HPO HP:0002515 Waddling gait "Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck."

HPO HP:0002804 Arthrogryposis multiplex congenita "Multiple congenital contractures in different body areas." [HPO:probinson, PMID:23050160] Arthrogryposis multiplex congenita (AMC) consists of several conditions of different etiology and mixed clinical features, including multiple congenital contractures in multiple body areas. Here, we use the term to refer solely to the multiple congenital contractures. It is related to fetal akinesia owing to fetal neurogenic, muscle, or connective tissue disorders or occasionally to maternal conditions. AMC can be associated with polyhydramnios, pulmonary hypoplasia, micrognathia, ocular hypertelorism, and short umbilical cord. AMC is a feature of a heterogeneous group of disorders, some of which have the phrase 'arthrogryposis multiplex congenita' as a part of their name (for instance, Arthrogryposis multiplex congenita, distal type 1 or AMCD1). This term refers to the finding of multiple joint contractures found throughout the body at birth rather than to the disease entities of which this is a clinical feature. HP:0002803

HPO HP:0001533 Slender build "Asthenic habitus refers to a slender build with long limbs, an angular profile, and prominent muscles or bones." [HPO:probinson] Slender, long-limbed habitus. HP:0000098, HP:0004325
HPO HP:0001290 Generalized hypotonia "Generalized muscular hypotonia (abnormally low muscle tone)." [HPO:curators] HP:0001252
HPO HP:0001761 Pes cavus "The presence of an unusually high plantar arch. Also called high instep, pes cavus refers to a distinctly hollow form of the sole of the foot when it is bearing weight." [HPO:probinson, PMID:19125433] HP:0001760
HPO HP:0003306 Spinal rigidity "Reduced ability to move the vertebral column with a resulting limitation of neck and trunk flexion." [HPO:probinson, PMID:11601420, PMID:2246660] HP:0000925
HPO HP:0000508 Ptosis "The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective)." [PMID:19125427] HP:0012373
HPO HP:0003690 Limb muscle weakness "Reduced strength and weakness of the muscles of the arms and legs." [HPO:sdoelken] HP:0001324, HP:0009127
HPO HP:0003798 Nemaline bodies "Nemaline rods are abnormal bodies that can occur in skeletal muscle fibers. The rods can be observed on histological analysis of muscle biopsy tissue or upon electron microscopy, where they appear either as extensions of sarcomeric Z-lines, in random array without obvious attachment to Z-lines (often in areas devoid of sarcomeres) or in large clusters localized at the sarcolemma or intermyofibrillar spaces." [HPO:curators, PMID:11333380] This finding can be demonstrated by muscle biopsy, which shows nemaline bodies (rods) on Gomori trichrome staining. Rod bodies characteristically stain red with\nMGT. The rods are delicate and accumulate subsarcolemmaly. They stain negative with ATPase, NADH and SDH as they lack myosin and mitochondria. Rods are characteristic of nemaline myopathy but also seen in central core disease and various other diseases which include neurogenic disorders (amyotrophic lateral sclerosis, spinal muscular atrophy, undefined), inflammatory myopathies (dermatomyositis, polymyositis, periarteritis nodosa), metabolic myopathy (mitochondrial myopathy), muscular dystrophy (LGMD) and some undefined myopathies (Liouet al; Diagnostic role of nemaline rod in neuromuscular disease. Acta Neurol Sinica 1992;1: 218-23). HP:0100303
