AIM This paper is a report of an interpretive review of qualitative research on how an implantable cardioverter defibrillator affects adult recipients and their significant others. BACKGROUND An implantable cardioverter defibrillator detects pathological cardiac rhythms and automatically converts the rhythm with electrical counter shocks. DATA SOURCES A systematic literature search was conducted for qualitative research papers published between January 1999 and January 2009. PubMed, Medline, ISI Web of Knowledge and CINAHL databases were searched with the following key words: internal defibrillator, implantable defibrillator and qualitative research. REVIEW METHODS Twenty-two papers were included. The critical appraisal skills programme and prompts were used to appraise studies. Thematic analysis and synthesis approaches were used to interpret evidence. FINDINGS People with an implantable cardioverter defibrillator were found to experience physical, psychological and social changes. Shocks produce fear and anxiety, affecting relationships and sexual relations. The use of support groups and the use of the Internet are important in helping adjustment to an implantable cardioverter defibrillator. Womens responses to an implantable cardioverter defibrillator appear different than mens responses and include concerns about physical appearance and relationship issues. Postdischarge follow-up and educational programmes are still underdeveloped. CONCLUSION Patients need additional education, support and follow-up care after hospital discharge. Patients and significant others benefit from collaboration between patient associations and healthcare professional societies. Future research is needed to identify the specific challenges that women recipients face.

Claw toe deformity sometimes leads to dorsiflexion of the metatarsophalangeal joint (MPJ) and plantar flexion of the proximal (PIPJ) and distal interphalangeal (DIPJ) joints. Flexor digitorum longus tendon transfer (FDL) is currently the gold standard for the correction of this problem. Transfer of the flexor digitorum brevis (FDB) has been recently proposed as an alternative method to treat such deformity. The aim of this work is to compare the biomechanical outcome of these two methods by means of finite-element simulation. The results show that the reduction in the dorsal displacement of the proximal phalanx (PP) for the second and third toes were very similar (about 4.3 mm for each intervention), both achieving a significant reduction in MPJ dorsiflexion when compared to no intervention (displacements are reduced by approximately 51%). In the fourth and fifth toes, only a small correction in the deformity was achieved with both the techniques (10% and 7%, respectively). FDB and FDL tendon transfer reduced the stress level when compared with the non-operated pathologic foot (the reduction of stresses for the second and third PP ranged between 20% and 40%). FDB transfer resulted in a more uniform distribution of stress along the entire toe, although differences were small in all cases. These results confirm that both the tendon-transfer techniques are effective in the treatment of claw toe deformity. Therefore, the choice of technique is at the discretion of the surgeon.

The calcaneus is a desirable site for harvesting autologous bone for use in foot surgery. However, fracture of the calcaneus is a serious complication associated with bone harvesting from this site. Currently it is unknown how much bone may be safely harvested from the calcaneus without inducing a fracture. The purpose of this study was to investigate the effect of progressive bone removal from the calcaneus onto the mechanical stress redistribution of the foot, and therefore on the increase in fracture risk. Different loads were applied on the talus to evaluate the calcaneus stress distribution at different situations. Because of the potential increase in mechanical stress in the calcaneus, secondary to contraction of the Achilles tendon, we also evaluated the mechanical behavior properties of the foot with increasing traction force in the Achilles tendon. A three-dimensional (3D) finite element (FE) model developed from CT images obtained from a healthy individual was used to compute displacement, tension and compression stresses in six situations, including intact foot, and five depth of the bone block removed, with a maximum depth of 7.5 mm. The results from these simulations indicated that when the maximum load was applied at the Achilles tendon, the tension stress increased from 42.16 MPa in the intact foot to 86.28 MPa with maximum bone harvesting. Furthermore, as the volume of bone extracted from the calcaneus increases, there is a redistribution of stresses that differs significantly from the intact foot. In fact, although the maximum stress was not significantly affected by increasing the volume of bone harvested-except when increasing the Achilles tendon force-, stresses did increase in areas of the calcaneus is vulnerable to injury, leading to an increase in fracture risk.

