Objective: To analyze the effects of a physical therapy intervention on the muscle strength and power of the knee flexors and extensors and functional balance in older adults with Parkinson's disease (PD), according to its clinical severity.
Methods: Forty older adults diagnosed with PD were evaluated before and after 48-week of a basic exercise program (two 20-min sessions a week) to improve functional balance and quadriceps strength. The variables analyzed were: motor aspects of PD, assessed using the Unified Parkinson's Disease Rating Scale (UPDRS); functional mobility; peak torque (PT) and mean power (MP) at the knee flexors and extensors, evaluated using an isokinetic dynamometer (CYBEX®) on both legs at 60°/s (PT) and 240°/s (P); Timed Up and Go (TUG) test; and Tinetti Index. The participants were divided into three groups (GI, GII, GIII) according to their stage (I-III) of PD on the Hoehn and Yahr (H&Y) scale.
Results: Muscle strength and power were greater in GI (PT: 131.14 N/kg ±61.73; P: 102.29 W/kg ±39.16) than in GII and GIII (PT: 82 N/kg ±38.27 and 89.29 N/kg ±68.78; p = 0.047; P: 56.17 W/kg ±31.99 and 68.14 W/kg ±58.18; p = 0.009). In addition, an improvement in functional balance was shown by higher indices after the intervention (p < 0.05).
Conclusion: These findings suggest that training to increase leg strength in the early stages of PD (GI) may benefit this population and this will help in the design of interventions to improve the functional abilities of older adults with PD.

Postural control patterns in gravid women-A systematic review.
PLoS One

Section of Rehabilitation in Orthopaedics, Clinical Rehabilitation Institute, Faculty of Motor Rehabilitation, University of Physical Education, Krakow, Poland.
Background: Postural stability is essential for functional independence in the pregnant population. The contradictions between existing studies and the lack of consistent characteristics in the strategies used by pregnant women for postural control demonstrate the need for further investigation.
Objectives: The aim was to review the available literature on postural strategies throughout pregnancy in both static and dynamic conditions and to provide an assessment of the quality of these studies in terms of methodological issues to identify the reasons for the inconsistencies in findings between research centers.

Background: Unhealthy sleep and exposures to oxidative factors are both associated with poor cognitive performance (PCP), but limited evidence has been found regarding the relationship between sleep patterns and oxidative factor exposures independently or jointly with the risk of PCP.
Methods: We analyzed data from 2249 adults aged ≥60 years in the National Health and Nutrition Examination Survey (NHANES) database (2011-2014). Self-reported questionnaires were used to collect data on sleep duration and sleep disorder, categorizing sleep duration into three groups based on responses: short (6 hours or less per night), normal (7-8 hours per night), or long (9 hours or more per night).

Background: In osteoarthritis quadriceps strength is an important outcome to assess exercise capacity and recovery after arthroplasty. However, its measurement is limited due to lack of time and the need for trained personnel and equipment whose accuracy is verified.
Objectives: To find out the determinants of a reduced quadriceps strength and to establish a score to screen for it.

Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.
