Group exercise for balance in people with Parkinson's disease: a systematic review with meta-analysis.

Background: High-quality evidence shows that exercise helps people with Parkinson's disease improve functional abilities including balance. However, few studies have investigated whether the setting and format through which balance-focused exercise programs are provided matters. This systematic review investigated group exercise compared to individual exercise, and to no-exercise control (CTL), on clinical measures of balance for people with Parkinson's disease.

Participants with restricted dominant shoulder internal rotation range of motion demonstrate no side-to-side difference in humeral head translation; and no difference before and after joint mobilization: a pilot study.

[Purpose] To compare humeral head translation (HHT) during shoulder elevation between dominant and non-dominant shoulders in participants with limited dominant shoulder internal rotation range of motion (ROM). To determine if joint mobilization alters HHT, and if relationships exist between the bicipital forearm angle and HHT. [Participants and Methods] Fifteen (9 female) participants (age 25.

Adaptation in motor strategies for postural control associated with sensory reweighting.

The purpose of this study was to identify and differentiate the motor strategies associated with sensory reweighting adapted during specific sensory integration tasks by healthy young adults. Thirty-six subjects (age range: 21-33 years) performed standing computerized dynamic posturography balance tasks across progressively increasing amplitudes of visual (VIS), somatosensory (SOM) and both (VIS+SOM) systems perturbation conditions. Adaptation in the motor strategy was measured as changes in electromyographic (EMG) activities and joint angles.

Three-Dimensional Spinal Position With and Without Manual Distraction Load Increases Spinal Height.

Objective: The purpose of this study was to investigate if spinal height increases using 3-dimensional (3-D) spinal position with and without manual distraction load and to assess the correlation between spine height changes and degrees of trunk rotation.

Methods: Fifty-six participants were randomly placed in one of two groups: (1) 3-D spinal position with manual distraction load, and (2) without manual distraction load. Spinal height was measured before and after the interventions using a stadiometer.

Kinematic Validation of Postural Sway Measured by Biodex Biosway (Force Plate) and SWAY Balance (Accelerometer) Technology.

Background: The Biodex Biosway® Balance System and SWAY Balance® Mobile smartphone application (SBMA) are portable instruments that assess balance function with force plate and accelerometer technology, respectively. The validity of these indirect clinical measures of postural sway merits investigation.

Purpose: The purpose of this study was to investigate the concurrent validity of standing postural sway measurements by using the portable Biosway and SBMA systems with kinematic measurements of the whole body Center of Mass (COM) derived from a gold-standard reference, a motion capture system.

Can 5 minutes of repetitive prone press-ups and sustained prone press-ups following a period of spinal loading reverse spinal shrinkage?

: The objective of this study is to investigate if sustained and repetitive prone press-ups could reverse decreased spinal height following spinal loading and if there was a correlation between the degree of end range of motion spinal extension and spinal height gains. : Pretest-posttest crossover design is used in this study. : Study was carried out in research laboratory.

Increased spinal height using propped slouched sitting postures: Innovative ways to rehydrate intervertebral discs.

Background: Upright and slouched sitting are frequently adopted postures associated with increased intradiscal pressure, spinal height loss and intervertebral disc pathology.

Objectives: To examine the effects of two sustained propped slouched sitting (PSS) postures on spinal height after a period of trunk loading.

Methods: Thirty-four participants without a history of low back pain (LBP) were recruited (age 24.
