Core Viewpoint - Skiing has become a popular choice for family outings during the Spring Festival, but it carries risks of skeletal and joint injuries, highlighting the importance of protective measures and proper equipment selection for bone health [1][3]. Group 1: Skiing Safety and Preparation - Skiing requires high levels of coordination and balance, especially for first-time skiers, making them more susceptible to falls and injuries [3]. - Proper warm-up exercises are essential to activate joints and muscles, reducing the risk of strains and sprains during skiing [3]. - Targeted protective gear is crucial, with specific emphasis on protecting vulnerable areas such as the hips, wrists, and knees [4]. Group 2: Protective Gear Recommendations - Specialized protective pads, such as soft crash pads for the hips and hard wrist guards, are recommended to mitigate injury risks during falls [4]. - Ski equipment must fit properly; ill-fitting boots and boards can increase the likelihood of falls [5]. - Beginners should start on easier slopes under professional guidance to learn basic techniques and reduce injury risks [5]. Group 3: Daily Joint Care and Support - Long trips and activities like hiking can increase stress on joints, making the selection of appropriate supports crucial for joint health [8]. - Knee braces should be chosen based on the severity of joint issues, with custom medical-grade supports recommended for serious conditions [8]. - For back support, a double-layered waist support is advised, but it should not be worn continuously to avoid muscle atrophy [8]. Group 4: Orthopedic Aids Usage Tips - The selection of orthopedic aids should be guided by professionals, and expensive options are not necessarily better [11]. - Gradual weaning off supports is important to prevent muscle weakness, and adjustments to custom aids should only be made by healthcare providers [11]. - For children recovering from ankle fractures, the choice of support should consider their cooperation level, balancing fixation and mobility [11].

Core Viewpoint - The article emphasizes the importance of proper techniques and equipment for hiking to prevent injuries, particularly to the joints and back, during the autumn season when many people engage in outdoor activities [1][3]. Group 1: Hiking Techniques - Hiking is not simply walking; it involves specific movements that can put unique stress on the joints, especially during uphill and downhill activities [3][4]. - Proper techniques for uphill hiking include ensuring the knees do not extend beyond the toes, avoiding inward knee rotation, and maintaining a neutral spine to prevent excessive pressure on the knees and lower back [5][6][7]. - For downhill hiking, it is advised to land on the forefoot rather than the heel, avoid loose footwear, and consider using a sideways or S-shaped descent to distribute impact forces [8][9][11]. Group 2: Equipment Recommendations - The article suggests that protective gear should be chosen based on specific needs rather than an abundance of equipment, as incorrect choices can lead to increased wear and tear [12]. - Essential equipment includes trekking poles for balance and reduced joint pressure, knee braces for targeted support, and well-fitted hiking shoes that provide ankle stability and grip [13][14][16]. - It is recommended to ensure shoes fit snugly and to use ankle supports if there is discomfort to prevent further injury [18]. Group 3: Injury Signals and Emergency Response - Four serious signals indicating the need to stop hiking include hearing a "pop" sound during an injury, rapid swelling of the joint, visible bruising, and pain during joint movement even without weight [19]. - The article outlines the PRICE principle for emergency response: Protection, Rest, Ice, Compression, and Elevation, emphasizing the importance of seeking medical evaluation before resuming hiking activities [20].
