Background and Purpose: People with facial movement disorders are instructed to perform various facial movements as part of their physical therapy rehabilitation. Automated facial image analysis of both puckering and blowing was used to determine the difference between facial actions for the following movement variables: maximum speed, amplitude, duration, and corresponding asymmetry. : There was a difference between the amplitudes of movement for puckering and blowing.

Discussion and Conclusion: The findings demonstrate that puckering and blowing movements in people with facial movement disorders differ in a manner that is consistent with differences Puckering your lips in people who are healthy.

Puckering your lips

This information may be useful in the assessment of and intervention for facial movement disorders affecting the lower face. A person's face is his or her first form of identification.

Puckering your lips

The face is the physical attribute that distinguishes a person from the rest of the world and is an essential component of how an individual interacts with others, sustains life, and manages his or her environment. People with facial movement disorders report physical function and psychosocial distress related to their physical appearance, difficulty pronouncing specific words or sounds, drinking from a cup, or even chewing food.

Because routine tasks, such as eating or drinking, that depend on healthy facial functioning can be very challenging for people with Puckering your lips movement disorders, improving lip movement and movement control is an important target of intervention. Frequently, the treatment for such Puckering your lips includes facial physical therapy for facial rehabilitation, with the ultimate goal of increasing voluntary movement of the facial muscles. Although treatment programs may differ from therapist to therapist regarding the specific therapeutic approach, many include a series of facial actions for the patient to perform both during the therapy session and as a part of a home exercise program.

One facial muscle, the obicular muscle of the mouth orbicularis orisis responsible for both puckering and blowing facial actions. We ly compared the movements of puckering and blowing in adults without facial nerve impairments. The facial actions were video recorded, digitized, and measured by use of automated facial image analysis. Focused movement instructions may lead to better assessment and better therapy as well as an increase in the understanding of the basic processes of deliberate facial movements in people with facial movement disorders.

Schmidt and colleagues 11 also have found a consistent relationship between the amplitude of movement and the maximum velocity of the lip corner movement during both facial actions.

Puckering your lips

The relationship Puckering your lips been found in studies involving spontaneous movements as well and has been interpreted as evidence of the stereotyped nature of human facial expressions. A consistent relationship between speed and amplitude of movement on both sides of the face has been shown for puckering and blowing in adults who are healthy.

Because of the aforementioned relationship between maximum speed and amplitude in people without facial movement disorders, we expected to find a similar relationship in people with such disorders in the present study. Lip movements on the impaired side of the face, however, may not exhibit the same type of relationship between movement measures. We compared 2 facial actions in different contexts of instructions to determine the facial movement and instructional context producing the greatest facial motion.

On the basis of studies, we expected that puckering facial action, which focuses attention on movement of the lips specifically rather Puckering your lips on the context in which a task is accomplished eg, blowing out a candlewould be smaller in amplitude, smaller in maximum speed, and shorter in duration in people with facial movement disorders. In addition, we expected that puckering facial action would have greater asymmetry of movement than blowing facial action for all 3 measures ie, amplitude, maximum speed, and duration. Subjects were 73 people 43 women and 30 men who had a unilateral facial movement disorder and who were receiving physical therapy at the University of Pittsburgh Facial Nerve Center.

At the time of participation in the present study, all subjects were enrolled in a larger study of psychosocial health and facial nerve disorders FIND study at the University of Pittsburgh. Videotape from 2 subjects was not available; therefore, these subjects were excluded from the study. In total, 5 subjects were excluded from the overall group of FIND subjects. Subjects ranged in age from 18 to 65 years, with a mean age of 43 years. The average length of time since the onset of the facial movement disorder was 25 months. All participants were compensated for their participation in the research project.

After providing informed consent for participation in the study, participants were video recorded while performing a of voluntary facial movements and tasks. Each participant was seated in a chair. Head motion was minimal and was controlled for by the video data processing method described below. Participants were instructed to voluntarily perform several facial actions. These facial actions were performed and video recorded in the context of a facial evaluation that included Puckering your lips facial actions involving upper, middle, and lower facial regions.

Examples of neutral expression and puckering Puckering your lips blowing movements in an individual with facial movement disorder facial Action Unit 0 and facial Action Unit 18, according to the Facial Action Coding System 12 Digital video was exported to an image sequence format by use of Adobe Premiere 6. Thirty video frames per second were captured. Automated Face Image Analysis software was used to track the movement of the lips.

In the AFIA system, the feature points affect only the video-recorded image and are not physically placed on the participant's skin. A study of people with facial movement disorders established very high reliability between the position of traditional physical facial markers on the skin and the position of feature points in the AFIA system.

Puckering your lips

The 10 feature points that capture the movement of the lips are shown in Figure 2. The feature points included in the analyses in this study Puckering your lips the following: both lip corners, 2 points on the left side of the upper lip, 2 points on the right side of the upper lip, 2 points on the left side of the lower lip, and 2 points on the right side of the lower lip.

The middle lip points were excluded from the analysis because the points did not belong to either side of the face. The Lucas-Kanade algorithm for feature point tracking was used to automatically obtain x-y coordinates for the feature points in subsequent frames.

