Nerve gliding moves for strength and endurance in athletes
This study tests whether a gentle nerve-stretching technique (neurodynamics) can improve leg strength and endurance in athletes. If you're 18–30, currently active in sports or intense training, and have no recent leg injury or surgery, you may be able to join.
High Point, North CarolinaAges 18–30 - NCT07692126Recruiting
Neck pain and hand strength: core vs shoulder exercises
This study compares two types of exercises to see which better improves hand grip strength and neck pain. If you have had chronic myofascial neck pain (trigger points) in the upper shoulder muscle for over 6 months, this trial may help find which exercise works best for you.
Giza, Giza GovernorateAges 25–45 - NCT07688863Enrolling by invitation
Comparing breathing muscle training methods for heart failure
This trial compares two different types of breathing muscle training to see which works better for people with heart failure and weak breathing muscles. You may join if you have heart failure with reduced pumping ability and are stable overall.
Viña del Mar, ValparaisoAges 18 years+ - NCT06658210Recruiting
Soft tissue massage and pelvic exercises for pelvic scar tissue
This study tests whether gentle massage and pelvic floor exercises can help relieve pain and discomfort from pelvic scar tissue (adhesions) in women who have had a hysterectomy. It may be an option for you if you are married, between 40 and 60, and healthy enough for these treatments.
Lahore, Punjab ProvinceAges 40–60 - NCT06663644Recruiting
Muscle energy technique for short-term low back pain
This study will test whether a gentle hands-on technique called muscle energy can help relieve short-term lower back pain caused by poor posture. If you are an adult between 18 and 40 with new back pain and no other major health issues, this trial may be a good fit.
