Starting my learning journey by Michelle Ng

Frequency of going outdoors.

michellengnyp — 2017-08-25 02:14:37 UTC

When people age, and become more frail, they decrease their frequency of going outdoors. (Kono, Kai, Sakato, & Rubenstein, 2007)
if the frequency of going outdoors increase, they remain more highly functional, socially active and less depressed.

Requirements of going outdoors/community ambulation:

michellengnyp — 2017-08-25 02:17:23 UTC

Adequate physical and cognitive abilities. it acts as a motivation stimulation to their daily life.
Successful mobility depends on skills of the individual, requirements of the task, & challenges of the environment.

Reasons for reduce frequency/not going outdoors:

michellengnyp — 2017-08-25 02:26:38 UTC

1. Poor socioeconomic status, MS conditions, slow walking speed, Environment (presence of poor street conditions, hills, noisy traffic)

2. Fear of moving outdoors increased risk of developing walking difficulties in long term (Rantakokko et al., 2009).
3. Fear of falling appears to reduce the spatial area that an individual moves through in daily life (called life-space) (Auais et al., 2017)

3. Older adults who report that they are concerned about their balance complained of difficulty accessing the community (Yang & al, 2011) and will adjust their behaviour by reducing outdoor activities (Wijlhuizen, de Jong, & Hopman-Rock, 2007) which may have profound effects on their participation in society and quality of life (Pound, Gompertz, & Ebrahim, 1998) (Hirvensalo, Rantanen, & Heikkinen, 2000) .

Thoughts...

michellengnyp — 2017-08-25 02:34:20 UTC

Need to explore theory that will look at helping older adults embrace their fear/ concerns.

Questions

michellengnyp — 2017-08-25 02:40:33 UTC

1.What are the primary factors that prevent older adults having difficulty with accessing the community?
If we understand what are these influencing factors, we could treat/ modify these factors to influence the older adults mobility in community. Can these factors be grouped into physical, emotional and behavioral practices?
2. Can we help older adults to ambulate in the community if we teach them how to walk if we use environmental mapping?
3. Can we map training programmes using life space?
4. What are the recommended outcome measures to determine community ambulation?
5. Based on research by Chippendale and Chang (2017),Chippendale and Raveis (2017) older adults with concern of fall use strategies like visual scanning, avoiding distractions, use of rails on stairs and choice of footwear to prevent falls. Can we use these strategies as part of the intervention programme to empower the older adults to encourage community ambulation?
6. What are the strategies that older adults utilize to ambulate in the community safely

Significance of study. Why?

michellengnyp — 2017-08-25 04:55:28 UTC

1. Locomotion often occurs in a complex environment.
When individual encounter challenges, we either avoid or adjust travel path. Challenges: Distance to destination (endurance), stairs & slopes & transition between surfaces (uneven surfaces), varying levels of lighting (vision is important for adaptive locomotion: plans gait modifications & guide locomotion), steering control (turns) (Patla, 2001)
2. Rehabilitation should prepare individuals with limitations to engage in meaningful activities, be physically active to reduce risk of non-communicable diseases
3. May address the older individuals' concern about ambulating in the community and protect against loss of functional capacity.
4.Most falls occur when an individual is walking. Walking accounted for 47.3% of all falls outdoors (Li, 2006)
5. Both groups of older women (walkers and non-walkers) experience loss of reserve capacity. Small amounts of outdoor walking offers protection against loss of mobility in the short term and helps to retain reserve capacity in the long term (Barak, Wagenaar, & Holt, 2006)
6. All physiotherapist knows that it is crucial to prepare an individual to transit back into the community seamlessly. However, there is no guideline/protocol to guide newly graduated physiotherapist of what is important to prepare patient for community ambulation
6. To help older adults remain functionally independent in their homes and communities and out of long term nursing care facilities.