Correction of claw or hammer toe deformity can be achieved using various techniques, including proximal interphalangeal joint arthrodesis (PIPJA), flexor digitorum longus tendon transfer (FDLT), and flexor digitorum brevis transfer. PIPJA is the oldest technique, but is associated with significant complications (infection, fracture, delayed union, and nonunion). FDLT eliminates the deformity, but leads to loss of stability during gait. Flexor digitorum brevis tendon transfer (FDBT) seems to be the best surgical alternative, but it is a recent technique with still limited results. In this work, these three techniques have been analyzed by means of the finite-element method and a comparative analysis was done with the aim of extracting advantages and drawbacks. The results show that the best technique for reducing dorsal displacement of the proximal phalanx is PIPJA (2.28 mm versus 2.73 mm for FDLT, and 3.31 mm for FDBT). However, the best technique for reducing stresses on phalanges is FDLT or FDBT (a reduction of approximately 35% regarding the pathologic case versus the increase of 7% for the PIPJA in tensile stresses, and a reduction of approximately 40% versus 25% for the PIPJA in compression stresses). Moreover, the distribution of stresses in the entire phalanx is different for the PIPJA case. These facts could cause problems for patients, in particular, those with pain in the surgical toe.

Background Calcaneal apophysitis (Sever disease) has been reported to be the most common cause of heel pain in athletic children. Objective The study aim was to compare plantar pressure, plantar surface contact area, distribution of body weight across the lower extremities, and prevalence of gastrocnemius ankle equinus and gastrocnemius-soleus ankle equinus (which can cause decreases in ankle dorsiflexion range of motion) in children with and without Sever disease. Design This was a case-control study. Methods Participants were 56 male students enrolled in a soccer academy. Twenty-eight participants had Sever disease (Sever disease group), and 28 participants were healthy (control group). Dynamic and static peak plantar pressures, plantar surface contact area, and body weight distribution were assessed with pedobarography. A goniometer was used to assess gastrocnemius and gastrocnemius-soleus ankle dorsiflexion range of motion. Results Both maximum and average peak pressures and percentages of body weight supported by each heel were significantly higher in the symptomatic feet of participants in the Sever disease group than in the control group. Twenty-six participants with Sever disease but only 8 participants in the control group exhibited bilateral gastrocnemius ankle equinus. Limitations A limitation of the study is that measurements were obtained from participants who were symptomatic. Conclusions Higher heel plantar pressures under dynamic and static conditions appear to be associated with Sever disease. It is unclear, however, whether these higher pressures are a predisposing factor contributing to the disease or a result of the condition. Gastrocnemius ankle equinus also may be a predisposing factor for Sever disease. Further research is needed to identify other biomechanical factors associated with the disease to enhance prevention and treatment strategies.

Determining progress in gait requires a reliable method. However, achieving standard assessment results in the clinical setting can be challenging. Searching for a reliable tool, we tested OptoGait, a tool that has floor-level, high-density photoelectric cells that can be used to determine patterns of spatial-temporal gait on the basis of 19 variables: step length, stride length, distance, total contact time, step time, walking speed, acceleration, progressive step time, cadence, gait cycle, stance phase, swing phase, heel contact phase, flatfoot phase, takeoff phase, single limb support, double limb support, load response phase, and pre-swing phase. The gait of 126 study participants (41 males, 85 females; 27.37±1.77 years) was assessed twice for each participant during 10 episodes of walking on a 10m walkway each 2 weeks apart. Intra-session and inter-session results were compared using data for each foot alone as well as both feet together. All variables resulted in a high consistency except for acceleration. The intra-session data showed substantial agreement; the intra-class correlation coefficient (ICC) ranged from 0.72-0.78 in the heel contact phase, 0.72-0.76 in the load response phase, and 0.76-0.85 in the pre-swing phase and a low SEM. The inter-session data for each foot alone and both feet together showed substantial agreement (0.77-0.79 in the load response phase) and slight agreement for acceleration (0.06-0.22) with a low SEM. Based on these results, we conclude that the OptoGait system can be used with confidence to evaluate spatial-temporal gait except for acceleration and progressive step time assessment.

