The Relationship

Background: This study assessed the relationship between lower limb hemodynamics and metabolic parameters with walking tolerance in patients with intermittent claudication (IC). Patients and methods: Resting ankle-brachial index (ABI), baseline blood flow (BF), BF response to reactive hyperemia (BFRH), oxygen uptake (VO2), initial claudication distance (ICD) and total walking distance (TWD) were measured in 28 IC patients. Pearson and Spearman correlations were calculated. Results: ABI, baseline BF and BF response to RH did not correlate with ICD or TWD. VO2 at first ventilatory threshold and VO2peak were significantly and positively correlated with ICD (r = 0.41 and 0.54, respectively) and TWD (r = 0.65 and 0.71, respectively). Conclusions: VO2peak and VO2 at first ventilatory threshold, but not ABI, baseline BF and BFHR were associated with walking tolerance in IC patients. These results suggest that VO2 at first ventilatory threshold may be useful to evaluate walking tolerance and improvements in IC patients.

Atherosclerotic Risk Factors

On the occasion of diagnosing a popliteal entrapment syndrome in a 59-year old man with no cardiovascular risk factors, who developed acute ischemic leg pain during long distance running, we give an overview on this entity with emphasis on patients’age. The different types of the popliteal artery compression syndrome are summarized. The diagnostic and therapeutic approaches are discussed. The most important clinical sign of a popliteal entrapment syndrome is the lack of atherosclerotic risk factors in patients with limited walking distance. Not only in young athletes but also in patients more than 50 years old the popliteal entrapment syndrome has to be taken into account.

Abstract. Background: Auricular nerve stimulation has been proven effective in different diseases. We investigated if a conservative therapeutic alternative for claudication in peripheral arterial occlusive disease (PAD) via electroacupuncture of the outer ear can be established. Patients and methods: In this prospective, double-blinded trial an ear acupuncture using an electroacupuncture device was carried out in 40 PAD patients in Fontaine stage IIb. Twenty patients were randomized to the verum group using a fully functional electroacupuncture device, the other 20 patients received a sham device (control group). Per patient, eight cycles (1 cycle = 1 week) of electroacupuncture were performed. The primary endpoint was defined as a significantly more frequent doubling of the absolute walking distance after eight cycles in the verum group compared to controls in a standardized treadmill testing. Secondary endpoints were a significant improvement of the total score of the Walking Impairment Questionnaire (WIQ) as well as improvements in health related quality of life using the Short Form 36 Health Survey (SF-36). Results: There were no differences in baseline characteristics between the two groups. The initial walking distance significantly increased in both groups (verum group [means]: 182 [95 % CI 128–236] meters to 345 [95 % CI 227–463] meters [+ 90 %], p < 0.01; control group [means]: 159 [95 % CI 109–210] meters to 268 [95 % CI 182–366] meters [+ 69 %], p = 0.01). Twelve patients (60 %) in the verum group and five patients (25 %) in controls reached the primary endpoint of doubling walking distance (p = 0.05). The total score of WIQ significantly improved in the verum group (+ 22 %, p = 0.01) but not in controls (+ 8 %, p = 0.56). SF-36 showed significantly improvements in six out of eight categories in the verum group and only in one of eight in controls. Conclusions: Electroacupuncture of the outer ear seems to be an easy-to-use therapeutic option in an age of increasingly invasive and mechanically complex treatments for PAD patients.

Exercise Programmes

The generally accepted first-line treatment in patients with intermittent claudication is risk factor modification, medical treatment and exercise training. In an era of reduced resources, the benefit of any further invasive intervention must be weighted against best conservative therapy for patients with claudication. According to some recent trials an integrative therapeutic concept combining best conservative treatment - including (supervised) exercise therapy - with endovascular therapy gives the best midterm results concerning walking distance and health-related quality of life. The improved mid- and long-term patency rate with use of modern technology further supports this concept. The conservative and interventional treatment strategy are more complimentary than competitive. The current main challenge is to overcome the economic barriers concerning the availability of exercise programmes.

