ABSTRACT:
Objectives: This study tested the hypothesis that an
alternative movement learning method, Awareness Through Movement, would
produce improvements in coordination, mobility, economy of movement
and quality of life in older adults.
Methods: A group of 31 older adults was studied using a prospective,
repeated measures control group design. The SF-36 was used to assess
health status - quality of life. Video motion analysis was used to
collect data on walking and on a floor to stand transfer movement.
Results: Coordination of the transfer movement improved significantly
in the experimental group. Vitality and mental health scores also improved
significantly in this group. Interesting differences between young-old
and old-old changes were observed.
Conclusions: Awareness Through Movement may be an additional effective
method for pursuing the objectives of Healthy People 2010.
Introduction
As people age there is increased risk of a variety of problems such
as falling, injury, loss of mobility, social isolation and depression.
The Healthy People 2010 report has placed a new emphasis on quality
of life and overall well being as opposed to longevity.1,2 A variety
of programs involving physical activity are being developed to address
these risks and problems with the goal of improving quality of life.3 In 1949, Moshe Feldenkrais suggested that some of these problems may
be the result of learning less than optimal habits and postural responses
and could be corrected by a process of exploratory relearning of basic
movement skills.4 He developed a method of teaching called Awareness
Through Movement for this purpose.5 This teaching process can be used
with large groups of people and even made available thru broadcast
media.6 Several studies in recent years have documented that use of
Awareness Through Movement can produce improvements in mobility7 and
balance8 in well elderly populations. The objective of this study
was to assess the hypothesis that an Awareness Through Movement training
program would produce improvements in coordination, mobility, economy
of movement and quality of life.
Methods
We studied the question of whether an Awareness Through Movement training
program would improve the coordination and economy of movement and
health status/quality of life in a well elderly population, using a
prospective, pretest – posttest control group design. Active,
healthy adult volunteers between the ages of 60 and 90 who were residents
of a retirement community were recruited to participate in the study.
A letter was placed in residents' mailboxes and a column was written
in a community newspaper inviting residents to an open community dialog
during which there was a presentation and discussion of the project.
Individuals were screened for inclusion criteria including age, ability
to walk independently without an assistive device for 10 minutes, ability
to walk on a treadmill at 2-3 miles per hour, and ability to get up
from the floor without assistance. Individuals were excluded from participation
if they presented with musculoskeletal or neurological problems preventing
independent mobility, had uncontrolled hypertension, a history of falling
related to cardiac problems, orthopedic surgery within the past year
or previous training in the Feldenkrais method of Awareness Through
Movement. All participants meeting the selection criteria were ordered
by age and gender and then alternately assigned to experimental (EXP)
or control (CON) groups. These 2 groups were further stratified by
dividing each equally into a younger and an older age group. All individuals
received medical clearance to participate in the study from a physician.
Prior to screening, all individuals signed a consent form. The study
was approved by the Widener University Committee for the Protection
of Human Subjects and by the Research Review Committee at the Kendall-Crosslands
Retirement Community in Kennett Square, PA.
The study was conducted over a period of 8 days. On day 1, baseline
data was collected from individuals in both groups. On days 4 and 5,
all members of the EXP group participated in a total of 10 hours of
Awareness Through Movement lessons while the CON group went about their
normal daily activities and meetings. On day 8, post intervention data
was collected from both groups.