Abstract Inadequate footwear, painful and hyperkeratotic lesions (HL) are an extremely common problems amongst older people. Such problems increase the risk of falls, hamper mobility, reduction of quality of life, dignity, and ability to remain independent. The etiology of painful and feet conditions is poorly understood. To discover footwear preferences of older people, pain tolerance may favor presence of HL for the use of inadequate footwear in old age. A sample of 100 participants with a mean age of 74.90 ± 7.01 years attended an outpatient clinic where self-reported demographic data, frequency with which they checked their feet were recorded and measurements were taken of foot sensitivity. Additionally, all participants’ shoes were allocated into optimal, adequate, and dangerous categories based on design, structural and safety features, and materials. Only 12% of the sample population checked their feet every day, 37% revealed symptoms of neuropathy, 14% used optimal shoes, and 61% presented HL. In a bivariate analysis, no significant differences were observed. HL are associated with inadequate footwear, loss of sensitivity, and low frequency of foot health checks.Inadequate footwear, painful and hyperkeratotic lesions (HL) are an extremely common problems amongst older people.

Introduction: The use of an improper shoe size is common in older people and is believed to have a detrimental effect on the quality of life related to foot health. The objective is to describe and compare, in a sample of participants, the impact of shoes that fit properly or improperly, as well as analyze the scores related to foot health and health overall. Method: A sample of 64 participants, with a mean age of 75.3±7.9 years, attended an outpatient center where self-report data was recorded, the measurements of the size of the feet and footwear were determined and the scores compared between the group that wears the correct size of shoes and another group of individuals who do not wear the correct size of shoes, using the Spanish version of the Foot Health Status Questionnaire. Results: The group wearing an improper shoe size showed poorer quality of life regarding overall health and specifically foot health. Differences between groups were evaluated using a t-test for independent samples resulting statistically significant (p<0.05) for the dimension of pain, function, footwear, overall foot health, and social function. Conclusion: Inadequate shoe size has a significant negative impact on quality of life related to foot health. The degree of negative impact seems to be associated with age, sex, and body mass index (BMI).

Background and purpose Nonspecific low back pain (LBP) is the most prevalent musculoskeletal condition in various age ranges and is associated with depression. The aim of this study was to determine the Beck Depression Inventory (BDI) scores in participants with nonspecific LBP and no-pain by age distribution. Methods A case–control study was carried out following the Strengthening the Reporting of Observational Studies in Epidemiology criteria. A sample of 332 participants, divided into the following age categories: 19–24 (n=11), 25–39 (n=66), 40–64 (n=90), 65–79 (n=124), and ≥80 (n=41) years was recruited from domiciliary visits and an outpatient clinic. The BDI scores were self-reported in participants with nonspecific acute or subacute (≤3 months) LBP (n=166) and no-pain (n=166). Results The BDI scores, mean ± standard deviation, showed statistically significant differences (p<0.001) between participants with nonspecific acute or subacute LBP (9.590±6.370) and no-pain (5.825±5.113). Significantly higher BDI scores were obtained from participants with nonspecific acute and subacute LBP in those aged 40–64 years (p<0.001; 9.140±6.074 vs 4.700±3.777) and 65–79 years (p<0.001; 10.672±6.126 vs 6.210±5.052). Differences were not significant in younger patients aged 19–24 (p=0.494; 5.000±2.646 vs 8.250±7.498), 25–39 (p=0.138; 5.440±5.245 vs 3.634±4.397), and in those aged ≥80 years (p=0.094; 13.625±6.1331 vs 10.440±5.591). Conclusion Participants with nonspecific acute and subacute LBP present higher BDI depression scores, influenced by age distribution. Specifically, patients in the age range from 40 to 80 years with LBP could require more psychological care in addition to any medical or physical therapy. Nevertheless, physical factors, different outcomes, and larger sample size should be considered in future studies.
