the effect of different types of focus instructions in parkinson's rehabilitation

Conditions: Parkinson Disease; Cognitive Deficit in Attention; Feedback, Psychological; Gait, Festinating

Summary: parkinson's disease is the most common progressive neurodegenerative movement disorder. common movement impairments in parkinson's include balance and walking difficulties. these impairments lead to falls, increased levels of functional dependency, and a decrease in quality of life. exercise in parkinson's patients improves their functional symptoms in daily life, enhancing both motor and non-motor skills, and consequently increases their quality of life. recently, various additional methods have been developed to increase the effectiveness of exercise in parkinson's rehabilitation and to contribute to motor skills. focus of attention instructions are fundamental concepts in motor function learning. external focus of attention has been shown to facilitate motor function development, reduce postural instability, and improve dual-task walking by being easier to remember. in parkinson's patients who experience freezing phenomena, internal focus of attention instructions enhance walking stability and movement control, thereby reducing the risk of falls. however, there are no studies on the combined focus of attention instructions in parkinson's patients. this study is designed as a randomized controlled, single-blind, prospective trial to examine the effects of a combination of internal and external focus of attention instructions on walking, balance parameters, quality of life, and patient satisfaction levels, taking into account the presence of freezing phenomena in parkinson's patients.

parkinson's disease (pd) is the most common progressive neurodegenerative movement disorder. common movement impairments in parkinson's include balance and walking difficulties. these impairments lead to falls, increased levels of functional dependency, and a decrease in quality of life. such deficits are associated with the acquisition of motor function skills. although pd patients are open to learning, they experience challenges with motor planning. therefore, individuals with pd may require additional training, sensory input, and motor education for the permanence and ease of motor skill acquisition. the difficulties pd patients face with complex commands indicate that they can learn in a feedforward manner, but they show inconsistencies in the use of automatic functions. this inconsistency results in challenges in adapting to variable situations and performing complex activities (like balance and walking). exercise in parkinson's patients improves their functional symptoms in daily life, enhancing both motor and non-motor skills, and consequently increasing their quality of life. recently, various additional methods have been developed to enhance the effectiveness of exercise in parkinson's rehabilitation and to contribute to motor skills. one commonly used method to address deficits in motor behavior is motor learning activities, which involve repetitive movements and ensure continuity. many studies have shown that the concept of focus of attention contributes to the efficiency and learning of various motor functions, particularly balance. individuals with parkinson's are highly receptive to external stimuli, so a focus-based strategy during balance and walking training can improve these skills. focus of attention instructions are fundamental concepts in motor function learning. external focus of attention facilitates motor function development, reduces postural instability, and improves dual-task walking. in parkinson's patients who experience freezing phenomena, internal focus of attention instructions enhance walking stability and movement control, thereby reducing the risk of falls. however, there are no studies on the combined focus of attention instructions in parkinson's patients. this study is designed as a randomized controlled, single-blind, prospective trial to examine the effects of a combination of internal and external focus of attention instructions on walking, balance parameters, quality of life, and patient satisfaction levels, considering the presence of freezing phenomena in parkinson's patients. approximately 48 individuals with parkinson's disease without freezing phenomena will participate in an exercise program for six weeks, three days a week. participants will be randomized into a combined focus group, an external focus group, and a control group. assessments will be repeated at the beginning and end of the six-week exercise program.