The Awareness Through Movement Intervention
The ATM classes were conducted in a large carpeted room with lighting
and temperature to comfort so that all individuals in the group could
participate simultaneously. Individuals were seated in straight back
chairs, standing, or lying on the floor on mats depending on the content
of the lesson. Lessons lasted about 45 minutes and were presented by
6 different instructors over the 2-day period. A lesson consists of
a period of movement exploration during which an instructor guides
participants through a process of movement exploration by suggesting
a variety of possible movement alternatives and directing attention
to a range of possible sensory and perceptual experiences. The lesson
may be structured around a simple movement (e.g. rolling to the side)
which is not identified as a goal of the lesson. The movement serves
as a structure for the participant to explore and appreciate a range
of sensory experience and to work with a variety of strategies for
organizing the suggested actions. Ten lessons in all were presented:
1) leg movements sitting in a chair, 2) body image and pelvic movements
sitting in a chair, 3) lengthening of the body in supine, 4) flexion
movements in supine, 5) rotational movements in sidelying, 6) rotational
movements transferring from a chair to standing, 7) sliding the leg
to the side in supine, 8) rolling from supine to sit, 9) rolling from
supine to prone, and 10) standing and walking. There was no lesson
in this sequence that dealt with the problem of coming to standing
from supine, a dependent variable in the study. These lessons were
based on a set of lessons titled “Innovations in Therapeutic
Movement for Older Adults”.9
Outcome Variables and Data Collection Procedures
Outcome data were collected in 4 areas: 1) responses on the SF-36 health
status measure, 2) coordination in performance of a supine to stand
movement, 3) energy consumption in treadmill walking, and 4) subjective
feedback.
1) The SF-36 (ver.2) was administered by interview to all participants
in both pre and post intervention data collection sessions and scored
using the criteria provided by the Medical Outcomes Trust.10,11
2) Assessment of coordination of the supine to stand movement was done
using video data. Participants were asked to perform 4 repetitions
of the movement from a supine position to standing at their normal
pace. The last 3 movements were recorded on video and the path of movement
of the head was analyzed with the PEAK Motion Analysis system (Peak
Performance, Englewood, CO).12,13 Time to complete the movement and
the number of acceleration units which the movement was composed of
were selected as variables describing coordination or skill in the
movement.14
3) Participants were videotaped during the last minute of a 4-minute
treadmill walk at their preferred speed that was determined during
screening. A 10-second video clip was randomly selected from the last
30 seconds of video for data analysis. Average vertical displacement
of the sacrum during walking was determined using the PEAK-5 Motion
Analysis system. The vertical displacement data were used to calculate
a relative measure of energy expenditure.15
4) Subjective feedback about awareness of changes in performance of
selected daily activities was collected from the experimental group
during the post intervention data collection using a written questionnaire.
Data Analysis
A clearer picture of the outcomes emerged by considering the possible impact
of age as a separate variable. The 2x2x2 design used three (intervention groups,
age groups and time) factors with a repeated measure on the factor of time pre
and post intervention.16 A general linear ANOVA model was used with 2 between
subject variables for parametric data from treadmill and supine to stand performance.
To analyze the SF-36 data, which is non-parametric, the data was collapsed across
the age variable and analyzed using Friedman's 2-way ANOVA. All statistical analyses
were conducted using SPSS v10.1.17 Internal consistency of the SF-36 scores was
high as determined by Cronbach's alpha coefficients.18 PEAK 5 video data were
analyzed for average sacral vertical deviation and movement units using software
written in Labview by Michael Coleman.
Results
Forty-four residents expressed interest and agreed to participate in the screening
process. Thirty-two subjects met the selection criteria. After group assignment,
one subject was moved from experimental to control group due to scheduling problems.
Another dropped out of the experimental group for personal reasons. The final
experimental group included 14 individuals: mean age 79 years, mean activity
level19 of 2.7 , mean resting heart rate 69 bpm, mean weight 67 kg, mean walking
speed 165 ft/minute. The final control group included 17 individuals: mean age
77, mean activity level of 2.6, mean resting heart rate 72 bpm, mean weight 68
kg, mean walking speed 187 ft/minute. Differences between group means for all
these characteristics were statistically insignificant except for walking speed.
Ninety-seven percent of participants were white. Participants were between the
ages of 68 and 89. There were 12 men and 19 women. All were well educated, in
good health and living independently, a robust group.20
Table 1 A and B show the outcomes for SF-36 assessment. Two of the 8 SF-36 subscales
showed significant change across the 8-day period of the study. There was a 3-4%
background of improvement in these subscales in the control group. However in
the experimental group the range of change was greater than 8% for the mental
health variable and 12% for the vitality variable.
