Musculoskeletal review - end feels, gait, orthoses, ROM, and prosthetics Flashcards
Normal End Feel types
Firm, Hard, Soft
Abnormal End Feel Types
Empty, firm, hard, soft, boggy
Firm end feels
Should feel like a stretch
Normal examples: DF, finger extension, hip medial rotation, forearm supination
Abnormal examples: increased tone, tightening of the capsule, ligament shortening
Hard end feels
Bone to bone
Normal: elbow extension
Abnormal examples: fracture, osteoarthritis, osteophyte formation, HO, MO
Soft
Soft tissue approximation - normal
Normal examples: elbow and knee flexion
Abnormal examples: edema, synovitis, ligament instability/tear
Emty:
Due to pain: joint inflammation, fracture, bursitis
Standard Terminology for Gait (not RANCHO)
Stance:Heel strike, foot flat, midstance, heel off, toe off
Swing: acceleration, midswing, deceleration
Peak muscle activity of tibialis anterior during gait
After heel strike - eccentric lowering of the foot (1st rocker)
Peak muscle activity of the gastroc-soleus during gait
During late stance phase, responsible for concentric raising of the heel during toe off (terminal stance)
Peak muscle activity of the quadriceps group
Two periods: in periods of single support during early stance phase and just before toe off to initiate swing phase
Peak activity of the hamstrings group during gait
During late swing phase for decceleration of the swing limb
Average BOS
2-4 inches for an adult. Decreases as speed increases
Cadence
110-120
Degrees of toe out
Angle formed by intersecting heel and second toe. 7 degrees
Step length
13-16 inches
Stride length
24-32 inches likely (56 inches?)

Solid ankle foot orthoses
Control DF/PF and IV/EV. Can be articulating or not. Articulation allows the tibia to advance over the foot. Trim line is anterior to the medial malleolus
Posterior leaf spring AFO
Plastic AFO with trim line posterior to the malleoli. Assists with DF and prevents foot drop. Requires adequate medial/lateral control by the patient.
Floor reaction AFO
Assists with knee extension during stance through positioning of calf band and or positioning of ankle
Corset
Spine orthosis - constructed of fabric. Abdominal compression and support. Utilized to provide pressure and relieve pain associated with mid and low back pathologies
Milwaukee Orthosis
For realignment of spine due to scoliotic curvature. Pelvis to upper chest with corrective padding
TLSO
Prevents all trunk motions - common for post-surgical stabilization
Symes amputaton
surgical removal of the foot and the ankle joint including the malleoli
Chopart disarticulation
Disarticulation at the midtarsal joint
Prosthetics: Causes of lateral bending
Prothesis too short, improperly shaped lateral wall, high medial wall, prothesis aligned in abduction
Poor balance, abduction conracture, short residual limb, weak hip abductors, hypersnsitive and painful residual limb
Prosthetics: Causes of abducted gait
Prothesis too short, high medial wall, poorly shaped lateral wall, prothesis positionined into abduction, inadequate suspension, excessive knee friction
Abduction contracture, adductor roll, weak hip flexors and adductors, pain over lateral residual limb
Prothetics: Causes of circumducted gait
Prothesis too long, too much friction in the knee, socket too small, excessive PF of foot
Abduction contracture, weak hip flexors, difficulty flexing knee, painful anterior distal residual limb
Prosthetics: Causes of excessive knee flexion during stance
Socket set forward in relation to foot, foot set in excessive DF, stiff heel, prothesis too long
Knee or hip flexion contracture, pain anteriorly in residual limb, decreased quad strength, poor balance
Prosthetics: Causes of vaulting
Prothesis too long, inadequate socket suspension, excessive alignment stability, foot in increased PF
Residual limb discomfort fear of stubbing toe, short residual limb, painful hip/residual limb
Rotation of forefoot at heel strike
Excessive toe-out buitl in, loose fitting socket, inadequate suspension, rigid SACH heel cushion
Poor muscle control, weak medial rotators, short residual limb
Forward trunk flexion
Socket to big, poor suspension, knee instability
Hip flexion contracture, weak hip extensors, pain with ischial weight baring, inability to initiate prosthetic knee flexion
Medial or lateral whip
Excessive roation of the knee, tight socket fit, valgus in the prosthetic knee, improper alginment of toe break
weak hip rotators, knee instability
A long prothesis can cause:
Circumduction, abducted gait, excessive knee flexion during stance, contralateral vaulting
A short prothesis can cause:
Lateral bending
A stiff heel can cause:
Excessive knee flexion during stance
A high medial wall can cause:
Lateral bending or abducted gait
Inadequate suspension can cause
Abducted gait, rotation of forefoot at heel strike, vaulting, forward trunk flexon
A poorly shaped lateral wall may cause:
Lateral bending, abducted gait
Pain in the residual limb (based on location) may cause: Ant vs lateral vs overall hypersensitivity
Hypersensitive limb/overall pain: lateral bending or vaulting
Lateral pain: abducted gait
Anterior pain: Circumducted or excessive knee flexion during stance