Feature points that capture the movement of the face with Automated Facial Image Analysis software. The displacement of each pixel coordinate r from its initial position x, y was calculated as follows:. In order to facilitate comparisons among participants, values of r were divided by the initial neutral value for the width of the mouth from the left lip corner to the right lip corner.

Proportional values of r were then summed for all feature points tracked on the left side of the mouth to create a composite variable combining movements at all 5 lateral points including the mouth corner. The same process was performed for Puckering your lips points on the right side of the mouth.

From these summed left and right composite proportional variables, onset start and end times were obtained for each side of the mouth during expression. We defined onset duration of the expression as the longest continuous increase in seconds in composite displacement values over the course of the expression. Composite displacement values for the impaired and unimpaired sides of the face were analyzed to obtain values for the amplitude and the maximum speed of initial onset.

The duration of onset also was analyzed for the right and left sides. Amplitude was established by finding the difference between the composite displacement values at the beginning and the end of the defined movement onset period. Maximum speed of onset for impaired and unimpaired sides was established by finding the maximum frame-to-frame difference between the composite displacement values. For determining asymmetry, the differences between impaired and unimpaired values of amplitude, maximum speed, and duration were calculated.

All variables were determined for the facial actions of puckering and blowing. Descriptive statistics were determined for each dependent variable. A repeated-measures analysis for within-participant differences was conducted with facial action puckering or blowing and impairment status impaired or unimpaired as factors.

Amplitude, maximum speed, duration, amplitude asymmetry, maximum speed asymmetry, and duration asymmetry were the outcome measures for the analyses. Correlational analyses Pearson product moment correlation of the relationship between maximum speed and amplitude of movement on both sides of the face impaired and unimpaired were conducted for both puckering and blowing actions, and the proportion of the variance in amplitude ed for by maximum speed was reported as R 2.

Descriptive statistics for the composite movement variables amplitude, maximum speed, and duration of movement were determined Tab. Impairment attributable to unilateral facial movement disorder also affected movement in puckering and blowing. Unilateral facial movement disorder produced a degree of asymmetry in movement for both puckering and blowing actions.

Asymmetry of movement for 3 composite movement variables, however, did not differ between puckering and blowing actions. As in an earlier study of people without facial movement disorders, maximum speed and amplitude of movement were related in both puckering and blowing, although a ificant amount of variance in amplitude remained unexplained by the maximum speed of movement.

Specifically, the response to a request for blowing produced greater facial movement than a response to the request for puckering. Blowing, a facial action in which the participant was instructed to focus on the context, resulted in greater movement than puckering, for which instructions focus attention on the movement of the lips.

Facial impairment affected amplitude of movement, but blowing still produced greater amplitude of movement than puckering, even on the impaired side of the face. Duration was not longer for blowing on either impaired or unimpaired sides of the face, which indicated that people with facial impairment do not take longer to generate greater facial actions involving movements of the orbicularis oris muscle.

Asymmetry was not different between puckering and blowing; the effects of facial impairment were likely to have been greater than any effects of context on asymmetry of facial movement. Although physical therapy for facial nerve disorders is a common intervention, few controlled clinical trials have been carried out to determine Puckering your lips.

One study that did focus on the physical therapy treatment of Bell palsy showed a positive trend between physical therapy and facial function. Ten of the 16 facial actions were deed to improve mouth movement. Further investigation is necessary to determine the effectiveness of contextual and instructions-only approaches. The of the present study may be useful in physical therapy for people with facial nerve disorders. There was a positive relationship between maximum speed and amplitude of movement correlations ranging from.

The relationship was similar to that ly found and was similar on the impaired and unimpaired sides. We concluded that the presence of impairment likely did not affect the relationship of speed and amplitude because relationships between these movement characteristics found in people Puckering your lips unilateral facial movement disorder were similar to those found in a study of healthy puckering and blowing movements.

Because this study focused on 2 particular facial actions, further research Puckering your lips necessary to determine the extent to which the context of instruction influences facial movements. The pattern for a well-learned, externally directed task in which the goal is moving air may differ from the pattern for a well-learned, perhaps internally represented task for the goal of moving the lips. Recruitment of motor units for pucker may be more related to a central estimation based on past Puckering your lips of recruitment of facial motor neurons for the pucker motion, while the blowing task may facilitate recruitment until the task is accomplished, focusing more on the goal of the present movement than a prior representation.

In the presence of a unilateral facial movement disorder, recruitment based on past experience may be inadequate to generate the same amount or pattern of facial movement for the goal of pucker. Clinically, a therapist cannot create a successful therapy regimen based on one facial movement. Although the have important implications, instructions focused on tasks Puckering your lips lip movements to accomplish versus Puckering your lips focused on the lip movement is only one aspect of increasing total facial movements.

Puckering your lips

Perhaps future studies could compare several facial actions with instructions to their nonspecific counterpart. Studies similar to the present investigation may be helpful to determine whether context of instruction impacts movement performance of the entire hemisphere of the motor impairment associated with a facial nerve disorder, or only the movement problems associated with muscles of the lips. Such information may help physical therapists create therapeutic regimes involving facial actions that facilitate greater movement of the face.

In conclusion, more effective physical therapy could lead to increased movement control and potentially lessen psychosocial distress of people with facial movement disorders.