Thoughts...

michellengnyp — 2017-08-25 05:04:54 UTC

Training should encompass endurance, varying surfaces, challenges to postural balance,
ability to adjust/ utilise appropriate postural strategies when encountering challenges
Consider methods of monitoring physical activity of the older adults

???

michellengnyp — 2017-08-25 07:06:24 UTC

Because of the variability in comm ambulation, importance of discussion with pt to identify needs

Distance and speed influencing walking

michellengnyp — 2017-08-25 07:09:07 UTC

1. Distance & speed requirements (Sys Review)
Distances for community sites frequented are 16 to 672m on average, cross the street .44 to 1.32m/s.
Sites essential for older adults, drs' offices, banks, drugstores, department stores & supermarkets.
Speed & distance influenced by type of site & pop size
(Salbach et al., 2014)
2. Navigation of different terrains
Ability to increase and decrease speed, make anticipatory and reactive postural adjustments, ability to navigate a combination of task and environmental demands (Oh, 2013) (Patla and Frank 2003)

Demographics of indoor vs outdoor falls

michellengnyp — 2017-08-25 07:26:08 UTC

Indoor falls: participants were older, female and poorer health

Outdoor falls: participants were younger, male and physically active. (Kelsey et al., 2010)

Thoughts....

michellengnyp — 2017-08-25 07:28:03 UTC

For any intervention programmes, it should be catered to the different demographics of the individuals.
If we could find out/understand what are the factors that is preventing outdoor mobility, this could prevent future disability.

Walking

michellengnyp — 2017-08-28 05:41:48 UTC

Walking is a highly skilled motor task. It is gained through motor learning (VanSwearingen & Studenski, 2014)
Why?
1. Body mass are balanced over the moving lower limbs,
2. Body’s center of mass travels outside of the base of support for 80% of each stride,
3. Acceleration and brake forces of each step continually challenge trunk stability,
4. toe clears the ground less than 2.5 cm as the swing limb begins to move forward and drops to 1 cm during mid-swing (Frank & Patla, 2003).

Age related changes

michellengnyp — 2017-08-28 06:01:30 UTC

Changes in sensory, motor & CNS integration of systems that work together to bring about movement during gait.
Sensory changes are decreased visual acuity, somatosensory and proprioception.
Adults used speed appropriate responses immediately following perturbation, but took longer to recover steady-state walking at all speeds and variable inter-limb coordination (Krasovsky, Lamontagne, Feldman, & Levin, 2014)
Changes in biomechanical and neuromuscular factors contribute to a loss of motor skill and increased energy cost of walking (VanSwearingen & Studenski, 2014)
Comfortable gait speed may decline at a rate of 0.2% per year up to age 63, accelerates at 1.6% after age 63 (Alexander, 1996)
Decrease in step and stride length(Krasovsky, Lamontagne, Feldman, & Levin, 2014)
Decrease knee extension (Ostrosky, VanSwearingen, Burdett, & Gee, 1994), hip extension (exaggerated
in fallers) (Kerrigan, Lee, Collins, Riley, & Lipsitz, 2001) and ankle ROM (Krasovsky, Lamontagne, Feldman, & Levin, 2014)

Changes in gait have been related to age, psychological factors, mobility, function and risk of falls

Support for rehabilitation/ different patterns of gait training

michellengnyp — 2017-08-28 06:44:19 UTC

1. Research:

Individuals utilise specific strategies to maintain postural control changes when there are any challenges to balance(Adkin, 2000), (Horak, 2006).
Walking patterns is adjusted to meet the type of balance demands encountered to maximize stability(Shkuratova, Morris, & Huxham, 2004).
Response time appears to be important factor of recovery from tripping if a lowering strategy is used(van den Bogert, Pavol, & Grabiner, 2002)

This implied that postural adjustments and walking patterns are task specific. Therefore, this reiterates the importance that rehabilitation should focus on training using a task-oriented approach.

2. Theory:

Walking skill training allows the brain to relearn and to integrate the sequence and timing of movements during gait through motor learning. Motor learning is associated with plastic changes in the brain. With practice, it allow a series of movements to be sequenced together efficiently and automacity (VanSwearingen & Studenski, 2014).

What I know /found out from reading

michellengnyp — 2017-09-04 02:07:13 UTC

What I do not know /What I want to know? Ideas for research

michellengnyp — 2017-09-04 02:09:11 UTC

Questions:

michellengnyp — 2017-09-04 02:15:45 UTC

Does the inclusion of variation of patterns of gait training reduces the
1. probability indoor and outdoor falls?
2. increases the frequency of outdoor ambulation?
3. Improves the quality of life of older adults?
4. Improves the ability of the older adult to ambulate in the community? (distance, speed, multi-tasking, carrying a load, climb stairs etc)

Questions:

michellengnyp — 2017-09-04 03:30:16 UTC

1. How does these age related changes impact on an older adults ability to ambulate outdoors?
2. Are there any gait differences between someone who have fallen versus someone who have not fallen?
3. What are the strategies that they utilize when they encounter environmental demands? Is there a difference between fallers versus non fallers?

