The Association of Balance, Fear of Falling, and Daily Activities With Drug Phases and Severity of Disease in Patients With Parkinson
Introduction: In the elderly, functional balance, fear of falling, and independence in daily living activities are interrelated; however, this relationship may change under the influence of drug phase and the severity of disease in individuals with idiopathic Parkinson disease. This study aimed to investigate the association of functional balance, fear of falling, and independence in the Activities of Daily Living (ADL) with the drug on- and drug off-phases. Methods: A total of 140 patients with Parkinson disease (age: Mean±SD; 60.51±12.32 y) were evaluated in terms of their functional balance, fear of falling, and independence in their daily activities by the Berg Balance Scale (BBS), Fall Efficacy Scale-International (FES-I), and Unified Parkinson Disease Rating Scale-ADL (UPDRS-ADL), respectively, in drug on- and drug off-phases. The Hoehn and Yahr scale recorded global disease rating. The Spearman coefficient, Kruskal-Wallis, and Mann-Whitney tests were used to find out whether the distribution of scale scores differs with regard to functional balance or disease severity. Results: A strong correlation was found between the functional balance, fear of falling, and independence in ADL with both drug phases. The results also showed the significant difference in the distribution of the FES-I and UPDRS-ADL scores with regard to functional balance (except independence in ADL in drug off-phase). Also, the distribution of the scores of BBS, FES-I, and UPDRS-ADL showed significant differences with regard to disease severity. Conclusion: The study showed a strong correlation between functional balance, fear of falling, and independence in ADL that can be affected by the drug phase and severity of the disease. However, more studies are needed to understand this relationship precisely.This work was supported by the Student Research Committee in Iran University of Medical Sciences, Tehran, Iran.S
Evaluation of Chest Wall Motions by Optoelectronic Plethysmography in Scoliosis Patient: A Case Study
Objectives: This study investigates the chest wall motions and estimates respiratory volumes in a patient with scoliosis compared to a healthy person using the optoelectronic plethysmography method in a sitting position.
Methods: In this research, a scoliosis patient and a healthy individual comprised two subjects. Each person’s upper, middle, and lower chest movement in a seated position was measured using optoelectronic plethysmography.
Results: The changes in respiratory volumes of the middle and lower parts of the chest in patients with scoliosis are more than those of a healthy person during quiet breathing. Moreover, the changes in the upper, middle, and lower parts of the chest in the healthy person are also more than those of the subject with scoliosis during deep breathing.
Discussion: Optoelectronic plethysmography is a noninvasive method to evaluate chest wall movements, respiratory system function, and volumes with fewer limitations than other methods of evaluating respiratory function
A Comparison of Foot Plantar Pressure in Badminton Players with Normal and High-Arched Feet during the Two-Way Lunge
Background: Compared to the individuals with a normal arch structure, those
with high or low arch can be at an increased risk of overuse injuries. The risk
of overuse injury among athletes is high due, in part, to the repeated loading
of the lower extremities. The current study aimed to determine if foot type
(high-arched or normal) results in differences in plantar pressure during two
badminton-specific movements (right-reverse lunge and right-lateral lunge).
Methods: Twenty badminton players (10 with normal feet and 10 with higharched
feet) completed five trials in both right-reverse and right-lateral lunge,
while in-shoe pressure data were collected at 100 Hz. The peak pressure and
mean pressure were analyzed among the subjects for five major anatomical
regions of the foot, using the independent t test in SPSS version 20. The foot type
was determined by the foot posture index (FPI) (α<0.05).
Results: Results showed that the plantar pressure characteristics of normal and
high-arched feet were different; such that in high-arched feet, as compared to
normal subjects, there were significantly fewer pressure strikes in the medial
(P=0.010) and lateral (P=0.002) mid-foot in right-reverse lunge and this was
significantly higher in forefoot (P=0.003) and toes (P=0.010). However, the
peak (P=0.157) and mean (P=0.104) pressure in the heel was higher but not
significant. In the right- lateral lunge, we found statistically lower peak pressure
stroke for the lateral mid-foot (P=0.010) and forefoot (P=0.011); however, the
mean pressure was lower in the lateral (P=0.010) and medial (P=0.040) mid-foot
and forefoot (P=0.120), although it was not significant in the forefoot.
Conclusion: Results showed that the medial longitudinal arch of the foot might
cause pressure differences in the feet among the players with normal and higharched
feet. As the results demonstrated, in high-arched feet, there are some regions
where plantar pressure is higher and some where it is lower. Therefore, in order
to prevent the badminton players from suffering probable foot injuries, attention
should be paid to the compatibility of the insole/shoe and the medial longitudinal
arch and other areas of the foot that suffer more pressures than normal subjects.
