It is hypothesized that when threat to balance (narrowed base of support, perturbation, loss of vision or proprioception) occurs, rapid responses must be engaged to maintain postural stability. Lower limb muscle power (force x velocity of shortening) seems to be more important than muscle strength correlating with balance deficit. Environmental factors (uneven terrain, slippery surface, barriers).Poor footwear (too high or too low heeled shoes).knee instability from osteoarthritis, painful foot conditions) PNS disorders: polyradiculopathy, ganglionopathy, peripheral neuropathy, myopathy.CNS disorders: Stroke, Parkinson’s disease, cervical myelopathy, hydrocephalus, vitamin B12 deficiency, cerebellar degeneration.Specific neurological (central and peripheral) and musculoskeletal disorders.Reduced central integrative processing and cognitive ability (e.g.Poor sensory input (visual acuity, reduced vestibular function).Limited range of motion of lower limb joints (e.g.hip abductor, knee extensor/flexor, ankle dorsiflexors) Etiology/patho-anatomy/physiologyīalance is maintained through a complex process involving sensory detection of body motions, integration of sensorimotor information within the central nervous system, and execution of appropriate musculoskeletal responses.Ĭontributing Factors for Balance Impairment (Diagram 1) areĪssessment and Treatment of Balance Impairments-Diagram 1 attention, reaction time) to work effectively. With aging, even normal individuals show increased truncal sway and reduced postural control due to change in the individual system as well as central ability to integrate these systems (e.g. Maintaining normal balance requires multiple systems (somatosensory, vestibular, visual, musculoskeletal system, and cognition) working in integrative fashion, and the disorders affecting one or more of these systems may lead to impaired balance. Static balance involves the ability to maintain a stable position, while dynamic balance is the ability to maintain postural stability and orientation while individual move from one position to another. ![]() It is unclear how long the strike will last or when an agreement will be reached.Balance, also known as postural control, is the ability to maintain, attain, or correct the center of mass in relation to the base of support 1 and it is necessary for successful daily life tasks. Scripted series might have to cut or delay their seasons. ![]() The strike has brought late-night shows to an immediate halt, and Saturday Night Live could also go without airing this weekend. Also, writers are seeing little to no residual fees for streaming shows since streaming doesn’t utilize syndication rules. Writers have cited that streaming shows run fewer episodes than broadcast, which makes income unstable. The guild said, “The companies have used the transition to streaming to cut writer pay and separate writing from production, worsening working conditions for series writers at all levels.” While writers are “working at a minimum regardless of experience,” TV and film executives have seen their salaries increase. Guild members are looking for pay increases and changes to the current business model that makes it tough for writers to earn a living, citing streaming platforms decreasing median writer-producer pay. As Shadow and Act have also reported, several scripted series have been cut mid or post-production as networks with streaming components, like Showtime and HBO, fall under new leadership. ![]() The proposals are probably a way the guild hoped Hollywood studios would avail the worries of writers who are facing increasing uphill battles against AI, the increase of streaming programming and the downward trajectory of broadcast viewing. The Alliance of Motion Pictures and Television Producers said in a statement that their offer included “generous increases in compensation for writers,” but the studios failed to agree on the Writers Guild’s proposals that would make it mandatory “to staff television shows with a certain number of writers for a specific period of time, ‘whether needed or not,'” according to NBC News.