Table 1C shows the outcome for the assessment of economy of walking on a treadmill.
This variable assesses the up and down movement of the center of mass which is
highly correlated with energy consumption (r = 0.9).15 A decrease in the up and
down movement, a smaller average deviation, reflects less work and therefore
greater economy of movement. We observed a decrease in sacral deviation of about
the same magnitude across time in both experimental and control groups. This
suggests that there is a learning effect occurring with people who do not spend
a lot of time walking on the treadmill. This was in spite of allowing people
to practice a prescribed amount after screening and before the first data collection.
A learning effect may account for some of the change seen in the control group
in the supine to stand task as well.
Table 1 D and E show the outcomes for assessment of the supine to stand task.
Decreasing time of performance is considered an aspect of skill acquisition.21
A higher level of skill in this task has been documented in a normal adult as
compared to an age matched population with multiple sclerosis.12 A decrease in
the number of movement units that make up a complex movement is also considered
to indicate an increase in coordination in performance of that task 14 as we
have observed previously with a population with multiple sclerosis.12 Here we
observed significant changes as an interaction of group x age x time in both
variables. In both measures there is a decrease in the younger group and an increase
in the older group.
The specific categories of subjective feedback (Table 2) were asked about because
they are areas in which people might experience change in behavior as a result
of participating in Awareness Through Movement lessons.13 It is interesting to
note that there was no report of performance becoming worse or more difficult.
Of greatest interest is the fact that 93% of people who participated in Awareness
Through Movement reported that the supine to stand transfer was easier. This
was in spite of the fact that the change observed was equally divided between
those who decreased time and movement units and those who increased time and
movement units. The last two categories, breathing and sleeping, lend reliability
to the subjective data because both of these were areas in which we expected
significant changes based on previous clinical experience and no changes were
reported.
Discussion
It has been shown that perceived control is positively related to health status
in the old/old.22 A primary finding of this study is improvement
of the SF-36 vitality and mental health subscale scores in the experimental group.
We take
this to reflect an increased sense of well being resulting from participation
in Awareness Through Movement. This has been observed previously in work with
people with multiple sclerosis13 and with a well elderly group.23 In
a previous
study with people with multiple sclerosis,24 we observed significant
improvements in balance performance and balance confidence. In a related, unpublished
qualitative
study, (Personal communication, Dominique duShuttle, May 2000, Research meeting)
themes from a focus group suggested that improved sense of well being is related
to two issues: 1) improved physical function and confidence, and 2) an expanded
sense of the choices available in problem solving engendered by the Awareness
Through Movement process.
The supine to stand performance outcomes of the under 78 or "young/old" experimental
group support our hypothesis that use of Awareness Through Movement can improve
coordination. This was also supported by the subjective feedback that the floor
transfer was easier for almost everyone in the experimental group. However the
bifurcation of response seen with the "old/old" (78 and over) group
is puzzling. Possibly people realized an option to move more slowly and carefully
in an activity that would be complex, unfamiliar and difficult for most 80 year
olds. Possibly the learning process was different in the "old/old" group.
It has been suggested that there are differences in implicit learning between
young and old that could account for differences in performance.25,26,27 The
changes observed may be transient due to the newness of the learning.28 Possibly
there were changes in sensory function, biomechanics or the postural control
process requiring a different solution to a similar problem.13,29,30,31
The beneficial effects of exercise on various physiological and psychological
parameters related to maintaining mobility and independence have been well established.3,32,33,34This study suggests that an approach such as Awareness Through Movement, which
improves coordination, vitality, balance and well being may be a useful adjunct
to enable older people to optimize the benefits of exercise and therefore might
be widely used as a preventative as well as a restorative intervention in pursuit
of the objectives of Healthy People 2010.
The population that was studied was not only socioeconomically advantaged but
also generally robust. The available rehabilitation literature suggests it's
effectiveness with other groups;9,24 however, it remains to be determined if
the Awareness Through Movement approach could contribute as much for other populations
which might be less advantaged in a variety of ways.
