Hand-to-hand bioelectrical impedance (HH BIA) is a low-cost method to estimate percent body fat (%BF). The BIA method is consistently reliable, but questions on validity remain. We have observed anecdotally that elbow position can render consistently different measures of %BF while using HH BIA, thus leading to the question: Does elbow angle influence the validity of measures derived using HH BIA? The purpose of this study was to assess the effect of elbow position (i.e., IN=flexed to 90° versus OUT=fully extended) on the reliability of HH BIA on 44 male and 24 female healthy adults (age=21±2 yrs, BMI=23±3). An additional aim was to assess the validity of the HH BIA %BF on a subset of subjects (n=12) using air displacement plethysmography (BOD POD®) as the criterion measure. The IN position was ~4%BF lower than the OUT position for HH BIA (p=0.05, effect size=0.67). Measures of %BF for both trials for the IN [intraclass correlation coefficient (ICC)=0.99, coefficient of variation (CV)=2.99%] and OUT (ICC=0.99, CV=1.48%) conditions were highly reliable. On the subsample, the OUT (18.3±6.7 %BF) position exceeded both the IN (14.5±7.4 %BF) and the BOD POD® (16.1±7.8 %BF) measures (p<0.05); however, IN and BOD POD® measures of %BF did not differ (p=0.21). These findings support that HH BIA is a reliable measure at both elbow positions; however, %BF estimations vary considerably (~4%) with respect to the criterion measure depending on elbow position. The OUT position was found to overestimate criteria %BF. Further research may reveal an optimum elbow angle position for HH BIA estimates of %BF.

Administration of Non-Pharmachologic Intervention in the control of Hypertension among selected volunteer retirees in Awka Metropolis Anambra State Nigeria

Published on: 6th November, 2017

OCLC Number/Unique Identifier: 7286357213

High blood pressure under medical palance is associated with a variety of circulatory diseases, and it has been estimated that over 12% of all deaths in the world is directly or remotely connected with hypertension. It is said that one out of every five persons, can expect to have high blood pressure at one time or the other, during one’s life time. Based on hemodynamic equation, the mean arterial pressure is equal to cardiac out-put, times resistance (p means=Q x R). Hence hypertension is usually as a result of either an increased cardiac output and/or an increased resistance. The most common form of high blood pressure in humans is called “essential hypertension”, while is said to have no known cause. However this research aims at showing how a 12-week moderate exercise with bicycle egometer (i.e., use of non-pharmacologic approach to reduce the resting heart rate and blood pressure of 6 volunteer retired civil servants from Anambra state civil service and 6 retired academic staff of Nnamdi Azikiwe university in Awka. The paired T-test analysis of data obtained revealed a statistical significant effect of the moderate 12-week exercise on bicycle egometer, on the resting heart rate and blood pressure of the experimental group of the respondents. Hence it could be concluded that the administration of moderate exercise on bicycle egometer could be an effective use of non-pharmacologic intervention in the control and prevention of high blood pressure or hypertension among the elderly.

OCLC Number/Unique Identifier: 7317653930

Osteoarthritis of the hand is a chronic condition that involves hand joints, but receives less attention. Few studies have investigated the use of ultrasound therapy and laser therapy for the treatment of hand osteoarthritis. The objective was to evaluate the effect of the conjugated treatment of therapeutic ultrasound and laser therapy on the pain and joint function of a patient with hand osteoarthritis. The is case of a woman, 57 years old, with a diagnosis of osteoarthritis on hand for 3 years, presenting constant pain and worsening after manual activities. The pain and function were evaluated, respectively, by Visual Analog Scale (VAS) and Australian Canadian Osteoarthritis Hand Index questionnaire (AUSCAN). After 12 sessions using ultrasound and laser therapy application, there was an expressive improvement in the pain and functional indexes of the patient. The combined application of therapeutic ultrasound and laser therapy, through the unified field action of the therapies used, proved to be efficient in reducing pain and improving the functionality.

Published on: 3rd November, 2017

OCLC Number/Unique Identifier: 7286355386

The research investigated the perception of nutrition and exercise as a tool in controlling Cardiovascular Diseases (CVDs) among elderly civil servants in Anambra State of Nigeria. A total of 250 respondents comprising 150 elderly academic staff Nnamdi Azikiwe University Awka and 100 senior civil servants in the Anambra state civil service, who willingly, volunteered to participate in the study. Their ages ranged between 55-65 years purposively selected. The instrument for data collection was a self-structured questionnaire, with a reliability value of 0.73 using the test retest method. All data collected were subjected to descriptive statistics of frequency, percentages and chi square tested at 0.05 level of significance. Findings from the study showed that nutrition (diet) and exercise have significant effect in the prevention/control of (CVDs) among the elderly. It is therefore recommended that at the civil service secretariats, universities and other establishments/parastatals, should establish high standard eateries (restaurants) where qualified caterers, would regularly provide nutritious diet, at subsidized rate for workers in this category. In order to enable these class of workers have at least one good meal per day, in addition to a mandatory one- work-free afternoon (2.00pm-4.00pm) for routine/regular physical exercises for these class of workers.

