Introduction
In general, exercises such as push-ups, pull-ups, tennis, badminton, and rock climbing may cause numbness in the thenar eminence (虎口). If symptoms persist or worsen, timely medical consultation is recommended for accurate diagnosis and appropriate treatment. It is advisable to perform adequate warm-up and stretching exercises, especially for the hands and wrists. Additionally, using correct posture and techniques during physical activities and avoiding prolonged maintenance of the same posture are recommended.
Generally, exercises such as push-ups, pull-ups, tennis, badminton, and rock climbing may cause numbness in the thenar eminence (the fleshy part of the palm below the thumb). If symptoms persist or worsen, timely medical consultation is recommended for accurate diagnosis and appropriate treatment options. Detailed explanations are as follows:
1. Push-ups
When performing push-ups, incorrect posture, such as excessive outward or inward positioning of the hands, or over-flexion or extension of the wrists, can compress the nerves in the wrist area. This may lead to compression of the median or ulnar nerve, causing numbness in the thenar eminence.
2. Pull-ups
During pull-ups, if the grip on the bar is excessively tight or sustained for a long time, it may compress the nerves and blood vessels in the hand, affecting nerve conduction and resulting in numbness in the thenar eminence.
3. Tennis
Playing tennis involves frequent rapid flexion, extension, and rotation of the wrist and forearm during strokes. Incorrect grip techniques, such as gripping the racket too tightly or loosely, may place excessive pressure and torsion on the wrist during strokes, potentially damaging the wrist nerves and causing numbness in the thenar eminence.
4. Badminton
While playing badminton, frequent wrist movements are required for various strokes, such as smashes and drop shots. Improper wrist mechanics during strokes may increase pressure within the carpal tunnel, compressing the median nerve and causing numbness in the thenar eminence and other areas of the hand.
5. Rock Climbing
During rock climbing, the hands must bear much of the body's weight and tightly grip rocks or handholds. Inappropriate gripping techniques or prolonged suspension on the wall can cause excessive tension in the hand muscles, placing significant pressure on the nerves and blood vessels in the hand, leading to numbness in the thenar eminence.
It is recommended to perform adequate warm-up and stretching exercises, especially for the hands and wrists. Additionally, use proper posture and techniques during exercise, and avoid maintaining the same position for prolonged periods.