Aim

michellengnyp — 2017-09-04 03:48:31 UTC

Improve an older adults' ability to ambulate in the community if they have fallen/impaired balance

Gait differences of fallers vs. non fallers

michellengnyp — 2017-09-04 04:09:47 UTC

1. Fallers demonstrate reduced walking velocity, cadence, shorter stride and step lengths, reduced single support time during obstacle clearance (Newstead, Walden, & Gitter, 2007)
2. Fallers were unable to increase speed on demand. Study of treadmill walking at progressively faster speeds. Non-fallers completed all trials (highest speed of 1.52m/s), 57% of fallers found this speed incompatible.
3. Further decrease in hip extension (Kerrigan, Lee, Collins, Riley, & Lipsitz, 2001) and ankle plantarflexion movement (Barak, Wagenaar, & Holt, 2006)
4. Increase gait variability (stride to stride variations) (Barak, Wagenaar, & Holt, 2006) (Hausdorff, Rios, & Edelberg, 2001)

Implications

michellengnyp — 2017-09-04 04:16:24 UTC

Outcome measures:
Importance of including temporal-spatial measurements of gait, e.g. walking at various speeds, different task conditions

Mobility disability

michellengnyp — 2017-09-04 08:01:30 UTC

Transitions could occur in both directions between the no-disability,

intermittent-disability, and continuous-disability states

and in one direction from each of these three states to death.
(Gill, Allore, Hardy, & Guo, 2006).
Defined as the need for personal assistance (or inability) to walk one quarter of a mile and to climb a flight of stairs, respectively

Individual factors influencing walking

michellengnyp — 2017-09-04 08:13:48 UTC

Psychological factors:
1.Concern about falling influenced the older adults' walking patterns: shorter steps, decreased cadence & increased time in double support (Delbaere, Sturnieks, Crombez, & Lord, 2009).
2. Participants with lower gait efficacy (measured with gait efficacy scale) appear to approach obstacles of different heights with more caution, slower gait speeds & shorter step lengths (Rosengren, McAuley, & Mihalko, 1998).
3. Community dwelling older adults who perceive their health and balance to be good walked more blocks per week (higher physical activity) (Talkowski, Brach, Studenski, & Newman, 2008)
4. Individuals (19%) with fear of falling tend to avoid activities (Tinetti, De Leon, Doucette, & Baker, 1994) particularly reaching and walking(Delbaere, Crombez, Vanderstraeten, Willems, & Cambier, 2004)
5. Number of falls and affective-cognitive variable(concern about falls) influenced an individual's mobility. Catastrophic beliefs about adverse consequence of falls, creates concerns and lead to restriction in mobility (Delbaere, Crombez, van Haastregt, & Vlaeyen, 2009)
Physiological factors:
1. Physiological falls risk (measured by PPA) was associated with slower waking speed(Delbaere, Sturnieks, Crombez, & Lord, 2009).
2. Older adults with normal walking speed walked more blocks/week(higher physical activity) (Talkowski, Brach, Studenski, & Newman, 2008)

Physiotherapy definitions of mobility

michellengnyp — 2017-09-05 03:11:06 UTC

Independent community ambulator means able to meet the demands of moving in the community.
"limited commun.ity arnbulator is an individual who can safely perform some but not all tasks associated with moving through the environment; ·
"household ambulator," is an individual who can perform the tasks that define mobility within the home environment but is incapable of meeting the demands of mobility outside the home; "nonfunctional ambulator" is an individual who cannot meet the requirements of ambulating within the home environment (Patla & Shumway-Cook, 1999, p. 9)
Consist of mobility (walking) and social component.

What is community ambulation?

michellengnyp — 2017-09-05 03:18:31 UTC

Community ambulation is defined as “independent mobility outside the home, which includes the ability to confidently negotiate uneven terrain, private venues, shopping centres and other public venues,”(Lord, McPherson, McNaugton, Rochester, & Weatherall, 2004, p. 236). It requires the individual to have a higher motor control and adaptable cognition to respond to a range of environment stimuli or simultaneous task(Lord, Weatherall, & Rochester, 2010).

Thoughts

michellengnyp — 2017-09-06 04:19:10 UTC

If we add this as a addition to the Otago Exercise program, safety of training is a concern.

Thoughts

michellengnyp — 2017-09-14 07:09:21 UTC

If we understand what are these influencing factors, we could treat/ modify these factors to influence the older adults mobility in community.
Think about how to map practice routes for clients to practice.
