroneal tendinopathy. The patient was a 50 year-old female with a history of chronic lateral ankle pain and whose presentation was consistent with peroneal tendinopathy. Despite attempts to improve pain and function with over-the-counter orthotics, manual therapy to a hypomobile talocrural joint, and strengthening of the peroneal tendons, successful response was not reported until a lateral calcaneal glide was added. Improvement in impairments (pain, talocrural dorsiflexion, unilateral heel raises, and Star Excursion Balance Test) and function (Lower Extremity Functional Scale and Global Rating of Change), were observed over a course of eight visits. The patient was able to return to work and her recreational work out routine without limitations. In conclusion a successful physical therapy intervention for a patient with peroneal tendinopathy included a unique manual therapy technique, the lateral calcaneal glide, in conjunction with other manual therapy techniques and a structured home exercise program.

Association between altered somatosensation, pain, and knee stability in patients with severe knee osteoarthrosis.

OBJECTIVE: To examine the relationship between knee pain, altered somatosensation, and self-reported instability in individuals with knee osteoarthrosis (OA) during a step-up-and-over task. METHODS: Quantitative sensory testing, including mechanical detection threshold (MDT), allodynia, vibration perception threshold, and pressure pain threshold (PPT), was assessed in 16 individuals (mean age, 52 ± 7 y) with knee OA and in 16 age-matched and sex-matched controls. Pain intensity ratings and subjective reports of instability/buckling were recorded at rest and while performing a step-up task, and these findings were correlated with somatosensory measures. RESULTS: In the OA group, all participants reported allodynia on MDT testing. Compared with healthy controls, MDT was significantly increased (P<0.001), and vibration perception threshold was increased (P=0.02) at the medial knee, indicating hypoesthesia. PPT was significantly decreased at the medial joint line (P=0.03) and 12 cm distal (P=0.02). Comparing participants with OA having severe versus mild radiographic changes, PPT was lower at the medial joint line (P<0.01) but not at 12 cm distal. Fourteen (87.5%) participants with knee OA reported pain and instability during the step task as compared with none or 1 (6%) of the controls. On the step task, longer duration of symptoms was associated with increased pain (P=0.02). A moderate correlation between greater self-reported instability and increased vibratory hypoesthesia at the knee (r=-0.633; P=0.01) was demonstrated, suggesting a potential relationship between somatosensory changes and functional deficits. CONCLUSIONS: Severe OA may result in both hyperalgesia and hypoesthesia at the affected knee. Perceived instability during functional tasks may be mediated in part by pain in individuals with knee OA.