SummaryA double-blind, placebo-controlled randomized study with BAY U3405, a specific thromboxane A2 (TX A2) receptor blocker, was performed in patients suffering from severe stade II limb arteriopathy. BAY U3405 or placebo was administered in 16 patients at 20 mg four times a day (from day 1 to day 3). Hemostatic studies were done before therapy, and on day 2 and day 3 under therapy. On day 3, BAY U3405 was shown to induce a highly statistically significant decrease of the velocity and the intensity of the aggregations mediated by arachidonic acid (56 ± 37% for the velocity, 58 ± 26% for the intensity) or by U46619 endoperoxide analogue (36 ± 35% for the velocity, 37 ± 27% for the intensity). Similar results were already observed on day 2. By contrast, such a decrease was not noticed with ADP mediated platelet aggregation. Furthermore, plasma levels of betathrombo-globulin and platelet factor 4 remained unchanged. Peripheral hemodynamic parameters were also studied. The peripheral blood flow was measured using a Doppler ultrasound; the pain free walking distance and the total walking ability distance were determined under standardized conditions on a treadmill. These last two parameters show a trend to improvement which nevertheless was not statistically significant. All together these results encourage further in vivo studies using BAY U3405 or related compounds on a long-term administration.

Transit stations are generally well known as nodes of spaces where percentage of people walking are relatively high. The issue is do more planning is actually given to create walkability. Creating walking led transit stations involves planning of walking distance, providing facilities like pathways, toilets, seating and lighting. On the other hand, creating walking led transit station for women uncover a new epitome. Walking becomes one of the most important forms of mobility for women in developing countries nowadays. Encouraging women to use public transportation is not just about another effort to promote the use of public transportation but also another great endeavour to reduce numbers of traffic on the road. This also means, creating an effort to control accidents rate, reducing carbon emission, improving health and eventually, developing the quality of life. Hence, in this paper, we sought first to find out the factors that motivate women to walk at transit stations in Malaysia. A questionnaire survey with 562 female user of Light Railway Transit (LRT) was conducted at LRT stations along Kelana Jaya Line. Both built and non-built environment characteristics, particularly distance, safety and facilities were found as factors that are consistently associated with women walkability. With these findings, the paper highlights the criteria  which are needed to create and make betterment of transit stations not just for women but also for walkability in general.

Lower Back

Gridhrasi (Sciatica) is a disorder in which low back pain is found, that spreads through the hip, to the back of the thigh and down the inside of the leg. Mechanical low back pain (LBP) remains the second most common symptom related reason for seeing a physician. 85% of total population will experience an episode of mechanical LBP at some point during their lifetime. Fortunately, the LBP resolves for the vast majority within 2-4 weeks. There are many causes for low back pain, however true sciatica is a symptom of inflammation or compression of the sciatica nerve. The sciatica nerve carries impulses between nerve roots in the lower back and the muscles and nerve of the buttocks, thighs and lower legs. Compression of a nerve root often occurs as a result of damage to one of the discs between the vertebrae. In some cases, sciatic pain radiate from other nerves in the body. This is called referred pain. Pain associated with sciatica often is severe, sharp and shooting. It may be accompanied by other symptom, such as numbness, tingling, weakness and sensitivity to touch. There is only conservative treatment giving short term relief in pain or surgical intervention with side effect. But these are not successful and therefore those who are suffering from this are always in search of result oriented remedy. Walking distance and SLR test were taken for assessment parameter, VAS score was adopted for pain. Before treatment patient was not able to walk even 4 to 5 steps due to severe pain, was brought on stretcher and his SLR was 30° of right side. After 22 days of treatment he was able to walk up to 500 meters without any difficulty, SLR was changed to 60° and patient had got 80 % relief in pain. This case report showed that Ayurvedic protocol is potent and safe in the treatment of Gridhrasi.
