What should you know about JHS joint hypermobility syndrome?

Joint hypermobility means a joint can move beyond the usual range. Some people are flexible without trouble, while others develop symptoms when a joint is repeatedly loaded or is harder to control. JHS is an older term that is still used by some people; clinicians may use a different hypermobility-related diagnosis after considering your symptoms and examination.

Symptoms can include aching after activity, a feeling that a joint may give way, clicking, stiffness after rest, or strains that recur in the same area. The knees, ankles, shoulders, hips, hands, and spine may be involved. A clinician will consider your movement pattern, strength, coordination, injury history, and how symptoms affect daily tasks rather than judging flexibility alone.

Start with a clinical assessment if pain, instability, or repeated injuries are limiting work, sport, sleep, or ordinary movement. A physiotherapist can help you practise controlled movement, build strength around vulnerable joints, and adjust activities so the joint is supported without being forced to its end range.

Progress gradually: use comfortable ranges, focus on steady control, and allow recovery between demanding sessions. Strength work for the hips, legs, trunk, shoulders, or hands may be selected according to your symptoms. Avoid repeatedly locking or pushing a joint farther just to demonstrate flexibility. Supportive footwear, pacing, and changes to technique can also reduce aggravation.

Arrange a medical review when joint pain persists, swelling follows an injury, a joint repeatedly gives way, or weakness is interfering with normal activities. Seek urgent care for a major injury with visible deformity, sudden loss of movement, severe pain, a limb that becomes cold or discoloured, or new numbness or marked weakness.

Keep a brief record of which joint is affected, what movement triggers symptoms, whether the joint feels unstable, and how long recovery takes. This can help the clinician distinguish flexibility from a problem with joint control and tailor the examination.

Ask: Could my symptoms be related to joint hypermobility or another joint problem? Which movements should I limit or modify for now? What strength and control exercises fit my affected joints? How should I progress activity, and which changes would mean I should return sooner?