Published on: 27th October, 2017

OCLC Number/Unique Identifier: 7286357077

Case: A 45 year old male, >1 year status post left elbow lateral debridement for lateral epicondylitis, presented with a two week history of a progressive, tender mass on the lateral aspect of his left elbow. MRI showed evidence of a defect in the joint capsule, consistent with the formation of a seroma. The patient underwent revision of the left lateral epicondyle debridement with ECRL/EDC tendon repair and capsular reconstruction. Conclusion: Tendon repair and capsular reconstruction is an effective and successful method for the treatment of a seroma caused by leakage of joint fluid after lateral epicondylar debridement.

Effect of foot posture on foot-specific health-related quality of life

Published on: 10th January, 2018

OCLC Number/Unique Identifier: 7317601185

The purpose of this study was to determine the relationship between Navicular drop (ND) and Hallux valgus (HV) angles and their effects on foot-specific health related quality of life. Sixty female patients with bilateral HV aged between 32-60 participated in this study. The patients with the HV deformity degree of “2” or “3” according to the Manchester scale were included. HV angle were obtained from standing (weight bearing) bilateral antero-posterior radiographs. HV angle (A angle), intermetatarsal angle (B angle), hallux interphalangeal angle (C angle) were measured. Subtalar pronation was measured the navicular drop (ND) test. ND test were performed for both feet and recorded in millimeters. Foot-specific health related quality of life was measured using the Manhester-Oxford Foot Questionnaire (MOFQ). There was a strong positive correlation between the ND qtest and the angles A, B, and C for the right foot (rho=0.749, 0.761 and 0.749 p<0.001, respectively,). There was a strong positive correlation between the MOFQ subscales and the angles A, B, and C for the right foot (p<0.001). There was a strong positive correlation between the MOFQ subscales and the angles A, B, and C for the right foot (p<0.001). In conclusion, there were relationship between ND, HV angular severity and foot-specific health related quality of life. As the HV angular severity increased, there was greater drop in the navicula and reduction in quality of life.

Vertebral pain syndrome and physical performance assessing in older women with vertebral fractures

Published on: 17th October, 2017

OCLC Number/Unique Identifier: 7286344789

The purpose of this study was to assess the peculiarities of vertebral pain syndrome, parameters of physical performance and quality of life indices in women of older age depending on the presence of vertebral fractures (VF). This study was performed with participation of 215 women aged 50-89 years old which were divided into two groups: first one-women without any previous osteoporotic fractures (n=143), second group - patients with VF in thoracic and/or lumbar spine (n=72). The presence and intensity of pain in the thoracic and lumbar spine were evaluated using the 11-component visual analog scale (VAS), physical performance-with following functional tests: 3-, 4- and 15-meter tests (gait speed), static balance (a side-by-side position, a semi-tandem position and a full-tandem position), 8-feet test and «five timed chair stands» (coordination and strength), hand grip strength (by dynamometer), measurement of arterial pressure (systolic and diastolic), heart and respiratory rates, breath holding, chest excursion (mean and on the inhalation and the exhalation), lateral trunk lean, Schober and Thomayer tests. It was demonstrated that the intensity of vertebral pain (pain at the time of investigation, the most common level of pain, pain in the best periods of the disease) and some physical performance tests (lateral trunk lean and chest excursion (mean index, during the inhalation and exhalation), hand grip strength, 15-meter gait speed test and five-repetition sit-to-stand test) are significantly worse in women with VF than corresponding parameters in persons without fractures. It should be taken into account during the assessment of physical performance and development of rehabilitation programs for older age women with vertebral fractures.

Injuries of the shoulder sustained by Surfboard riders

Published on: 9th January, 2018

OCLC Number/Unique Identifier: 7317656813

Background: To determine the spectrum of shoulder pathologies suffered by surfers. Methods: Prospective descriptive study. Surfers with shoulder injuries who were referred to a sub-speciality orthopaedic shoulder private practice situated on the Northern beaches of Sydney (Australia) were recruited over a three-year period. Results: 42 shoulders in 37 subjects were included-12 acute injuries (29.3%), 9 acute on chronic (22%) and 20 chronic injuries. Average age 48 years (range 20-72 years). Seventeen subjects (46%) had manual occupations and 20 subjects (54%) had office-based occupations. Spectrum of pathologies included rotator cuff tendon tears, long head of biceps tendon pathology, labral tears, acromioclavicular and glenohumeral joint osteoarthritis. Discussion: There is a wide spectrum of acute and chronic shoulder injuries sustained by surfers. The most common presentation was for chronic pathology. The average age of 48 suggests that age may play a role in attritional/degenerative change and therefore an increased likelihood of injury.

The effect of cognitive strategies of association and dissociation on central nervous activation: A controlled trial with long distance runners

Published on: 11th October, 2017

OCLC Number/Unique Identifier: 7286431108

The purpose of the present study was to experimentally assess the effect of cognitive strategies of association and dissociation while running on central nervous activation. A total of 30 long distance runners volunteered for the study. The study protocol consisted on three sessions (scheduled in three different days): (1) maximal incremental treadmill test, (2) associative task session, and (3) dissociative task session. The order of sessions 2 and 3 was counterbalanced. During sessions 2 and 3, participants performed a 55 min treadmill run at moderate intensity. Both, associative and dissociative tasks responses were monitoring and recording in real time through dynamic measure tools. Consequently, was possible to have an objective control of the attentional. Results showed a positive session (exercise+attentional task) effect for central nervous activation. The benefits of aerobic exercise at moderate intensity for the performance of self-regulation cognitive tasks are highlighted. The used methodology is proposed as a valid and dynamic option to study cognitions while running in order to overcome the retrospective approach.
