This study aims to examine the effects of percussion therapy on the biomechanics of pickleball movement and muscle activation patterns in recreational pickleball players. It is hypothesized that kinematics and kinetics of pickleball performance improves after 4 weeks of percussion therapy.', 'detailedDescription': 'Pickleball has rapidly increasing its playing population among people with different ages and performance levels. While pickleball is keeping people of all age active, injury prevalence of recreational pickleball players particularly for elderly populations has rapidly become a great concern in health care in recent years. It is crucial not only for individuals who play the sports but also for sports medicine professionals to prevent injuries and assure wellbeing of pickleball players. Percussion therapy with a handheld massage gun has widely utilized both in clinical or sports settings and by individuals as a self-care device, allowing the treatment popular and accessible. While previous research has examined acute effects of percussion therapy, the impacts of percussion therapy on exercise performance are not yet fully understood mainly due to diverse designs, protocols, and qualities of previous studies. Moreover, little is known how biomechanical characteristics (i.e., joint kinematics and kinetics) of sports specific movements of pickleball are altered after the percussion therapy. With Increased demand on pickleball as a recreational exercise, it is of interest in investigating the biomechanical characteristics of pickleball and determining the impacts of percussion therapy on them. The proposed project aims to examine the effects of percussion therapy on the biomechanics of pickleball movement and muscle activation patterns in recreational pickleball players. It is hypothesized that kinematics and kinetics of pickleball performance improves as well as static joint range of motion (ROM) after the percussion therapy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age range: 18 - 80 years old\n* Free from injury in lower extremity for the last 6 months\n* Plays pickleball regularly defined as self-reported participation on at least a weekly basis for a year or more\n\nExclusion Criteria:\n\n\\* Joint injury within previous 6 months'}, 'identificationModule': {'nctId': 'NCT07005934', 'briefTitle': 'Effects of Percussion Therapy on the Biomechanics of Pickleball Movement', 'organization': {'class': 'OTHER', 'fullName': 'Point Loma Nazarene University'}, 'officialTitle': 'Effects of Percussion Therapy on the Biomechanics of Pickleball Movement', 'orgStudyIdInfo': {'id': 'PointLomaNU'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'Control', 'description': 'No percussive therapy will be applied to participants in this group.'}, {'type': 'EXPERIMENTAL', 'label': 'Intervention', 'description': 'Percussive therapy will be applied to participants in this group.', 'interventionNames': ['Device: Theragun Prime']}], 'interventions': [{'name': 'Theragun Prime', 'type': 'DEVICE', 'description': 'Percussion massager', 'armGroupLabels': ['Intervention']}]}, 'contactsLocationsModule': {'locations': [{'zip': '92123', 'city': 'San Diego', 'state': 'California', 'country': 'United States', 'facility': 'PLNU x Padres Biomechanics Laboratory', 'geoPoint': {'lat': 32.71571, 'lon': -117.16472}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'There are no plans to share the data after study completion.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Point Loma Nazarene University', 'class': 'OTHER'}, 'collaborators': [{'name': 'Therabody, Inc.', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Full Professor', 'investigatorFullName': 'Arnel Aguinaldo', 'investigatorAffiliation': 'Point Loma Nazarene University'}}}}
