Impact of Footwear and Foot Deformities in patients with Parkinson's disease: A Case-Series Study.

Background: Parkinson's disease (PD) is a common and complex neurological problem. Gait abnormalities are frequent in PD patients, and this increases the risk of falls. However, little is known about foot deformities and footwear in this vulnerable population. Here we investigate whether patients with PD use an appropriate shoe size and know if they have foot deformities or alterations. Methodology: A study of a series of observational descriptive cases in a convenience sample (n = 53 patients) diagnosed with Parkinson's disease. One trained investigator evaluated foot and ankle health. The footwear and foot measurements were obtained using a Brannock device. Results: The podiatric examination and footwear examination detected a high presence of podiatric pathologies and inappropriate footwear. This has a negative impact on the quality of life of these patients. Conclusions: This research detected an elevated number of people with foot deformities or alterations. Moreover, a high proportion of participants with PD wear inadequate footwear (in length, width, or both).

Activation Capacity of the Intrinsic Musculature of the Foot in Handball Athletes with Chronic Ankle Instability.

Chronic ankle instability (CAI) is a common pathology in handball. The role of the intrinsic musculature of the foot in these players in relation to proprioception and stability has not been stablished. The objective of this study was to compare the ultrasound morphology of the heel fat pad of the foot in professional handball players to CAI in healthy players and establish relationships between CAI and physical and psychological variables. The study has been a descriptive observational case-control study in which 20 professional handball male players over 18 years of age were divided into 8 cases (CAI) and 12 controls (healthy). An ultrasound evaluation, the thickness and/or cross-sectional area at rest and the contraction measurement of the Abductor Digiti Minimi, Abductor Hallucis, Flexor Digitorum Brevis and Quadratus Plantae muscles were analyzed. Moreover, the compressibility index of the heel fat pad and the activation of the abdominal wall musculature (ultrasound), the flexion strength of the hallux and lesser toes (dynamometry), the foot functionality (Bristol Foot Score (BFS) questionnaire) and the psychological variables (self-reported questionnaires) were measured. There were no significant differences between the activation capacity values of the foot muscles of healthy and CAI athletes. Significant differences were found between groups regarding the BFS score (p = 0.007), d = 1.404), and significant correlations were also found between hallux flexion strength and lesser toes flexion strength in the total sample. Although there were no differences between the two groups, the identification of the activation pattern of these muscles in handball athletes is essential to the improvement of performance and preventing injuries such as CAI.

Surgical Treatment on Subungual Osteochondromas in Paediatric Feet: A Case Series Study.

Subungual osteochondroma (SO) is an infrequent and non-malignant bone tumour of the distal phalanx, especially prominent in paediatric populations. The aim of this research was to describe a case series of paediatric feet with SO which received surgical treatments. The secondary purpose was to compare these descriptive data by sex distribution. METHODS: Twenty-three paediatric feet with SO confirmed by clinical or radiological features received surgical treatment. Socio-demographic (age, sex, height, weight and BMI) and clinical features (side, location, tumour or pain presence, and nail lift before surgery, as well as recurrence and adverse effects at one month after intervention) were reported. RESULTS: Regarding clinical features before intervention, the most frequent locations of SO were the first toe (86.8%) and the right lower limb (56.5%). In addition, the presence of the tumour, pain and nail lift showed a prevalence of 91.3%, 69.5% and 47% of the study sample, respectively. Considering clinical features at one month after intervention, the most frequent adverse effect was the pain presence (69.5%). In addition, one case (4.4%) presented ulceration. Only one patient (4.4%) suffered from recurrence with a new tumour. There were not statistically significant differences by sex distribution (p > 0.05). CONCLUSIONS: This novel study showed that surgery treatment for SO in paediatric populations presented a very low recurrence degree with minor adverse effects and without differences by sex distribution. Thus, further randomized clinical trials should be carried out in order to determine the effectiveness of this intervention in this special population.

Vibration increases multifidus cross-sectional area versus cryotherapy added to chronic non-insertional Achilles tendinopathy eccentric exercise.

OBJECTIVE: To assess multifidus muscle thickness, cross-sectional area (CSA) and disability in patients with chronic non-insertional Achilles tendinopathy (AT) who developed an eccentric exercise (EE) vibration program compared to an EE program with cryotherapy. DESIGN: Single-blinded randomized clinical trial. SETTING: Outpatient clinic. PARTICIPANTS: A total sample of 61 patients diagnosed with chronic non-insertional AT was recruited and randomly divided into two groups. A group (n = 30) developed the EE program plus vibration and B group (n = 31) received the EE program plus cryotherapy for 12 weeks. Multifidus thickness and CSA were measured at rest and during maximal isometric contraction by ultrasound imaging. The Victorian Institute for Sport Assessment (VISA-A) was used to asses functionality. RESULTS: Multifidus CSA was statistically significant increased (P < 0.05) for the EE vibration program group with respect to EE plus cryotherapy during maximal isometric contraction and at rest at 12-weeks after intervention in individuals with chronic non-insertional AT. Despite both interventions showed differences for the multifidus thickness and AT disability variables over time, there were not between-groups differences. CONCLUSIONS: Authors encourage the use of vibration with respect to cryotherapy added to EE programs in order to enhance multifidus CSA in addition to lower limb functionality in individuals who suffer from chronic non-insertional AT.
